SQL GREATEST Function Explained

In SQL, the GREATEST function is used to return the maximum value from a list of parameters. It takes multiple parameters and returns the maximum value among them.

For example, the following SQL query utilizes the GREATEST function to return the maximum value in the given column:

SELECT GREATEST(column1, column2, column3) AS max_value
FROM your_table;

This will return the maximum value from column1, column2, and column3 and name the result as max_value.
