const [pure virtual]

Return number of rows in results.

Implemented in rdbModel::MysqlResults.

virtual bool rdbModel::ResultHandle::getRow	(	std::vector< std::string > &	fields,
		unsigned int	i = 0,
		bool	clear = true
	)			[pure virtual]

Get array of field values for ith row of result set

Implemented in rdbModel::MysqlResults.

		unsigned long *	treesize,
		unsigned int *	runFrm,
		unsigned int *	runTo,
		unsigned int	i = 0,
		bool	clear = true
	)			[pure virtual]

virtual bool rdbModel::ResultHandle::getRowPtrs	(	std::vector< std::string * > &	fields,
		unsigned int	i = 0,
		bool	clear = true
	)			[pure virtual]

Get array of field values for ith row of result set. If a field value is NULL, return a zero ptr for that element of the array

--> It is the responsibility of the caller to delete the strings containing the field values. See service cleanFieldPtrs.

Implemented in rdbModel::MysqlResults.
