SqlServer查看各个表所占空间大小的sql

CREATE TABLE [dbo].#tableinfo(
表名 [varchar](50) COLLATE Chinese_PRC_CI_AS NULL,
记录数 [int] NULL,
预留空间 [varchar](50) COLLATE Chinese_PRC_CI_AS NULL,
使用空间 [varchar](50) COLLATE Chinese_PRC_CI_AS NULL,
索引占用空间 [varchar](50) COLLATE Chinese_PRC_CI_AS NULL,
未用空间 [varchar](50) COLLATE Chinese_PRC_CI_AS NULL
)

insert into #tableinfo(表名, 记录数, 预留空间, 使用空间, 索引占用空间, 未用空间)
exec sp_MSforeachtable "exec sp_spaceused '?'"

select * from #tableinfo
order by 记录数 desc

drop table #tableinfo

　　

另外一种方法：

create table #Data(name varchar(100),row varchar(100),reserved varchar(100),data varchar(100),index_size varchar(100),unused varchar(100)) 

declare @name varchar(100)
declare cur cursor  for
    select name from sysobjects where xtype='u' order by name
open cur
fetch next from cur into @name
while @@fetch_status=0
begin
    insert into #data
    exec sp_spaceused   @name
    print @name 

    fetch next from cur into @name
end
close cur
deallocate cur 

create table #DataNew(name varchar(100),row int,reserved int,data int,index_size int,unused int) 

insert into #dataNew
select name,convert(int,row) as row,convert(int,replace(reserved,'KB','')) as reserved,convert(int,replace(data,'KB','')) as data,
convert(int,replace(index_size,'KB','')) as index_size,convert(int,replace(unused,'KB','')) as unused from #data  

select * from #dataNew order by data desc

drop table  #Data
drop table #dataNew
