SQL Server veritabanımın boyutunu nasıl belirlerim?

Temel: MS SQL Server DB diskimin boyutu nedir?
Daha fazlası: Verilerin nerede olduğunu hızlıca görebilir miyim? hangi tablolar, günlükler, vb.

Muhtemelen sp_spaceused komutuyla başlamak isteyeceksiniz.

Örneğin:

sp_spaceused Veritabanının toplam boyutu hakkında bilgi verir

sp_spaceused 'MyTable' MyTable'ın boyutu hakkında bilgi döndürür

Bilgi alabileceğiniz her şeyin belgelerini okuyun. Ayrıca sp_msforeachtable komutunu kullanarak sp_spaceused komutunu aynı anda tüm tablolarda çalıştırabilirsiniz.

Düzenleme: Komutun bazen her biri farklı bir istatistik kümesi içeren birden çok veri kümesi döndürdüğünü unutmayın.

En kolay yol (yazma yok!): Management Studio'dan SQL 2005/8'de veritabanını sağ tıklatın, Raporlar, Standart Raporlar, Disk Kullanımı'nı (ayrıca Üst Tablolara, Tablo ve Bölüme Göre) seçin.

Bu komut dosyası, geçerli veritabanındaki tüm tablolarda dolaşır ve her birinin veri, dizinler ve kullanılmayan alan için ne kadar yer kapladığını gösterir:

Fiziksel dosyaları sys.database_files. Bu dosya ve boyut (IIRC bloklar halinde) yolu vardır.

sp_spaceused size tek bir nesnenin ne kadar yer kapladığını gösterecektir.

tablo başına boyutu almak için bunu çalıştırın:
