Good day bros. I am having an odd DBI problem. I have a subroutine that I am using to fetch a value from MySQL:
sub getsqlvalue {
my @results = ();
my ($dbh,$sqlstatement)= @_;
my $sth = $dbh->prepare($sqlstatement);
my @row;
$sth->execute || die "Could not execute MySQL statement: $sqlstate
+ment";
while (@row=$sth->fetchrow_array) { push(@results, [ @row ]); }
$sth->finish();
return $results[0][0];
}
I run this to get a value and it works fine. I then run it again to get another value (from the same field only with a different where condition) and it returns nothing.
So I set a breakpoiint in the debugger inside this sub and copied and pasted the contents of $sqlstatement into the MySQL command line client, and it gave the proper value. I then continued execution, and the value came back null. DBI returns no errors.
What could explain this?!? How can I debug?
