我从 Oracle ADF和JDeveloper 开始。我先做一些基础教程。
从HR数据库架构,我正在尝试此练习:创建一个新位置,但在CountryId属性中,显示所有国家/地区列表。
这更加用户友好,因此用户可以选择意大利而不是输入IT。
为此,我正在做这个步骤:
在位置视图中,选择 CountryId 属性并创建LOV。这个必须从 CountriesView1 读取,其值为 CountryId ,并显示 CountryName 属性。
运行此页面时,我会看到所有国家/地区名称,但是当我选择其中一个时,它不会将其显示为已选中,并且在提交新数据时,CountryId将插入空值。
显然,我正在以错误的方式做事。 如何使用CountryId作为列表来执行此简单表单?
有人可以帮助我吗?
提前致谢。最好的问候

答案 0 :(得分:0)
好吧,我做到了! 步骤是:
最后,列出了COUNTRIES表中的所有国家/地区,并将数据插入LOCATIONS表中。
我希望这会有用。 此致
