MSSQL数据库每个表占用的空间、大小

方法一：

 1 if NOT EXISTS
 2     (SELECT *
 3     FROM dbo.sysobjects
 4     WHERE id = object_id(N‘[dbo].[tablespaceinfo]‘)
 5             AND OBJECTPROPERTY(id, N‘IsUserTable‘) = 1) create table tablespaceinfo --创建结果存储表 (nameinfo varchar(50) , rowsinfo int , reserved varchar(20) , datainfo varchar(20) , index_size varchar(20) , unused varchar(20) ) delete
 6 FROM tablespaceinfo --清空数据表 declare @tablename varchar(255) --表名称 declare @cmdsql varchar(500) DECLARE Info_cursor CURSOR FORSELECT o.name
 7 FROM dbo.sysobjects o
 8 WHERE OBJECTPROPERTY(o.id, N‘IsTable‘) = 1
 9         AND o.name NOT LIKE N‘#%%‘
10 ORDER BY  o.name OPEN Info_cursor FETCH NEXT
11 FROM Info_cursor INTO @tablename WHILE @@FETCH_STATUS = 0 BEGIN if EXISTS
12     (SELECT *
13     FROM dbo.sysobjects
14     WHERE id = object_id(@tablename)
15             AND OBJECTPROPERTY(id, N‘IsUserTable‘) = 1) execute sp_executesql N‘insert into tablespaceinfo exec sp_spaceused @tbname‘, N‘@tbname varchar(255)‘, @tbname = @tablename FETCH NEXT
16 FROM Info_cursor INTO @tablename
17     END CLOSE Info_cursor DEALLOCATE Info_cursor GO --itlearner注：显示数据库信息 sp_spaceused @updateusage = ‘TRUE‘ --itlearner注：显示表信息SELECT *
18 FROM tablespaceinfo
19 ORDER BY  cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) AS int) DESC 

方法二：

1 SELECT object_name(id) tablename,
2         8*reserved/1024 reserved,
3         dpages,
4          rtrim(8*dpages/1024)+‘Mb‘ used,8*(reserved-dpages)/1024 unused, 8*dpages/1024-rows/1024*minlen/1024 free, rows,*
5 FROM sysindexes a
6 WHERE indid=1
7 ORDER BY  a.reserved DESC
