getResultSet() cursor is initially positioned
before the first row; the first call to the method
next makes the first row the current row; the
second call makes the second row the current row, and so on.
If an input stream is open for the current row, a call
to the method next will
implicitly close it. A getResultSet() object's
warning chain is cleared when a new row is read.
