查询数据库大小

 总部要求每一个月，获取一次ERP数据库增长大小。我收到的样版是一张截图，是直接查看数据库文件大小。但Insus.NET想到的是，从下面的SQL语句，就可以查询到数据库大小。因此分享于此。 

SELECT DB_NAME(database_id) AS [Database Name],[Name] AS [Logical Name],[Physical_Name] AS [Physical Name],((size * 8) / 1024) AS [Size(MB)],[differential_base_time] AS [Differential Base Time]
FROM sys.master_files
WHERE DB_NAME(database_id) IN('XXX')
 
 GO
