What is the constructing question phrase in Turkish ?
Constructing question phrase in Turkish is very simple and straightforward. You just add "değil mi?" at the end regardless of the sentence. Examples; You are home, aren't you? --> Evdesin, değil mi? He did his homework, didn't he? --> Ödevini yaptın, değil mi? John will come today, won't he? --> John bugün gelecek, değil mi?

What are the advantages of using a stored procedure?
Stored Procedures are precompiled and stored in the database. This enables the database to execute the queries much faster. Since many SQL queries can be included in a stored procedure, round trip time to execute multiple queries from source code to database and back is avoided.
