    <p>I believe the following will do what you want. First you need a utility:</p> <pre><code>// make_tuple_indices template &lt;size_t...&gt; struct tuple_indices {}; template &lt;size_t _Sp, class _IntTuple, size_t _Ep&gt; struct make_indices_imp; template &lt;size_t _Sp, size_t ..._Indices, size_t _Ep&gt; struct make_indices_imp&lt;_Sp, tuple_indices&lt;_Indices...&gt;, _Ep&gt; { typedef typename make_indices_imp&lt;_Sp+1, tuple_indices&lt;_Indices..., _Sp&gt;, _Ep&gt;::type type; }; template &lt;size_t _Ep, size_t ..._Indices&gt; struct make_indices_imp&lt;_Ep, tuple_indices&lt;_Indices...&gt;, _Ep&gt; { typedef tuple_indices&lt;_Indices...&gt; type; }; template &lt;size_t _Ep, size_t _Sp = 0&gt; struct make_tuple_indices { static_assert(_Sp &lt;= _Ep, "make_tuple_indices input error"); typedef typename make_indices_imp&lt;_Sp, tuple_indices&lt;&gt;, _Ep&gt;::type type; }; </code></pre> <p>Then you can use this to help you expand a tuple holding your arguments:</p> <pre><code>template&lt;typename _Classname, typename... Args&gt; class CFunctorStartExT { friend class CXXFactory; protected: template&lt;typename U&gt; CFunctorStartExT(U&amp; _functor, Args&amp;... args) : m_Functor(_functor), m_args(args...) { } virtual bool ProcessLoop(CSomeClass* pThread) { return ProcessLoop(pThread, typename make_tuple_indices&lt;sizeof...(Args)&gt;::type()); } protected: _Classname&amp; m_Functor; std::tuple&lt;Args...&gt; m_args; private: template &lt;std::size_t ...Indx&gt; bool ProcessLoop(CSomeClass* pThread, tuple_indices&lt;Indx...&gt;) { return m_Functor(pThread, std::get&lt;Indx&gt;(m_args)...); } }; </code></pre> <p>As far as VS2010 variadic template support: I have no idea.</p>

    3. COThanks this solved a quite similar scenario I needed help with. Would it be okay to include your tuple_indices/make_tuple_indices code in an MIT-like licensed library? Licence can be viewed here: http://www.angelcode.com/angelscript/sdk/docs/manual/doc_license.html

Querying!

 
Guidance
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.

SQuiL has stopped working due to an internal error.

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