Hi, In a plpgsl function, consider the following excerpt:
DECLARE provider_id INTEGER; BEGIN provider_id := (SELECT provider_id FROM investment_products WHERE id = my_new.investment_product_id); END; After a lot of trouble, I found out this line doesn't work correctly with the variable name as it is. It doesn't give an error or anything, it just retrieves some wrong value (probably NULL). When I change the variable name to anything other than "provider_id", it works OK. I was somewhat surprised to discover this. Can't Postgres determine that the provider_id in the SELECT statement is not the same one as the variable?
