PL/pgSQL Course Syllabus

Duration : 1 Month

Category :PostgreSQL, pgSQL Database

Course Objective
Curriculum

The objective of the PostgreSQL PL/pgSQL course is to equip learners with strong procedural programming skills for building efficient, secure, and scalable database-driven applications using PostgreSQL’s native programming language, PL/pgSQL. This course focuses on developing the ability to write modular code, automate business logic, and enhance application performance through stored procedures, functions, triggers, and exception handling.

Learners will gain hands-on experience working with PL/pgSQL blocks, control structures, cursors, dynamic SQL, and advanced programming techniques. The course emphasizes writing optimized code, managing transactions effectively, and applying industry best practices for database programming within PostgreSQL environments.

By the end of the course, learners will be able to design and implement robust PL/pgSQL modules, streamline backend processes, and support enterprise applications—preparing them for roles such as PostgreSQL Developer, Database Programmer, Backend Engineer, and Application Developer.
