in thread Avoiding Strange Win32::ODBC Return Values for Integers (NUL)

That is right - I just wrote it to a file to be able to paste it, but pasting did not work from TextPad.
It tells me: can not copy... containing null (code=0) characters.
Notepad.exe does not show it nor complain, but also only shows a space when pasting it.

Update: It looks like 57.00[] while [] denotes the strange last character.

Thanks,
jonix

    I don't know why you're getting a NUL (ASCII character 0) in your output, but here's how we can get rid of it: 
    my $nul = chr(0);
$value =~ s/$nul//g;

    I would suggest that for all of the values coming out of the database; it's pretty likely that you don't want NULs in your output.

      Yes, thanks - this must be it!
      I will try it asap (after the weekend when I come back to my script) and also take the concise cleaning with regex approach :)

      Some questions still remain though:
      Is MSSQL, the ODBC Driver or Win32::ODBC introducing the NUL values?
      Is it a bug or a feature?

      Thanks again,

        I don't know, but MS-SQL you say? Is there any reason not to use DBI with DBD::ODBC? I don't know anything about Win32::ODBC, but I do know that I've used DBI with MS-SQL to great effect. If it's feasible, you might give this a shot. All things considered, having to clean the data is somewhat undesirable (though I'm sure someone will chime in with the fact that data from the database is marked as tainted, etc). Numbers should come back as numbers, not numbers with a NUL appended...
