我正在拉我的頭髮，我找不到好的解決方案，我搜索了一些其他主題，但仍然沒有任何想法。 PreparedStatement有問題，尤其是設置日期。我知道，在YYYY-MM-DD中，Date需要日期格式爲YYYY/MM/DD和java.sql.date，但是這些方案中的任何一個都不能正常工作。Oracle SQL PreparedStatement setdate
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中啓動並寫入一些示例日期後，例如， 1999-10-20 or 1999/10/20我有個例外

有什麼建議嗎？

不幸的是不起作用。與YYYY/MM/DD相同。 – 1kka
不要使用「statement.setDate（4，Date.valueOf（studentDate.getText（）））;」，使用「statement.setString（4，studentDate.getText（））;」。我們讓Oracle通過TO_DATE執行轉換，所以我們只傳入字符串。 – TenG
解決了，謝謝 – 1kka
