Class FlinkCurrentDateDynamicFunction

  • @Internal
public class FlinkCurrentDateDynamicFunction
extends org.apache.calcite.sql.fun.SqlCurrentDateFunction
    The Flink CURRENT_DATE function differs from the parent SqlCurrentDateFunction which is aware of whether it is used in batch mode, if true it will act totally same as the parent SqlCurrentDateFunction, but will be a non-deterministic function if not in batch mode.
