    <p>You should try and follow <a href="https://stackoverflow.com/questions/10283610/how-to-change-a-template-method-based-on-whether-the-type-is-an-integral-or-floa/10284176#comment13229539_10283610">@DavidRodriguez's advice</a> and separate the common functionality of your class into a base class; then provide specializations of the whole derived class where functionality differs. That would be the better approach.</p> <p>If you do want to keep your current implementation, you can SFINAE the undesired version of the operator out of overload resolution as follows:</p> <pre><code>#include &lt;iostream&gt; #include &lt;type_traits&gt; template&lt;class T&gt; struct Matrix { // ... }; template&lt;class T&gt; typename std::enable_if&lt; std::is_integral&lt;T&gt;::value, bool &gt;::type operator==( const Matrix&lt;T&gt;&amp;, const Matrix&lt;T&gt;&amp; ) { std::cout &lt;&lt; "Integer version" &lt;&lt; std::endl; return true; } template&lt;class T&gt; typename std::enable_if&lt; !std::is_integral&lt;T&gt;::value, bool &gt;::type operator==( const Matrix&lt;T&gt;&amp;, const Matrix&lt;T&gt;&amp; ) { std::cout &lt;&lt; "Floating point version" &lt;&lt; std::endl; return true; } int main() { Matrix&lt;int&gt; m1, m2; Matrix&lt;double&gt; m3, m4; if( m1 == m2 ) {} if( m3 == m4 ) {} } </code></pre> <p>If you want the operators as member functions the only way I know of to make it work is to add a dummy template parameter to the operators and add <code>&amp;&amp; std::is_same&lt;T,U&gt;</code> to the <code>std::enable_if</code> test condition.</p>

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.
