我收到一些有关从ms访问数据库中检索数据的问题

Question

我正在尝试从数据库中检索数据，但我遇到了一些问题。 这是我的代码：

  {
        try
         {
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://F:\\Realestate\\real estate.accdb");
Statement st=conn.createStatement();
String sql="select Property type,Property owner from property where Property type='"+searchbyidfld.getText()+"'and Property owner='"+searchbynamefld.getText()+"'";
ResultSet rs=st.executeQuery(sql);
if(rs.next())
{
  String retrieve=rs.getString("Property type");
  System.out.println(retrieve);
 }
  }
catch(Exception ex)
 {
   JOptionPane.showMessageDialog(null,"No record found");                                           
   }
   }

我还在URL中提供了数据库的正确路径。 这是我试图检索数据的数据库 我不知道我做错了什么。

这是堆栈跟踪：

net.ucanaccess.jdbc.UcanaccessSQLException: UCAExc:::3.0.6 user lacks privilege or object not found: PROPERTY

Answer 1

在您的代码String sql="select [Property type],[Property owner] from property where [Property type]='"+searchbyidfld.getText()+"'and [Property owner]='"+searchbynamefld.getText()+"'";中尝试此操作 包含空格的列名应该用方括号括起来。我希望这对你来说很好用
