ResolveAggregateFunctions

object ResolveAggregateFunctions extends Rule[LogicalPlan] with AliasHelper

This rule finds aggregate expressions that are not in an aggregate operator. For example, those in a HAVING clause or ORDER BY clause. These expressions are pushed down to the underlying aggregate operator and then projected away after the original operator.

    Resolves the given expressions as if they are in the given Aggregate operator, which means the column can be resolved using agg.child and aggregate functions/grouping columns are allowed. It returns a list of named expressions that need to be appended to agg.aggregateExpressions, and the list of resolved expressions.
