Java Oracle SQL PreparedStatement setdate

我正在胡思乱想，我找不到解决这个问题的好办法，我搜索了一些其他的话题，但仍然没有任何想法。我对准备好的报表有问题，特别是在确定日期方面。我知道，oracle Date需要YYYY/MM/DD格式的日期和YYYY-MM-DD格式的java.sql.Date，但这些方案都不能很好地工作

 String query = "INSERT INTO STUDENTS VALUES (?,?,?,?,?,?,?,?)";
            PreparedStatement statement = connection.prepareStatement(query);
            statement.setInt(1, Integer.parseInt(studentIndex.getText()));
            statement.setString(2, studentName.getText());
            statement.setString(3, studentLastName.getText());
            statement.setDate(4, Date.valueOf(studentDate.getText()));
            statement.setNString(5, studentSex.getText());
            statement.setString(6, studentCity.getText());
            statement.setString(7, studentMajor.getText());
            statement.setString(8, studentSpeciality.getText());
            ResultSet result = statement.executeQuery();

在JTextField中启动并编写一些示例日期后，例如1999-10-20或1999/10/20，我有一个例外

有什么想法吗

已解决

尝试使用TO_date的SQL语句显式设置日期格式，例如

String query = "INSERT INTO STUDENTS VALUES (?,?,?,TO_DATE(?,'YYYY-MM-DD'),?,?,?,?)";

---

然后确保Java变量中的日期格式匹配。如果不同，请根据需要更改TO_DATE中的格式。

不要尝试使用

DATE.valueOf

来解析日期字符串，而应该使用

DateFormat.parse

。它允许您设置一个模式来精确指定日期字符串的格式，以便正确解析。事实上，

SimpleDateFormat

便利类可能就是您所需要的。请参阅文档，不要使用“statement.setDate（4，Date.valueOf（studentDate.getText（））；”，请使用“statement.setString（4，studentDate.getText（））；”。我们让Oracle通过TO_日期进行转换，因此我们只需传入字符串。
