One to many insert with iBatis

[Hussein Baghdadi]

Hi.
Consider these two tables: Order and OrderItem.
The relationship is one to many.
To save an order, two SQL command should be executed:
Insert a row in Order table (ORDER_ID is auto generated).
Insert a row in OrderItem table (OI_ID is auto generated and the primary key of the previous insert is needed in this command).
I'm trying to adopt iBatis and MySQL as the database.
The problem is I don't know how to get the PK of the first row in order to be passed to the second row?
Any ideas?
