大家好,我有一个功能:
ALTER FUNCTION [dbo].[getContentURL]
(
@VID int,
@accountID int
)
RETURNS VARCHAR(500)
AS
BEGIN
DECLARE @cTable varchar(50) = '[CONTENT_CONNECT].[dbo].CONTENT_' + CONVERT(varchar(5),@accountID)
DECLARE @vTable varchar(50) = '[CONTENT_CONNECT].[dbo].VERSION_' + CONVERT(varchar(5),@accountID)
DECLARE @sql VARCHAR(max) = ''
DECLARE @RETURN VARCHAR(500)
DECLARE @ParmDefinition VARCHAR(500)
SET @sql = '
DECLARE @CompanyID int
DECLARE @RETURN VARCHAR(500)
DECLARE @ProjectNumber int
DECLARE @ContentID int
DECLARE @VersionNumber int
DECLARE @FileName varchar(400)
select @VersionNumber= V.Number,@ContentID= V.ContentID,@ProjectNumber=P.Number,@FileName=C.Name,@CompanyID=P.CompanyID
from ' + @vTable + ' V
inner join' + @cTable + ' C on V.ContentID=C.ID
inner join Project P on C.ProjectID=P.ID where V.VID='+convert(varchar,@VID)+'
select ''/''+Convert(varchar,@CompanyID)+''/''+Convert(varchar,@ProjectNumber)+''/''+Convert(varchar,@ContentID)+''/''+Convert(varchar,@VersionNumber)+''/''+@FileName'
SET @ParmDefinition = N'@RETURN VARCHAR(500) OUTPUT'
exec sp_executesql @sql, @ParmDefinition, @RETURN OUTPUT
set @RETURN=(select @RETURN)
RETURN @RETURN
END
但是当我执行这个功能时
select dbo.getContentURL(177,1)
这给出了错误:
The name 'select --------------------' is not a valid identifier.
如何返回这个执行值?有人能帮帮我吗?
