sql-server - 有没有办法找出你的数据库表的大小？

Question

我的 sql 2008 服务器中有大约 10 个表。

目前，我的 mdf 大约是 3.5Gig。（我在一些表中也有一些二进制数据）。所以，我想知道是否有一种方法可以查看哪些表是最大的。

这可能吗？

也许它是一个索引或 FTS 目录？

运行这个：

/******************************************************************************

编辑要解析的代码，单引号中的几个字符使用特殊的单引号，以及 -- 符号。

此代码适用于 Microsoft SQL 2005+

Answer 2

exec sp_spaceused [tablename]

Answer 3

sys.allocations_units包含您需要的信息。您加入sys.partitions以将分区的所有分配单元组合在一起，并获得更有用的 object_id 而不是深奥的 allocation_unit_id。

select object_name(p.object_id),
    sum(au.total_pages)*8 as [space_in_kb]
    from sys.partitions p
    join sys.allocation_units au on p.hobt_id = au.container_id
    group by p.object_id
    order by [space_in_kb]  desc

是的，所有表（堆或集群）都是' partitions'，这些术语不指分区表。sys.partitions 也有您可能感兴趣的“行”列。

Answer 4

 exec sp_spaceused <tablename>

Answer 5

此查询显示当前数据库中每个表的大小。

SELECT sysobjects.[name] AS [TableName],
    SUM(sysindexes.reserved) * 8 AS [Size(KB)],
    SUM(sysindexes.dpages) * 8 AS [Data(KB)],
    (SUM(sysindexes.used) - SUM(sysindexes.dpages)) * 8 AS [Indexes(KB)],
    (SUM(sysindexes.reserved) - SUM(sysindexes.dpages)) * 8 AS [Unused(KB)]
FROM dbo.sysindexes AS sysindexes
    JOIN dbo.sysobjects AS sysobjects ON sysobjects.id = sysindexes.id
WHERE sysobjects.[type] = 'U'
GROUP BY sysobjects.[name]
ORDER BY [Size(KB)] DESC

Answer 6

在 SQL 2008+ 中：右键单击 SSMS 中的 DB 名称，选择Reports，然后Standard Reports，然后Disk Usage by Table。

Answer 7

有时我会运行它...它将所有表获取到临时表，将其循环并获取所有表的大小。结果数据在@tablesizes 中，因此您可以随意查询。

适用于 Sql Server >2005

declare @tables TABLE
(
    table_name nvarchar(200)
)

declare @tablesizes TABLE
(
    [name] nvarchar(200),
    [rows] int,
    reserved nvarchar(200),
    data nvarchar(200),
    index_size nvarchar(200),
    unused nvarchar(200),
    reserved_int int,
    data_int int,
    index_size_int int,
    unused_int int
)

declare @t nvarchar(200)

insert into @tables
select Table_Name from information_schema.tables

while exists(select * from @tables)
begin
    set @t=(select top 1 table_name from @tables)

    insert into @tablesizes([name],[rows],reserved,data,index_size,unused)
    exec sp_spaceused @t

    delete top (1) from @tables
end

update @tablesizes set 
reserved_int=convert(int, replace(reserved,' KB','')),
data_int=convert(int, replace(data,' KB','')),
index_size_int=convert(int, replace(index_size,' KB','')),
unused_int=convert(int, replace(unused,' KB',''))

select * from @tablesizes order by data_int desc

Answer 8

你可以使用：

SELECT @@servername;

IF EXISTS(SELECT name FROM tempdb.sys.tables WHERE name LIKE '#spaceUsed%')
    BEGIN
        DROP TABLE #spaceUsed;
    END;
CREATE TABLE #spaceUsed  (
name VARCHAR(255) ,
rows INT ,
reserved VARCHAR(50) ,
data VARCHAR(50) ,
index_size VARCHAR(50) ,
unused VARCHAR(50));

EXEC sp_msforeachtable
@command1 =' 
--
INSERT INTO #spaceUsed
exec sp_spaceused N''?'';
'
,@whereand = ' And Object_id In (Select Object_id From sys.objects
Where SCHEMA_NAME(Schema_ID) like ''%'')';

DECLARE
   @spaceUsedData TABLE  (
   name VARCHAR(255) ,
   rows INT ,
   reservedMB BIGINT NULL ,
   dataMB BIGINT NULL ,
   index_sizeMB BIGINT NULL ,
   unusedMB BIGINT NULL);

INSERT INTO INTO @spaceUsedData (name , rows , reservedMB , dataMB ,index_sizeMB ,unusedMB)
SELECT                  name , rows ,
Convert ( BIGINT ,Ltrim(Rtrim(Replace(reserved ,'KB' ,'')) ))/1024 ,
Convert ( BIGINT ,Ltrim(Rtrim(Replace(data ,'KB' ,'')) ))/1024 ,
Convert ( BIGINT ,Ltrim(Rtrim(Replace(index_size ,'KB' ,'')) ))/1024 ,
Convert ( BIGINT ,Ltrim(Rtrim(Replace(unused ,'KB' ,'')) ))/1024
FROM #spaceUsed;

SELECT * , reservedMB+  dataMB+index_sizeMB+unusedMB AS TotalMB FROM @spaceUsedData
ORDER BY rows DESC;
