Hello,

I have some code that I have run against MS SQL Server and Sybase ASE successfully. When I try to run it against a Sybase IQ server, there is a problem.

A temp table is created with a single varchar(25) field. Then a list of numbers are read from a file, leading zero's are pre-pended and I attempt to insert them one by one into the temp table.

The error returned is:

DBD::Sybase::st execute failed: Server message number=21 severity=14 state=0 line=0 text=SQL Anywhere Error -1000187: Unable to implicitly convert column 'PAT_MRN_ID' to datatype (varchar) from datatype (integer).

The code is:

my $crTmpMRN = qq{create table #mrns (PAT_MRN_ID varchar(25))};
$dbh->do($crTmpMRN);

my $mrn;
my $name;
my $fileRowCount=0;
my $dbRowCount=0;
my $distinctMRNCount = 0;
#for some reason SybaseIQ is trying to insert $mrn as an integer
my $insertMRNQuery = qq{insert #mrns (PAT_MRN_ID) values (?)};
my $sth=$dbh->prepare($insertMRNQuery);
open (MRNFILE,"$baseDir$mrn_file") or die "Can't read file $baseDir$mr
+n_file [$!]\n";
while (<MRNFILE>) {
    chomp ($_);
    ($mrn,$name)=split('\t',$_);
    #uses 10 character MRNs
    $mrn = substr '0000000000'.$mrn, -10;
    $sth->execute($mrn);
    $fileRowCount ++;
    print qq{'$mrn'\n};
}
close (MRNFILE);
print '$fileRowCount: '.$fileRowCount."\n";

I don't know much about the odbc drivers - I think it is odd that the error says "SQL Anywhere", but I am using the connection information that I was given. I have figured out a workaround - creating two columns in the temp table, inserting the numbers converted to varchar, then updating the values to the second column in the temp table. But really, I want to understand why it is attempting to insert $mrn as a numeric rather than a string.

Any help would be greatly appreciated!!
