To change data (perform an INSERT
,
UPDATE
, or DELETE
) you use
the executeUpdate()
method. This method is
similar to the method executeQuery()
used to
issue a SELECT
statement, but it doesn't return
a ResultSet
; instead it returns the number
of rows affected by the INSERT
,
UPDATE
, or DELETE
statement.
Example 5.3, “Deleting Rows in JDBC” illustrates the usage.
