> Key: FLINK-16181
> URL: https://issues.apache.org/jira/browse/FLINK-16181
> Project: Flink
> Issue Type: Bug
> Reporter: Benchao Li
> Priority: Major
>
> It can be reproduced by a simple test case:
> Add below to {{ScalarOperatorsTest}}
> {code:java}
> testSqlApi("IF(true, CAST('non-numeric' AS BIGINT), 0)", "null")
> {code}
>
> IMO, it's {{IfCallGen}}'s bug, which should judge the nullTerm of operands
> first before assignment.
