SQL Server 2005 - 如何找出特定索引的磁盤大小

Question

如何找到sql server 2005中特定索引的磁盤大小？

Answer 1

USE master 

SELECT SUM(used_page_count) * 8 AS [Size in kb] 
FROM sys.indexes i 
JOIN sys.dm_db_partition_stats p ON p.object_id = i.object_id AND i.index_id = p.index_id 
WHERE i.object_id=OBJECT_ID('dbo.spt_values') AND i.name='ix2_spt_values_nu_nc' 

Answer 2

您可以使用存儲過程「sp_spaceused」。它會告訴你有多少空間用於索引以及用於數據的空間。

USE AdventureWorks2012; 
GO 
EXEC sp_spaceused 'Purchasing.Vendor'; 
GO

Find out the disk size of an index：

SELECT 
    OBJECT_NAME(I.OBJECT_ID) AS TableName, 
    I.name AS IndexName, 
    8 * SUM(AU.used_pages) AS 'Index size (KB)', 
    CAST(8 * SUM(AU.used_pages)/1024.0 AS DECIMAL(18,2)) AS 'Index size (MB)' 
FROM 
    sys.indexes I 
    JOIN sys.partitions P ON P.OBJECT_ID = I.OBJECT_ID AND P.index_id = I.index_id 
    JOIN sys.allocation_units AU ON AU.container_id = P.partition_id 
WHERE 
    OBJECT_NAME(I.OBJECT_ID) = '<TableName>'  
GROUP BY 
    I.OBJECT_ID,  
    I.name 
ORDER BY 
    TableName
