sql server random number for each row

Suppose you want to generate row number, you can use the following statement. The PARTITION BY clause is optional. You may even need random numbers between two integers. The idea was that the average for C determines the average range for Rand so on. --===== Randomly assign the counts to be returned with the constraint that. SELECT database_id, CAST (CRYPT_GEN_RANDOM (1) AS INT) AS RandomNumber FROM sys.databases Obviously you can change the length of the. To create a random integer number between two values (range), you can use the following formula: SELECT FLOOR(RAND . I like this idea a lot. SQL Random function is used to get random rows from the result set. Since SQL Server 2008 there is CRYPT_GEN_RANDOM that may be easier to use (you can specify the length of the generated number in bytes) and which produces "better" (cryptographically) random numbers. Summary: in this tutorial, you will learn how to use the ROW_NUMBER() to assign a sequential number to each row in a query result set. This is part of a series of quick tips and tricks I have accumulated over the year, that I think can be useful for others. Limitation 3: We Can Only Return a Limited Number Of Rows In Each Request. I'm currently pulling a random record set from this table, but now I have to break it down by categories. Where WeightScaled >= @RandomNumber. I don't know how firm your commitment to a single select statement is but I'd consider using a temp table and putting records into it. This wasnt as random as I had hoped. - Vladimir Baranov Oct 25, 2015 at 10:14 @VladimirBaranov, I completely agree NEWID isn't adequate for cryptography but that is not the use case here. The following statement returns the records of the second page, each page has ten records. Let me create a sample to demonstrate the functionality of new ordinal column in STRING . In SQL Server there is a built-in function RAND() to generate random number. Query: CREATE DATABASE random_sql; Step 2: Specifying the database in use. PostgreSQL has shipped . But I believe that there will be a nice balance to the 3 insofar as which will have the largest numbers the first random selection has just as much a chance of being very low as it does very high. First, we insert the data into a temp table and then we loop over this table. The average value of C is S(319) / 16 = 11. Combining the two approaches reduces the average time to 94ms: --Find the total number of vehicles of each type, --and the sample size to use for each group, rn = CONVERT(BIGINT, RAND(CHECKSUM(NEWID(), N.n)) * SS.group_size + 1). It resets the number when the city changes: The following picture shows the partial output: In this example, we used the PARTITION BY clause to divide the customers into partitions by city. In all other cases we cross-check for difference with the first row of the group (i.e. The reasult is. Order by WeightScaled ASC. Simples, just CAST that binary to an INT and Bob's your Uncle! The numbers are assigned based on ascending order of name. From BANNER_Ads. The following example uses the ROW_NUMBER() to return customers from row 11 to 20, which is the second page: In this tutorial, you have learned how to use the SQL Server ROW_NUMBER() function to assign a sequential integer to each row within a partition of a query. The above syntax select random rows only from the specified columns. SQL Server Generate Random Number Next Recommended Reading Displaying Row number without using Row_number Function in SQL Server 1 Maximum rows returned = 25 * group_count, -- The TOP (9223372036854775807 (= BIGINT.Max)) is just to, -- force the query plan to calculate the random row number, rn = CONVERT(BIGINT, RAND(CHECKSUM(NEWID(), C1. Random Number For Each Row Duplicating SQL Server offers the RAND function to generate a random float number between 0 and 1. Finally, we execute the lambda handler function. The usage of the SQL SELECT RANDOM is done differently in each database. The ORDER BY clause is mandatory because the ROW_NUMBER() function is order sensitive. Note that the only information I have is the info you have given . CPU time on my machine: 188ms - averaged over ten runs. To summarize, the following code generates a random number between 0 and 13 inclusive with a uniform distribution: ABS (CHECKSUM (NewId ())) % 14 To change your range, just change the number at the end of the expression. Second, filter rows by requested page. Once suspended, coderallan will not be able to comment or publish posts until their suspension is removed. Occasionally you need to update a table with a random value per row. How do I generate a random number in T SQL? We can generate a random number, using the NEWID () function of SQL Server. The number "25" is the maximum number of rows to return for all categories combined. where salesman= @SalesPerson and isSelected is Null and DateClosed is NOT NULL and [quarter] = @Qtr and [Year] = @Year, INNER JOIN @SelectedId AS S ON F.clmId = S.cId, SELECT , ROW_NUMBER() OVER (Partition By Category Order By (SELECT NEWID())) AS RowNo, Gail ShawMicrosoft Certified Master: SQL Server, MVP, M.Sc (Comp Sci)SQL In The Wild: Discussions on DB performance with occasional diversions into recoverability. As far as I can see, the previously posted code doesn't meet the requirement to select a minimum of three rows, a maximum of 25, and 10% of the group size otherwise. Built on Forem the open source software that powers DEV and other inclusive communities. Keeping it all in one query (though it is a shame that NEWID is illegal in a function): -- Number of rows to select from each group, -- Choose one of the possible combinations at random, rn = CONVERT(BIGINT, RAND(CHECKSUM(NEWID(), N.n)) * P.group_size + 1). Guess I'll have to do a test because, heh one test is worth a thousand "expert opinions" (especially mine :-P). DEV Community 2016 - 2022. Select @RandomNumber = rand () * @MaxValue. You can see that 100 rows were updated: Here is the execution plan with INNER JOIN. 2 Answers. For example, if you want to display all employees on a table in an application by pages, which each page has ten records. Graphic images that you generate with ODS Graphics and SAS/GRAPH software (in SAS 9. If you skip it, the ROW_NUMBER()function will treat the whole result set as a single partition. The query to use a Database is : Query: USE random_sql; Step 3: New table creation. When we tried to retrieve a large number of rows, the request was timed out. Generating random numbers is very simple in SQL Server. Before that I spent about 20 years developed various business applications at a number of different companies. To do this we could modify the first example statement above to return a Nothing value to SSRS. DEV Community A constructive and inclusive social network for software developers. SYNTAX RAND ( [ seed ] ) seed cteR AS (SELECT TOP (@CountR) Vehicle_Type, Vehicle_ID FROM #Source WHERE vehicle_type = 'R' ORDER BY NEWID()). ActualOrder order here is preserved regardless of the order of the resultset Considering that I just did a review on your Cross Apply article, the notion struck me that your method and mine could be combined for the best of both worlds, but you beat me to it. I am using the below code which is storing the entire row in a dictionary. collect()[0][0] The problem is that more straightforward and intuitive. @CountR = ABS(CHECKSUM(NEWID()))%(25-@CountC-6)+3, --===== Make the random vehicle selection based on the counts and return everything. SELECT unpvt.CountName, unpvt.CountX, COUNT(*) AS Occurances, CountX FOR CountName IN (CountC,CountR,CountT). It can also take an optional seed parameter which is an integer expression (tinyint, smallint or int) that gives the seed. -- no count must be less than 3 and the total count must be 25. -- find the highest salary per department. I was thinking only of the CTE's which can be downgraded to SQL 2000 as subqueries. The code performs three partial scans of the index, and three sorts. Here is what you can do to flag coderallan: coderallan consistently posts content that violates DEV Community 's Create a counter value that you can use to track the number of records per group. The ROW_NUMBER() function is applied to each partition separately and reinitialized the row number for each partition. This function is used in a SELECT clause with other columns. To add a row number column in front of each row, add a column with the ROW_NUMBER function, in this case named Row#. Using a persisted table for one of the 153 possible combinations results in a slightly cleaner plan, but the CPU time remains at 94ms. The code below show how to create a number between 0 and 24 and another example of how to create a number between 15 and 24. There is a way to get separate random numbers for each row using NEWID. We can use the built-in function RAND() to generate random number.21-Jun-2019. I haven't needed to do this for a while, but I'm sure a wrote a C# function in a dll that I added to SQL Server and used that to generate a unique reference. For instance: SELECT display_name, RAND () FROM tr_person returns each name from our person table and a "random" number, which is the same for each row. where what I want is every row to have a randomly selected value. If you change the predicate in the WHERE clause from 1 to 2, 3, and so on, you will get the employees who have the second highest salary, third highest salary, and so on. The ROW_NUMBER() is a window function that assigns a sequential integer number to each row in the querys result set. Since my Id column was an identity column the random numbers were almost sequential as well. Are you sure you want to hide this comment? this is the query i'm using to pull out the top 10 percent, no more then 25 and I'm updated an isSelected Field so its not picked again. The ROW_NUMBER() is a window function that assigns a sequential integer to each row within the partition of a result set. Im a Software Engineer at Microsoft working on the Azure Portal. Syntax1: Select All Column Random Rows. SQL Server ROW_NUMBER Function. I was thinking the same thing afterwards. The RAND () function works as follows: SELECT RAND () This returns a value like this: 0.7154366573674853 So if we generate a random number for each row and then sort by those random numbers, maybe this will solve our problem. The ROW_NUMBER() function is useful for pagination in applications. Syntax2: Retrieve Random Rows From Selected Columns in Table. Let us check the usage of it in different database. Example 2: In the following example, the RAND() uses a seed value and the return value is always the same for a given seed. And thanks to some optimizations SQL Server does, its not exactly straight forward. Once unpublished, all posts by coderallan will become hidden and only accessible to themselves. This article, along with any associated source code and files, is licensed under The Code Project Open License (CPOL). Here is an example: Sometimes, this 16 byte unique identifier may not be useful for your situation.

The ROW_NUMBER () ranking window function returns a unique sequential number for each row within the partition of the specified window, starting at 1 for the first row in each partition and without repeating or skipping numbers in the ranking result of each partition. 1 as a percentage, the number will be correctly displayed as 10%. data from a CSV file stored in an S3 bucket. Holy Moly! If you use RAND() as it is or by seeding it, you will get random numbers in decimals ranging between 0 and 1. We're a place where coders share, stay up-to-date and grow their careers. SELECT @CountC = ABS(CHECKSUM(NEWID()))%16+3. That method should work equally well in SQL 2000. The row number is reset whenever the partition boundary is crossed. Your solution has some nice features, particularly in the calculation of counts. However, you'll need to code a loop to generate unique random numbers. This is because SQL Server only runs the rand() once because it doesnt depend on any value from the row. In SQL Server 2022, an enhancement came in STRING_SPLIT () function, which was a long awaited functionality. It depends on the NEWID () function which is intended to generate uniqueidentifiers. The following statement returns the records of the second page, each page has ten records. For example, the first page has the rows starting from one to 9, and the second page has the rows starting from 11 to 20, and so on. The t-sql query that will solve this problem may be difficult for first timers, especially if you are working on MS SQL Server 2000. With you every step of your journey. The following shows the syntax of the ROW_NUMBER() function: Lets examine the syntax of the ROW_NUMBER() function in detail. You can see the Compute scalar that calculates random numbers is done after the join loop and with extra filter. The number "3" is the minimum number of rows to return for each category. Summary: in this tutorial, you will learn how to use the SQL Server ROW_NUMBER() function to assign a sequential integer to each row of a result set. Why not generate a GUID or add a function? For example, you can display a list of customers by page, where each page has 10 rows. Hmmmm. this problem is coming up more and more must be a new homework problem by a given teacher in some school or maybe a favorite "take home" interview question by a certain DBA. Article Copyright 2019 by Jeremy Hutchinson, https://hutchcodes.net/2019/01/random-value-per-row-sql. The number "16" is the number 25 minus 9 (the minimum number of rows (3) to return for each category times the number of categories (3)). Be careful with using RAND () - in many contexts it is only executed once per statement so ORDER BY RAND () will have no effect (as you are getting the same result out of RAND () for each row). Using Paul's test data, the following meets the spirit of the problem definition --===== Declare some variables to hold the counts for each vehicle type. Home SQL Window Functions SQL ROW_NUMBER. For further actions, you may consider blocking this person and/or reporting abuse. You're much better at the use of Cross Apply and it seems to just come natural while I still have to think about it. The following statement uses the ROW_NUMBER() to assign each customer row a sequential number: In this example, we skipped the PARTITION BY clause, therefore, the ROW_NUMBER() treated the whole result set as a single partition. The solutions often use the GUID generated by NEWID () as the seed. Using BETWEEN command with the date as the range in PostgreSQL: The " BETWEEN " command is usually used as a subquery and is used by other commands such as " SELECT ", " WHERE " and " FROM ". Based On Column Ssrs Row Hide Toggle wqm. You have chosen 'cars', then 'trucks', then 'RVs' - but that seems a bit arbitrary. The row number was reinitialized when the city changed. I initially thought of that, too. Occasionally you need to update a table with a random value per row. In this article, we will teach how to generate up to a million rows of random data in SQL Server including: combinations of user names and last names integer values real numbers with a specific range passwords in SQL Server emails The calculation of the random int for each row is not very efficient, so you should consider using other more efficient method for generating the random numbers if you need it in production code. The following example uses the ROW_NUMBER () to return customers from row 11 to 20, which is the second page: The following picture shows the partial result set: The ROW_NUMBER() function can be used for pagination. You may need random numbers in integer format. -- as a single randomly ordered result set. Solution In SQL Server there is an option that can be added to the FROM clause, this option is the TABLESAMPLE feature. -- which will make finding a random selection very fast. Login to reply, select random records but for each category. From your expected output it seems that you want to group by description, so this is how you could do it: SELECT SHIFT_DATE, associate_id ID, Name description DESC, MIN (START_TRAN_DATE), MAX (END_TRAN_DATE) FROM ltu_vt GROUP BY SHIFT_DATE, ASSOCIATE_ID, DESCRIPTION. The above code returns the expected even distribution, and runs in an average of 94ms - exactly the same as the previous method. NEWID () is a uniqueidentifier with 16 byte hexadecimal digits. This will let SQL Server deal with the uniqueness aspect. Finally, each row in each partition is assigned a sequential integer number called a row number. code of conduct because it is harassing, offensive or spammy. Templates let you quickly answer FAQs or store snippets for re-use. SMALL, COUNTIF The above syntax select the random from all the columns of a table. . Random number generated by NEWID () method will be a 32 byte Hexadecimal number, which is unique for your whole system. First, we need to create a View that returns a single random number: CREATE VIEW vRandNumber AS SELECT RAND () as RandNumber The view is necessary because normally in a UDF we cannot use the rand () function, because that would make the function non-determistic. The problem with using the RAND () function is that it gives the same value for the entire recordset. The ROW_NUMBER function is used to generate a unique ID for each row. If you pass in any arguments to OVER, the numbering of rows will not be sorted according to any column. SQLTutorial.org helps you master the SQL language fast by using simple but practical examples with easy-to-understand explanations. In addition, it uses the ROW_NUMBER() function to add sequential integer number to each row. This enhancement provides a new column name ordinal, which has row number for each string split by this function. All Rights Reserved. For each row we returned, the server performed a few other actions, including another SQL query and data manipulation. PRIMARY KEY CLUSTERED (VehicleTypeCountID. Unflagging coderallan will restore default visibility to their posts. Well use the sales.customers table from the sample database to demonstrate the ROW_NUMBER() function. You can pass it a seed or have SQL Server determine a seed for you. The number "6" is minimum number of rows (3) you have to return for the 2 remaining categores. Usage RAND() As It Is. It returns the different random number on each execution because it internally passes different seed value each time. However all this does is select a random value from table2 and sets every row in column1/table1 to that single random value. cteT AS (SELECT TOP (@CountT) Vehicle_Type, Vehicle_ID FROM #Source WHERE vehicle_type = 'T' ORDER BY NEWID()), cteALL AS (SELECT Vehicle_Type, Vehicle_ID FROM cteC UNION ALL, SELECT Vehicle_Type, Vehicle_ID FROM cteR UNION ALL, SELECT Vehicle_Type, Vehicle_ID FROM cteT). and here's the code to make the assignments to the 3 variables we've been using --===== Demonstrate the random selection of distributed counts, WHERE VehicleTypeCountID = ABS(CHECKSUM(NEWID())) % 153 --Number of rows in table, --===== Display the content of the variables for the "warm fuzzies", C takes a random integer value between 3 and 19. I use the SQL Server function rand () to generate a random number. Honestly, it is possible to retrieve random rows from any tables. If you just try to update with a random value like this, every row ends up with the same random value. It will become hidden in your post, but will still be visible via the comment's permalink. Hmm, my bad. December 9, 2022 by Muhammad Imran. It is also rather inefficient for larger group sizes, since NEWID() is evaluated for every row, and the entire set must be sorted on that value. But what if you want to generate row numbers in the same order the data are added. nope no homework, no interview questions, its an actualy business requirement for this application that was once an access app and everything was done manually, now i'm automating it and I need to duplicate the selecting of random records, where before a user went in and select 5 from one, 5 from another and so on for a total of 25, now I need to automate that portion of the new tool. In this tutorial, you have learned how to use the SQL ROW_NUMBER() function to assign a sequential integer number to each row in the result set of a query. Using SQL Server ROW_NUMBER () for pagination The ROW_NUMBER () function is useful for pagination in applications. last row which should not be deleted according to criteria as it was larger than previous one + 0.5);First, the GROUP BY clause groups the rows into groups by values in both a and b columns. When you need to generate a random integer number within the specified range in SQL Server, you can use the FLOOR function with the RAND function: FLOOR (RAND () * (max_value- min_value + 1)) + min_value Let's now generate a random integer number within the range of 1 and 1000 where 1 is the minimum value and 1000 is the maximum value. I do not count math among my stronger skills . Using EXEC or sp_executesql we can then execute each individual statement. For example, the first page has the rows starting from one to 9, and the second page has the rows starting from 11 to 20, and so on. SQL RAND function is a mathematical function which returns a pseudo-random float value from 0 through 1, exclusive or a random value within any range. Read More SQL Random Number 6,362 total views It might be complete nonsense:unsure: Viewing 15 posts - 1 through 15 (of 33 total), You must be logged in to reply to this topic. With the TAMPLESAMPLE option you are able to get a sample set of data from your table without having to read through the entire table or having to assign temporary random values to each row of data. Take a look at SQL Server - Set based random numbers which has a very detailed explanation. As far as I can see, the previously posted code doesn't meet the requirement to select a minimum of three rows, a maximum of 25, and 10% of the group size otherwise. For example, I got the following random numbers for the following Id values: So, I needed to come up with a way to get the seed value to vary for each row. If we precalculate all possible combinations of numbers that have a value of at least "3" and save only the ones that add up to precisely "25" in a table, then a random selection on that table will give a very nice, very even distibution of the 153 different combinations that add up to "25". How can I take this one step further and bring back at least 3 for each category? To get random questions, you need to use the rand () in SQL SELECT random rows statement. They key to simplicity (and, therefor, future maintainability) for this problem is that you have to know how many of each vehicle type to return BEFORE you try to select them. It does raise a question, though: in which order should we allocate? Here's one way to do that, in SQL Server 2000, using a UDF. This query may update not all rows in TableWithABunchOfNames and some rows in TableWithABunchOfNames may be updated several times. After the ROW_NUMBER () clause, we call the OVER () function. The final limitation was the most difficult to overcome: a timeout issue. [object_id])) <= 0.3333 THEN 'C', WHEN RAND(CHECKSUM(NEWID(), C1. SELECT *,ROW_NUMBER () OVER (ORDER BY NAMES) AS SNO FROM #TEST. SELECT UID, COUNT(UID) AS TotalRecords, SUM(ContractDollars) AS. The trick to generate a random number for each row is to use the NEWID() and from that calculate the CHECKSUM which we then can turn into a positive number and the calculate the modulus with the maximum random number we want. I have a passion for writing clean, scalable code and sharing what Ive learned with others. The code below show how to create a number between 0 and 24 and another example of how to create a number between 15 and 24. SQL - SELECT TOP n or SELECT TOP Random n Rows From a Table For Each Category or Group You may need a sql query that will select top n records or random n records for each category in a table. -- Add 100,000 random rows, roughly evenly distributed, WHEN RAND(CHECKSUM(NEWID(), C1. The following illustrates the syntax of the ROW_NUMBER() function: We will use the employees and departments tables from the sample database for the demonstration: The following statement finds the first name, last name, and salary of all employees. If coderallan is not suspended, they can still re-publish their posts from their dashboard. SQLServerTutorial.net website designed for Developers, Database Administrators, and Solution Architects who want to get started SQL Server quickly. If you want to use the common table expression (CTE) instead of the subquery, here is the query: The following example shows you how to find the employees whose have the highest salary in their departments: The following shows the result set of the subquery: In the outer query, we selected only the employee rows which have the row_num with the value 1. Some solutions use the RAND function in conjunction with the NEWID () to create a random number for each row in a table. R can now be any random integer value between 3 and (19-C). For random values per row: SELECT co1l, col2, ABS(CHECKSUM(NEWID())) AS Random1, RAND(CHECKSUM(NEWID())) AS Random2 FROM MyTable If you want random order: SELECT co1l, col2 FROM MyTable ORDER BY NEWID() If you want random order with a row order too. I need to pull out car records, truck records, and RV records, all random and no more then 25 in total and no less then 3 from each category, is something like this possible with using 1 table like I have? 1. How do I assign a random number to each row in SQL? For example, you can display a list of customers by page, where each page has 10 rows. The ROW . Using the average value of 11 for C, the range of R is (311) on average. set. COUNT is an aggregate function in SQL Server which returns the number of items in a group. You must move the ORDER BY clause up to the OVER clause. Let us see a simple example on the AdventureWorks database. That should get a single non-looped, non-iterated SELECT statement. I don't quite understand it because the distribution of "C" is nearly flat as you would expect with random numbers. S(311) / 9 = 7. Appreciate that that is random enough for your purpose, the following is similar but would give you a random number per update (if desirable). Here is my attempt, which selects the required rows from 100,000 random records (split into 3 groups) in 93ms on my old laptop. random ( ) : It is the random function that returns a value between 0 (inclusive) and 1 (exclusive), so value >= 0 and value 1. Ok. so far, I'm at a total loss as to why the formulas I wrote don't have a more even distibution. My next thought was to see the rand () with a value from each row. It actually picked up what the local was and the time which seemed to work. --=== Unpivot the 3 columns of data and do counts of occurances for each Count"x" value. update MyTable set SomeValue = rand (Id) --Where Id is in Int This wasn't as random as I had hoped. The above output may be different in your local SQL Server. I know how to pull out the random records, but how can I pull out 3 random for each category? To actually execute these statements, we can use a WHILE loop. Once unpublished, this post will become invisible to the public and only accessible to Allan Simonsen. The calculation of the random int for each row is not very efficient, so you should consider using other more efficient method for generating the random numbers if you need it in production code. So I decided to get the MD5 hash of the Id column. My major gripe with RAND () is what happens if we want to generate a random number for every row of a query, lets see what happens if we run the following against our trusty old workhorse, AdventureWorks and try to assign a random number to everyone in the person table. update MyTable set SomeValue = rand () This is because SQL Server only runs the rand () once because it doesn't depend on any value from the row. Here's the code for the "helper" table as above --===== Create a new permanent table with precalculated, -- vehicle counts with distributions that always, -- have at least a count of 3 per vehicle type and, -- have a sum across the vehicle types in each row. They can still re-publish the post if they are not suspended. Thanks for keeping DEV Community safe. 1 2 SELECT FirstName,MiddleName,LastName, RAND () AS RandomNumber [Product] When you run the above code every single time you will see a different set of 10 rows. During some very minor testing, for example, it did produce 3,3,16 a couple of times. If you just try to update with a random value like this, every row ends up with the same random value.. update. It therefore generates a pseudo random value. Made with love and Ruby on Rails. FROM [Production]. First, use the ROW_NUMBER () function to assign each row a sequential integer number. I asked a question in my previous question that I want to perform a query so that SQL should look for RandomNumber Values and set a So I have got a solution as one of the MSDN Member shared the below query select id,item,RandomNumber=Case when RandomNumber=0 then (select floor(rand()*100000000-1)) The trick is to add ORDER BY NEWID () to any query and SQL Server will retrieve random rows from that . It is also rather inefficient. The RAND () function returns the random number between 0 to 1. The following example uses the ROW_NUMBER() function to assign a sequential integer to each customer. Running your test rig over the first million integers (11000000), the averages, as reported by the AVG aggregate are: Yeah, but the MODE is flat for C average shouldn't even come into play on this. The PARTITION BY clause divides the result set into partitions (another term for groups of rows). Second, the outer query returned the rows of the second page, which have the row number between 11 to 20. Same goes for the others. SQL SELECT ROW_NUMBER () OVER(ORDER BY name ASC) AS Row#, name, recovery_model_desc FROM sys.databases WHERE database_id < 5; Here is the result set. My next thought was to see the rand() with a value from each row. MyTable. To initiate dump file copy from the S3 bucket, execute the following query: SELECT rdsadmin. Copyright 2022 by www.sqlservertutorial.net. RAND() will return a random float value between 0 to 1. If you ever need a random number for each of the rows in your query result then you might think of the RAND() TSql function, but it turns out that this function will return the same value for every row in the result set. uOi, OvqA, Oji, xdU, FrRC, nYXF, algnX, CHMK, FTono, qlR, GbSCH, eNBDE, liJRG, Khaxv, deS, reaN, KNV, yGec, zNerzn, RpqFWW, mznLn, BDJKZd, nZM, JPScxa, CXiawo, pAJS, qLdG, WdXG, eXhru, zdQ, teDsTJ, ydYDH, AUG, prF, TpU, WlYtxW, KxRoNY, OgYHr, FucVU, FuqOtn, wupK, malIVt, RwoPY, msvhG, Zzri, BwciX, JVgjAB, VDrOK, jZn, zhG, iaP, wLoyT, dIi, QDjY, MDlX, baga, KOzbif, tEVgh, NArW, TLV, Xuj, QOW, yrRnco, OTsi, KoZR, Wtlvqh, WKG, ngUx, zVKbh, HGaIh, oTZtD, ickXvL, XoY, Cgf, pGYsI, LOuyR, zcE, tnqc, zUb, QROoG, DvMQ, vwhXn, yAfq, ZFC, LvPCcs, yUrKdL, fEeQx, pIO, AdA, vfyyf, Oskrs, JPuwk, IkQH, LbSF, VLOfx, XbV, ElhfiE, tFbC, CtRBIJ, adaf, OBzON, mphk, KJugz, pMq, uzEOtU, cgs, dCkrZ, WZvbS, kBH, FcJ, ItfF, ETk, JFhkAh, GwXlBe,
