Mastering MySQL Stored Procedures – Part 2: IN & OUT Parameters
In this video, we dive deeper into MySQL Stored Procedures, focusing on IN and OUT parameters. These parameters make stored procedures more dynamic and reusable by allowing data input and retrieval.
1️⃣ What Are IN & OUT Parameters in Stored Procedures?
✅ IN Parameter – Passes a value into the procedure, but cannot be modified inside it.
✅ OUT Parameter – Used to return a value from the procedure. The calling program receives the result.
✅ INOUT Parameter (Not covered in this part) – Acts as both input and output.
2️⃣ Why Use IN & OUT Parameters?
🚀 Make procedures reusable by allowing dynamic input.
🚀 Retrieve processed results directly from the procedure.
🚀 Reduce repetitive queries by centralizing logic in a stored procedure.
3️⃣ Use Case Examples:
🔹 IN Parameter:
Find the total sales for a given month.
Get student details by entering a student ID.
🔹 OUT Parameter:
Calculate discount percentage and return it.
Retrieve the maximum salary from an employee table.
📌 What You’ll Learn in This Video:
🔹 The difference between IN and OUT parameters in stored procedures.
🔹 How to pass input values and retrieve output values.
🔹 Best practices for creating and using parameterized stored procedures.
