oracle update set 多个字段

Posted 2023-02-22

UPDATE M_VEH_CHARGE_REAL SET ( CHARGE_TIME ,YGZDD , POWER_STATION_NO , WHETHER_BATTERY , VOLT , CUR) =
(select CHAGE_TIME , YGZDD, POWER_STATION_NO, WHETHER_BATTERY, VOLT, CUR from ( select rownum rn, t.* from M_CHARGEPOLE_REAL t where CHARGEPOLE_NO in
(select EQUIP_NO from D_STAKE_ARCH order by CHARGEPOLE_NO where STAKE_PARA_ID = '3') )B , ( select rownum rn , z.EQUIP_NO from D_CHG_ENG_ARCH z order by EQUIP_NO where CHG_ENG_PARA_ID = '7' )C
where B.rn = C.rn and M_VEH_CHARGE_REAL.CHARGE_NO = C.EQUIP_NO)
WHERE EXISTS ( SELECT 1 FROM ( from (select rownum rn, t.* from M_CHARGEPOLE_REAL t where CHARGEPOLE_NO in
(select EQUIP_NO from D_STAKE_ARCH where STAKE_PARA_ID = '3') order by CHARGEPOLE_NO )B , ( select rownum rn , z.EQUIP_NO from D_CHG_ENG_ARCH z where CHG_ENG_PARA_ID = '7' order by EQUIP_NO)C
where B.rn = C.rn and M_VEH_CHARGE_REAL.CHARGE_NO = C.EQUIP_NO)
错误信息:ora-00907:missing right parenthesis
思路: 表B的数据更新A表数据(A表的id = C表 id )

WHERE EXISTS ( SELECT 1 FROM ( from (select rownum rn, t.* from M_CHARGEPOLE_REAL t

那行多了 from （

WHERE EXISTS ( SELECT 1 FROM （select rownum rn, t.* from M_CHARGEPOLE_REAL t
一个sql都一天了还没搞定 有问题私聊我追问

不好意思 那是往这上面写的时候多写的之前并没有 ...
还是 ORA-00907 :missing right parenthesis

后面的select 列名from ...where b.rn=c.rn 之间是正确的 在pl/sql里可以查询出结果

参考技术A 就是你结尾少了一个右括号追问

并没有发现少括号
