如果需要查询表结构，SQL语句能否实现呢？下面就将为您介绍查询表结构的SQL语句的写法，希望对您学习SQL语句能够有所帮助。
- -- 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'
