I have a table with only one Field ID type Serial Autonumeric and is a PK, i want insert a new record but it show me error Not null violation, but if i put a value the first INSERT work correctly but the next Insert it Show me error Unique violation,
So i try adding a new field in this table and put a value null to this field, and the ID Autonumeric work . Exist a way to do it only with a field, i'm working with PHP???
