getRowPtrs()

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.
