ORA-41692: Unsupported aggregate operator in the having/compute clause: string

Cause: An attempt was made to use an unsupported aggregate operator in the having or the compute clause in the rule condition.

Action: Correct the input and try again.

ORA-41692: unsupported aggregate operator in the having/compute clause: string是指在SQL语句的having或compute子句中，出现了不被支持的聚合运算符（string）。

官方解释

常见案例

SELECT * FROM test_table

WHERE price > 50

HAVING SUM(price) > 100 AND COUNT(*) > 5

一般处理方法及步骤

1、修复SQL语句，把having或compute子句计划用聚合函数或行数函数来替换，比如可以把上面的SQL语句修复为：

SELECT * FROM test_table

WHERE price > 50

GROUP BY price

HAVING SUM(price) > 100

2、尽可能减少执行逻辑，减少运算时间。
