How To Create And Call A Stored Procedure/Function With Refcursor As OUT...

In this video, we dive deep into the process of creating and calling stored procedures or functions with REFCURSOR as an OUT parameter in PostgreSQL. REFCURSOR is a powerful feature in PostgreSQL that allows you to return a cursor from a stored procedure, enabling you to handle result sets more flexibly.

First, we guide you through the process of defining a stored procedure or function with a REFCURSOR OUT parameter. You'll learn how to structure your SQL code to create a procedure that can return query results via a cursor.

Next, we demonstrate how to call this procedure or function from your PostgreSQL environment, retrieving the data returned by the REFCURSOR. We provide step-by-step examples to ensure you can follow along and implement these techniques in your own projects.

We also cover best practices for managing stored procedures with cursors, including tips on optimizing performance and avoiding common pitfalls. Whether you're a database administrator, developer, or just getting started with PostgreSQL, this video will help you unlock new capabilities in your database management.
