In PostgreSQL, a variable is a meaningful name for a memory location. In Oracle a lot of people use the dbms_output package to return simple messages to the user’s screen. Unfortunately, there’s not a log written about how to use the OUT mode parameter in functions. Dynamic SQL is used to reduce repetitive tasks when it comes to querying. OS: Mac Postgres: 9 Dbeaver: Version 7.2.2.202010041557 (community edition) I typically execute a lot of stored procs in postgresql.
