                 Key: FLINK-33541
                 URL: https://issues.apache.org/jira/browse/FLINK-33541
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API

The minimum produce steps:

Flink SQL> select if(1=1, rand_integer(100), 0);
[ERROR] Could not execute SQL statement. Reason:
java.lang.Exception: Unsupported operand types: IF(boolean, INT, INT NOT NULL)

 

But we do not see the exception reported in 1.14, not sure which version this bug was introduced.
