ilk SQL yazımda sizin için Bir sitede rastladığım 2 SP yi size göstermek istiyorum
ilk göstereceğim Script ile Netsis DB de bulunan table'lar için create scriptleri ve constraint create scriptleri generate edebiliyoruz
bu scriptleri drop ettikten sonra kullanarak tekrar create edebiliriz.
sonraki göstereceğim script ise yine table ve bu tableların constraintlerini drop etme scriptlerini generate edebiliyorsunuz.
