已在堆栈溢出中得到解答:

链接到@Nelson并由@Nelson复制的查询是不准确的:它忽略索引视图,全文索引,XML索引等。
如果您希望查询包含不执行sp_spaceused
via的所有内容的查询sp_MSForEachTable
,那么我已经发布了它的两个变体(一个在DBA.StackExchange上,另一个在StackOverflow上),所以我不会在这里复制它们:
只是为了好玩,这是一个查询,它将生成与nateirvin的答案中的报告相同的数据
create table #disk_usage
(
name varchar(128)
,rows varchar(20)
,reserved varchar(20)
,data varchar(20)
,index_size varchar(20)
,unused varchar(20)
);
exec sp_msforeachtable 'insert into #disk_usage exec sp_spaceused [?]'
select SCHEMA_NAME(st.schema_id) + '.' + du.name 'Table Name'
,du.rows '# Records'
,du.reserved 'Reserved (KB)'
,du.data 'Data (KB)'
,du.index_size 'Indexes (KB)'
,du.unused 'Unused (KB)'
from #disk_usage du
left join sys.tables st
on du.name = st.name
order by cast(left(reserved, len(reserved) - 3) as bigint) desc;
drop table #disk_usage
好的,因为我真的很讨厌自己,所以我编写了一个查询,该查询将生成报告的结果,将其格式化为HTML表格,然后将其作为电子邮件发送。匹配报告背景颜色作为练习留给读者。
