我有我的項目,它是一個駕駛執照數據庫。java.sql.SQLException:參數索引超出範圍(1>參數數量,爲0)ERROR
當用戶填寫字段時,這是正常的,但是當用戶按下「提交」按鈕時,一切都搞亂了。
The error Parameter index out of range
錯誤顯示,所以這是我的代碼。
private void submitButtonActionPerformed(java.awt.event.ActionEvent evt) {
String sql = "INSERT INTO dr_record_table (Driver's ID, Last Name, First Name, Middle Name, Street, Barangay, City/Municipality, Province, Country, Month, Day, Year, Gender) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
try {
pst = conn.prepareStatement(sql);
pst.setString(1, idTxtFld.getText());
pst.setString(2, lnTxtFld.getText());
pst.setString(3, fnTxtFld.getText());
pst.setString(4, mnTxtFld.getText());
pst.setString(5, saTxtFld.getText());
pst.setString(6, baTxtFld.getText());
pst.setString(7, caTxtFld.getText());
pst.setString(8, paTxtFld.getText());
pst.setString(9, cntryTxtFld.getText());
pst.setString(10, String.valueOf(monthCBox.getSelectedItem()));
pst.setString(11, String.valueOf(dayCBox.getSelectedItem()));
pst.setString(12, String.valueOf(yearCBox.getSelectedItem()));
pst.setString(13, getSelectedButtonText(bg));
pst.execute();
JOptionPane.showMessageDialog(null, "Entry Saved!");
} catch (SQLException | HeadlessException e) {
JOptionPane.showMessageDialog(null, e);
}
}
謝謝先生!我終於修好了這個! :) –
