Concept definition

template<typename QueryObject>
concept Lightweight::SqlNamedProjectionQueryObject =  SqlQueryObject<QueryObject> && requires(QueryObject const& queryObject) {
    { queryObject.ProjectedFieldNames() } -> std::convertible_to<std::span<std::string const>>;
    { queryObject.ProjectionHasWildcard() } -> std::convertible_to<bool>;
}

Detailed Description

Represents a query object that also knows the name of each column it projects.

Satisfied by the SELECT query builder's composed query, which records the caller-given name of every projected column as the projection is assembled. Statements executed from such a query object can resolve result columns by name — see the name-taking GetColumn overload of SqlResultCursor.
