类 CountingFactory

java.lang.Object

org.apache.calcite.sql2rel.NullInitializerExpressionFactory

org.apache.calcite.test.catalog.CountingFactory

所有已实现的接口:

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.
