SQL计算数据库表占用的真实空间大小

   最近客户的数据库暴涨,一开始找不到原因,用sql查询表的空间大小,结果之前用的sql语句只能查询除了text,image外的字段大小.搞得一时间混乱不堪.后来咨询了大师们,找到用sp_spaceused这个系统函数可以查询表的真实大小,包含text等字段.sql如下:

?

declare @id            NVARCHAR(100)

create table #spt_space

(

    [name]            NVARCHAR(50) null,

    [rows]          int null,

    [reserved]       NVARCHAR(50) null,

    [data]         NVARCHAR(50) null,

    [index_size]        NVARCHAR(50) null,

    [unused]         NVARCHAR(50) null

)

 

set nocount on

 

declare c_tables cursor for

select name from sysobjects where xtype = 'U'

 

open c_tables fetch next from c_tables into @id

 

while @@fetch_status = 0

begin

    /* Code from sp_spaceused */

    insert into #spt_space ([name],[rows],reserved,data,index_size,unused)

    EXEC sp_spaceused @id

    fetch next from c_tables   into @id

 

end

SELECT * FROM(

SELECT *,CAST(REPLACE(reserved,'KB','') AS INT) AS reservedindex FROM #spt_space

) c

order by c.reservedindex desc

 

drop table #spt_space

close c_tables

deallocate c_tables
