2014-5-13-sql 查询指定表是否含有指定列

1.正常插入

if not exists(

select   1   from   syscolumns   where   id=object_id('source_wait')   and   name='sort'  )
begin
alter table source_wait add  sort  int not null default 0
end
go

2.标示插入

set IDENTITY_INSERT 表名 on
set IDENTITY_INSERT 表名 off

3.新增存储过程，首先判断存储过程是否存在
