sql server 复制表中的数据到另一张表

insert into userstate(NUSERID,USERCODE,CREATETIME,USERSTATE,ACCOUNTSTATE,UPDATETIME,UPDATEPASSWORD)  select NUSERID,USERCODE,'2018/12/13',1,0,'2018/12/13','2018/12/13' from user where USERCODE in (select USERCODE from fsys_USER EXCEPT select USERCODE from fsys_userstate);

'2018/12/13',1,0,'2018/12/13','2018/12/13',字段值可以不来自user表；
 NUSERID,USERCODE,来自user表；
