Detailed Description

A ResultSet object is not updatable and has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row.

The ResultSet interface provides getter methods for retrieving column values from the current row. Values can be retrieved using the index number of the column. Columns are numbered from zero (0).

For the getter methods, a given driver attempts to convert the underlying data to the C++ type specified in the getter method and returns a suitable value.

A ResultSet object MUST be closed when done, which will automatically handle freeing the memory associated with the object.

NOTE: Only getString will return NULL if the database had a NULL value stored, the rest will return ZERO!
