问题补充: 执行计划如下: UPDATE STATEMENT, GOAL = ALL_ROWS 55 651 48825 UPDATE CIS NEW_QPS_PROJECT_FEE_DETAIL HASH JOIN RIGHT SEMI 55 651 48825 TABLE ACCESS FULL CIS NEW_QPS_FEECODE 3 569 6259 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_DETAIL 52 651 41664 SORT AGGREGATE 1 27 FILTER HASH JOIN OUTER 23 26 702 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_SUB 19 1 13 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_EXCHANGE_RATE 3 90 1260 SORT AGGREGATE 1 25 FILTER HASH JOIN OUTER 23 26 650 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_SUB 19 1 11 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_EXCHANGE_RATE 3 90 1260 SORT AGGREGATE 1 26 FILTER HASH JOIN OUTER 23 26 676 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_SUB 19 1 12 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_EXCHANGE_RATE 3 90 1260 SORT AGGREGATE 1 29 FILTER HASH JOIN OUTER 23 26 754 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_SUB 19 1 15 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_EXCHANGE_RATE 3 90 1260 SORT AGGREGATE 1 29 FILTER HASH JOIN OUTER 23 26 754 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_SUB 19 1 15 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_EXCHANGE_RATE 3 90 1260 SORT AGGREGATE 1 29 FILTER HASH JOIN OUTER 23 26 754 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_SUB 19 1 15 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_EXCHANGE_RATE 3 90 1260 SORT AGGREGATE 1 25 FILTER HASH JOIN OUTER 23 26 650 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_SUB 19 1 11 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_EXCHANGE_RATE 3 90 1260 SORT AGGREGATE 1 25 FILTER HASH JOIN OUTER 23 26 650 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_FEE_SUB 19 1 11 TABLE ACCESS FULL CIS NEW_QPS_PROJECT_EXCHANGE_RATE 3 90 1260

头晕,发现都是取一个联合查询的最大值,你可以自定义一个函数,将最大值取出来,然后再分割字符串,取出最大值,来更新

太头痛了,这个你可以先了解这一段代码是干嘛用的,自己重构一遍,不要看现有的了,根据需求自己写!

先把所有的要更新的数据SELECT一个TABLE,之后再用TABLE与UPDATE—TABLE进行关联更新吧,感觉会高点,最少不会UPDATE每个字段就统计一次数据。
