Class CountingFactory

  • All Implemented Interfaces:
    org.apache.calcite.sql2rel.InitializerExpressionFactory
    public class CountingFactory
extends org.apache.calcite.sql2rel.NullInitializerExpressionFactory
    To check whether InitializerExpressionFactory.newColumnDefaultValue(org.apache.calcite.plan.RelOptTable, int, org.apache.calcite.sql2rel.InitializerContext) is called.

    If a column is in defaultColumns, returns 1 as the default value.
