SQL Server查看所有表大小、表行数和占用空间信息

一、查看表名和对应的数据行数

select  a.name as '表名',b.rows as '表数据行数'
from sysobjects a inner join sysindexes b
on a.id = b.id
where   a.type = 'u'
and b.indid in (0,1)
--and a.name not like 't%'
order by b.rows desc

二、查看表名和表占用空间信息
--判断临时表是否存在，存在则删除重建
if exists(select 1 from tempdb..sysobjects where id=object_id('tempdb..#tabName') and xtype='u')
drop table #tabName
go
create table #tabName(
tabname varchar(100),
rowsNum varchar(100),
reserved varchar(100),
data varchar(100),
index_size varchar(100),
unused_size 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 #tabName
    exec sp_spaceused @name
    --print @name
 
    fetch next from cur into @name
end
close cur
deallocate cur

select tabname as '表名',rowsNum as '表数据行数',reserved as '保留大小',data as '数据大小',index_size as '索引大小',unused_size as '未使用大小'
from #tabName
--where tabName not like 't%'
order by cast(rowsNum as int) desc

--系统存储过程说明：

--sp_spaceused 该存储过程在系统数据库master下。
exec sp_spaceused '表名' --该表占用空间信息
exec sp_spaceused           --当前数据库占用空间信息
