Than yu. ---------- Forwarded message --------- From: Igor Korot <ikorot01@xxxxxxxxx> Date: Tue, Jan 14, 2025 at 12:50 AM Subject: Lock in postgreSQL To: pgsql-generallists.postgresql.org <pgsql-general@xxxxxxxxxxxxxxxxxxxx>, PostgreSQL ODBC list <pgsql-odbc@xxxxxxxxxxxxxx> Hi, ALL, https://www.postgresql.org/docs/current/functions-admin.html#FUNCTIONS-ADVISORY-LOCKS There is an explanation about a promissory lock functions(). I have 2 questions about that: 1. Is calling one of them a way to get the lock()? 2. If I work on ODBC-based connection - I should call SQLExectDirect() with the function in question, correct? Thank you.
