MDEV-23500: Assertion `!is_set() || (m_status == DA_OK_BULK && is_bulk_op())' failed in Diagnostics_area::set_ok_status upon multi-table update

Analysis: When NULL field is copied to NOT-NULL so there is error but this error is not reported so we get the failure. Fix: Return the error state.

with a single-table update I get MariaDB [test]> update t set f=NULL; ERROR 1048 (23000): Column 'f' cannot be null should multi-table update produce the same error?

+DROP TABLE t;
