Hello, I tried your samples, thank you. But my installation wouldn't work with place holders. $sql = "insert into $tableName (KUNDENNUMMER) values (?)"; $sth = $dbh->prepare($sql); # works $sth->execute(@field[0]) || die("Can't execute statement: $sth::errstr"); # does not work In the documentation on www.perldoc.com are the same samples like you gave me bevore. It seems that I have the wrong version or a wrong installation. I use the following environment: Windows 2000 (sorry :-( ), MS SQL over ODBC on a different server, the Active State version of perl and downloaded this file: DBI-1.20.tar.gz Can anybody tell me, that similar installations work correctly? Also, I don't see any message from the 'die(...: $sth::errstr' part. Please send a cc for this thread to [EMAIL PROTECTED] Then I am able to find solutions on weekend.
