如何列出其會員需要續約的會員姓名和地址？

Question

我得到這個錯誤訊息 '缺少右括號' 作爲使用下面的SQL查詢：

SELECT G_MEMBERSHIP.MEMBER_ID, DATE_ADD(G_MEMBERSHIP.RENEWAL_DATE,INTERVAL 1 YEAR) WHERE G_MEMBERSHIP.RENEWAL_DATE > CURDATE() 
FROM G_MEMBERSHIP 
INNER JOIN G_MEMBER 
ON G_MEMBERSHIP.MEMBER_ID = G_MEMBER.MEMBER_ID 

Answer 1

SELECT G_MEMBERSHIP.MEMBER_ID,add_months(G_MEMBERSHIP.RENEWAL_DATE,12) 
FROM G_MEMBERSHIP 
INNER JOIN G_MEMBER 
ON G_MEMBERSHIP.MEMBER_ID = G_MEMBER.MEMBER_ID 
WHERE G_MEMBERSHIP.RENEWAL_DATE > current_date 

---

附：

+ INTERVAL '1'是有風險的

例如

select date '2012-02-29' + INTERVAL '1' YEAR from dual; 

ORA-01839：日期無效月指定

select add_months (date '2012-02-29',12) from dual

Answer 2

WHERE走後JOIN

SELECT G_MEMBERSHIP.MEMBER_ID, DATE_ADD(G_MEMBERSHIP.RENEWAL_DATE,INTERVAL 1 YEAR) 
FROM G_MEMBERSHIP 
INNER JOIN G_MEMBER 
    ON G_MEMBERSHIP.MEMBER_ID = G_MEMBER.MEMBER_ID 
WHERE G_MEMBERSHIP.RENEWAL_DATE > CURDATE()
