Description
Welcome to the PostgreSQL Full Playlist! ???? In this tutorial, we’re diving into String Concatenation Functions — concat() and concat_ws() — which make combining strings simple and flexible.

While the concatenation operator (||) works, PostgreSQL’s built-in functions provide more power, especially when dealing with NULL values and adding custom separators.

???? In this video, you’ll learn:

concat() → Join multiple values into a single string (ignores NULLs)

concat_ws() → Join strings with a custom separator (like commas or pipes)

Real-world use cases like building labels, formatting emails, and creating CSV-like output

Why these functions are often better than the || operator

By the end of this session, you’ll know how to combine strings smartly and safely in PostgreSQL, making your queries more readable and reliable.

✨ Great for SQL beginners, developers, and DBAs who want to improve text manipulation skills.
