if the result was never used, free the resources results used already (getresult called) are expected to be deleted

SetPreparedResult()

void SQLQueryHolderBase::SetPreparedResult	(	std::size_t	index,

store the result in the holder

}

SetSize()

void SQLQueryHolderBase::SetSize

(

std::size_t

size

)

to optimize push_back, reserve the number of queries about to be executed

{
    m_queries.resize(size);
}
