Test plan (ktd):
1) reset_all
2) Run first part of the 241200017.pl atomicupdate manually
koha-mysql kohadev
ALTER TABLE illrequests DROP FOREIGN KEY illrequests_bnfk;
3) Create an ILL request linked to a borrower that doesn't exist (simulate old data):
INSERT INTO illrequests (`backend`, `borrowernumber`,`branchcode` ) VALUES ('Standard', '99999', 'CPL');
4) Run the 2nd part of the atomicupdate manually:
ALTER TABLE illrequests ADD CONSTRAINT illrequests_bnfk FOREIGN KEY(`borrowernumber`) REFERENCES `borrowers` (`borrowernumber`) ON DELETE SET NULL ON UPDATE CASCADE;
5) Notice you get the error:
ERROR 1452 (23000): Cannot add or update a child row: a foreign key constraint fails (., CONSTRAINT FOREIGN KEY () REFERENCES () ON DELETE SET NULL ON UPDATE CASCADE)
6) Run the added query in the patch:
UPDATE illrequests SET borrowernumber = NULL WHERE borrowernumber NOT IN (SELECT borrowernumber FROM borrowers);
7) Repeat step 4)
8) Notice there's no errors
