public abstract boolean next() throws SQLException
Returns
true if the new current row is valid; false if there
are no more rows
Description
A ResultSet is initially positioned before its first row; the
first call to next makes the first row the current row; the
second call makes the second row the current row, etc.
If an input stream from the previous row is open, it is
implicitly closed. The ResultSet's warning chain is cleared
when a new row is read.
Exceptions
SQLException
if a database-access error occurs.
