(4.1)将表大小占用情况存放到新创建的 tablespaceinfo表中
if not exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[tablespaceinfo]') 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 from tablespaceinfo --清空数据表 declare @tablename varchar(255) --表名称 declare @cmdsql varchar(500) DECLARE Info_cursor CURSOR FOR select o.name from dbo.sysobjects o where OBJECTPROPERTY(o.id, N'IsTable') = 1 and o.name not like N'#%%' order by o.name OPEN Info_cursor FETCH NEXT FROM Info_cursor INTO @tablename WHILE @@FETCH_STATUS = 0 BEGIN if exists (select * from dbo.sysobjects where id = object_id(@tablename) 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 FROM Info_cursor INTO @tablename END CLOSE Info_cursor DEALLOCATE Info_cursor GO据说:
sp_spaceused的结果有时是不准确的, 要加updateusage选项才行,修改版:

--itlearner注:显示数据库信息 sp_spaceused @updateusage = 'TRUE'(4.3)查看存放了当前数据库各个表大小的tablespaceinfo表中记录
--itlearner注:显示表信息 select * from tablespaceinfo order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc
