how to get the space size of some tables in one database?

如何获取SQLServer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'


step1：先写一个存储过程，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

CREATEPROCEDUREget_tableinfoAS

ifnotexists(select*fromdbo.sysobjectswhereid=object_id(N'[dbo].[tablespaceinfo]')andOBJECTPROPERTY(id,N'IsUserTable')=1)
createtabletablespaceinfo--创建结果存储表
(nameinfovarchar(50),
rowsinfoint,reservedvarchar(20),
datainfovarchar(20),
index_sizevarchar(20),
unusedvarchar(20))


deletefromtablespaceinfo--清空数据表

declare@tablenamevarchar(255)--表名称

declare@cmdsqlvarchar(500)

DECLAREInfo_cursorCURSORFOR
selecto.name
fromdbo.sysobjectsowhereOBJECTPROPERTY(o.id,N'IsTable')=1
ando.namenotlikeN'#%%'orderbyo.name

OPENInfo_cursor

FETCHNEXTFROMInfo_cursor
INTO@tablename

WHILE@@FETCH_STATUS=0
BEGIN

ifexists(select*fromdbo.sysobjectswhereid=object_id(@tablename)andOBJECTPROPERTY(id,N'IsUserTable')=1)
executesp_executesql
N'insertintotablespaceinfoexecsp_spaceused@tbname',
N'@tbnamevarchar(255)',
@tbname=@tablename

FETCHNEXTFROMInfo_cursor
INTO@tablename
END

CLOSEInfo_cursor
DEALLOCATEInfo_cursor
GO


step2：执行存储过程
execget_tableinfo

查询运行该存储过程后得到的结果
select*
fromtablespaceinfo
orderbycast(left(ltrim(rtrim(reserved)),len(ltrim(rtrim(reserved)))-2)asint)desc
