Cursor.next()

NES2+Syntax

							cursor.next()

Description

The next() method of the Cursor object moves the point in the current row to the next row in the cursor. This method is used to iterate through each of the rows returned by the cursor. This method returns true, unless it is the last row of the cursor, at which time it returns false.

Example

Listing 8.34 creates an instance of the Cursor object and iterates through its results, deleting each row. This is performed by using the next() method.
