Question

在SQL Server 2008中有没有办法生成一个报告，说明每个表占用多少磁盘空间？

我可以通过检查存储属性逐个完成，但我想知道是否有办法，甚至是查询来生成这样的报告。

Answer 1

是的，使用sp_spaceused存储过程来获取此信息......

USE AdventureWorks;
GO
EXEC sp_spaceused N'Purchasing.Vendor';
GO

结果将如下所示：

name    rows    reserved    data    index_size  unused
Vendor  104         48 KB   16 KB   32 KB   0 KB

要获取数据库使用中所有表的统计信息：

EXEC sp_MSforeachtable @command1="EXEC sp_spaceused '?'"

Answer 2

除了@kzen's correct answer之外，要获得可排序的单个结果集，请使用以下内容：

declare @t table (name sysname,rows int,reserved nvarchar(40),data nvarchar(50),index_size nvarchar(50),unused nvarchar(50))
INSERT INTO @T
EXEC sp_MSforeachtable @command1="EXEC sp_spaceused '?'"

--order by reserved space
select * from @t
order by CONVERT(int,LEFT(reserved,CHARINDEX(' ',reserved))) DESC

Answer 3

我同意推荐的解决方案，但添加了总计查询。最终得到的查询是：

    Use [DatabaseName]        

    declare @t table 
    (name sysname,rows int,reserved nvarchar(40),data nvarchar(50),index_size nvarchar(50),unused nvarchar(50)) 

    INSERT INTO @T 
        EXEC sp_MSforeachtable @command1="EXEC sp_spaceused '?'"

    --order by reserved space 
     select * from @t Order By [Name] -- order by CONVERT(int,LEFT(reserved,CHARINDEX(' ',reserved))) DESC 

    SELECT 
         Cast(Sum(Cast(Replace(reserved,' KB','') as int)) as varchar(12)) + ' KB' as Total_Reserved,
         Cast(Sum(Cast(Replace(data,' KB','') as int)) as varchar(12)) + ' KB' as Total_Data,
         Cast(Sum(Cast(Replace(index_size,' KB','') as int)) as varchar(12)) + ' KB' as Total_Index_Size,
         Cast(Sum(Cast(Replace(unused,' KB','') as int)) as varchar(12)) + ' KB' as Total_Unused
    FROM @T

在SQL Server 2008中有一种方法可以生成一个报告，告知每个表占用多少磁盘空间？
