[MonetDB-users] Some questions

Hi everyone, I have a some questions about using monetDB. First thing I noticed when using extract on a timestamp field I can only cast the timestamp as year, month, day and so on. Is it somehow possible to extract the week of the year? Week starts with monday. Another thing is, can i use if statements in a query like i could in mysql? And the last one, i already searched in the archiv and found a post about win 32 odbc driver and column names which appear as questionmarks or other symbols like when using a wrong encoding, does anybody has the same problem or knows a solution? Regards Henning
