MONTHNAME
Description
The MONTHNAME function returns the English month name corresponding to a datetime value. This function supports processing DATE and DATETIME types, returning the full English month name (January to December).
You can set the language of the output result through the session variable lc_time_names, which is set to en_US
by default, meaning the output is in English.
This function behaves the same as MySQL's monthname function.
