最近又忘记存储过程 除了exec 动态写法的另外一种,这里记录一下,方便查找
写法1,动态语句
CREATE PROCEDURE sp_CountShiftWish
@strids varchar () /*strids 是id列表， 类似1,2,3*/
AS
exec ('select * from student where id in('+@strids+')') go
写法2,索引查找
CREATE PROCEDURE sp_CountShiftWish
@strids varchar () /*strids 是id列表， 类似1,2,3*/
AS
select * from student where charindex(','+ltrim(id)+',',','+@strids+',')>
go
