点评：本文主要介绍了sql查看所有表大小的方法,感兴趣的朋友可以参考一下，希望对大家有所帮助！

复制代码 代码如下:

declare @id            int

declare @type          character(2)                 

declare @pages         int                        

declare @dbname        sysname

declare @dbsize        dec(15,0)

declare @bytesperpage dec(15,0)

declare @pagesperMB    dec(15,0)

create table #spt_space

    [objid]         int null,

    [rows]          int null,

    [reserved]      dec(15) null,

    [data]          dec(15) null,

    [indexp]        dec(15) null,

    [unused]        dec(15) null

)

set nocount on
