-----执行删除多条的存储过程
CREATE PROCEDURE [dbo].[xxxxxxx]
@list VARCHAR (1000)
AS
delete from Table WHERE
CHARINDEX(','+trim(column)+',','+@list +',') > 0
SET @sql_All='select @count=count(*) from Table'
EXEC sp_executesql @sql_All,
N‘@cunt INT OUTPUT',
@count OUTPUT
----执行插入操作并将插入记录自增id返回
string sql = @"INSERT Table(a,b)Values('1','2') select @@identity";
object obj = ExecuteScalar(sql);
----一条记录行转列
select name=stuff(
(select '-'+name from student for xml path('')),1,'')
name是student表里的一个字段，格式如下：
name
张三
李四
王五
用一个sql语句输出以下格式：
张三-李四-王五
