SQL Server’da bazı durumlarda veritabanındaki en büyük tabloları ve Index’leri listelemek isteyebilirsiniz.

Aşağıdaki kodu kullanarak sizler de bu işlemi rahatlıkla yapabilirsiniz.

En Büyük Tabloları Listelemek

SELECT TOP 100
	s.[name] AS [schema]
   ,t.[name] AS [table_name]
   ,p.[rows] AS [row_count]
   ,CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS [size_mb]
   ,CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS [used_mb]
   ,CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS [unused_mb]
FROM sys.tables t
JOIN sys.indexes i
	ON t.[object_id] = i.[object_id]
JOIN sys.partitions p
	ON i.[object_id] = p.[object_id]
		AND i.index_id = p.index_id
JOIN sys.allocation_units a
	ON p.[partition_id] = a.container_id
LEFT JOIN sys.schemas s
	ON t.[schema_id] = s.[schema_id]
WHERE t.is_ms_shipped = 0
AND i.[object_id] > 255
GROUP BY t.[name]
		,s.[name]
		,p.[rows]
ORDER BY [size_mb] DESC

En Büyük Index’leri Listelemek

SELECT TOP(100)
    s.[name] AS [schema],
    t.[name] AS [table_name],
    i.[name] AS [index_name],
    i.[type_desc],
    p.[rows] AS [row_count],
    CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS [size_mb],
    CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS [used_mb], 
    CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS [unused_mb]
FROM
    sys.tables t
    JOIN sys.indexes i ON t.[object_id] = i.[object_id]
    JOIN sys.partitions p ON i.[object_id] = p.[object_id] AND i.index_id = p.index_id
    JOIN sys.allocation_units a ON p.[partition_id] = a.container_id
    LEFT JOIN sys.schemas s ON t.[schema_id] = s.[schema_id]
WHERE 
    t.is_ms_shipped = 0
    AND i.[object_id] > 255 
GROUP BY
    t.[name], 
    s.[name],
    i.[name],
    i.[type_desc],
    p.[rows]
ORDER BY 
    [size_mb] DESC
