> Project: Calcite
> Issue Type: Bug
> Reporter: Feng Jin
> Assignee: Feng Jin
> Priority: Major
>
> Currently, when using named parameters, there may be some issues due to the
> incorrect expansion of named parameters during validation. Specifically,
> several unit tests can be added to reproduce this.
> add a test case
> org.apache.calcite.test.UdfTest#testScalarFunctionWithParameter
> {code:java}
> @Test void testScalarFunctionWithParameter() {
> final String sql = "select \"adhoc\".my_det_plus(X => \"deptno\", Y =>
> 100) as p\n"
> + "from \"adhoc\".EMPLOYEES";
> final AtomicInteger c =
> Smalls.MyDeterministicPlusFunction.INSTANCE_COUNT.get();
> final int before = c.get();
> withUdf().query(sql).returnsUnordered("P=110",
> "P=120",
> "P=110",
> "P=110");
> final int after = c.get();
> assertThat(after, is(before + 1));
> }
> {code}
> And we will get the following error：
> {code:java}
