One-to-one:property-ref to a part of composite-key
Joined: Feb 27, 2006
I have 2 classes viz. Product and ProductBasic having one-to-one relationship
Product is mapped to a table PRODUCT which has PRODUCTID as PK.
ProductBasic is mapped to a table PRODUCTBASIC which has PRODUCTID,USECODE and STARTTTIME as composite key.
My database is legacy and i cannot change it.
I get the one-to-one relationship by applying the condition as:
PRODUCT.PRODUCTID=PRODUCTBASIC.PRODUCTID and USECODE='008' and STARTTIME < CURRENTIME < ENDTIME..
My database values are such that if i apply this condition i will only get once record..
