我在這個插入語句中遺漏了什麼？

Question

INSERT INTO GIADM.GI_TRANSFER_EMP(TRANSFER_EMP_ID,USER_ID,EMP_LAST_NAME, 
            EMP_FIRST_NAME,EMP_ACTIVE_FLAG) 
VALUES (select a.USER_ID as transfer_emp_id, 
      u.user_id as user_id, 
      u.user_last_name as emp_last_name, 
      u.USER_FIRST_NAME as emp_first_name, 
      u.USER_ACTIVE_FLAG as emp_active_flag 
    from db_user u, application_group_user a 
    where u.user_id in 
      (select a.user_id 
      from application_group_user a 
      WHERE a.APP_ID = 46 
       and a.SEC_GROUP_ID = 17) 
     and a.user_id = u.user_id); 

Answer 1

當你使用SELECT來填充INSERT語句不需要VALUES關鍵字：

INSERT INTO GIADM.GI_TRANSFER_EMP 
    (TRANSFER_EMP_ID,USER_ID,EMP_LAST_NAME,EMP_FIRST_NAME,EMP_ACTIVE_FLAG) 
SELECT a.USER_ID as transfer_emp_id, 
     u.user_id as user_id, 
     u.user_last_name as emp_last_name, 
     u.USER_FIRST_NAME as emp_first_name, 
     u.USER_ACTIVE_FLAG as emp_active_flag 
    FROM DB_USER u 
    JOIN APPLICATION_GROUP_USER a ON a.user_id = u.user_id 
           AND a.APP_ID = 46 
           AND a.SEC_GROUP_ID = 17 

Answer 2

的語法或者是

INSERT INTO tablename (columnnames...) VALUES (values...) 

或

INSERT INTO tablename (columnnames...) 
SELECT values 
FROM ...
