java - 使用 ResultSet 返回最后生成的键

Question

我正在尝试执行插入语句并在执行后获取生成的 ID。到目前为止，我已经进行了查询和准备好的语句。这是代码的一部分:PreparedStatement preparedStatement = connetion.prepareStatement(query.toString(), new String[] {"id"});添加所有参数后，我执行此操作:

preparedStatement.executeUpdate();
ResultSet resultSet = preparedStatement.getGeneratedKeys();
resultSet.next();
resultSet.getLong(1);

它抛出的异常是这样的:

java.sql.SQLException: Invalid argument(s) in call

一个非常重要的事实是，该代码在 ojdbc7 上运行良好，但是一旦我将其切换为在 ojdbc8 上运行，就会出现此错误。任何帮助将不胜感激。

显然 prepareStatement(query.toString(), new String[] {"id"}); 方法不再适用于 oracle 数据库。经过长时间的摸索，我发现方法 prepareStatement(query.toString(), new int[] {1}); 工作正常。问题是你在 oracle 中使用它时需要小心，它以 1 而不是 0 开头，如果你输入 0 它将再次抛出错误参数的异常。
