Quick BI数据集创建计算字段时报错aggregate function is not allowed in window,aggregate and table function arguments是什么原因? 【问题原因】 创建的计算字段使用了聚合函数,而计算字段中引用的字段也是计算字段,并且引用的计算字段也使用了聚合函数计算,由于聚合函数中不支持嵌套聚合函数的使用,所以报错了。 【解决...

When the result of this function is normalized, values having duplicate keys are discarded. In keeping with the MySQL JSON data type specification that does not permit duplicate keys, only the last value encountered is used with that key in the returned object (“last duplicate key wins”). ...
Some aggregate functions that are allowed in a query are not computed directly in an execution plan, but through a workaround. For instance, if a query uses the AVG function, the execution plan computes two values, a COUNT and a SUM, and then uses a Compute Scalar operator to compute ...
