You need to be able to generate primary key values on your own. 您需要能够自行生成主键值。 With IBM DB2, I am using sequences to get those values. 在IBM DB2中，我正在使用序列来获取这些值。 It would be good to know which RDBMS you are using. 最好知道您使用的是哪个RDBMS。
A statement matching your needs could look like that: 符合您需求的语句如下所示：
INSERT INTO MYSCHEMA.MYTABLE
select (NEXTVAL FOR MYSCHEMA.ID_SEQUENCE) as ID, T.*
from MYSCHEMA.MYTEMPTABLE T
