java连接access数据库问题


try
        {
            theStatement=theConnection.createStatement();
            theResult=theStatement.executeQuery("select * from people");
            DefaultTableModel tableModel = (DefaultTableModel) jTable1.getModel();
            tableModel.setRowCount(0);
            while(theResult.next())
            {
                String colValue[]={theResult.getString(1),gbk_str.gbk_string(theResult.getBytes(2)),gbk_str.gbk_string(theResult.getBytes(3))};
                tableModel.addRow(colValue);
            }
            jTable1.invalidate();
        }
        catch(Exception e)
        {
            handleException(e);
        }
这个是可以的String peo_name=jTextField2.getText();
        try
        {
            theStatement=theConnection.createStatement();
            theResult=theStatement.executeQuery("select * from people where name ='"+peo_name+"'");
这个就有问题了
