Kullanıcı Tablolarında Bulunan İndexlerin Filegrouplarını Bulma

Primary filegroup üzerinde bulunan indexleri aşağıdaki kod ile bulabiliriz:

SELECT o.[name], o.[type], i.[name], i.[index_id], f.[name]
FROM sys.indexes i (nolock) INNER JOIN sys.filegroups f (nolock) ON i.data_space_id = f.data_space_id
INNER JOIN sys.all_objects o (nolock) ON i.[object_id] = o.[object_id]
WHEREo.type<>'s' and o.type='U' and f.name='PRIMARY'
ORDER BY o.name, i.name


Bu kod özellikle nesnelerinizi filegroup'lar arasında taşırken; özellikle "Hangi indexleri taşımadım?" sorusuna cevap niteliğinde.

Bir Veritabanının Büyümesini İzleme

Bir veritabanının büyümesini hızlı olarak aşağıdaki kod ile alabilirsiniz:

select
backup_start_date BackupDate
, floor(backup_size/1024000000) SizeGB
from msdb..backupset
where database_name = db_name()
and type = 'd'
order by backup_start_date desc

Askerlikten Damlalar

Siyaha boyanmış bir pencereden
Seyretmek zor dünyayı...
Hayatın henüz baharında
Solmaya başlamış gülü yeşertmek zor.

Ekip ruhundan yoksun insanlardan uzak dur!
Vakit doldu, yeni bir gün bitti; son budur...

Extended Property Nasıl Eklenir?

Bir tablo yada tablonun bir field'ına extended property nasıl eklenir? sorusuyla sık sık karşılaştığım için ekleme ihtiyacı hissettim.

--Tablonun extended property'sini ekleme
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'Tablo Aciklamasi’, @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'TabloAdi'
GO

--Field extended property'i ekleme
EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'İlgili fieldin Aciklamasi’, @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'TabloAdi', @level2type=N'COLUMN',@level2name=N'FieldAdi'
GO
