Hi List, it was, as everytime when nobody answers, too easy ;) After searching again in the sqlstudio help I found what I need to solve it. I just didn't took the right keywords while searching last time.
The solution (if somebody else perhaps need this) is: update k_sonder_pos set liefertermin = Date( (SUBSTR(liefertermin,1,8)) & '0' & SUBSTR(chr(NUM(SUBSTR(liefertermin,9,2)) -1),1,1) ) where liefertermin <= '2007-01-31' and liefertermin >= '2007-01-01' Greetings, Frank -- MaxDB Discussion Mailing List For list archives: http://lists.mysql.com/maxdb To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
