SQL - Triggers

Why can nested triggers cause performance problems and how can this be avoided?

ANested triggers do not affect performance at all

BNested triggers improve performance by parallel execution

CNested triggers cause cascading executions; avoid by disabling nested triggers or limiting logic

DNested triggers automatically optimize themselves

Step-by-Step Solution

Solution:

Step 1: Understand nested trigger behavior
Nested triggers cause one trigger to fire another, increasing execution time.
Step 2: Avoid cascading effects
Disabling nested triggers or simplifying logic prevents performance degradation.
Final Answer:
Nested triggers cause cascading executions; avoid by disabling nested triggers or limiting logic -> Option C
Quick Check:
Nested triggers = Cascading calls = Slower performance [OK]

Quick Trick: Avoid nested triggers to prevent cascading slowdowns [OK]
