获取数据库中所有表的大小

Question

我继承了一个相当大的SQL Server数据库。考虑到它包含的数据，它似乎占用了比我预期更多的空间。

是否有一种简单的方法可以确定每个表占用的磁盘空间大小？

Answer 1

SELECT 
    t.NAME AS TableName,
    s.Name AS SchemaName,
    p.rows AS RowCounts,
    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 
    t.Name

Answer 2

如果您使用的是 SQL Server Management Studio （SSMS），而不是运行查询（，在我的情况下返回重复的行），您可以运行标准报告。

1. 右键单击数据库
2. 导航至报告＆gt;标准报告＆gt;表格中的磁盘使用情况

注意：必须将数据库兼容级别设置为90或更高才能使其正常工作。见http://msdn.microsoft.com/en-gb/library/bb510680.aspx

Answer 3

sp_spaceused可以获取有关表，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

报告ContactInfo表的磁盘使用信息。

一次性将它用于所有表格：

USE MyDatabase; GO

sp_msforeachtable 'EXEC sp_spaceused [?]' GO

您还可以从右键单击SQL Server的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Databases对象，然后右键单击任何数据库。从显示的菜单中，选择“报告”，然后选择“标准报告”，然后选择“按分区的磁盘使用情况：[DatabaseName]”。

Answer 4

以下是另一种方法：使用 SQL Server Management Studio ，在对象资源管理器中，转到您的数据库并选择表

然后打开对象资源管理器详细信息（通过按 F7 或转到 View-＆gt;对象资源管理器详细信息）。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。

Answer 5

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的便捷存储过程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。

以下脚本将生成我正在寻找的信息。

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

Answer 6

 exec  sp_spaceused N'dbo.MyTable'

对于所有表格，请使用..（从保罗的评论中添加）

exec sp_MSForEachTable 'exec sp_spaceused [?]'

Answer 7

上面的查询很适合查找表使用的空间量（包括索引），但是如果要比较表上索引使用的空间量，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

Answer 8

如果您需要计算SSMS中“表属性 - 存储”页面上完全相同的数字，则需要使用与SSMS中相同的方法对它们进行计数（适用于sql server 2005及更高版本。 。并且对于具有LOB字段的表也能正常工作 - 因为只计算“used_pa​​ges”不应该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

Answer 9

我们使用表分区，由于重复记录，上面提供的查询有些问题。

对于那些需要这个的人，您可以在SQL Server 2014运行的查询下面找到按表格生成＆＃34;磁盘使用情况＆＃34;报告。我认为它也适用于以前版本的SQL Server。

它就像一个魅力。

扩展到@xav answer处理表分区以获得MB和GB的大小。 在SQL Server 2008/2012上进行了测试（在is_memory_optimized = 1）

Mar_c的回答有一个小小的改动，因为我经常回到这个页面，大多数是第一行的命令：

SELECT
    t.NAME AS TableName,
    s.Name AS SchemaName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB,

    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB

Answer 14

要获取一个数据库中的所有表大小，您可以使用此查询：

Exec sys.sp_MSforeachtable ' sp_spaceused "?" '

您可以更改它以将所有结果插入到临时表中，然后从临时表中选择。

Insert into #TempTable Exec sys.sp_MSforeachtable ' sp_spaceused "?" ' 
Select * from #TempTable

Answer 15

使用OSQL从命令提示符输入：

OSQL -E -d <*databasename*> -Q "exec sp_msforeachtable 'sp_spaceused [?]'" > result.txt

Answer 16

以下是通过以下步骤快速获取所有表格大小的方法：

1. 编写给定的 T-SQL命令以列出所有数据库表：

   select 'exec sp_spaceused ' + TABLE_NAME from INFORMATION_SCHEMA.TABLES where TABLE_TYPE = 'BASE TABLE'
   

2. 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

   exec sp_spaceused table1
   exec sp_spaceused table2
   exec sp_spaceused table3
   exec sp_spaceused table4
   exec sp_spaceused table5
   

3. 在SQL 查询分析器中，从顶部工具栏选项中选择结果到文件（ Ctrl + Shift + F ）。

4. 现在最后点击上面工具栏标记的执行按钮红色。

5. 数据库所有表格的大小现在存储在您计算机上的文件中。

Answer 19

我的帖子仅与SQL Server 2000相关，并且经过测试可在我的环境中使用。

此代码访问单个实例的所有可能数据库，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“实时”表中。

返回的数据是：DatabaseName，DatabaseTableName，Rows（在表中），数据（表中KB的大小），条目数据（我发现这对于了解我上次运行脚本的时间非常有用）。

此代码的垮掉是'data'字段没有存储为int（字符'KB'保存在该字段中），这对于排序很有用（但不是完全必要的）。

希望这段代码可以帮助那些人并节省一些时间！

Answer 20

如果您只关心数据库中的空白空间而不是单个表，则可以考虑以下内容：

如果数据库经历了大量的数据插入然后删除的操作（例如在ETL情况下），这将导致数据库中文件组自动增长，但是从不自动扩展，从而导致数据库中的未使用空间过多-收缩。

通过使用数据库的属性页面，可以查看是否是这种情况。您可以缩小（右键单击数据库>任务>缩小）并收回一些空间。但是，如果根本原因仍然存在，数据库将重新增长（并花费额外的时间尝试重新增长，并且事情变慢，直到增长足够，因此在这种情况下不要这样做）

Answer 21

当前接受的答案具有2600多个投票，但在使用多个分区和/或过滤索引时会给出错误结果。它还不能区分数据大小和索引大小，这通常是非常相关的。一些建议的修复程序无法解决核心问题，或者根本就是错误的。

重复上面的@Mark回答，添加了@ updateusage ='true'来强制使用最新尺寸统计信息（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

这是一个示例查询，用于获取按大小降序排列的大于1GB的表。

USE YourDB
GO

DECLARE @Mult float = 8
SET @Mult = @Mult / POWER(2, 20) -- Use POWER(2, 10) for MBs

; WITH CTE AS
(
SELECT
    i.object_id,
    Rows = MAX(p.rows),
    TotalSpaceGB = ROUND(SUM(a.total_pages) * @Mult, 0),
    UsedSpaceGB = ROUND(SUM(a.used_pages) * @Mult, 0)
FROM 
    sys.indexes i
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
WHERE
    i.object_id > 255
GROUP BY
    i.object_id
HAVING
    SUM(a.total_pages) * @Mult > 1
)
SELECT 
    SchemaName = s.name,
    TableName = t.name,
    c.TotalSpaceGB,
    c.UsedSpaceGB,
    UnusedSpaceGB = c.TotalSpaceGB - c.UsedSpaceGB,
    [RowCount] = c.Rows
FROM 
    CTE c
JOIN    
    sys.tables t ON t.object_id = c.object_id
JOIN
    sys.schemas s ON t.schema_id = s.schema_id
ORDER BY
    c.TotalSpaceGB DESC

对于Azure，我使用了以下方法：

您应该拥有SSMS v17.x

我曾经用过

以此作为用户Sparrow has mentioned：

打开您的Databases>并选择表格，
然后按 F7 键 您应该看到row count
为：

SSMS 此处已连接到Azure数据库

我发现此查询易于使用且快速。

select schema_name(tab.schema_id) + '.' + tab.name as [table], 
cast(sum(spc.used_pages * 8)/1024.00 as numeric(36, 2)) as used_mb,
cast(sum(spc.total_pages * 8)/1024.00 as numeric(36, 2)) as allocated_mb
from sys.tables (nolock) tab
inner join sys.indexes (nolock) ind 
    on tab.object_id = ind.object_id
inner join sys.partitions  (nolock) part 
    on ind.object_id = part.object_id and ind.index_id = part.index_id
inner join sys.allocation_units (nolock) spc
    on part.partition_id = spc.container_id
group by schema_name(tab.schema_id) + '.' + tab.name
order by sum(spc.used_pages) desc
