如何取得一个数据库中所有的表的大小

一直使用以下的SQL

SET NOCOUNT ON

-- Table row counts and sizes.

CREATE TABLE #t

(

[name] NVARCHAR(128),

[rows] CHAR(11),

reserved VARCHAR(18),

data VARCHAR(18),

index_size VARCHAR(18),

unused VARCHAR(18)

)

INSERT #t EXEC sp_msForEachTable 'EXEC sp_spaceused ''?'''

-- Order by size (need to remove the KB sign).

SELECT *

FROM #t ORDER by cast(SUBSTRING(reserved, 1, LEN(reserved)-2) as Int) desc

DROP TABLE #t

但是今天碰到table名中含有schemas,就看上去怪怪的，

只好改用下面的SQL,还来不及检查发生了什么事，只好头痛医头脚痛医脚

declare @RowCount int, @tablename varchar(100)

declare @Tables table (

PK int IDENTITY(1,1),

tablename varchar(100),

processed bit

)

INSERT into @Tables (tablename)

SELECT '['+SCHEMA_NAME(schema_id)+'].['+name+']' AS TableName

FROM sys.tables order by TABLENAME asc

declare @Space table (

[id] [int] IDENTITY(1,1) NOT NULL,

name varchar(100), rows nvarchar(100), reserved varchar(100), data char(100), index_size varchar(100), unused varchar(100)

)

select top 1 @tablename = tablename from @Tables where processed is null

SET @RowCount = 1

WHILE (@RowCount <> 0)

BEGIN

print @tablename

insert into @Space exec sp_spaceused @tablename

update @Space set name = @tablename where id = (select top 1 MAX(id) as no from @Space)

update @Tables set processed = 1 where tablename = @tablename

select top 1 @tablename = tablename from @Tables where processed is null

SET @RowCount = @@RowCount

END

update @Space set data = replace(data, 'KB', '')

update @Space set data = cast(data as decimal(10,0)) / 1000

update @Space set data = cast(data as decimal(10,2))

update @Space set reserved = replace(reserved, 'KB', '')

update @Space set reserved = cast(reserved as decimal(10,0)) / 1000

update @Space set reserved = cast(reserved as decimal(10,2))

select name as Tablename, rows, replace(data,' ','') + 'MB' as used, replace(reserved,' ','') + 'MB' as [Reserved] ,index_size,unused from @Space order by convert(decimal(10,2),data) desc
