## Proposed changes [Issue Number: close #xxx](https://github.com/apache/doris/issues/30229) Error Reason: In the expression, time_to_sec(timediff('2024-01-22', '2024-01-15')), the two strings '2024-01-22' and '2024-01-15' are first cast to datetime types. Due to the absence of the timev2 type in the input parameters of the new optimizer for the time_to_sec function, it falls back to the old optimizer. At this point, the signature of timediff is name = "timediff", argTypes = { "DATETIME", "DATETIME" }, returnType = "TIMEV2"). This signature triggers constant folding, but the constant folding mechanism is outdated and hasn't been updated in subsequent releases. As a result, an error occurs. In contrast, time_to_sec(timediff(to_date('2024-01-22'), to_date('2024-01-15'))), due to the presence of an additional function, does not trigger the constant folding error. <!--Describe your changes.--> ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
