When using Single Query Loading, mysqlType is interpreted as ENUM(247)

[sjh836]

The top screenshot doesn't use Single Query Loading, while the bottom does.

CREATE TABLE `car` (
  `car_no` BIGINT UNSIGNED NOT NULL AUTO_INCREMENT,
  `type` ENUM('SEDAN','SUV','VAN','TRUCK') NOT NULL,
  `created_at` DATETIME DEFAULT CURRENT_TIMESTAMP NOT NULL,
  PRIMARY KEY (`car_no`)
);

@Table("car")
@Getter
@ToString
public class CarEntity {
	@Id
	private int carNo;
	private CarType type;
	@CreatedDate
	private LocalDateTime createdAt;

	@PersistenceCreator
	public CarEntity(int carNo, CarType type, LocalDateTime createdAt) {
		this.carNo = carNo;
		this.type = type;
		this.createdAt = createdAt;
	}
}

public enum CarType {
	SEDAN,
	SUV,
	VAN,
	TRUCK,
}

Single Query Loading interprets the MySQL type enum directly, resulting in the following error.

As of the current date, I'm using the latest version: 3.5.4.
