>                 Key: CALCITE-5862
>                 URL: https://issues.apache.org/jira/browse/CALCITE-5862
>             Project: Calcite
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 1.34.0
>            Reporter: Ran Tao
>            Assignee: Ran Tao
>            Priority: Major
>
> when run select array(1, 2, 'Hi')
> spark-sql (default)> select array(1, 2, 'Hi');
> ["1","2","Hi"] 
> and calcite will cause {*}java.lang.NullPointerException: inferred array element type{*}.
> Spark supports both character and numeric types in the array, and the return type is character.
> In fact, calcite also allows both character and numeric types to exist in the operand type checker, but there is no corresponding processing logic in the return type inference, so an error is reported.
> We should fix this bug.
