MySQL GREATEST Function Explained

The MySQL GREATEST function is used to return the maximum value in a given list of expressions.

It can take two or more arguments and return the maximum value among them. If the arguments contain a NULL value, the GREATEST function will return NULL.

For example, suppose there is a table called employees containing a column named salary. To find the highest salary in the salary column, you can use the following query:

Find the highest salary from the employees.

This query will return the maximum value in the salary column.
