我继承了一个相当大的SQL Server数据库。考虑到它包含的数据，它似乎比我预期的要占用更多的空间。
是否有一种简单的方法来确定每个表占用的磁盘空间？
SELECT
t.NAME AS TableName,
s.Name AS SchemaName,
p.rows,
SUM(a.total_pages) * 8 AS TotalSpaceKB,
CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceMB,
SUM(a.used_pages) * 8 AS UsedSpaceKB,
CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceMB,
(SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB,
CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceMB
FROM
sys.tables t
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
LEFT OUTER JOIN
sys.schemas s ON t.schema_id = s.schema_id
WHERE
t.NAME NOT LIKE 'dt%'
AND t.is_ms_shipped = 0
AND i.OBJECT_ID > 255
GROUP BY
t.Name, s.Name, p.Rows
ORDER BY
TotalSpaceMB DESC, t.Name
经过一番搜索，我找不到一种简单的方法来获取所有表格的信息。有一个名为sp_spaceused的方便存储过程，它将返回数据库使用的所有空间。如果提供了表名，则返回该表使用的空间。但是，存储过程返回的结果不可排序，因为列是字符值。
以下脚本将生成我要查找的信息。
create table #TableSize (
Name varchar(255),
[rows] int,
reserved varchar(255),
data varchar(255),
index_size varchar(255),
unused varchar(255))
create table #ConvertedSizes (
Name varchar(255),
[rows] int,
reservedKb int,
dataKb int,
reservedIndexSize int,
reservedUnused int)
EXEC sp_MSforeachtable @command1="insert into #TableSize
EXEC sp_spaceused '?'"
insert into #ConvertedSizes (Name, [rows], reservedKb, dataKb, reservedIndexSize, reservedUnused)
select name, [rows],
SUBSTRING(reserved, 0, LEN(reserved)-2),
SUBSTRING(data, 0, LEN(data)-2),
SUBSTRING(index_size, 0, LEN(index_size)-2),
SUBSTRING(unused, 0, LEN(unused)-2)
from #TableSize
select * from #ConvertedSizes
order by reservedKb desc
drop table #TableSize
drop table #ConvertedSizes
exec sp_spaceused N'dbo.MyTable'
对于所有表，请使用。。（根据保罗的评论补充）
exec sp_MSForEachTable 'exec sp_spaceused [?]'
这将为您提供每个表的大小和记录计数。

END
sp_spaceused可以获取表、索引视图或整个数据库使用的磁盘空间的信息。
例如：
USE MyDatabase; GO
EXEC sp_spaceused N'User.ContactInfo'; GO
这将报告ContactInfo表的磁盘使用情况信息。
要同时对所有表使用此选项：
USE MyDatabase; GO
sp_msforeachtable 'EXEC sp_spaceused [?]' GO
您还可以从SQL Server的右键单击“标准报告”功能中获取磁盘使用情况。要获取此报告，请从对象资源管理器中的服务器对象导航，向下移动到数据库对象，然后右键单击任何数据库。从出现的菜单中，选择“报告”，然后选择“标准报告”，再选择“磁盘分区使用情况：[DatabaseName]”。
我的文章只与SQL Server 2000相关，并且已经过测试，可以在我的环境中工作。
该代码访问单个实例的所有可能的数据库，而不仅仅是单个数据库。
我使用两个临时表来帮助收集适当的数据，然后将结果转储到一个“Live”表中。
返回的数据是：DatabaseName、DatabaseTableName、Rows（在表中）、data（表的大小，以KB为单位）、entry data（我发现这对了解我上次运行脚本的时间很有用）。
这段代码的缺点是“data”字段不是以int形式存储的（字符“KB”保留在该字段中），这对于排序是有用的（但不是完全必要的）。
希望这段代码能帮助一些人，并为他们节省一些时间！

如果您使用的是SQL Server Management Studio（SSMS），则可以运行标准报告，而不是运行查询（在我的情况下返回重复的行）
右键单击数据库导航到报告>标准报告>磁盘使用情况（按表）
注意：数据库兼容级别必须设置为90或更高，才能正常工作。看见http://msdn.microsoft.com/en-gb/library/bb510680.aspx
以上查询有助于查找表（包括索引）使用的空间量，但如果要比较表上的索引使用了多少空间，请使用以下查询：
SELECT
OBJECT_NAME(i.OBJECT_ID) AS TableName,
i.name AS IndexName,
i.index_id AS IndexID,
8 * SUM(a.used_pages) AS 'Indexsize(KB)'
FROM
sys.indexes AS i
JOIN sys.partitions AS p ON p.OBJECT_ID = i.OBJECT_ID AND p.index_id = i.index_id
JOIN sys.allocation_units AS a ON a.container_id = p.partition_id
WHERE
i.is_primary_key = 0 -- fix for size discrepancy
GROUP BY
i.OBJECT_ID,
i.index_id,
i.name
ORDER BY
OBJECT_NAME(i.OBJECT_ID),
i.index_id
我在marc_s答案的顶部添加了几列：
with fs
as
(
select i.object_id,
p.rows AS RowCounts,
SUM(a.total_pages) * 8 AS TotalSpaceKb
from sys.indexes i 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
i.OBJECT_ID > 255
GROUP BY
i.object_id,
p.rows
)
SELECT
t.NAME AS TableName,
fs.RowCounts,
fs.TotalSpaceKb,
t.create_date,
t.modify_date,
( select COUNT(1)
from sys.columns c
where c.object_id = t.object_id ) TotalColumns
FROM
sys.tables t INNER JOIN
fs ON t.OBJECT_ID = fs.object_id
WHERE
t.NAME NOT LIKE 'dt%'
AND t.is_ms_shipped = 0
ORDER BY
t.Name
-- Show the size of all the tables in a database sort by data size descending
SET NOCOUNT ON
DECLARE @TableInfo TABLE (tablename varchar(255), rowcounts int, reserved varchar(255), DATA varchar(255), index_size varchar(255), unused varchar(255))
DECLARE @cmd1 varchar(500)
SET @cmd1 = 'exec sp_spaceused ''?'''
INSERT INTO @TableInfo (tablename,rowcounts,reserved,DATA,index_size,unused)
EXEC sp_msforeachtable @command1=@cmd1
SELECT * FROM @TableInfo ORDER BY Convert(int,Replace(DATA,' KB','')) DESC
如果需要精确计算SSMS中“表财产-存储”页面上的相同数字，则需要使用与SSMS中相同的方法进行计数（适用于sql server 2005及更高版本……也适用于具有LOB字段的表，因为仅计算“used_pages”不足以显示准确的索引大小）：
;with cte as (
SELECT
t.name as TableName,
SUM (s.used_page_count) as used_pages_count,
SUM (CASE
WHEN (i.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 AS s
JOIN sys.tables AS t ON s.object_id = t.object_id
JOIN sys.indexes AS i ON i.[object_id] = t.[object_id] AND s.index_id = i.index_id
GROUP BY t.name
)
select
cte.TableName,
cast((cte.pages * 8.)/1024 as decimal(10,3)) as TableSizeInMB,
cast(((CASE WHEN cte.used_pages_count > cte.pages
THEN cte.used_pages_count - cte.pages
ELSE 0
END) * 8./1024) as decimal(10,3)) as IndexSizeInMB
from cte
order by 2 desc
从使用OSQL的命令提示符：
OSQL -E -d <*databasename*> -Q "exec sp_msforeachtable 'sp_spaceused [?]'" > result.txt
要获取一个数据库中的所有表大小，可以使用以下查询：
Exec sys.sp_MSforeachtable ' sp_spaceused "?" '
您可以将其更改为将所有结果插入临时表，然后从临时表中进行选择。
Insert into #TempTable Exec sys.sp_MSforeachtable ' sp_spaceused "?" '
Select * from #TempTable
在上面的@Mark回答中，添加了@updateusage='true'以强制更新最新的尺码统计(https://msdn.microsoft.com/en-us/library/ms188776.aspx):
SET NOCOUNT ON
DECLARE @TableInfo TABLE (tablename varchar(255), rowcounts int, reserved varchar(255), DATA varchar(255), index_size varchar(255), unused varchar(255))
DECLARE @cmd1 varchar(500)
SET @cmd1 = 'exec sp_spaceused @objname =''?'', @updateusage =''true'' '
INSERT INTO @TableInfo (tablename,rowcounts,reserved,DATA,index_size,unused)
EXEC sp_msforeachtable @command1=@cmd1
SELECT * FROM @TableInfo ORDER BY Convert(int,Replace(DATA,' KB','')) DESC
与Marc_s的回答有一点不同，因为我经常回到这一页，按大多数第一行排序：
SELECT
t.NAME AS TableName,
s.Name AS SchemaName,
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.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
LEFT OUTER JOIN
sys.schemas s ON t.schema_id = s.schema_id
WHERE
t.NAME NOT LIKE 'dt%'
AND t.is_ms_shipped = 0
AND i.OBJECT_ID > 255
GROUP BY
t.Name, s.Name, p.Rows
ORDER BY
--p.rows DESC --Uncomment to order by amount rows instead of size in KB.
SUM(a.total_pages) DESC
我们使用表分区，由于重复记录，上面提供的查询有一些问题。
对于需要此功能的人，您可以在下面找到SQL Server 2014在生成“磁盘使用情况（按表）”报告时运行的查询。我假设它也适用于以前版本的SQL Server。
它就像一个符咒。
SELECT
a2.name AS [tablename],
a1.rows as row_count,

(CASE WHEN (a1.reserved + ISNULL(a4.reserved,0)) > a1.used THEN (a1.reserved + ISNULL(a4.reserved,0)) - a1.used ELSE 0 END) * 8 AS unused
FROM
(SELECT
ps.object_id,
SUM (

) AS [rows],
SUM (ps.reserved_page_count) AS reserved,
SUM (
CASE
WHEN (ps.index_id < 2) THEN (ps.in_row_data_page_count + ps.lob_used_page_count + ps.row_overflow_used_page_count)

INNER JOIN sys.all_objects a2 ON ( a1.object_id = a2.object_id )
INNER JOIN sys.schemas a3 ON (a2.schema_id = a3.schema_id)
WHERE a2.type <> N'S' and a2.type <> N'IT'
ORDER BY a3.name, a2.name
以下是通过以下步骤快速获取所有表格大小的方法：
编写给定的T-SQL命令以列出所有数据库表：从INFORMATION_SCHEMA.TABLES中选择“exec sp_spaceused”+TABLE_NAME，其中TABLE_TYPE=“BASE TABLE”现在复制数据库表列表，并将其复制到新的查询分析器窗口中执行sp_spaceused表1执行sp_spaceused表2执行sp_spaceused表3执行sp_spaceused表4执行sp_spaceused表5在SQL查询分析器中，从顶部工具栏中选择“结果到文件”选项（Ctrl+Shift+F）。现在，最后点击上面工具栏中标记为红色的Execute按钮。所有表的数据库大小现在存储在计算机上的文件中。
作为marc_s答案（已被接受的答案）的一个简单扩展，它被调整为返回列计数并允许过滤：
SELECT *
FROM
(
SELECT
t.NAME AS TableName,
s.Name AS SchemaName,
p.rows AS RowCounts,
COUNT(DISTINCT c.COLUMN_NAME) as ColumnCount,
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.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
INNER JOIN
INFORMATION_SCHEMA.COLUMNS c ON t.NAME = c.TABLE_NAME
LEFT OUTER JOIN
sys.schemas s ON t.schema_id = s.schema_id
WHERE
t.NAME NOT LIKE 'dt%'
AND t.is_ms_shipped = 0
AND i.OBJECT_ID > 255
GROUP BY
t.Name, s.Name, p.Rows
) AS Result
WHERE
RowCounts > 1000
AND ColumnCount > 10
ORDER BY
UsedSpaceKB DESC
下面是另一种方法：使用SQLServerManagementStudio，在对象资源管理器中，转到数据库并选择表
然后打开“对象浏览器详细信息”（按F7或转到“查看”->“对象浏览器详情”）。在对象资源管理器详细信息页面中，右键单击列标题并启用您希望在页面中看到的列。您也可以按任何列对数据进行排序。

如果您只关心数据库中的空浪费空间，而不关心单个表，则可以考虑以下问题：
如果数据库经历了大量的数据插入和删除，可能与ETL情况类似，这将导致数据库中有太多未使用的空间，因为文件组会自动增长，但不会自动收缩。
您可以通过使用数据库的财产页面来查看是否是这种情况。您可以收缩（右键单击数据库>任务>收缩）并收回一些空间。但是，如果根本原因仍然存在，则数据库将增长（并花费额外的时间尝试增长，直到增长到足够的速度，所以不要这样做）
当处理多个分区和/或筛选索引时，Marc_s的答案给出了错误的结果。它也不区分数据和索引的大小，这通常是非常相关的。一些建议的修复方法并不能解决核心问题，或者根本就是错误的。
以下查询解决了所有这些问题。

我要感谢Greg Low先生的提问：
SELECT o.name AS ObjectName,
SUM(reserved_page_count) * 8.0 / 1024 AS SizeinMB
FROM sys.dm_db_partition_stats AS ps
INNER JOIN sys.sysobjects AS o
ON ps.object_id = o.id
GROUP BY o.name
ORDER BY SizeinMB DESC;
