Hi there,
I am trying to add a foriegn key that references a primary key from another table.
To give a diagram view of it this is what I mean:

The tables are created as follows:
Subsequently the serialised-part table:
However when I add a contstraint as a foreign key I get the following error:
ORA-02298: cannot validate (GROUP7_1.SERIALISED-PART_CON) - parent keys not found
This is when I am adding Batch-no from serialised-part TABLE to the BATCH table
Thanks guys and I hope you go easy considering its my first post :D
