SQL Server 2008：如何查询所有数据库大小？
我有MS SQL 2008 R2，500个数据库。 什么是查询所有数据库大小的最有效，最简单和“现代”的方式。
输出应该有列：
- 数据库名称
- DataFilesSize
- LogFilesSize
with fs as ( select database_id, type, size * 8.0 / 1024 size from sys.master_files ) select name, (select sum(size) from fs where type = 0 and fs.database_id = db.database_id) DataFileSizeMB, (select sum(size) from fs where type = 1 and fs.database_id = db.database_id) LogFileSizeMB from sys.databases db 我不确切地知道你的意思是什么，但这是直接的，它适用于我：
SELECT DB_NAME(db.database_id) DatabaseName, (CAST(mfrows.RowSize AS FLOAT)*8)/1024 RowSizeMB, (CAST(mflog.LogSize AS FLOAT)*8)/1024 LogSizeMB, (CAST(mfstream.StreamSize AS FLOAT)*8)/1024 StreamSizeMB, (CAST(mftext.TextIndexSize AS FLOAT)*8)/1024 TextIndexSizeMB FROM sys.databases db LEFT JOIN (SELECT database_id, SUM(size) RowSize FROM sys.master_files WHERE type = 0 GROUP BY database_id, type) mfrows ON mfrows.database_id = db.database_id LEFT JOIN (SELECT database_id, SUM(size) LogSize FROM sys.master_files WHERE type = 1 GROUP BY database_id, type) mflog ON mflog.database_id = db.database_id LEFT JOIN (SELECT database_id, SUM(size) StreamSize FROM sys.master_files WHERE type = 2 GROUP BY database_id, type) mfstream ON mfstream.database_id = db.database_id LEFT JOIN (SELECT database_id, SUM(size) TextIndexSize FROM sys.master_files WHERE type = 4 GROUP BY database_id, type) mftext ON mftext.database_id = db.database_id
结果如下：
DatabaseName RowSizeMB LogSizeMB StreamSizeMB TextIndexSizeMB ------------- --------- --------- ------------ --------------- master 4 1.25 NULL NULL model 2.25 0.75 NULL NULL msdb 14.75 8.1875 NULL NULL tempdb 8 0.5 NULL NULL
注：受此文启发
这是一个简单，快速和可靠的查询，它将为所有数据库和日志文件名称，大小以及数据库状态（例如ONLINE）提供一个很好的，易读的输出：
SELECT D.name, F.Name AS FileType, F.physical_name AS PhysicalFile, F.state_desc AS OnlineStatus, CAST((F.size*8)/1024 AS VARCHAR(26)) + ' MB' AS FileSize, CAST(F.size*8 AS VARCHAR(32)) + ' Bytes' as SizeInBytes FROM sys.master_files F INNER JOIN sys.databases D ON D.database_id = F.database_id ORDER BY D.name
总数据库大小按顺序排列
SELECT DB_NAME(db.database_id) DatabaseName, (CAST(mfrows.RowSize AS FLOAT)*8)/1024 RowSizeMB, (CAST(mflog.LogSize AS FLOAT)*8)/1024 LogSizeMB, (CAST(mfrows.RowSize AS FLOAT)*8)/1024/1024+(CAST(mflog.LogSize AS FLOAT)*8)/1024/1024 DBSizeG, (CAST(mfstream.StreamSize AS FLOAT)*8)/1024 StreamSizeMB, (CAST(mftext.TextIndexSize AS FLOAT)*8)/1024 TextIndexSizeMB FROM sys.databases db LEFT JOIN (SELECT database_id, SUM(size) RowSize FROM sys.master_files WHERE type = 0 GROUP BY database_id, type) mfrows ON mfrows.database_id = db.database_id LEFT JOIN (SELECT database_id, SUM(size) LogSize FROM sys.master_files WHERE type = 1 GROUP BY database_id, type) mflog ON mflog.database_id = db.database_id LEFT JOIN (SELECT database_id, SUM(size) StreamSize FROM sys.master_files WHERE type = 2 GROUP BY database_id, type) mfstream ON mfstream.database_id = db.database_id LEFT JOIN (SELECT database_id, SUM(size) TextIndexSize FROM sys.master_files WHERE type = 4 GROUP BY database_id, type) mftext ON mftext.database_id = db.database_id ORDER BY 4 DESC
我最近遇到这个页面寻找这样的事情。 以防万一有人遇到这种情况，只对核心用户数据库感兴趣，你可以使用这样的东西排除Master，msdb …
SELECT DB_NAME(db.database_id) DatabaseName, (CAST(mfrows.RowSize AS FLOAT)*8)/1024 RowSizeMB, (CAST(mflog.LogSize AS FLOAT)*8)/1024 LogSizeMB FROM sys.databases db LEFT JOIN (SELECT database_id, SUM(size) RowSize FROM sys.master_files WHERE type = 0 GROUP BY database_id, type) mfrows ON mfrows.database_id = db.database_id LEFT JOIN (SELECT database_id, SUM(size) LogSize FROM sys.master_files WHERE type = 1 GROUP BY database_id, type) mflog ON mflog.database_id = db.database_id where DB_NAME(db.database_id) not like 'master' and DB_NAME(db.database_id) not like 'msdb' and DB_NAME(db.database_id) not like 'model' and DB_NAME(db.database_id) not like 'tempdb' and DB_NAME(db.database_id) not like 'Northwind' and DB_NAME(db.database_id) not like 'ReportServer' order by DB_NAME(db.database_id)
一切似乎过于复杂！ 还是我错过了什么？
当然，你需要的东西是这样的：
select d.name, case when m.type = 0 then 'Data' else 'Log' end, m.size * 8 / 1024 from sys.master_files m JOIN sys.databases d ON d.database_id = m.database_id
或者如果你不想要日志：
select d.name, m.size * 8 / 1024 from sys.master_files m JOIN sys.databases d ON d.database_id = m.database_id and m.type =0
SELECT DB.name, SUM(CASE WHEN type = 0 THEN MF.size * 8 / 1024 ELSE 0 END) AS DataFileSizeMB, SUM(CASE WHEN type = 1 THEN MF.size * 8 / 1024 ELSE 0 END) AS LogFileSizeMB FROM sys.master_files MF JOIN sys.databases DB ON DB.database_id = MF.database_id GROUP BY DB.name ORDER BY DataFileSizeMB DESC

有时SECURITY的问题阻止要求所有的数据库，你需要与数据库前缀一个接一个地查询，对于这些情况下，我创build了这个dynamic查询
