QSM-02138: agg(expr) requires correspondng agg(expr*expr) function

QSM-02138: agg(expr) requires correspondng agg(expr*expr) function
Cause: The capability in question is not supported when the materialized view uses certain aggregate functions but omits an invocation of that same aggregate function on the square of the same argument.
Action: Add an invocation of the same aggregate function on the square of the same argument (that is, the argument multiplied by itself).

QSM-02138:agg(expr)需要对应的agg(expr * expr)函数,
.原因:当实例化视图使用某些聚合函数但省略在同一参数的平方上调用同一聚合函数时,不支持该问题的能力。,
.操作:在相同参数的平方(即自身与其自身相乘)上添加相同聚合函数的调用。,
