Mastering SQL - PostgreSQL: Pre-defined Functions - Case Conversion and Length

In this video, we dive deep into PostgreSQL's powerful case conversion and string length functions, helping you manipulate and validate string data effortlessly. Whether you're working with data transformations or string length validations, these functions will become essential tools in your SQL toolkit.

What this video covers:
✔️ Case conversion functions: lower, upper, initcap
✔️ Changing string case for business requirements
✔️ Using length to validate string length
✔️ Applying these functions to literals and table columns
✔️ Syntax and semantics of common string functions

💡 Learn how to convert strings to uppercase, lowercase, and title case, and how to validate string lengths in PostgreSQL.
