oracle11g - 多表插入另一个表的影响值

Question

我有表 - FAKE_CUST，PRE_CUST，NORMAL_CUST。根据FAKE_CUST表中存在的约束，必须将值带到PRE_CUST或NORMAL_CUST。

我正在使用以下代码：

INSERT ALL
         INTO PRE_CUST(CUST_ID, TOTAL_COST_TRANS) (SELECT DISTINCT CUST_ID,C FROM (
                    SELECT CUST_ID, SUM(COST_TRANS) OVER (PARTITION BY CUST_ID) as C FROM FAKE_CUST) WHERE C>1000)

         INTO NORMAL_CUST(CUST_ID, TOTAL_COST_TRANS) (SELECT DISTINCT CUST_ID,C FROM (
                    SELECT CUST_ID, SUM(COST_TRANS) OVER (PARTITION BY CUST_ID) as C FROM FAKE_CUST) WHERE C<1000)
SELECT 1 FROM DUAL;

Answer 1

您用于多表插入的语法一开始就不正确。

WHEN评估插入条件的子句必须在子句之前insert_into。

您的查询应如下所示：

INSERT ALL
   WHEN c > 1000 THEN
      INTO pre_cust (cust_id, total_cost_trans)
   WHEN c < 1000 THEN
      INTO normal_cust (cust_id, total_cost_trans)
   SELECT CUST_ID, SUM(COST_TRANS) OVER (PARTITION BY CUST_ID) as C 
   FROM   FAKE_CUST
