Thanks @ll! It was in fact a char instead a varchar item. Von: firebird-support@yahoogroups.com [mailto:firebird-support@yahoogroups.com] Gesendet: Mittwoch, 25.

What tool/application are you using to evaluate the result? As Dmitry and Mark have already pointed out, the result should be a VarChar(10) (i.e. without any trailing spaces) It may be the tool/application handling the result which is adding the extra blanks.
