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，它似乎占用的空间比我预期的要多。

有没有一种简单的方法可以确定每个表占用了多少磁盘空间？

Answer 1

CREATE TABLE #tmp_table_info
(
id int identity(1,1),
tblname varchar(200)
);
CREATE TABLE #SpaceUsed 
(
     TableName sysname
    ,NumRows BIGINT
    ,ReservedSpace VARCHAR(50)
    ,DataSpace VARCHAR(50)
    ,IndexSize VARCHAR(50)
    ,UnusedSpace VARCHAR(50)
) 

insert into #tmp_table_info
select s.name+'.'+t.name 
from sys.tables t 
inner join sys.schemas s on t.schema_id = s.schema_id
where t.type = 'U';

declare @min int =1,@max int = 0
select @max = count(*)
from #tmp_table_info
while(@min<=@max)
begin
    declare @tablename varchar(200)
    select @tablename=tblname
    from #tmp_table_info
    where id =@min

    DECLARE @str VARCHAR(500)
    SET @str =  'sp_spaceused '''+@tablename+''''
    INSERT INTO #SpaceUsed 
    EXEC (@str)  
    set @min =@min + 1
end;
select @@SERVERNAME as servername,DB_NAME() as DatabaseName,CONVERT(numeric(18,0),REPLACE(ReservedSpace,' KB','')) / 1024 as ReservedSpace_MB,
CONVERT(numeric(18,0),REPLACE(DataSpace,' KB','')) / 1024 as DataSpace_MB,
CONVERT(numeric(18,0),REPLACE(IndexSize,' KB','')) / 1024 as IndexSpace_MB,
CONVERT(numeric(18,0),REPLACE(UnusedSpace,' KB','')) / 1024 as UnusedSpace_MB from #SpaceUsed
drop table #tmp_table_info
drop table #SpaceUsed

Answer 2

当前接受的答案有超过 2600 个赞成票，但在使用多个分区和/或过滤索引时会给出不正确的结果。它也不区分数据和索引的大小，这通常非常相关。一些建议的修复没有解决核心问题，或者根本就是错误的。

以下查询解决了所有这些问题。

SELECT 
     [object_id]        = t.[object_id]
    ,[schema_name]      = s.[name]
    ,[table_name]       = t.[name]
    ,[index_name]       = CASE WHEN i.[type] in (0,1,5) THEN null    ELSE i.[name] END -- 0=Heap; 1=Clustered; 5=Clustered Columnstore
    ,[object_type]      = CASE WHEN i.[type] in (0,1,5) THEN 'TABLE' ELSE 'INDEX'  END
    ,[index_type]       = i.[type_desc]
    ,[partition_count]  = p.partition_count
    ,[row_count]        = p.[rows]
    ,[data_compression] = CASE WHEN p.data_compression_cnt > 1 THEN 'Mixed'
                               ELSE (  SELECT DISTINCT p.data_compression_desc
                                       FROM sys.partitions p
                                       WHERE i.[object_id] = p.[object_id] AND i.index_id = p.index_id
                                    )
                          END
    ,[total_space_MB]   = cast(round(( au.total_pages                  * (8/1024.00)), 2) AS DECIMAL(36,2))
    ,[used_space_MB]    = cast(round(( au.used_pages                   * (8/1024.00)), 2) AS DECIMAL(36,2))
    ,[unused_space_MB]  = cast(round(((au.total_pages - au.used_pages) * (8/1024.00)), 2) AS DECIMAL(36,2))

Answer 3

对于 Azure，我使用了这个：

您应该拥有 SSMS v17.x+

我用过；

有了这个，作为用户Sparrow has mentioned：

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

SSMS 此处已连接到 Azure 数据库

Answer 4

如果您只关心数据库中浪费的空白空间而不关心单个表，则可以考虑以下事项：

如果数据库经历大量数据插入然后删除，可能就像在 ETL 情况下，这将导致数据库中过多的未使用空间，因为文件组 自动增长 但从不自动- 收缩。

您可以使用数据库的属性页面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，那么数据库将会重新增长（并且会花费额外的时间来尝试重新增长，并且事情会变慢，直到增长足够多 - 所以在这种情况下不要这样做）

Answer 5

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

Answer 6

以上查询对于查找表使用的空间量（包括索引）非常有用，但如果您想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

Answer 7

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

Answer 8

Mar_c's answer 的一个小改动，因为我经常回到这个页面，按大多数行的第一个排序：

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 

Answer 9

作为marc_s's answer（已被接受的那个）的一个简单扩展，它被调整为返回列数并允许过滤：

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

Answer 10

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

    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

@xav answer 的扩展，它处理表分区以获取以 MB 和 GB 为单位的大小。 在 SQL Server 2008/2012 上测试（注释了 is_memory_optimized = 1 的一行）

Answer 12

这是另一种方法：使用 SQL Server Management Studio，在 Object Explorer 中，转到您的数据库并选择 Tables

然后打开Object Explorer Details（按F7 或转到View->Object Explorer Details）。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 13

这是一种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中

   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Results to file (Ctrl + Shift kbd> + F)。

4. 现在终于点击了上面工具栏上标记为红色的执行按钮。

5. 数据库所有表的大小现在存储在您计算机上的一个文件中。

Answer 14

 exec  sp_spaceused N'dbo.MyTable'

对于所有表格，使用..（来自 Paul 的 cmets）

exec sp_MSForEachTable 'exec sp_spaceused [?]'

Answer 15

如果您使用的是 SQL Server Management Studio (SSMS)，您可以运行 而不是运行查询（在我的例子中返回重复的行）标准报告。

1. 右键单击数据库
2. 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。见http://msdn.microsoft.com/en-gb/library/bb510680.aspx

Answer 16

从命令提示符使用OSQL:

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

Answer 17

我们使用表分区，但由于重复记录，我们在上面提供的查询中遇到了一些问题。

对于需要此功能的用户，您可以在生成“按表的磁盘使用情况”报告时在 SQL Server 2014 运行的查询下方找到。我认为它也适用于以前版本的 SQL Server。

它就像一个魅力。

Answer 18

在上面的@Mark 答案上重复，添加了@updateusage='true' 以强制使用最新的尺寸统计信息（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

Answer 19

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临时表，然后从临时表中选择。

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

Answer 20

如果您需要在 SSMS 中的“表属性 - 存储”页面上计算完全相同的数字，则需要使用与 SSMS 中相同的方法来计算它们（适用于 sql server 2005 及更高版本.. . 并且也适用于具有 LOB 字段的表 - 因为仅计算“used_pa​​ges”不足以显示准确的索引大小）：

;with cte as (
SELECT

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

Answer 22

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

Answer 23

我的帖子只与 SQL Server 2000 相关，并且已经过测试可以在我的环境中工作。

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）、data（表的大小以 KB 为单位）、条目数据（我发现这有助于了解我上次运行脚本的时间）。

此代码的缺点是“数据”字段未存储为 int（字符“KB”保存在该字段中），这对于排序很有用（但并非完全必要）。

希望这段代码可以帮助那里的人并节省他们一些时间！

如果您需要了解，rsp_DatabaseTableSizes 表是通过以下方式创建的：

CREATE TABLE [dbo].[rsp_DatabaseSizes](
    [DatabaseName] [varchar](1000) NULL,
    [dbSize] [decimal](15, 2) NULL,
    [DateUpdated] [smalldatetime] NULL
) ON [PRIMARY]

GO

Answer 24

sp_spaceused 可以获得有关表、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

这会报告 ContactInfo 表的磁盘使用信息。

一次对所有表使用它：

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。要访问此报告，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 Reports，然后选择 Standard Reports，然后选择“Disk Usage by Partition: [DatabaseName]”。

Answer 25

这将为您提供每个表的大小和记录数。

Answer 26

经过一番搜索，我找不到获取所有表格信息的简单方法。有一个名为 sp_spaceused 的方便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
