SQL Server 2008:如何查询所有数据库大小?

I have MS SQL 2008 R2, 500 databases. What is the most efficient, easiest and 'modern' way to query all databases sizes.

我有MS SQL 2008 R2, 500个数据库。查询所有数据库大小的最有效、最简单和最“现代”的方法是什么?

The output should have columns:

输出应该有列:

• DatabaseName
• 数据库名
• DataFilesSize
• DataFilesSize
• LogFilesSize
• 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

I don't know exactly what you mean by efficiency but this is straightforward and it works for me:

我不知道你说的效率是什么意思，但这很简单，对我来说很有用:

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

With results like:

结果:

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

Here's a simple, quick and reliable query that will give all database and log file names, sizes and also database statuses (e.g. ONLINE) in a nice, easy to read output:

这里有一个简单、快速、可靠的查询，它将提供所有的数据库和日志文件名称、大小以及数据库状态(例如在线)，并提供一个漂亮、容易阅读的输出:

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

有了数据库大小，命令Desc。

All seem overly complicated! Or am I missing something?

都显得过于复杂!还是我漏掉了什么?

Surely all you need is something like:

当然你所需要的是:

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

or if you don't want the log:

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

I recently came across this page looking for something like this. Just in case someone comes across this and is interested in only the core user databases, you can use something like this which excludes Master, msdb...

我最近在这个页面上看到了这样的东西。如果有人遇到这种情况，并且只对核心用户数据库感兴趣，您可以使用这样的方法来排除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)

Not to steal your answer and adapt it for points or anything, but here is another factorization:

不是为了窃取你的答案并将其应用于点或任何东西，但这里有另一个分解:

select d.name, 
    sum(m0.size*8.0/1024) data_file_size_mb, 
    sum(m1.size*8.0/1024) log_file_size_mb 
from sys.databases d
inner join sys.master_files m0 on m0.database_id = d.database_id
inner join sys.master_files m1 on m1.database_id = d.database_id
where m0.type = 0 and m1.type = 1
group by d.name, d.database_id
order by d.database_id

sometimes SECURITY issues prevent from asking for all the db's and you need to query one by one with the db prefix, for those cases i created this dynamic query

有时，安全问题会阻止请求所有数据库，您需要用db前缀逐个查询，对于这些情况，我创建了这个动态查询。

go
declare @Results table ([Name] nvarchar(max), [DataFileSizeMB] int, [LogFileSizeMB] int);

declare @QaQuery nvarchar(max)
declare @name nvarchar(max)

declare MY_CURSOR cursor 
  local static read_only forward_only
for 
select name from master.dbo.sysdatabases where name not in ('master', 'tempdb', 'model', 'msdb', 'rdsadmin');

open MY_CURSOR
fetch next from MY_CURSOR into @name
while @@FETCH_STATUS = 0
begin 
    if(len(@name)>0)
    begin
        print @name + ' Column Exist'
        set @QaQuery = N'select 
                            '''+@name+''' as Name
                            ,sum(case when type = 0 then size else 0 end) as DataFileSizeMB
                            ,sum(case when type = 1 then size else 0 end) as LogFileSizeMB
                        from ['+@name+'].sys.database_files
                        group by replace(name, ''_log'', '''')';

        insert @Results exec sp_executesql @QaQuery;
    end
  fetch next from MY_CURSOR into @name
end
close MY_CURSOR
deallocate MY_CURSOR

select * from @Results order by DataFileSizeMB desc
