StoreQueryResult set type for "store" queries.
This is the obvious C++ implementation of a class to hold results from a SQL query that returns rows: a specialization of std::vector holding Row objects in memory so you get random-access semantics. MySQL++ also supports UseQueryResult which is less friendly, but has better memory performance. See the user manual for more details on the distinction and the usage patterns required.

Test whether the query that created this result succeeded.
If you test this object in bool context and it's false, it's a signal that the query this was created from failed in some way. Call Query::error() or Query::errnum() to find out what exactly happened.
