SQL Server 2008: come eseguire query su tutte le dimensioni di database?

124

Ho MS SQL 2008 R2, 500 database. Qual è il modo più efficiente, più semplice e 'moderno' per eseguire query su tutte le dimensioni di database.

L'output dovrebbe avere colonne:

  • Nome del database
  • 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

@Derek Smith - la colonna delle dimensioni è in pagine. La dimensione di una pagina è di 8 KB, quindi la formula SizeInMb = PagesCount * 8 / 1024. Ho sempre creduto che 1 MB = 1024 KB. Non penso che anche Microsoft abbia abbastanza potere per cambiare questo :).

Non so esattamente cosa intendi per efficienza, ma questo è semplice e funziona per me:

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

Con risultati come:

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

Ottengo valori NULL su ogni colonna usando questo? qualche idea sul perché?

se sys.master_files è vuoto, potrebbero essere permessi. Le autorizzazioni minime sono CREATE DATABASE, ALTER ANY DATABASE o VIEW ANY DEFINITION (ref: BOL sys.master_files)

Ecco una query semplice, rapida e affidabile che fornirà tutti i nomi, dimensioni e anche gli stati del database e dei file di registro (ad es. ONLINE) in un output piacevole e di facile lettura:

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

Tutto sembra troppo complicato! Oppure mi sfugge qualcosa?

Sicuramente tutto ciò che serve è qualcosa di simile:

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

o se non si desidera il registro:

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

Di recente mi sono imbattuto in questa pagina alla ricerca di qualcosa del genere. Nel caso in cui qualcuno si imbatta in questo e sia interessato solo ai database degli utenti principali, puoi usare qualcosa del genere che esclude Master, msdb ...

(CAST(mflog.LogSize AS FLOAT)*8)/1024 LogSizeMB

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'

Non rubare la tua risposta e adattarla per punti o altro, ma ecco un'altra fattorizzazione:

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

Uno migliore e abbastanza semplice 

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

Ti darà dimensioni di file di dati e file di registro separatamente come di seguito

        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

a volte i problemi di SICUREZZA impediscono di richiedere tutti i db ed è necessario interrogare uno per uno con il prefisso db, per quei casi ho creato questa query dinamica

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
