我遇到了一些关于从 MS 访问数据库检索数据的问题

Question

我正在尝试从数据库中检索数据，但遇到了一些问题。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 中提供了正确的数据库路径。这是我试图从中检索数据的数据库我不知道我做错了什么。

这里是堆栈跟踪：

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

Answer 1

在你的代码中试试这个 String sql="select [Property type],[Property owner] from property where [Property type]='"+searchbyidfld.getText()+"'and [Property owner]='"+searchbynamefld.getText()+"'"; 包含空格的列名应该用正方形括起来 brackets.I 希望这对你有用
