Hi All, I am working on a project based on Flink SQL, but found that I can`t rename column after casting, the code is as below: cast(json_type as INTEGER) as xxx And the following exception is reported: org.apache.calcite.runtime.CalciteContextException: From line 4, column 6 to line 11, column 38: Illegal mixing of types in CASE or COALESCE statement
I want to know that does Flink do not support this function because I think it is a common case? Is there a way to accomplish this function? Thank a lot. Best Henry Xu
