A non-key field can be any field in the table that is not the primary key. During the process of normalisation identifying non-key fields is important, as they and other fields may be moved and new tables created. Foreign keys will be left in the table.

In Microsoft Access you can insert a record directly via the table object, execute an append query, enter a record into a data bound form or write a record programatically via the recordset object. In Access an identity column is referred to as a Primary Key. If the Primary Key column's data type is set to autonumber then the column is read only and will automatically be assigned the next unique number (datatype long) within that table. If the Primary Key column's data type is NOT set to autonumber then you must provide a unique, non-null value when adding the record. Append Query on a table with an autonumber Primary Key: Insert into tbl_Test (Test_FirstName, Test_LastName) Values ('George', 'Washington') Append Query on a table with an non-autonumber Primary Key: Insert into tbl_Test (Test_Id, Test_FirstName, Test_LastName) Values (1,"George","Washington")
