[Solved] Given this block:DO $ BEGIN PERFORM 10 / 0; EXCEPTION WHEN division_by_zero THEN RAISE NOTICE 'Handled division by zero error';... END $;What will be the output? | PostgreSQL

PostgreSQL - Advanced PL/pgSQL

Given this block:

DO $$
BEGIN
  PERFORM 10 / 0;
EXCEPTION
  WHEN division_by_zero THEN
    RAISE NOTICE 'Handled division by zero error';
  WHEN OTHERS THEN
    RAISE NOTICE 'Other error caught';
END $$;

What will be the output?

ANOTICE: Handled division by zero error

BNOTICE: Other error caught

CERROR: division by zero

DNo output, block completes silently

Step-by-Step Solution

Solution:

Step 1: Identify the error
The expression 10 / 0 causes a division_by_zero error.
Step 2: Check exception handlers
There is a specific handler for division_by_zero and a generic WHEN OTHERS handler.
Step 3: Determine which handler executes
The division_by_zero handler matches and runs first.
Final Answer:
NOTICE: Handled division by zero error -> Option A
Quick Check:
Specific exception handlers take precedence over WHEN OTHERS [OK]

Quick Trick: Specific exceptions handled before WHEN OTHERS [OK]

Common Mistakes:

Expecting the generic WHEN OTHERS handler to run first
Assuming the error will propagate without notice
