how to get output

dbashyam has asked for the wisdom of the Perl Monks concerning the following question:

Hi Guys, I use the following code, I want to get the output as ORA-12505 in this scenario, but the number is dynamic, currently I am getting just numeric 1, how to get the output.

#!/usr/bin/perl
my $org = "";
$Ora_code = 'Failed tthe following error: ORA-12505, TNS:listener does
+ not currently know of SID given in connect descriptor';
print $Ora_code;
if ( my $out = $Ora_code =~ /ORA\-\d{5}/)
      {
        print "inside\n";
       print "$out\n";
     }
else {
print "(no match)\n";
}

Change: `my $out = $Ora_code =~ /ORA\-\d{5}/` to: `my ($out) = $Ora_code =~ /(ORA\-\d{5})/` . Adding the first set of parens causes `$out` to be treated as a one-element list. Without those parens, you have scalar context instead of list context; regex matches in scalar context return "truth" of the match instead of anything captured in the match. That Truth is represented as the "1" you are seeing. Adding the second set of parens declares what data should be captured when the regex is evaluated during the match.	[reply] [d/l] [select]

Hi, thanks for your reply. I did change now but still it prints output as '1', if you see my print statement I want to get the output as ORA-12505 in this scenario, but still not getting it right. `#!/usr/bin/perl my $org = ""; $Ora_code = 'Failed tthe following error: ORA-12505, TNS:listener does + not currently know of SID given in connect descriptor'; print $Ora_code; if ( my ($out) = $Ora_code =~ /ORA\-\d{5}/) { print "inside\n"; print $out; } else { print "(no match)\n"; }` [download]	[reply] [d/l]

As Util correctly mentioned, you need to enclose what you want captured within parentheses, so your regex should be: `/(ORA\-\d{5})/` [download]	[reply] [d/l]
