Whether you are getting into PostgreSQL for the first time or an experienced developer wanting to explore function-writing more deeply, this course is for you. You will learn foundational knowledge of how to build your own functions in PostgreSQL.
At the core of a PostgresSQL database developer's toolkit is a thorough knowledge of how to build correct, efficient functions. In this course, Capturing Logic with Custom Functions in PostgreSQL, you will learn foundational knowledge of how to build your own functions in PostgreSQL. First, you will learn how to move from a basic query to a fully-parameterized function. Next, you will discover how to write your functions using PL/pgSQL, one of the many procedural languages available to the PostgreSQL developer. Finally, you will explore important matters relating to polymorphism, security, defensive programming and error handling. When you are finished, you will be able to solve real-world problems using PostgresSQL functions.
