Enforce inserting only on the right datatype.

More correctly, you should be enforcing that the columns don't allow insertion of bad data at the database level, so your listed columns should be of integer type since they're ids, not of whatever type they are currently (varchar, perhaps). And you could then handle errors appropriately, e.g. by ignoring and discarding inappropriate data.
