我正在使用ActiveJDBC。我有一个由复合键（parentId，childId，effStartDate）组成的表。我有一个新的要求，允许更新effStartDate字段。当我尝试更新字段并保存时，它会出错。是否有适当的方法在ActiveJDBC中使用ORM或原始SQL方法更新它？
目前的做法：
mymodel.setEffStartDate(newStartDate);
mymodel.saveIt();
已更新以提供更多详细信息。这是确切的代码：
try {
ri.setEffStartDate(ld);
boolean didItSave = ri.saveIt(user);
System.out.println("here - " + didItSave);
} catch(Exception e) {
System.out.println("Exception: " + e);
}
当saveIt运行时，它不会出错。但是，它返回FALSE并且数据库中没有任何更新。所以我在之前的陈述中误用了“错误”。我应该说它只是没有做任何事情。
我们正在使用Oracle数据库。

如果此类记录（根据主键）已存在，方法Model.saveIt()会将模型属性保存到表中。如果要将主键设置为数据库中找不到的值，则此方法将在不做太多操作的情况下退出。
此外，您的代码中存在一些与JavaLite无关的问题。
更新：根据您在下面的评论，框架将更新记录，如果它不是“新”，这意味着如果PK或复合键不为空，它将假设您知道什么你正在做并期望通过主键或复合键在表中找到该记录，因此如果它们的键被设置而不是null，它将始终生成UPDATE而不是insert。因此，如果您将主键设置为表中不存在的值，则saveIt()或save()将不执行任何操作。有关详细信息，请参阅http://javalite.io/surrogate_primary_keys。
此外，您可以启用Logging以查看它生成的SQL。
