我想在While循环中执行我的选择查询,但它不起作用。
Set @i = 1
While(@i <= @rowNumber)
BEGIN
Set @q_getoldeMail = 'SELECT Lower('+@columnname+') FROM (
SELECT ROW_NUMBER() OVER (ORDER BY ID) AS rownumber
,ID
,[Name]
,[Description]
,[Status]
,[AssignedTo]
,[AssignedToMail]
,[CC]
FROM ' + QUOTENAME(@tablename) + ') AS ar Where rownumber = '+@i+''
exec sp_executesql @q_getoldeMail, N'@get_oldeMail nvarchar(100) output', @get_oldeMail output
Set @i = @i+1
在其他方面,我尝试执行查询而不使用while循环:
Set @q_getoldeMail = 'SELECT Lower('+@columnname+') FROM (
SELECT ROW_NUMBER() OVER (ORDER BY ID) AS rownumber
,ID
,[Name]
,[Description]
,[Status]
,[AssignedTo]
,[AssignedToMail]
,[CC]
FROM ' + QUOTENAME(@tablename) + ') AS ar Where rownumber = '+@i+''
exec sp_executesql @q_getoldeMail, N'@get_oldeMail nvarchar(100) output', @get_oldeMail output
它也不起作用。我的错是什么?有没有办法通过While循环从Select
语句中获取值?你能救我吗?
编辑:
我在此代码部分设置了@rowcount值:
SET @q_getrowNumber = 'SELECT Count(ID)
FROM dbo.' + quotename(@tablename) + ''
execute sp_executesql @q_getrowNumber, N'@rownumber int output', @rownumber output
此代码部分返回值(112)。但是当我改变@rowcount
时Set @rowcount = 2
然后代码工作。我尝试转换为整数@rowcount但它没有工作

可能这就是你要找的东西 -
