HI y'all,
I'm facing an uncommon(I guess) situation. I've got to make a @OneToOne relationship between two tables and one of them has a composite-key('prefix' and 'number').
Let me explain it:
Code:
tableA
  +prefixNumber

tableB

  +prefix
  +number

the prefixNumber is exactly prefix + number concatenated; is there a way to make a relationship of these 2 tables using these attributes?
clear enough? :-)
