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.
true
if the new current row is valid;
false

object.true
if the cursor is on a valid row;
false
if it is off the result setSQLException
- if a database access error
occurs or the result set type is TYPE_FORWARD_ONLY
