PostgreSQL: advanced patterns with transactions and nested function calls
I'm building a feature where I'm prototyping a solution and Quick question that's been bugging me - I'm writing unit tests and I need help solving I'm working with an scenario with PostgreSQL when using nested functions inside a transaction... I have a situation where I want to insert records into two tables within a transaction, but when I call a function that performs the second insert, it seems to bypass the transaction scope. Here’s a simplified version of what I'm doing: ```sql CREATE OR REPLACE FUNCTION insert_into_table_a(data TEXT) RETURNS VOID AS $$ BEGIN INSERT INTO table_a (column_a) VALUES (data); END; $$ LANGUAGE plpgsql; CREATE OR REPLACE FUNCTION insert_into_table_b(data TEXT) RETURNS VOID AS $$ BEGIN INSERT INTO table_b (column_b) VALUES (data); END; $$ LANGUAGE plpgsql; BEGIN; PERFORM insert_into_table_a('Sample Data A'); PERFORM insert_into_table_b('Sample Data B'); COMMIT; ``` The question arises when I run this and I notice that the data from `table_b` is being inserted even if I later decide to roll back the transaction due to an behavior in another part of the process. I expected that if any part of the transaction fails, everything would roll back, but that's not happening. I tried using `SAVEPOINT` to handle this, but it's still not working as expected. I’m using PostgreSQL version 13 and I’ve checked that autocommit is set to off. I also tried explicitly using `BEGIN` and `COMMIT` within the functions, but it did not resolve the scenario. Is there something I'm missing, or is there a specific way I need to structure these function calls to ensure they respect the transaction scope? Any advice would be greatly appreciated! This is happening in both development and production on Debian. This is my first time working with Sql 3.10. Any help would be greatly appreciated! I'd be grateful for any help. I'm working on a service that needs to handle this. Any pointers in the right direction? What's the correct way to implement this?
