每当sql server中建存储过程。      CASE WHEN a.colorder = 1 THEN d.name ELSE ” END AS 表名。

于sql server中建存储过程,如果欲参数是一个可变集合的处理

当sql server中建存储过程,如果用参数是一个可变集合怎么处理?

上网搜了瞬间多数都是酱油贴,有网友说用xml的计,具体的代码也从没看见

 

亏本中时而,用sql拼接来实现而变换参数的机能 

先行选出个sql拼接的例证

DECLARE @sql NVARCHAR(MAX)

SET @sql =’select 1 mmd’

EXECUTE(@sql)

SET @sql =’SELECT c.Name,AVG(e.Score)
Score FROM dbo.Sys_com_comment_main m

         INNER JOIN
dbo.sys_com_category c ON e.NameKey=c.NameKey
