Tbl_Campaigns（要插入的表格）

键|名字|日期| organisation_1 | organisation_2 | organisation_3 |等........

我需要从'tbl_Organisations'获取5个唯一/随机记录，捕获它们并将它们与输入到存储过程的数据一起插入到单个记录中。我理解数组不是SQL2005（？）中的一个选项。

那么我如何捕获这些记录，然后将它们作为单个记录与SP输入一起插入？

我将非常感谢任何帮助，因为我正在努力掌握SQL的复杂性

感谢。

Answer 1

可以通过在查询结尾处将ORDER BY NEWID()添加到第二个表来拉取随机记录。当然，在开头使用TOP 5只返回5行。

然后在返回的行中使用SQL游标循环来填充将在第一个表的最终插入中使用的5个静态变量（@var1，@var2等）。您将不得不使用循环计数器和一些CASE语句来确定每个运行循环的变量。最后，请确保处理返回少于5行的情况，如果可以使用您的数据集。

Answer 2

如果你有一个顺序数字键（如身份），并且从不删除任何行或回滚任何事务，这应该工作。你没有发布很多细节，所以这只是一个猜测，你可以根据你的代码。如果删除行，则可以使用ROW_NUMBER（）使类似方法起作用。

来自here，试试这个：

DECLARE @Random1 INT;
DECLARE @Random2 INT;
DECLARE @Random3 INT;
DECLARE @Random4 INT;
DECLARE @Random5 INT;
DECLARE @Upper INT;
DECLARE @Lower INT

---- This will create a random number between 1 and count() of table
SET @Lower = 1 ---- The lowest random number
SELECT @Upper= COUNT(*) FROM Tbl_Organisations ---- The highest random number
SELECT @Random1 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)
SELECT @Random2 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)
SELECT @Random3 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)
SELECT @Random4 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)
SELECT @Random5 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)

INSERT INTO Tbl_Campaigns (...., organisation_1,organisation_2,organisation_3...)
SELECT
    ...., t1.organisation_name, t2.organisation_name,t3.organisation_name...
    FROM Tbl_Organisations            t1
        INNER JOIN  Tbl_Organisations t2 ON t2.key=@Random2
        INNER JOIN  Tbl_Organisations t3 ON t3.key=@Random3
        INNER JOIN  Tbl_Organisations t4 ON t4.key=@Random4
        INNER JOIN  Tbl_Organisations t5 ON t5.key=@Random5
    WHERE t1.key=@Random1

编辑基于需要使用row_number（）

试试这段代码：

--set up tables
DECLARE @Tbl_Organisations table (O_KeyID int not null primary key identity(1,1), organisation_name varchar(20) not null)
DECLARE @Tbl_Campaigns table (C_KeyID int not null primary key identity(1,1), Cname varchar(10), createdate datetime, organisation_1 int, organisation_2 int, organisation_3 int, organisation_4 int, organisation_5 int)

--set up data
INSERT INTO @Tbl_Organisations VALUES ('one')
INSERT INTO @Tbl_Organisations VALUES ('two')
INSERT INTO @Tbl_Organisations VALUES ('three')
INSERT INTO @Tbl_Organisations VALUES ('pine')
INSERT INTO @Tbl_Organisations VALUES ('oak')
INSERT INTO @Tbl_Organisations VALUES ('maple')
INSERT INTO @Tbl_Organisations VALUES ('car')
INSERT INTO @Tbl_Organisations VALUES ('train')
INSERT INTO @Tbl_Organisations VALUES ('boat')
INSERT INTO @Tbl_Organisations VALUES ('dog')
INSERT INTO @Tbl_Organisations VALUES ('cat')
INSERT INTO @Tbl_Organisations VALUES ('horse')
INSERT INTO @Tbl_Organisations VALUES ('square')
INSERT INTO @Tbl_Organisations VALUES ('triangle')
INSERT INTO @Tbl_Organisations VALUES ('circle')

--temp areas to hold the 5 random numbers
DECLARE @Random1 INT;
DECLARE @Random2 INT;
DECLARE @Random3 INT;
DECLARE @Random4 INT;
DECLARE @Random5 INT;

--temp areas to hold the ranges to generate random numbers within
DECLARE @Upper INT;
DECLARE @Lower INT
DECLARE @range int

--get values to determine ranges of random numbers,
SET @Lower = 1 ---- The lowest random number
SELECT @Upper= COUNT(*) FROM @Tbl_Organisations ---- The highest random number
SET @Range=(@Upper - @Lower)/5


--will divide the @Tbl_Organisations table in to 5 ranges and select a random number from each range
--set the lower and upper limit on range 1
SELECT @Upper=@Lower+@Range
PRINT '@Lower='+CONVERT(varchar(50),@Lower)+', @Upper='+CONVERT(varchar(50),@Upper)
--get a random value from range 1
SELECT @Random1 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)

--set the lower and upper limit on range 2
SELECT @Lower=@Upper+1,@Upper=@Lower+@Range
PRINT '@Lower='+CONVERT(varchar(50),@Lower)+', @Upper='+CONVERT(varchar(50),@Upper)
--get a random value from range 2
SELECT @Random2 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)

--set the lower and upper limit on range 3
SELECT @Lower=@Upper+1,@Upper=@Lower+@Range
PRINT '@Lower='+CONVERT(varchar(50),@Lower)+', @Upper='+CONVERT(varchar(50),@Upper)
--get a random value from range 3
SELECT @Random3 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)

--set the lower and upper limit on range 4
SELECT @Lower=@Upper+1,@Upper=@Lower+@Range
PRINT '@Lower='+CONVERT(varchar(50),@Lower)+', @Upper='+CONVERT(varchar(50),@Upper)
--get a random value from range 4
SELECT @Random4 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)

--set the lower and upper limit on range 5
SELECT @Lower=@Upper+1,@Upper=COUNT(*) FROM @Tbl_Organisations
PRINT '@Lower='+CONVERT(varchar(50),@Lower)+', @Upper='+CONVERT(varchar(50),@Upper)
--get a random value from range 5
SELECT @Random5 = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0)


--this uses a CTE names "RowNumbers" to enumerate @Tbl_Organisations with a column "RowNumber" that is a unique sequential continueous from 1 to count(*) of @Tbl_Organisations
;with RowNumbers AS
(
    SELECT O_KeyID, row_number() over(order by O_KeyID) AS RowNumber from @Tbl_Organisations
)
--one row will be inserted, using the 5 joined in @Tbl_Organisations
INSERT INTO @Tbl_Campaigns (Cname,createdate, organisation_1, organisation_2, organisation_3, organisation_4, organisation_5)
--this will select and combine the 5 rows into 1 row, using the rownumber joined to the variables with the random values
SELECT
    'YourName'
        ,getdate()
        ,t1.O_KeyID --could be t1.organisation_name
        ,t2.O_KeyID --could be t2.organisation_name
        ,t3.O_KeyID --could be t3.organisation_name
        ,t4.O_KeyID --could be t4.organisation_name
        ,t5.O_KeyID --could be t5.organisation_name
    from @Tbl_Organisations           t1
        inner join @Tbl_Organisations t2 on t2.O_KeyID=@Random2
        inner join @Tbl_Organisations t3 on t3.O_KeyID=@Random3
        inner join @Tbl_Organisations t4 on t4.O_KeyID=@Random4
        inner join @Tbl_Organisations t5 on t5.O_KeyID=@Random5
    WHERE t1.O_KeyID=@Random1

--this shows the one row that was inserted
SELECT 'all unique',* FROM @Tbl_Campaigns
