Use MySQL's built-in tools to calculate values, transform data, compare results, and build smarter queries.
MySQL provides a large collection of functions and operators that can be used directly inside SQL queries. You can perform calculations, manipulate strings, work with dates, handle NULL values, and calculate aggregates without moving the data into your application first.
Operators such as comparison, logical, arithmetic, and conditional operators let you build more expressive queries. Knowing which work should happen inside MySQL and which belongs in application code can also make your backend simpler and more efficient.
