How can I handle errors in PostgreSQL?
In PostgreSQL, you can handle errors using the BEGIN, EXCEPTION, and END blocks in PL/pgSQL.
Can you give me an example of using EXCEPTION?
Sure! Here's a simple example:
BEGIN
-- Your SQL code here
EXCEPTION
WHEN unique_violation THEN
RAISE NOTICE 'A unique constraint violation occurred.';
END;
What types of exceptions can I catch?
You can catch various exceptions like division_by_zero, unique_violation, foreign_key_violation, and more.
Is there a way to log these errors?
Yes, you can log errors using the RAISE statement to output messages to the PostgreSQL log.
