Why stored procedures are needed in SQL - Quick Recap

Recall & Review

beginner

What is a stored procedure in a database?

A stored procedure is a set of SQL statements saved in the database that can be executed repeatedly as a single unit.

beginner

How do stored procedures improve performance?

Stored procedures run on the database server, reducing data transfer and allowing the server to optimize execution, which makes queries faster.

beginner

Why do stored procedures help with security?

They allow controlling access to data by letting users run procedures without giving direct access to the underlying tables.

intermediate

How do stored procedures help maintain consistency?

They ensure that complex operations are done the same way every time, reducing errors and keeping data consistent.

beginner

What is one advantage of using stored procedures for code reuse?

Stored procedures let you write SQL code once and use it many times, saving effort and avoiding mistakes from rewriting code.

What is a main reason to use stored procedures?

A To improve query performance by running code on the server

B To store images in the database

C To replace database backups

D To create user interfaces

Stored procedures run on the database server, which helps improve performance.

How do stored procedures help with security?

A By blocking all user access

B By encrypting all data automatically

C By allowing users to run code without direct table access

D By storing passwords in plain text

Stored procedures let users execute code without giving them direct access to tables.

Which of these is NOT a benefit of stored procedures?

A Automatic database scaling

B Improved data consistency

C Code reuse

D Better performance

Stored procedures do not handle database scaling automatically.

Stored procedures help reduce errors by:

A Allowing users to edit SQL code freely

B Ensuring operations run the same way every time

C Deleting old data automatically

D Backing up the database

They keep operations consistent, reducing mistakes.

Where do stored procedures run?

A On a separate application server

B On the user's computer

C In the web browser

D On the database server

Stored procedures execute on the database server.

Explain why stored procedures are useful for improving database security.

Think about how stored procedures limit what users can do directly.

Describe how stored procedures help with performance and consistency in databases.

Consider both speed and reliability benefits.
