Question

我想添加一条新记录来访问数据库，但是SQL查询没有应用它，这里是我的代码，我在其中添加数据!!

    public void actionPerformed(ActionEvent e) {
    JButton b=(JButton)e.getSource();
    if(b==c.t.addR){
        String aa=Integer.toString(55);
        String t=c.t.titlefield.getText();
        String d=c.t.datefield.getText();
        String p=c.t.progressfield.getText();
        String pr=c.t.priorityfield.getText();
        String s="Open";
        System.out.println(t+"\t"+d+"\t"+p+"\t"+pr+"\t"+s); //error is here
        try {
            c.b.st.executeQuery("INSERT into Records (TaskID,Title,Deadline,Progress,Priority,Status) VALUES("+aa+"','"+t+"','"+d+"','"+p+"','"+pr+"','"+s+")");
        } catch (SQLException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
    }

这是我得到的错误

java.sql.SQLException：[Microsoft] [ODBC Microsoft Access驱动程序] 查询表达式中的语法错误（缺少运算符） '55'， 'A'， '1'， '1'， '高'， '打开'。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.SQLExecDirect（未知来源）at at sun.jdbc.odbc.JdbcOdbcStatement.execute（未知来源）at sun.jdbc.odbc.JdbcOdbcStatement.executeQuery（未知来源）at Listener.actionPerformed（Listener.java:27）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.AWTEventMulticaster.mouseReleased（未知来源）在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 $ 400（未知来源）at java.awt.EventQueue $ 2.run（未知来源）at java.awt.EventQueue $ 2.run（未知来源）at java.security.AccessController.doPrivileged（Native Method）at java.security.AccessControlContext $ 1.doIntersectionPrivilege（未知来源）at java.security.AccessControlContext $ 1.doIntersectionPrivilege（未知来自）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.AccessControlContext $ 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

错误必须发生在这一行：

c.b.st.executeQuery("INSERT into Records (TaskID,Title,Deadline,Progress,Priority,Status) VALUES("+aa+"','"+t+"','"+d+"','"+p+"','"+pr+"','"+s+")");

看着它，那是因为你没有围绕参数的开放和结束报价？尝试：

c.b.st.executeQuery("INSERT into Records (TaskID,Title,Deadline,Progress,Priority,Status) VALUES('"+aa+"','"+t+"','"+d+"','"+p+"','"+pr+"','"+s+"')");

使用java和SQL查询INSERT INTO将新记录插入MS访问
