SQL MIN and MAX with Alias. Alias in SQL is used to change the display name of a table or column. This feature is very helpful for increasing readability for the users. This is achieved using the AS keyword. Note: These Aliases are temporary names given for user’s convenience. Aug 22, 2017 2 min read. Lets try to build a RESTful API to do GET operation on a MySQL database. A lot of developers wants to map REST to CRUD directly, because REST over HTTP provides GET PUT. The MIN function returns the smallest value of the selected column. The MAX function returns the largest value of the selected column. For MIN, MySQL currently compares ENUM and SET columns by their string value rather than by the string's relative position in the set. This differs from how ORDER BY compares them.
