How To Call A Stored Procedure From A Schedule Job Using pgAgent Jobs In...

In this tutorial, we dive into the world of automating PostgreSQL tasks by calling a stored procedure from a scheduled job using pgAgent in PostgreSQL. PgAgent is a powerful job scheduling tool that integrates seamlessly with PostgreSQL, allowing you to automate repetitive tasks such as running stored procedures, backups, and more.

We begin by guiding you through the setup of pgAgent in pgAdmin, ensuring that you have the necessary environment to start automating your database operations. Then, we move on to creating a stored procedure that performs a specific task within your database. This stored procedure will later be triggered automatically by a scheduled job.

The tutorial provides a step-by-step demonstration of how to create and configure pgAgent Jobs. You’ll learn how to set up schedules, define the tasks that need to be performed, and link these tasks to your stored procedures. We also discuss the various options available within pgAgent, such as setting execution frequency, handling job success or failure, and logging the job outcomes.

Additionally, we explore practical use cases where automating stored procedure execution can significantly enhance your database management strategy. Whether it’s for regular maintenance tasks, complex data manipulations, or timed reports, pgAgent Jobs provide a reliable and efficient solution.

By the end of this video, you'll have a solid understanding of how to use pgAgent to automate stored procedure calls in PostgreSQL, helping you streamline your database operations and save time.

In this video, we will see how to schedule a stored procedure

to call in pgAgent Jobs

In the last video, we have seen how to schedule a job.

In this video, we will call a stored procedure.

So, let's start.

How To Call A Stored Procedure From A Schedule Job Using pgAgent Jobs In PostgreSQL Database pgAdmin || PostgreSQL pgAgent 

-- Creating a table

CREATE TABLE public.emp

(

    id numeric,

    name character(30),

    salary numeric,

insert_date timestamp without time zone DEFAULT CURRENT_TIMESTAMP

);

-- Now we will create a stored procedure

CREATE OR REPLACE PROCEDURE public.testing_procedure()

LANGUAGE 'plpgsql'

AS $BODY$

DECLARE

BEGIN

Insert into emp(id,name,salary) values(1,'Akram Sohail',100);

Insert into emp(id,name,salary) values(2,'Knowledge 360',200);

END;

$BODY$;

CALL public.testing_procedure();

-- When this procedure will be called, two entries will be there in the Emp table.

-- Let's do it through a scheduled job using pgAgent Jobs

-- We have scheduled the procedure to be called every minute, every hour, every day, and all.

-- the First scheduler will be executed at 11:30 PM IST.

-- So, let's forward the video and wait.

Select * from emp;

-- There is no record as of now because the scheduler is not executed by now.

-- waiting...

-- We get two records at 11:30 PM as we can see from a timestamp.

-- Now, again new entries will come at 11:31 PM

-- So, our schedule job is working.

-- All the source codes and notes are in the description.

-- Please subscribe to my channel...Thank you :)
