I don't know which columns are dates (so, I'll assume those prefixed with dt are). For your test script, you would have to change from

my $sth = $dbh->prepare_cached(
  "SELECT * FROM ReleaseDates"
);

my $sth = $dbh->prepare_cached(
  "SELECT convert( char(8), dtXXX, 101 ) FROM ReleaseDates" );
[download]

  my $sth =$connection->prepare(
    "SELECT Release, dtTargetFeatureFreeze, 
     dtTargetCCRB, dtTargetReleaseFromDev, 
     dtTargetRTM, TwikiURL, ReleaseNum, Display
     FROM ReleaseDates WHERE (Display = 1)"
  );
[download]

 my $sth =$connection->prepare(
    "SELECT Release, 
     convert( char(8), dtTargetFeatureFreeze, 1), 
     convert( char(8), dtTargetCCRB, 1),
     convert( char(8), dtTargetReleaseFromDev, 1), 
     convert( char(8), dtTargetRTM, 1),
     TwikiURL, ReleaseNum, Display
     FROM ReleaseDates WHERE (Display = 1)"
  );

update: BTW, setting dateformat only affects inputting dates.

Derby thank you so much !!! I have used your method on quite a few of my scripts now. Your an absolute legend. Thanks again for all your help. Michael I did try the whole

$dbh->syb_date_fmt('MDY1_YYYY');

but it just wouldn't workmaybe it was the way i was trying to include it into my script I will probably try and get it to work if i can. Thank you both for all your help
