Syntax of creating partitions by binary column

[Andrey Kondakov]

Hi,

I created simple table under InnoDB engine:

a1 | CREATE TABLE `a1` (
`a` varbinary(16) NOT NULL DEFAULT '',
`b` varchar(20) DEFAULT NULL,
PRIMARY KEY (`a`)
ENGINE=InnoDB DEFAULT CHARSET=latin1

Now I am going to add partitions to my table using alter table statement:
mysql> alter table a1 partition by range(a) (
-> partition p0 values less than (0xba),
-> partition p1 values less than (0xcd)
-> )
-> ;
I get error
ERROR 1064 (42000): VALUES value must be of same type as partition function near '),
partition p1 values less than (0xba)
)' at line 2

Ok, I'm trying to create partitions using hash:
mysql> alter table a1 partition by hash(a)
-> partitions 16
-> ;
I get error
ERROR 1478 (HY000): The PARTITION function returns the wrong type

Where is the problem? Wrong syntax?

Thanks,

Andrey
