### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened i have a task source from mysql, sink to maxcompute, with field mapper, i find sink columns in maxcompute is out of order env { job.mode = BATCH } source { Jdbc{ password = "" driver = "com.mysql.cj.jdbc.Driver" query = "SELECT id,uid,user_name,job_name,params,created_at,updated_at FROM lakeservice_task" partition_column = "id" user = "" url = "" partition_num = "4" } } transform { FieldMapper { field_mapper = { id = id uid = uid user_name = user_name job_name = job_name params = params created_at = created_at updated_at = updated_at } } } sink { Maxcompute{ accessId = "" endpoint = "" accesskey = "" project = "dp_ads_app_ecube_sec_sit_dev" table_name = "lake_service_07" } } after job finished, i select all records from maxcompute:  Two problems: 1. All column values are written incorrectly: the uid column writes the value of the params column; the updated_at column writes the value of the id column... 2. `id` column is a bigdecimal field, but '\N' is wroten。 ### SeaTunnel Version 2.3.3 ### SeaTunnel Config ```conf env { job.mode = BATCH } source { Jdbc{ password = "" driver = "com.mysql.cj.jdbc.Driver" query = "SELECT id,uid,user_name,job_name,params,created_at,updated_at FROM lakeservice_task" partition_column = "id" user = "" url = "" partition_num = "4" } } transform { FieldMapper { field_mapper = { id = id uid = uid user_name = user_name job_name = job_name params = params created_at = created_at updated_at = updated_at } } } sink { Maxcompute{ accessId = "" endpoint = "" accesskey = "" project = "dp_ads_app_ecube_sec_sit_dev" table_name = "lake_service_07" } } ``` ### Running Command ```shell i use dolphinscheduler ``` ### Error Exception ```log see 'What happened' chapter ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version _No response_ ### Screenshots _No response_ ### Are you willing to submit PR? - [X] 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.
