We will be discussing the MAX aggregate function in SQL, which retrieves the largest value in a column. It's the opposite of the MIN function, which retrieves the smallest value.
The syntax is similar to the MIN function, just replacing MIN with MAX. When using aggregate functions, always ensure the column's data type is numeric or integer to get accurate results. If the data type is VARCHAR, the function will treat it as a string.
