ODI 12c中使用Groovy脚本创建工程

本文主要介绍在ODI中使用groovy创建工程，并添加一个表转换的映射。要创建groovy脚本，可以从ODI Studio的菜单：工具->Groovy->新脚本 打开一个编辑窗口。在执行下面的脚本之前，确认在模型中已经有EMP表。

}
}
//创建映射结束

//执行
createProject("PRO_SCOTT","First Folder")
createMapping("PRO_SCOTT", "First Folder", "New_Mapping")

点击执行脚本，即可看到生成的工程名(PRO_SCOTT)及映射名称（New_Mapping）
