Body
You can use a simple type function based on partial specialization of a class template: <pre><code>#include <type_traits> #include <tuple> using namespace std; template<typename T> struct remove_first_type { }; template<typename T, typename... Ts> struct remove_first_type<tuple<T, Ts...>> { typedef tuple<Ts...> type; }; int main() { typedef tuple<int, bool, double> my_tuple; typedef remove_first_type<my_tuple>::type my_tuple_wo_first_type; static_assert( is_same<my_tuple_wo_first_type, tuple<bool, double>>::value, "Error!" ); } </code></pre> Also, this solution can be easily generalized to remove the i-th type of a tuple: <pre><code>#include <type_traits> #include <tuple> using namespace std; template<size_t I, typename T> struct remove_ith_type { }; template<typename T, typename... Ts> struct remove_ith_type<0, tuple<T, Ts...>> { typedef tuple<Ts...> type; }; template<size_t I, typename T, typename... Ts> struct remove_ith_type<I, tuple<T, Ts...>> { typedef decltype( tuple_cat( declval<tuple<T>>(), declval<typename remove_ith_type>::type>() ) ) type; }; int main() { typedef tuple<int, bool, double> my_tuple; typedef remove_ith_type<1, my_tuple>::type my_tuple_wo_2nd_type; static_assert( is_same<my_tuple_wo_2nd_type, tuple<int, double>>::value, "Error!" ); } </code></pre>

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.
