If all you're looking for is to ensure both hashes are the same, then I'd highly recommend Data::Compare:
use strict;
use warnings;
use Data::Compare;
my %DS1=( PERL => [
{TABLES=>{ TABSCHEMA=>"VARCHAR(128)", TABNAME=>"VARCHAR(128)",
+ }}, # Tables and Columns are names of the tables.
{COLUMNS=>{ TABSCHEMA=>"VARCHAR(128)", TABNAME=>"VARCHAR(128)"
+, COLNAME=>"VARCHAR(128)", PARTKEYSEQ=>"SMALLINT", }}
]
);
my %DS2=( PERL => [
{TABLES=>{ TABSCHEMA=>"VARCHAR(256)", TABNAME=>"VARCHAR(128)",
+ }}, # Tables and Columns are names of the tables.
{COLUMNS=>{ TABSCHEMA=>"VARCHAR(256)", TABNAME=>"VARCHAR(128)"
+, COLNAME=>"VARCHAR(128)", PARTKEYSEQ=>"SMALLINT", }}
]
);
my $same = Compare(\%DS1, \%DS2);
print "$same\n"; # 0 (ie. false)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
