CloudSen opened a new issue, #14417: URL: https://github.com/apache/dolphinscheduler/issues/14417
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened If I use Oracle or DM database in SQL-TASK, and then execute select statement that contains CLOB(in Oracle) or TEXT(in DM) field, it will have serialization errors. After debugging, I found that this may be a design problem. All query results will be serialized, but not all jdbc-driver classes can be serialized. This happend at: `org/apache/dolphinscheduler/plugin/task/sql/SqlTask.java:305` ### What you expected to happen All data types should be queryable. ### How to reproduce 1. create process 2. drag SQL-TASK component 3. choose ORACLE database 4. choose QUERY sql type 5. edit select statement to query CLOB fields 6. online and execute process ### Anything else _No response_ ### Version 3.1.x ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
