Question

我收到此错误消息＆＃39;缺少右括号＆＃39;使用以下sql查询：

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

WHERE在JOIN

之后

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()

Answer 2

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

P.S。

+ INTERVAL '1'存在风险

e.g。

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

ORA-01839：日期对指定的月份无效

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

2013-02-28 00:00:00
