SQL Server Stored Procedure Challenges

Create a Stored Procedure to Retrieve Orders

Write a stored procedure that accepts a customer ID and returns all orders placed by that customer.

Expected output: A stored procedure that returns filtered order records based on the customer ID.

Hint: Use input parameters and SELECT statements with WHERE clauses.

Implement Error Handling in a Stored Procedure

Modify an existing stored procedure to include TRY...CATCH blocks to handle potential errors during execution.

Expected output: A stored procedure that gracefully handles errors and returns informative messages.

Hint: Use BEGIN TRY and BEGIN CATCH blocks to capture errors.

Write a Procedure to Delete Inactive Users

Create a stored procedure that deletes users who have not logged in for over a year.

Expected output: A stored procedure that removes inactive user records safely.

Hint: Use date comparison in the WHERE clause to identify inactive users.

Stored procedures improve performance by reducing network traffic, promote code reuse, centralize business logic, and enhance security by controlling data access.

You can use TRY...CATCH blocks in T-SQL to catch and handle errors gracefully within stored procedures.

Stored procedures can perform actions like modifying data and do not have to return a value, while user-defined functions must return a value and cannot modify data outside their scope.
