Hi,

I am having problems with the output from a query. I am running perl on Win32, and I am connecting to an MS SQL database using the DBI ODBC driver.

I am doing a query by date. I use bind_columns to work with the results. I use a 'while (fetch())' to write out to a file.

My problem is the first row of my results isn't printed. Everything else prints out just fine. If I dump the array using "print OUTPUT "@rows";" the first row is there, so I know it is coming in my result set.

Is there a limitation on the number of columns I can return? Is there a better way to do this? I am programming and perl newbie.
This is essentially my script: 

#!perl

use strict;
use DBI;

my $g_date = '09/23/03';
open (OUTPUT, ">$somefile");
#create a header with column names
print OUTPUT "seq,prcdate,frb,account,amount,checknum,tc,disp,run,batc
+h,pkt,catcode,deviceid,volid,imagefile,status,typeid,bankId,itemNumbe
+r,editStatus,exceptionReasonCode,documentId,postAccount,appCode,bundl
+eImageOffset,bundleImageLength,archiveDeviceId,archiveVolId,archiveIm
+ageFile,archiveImageOffset,archiveImageLength,userIdAmountEntry,AUX,P
+C\n";
       

my $dbh = DBI ->connect ("DBI:ODBC:mydsn", "user", "password", { Raise
+Error => 1, AutoCommit => 0 });
my $sql = "Select *  from items where procdate = \'$g_date\' ";

my $sth = $dbh->prepare($sql);
$sth->execute()or die "\n\n  Unable to execute SQL query!\n\n";
my ($seq,$prcdate,$frb,$account,$amount,$check,$tc,$disp,$run,$batch,$
+pkt,$catcode,$deviceid,$volid,$imagefile,$status,$typeid,$bankId,$ite
+mNumber,$editStatus,$exceptionReasonCode,$documentId,$postAccount,$ap
+pCode,$bundleImageOffset,$bundleImageLength,$archiveDeviceId,$archive
+VolId,$archiveImageFile,$archiveImageOffset,$archiveImageLength,$user
+IdAmountEntry,$AUX,$PC);
my @rows = $sth->fetchrow_array;

my $rowcount = @rows;
if ($rowcount > 0) # don't do anything when no results
{
       $sth-> bind_columns( undef, \$seq, \$prcdate, \$frb, \$account,
+ \$amount, \$check, \$tc, \$disp, \$run, \$batch, \$pkt, \$catcode, \
+$deviceid, \$volid, \$imagefile, \$status, \$typeid, \$bankId, \$item
+Number, \$editStatus, \$exceptionReasonCode, \$documentId, \$postAcco
+unt, \$appCode, \$bundleImageOffset, \$bundleImageLength, \$archiveDe
+viceId, \$archiveVolId, \$archiveImageFile, \$archiveImageOffset, \$a
+rchiveImageLength, \$userIdAmountEntry, \$AUX, \$PC);             
       while( $sth->fetch() )
       {
             print OUTPUT "$seq,$prcdate,$frb,$account,$amount,$check,
+$tc,$disp,$run,$batch,$pkt,$catcode,$deviceid,$volid,$imagefile,$stat
+us,$typeid,$bankId,$itemNumber,$editStatus,$exceptionReasonCode,$docu

+rchiveDeviceId,$archiveVolId,$archiveImageFile,$archiveImageOffset,$a
+rchiveImageLength,$userIdAmountEntry,$AUX,$PC\n";    
       }
}
$dbh->disconnect();
close OUTPUT;
