SQL Server 2008: как запросить все размеры баз данных?

Имею MS SQL 2008 R2, 500 баз данных. Каков наиболее эффективный, простой и «современный» способ запроса баз данных любого размера.

На выходе должны быть столбцы:

• DatabaseName
• 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

Я не знаю точно, что вы подразумеваете под эффективностью, но это просто, и мне это подходит:

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

С такими результатами, как:

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

Примечание: был вдохновлен этой статьей

Вот простой, быстрый и надежный запрос, который предоставит все имена файлов базы данных и журналов, размеры, а также статусы базы данных (например, ONLINE) в красивом, легко читаемом выводе:

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

с заказанным общим размером базы данных Desc

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

Все кажется слишком сложным! Или я что-то упускаю?

Наверняка все, что вам нужно, это что-то вроде:

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

или если вам не нужен журнал:

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

Недавно я наткнулся на эту страницу в поисках чего-то вроде этого. На всякий случай, если кто-то столкнется с этим и заинтересован только в основных пользовательских базах данных, вы можете использовать что-то вроде этого, исключающее 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)

IF OBJECT_ID('tempdb.dbo.#space') IS NOT NULL
    DROP TABLE #space

CREATE TABLE #space (
      database_id INT PRIMARY KEY
    , data_used_size DECIMAL(18,2)
    , log_used_size DECIMAL(18,2)
)

DECLARE @SQL NVARCHAR(MAX)

SELECT @SQL = STUFF((
    SELECT '
    USE [' + d.name + ']
    INSERT INTO #space (database_id, data_used_size, log_used_size)
    SELECT
          DB_ID()
        , SUM(CASE WHEN [type] = 0 THEN space_used END)
        , SUM(CASE WHEN [type] = 1 THEN space_used END)
    FROM (
        SELECT s.[type], space_used = SUM(FILEPROPERTY(s.name, ''SpaceUsed'') * 8. / 1024)
        FROM sys.database_files s
        GROUP BY s.[type]
    ) t;'
    FROM sys.databases d
    WHERE d.[state] = 0
    FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 2, '')

EXEC sys.sp_executesql @SQL

SELECT
      d.database_id
    , d.name
    , d.state_desc
    , d.recovery_model_desc
    , t.total_size
    , t.data_size
    , s.data_used_size
    , t.log_size
    , s.log_used_size
FROM (
    SELECT
          database_id
        , log_size = CAST(SUM(CASE WHEN [type] = 1 THEN size END) * 8. / 1024 AS DECIMAL(18,2))
        , data_size = CAST(SUM(CASE WHEN [type] = 0 THEN size END) * 8. / 1024 AS DECIMAL(18,2))
        , total_size = CAST(SUM(size) * 8. / 1024 AS DECIMAL(18,2))
    FROM sys.master_files
    GROUP BY database_id
) t
JOIN sys.databases d ON d.database_id = t.database_id
LEFT JOIN #space s ON d.database_id = s.database_id
ORDER BY t.total_size DESC

Не для того, чтобы украсть ваш ответ и приспособить его для очков или чего-то еще, но вот еще одна факторизация:

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

Лучше и проще

SELECT [Database Name] = DB_NAME(database_id),
     [Type] = CASE WHEN Type_Desc = 'ROWS' THEN 'Data File(s)'
               WHEN Type_Desc = 'LOG'  THEN 'Log File(s)'
               ELSE Type_Desc END,
     [Size in MB] = CAST( ((SUM(Size)* 8) / 1024.0) AS DECIMAL(18,2) )
FROM   sys.master_files
--Uncomment if you need to query for a particular database
--WHERE      database_id = DB_ID(‘Database Name’) 
GROUP BY  GROUPING SETS
        (
               (DB_NAME(database_id), Type_Desc),
               (DB_NAME(database_id))
        ) ORDER BY      DB_NAME(database_id), Type_Desc DESC

Он предоставит вам размер файла (ов) данных и файла (ов) журнала отдельно, как показано ниже.

DatabaseName    Type            Size in MB
-------------------------------------------
FMS             Data File(s)    23.00
FMS             Log File(s)     1.50
PointOfSale     Data File(s)    4.00
PointOfSale     Log File(s)     1.25
Union2          Data File(s)    336.00

SurveyProject   Data File(s)    4.00
SurveyProject   Log File(s)     1.00

Следующий код сработал для меня очень хорошо.

    SELECT
        D.name As DbName,
        F.Name AS FullDbName,
        CASE WHEN F.type_desc='ROWS' THEN 'mdf' ELSE 'ldf' END AS FileType,
        F.physical_name AS PhysicalFile,
        CONVERT(DATE,D.create_date) AS CreationDate,
        F.state_desc AS OnlineStatus,
        CAST((F.size*8)/1024 AS VARCHAR(26)) + ' MB' AS FileSize_MB,
        CAST(F.size*8 AS VARCHAR(32)) + ' Bytes' AS FileSize_Bytes,
        CAST(CAST(ROUND((F.size*8)/(1024.0*1024.0),0) AS INT) AS VARCHAR(32)) + ' GB' AS FileSize_GB

    FROM 
        sys.master_files F
        INNER JOIN sys.databases D ON D.database_id = F.database_id

    ORDER BY
         D.name 

Упрощенная и улучшенная версия:

SELECT
    D.name,
    CAST(SUM(F.size) AS bigint) * 8*1024 AS SizeInBytes,
    CAST(SUM(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
GROUP BY D.name
ORDER BY SizeInBytes desc

иногда проблемы с БЕЗОПАСНОСТЬЮ не позволяют запрашивать все базы данных, и вам нужно запрашивать один за другим с префиксом db, для этих случаев я создал этот динамический запрос

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
