------解决方案--------------------
SQL code
3.获取当前数据库中的所有用户表
select * from sysobjects where xtype='U' and category=0
4.获取某一个表的所有字段
select name from syscolumns where id=object_id('表名')
--使用这两个语句嵌套查询
------解决方案--------------------
SQL code
--本机测试
select name from sysobjects where id in(
select id from syscolumns where id
in(select id from sysobjects where xtype='U' and category=0)
and name='费用名称')
/*
name
收费表
费用表
*/
------解决方案--------------------
SQL code
select o.name,c.name FROM syscolumns c JOIN sysobjects o ON c.id=o.id
-- 175=char 56=int 可以查 select * from sys.types
WHERE o.xtype='U' AND c.status>=0 AND c.xusertype IN (175, 239, 231, 167 )
and c.name like '%column_name%'
