关于查询表结构
-- 查询非系统数据库 Select name FROM Master.. SysDatabases where dbid>4 -- 选择water数据库下的所有表 use [water] SELECT name FROM sysobjects WHERE xtype = 'U' Or xtype = 'S' -- 选择water数据库下的所有用户表 use [water] SELECT name FROM sysobjects WHERE xtype = 'U' AND OBJECTPROPERTY (id, 'IsMSShipped') = 0 -- 查询water数据库下的admin表的字段名,长度,类型,字段说明 use [water] SELECT a.[name] as '字段名',a.length '长度',c.[name] '类型',e.value as '字段说明' FROM syscolumns a left join systypes b on a.xusertype=b.xusertype left join systypes c on a.xtype = c.xusertype inner join sysobjects d on a.id=d.id and d.xtype='U' left join sys.extended_properties e on a.id = e.major_id and a.colid = e.minor_id and e.name='MS_Description' where d.name='admin'sys.extended_properties系统内置视图用于存储字段说明。
查询某张表的字段信息的话还可用如下方法:
select * from information_schema.columns where table_name ='colocal'
