Question

I have 2 tables:

PrimKey
001
002

And:

ID | ForeignKey
a  | 001
b  | 002
c  | 002

I want to delete, let’s say, row 002 and ‘bind’ all 002 foreign keys to 001, so it will look like:

PrimKey
001

And:

ID | ForeignKey
a  | 001
b  | 001
c  | 001

FK constraints do not allow me to do UPDATE + DELETE. Any tip where to dig?

Answer 1

You have to do it from the other direction. Change the rows in the second table to point to a different PK in the first table; then when there are no references to row002, you can delete it.
