[TYPO3-mvc] [Extbase] Repository & SQL Functions

[Claus Fassing]

Hello,

is it possible to use SQL Functions from repositorys ?
e.g.
SELECT DATE_FORMAT( FROM_UNIXTIME(  `crdate` ) ,  '%Y' ) AS Datum
FROM tt_content group by Datum

Or do I have only the statement method for this on hand ?

Regards,

Claus
