如何获取SQL Server数据库里表的占用容量大小

其实只要使用系统内置的存储过程sp_spaceused就可以得到表的相关信息
如：sp_spaceused @#tablename@#
以下是为了方便写的一个存储过程，目的是把当前的所有表的相关信息全部都保存在一个指定的表里面
CREATE PROCEDURE get_tableinfo AS

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


执行存储过程
exec get_tableinfo
查询运行该存储过程后得到的结果
select *
from tablespaceinfo
order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc
