根据是否存在外键使用 scriptella 复制数据

Question

我正在尝试将数据从一个 table 复制到另一个，但在这样做之前，我需要检查所选的代码文章是否已经作为键存在于另一个 table.So 我会复制它们，如果存在，我不会复制它们，如果不存在，我会记录它们在这里我做了任何帮助来测试是否存在选定的代码文章。

这是我所做的

                Object objGold =get("CODEART");
                Object objLocal =get("id");
                if(objGold.equals(objLocal))
                {

                System.out.println("equals);

                result=true ;}
                else{
                System.out.println("not equal");

                result=false ;
                }
                set("result", result);
                next();


                <script connection-id="out" if="result">

                </script>

根据是否存在外键使用 scriptella 复制数据
