【S】SQL SERVER检查临时表占用空间情况

--检查已标记为需要删除的临时表
select * from
T_BAS_TEMPORARYTABLENAME;

--所有系统创建的临时表及视图
SELECT * FROM sys.tables
WHERE name LIKE 'TMP%'

-- 查看系统所有表占用的空间情况
create table tmpspace
(Fname varchar(50),
Frows int,
Freserved varchar(50),
  Fdata
varchar(50),
  Findex_size varchar(50),
  Funused
varchar(50));
 
insert into tmpspace
(Fname,Frows,Freserved,  Fdata,Findex_size,Funused)
exec sp_msforeachTable
@Command1="sp_spaceused '?'"

select * from tmpspace where Fname like
'TMP%' order by Fdata desc

--临时表占用的总大小（M）
select
SUM(CONVERT(DECIMAL,replace(fdata,'KB','')))/1024 M from tmpspace where Fname
like 'TMP%';
--drop table tmpspace;

--删除所有已经标记为需要删除的临时表
