Hi all ,
I'm pretty new to hibernate and i'm working on a module which consists of 3 tables namely Doc_fees_master , Test_fees_master and there is an itemised_bill table , and the relation is as follows
itemised_bill - ID , Fees_id , fees_type
doc_fees_master - ID , fees , Doctorname , specialization
test_fees_master - ID , testname , fees
Now the fees_id field in itemised_bill is the ID field of doc_fees_master , so it could be like Fees_id=1 can exist in both doc_fees_master and test_fees_master , or in any one of them .
Ex : if fees_id=1 and fees_type=1 , then it means it's a foreign key to doc_fees table
if fees_id=1 and fees_type=2 , then it means it's a foreign key to test_fees table
i'm using hibernate and i tried to map many-to-one relation on fees_id(itemised_bill) to both
doc and
test tables , which doesn't work , because same column cannot be referenced to 2 different tables , please let me know the right mapping to be done in hibernate using XML file and not annotations.
my objective is that , i would like to join itemised_bill and doc_fees and test_fees in so that with one foreign key fees_id , so that ill get the bill itinerary or a particular person .
Thank you
