I'm doing a check between a database and a csv-file. I got a list of values from database and I need to check if there are is a matching line in my csv file, i have to delete this line. At the end I got a csv-file with lines not stored in db now. Long story short, I got an if clause: 
my $dbval1 = "";
my $dbval2 = "";
my $val1 = "";
my $val2 = "";

if ($dbval1 eq $val1 && $dbval2 eq $val2)
{
  print "$dbval1 = $val1 && $dbval2 = $val2\n";
}

which is printing values which doesn't match. The values can be alphanumeric and the database is using varchar2.

Update: including some values: 
35000970 = 35000913 && AB00035515 = 11506
35000970 = 35000914 && AB00035515 = 121475
35000970 = 35000921 && AB00035515 = 58065

Update 2: I have no idea what was wrong, I stopped working on this and fixed another bug, now this works. Sry for no solution.
