廣東話使用附近「）」正確的語法手冊似乎解決這個錯誤：

protected void Page_Load(object sender, EventArgs e) 
{ 
    if (Page.IsPostBack) 
    { 
     //It is a postback so check if it was by div click (NOT WORKING because the javascript isnt posting back) 
     string target = Request["__EVENTTARGET"]; 
     if (target == "DivClicked") 
     { 
      string id = Request["__EVENTARGUMENT"]; 
      //Call my delete function passing record id 
      using (OdbcConnection cn = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver}; Server=localhost; Database=gymwebsite2; User=root; Password=commando;")) 
      { 
       cn.Open(); 
       using (OdbcCommand cmd = new OdbcCommand("DELETE FROM WallPosting WHERE idWallPosting="+id+")", cn)) 
       { 
        cmd.ExecuteNonQuery(); 
       } 
      } 

     } 
    } 
    string theUserId = Session["UserID"].ToString(); 
    PopulateWallPosts(theUserId); 
} 

Answer 1

你不需要關閉)爲刪除。

using (OdbcCommand cmd = new OdbcCommand("DELETE FROM WallPosting WHERE idWallPosting=" + id, cn)) 
{ 
    cmd.ExecuteNonQuery(); 
} 

Answer 2

這是因爲你有一個額外的右括號

new OdbcCommand("DELETE FROM WallPosting WHERE idWallPosting="+id+")", cn)) 

嘗試

new OdbcCommand("DELETE FROM WallPosting WHERE idWallPosting="+id, cn)) 

Answer 3

using (OdbcCommand cmd = new OdbcCommand("DELETE FROM WallPosting WHERE idWallPosting="+id, cn)) 

，應該是它，你有一個額外的支架

Answer 4

您要關閉一個)的時候你以前沒有打開過(。 這應該可以解決問題。
