获取表和索引存储大小在SQL Server中

我想为我的数据库中的每个表获取表数据和索引空间：

Table Name Data Space Index Space ------------------------------------------------------- 

我怎样才能达到这个结果？

Answer 1

此处的查询将列出表占用的总大小 – 聚簇索引，堆和所有非聚簇索引：

 SELECT s.Name AS SchemaName, t.NAME AS TableName, p.rows AS RowCounts, SUM(a.total_pages) * 8 AS TotalSpaceKB, SUM(a.used_pages) * 8 AS UsedSpaceKB, (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB FROM sys.tables t INNER JOIN sys.schemas s ON s.schema_id = t.schema_id INNER JOIN sys.indexes i ON t.OBJECT_ID = i.object_id INNER JOIN sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id INNER JOIN sys.allocation_units a ON p.partition_id = a.container_id WHERE t.NAME NOT LIKE 'dt%' -- filter out system tables for diagramming AND t.is_ms_shipped = 0 AND i.OBJECT_ID > 255 GROUP BY t.Name, s.Name, p.Rows ORDER BY s.Name, t.Name 

如果要从索引空间中分离表空间，则需要对表空间使用AND i.index_id IN (0,1) （ index_id = 0是堆空间， index_id = 1是聚簇索引的大小= data页面） AND i.index_id > 1为索引唯一的空间

 with pages as ( SELECT object_id, SUM (reserved_page_count) as reserved_pages, SUM (used_page_count) as used_pages, SUM (case when (index_id < 2) then (in_row_data_page_count + lob_used_page_count + row_overflow_used_page_count) else lob_used_page_count + row_overflow_used_page_count end) as pages FROM sys.dm_db_partition_stats group by object_id ), extra as ( SELECT p.object_id, sum(reserved_page_count) as reserved_pages, sum(used_page_count) as used_pages FROM sys.dm_db_partition_stats p, sys.internal_tables it WHERE it.internal_type IN (202,204,211,212,213,214,215,216) AND p.object_id = it.object_id group by p.object_id ) SELECT object_schema_name(p.object_id) + '.' + object_name(p.object_id) as TableName, (p.reserved_pages + isnull(e.reserved_pages, 0)) * 8 as reserved_kb, pages * 8 as data_kb, (CASE WHEN p.used_pages + isnull(e.used_pages, 0) > pages THEN (p.used_pages + isnull(e.used_pages, 0) - pages) ELSE 0 END) * 8 as index_kb, (CASE WHEN p.reserved_pages + isnull(e.reserved_pages, 0) > p.used_pages + isnull(e.used_pages, 0) THEN (p.reserved_pages + isnull(e.reserved_pages, 0) - p.used_pages + isnull(e.used_pages, 0)) else 0 end) * 8 as unused_kb from pages p left outer join extra e on p.object_id = e.object_id 

考虑内部表，例如用于XML存储的表。

编辑：如果你将data_kb和index_kb值除以1024.0，你将得到你在GUI中看到的数字。
