Iterator Methods

Both named and positional iterator objects have the following methods:

• rowCount()

  Returns the number of rows retrieved by the iterator object

• close()

  Closes the iterator; raises SQLException if the iterator is already closed

• isClosed()

  Returns TRUE after the iterator's close() method has been called; otherwise, it returns FALSE

Positional iterators also have the endFetch() method. The endFetch() method returns TRUE when no more rows are available.

Named iterators also have the next() method. The next() method advances processing to successive rows of the result set. It returns FALSE after it fails to find a row to retrieve. For an example of how to use the next() method, see Named Iterators.
