附近有語法錯誤Ordertb「

Question

我想刷新和更新GridView的所以我用showData（）這樣的：

protected void ShowData() 
{ 
    con.Open(); 
    string qu = string.Format("SELECT * Ordertb", con); 
    SqlDataAdapter da = new SqlDataAdapter(qu, con); 
    DataSet ds = new DataSet(); 
    da.Fill(ds, "ordertbl"); 
    if (ds.Tables["ordertbl"].Rows.Count > 0) 
    { 
     GridView1.DataSource = ds.Tables[0]; 
     GridView1.DataSourceID = null; 
     GridView1.DataBind(); 
    } 
    con.Close(); 
} 

，但我得到這個錯誤：

Incorrect syntax near 'Ordertb'. 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near 'Ordertb'.

string qu = string.Format("SELECT * FROM Ordertb", con); 

Answer 2

試試這個SQL查詢：

Select * From Ordertb 

在您的代碼：
