Francesco Guardiani commented on FLINK-26327:
---------------------------------------------
Can you share the code of the Nvl class, or even better a small self-contained
reproducer?
> throw not a literal exception in callContext.getArgumentValue when
> getTypeInference

> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 1.14.2
> Reporter: Spongebob
> Priority: Major
>
>
> {code:java}
> //代码占位符
> tableEnvironment.createTemporaryFunction("ROUNDX", RoundX.class);
> tableEnvironment.createTemporaryFunction("NVL", Nvl.class);
> tableEnvironment.executeSql("select ROUNDX( CAST(1.12345 as
> decimal(10,3)),NVL(MAX(f0),2) ) from t1").print();
> // exception
> Exception in thread "main" java.lang.AssertionError: not a literal: NVL($0, 2)
> // trace
> // `NVL` is a scalarFunction that likes oracle nvl function. And this
> exception might be thrown from this code in my `getTypeInference` function
> of ROUNDX scalarFunction.
> Optional<Integer> secondValue = callContext.getArgumentValue(1,
> Integer.class);{code}
