sqlj.runtime.PositionedIterator 

sqlj.runtime.PositionedIterator extends ResultSetIterator

PositionedIterator is an interface implemented by all positional iterators declared by SQLJ. All such iterators depend on the position of the columns of the data to which they are bound, as opposed to the names of the columns to which they are bound.

In addition to implementing this interface, a class <class name> generated from a positional iterator declaration provides a positional accessor method for each column in the expected result set. The name of the positioned accessor method for the N-th column will be getColN(). The return type of the accessor method is the <java datatype> declared in the <java type list>.

Method

public abstract boolean endFetch () throws SQLException

This method returns true if the current row of the JDBC ResultSet underlying this iterator is not valid, false otherwise. This normally is the case if the current row is before the first or after the last row. Generally, the method is used to determine the success of a FETCH … INTO statement; it returns true if the last attempt to fetch a row failed, and returns false if the last attempt was successful. Rows are attempted to be fetched when the next() method is called (which is called implicitly during the execution of a FETCH … INTO statement).
