Question

粘贴下面的查询下面不再获取输入。这里DATE_WID是Number（10）数据类型。因为我想在2个约会之间，所以我想尝试一下。有人可以帮我吗？

SELECT     NEXT_SCHEDULE.POSITION_DH_WID,
           NEXT_SCHEDULE.ORG_WID,
           NEXT_SCHEDULE.DATE_WID,
           CONTACTED_CUSTOMERS.DATE_WID,
           NEXT_SCHEDULE.SNAPSHOT_DT,
           NEXT_SCHEDULE.SNAPSHOT_WEEK,
           NEXT_SCHEDULE.CUSTOMER_WID,
           DUE     AS FUTURE_DUE
      FROM WC_RT_CUST_DUE_2TO53WEEKS_VW NEXT_SCHEDULE,WC_RT_CUST_CONTACT_WEEKLY_VW CONTACTED_CUSTOMERS
             WHERE NEXT_SCHEDULE.CUSTOMER_WID=CONTACTED_CUSTOMERS.CUSTOMER_WID AND
             NEXT_SCHEDULE.POSITION_DH_WID=CONTACTED_CUSTOMERS.POSITION_DH_WID
             and TO_DATE(NEXT_SCHEDULE.DATE_WID,'YYYY/MM/DD') BETWEEN 
             TO_DATE(CONTACTED_CUSTOMERS.DATE_WID, 'YYYY/MM/DD')+7 and TO_DATE(NEXT_SCHEDULE.DATE_WID,'YYYY/MM/DD')
             --AND CONTACTED_CUSTOMERS.DATE_WID <>0 and NEXT_SCHEDULE.DATE_WID <>0
             GROUP BY 
             NEXT_SCHEDULE.POSITION_DH_WID,
           NEXT_SCHEDULE.ORG_WID,
           NEXT_SCHEDULE.DATE_WID,
           CONTACTED_CUSTOMERS.DATE_WID,`enter code here`
           NEXT_SCHEDULE.SNAPSHOT_DT,
           NEXT_SCHEDULE.SNAPSHOT_WEEK,
           NEXT_SCHEDULE.CUSTOMER_WID, DUE

日期转换：TO_DATE(CONTACTED_CUSTOMERS.DATE_WID, 'YYYY/MM/DD')在这里是错误的。（/不能包含在具有NUMBER数据类型的列中）

如果您的DATE_WID是数字，且格式为：“ YYYYMMDD”，则使用TO_DATE(CONTACTED_CUSTOMERS.DATE_WID, 'YYYYMMDD')并类似。

但是，将日期存储在不同的数据类型中是一种不良做法。

干杯！

ORA-01840输入值的日期格式不够长
