toRule

default AggregateExpandWithinDistinctRule toRule()

Description copied from interface: RelRule.Config

Creates a rule that uses this configuration. Sub-class must override.

Specified by:

toRule in interface RelRule.Config

throwIfNotUnique

@Default
default boolean throwIfNotUnique()

Whether the code generated by the rule should throw if the arguments are not functionally dependent.

For example, if implementing SUM(sal) WITHIN DISTINCT job) ... GROUP BY deptno, suppose that within department 10, (job, sal) has the values ('CLERK', 100), ('CLERK', 120), ('MANAGER', 150), ('MANAGER', 150). If throwIfNotUnique is true, the query would throw because of the values [100, 120]; if false, the query would sum the distinct values [100, 120, 150].

withThrowIfNotUnique

AggregateExpandWithinDistinctRule.Config withThrowIfNotUnique(boolean throwIfNotUnique)

Sets throwIfNotUnique().
