获得SQL数据库信息的代码

复制代码 代码如下:

select name from master..sysdatabases order by name –获得所有数据库

select name from [数据库名]..sysobjects where xtype=’u’ order by name –获得数据库下的所有表

select name from syscolumns where id=object_id(n’表名’) –获得表里的所有字段

–获取表字段名、类型、递增、描述


复制代码 代码如下:

select syscolumns.name as 字段,syscolumns.isnullable as 可否为空,systypes.name as sql类型,

isnull(sys.identity_columns.is_identity,0) as 递增,

isnull(sys.extended_properties.value,”) as 描述 from sysobjects

join syscolumns on sysobjects.id = syscolumns.id

join systypes on syscolumns.xusertype = systypes.xusertype

left join sys.identity_columns on sys.identity_columns.object_id = syscolumns.id

and sys.identity_columns.column_id = syscolumns.colid

left join sys.extended_properties on sys.extended_properties.major_id = syscolumns.id

and sys.extended_properties.minor_id = syscolumns.colid

where sysobjects.name = ‘表名’
