Concept definition

template<typename T>
concept QxSql::sql_associative =  Qx::qassociative<T> &&
                           sql_convertible<typename T::mapped_type> &&
                           sql_keyable<typename T::key_type, typename T::mapped_type>

Detailed Description

Satisfied if T satisfies Qx::qassociative, T::mapped_type satisfies sql_convertible, and T::key_type + T::mapped_type satisfy sql_keyable.
