sql – 接收错误“函数中包含的Select语句无法将数据返回给客户端”

尝试在函数中使用Select语句时收到错误.错误说明：

Msg 444,Level 16,State 2,Procedure JDE_GetWhereClause_test,Line 26
Select statements included within a function cannot return data to a client.

有任何想法吗？

CREATE FUNCTION [dbo].[JDE_GetWhereClause_test]
(
@tablename as varchar
)
RETURNS varchar(max)
AS
BEGIN
-- Declare the return variable here
Declare @Resultvar as varchar(max)

-- Add the T-sql statements to compute the return value here

set @tablename = 'F0101'
Declare @sql nvarchar(max)
Declare my_cur cursor for
    SELECT fsuser FROM dbo.JDE_ExRowSecurity where fsuser = fsuser;

Declare @fsuser as nchar(15)
open my_cur;
fetch next from my_cur;
while @@fetch_status = 0
   begin
      fetch next from my_cur into @fsuser;    
      set @Resultvar += ',' + @fsuser;
   end;
close my_cur;
deallocate my_cur;

-- Return the result of the function
RETURN @Resultvar
END

解决方法

尝试玩像……

CREATE FUNCTION [dbo].[JDE_GetWhereClause_test]
(
@tablename as varchar
)
RETURNS varchar(max)
AS
BEGIN
  -- Declare the return variable here
  Declare @Resultvar as varchar(max)

  -- Add the T-sql statements to compute the return value here

  set @Resultvar = (select STUFF((SELECT ',',fsuser as [text()]
                    FROM dbo.JDE_ExRowSecurity 
                    FOR XML PATH ('')),1,'') as blah)

  -- Return the result of the function
  RETURN @Resultvar
END

选择’答案是：'[dbo].[JDE_GetWhereClause_test](‘无论’)
