I got error “The DELETE statement conflicted with the REFERENCE constraint”

Question

I tried to truncate a table with foreign keys and got the message:

\"Cannot truncate table because it is being referenced by a FOREIGN KEY co

Answer 1

You are trying to delete a row that is referenced by another row (possibly in another table).

You need to delete that row first (or at least re-set its foreign key to something else), otherwise you’d end up with a row that references a non-existing row. The database forbids that.
