## Detailed Description

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.

mysqlpp::StoreQueryResult::operator private_bool_type | ( |  | ) | const`[inline]`

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.
