Skipped()

Sentinel: the builder declines to produce SQL because an arg/item/value couldn't be translated AND the surrounding visitor is in Expression mode AND the aggregate config has IsServerSideOnly set to false. Build(ITranslationContext, MethodCallExpression, bool) returns null so the dispatch chain cascades to the surrounding partial-translation fallback.

public static BuildAggregationFunctionResult Skipped()

Returns

BuildAggregationFunctionResult
