Hello,
I am trying to get data from a Sybase DB using DBI and DBD::ODBC.
I have tested the connection using fixed values in the code, but when I try to pass a variable or placeholder, as in the code below, I get the following error message:
DBD::ODBC::st execute failed: [MERANT][ODBC Sybase ASE driver][SQL Ser
+ver]Implicit conversion from datatype 'VARCHAR' to 'NUMERIC' is not a
+llowed.  Use the CONVERT function to run this query.

And I can't seem to locate anything on the CONVERT function in DBI.

Here's the query I am trying to run:
use DBI;

   my $dbh = DBI->connect('dbi:ODBC:Data Source', 'username', 'passwor
+d', {RaiseError => 1,});
        my $sth = $dbh->prepare('SELECT customercode FROM customerorde
+rs WHERE ordercode = ?')
                or die "Couldn't prepare statement: " . $dbh->errstr;

    print "Enter ordercode> ";
    while ($ordercode = <>) {               # Read input from the user
      my @data;
      chomp $ordercode;
          $sth->execute($ordercode)             # Execute the query
            or die "Couldn't execute statement: " . $sth->errstr;

          # Read the matching records and print them out          
          while (@data = $sth->fetchrow_array()) {
            my $customercode = $data[1];
            my $ordercode = $data[2];
            print "\t $customercode $ordercode\n";

Now I've searched through PerlMonks and on the Web and I can't find any solution to this problem, other than suggestions that I use a different DBD driver, such as DBD::Sybase. I have downloaded and installed that driver but I am having trouble getting it to work.
I also tried bind_param, as follows:
$sth->bind_param(1, $ordercode, SQL_INTEGER); with no success.
Has anyone come up with a way to pass variables in a query to a Sybase DB using DBD::ODBC on Win32?

Thank you,
