使用带有ON子句的SQL的案例-Netezza

Question

请输入以下代码

SELECT DISTINCT 
CASE WHEN LENGTH (i.MOBILE_NUMBER) = 10 THEN 0||i.MOBILE_NUMBER ELSE i.MOBILE_NUMBER END AS New_Mob_Num,
COUNT(i.SUBS_ID) AS Subs_Count,
COUNT(s.MESSAGEID) AS SMS_COUNT,
              SUM(CASE WHEN s.MESSAGESTATE = 'Undeliverable' THEN COUNT ELSE 0 END) AS Undeliverablecount,
              SUM(CASE WHEN s.MESSAGESTATE = 'Delivered' THEN COUNT ELSE 0 END) AS Deliveredcount
    FROM PRD_STG.MOB.INF_SUBSCRIBER i
    INNER JOIN ANALYTICS.sms.mq s 
ON i.New_Mob_Num = strright(s.destination, 11)
GROUP BY 1

我收到一个错误ERROR: Attribute 'I.NEW_MOB_NUM' not found

谁可以使用列[和带有[[Joining的ON子句。 并且当使用CASE WHEN语句和下面的ON子句时，我得到了错误的结果

SELECT DISTINCT 
CASE WHEN LENGTH (i.MOBILE_NUMBER) = 10 THEN 0||i.MOBILE_NUMBER ELSE i.MOBILE_NUMBER END AS New_Mob_Num,
COUNT(i.SUBS_ID) AS Subs_Count,
COUNT(s.MESSAGEID) AS SMS_COUNT,
              SUM(CASE WHEN s.MESSAGESTATE = 'Undeliverable' THEN COUNT ELSE 0 END) AS Undeliverablecount,
              SUM(CASE WHEN s.MESSAGESTATE = 'Delivered' THEN COUNT ELSE 0 END) AS Deliveredcount
    FROM PRD_STG.MOB.INF_SUBSCRIBER i
    INNER JOIN ANALYTICS.sms.mq s 
ON (CASE WHEN LENGTH (i.MOBILE_NUMBER) = 10 THEN 0||i.MOBILE_NUMBER ELSE i.MOBILE_NUMBER END) 
= strright(s.destination, 11)
GROUP BY 1

请输入以下代码，当长度（i.MOBILE_NUMBER）= 10 THEN时选择不同的情况0 || i.MOBILE_NUMBER ELSE i.MOBILE_NUMBER END AS New_Mob_Num，COUNT（i.SUBS_ID）AS Subs_Count，COUNT（s ... 。
