How To Call A Stored Procedure/Function From A Trigger Function In Postg...


In this tutorial, you will learn how to call a stored procedure or function from a trigger function in PostgreSQL. This video is designed for developers and database administrators who want to automate tasks or enforce business rules by leveraging the power of triggers in PostgreSQL. We'll begin by explaining what triggers are and how they work within a PostgreSQL database. Next, we'll walk you through the process of creating a trigger function that can invoke a stored procedure or function whenever a specific event occurs in your database, such as an insert, update, or delete operation. You'll see practical examples and gain insights into how this powerful feature can enhance your database applications. By the end of this tutorial, you'll be confident in your ability to implement triggers that call stored procedures or functions, adding a new level of automation and functionality to your PostgreSQL projects.

Working with triggers is fun and learning. There are endless possibilities that can be achieved through Triggers.

This time, I have explained the usage of Triggers to call other stored procedures or functions in PostgreSQL Trigger Functions.

CREATE TABLE students
(
    roll numeric(10,0),
    name character varying(30),
    course character varying(30)
);


CREATE OR REPLACE PROCEDURE 
trigger_proc(in_value1 IN numeric, in_value2 IN numeric, out_result OUT numeric)
LANGUAGE 'plpgsql'
AS $BODY$
Declare
lv_msg CHARACTER varying(100);
Begin
  out_result := in_value1 + in_value2;
exception
when others then
lv_msg := 'Error : '||sqlerrm;
raise notice '%',lv_msg;
end;
$BODY$;


CREATE OR REPLACE FUNCTION 
trigger_func(in_value1 IN numeric, in_value2 IN numeric) returns numeric
LANGUAGE 'plpgsql'
AS $BODY$
Declare
lv_msg CHARACTER varying(100);
out_result numeric (10);
Begin
  out_result := in_value1 + in_value2;
return out_result;
exception
when others then
lv_msg := 'Error :'||sqlerrm;
raise notice '%',lv_msg;
end;
$BODY$;


CREATE OR REPLACE FUNCTION student_logs_trg_func()
    RETURNS TRIGGER
    LANGUAGE 'plpgsql'
AS $BODY$
declare
lv_out_proc numeric(10);
lv_out_func numeric(10);
begin
call trigger_proc(50, 50, lv_out_proc);
lv_out_func := trigger_func(100, 100);
raise notice 'Proc Output: %',lv_out_proc;
raise notice 'Func Output: %',lv_out_func;
return new;
end;
$BODY$;


CREATE TRIGGER student_trg
    BEFORE INSERT OR DELETE OR UPDATE 
    ON students
    FOR EACH ROW
    EXECUTE FUNCTION student_logs_trg_func();

Insert into students values (1, 'Akram', 'MCA');
