How To Create Triggers In PostgreSQL || How To Create Trigger Function I...

In this comprehensive tutorial, we delve into the world of triggers in PostgreSQL, showing you how to create both triggers and trigger functions from scratch. Triggers are a powerful feature in PostgreSQL that allow you to automatically execute a function when certain events occur on a table, such as INSERT, UPDATE, or DELETE operations.

We start by explaining the concept of triggers and their importance in maintaining data integrity and automating routine tasks. You’ll learn how to define a trigger function, which contains the logic that will be executed when the trigger is fired. From there, we guide you through the process of creating a trigger that links this function to a specific table, ensuring that your database reacts automatically to changes.

The video includes detailed, step-by-step examples, making it easy for you to follow along and implement these techniques in your own PostgreSQL environment. We also cover best practices for managing and optimizing triggers, ensuring that they perform efficiently without negatively impacting your database.

Whether you're a database administrator, developer, or just starting with PostgreSQL, this tutorial will equip you with the knowledge needed to effectively use triggers to automate and secure your database operations.

select * from students_logs;

update students set name = 'Akram Sohail' where roll = 1;

update students set name = 'Akram Sohail (Modified)' where roll = 1;

delete from students where roll = 1;

----------------------------------------------------------------------------------------------

Triggers are special types of functions that are called/invoked/executed/performed automatically as per the trigger event declaration. A trigger is usually set before or after updating, deleting, insert DML statements on a table. That means, whenever a record is to be inserted, updated, or deleted, based on the time of execution which can be before or after, the trigger executes. Generally, the execution of the Trigger is called “Trigger Fired”.

In PostgreSQL, to create a trigger and make it usable, the sequence of object creation will be:

•   Create a Table on which a trigger to be implemented

•   Create another table to keep logs, so we can see the Trigger work

•   Create a Trigger Function that holds the trigger

•   Create the Trigger Function and Define the Trigger Logic

•   Perform Insert/Update/Delete Operations on the Table

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 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 :)
