DB2 Cursor explained with a real manufacturing example! Multiple Rows = Cursor.#shorts ##video#ibm

🚀 Why do we need a DB2 Cursor?

Let's understand it with a simple manufacturing example.

Imagine a quality inspector in a manufacturing plant inspecting 1,000 products. He cannot inspect all products at once. He checks one product, records the result, and then moves to the next.

A DB2 Cursor works exactly the same way.

When a query returns multiple rows, a Cursor processes them one row at a time, providing better control over data processing.

🎯 In this video you'll learn:
✅ Why we need a Cursor
✅ Real-life manufacturing example
✅ Cursor vs SELECT INTO
✅ When to use a Cursor in DB2

💡 Remember:
Single Row = SELECT INTO
Multiple Rows = CURSOR
