virtual Status impala::ImpalaServer::QueryResultSet::AddOneRow	(	const std::vector< void * > &	row,
		const std::vector< int > &	scales
	)

pure virtualinherited

Add the row (list of expr value) from a select query to this result set. When a row comes from a select query, the row is in the form of expr values (void*). 'scales' contains the values' scales (# of digits after decimal), with -1 indicating no scale specified.

virtual int impala::ImpalaServer::AsciiQueryResultSet::AddRows	(	const QueryResultSet *	other,

	)

inlinevirtual

Copies rows in the range [start_idx, start_idx + num_rows) from the other result set into this result set. Returns the number of rows added to this result set. Returns 0 if the given range is out of bounds of the other result set.
