java 无法在 sql 数据库中写入数据，但读取成功

Question

我正在使用下面的代码：

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 Driver][SQL Server]Incorrect syntax near the keyword 'check'. at sun.jdbc.odbc.JdbcOdbc.createSQLException(Unknown Source) at sun.jdbc.odbc.JdbcOdbc.standardError(Unknown Source) at sun.jdbc.odbc.JdbcOdbc.SQLExecute(Unknown Source) at sun.jdbc.odbc.JdbcOdbcPreparedStatement.execute(Unknown Source) at AdminPanel.actionPerformed(AdminPanel.java:184) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.awt.EventQueue.access0(Unknown Source) at java.awt.EventQueue.run(Unknown Source) at java.awt.EventQueue.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain.doIntersectionPrivilege(Unknown Source) at java.security.ProtectionDomain.doIntersectionPrivilege(Unknown Source) at java.awt.EventQueue.run(Unknown Source) at java.awt.EventQueue.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain.doIntersectionPrivilege(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run (Unknown Source)

Answer 1

'check' 是保留关键字，因此代码失败，尝试使用不是关键字的名称应该可以解决问题。
