Question

我使用以下代码：

JButton btnEdit = new JButton("Edit");
btnEdit.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {

        try{
        String query = "Insert Into check(Name, Password)Values(?,?)";
        PreparedStatement pst = con.prepareStatement(query);
        pst.setString(1, textField.getText());
        pst.setString(2, textField_1.getText());
/*      pst.setString(3, textField_2.getText());
        pst.setString(4, textField_4.getText());
        pst.setString(5, textField_5.getText());
        */

        pst.execute();
        JOptionPane.showMessageDialog(null, "Data Saved");
        pst.close();
        }catch(Exception e){
            e.printStackTrace();
        }
    }
});

我正在从SQL数据库中检索数据，但每当我尝试插入数据时，我都会在运行时遇到错误：

java.sql.SQLException：[Microsoft] [ODBC SQL Server驱动程序] [SQL 服务器]关键字＆＃39; check＆＃39;附近的语法不正确。在 sun.jdbc.odbc.JdbcOdbc.createSQLException（未知来源）at at sun.jdbc.odbc.JdbcOdbc.standardError（未知来源）at sun.jdbc.odbc.JdbcOdbc.SQLExecute（未知来源）at sun.jdbc.odbc.JdbcOdbcPreparedStatement.execute（未知来源）at at AdminPanel $ 2.actionPerformed（AdminPanel.java:184）at javax.swing.AbstractButton.fireActionPerformed（未知来源）at javax.swing.AbstractButton $ Handler.actionPerformed（Unknown Source）at javax.swing.DefaultButtonModel.fireActionPerformed（未知来源）at javax.swing.DefaultButtonModel.setPressed（未知来源）at javax.swing.plaf.basic.BasicButtonListener.mouseReleased（未知来自）java.awt.Component.processMouseEvent（未知来源）at javax.swing.JComponent.processMouseEvent（未知来源）at java.awt.Component.processEvent（未知来源）at java.awt.Container.processEvent（未知来源）at java.awt.Component.dispatchEventImpl（未知来源）at java.awt.Container.dispatchEventImpl（未知来源）at java.awt.Component.dispatchEvent（未知来源）at java.awt.LightweightDispatcher.retargetMouseEvent（未知来源）at java.awt.LightweightDispatcher.processMouseEvent（未知来源）at java.awt.LightweightDispatcher.dispatchEvent（未知来源）at java.awt.Container.dispatchEventImpl（未知来源）at java.awt.Window.dispatchEventImpl（未知来源）at java.awt.Component.dispatchEvent（未知来源）at java.awt.EventQueue.dispatchEventImpl（未知来源）at java.awt.EventQueue.access $ 300（未知来源）at java.awt.EventQueue $ 3.run（未知来源）at java.awt.EventQueue $ 3.run（未知来源）at java.security.AccessController.doPrivileged（Native Method）at java.security.ProtectionDomain $ 1.doIntersectionPrivilege（未知来源）at java.security.ProtectionDomain $ 1.doIntersectionPrivilege（未知来自）java.awt.EventQueue $ 4.run（未知来源）at java.awt.EventQueue $ 4.run（未知来源）at java.security.AccessController.doPrivileged（Native Method）at java.security.ProtectionDomain $ 1.doIntersectionPrivilege（未知来自）java.awt.EventQueue.dispatchEvent（未知来源）at java.awt.EventDispatchThread.pumpOneEventForFilters（未知来源） at java.awt.EventDispatchThread.pumpEventsForFilter（Unknown Source）在java.awt.EventDispatchThread.pumpEventsForHierarchy（未知来自java.awt.EventDispatchThread.pumpEvents（未知来源） at java.awt.EventDispatchThread.pumpEvents（Unknown Source）at java.awt.EventDispatchThread.run（未知来源）

Answer 1

＆＃39;检查＆＃39;是一个保留的关键字，因此代码失败，尝试使用不是关键字的名称可以解决问题。
