org.apache.drill.exec.planner.sql.DrillCalciteSqlSumEmptyIsZeroAggFunctionWrapper
All Implemented Interfaces:
org.apache.calcite.plan.Context, org.apache.calcite.schema.Wrapper, DrillCalciteSqlWrapper
public class DrillCalciteSqlSumEmptyIsZeroAggFunctionWrapper extends org.apache.calcite.sql.fun.SqlSumEmptyIsZeroAggFunction implements DrillCalciteSqlWrapper
This class serves as a wrapper class for SqlSumEmptyIsZeroAggFunction with the same goal as DrillCalciteSqlAggFunctionWrapper but extends SqlSumEmptyIsZeroAggFunction to allow using additional Calcite functionality designated for SqlSumEmptyIsZeroAggFunction.
