SQL查询某数据库各表占用磁盘空间和收缩数据库MDF文件

--查数据库中多数表占用的空间

CREATE TABLE TMP 
(name varchar(50),
rows int,
reserved varchar(50),
data varchar(50),
index_size varchar(50),
unused varchar(50))
GO

INSERT INTO tmp (name,rows,reserved,data,index_size,unused) 
EXEC sp_msforeachTable @Command1="sp_spaceused '?'"
SELECT *,CONVERT(int, replace(data,' KB','')) as tt FROM tmp ORDER BY tt DESC 
DROP TABLE tmp


GO


--收缩可让数据库大小减小很多特别是MDF文件
ALTER DATABASE DBname 
Set  RECOVERY SIMPLE 
Go 

DBCC SHRINKDATABASE  (DBname) 
Go 

ALTER DATABASE DBname 
Set  RECOVERY  FULL 
Go
