Why is it important to ensure the loop variable changes inside a WHILE loop in SQL procedures?

ATo automatically reset the variable after loop

BTo make the loop run faster

CTo prevent infinite loops and allow loop termination

DTo avoid syntax errors

Step-by-Step Solution

Solution:

Step 1: Understand loop termination condition
The loop runs while condition is true; variable must change to eventually become false.
Step 2: Consequence of no change
If variable never changes, condition stays true, causing infinite loop.
Final Answer:
To prevent infinite loops and allow loop termination -> Option C
