I have enum: public enum MyEnum { ValueOne, ValueTwo }; I have entity with column: @Column(nullable = true, length=255) @Enumerated(EnumType.STRING) public MyEnum myEnum; Table in DB have colmun of size 1020 (varchar 1020), but I specified length = 255, if length = 80, then column varchar 320, if length 40 column 160. It seems than engine multiples length by 4. Why is so? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962214#...
