MSSQL基本常用笔记

--读取库中的所有表名

select name from sysobjects where xtype='u' order by name desc

--读取指定表的所有列名

 

select name from syscolumns where id=(select max(id) from sysobjects where xtype='u' and name='Member')

 

--查询数据库中所有的表名及行数

 

SELECT a.name, b.rows FROM sysobjects AS a INNER JOIN sysindexes AS b ON a.id = b.id WHERE (a.type = 'u') AND (b.indid IN (0, 1)) ORDER BY a.name,b.rows DESC

 

--查询所有的表名及空间占用量\行数

 

select object_name(id) tablename,8*reserved/1024 reserved,rtrim(8*dpages)+'kb' used,8*(reserved-dpages)/1024 unused,8*dpages/1024-rows/1024*minlen/1024 free,rows from sysindexes where indid=1 order by rows desc
