Java SQL database call into Multidimensional Array using Perl Script
Code:
#!/usr/local/bin/perl
use DBI;
use File::Copy;
use Time::Local;
use Data::Dumper;

-Comments Describing what I'm doing--------------
-I'm pulling information from a database that has an ID and Name. They are separated by a space and I'm trying to load them into a multidimensional array so as to manipulate Name of each element while keeping it's relationship to the ID constant.--------------------------

When I print #1, the information displays exactly how it should, but somewhere between the push and split function it goes wrong.

Code:
 $stm3 = $dbh->prepare($profile);
        $stm3->execute();
#       while (@row = $stm3->fetchrow_array)
        while (@row = $stm3->fetchrow()) {
#1               print "This is the Array: $row[0] $row[1]\n";
                @tmp = ([split / /, @row]);
                print "tmp is 0: $tmp[0] \n ";
#               push (@final, @tmp);
        #       print "E1: $final[0] E2: $final[1]\n";
        }

-I'm using the following statement to print out the results of the multi-dimensional array--------------------

Code:
for($i=0; $i<=$#final; $i++)
{
  print "i=$i\n";
  for($j=0; $j<2; $j++)
  {
    print " j = $j, Array: $final[$i][$j]";
  }
  print "\n";
}

Any thing will help.

jifty::dbi::handle::pg

Jifty::DBI::Handle::Pg(3pm)				User Contributed Perl Documentation			       Jifty::DBI::Handle::Pg(3pm)

NAME

	 Jifty::DBI::Handle::Pg - A Postgres specific Handle object

SYNOPSIS

DESCRIPTION

       This module provides a subclass of Jifty::DBI::Handle that compensates for some of the idiosyncrasies of Postgres.

METHODS

   connect
       connect takes a hashref and passes it off to SUPER::connect; Forces the timezone to GMT, returns a database handle.

   insert
       Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.

       In case of insert failure, returns a Class::ReturnValue object preloaded with error info

   id_sequence_name TABLE
       Takes a TABLE name and returns the name of the  sequence of the primary key for that table.

   blob_params column_NAME column_type
       Returns a hash ref for the bind_param call to identify BLOB types used by the current database for a particular column type.  The current
       Postgres implementation only supports BYTEA types.

   apply_limits STATEMENTREF ROWS_PER_PAGE FIRST_ROW
       takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW;

   _make_clause_case_insensitive column operator VALUE
       Takes a column, operator and value. performs the magic necessary to make your database treat this clause as case insensitive.

       Returns a column operator value triple.

   distinct_query STATEMENTREF
       takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.

   canonical_true
       The canonical true value in Postgres is 't'.

   canonical_false
       The canonical false value in Postgres is 'f'.
