### 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 NullPointerException happened when running sql task, with both ? and customer parameter in sql. E.g. `select '${mode}', '?'` ` [INFO] 2023-07-07 23:51:17.551 +0000 - setSqlParamsMap: Property with paramName: mode put in sqlParamsMap of content select '${mode}', '?' successfully. [ERROR] 2023-07-07 23:51:17.551 +0000 - sql task error java.lang.NullPointerException: null [ERROR] 2023-07-07 23:51:17.551 +0000 - Task execute failed, due to meet an exception org.apache.dolphinscheduler.plugin.task.api.TaskException: Execute sql task failed at org.apache.dolphinscheduler.plugin.task.sql.SqlTask.handle(SqlTask.java:168) at org.apache.dolphinscheduler.server.worker.runner.DefaultWorkerDelayTaskExecuteRunnable.executeTask(DefaultWorkerDelayTaskExecuteRunnable.java:49) ` ### What you expected to happen No Exception should happen. ### How to reproduce Create a SQL Task, use the sql `select '${mode}', '?'` And run the task. ### Anything else My environment is 3.1.4. After code investigate, the suspicious code is here: https://github.com/apache/dolphinscheduler/blob/a1bf597d0a348f67a3e943217dcf700e484ac9f8/dolphinscheduler-task-plugin/dolphinscheduler-task-api/src/main/java/org/apache/dolphinscheduler/plugin/task/api/utils/ParameterUtils.java#L195 ` String[] split = sql.split("\\?");` Seems assuming any ? in sql is parameter holder, which is not true. ### 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.
