復(fù)制代碼 代碼如下:
SELECT Name FROM Master..SysDatabases ORDER BY Name --獲得所有數(shù)據(jù)庫(kù)
SELECT Name FROM [數(shù)據(jù)庫(kù)名]..SysObjects Where XType='U' ORDER BY Name --獲得數(shù)據(jù)庫(kù)下的所有表
select name from syscolumns where id=object_id(N'表名') --獲得表里的所有字段
--獲取表字段名、類型、遞增、描述
復(fù)制代碼 代碼如下:
select syscolumns.name as 字段,syscolumns.isnullable as 可否為空,systypes.name as SQL類型,
ISNULL(sys.identity_columns.is_identity,0) as 遞增,
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'
