The following code works fine on my local machine, but it inserts duplicate records on my shared server. I am starting with a CSV file that contains 40,000 records, of which I only want to insert 7,000--my stored procedure decides if a record gets inserted or not. The server is usually inserting about 10,000 records, 3,000 of which are duplicates. I am calling the perl script as a cgi script. This is a mystery to me. (Local machine: Vista/MS SQL 2k5/ODBC DSN, Server: MS Server 2K3/MS SQL 2K5/ODBC DSN). Thanks for your help. 
use DBI;
my $dbh = DBI->connect( "$dbServer", "$dbUser", "$dbPass" ) or print "
+Could not make connection to database";

open(DAILY, "$updateDir/$fileName") || print "CAN'T OPEN DAILY";


while(<DAILY>){
    chomp;
    my ($field1,$field2,$field3,$field3,$field4,$field5,$field6,$field
+7,$field8) = split(/,/);
            
    if ($field1 == 33){
                
                my $spQuery = "exec my_sp ?,?,?,?,?,?,?";
                
                $insert33 = $dbh->prepare( $spQuery ) or die ( "Cannot
+ prepare statement: ", $dbh->errstr(), "\n" );
            
                $insert33->execute($field1,$field2,$field3,$field4,$fi

                or die( "Cannot execute statement: ", $insert33->errst
