[MonetDB-users] Problem with YEAR, MONTH, DAY functions

Hello, sorry to ask again but i have problem with YEAR, MONTH and DAY functions. According to the references YEAR for example can take as argument a date or a timestamp or a month_interval value. So if i run the query: sql> select year(current_timestamp); or sql> select year( '2002-03-21') it should return 2011 and 2002. Instead of this, i take: *syntax error,unexpected YEAR in: "select year". *What am i doing wrong? Thank you very much in advance
