In my application I'm using the long row type.

CREATE TABLE demo_long
(id_col NUMBER NOT NULL,
lonraw_col LONG RAW)
PCTFREE 10
PCTUSED 40
INITRANS 1
MAXTRANS 255
TABLESPACE tbs_data
STORAGE (
INITIAL 57344
NEXT 57344
PCTINCREASE 0
MINEXTENTS 1
MAXEXTENTS 2147483645
)

The problem is when I try to do an update hibernate uses this long type in the where clause...

Long types MUST NOT be in where, group by clauses.....somebody can help me to avoid this hibernate's behaviour??????
How can I deny hibernate to doing so??
