Which one of the following is a reason that an INSERT statement might cause an error instead of executing correctly? 1. The INSERT statement was attempting to insert a record into a view that was created from more than one table. 2. The INSERT statement was attempting to insert a record using a combination of constants and values from an existing table. 3. The INSERT statement was attempting to insert a record with a non-NULL value into a table that has that column defined as NULL. 4. The INSERT statement was attempting to insert a record into a table by selecting a record from that same table. 5. The INSERT statement was attempting to insert a record into a view rather than a table.
