MDY()
The MDY() operator
creates a date from month, day and year units.
Syntax
MDY ( expr1, expr2, expr3 ) - expr1 is an integer representing the month (from 1 to 12).
 - expr2 is an integer representing the day (from 1 to 28, 29, 30 or 31 depending on the month).
 - expr3 is an integer representing the year (four digits).
