public static class AggPrelBase.SqlSumCountAggFunction extends org.apache.calcite.sql.SqlAggFunction
Specialized aggregate function for SUMing the COUNTs. Since return type of COUNT is non-nullable and return type of SUM is nullable, this class enables creating a SUM whose return type is non-nullable.
