我正在使用 ActiveJDBC。我有一个由复合键（parentId、childId、effStartDate）组成的表。我有一个允许更新 effStartDate 字段的新要求。当我尝试更新字段并保存时，它会出错。是否有合适的方法使用 ORM 或 ActiveJDBC 中的原始 SQL 方法来更新它？
目前的做法：
mymodel.setEffStartDate(newStartDate);
mymodel.saveIt();
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。所以我在之前的声明中误用了“错误”。我应该说它什么也没做。
我们正在使用 Oracle 数据库。
