In MySQL there are three main data types: string, numeric, and date and time.

What is a numeric data type?

Numeric data types are numbers stored in database columns. These data types are typically grouped by: Exact numeric types, values where the precision and scale need to be preserved. The exact numeric types are INTEGER , BIGINT , DECIMAL , NUMERIC , NUMBER , and MONEY .
