錯誤插入數據庫

我有一個web形式基本上是這樣，錯誤插入數據庫

我的頁面有標籤，按鈕，GRIDVIEW，文本框

數據顯示從另一個數據庫來

每當我嘗試插入到另一個數據庫（再次）錯誤發生時說：

當使用列列表且IDENTITY_INSERT爲ON時，表'PO2'中標識列的顯式值只能爲。

我使用SQL Server

ASPNET碼：

<table class="col-lg-12"> 

    <tr>

     Shipping Method</td> 
     <td class="style6">Shipping Term</td>

這裏是BTN碼（覈准）

void addtoPO() 
    { 
     con.Open(); 
     SqlCommand cmd = new SqlCommand(); 
     cmd.Connection = con; 
     cmd.CommandText = "INSERT INTO PO2 VALUES (@UserID, @SupplierID, @CompanyName, @ShippingMethod, " + 
      "@ShippingTerm, @Term, @DeliveryDate, @ModifiedBy, @DateModified, @Status, @Remarks, @PODate, @DeliveryDate)"; 
     cmd.Parameters.AddWithValue("@UserID", Session["userid"].ToString()); 
     cmd.Parameters.AddWithValue("@SupplierID", lbSupplierID.Text); 
     cmd.Parameters.AddWithValue("@CompanyName", lbCompName.Text); 

     cmd.Parameters.AddWithValue("@ShippingMethod", lbShippingMethod.Text); 
     cmd.Parameters.AddWithValue("@ShippingTerm", lbShippingTerm.Text); 
     cmd.Parameters.AddWithValue("@Term", lbPaymentTerm.Text); 

     cmd.Parameters.AddWithValue("@ModifiedBy", lbFNA.Text + lbLNA.Text); 
     cmd.Parameters.AddWithValue("@DateModified", DateTime.Now); 
     cmd.Parameters.AddWithValue("@Status", "Approved"); 
     cmd.Parameters.AddWithValue("@Remarks", txtRemarks.Text); 

     cmd.Parameters.AddWithValue("@PODate", DateTime.Now); 
     cmd.Parameters.AddWithValue("@DeliveryDate", txtDate.Text); 
     cmd.ExecuteNonQuery(); 
     con.Close(); 
    } 
    protected void btnApprove_Click(object sender, EventArgs e) 
    { 
     addtoPO(); 

     foreach (GridViewRow row in GridView1.Rows) 
     { 

      if (row.RowType == DataControlRowType.DataRow) 
      { 


       int ProductID = int.Parse(GridView1.Rows[row.RowIndex].Cells[1].Text); 
       string ProductName = GridView1.Rows[row.RowIndex].Cells[2].Text; 
       decimal Price = decimal.Parse(GridView1.Rows[row.RowIndex].Cells[3].Text); 
       int Quantity = int.Parse(GridView1.Rows[row.RowIndex].Cells[4].Text); 
       int Amount = int.Parse(GridView1.Rows[row.RowIndex].Cells[5].Text); 

       con.Open(); 
       SqlCommand cmd = new SqlCommand(); 
       cmd.Connection = con; 
       cmd.CommandText = "INSERT INTO PODetails (ProductID, Name, Price, Quantity, Amount) " + 
        "VALUES (@ProductID, @Name, @Price, @Quantity, @Amount)"; 

       //cmd.Parameters.AddWithValue("@UserID", Session["userid"].ToString()); 
       cmd.Parameters.Add("@ProductID", SqlDbType.VarChar).Value = ProductID; 
       cmd.Parameters.Add("@Name", SqlDbType.VarChar).Value = ProductName.ToString(); 
       cmd.Parameters.Add("@Price", SqlDbType.Decimal).Value = Price; 
       cmd.Parameters.Add("@Quantity", SqlDbType.Int).Value = Quantity; 
       cmd.Parameters.Add("@Amount", SqlDbType.Int).Value = Amount; 

       cmd.ExecuteNonQuery(); 



       GridView1.EditIndex = -1; 
       GridView1.DataBind(); 

       //con.Open(); 

       //cmd.CommandText = "DELETE FROM Orders"; 
       //cmd.Parameters.Add("@RefNo", RefNo); 


       con.Close(); 

      } 
     }

我插入到兩個不同的表是wh y插入是分開的，其他值正在GET到GRIDVIEW中。

我打開和關閉身份但沒有工作。

其他插件，我有一切都很好，這只是一個有錯誤。

順便說一下，這是SQL Server而不是MySql – Steve

這根本不像* MySQL * – David

如果您明確地將值傳遞給字段，或者如錯誤說打開和關閉表的identity_insert。看看http://stackoverflow.com/a/3373070/87956 –

insert into TABLE ([column list]) 
values ([values list])

您還沒有列出插入列列表，因此服務器嘗試完成所有列「從左到右」。下一個錯誤是關於沒有足夠的值爲表列提供的值。目前它試圖將@ UserID發佈到PO2.ID，@SupplierID到PO2.UserID等等中。

非常感謝你@Ivan Starostin工作就像一個魅力！感謝您回答我的簡歷問題：D –

謝謝你回答大家真的很感激！原諒我的問題，因爲我是超級新硬代碼C＃和asp.net

我只是跟着先生@Ivan的答案斯塔羅斯京

cmd.CommandText = "INSERT INTO PO2 (UserID, SupplierID, CompanyName, ShippingMethod, " + 
      "ShippingTerm, Term, ModifiedBy, DateModified, Status, Remarks, PODate, DeliveryDate, FinalDeliveryDate, PRID) VALUES (@UserID, @SupplierID, @CompanyName, @ShippingMethod, " + 
      "@ShippingTerm, @Term, @ModifiedBy, @DateModified, @Status, @Remarks, @PODate, @DeliveryDate, @FinalDeliveryDate, @PRID)";

做了這樣的固定一些列INSERT語句和工作！
