All Implemented Interfaces:

org.apache.calcite.plan.Context, org.apache.calcite.schema.Wrapper

Deprecated.

TODO hack code, its logical should be integrated to AggSqlFunction

@Deprecated
public class HiveAggSqlFunction
extends org.apache.flink.table.planner.functions.utils.AggSqlFunction

Hive AggSqlFunction. Override getFunction to clone function and invoke HiveUDAF#setArgumentTypesAndConstants. Override SqlReturnTypeInference to invoke HiveUDAF#getHiveResultType instead of HiveUDAF#getResultType.
