Output

The query returns only the rows needed for a reporting query.

Line-by-line explanation

  • Line 1 sets up the UPDATE example: UPDATE orders.

  • Line 3 adds the decision or filter that controls the result: WHERE id = 42 AND status = 'paid';.

Why this example is useful

This example is useful because it isolates update without surrounding noise, so you can see the idea clearly.
