Which is better SQL or procedure?

Conclusion. Overall, stored procedure outperforms dynamic SQL in almost all aspects. They are faster, secure, and easy to maintain, and require less network traffic. As a rule of thumb, stored procedures should be used in scenarios where you don’t have to modify your queries and your queries are not very complex.

Why stored procedure is faster than query?

“Stored procedures are precompiled and cached so the performance is much better.” This depends on the query, for simple queries it is best written and executed as a query itself.

What is the difference between a function and a stored procedure?

The main difference between stored procedure and function is that a stored procedure is a set of SQL statements that can be executed on the RDBMS again and again while a function is a set of instructions written using a programming language that can be executed again and again. A Relational…

What is the function of a stored procedure?

Unless function that returns only single value, stored procedures can return zero and many values at a time.

What are procedures and functions?

A procedure and function is a piece of code in a larger program. They perform a specific task. The advantages of using procedures and functions are: Reducing duplication of code. Decomposing complex problems into simpler pieces.

What is stored procedure return value?

A stored procedure can return an integer value called a return code to indicate the execution status of a procedure. So you should use this not to return data, but to return metadata about the execution of the procedure.
