   ### 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 传递参数时，值中若有逗号，要求用双引号包裹逗号，如"id,code,date".

 />
   
   然而，在变量替换时，这个双引号是被保留的，会完整替换占位符内容。示例如下：
   配置文件：
   
   <img width="407" alt="Image" 
src="https://github.com/user-attachments/assets/a6e27d08-7a98-45db-8ce2-c072101fd8a2";
 />
   
   实际生成的配置：
   
   <img width="676" alt="Image" 
src="https://github.com/user-attachments/assets/75523cfc-fd1b-4d4f-a975-108fb02bb2da";
 />
   
   这种带双引号的查询语句是不能正常执行的。
   
   我的建议是：变量替换时去掉开头结尾的双引号。
