(MySQL查看数据库表容量大小)[https://www.cnblogs.com/vipsoft/p/12145059.html]
查询某数据库中的所有数据表
SELECT name as table_name
FROM sysobjects
WHERE xtype='u'
ORDER BY name
查询某数据库中的所有数据表及其数据总条数
SELECT a.name 数据表,
b.rows 数据总条数,
RTRIM(8 * b.dpages) + ' KB' 占用空间大小
FROM sysobjects AS a
INNER JOIN sysindexes AS b ON a.id = b.id
WHERE ( a.type = 'u' ) AND ( b.indid IN ( 0, 1 ) )
ORDER BY b.dpages DESC,b.rows DESC;
查询数据库文件路径信息
select * from sys.database_files
查询数据库文件大小
--当前数据库服务器所有数据库文件大小
SELECT DB_NAME(database_id) AS DatabaseName,
Name AS Logical_Name,
Physical_Name, (size*8.0)/1024 SizeMB
FROM sys.master_files
GO
--查看某一个数据库的文件大小
SELECT DB_NAME(database_id) AS DatabaseName,
Name AS Logical_Name,
Physical_Name, (size*8.0)/1024 SizeMB
FROM sys.master_files
WHERE DB_NAME(database_id) = 'database数据库名'
GO
SQL SERVER 统计每张表的大小
建存储过程
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
