What is the primary reason to include a termination condition in the recursive part of a CTE?

ATo prevent infinite recursion and ensure query completion

BTo improve query readability

CTo define the data type of the output column

DTo optimize the anchor member execution

Step-by-Step Solution

Solution:

Step 1: Understand recursion termination
Termination condition stops recursion when a certain condition is met.
Step 2: Consequence of missing termination
Without it, recursion runs indefinitely causing errors or resource exhaustion.
Step 3: Other options are unrelated
Termination condition is not primarily for readability, data type, or anchor optimization.
Final Answer:
To prevent infinite recursion and ensure query completion -> Option A
Quick Check:
Termination stops infinite loops [OK]
