All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`RelBuilder.AggCall`	`approximate(boolean approximate)` Returns a copy of this AggCall that may return approximate results if `approximate` is true.
`RelBuilder.AggCall`	`as(@Nullable String alias)` Returns a copy of this AggCall with a given alias.
`default RelBuilder.AggCall`	`distinct()` Returns a copy of this AggCall that is distinct.
`RelBuilder.AggCall`	`distinct(boolean distinct)` Returns a copy of this AggCall that is optionally distinct.
`RelBuilder.AggCall`	`filter(@Nullable RexNode condition)` Returns a copy of this AggCall that applies a filter before aggregating values.
`RelBuilder.AggCall`	`ignoreNulls(boolean ignoreNulls)` Returns a copy of this AggCall that ignores nulls.
`RelBuilder.OverCall`	`over()` Converts this aggregate call to a windowed aggregate call.
`RelBuilder.AggCall`	`sort(Iterable<RexNode> orderKeys)` Returns a copy of this AggCall that sorts its input values by `orderKeys` before aggregating, as in SQL's `WITHIN GROUP` clause.
`default RelBuilder.AggCall`	`sort(RexNode... orderKeys)` Returns a copy of this AggCall that sorts its input values by `orderKeys` before aggregating, as in SQL's `WITHIN GROUP` clause.
`RelBuilder.AggCall`	`unique(@Nullable Iterable<RexNode> distinctKeys)` Returns a copy of this AggCall that makes its input values unique by `distinctKeys` before aggregating, as in SQL's `WITHIN DISTINCT` clause.
`default RelBuilder.AggCall`	`unique(RexNode... distinctKeys)` Returns a copy of this AggCall that makes its input values unique by `distinctKeys` before aggregating, as in SQL's `WITHIN DISTINCT` clause.
