I am new to hibernate and i am using Hibernate Annotation. I have the following tables

LOOKUP_A
CDE_A

PARENT_CLASS
PARENT_ID

CHILD_CLASS
CHILD_ID
PARENT_NUM foreig key to PARENT_CLASS
CDE_A foreign key to -- LOOKUP-A

my problems is I am inserting a recond into PARENT_CLASS table and the same time it will insert child record based on parent id. It is inserting proper. But the problem is when child record is going to insert , it is calling select query on LOOKUP_A table and after that it is call INSERT statement on CHILD_CLASS. I don't want to SELECT statement before INSERTING a record into child table.
Please help me.
