There are a number of ways to manage referential integrity.

You could disable the contraint:[^]

But you wouldn't be able to re-enable it until the data was fixed.

You can configure cascading deletes. This means any record linked through a foreign key would also be deleted.[^]

But this will change database behaviour and allow parent records to be deleted where you may want the presence of a child to create a blocking action.

So in short, no you can't truncate a table without dropping the constraint, but SQL does have mechanisms for helping with referential integrity.

Best way to Truncate Table

And you will still get the error that the OP got. You have resurrected a 4 year old question, that already has 3 accepted solutions, to post an incorrect answer. Stick to answering new questions where the OP still needs help and make sure you read the question and any responses carefully first.
