 先執行下面語法, 允許寫入 自動識別欄位, SET IDENTITY_INSERT [ TABLE_NAME] ON ; 再執行要異動的SQL, 最後再執行下面語法, 變更欄位為 不允許寫入   ( 因為自動識別欄位名稱要存在SQL內, 所以不能使用 select * from tableA的語法, 欄位要逐一列出, 並且包含自動識別欄位 ) ※ 只有在自動識別欄位出現在 INSERT INTO 陳述式的資料行清單中時，SET IDENTITY_INSERT 才能設置為 ON。 SET IDENTITY_ INSERT [ TABLE_NAME] OFF ; ref web: https://exfast.me/2016/09/mssql-automatic-identification-field-when-required-insert-when-information-should-be-how-do/
