+ * This UpdateQuery is more for the cases where we want to build the where expression of the update using the

+ * <h4>Example: Simple update</h4>
+ *
+ * <pre>{@code

- * Both of the approaches defined in the JPA have significant problems!!!

- * </p>
- * <p>
- * Using the String values of enums is fairly restrictive because in a Database
- * these values are usually truncated into short codes (e.g. "A" short for
