如何连接两个表并在一个listview中显示它们？

Question

我使用列表视图有它列形式两个不同的数据库表。这里是我的代码，我努力：

try 
{ 
    String Query = "select id,Code,Description,Rate,Bottles,Supply,Empty,Amount,Received, 
     Customer_New.Opening_Date,Customer_New.Clients_Title,Customer_New.Cust_Id 
     from (Items INNER JOIN Customer_New on Customer_New.Cust_Id=Items.Cust_Id) 
       ,Customer_New"; 
    SQLiteDataAdapter dba = new SQLiteDataAdapter(Query, GlobalVars.conn); 
    DataSet testDs = new DataSet(); 
    dba.Fill(testDs, "Items"); //error 
    dba.Fill(testDs, "Customer_New"); //error 
    DataTable dt = testDs.Tables[0]; 
    this.lvcmodify.DataContext = testDs.Tables[0].DefaultView; 
    lvcmodify.ItemsSource = dt.DefaultView; 
    testDs.Dispose(); 
    dba.Dispose(); 
    dt.Dispose(); 
} 
catch (Exception ex) 
{ 
    MessageBox.Show(ex.ToString()); 
} 

有谁知道我怎么能做到在列表视图此功能？ 。

是否有可能在sqlite中将两个表合并到逻辑表中，并在db中进行任何更改，以便我可以在命令中使用该单个表：dba.Fill（testDs，“Items”）;？ 请帮我解决这个code.Thanks

寻找你的源代码后，我认为这个问题是你的SQL包括Customer_New两次

只需卸下最后Customer_New表。

try 
{ 
    Query = "select id,Code,Description,Rate,Bottles,Supply,Empty,Amount,Received, 
     Customer_New.Opening_Date,Customer_New.Clients_Title,Customer_New.Cust_Id 
     from Items INNER JOIN Customer_New on Customer_New.Cust_Id=Items.Cust_Id"; 
    dba = new SQLiteDataAdapter(Query, GlobalVars.conn); 
    testDs = new DataSet(); 
    dba.Fill(testDs, "Items"); 
... 
} 
catch (Exception ex) 
{ 
    MessageBox.Show(ex.ToString()); 
}
