Question

我遇到了许多类似于上述标题的查询。但我的情况完全不同。我正在尝试为具有INSERT查询的表运行SELECT命令以填充列值。下面是我正在尝试执行的查询。

INSERT INTO ELEC_ORDER_HT (OMS_SEQ.NEXTVAL, CUST_ID, ORDER_DATE, SHIP_METHOD,
  REC_CREN_TM, REC_HIST_CREN_TM AS '23-NOV-17 01.56.01.103000 AM', ORDER_ID) 
SELECT ELEC_ORDER.CUST_ID AS CUST_ID, ELEC_ORDER.ORDER_DATE AS ORDER_DATE,
  ELEC_ORDER.SHIP_METHOD AS SHIP_METHOD, ELEC_ORDER.REC_CREN_TM AS REC_CREN_TM,
  ELEC_ORDER.ORDER_ID AS ORDER_ID
FROM ELEC_ORDER
WHERE ELEC_ORDER.CUST_ID = 'CSTMR10001'
AND ELEC_ORDER.ORDER_ID = 'ELORD10001';

ELEC_ORDER_HT和ELEC_ORDER表中的列数不同。执行上述查询时出现以下错误。

  REC_CREN_TM, REC_HIST_CREN_TM AS '23-NOV-17 01.56.01.103000 AM', ORDER_ID)
                                *
ERROR at line 2:
ORA-00917: missing comma

如何解决此问题？

Answer 1

INSERT INTO ELEC_ORDER_HT (
  OMS_SEQ.NEXTVAL, -- This does not appear to be a column name
  CUST_ID,
  ORDER_DATE,
  SHIP_METHOD,
  REC_CREN_TM,
  REC_HIST_CREN_TM AS '23-NOV-17 01.56.01.103000 AM', -- you cannot use aliases here
  ORDER_ID
)
SELECT ELEC_ORDER.CUST_ID AS CUST_ID,
       ELEC_ORDER.ORDER_DATE AS ORDER_DATE,
       ELEC_ORDER.SHIP_METHOD AS SHIP_METHOD,
       ELEC_ORDER.REC_CREN_TM AS REC_CREN_TM,
       ELEC_ORDER.ORDER_ID AS ORDER_ID         -- only 5 columns but 7 in the previous part
FROM   ELEC_ORDER
WHERE  ELEC_ORDER.CUST_ID = 'CSTMR10001'
AND    ELEC_ORDER.ORDER_ID = 'ELORD10001';

无效。语法是：

INSERT INTO table_name ( column_name, column_name )
SELECT value, value FROM other_table

您似乎试图用常量/序列值替换列名，然后从SELECT语句中省略这些值。

你想要这样的东西：

INSERT INTO ELEC_ORDER_HT (
  OMS,                      -- or whatever the correct column name is
  CUST_ID,
  ORDER_DATE,
  SHIP_METHOD,
  REC_CREN_TM,
  REC_HIST_CREN_TM,
  ORDER_ID
)
SELECT OMS_SEQ.NEXTVAL,
       CUST_ID,
       ORDER_DATE,
       SHIP_METHOD,
       REC_CREN_TM,
       TIMESTAMP '2017-11-23 01.56.01.103000', -- or SYSTIMESTAMP if you want current time
       ORDER_ID
FROM   ELEC_ORDER
WHERE  CUST_ID = 'CSTMR10001'
AND    ORDER_ID = 'ELORD10001';

ORA-00917：DATE列上缺少逗号
