SQL Server 2008：如何查询所有数据库大小？

SQL Server 2008: How to query all databases sizes?

提问by Alex Aza

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“现代”的方法是什么？

The output should have columns:

输出应该有列：

• DatabaseName
• DataFilesSize
• LogFilesSize

• 数据库名称
• 数据文件大小
• 日志文件大小

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:

我不知道你所说的效率到底是什么意思，但这很简单，对我有用：

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

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:

这是一个简单、快速和可靠的查询，它将在一个漂亮的、易于阅读的输出中给出所有数据库和日志文件的名称、大小以及数据库状态（例如 ONLINE）：

SELECT
    D.name,
    F.Name AS FileType,
    F.physical_name AS PhysicalFile,
    F.state_desc AS OnlineStatus,
    CAST(F.size AS bigint) * 8*1024 AS SizeInBytes,
    CAST((F.size*8.0)/1024/1024 AS decimal(18,3)) AS SizeInGB
FROM 
    sys.master_files F
    INNER JOIN sys.databases D ON D.database_id = F.database_id
ORDER BY SizeInBytes desc

All seem overly complicated! Or am I missing something?

一切都显得过于复杂！或者我错过了什么？

Surely all you need is something like:

当然，您所需要的只是：

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:

或者如果您不想要日志：

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...

我最近遇到了这个页面，正在寻找这样的东西。以防万一有人遇到这个并且只对核心用户数据库感兴趣，你可以使用这样的东西，它不包括 Master、msdb ...

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

不要窃取您的答案并将其调整为分数或任何内容，但这是另一种分解：

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
