Hash Index for Unique Varchar field in MyIsam

[veledrom]

Hi,

I have table (MyIsam) and want to set an index but fail to do so.

Field : Varchar(10) Not Null
Index Type : Unique
Index Method : Hash

Everytime I try, index method automatically assigned as BTree. Is this combination wrong for setting an index defined above?

Thanks
