in thread Even though there are two separate database handles error shows need two separate database handles to compare

I like to look at database issues but I've never used this module. It looks pretty awesome. So as curious as I was I decided to try it. In order to replicate the issue I made a little sample script. When I tried to use:

$oDB_Comparison->deep_compare(@aTable_Names);

I get several errors that are very familiar to me from some work with DBIx::Class. You need to have tables defined a certain way in DBIx::Class for the deep->compare to work (or so it seems to me). But you can use the basic compare without seeing the errors:

$oDB_Comparison->compare(@tables);

Also, unless I have this line in my code:

$oDB_Comparison->verbose;

no results print, so you want to add that in I think. You need to check your definition of $dbh1 and $dbh2 like mje said.

my $dbh1 = DBI->connect('DBI:DATABASE_TYPE:DATABASE_NAME:DATABASE_SERV +ER','USERNAME','PASSWORD') || die "Error Connecting to \$dbh1: ".$DBI +::errstr."\n";

Also see DBIx::Class

#!/usr/bin/perl use strict; use warnings; use DBI; use DBIx::Compare; my $dbh1 = #SEE sample connect line above my $dbh2 = #SEE sample connect line above my $oDB_Comparison = db_comparison->new($dbh1, $dbh2); my @tables = ('Table1', 'Table2); $oDB_Comparison->verbose; $oDB_Comparison->compare(@tables);
