how to select by month/day?

[Ted Vinke]

Hi!   I need to select a series of persons who have been born in this month and show them ordered by their birthday.   I've stored the birthday as a LONG in the person builder, but unfortunately the following constructions sorts the persons by the *entire* birthday.   <mm:list            path="person"            fields="person.firstname,person.lastname,person.birthday"            orderby="person.birthday"            >   Is there a way to sort by another date-component instead of year, such as the day of the month? Is there an easy MMBase wat of doing this, or would I have to use scriptlets to add all these persons to a Vector first and then somehow sort it by day?   Regards, Met vriendelijke groet, Ted Vinke   First8 BV Groenestraat 294 6531 JC Nijmegen [EMAIL PROTECTED]
