📄️ Common SQL Functions
SQL functions are built-in commands that are used to manipulate data in a relational database. They are a fundamental part of SQL (Structured Query Language) and are used to perform calculations, manipulate strings, dates, and perform other operations on data. SQL functions are a powerful tool that can make your SQL queries more dynamic and efficient.
📄️ Creating Your Own Functions
