Dear Monks,
I have used a goto statement in the following bit of code. Is there a better way than this?
<background>
#! perl -w
use strict;
use warnings;
my @files;
my @List_of_commands;
my $line;
my $file;
while (<*.sql>) {
next if $_ eq 'Activate.sql';
push (@files, $_);
}
my $line_number;
foreach (@files) {
print $_;
$file = $_;
open (FILE, "<$file");
$line_number = 0;
while (<FILE>){
my $line = $_;
$line_number = $line_number +1;
if ($line_number == 1){
if ($line !~ m/ALTER\sPROCEDURE\s/){
#do nothing
}
else {
goto here;
}
}
$line = $_;
if ($line =~ m/INSERT INTO Message_pool/){
#Do nothing
}
elsif ($line =~ m/CREATE TABLE\s([A-Z|a-z|_]{1,200})\s.{0,100}/) {
my $table_name = $1;
my $Command = "if exists (select 1 from INFORMATION_SCHEMA.table
+s where table_name = '".$table_name."') DROP TABLE ".$table_name."";
push(@List_of_commands, $Command);
}
else {
#Do nothing
}
}
here:
}
my $outfile = "Outfile.txt";
foreach (@List_of_commands){
open (OUTFILE, "+>>$outfile");
print OUTFILE "$_\n"
}
