当SQLServer数据库越来越庞大，而其中的表有非常多的时候，想要知道到底是哪些表最耗存储空间，到底该怎样统计各个表的存储大小呢
其实SQLServer提供了一个sp_spaceused的系统存储过程可以实现该功能，下面就是调用的SQL：代码如下:
create table #tb(表名 sysname,记录数 int
,保留空间 varchar(10),使用空间 varchar(10)
,索引使用空间 varchar(10),未用空间 varchar(10))
insert into #tb exec sp_MSForEachTable 'EXEC sp_spaceused ''?'''
select * from #tb
go
drop table #tb
这样就可以枚举出每个表存储空间的详细使用情况！
