    <p>I have to match two hashtable, but its keys does not match. So i reach each hashtable and match by values. So following code does not works:</p> <pre><code>sub _findHashElt { my ($this, $hashTarget) = @_; my $isFound = 0; my $isItemFound = 1; my $isHashFound = 0; my $result = undef; my %hashTable=%{$this-&gt;{templates}}; my %hashTargetHash=%{$hashTarget}; my %hashSubTable = undef; while ( (my ($key, $value) = each(%hashTable)) and ($isFound == 0 )) { $isItemFound = 1; $isHashFound = 0; #################################### # DOES NOT WORK %hashSubTable = %{$hashTable{$key}}; #################################### while ( (my ($subKey, $subValue) = each(%hashTargetHash)) and ($isItemFound == 1 )) { $isItemFound = 0; while ( (my ($subTableKey, $subtableValue) = each(%hashSubTable)) and ($isItemFound == 0 )) { $isHashFound = 1; $isItemFound = ($subValue eq $subtableValue) ? 1 : 0; } } if ($isItemFound == 1 &amp;&amp; $isHashFound == 1) { $isFound = 1; $result = $key; } } return $result; } </code></pre> <p>And following code works:</p> <pre><code>sub _findHashElt { my ($this, $hashTarget) = @_; my $isFound = 0; my $isItemFound = 1; my $isHashFound = 0; my $result = undef; my %hashTable=%{$this-&gt;{templates}}; my %hashTargetHash=%{$hashTarget}; my %hashSubTable = undef; while ( (my ($key, $value) = each(%hashTable)) and ($isFound == 0 )) { $isItemFound = 1; $isHashFound = 0; while ( (my ($subKey, $subValue) = each(%hashTargetHash)) and ($isItemFound == 1 )) { #################################### # WORK %hashSubTable = %{$hashTable{$key}}; #################################### $isItemFound = 0; while ( (my ($subTableKey, $subtableValue) = each(%hashSubTable)) and ($isItemFound == 0 )) { $isHashFound = 1; $isItemFound = ($subValue eq $subtableValue) ? 1 : 0; } } if ($isItemFound == 1 &amp;&amp; $isHashFound == 1) { $isFound = 1; $result = $key; } } return $result; } </code></pre> <p>Please someone can tell me, what is the problem please ?</p> <p><strong>EDIT</strong></p> <pre><code>############################################# ################# TEST PART ################# ############################################# my $this = {"templates" =&gt; {}}; my $example = {'key0' =&gt; {'key00' =&gt; 'test00', 'key01' =&gt; 'test01', 'key02' =&gt; '0', 'key03' =&gt; 'test03'}, 'key1' =&gt; {'key00' =&gt; 'test10', 'key01' =&gt; 'test11', 'key02' =&gt; '1', 'key03' =&gt; 'test13'}, 'key2' =&gt; {'key00' =&gt; 'test20', 'key01' =&gt; 'test21', 'key02' =&gt; '1', 'key03' =&gt; 'test23'}, 'key3' =&gt; {'key00' =&gt; 'test30', 'key01' =&gt; 'test31', 'key02' =&gt; '0', 'key03' =&gt; 'test33'}}; my $expected = {'key00' =&gt; 'test00', 'key01' =&gt; 'test01', 'key02' =&gt; '0', 'key03' =&gt; 'test03'}; $this-&gt;{templates}=$example; _findHashElt($this, \%expected ); </code></pre> <p>In the first case, the key has not been found, and in the second the key has been found ...</p> <p><strong>EDIT</strong></p> <p>First case:</p> <pre><code>$ perl myTest.pl Key not found </code></pre> <p>Second case:</p> <pre><code>$ perl myTest.pl Key found { key01 : test01 key00 : test00 key03 : test03 key02 : 0 } </code></pre> <p><strong>EDIT</strong></p> <p>Another thing, i think it will be usefull</p> <pre><code>$ perl --version This is perl, v5.10.1 (*) built for i686-cygwin-thread-multi-64int (with 13 registered patches, see perl -V for more detail) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
