Re: Deleting Directories from a path by reading information from Database columns

[tokpela]

Are you looking for a way to delete the directories using the Id directory using the "number" column and base directory (c:\Documents and Settings\user\Files)?

If so, then check out remove_tree in the File::Path module.

remove_tree( $dir1, $dir2, ...., \%opts )

The remove_tree function deletes the given directories and any files and subdirectories they might contain, much like the Unix command rm -r or del /s on Windows.

use strict;
use warnings;

use DBI;
use File::Path;

my $base_directory   = 'c:/Documents and Settings/user/Files';

my $db               = DBI->connect( "dbi:Oracle:*****", "*****", "***
+***" )
                           || die( $DBI::errstr . "\n" );

$db->{AutoCommit}    = 0;
$db->{RaiseError}    = 1;
$db->{ora_check_sql} = 0;
$db->{RowCacheSize}  = 16;

my $SEL              = "SELECT  number,id,status FROM info where statu
+s in ('I,D')";
my $sth              = $db->prepare($SEL);
$sth->execute();

while ( my $row = $sth->fetchrow_hashref() ) {

   my $folder    = $row->{number};    # folder
   my $subfolder = $row->{Id};        # subfolder

   my $directory = "$base_directory/$folder/$subfolder";
   
   if (-d $directory) {
   
      if (remove_tree($directory)) {
      
         print "DIRECTORY HAS BEEN DELETED:: [$directory]\n";
      
      } else {
      
         print "[Error] UNABLE TO DELETE DIRECTORY: [$directory]\n";
      
      }
   
   }
   
}

Hi, I tried your code and it is showing the following errors:
Use of uninitialized value in concatenation (.) or string at ./db0.pl line 29.

Use of uninitialized value in concatenation (.) or string at ./db0.pl line 29.

Undefined subroutine &main::remove_tree called at ./db0.pl line 35.

line 29 is : my $directory = "$base_directory/$folder/$subfolder";

You need to import remove_tree, as I said in an earlier post.

And can you please do the most rudimentary of debugging to see what is undefined? Obviously your data doesn't look like you think it does.

Hi, Based on the script above all the values are initialized. So not sure why these errors are coming up and I changed remove_tree to rmtree.

so it is going to the $basedirectory location and deleting the whole thing
