複選框不發送檢查值訪問數據庫C＃Asp

Question

這是我的C＃代碼和我的問題作爲標題說是我的複選框值不會進入我的訪問數據庫，或至少不會改變它們。

     lbl5.Text = "Major"; 
    } 

    protected void c2_SelectedIndexChanged(object sender, EventArgs e) 
    { 
    } 

    protected void c1_CheckedChanged(object sender, EventArgs e) 
    { 
    } 
} 

我的數據庫看起來像這樣

Answer 1

如果要追加到訪問是/否領域的話，我會嘗試刪除單引號（'）從第二INSERT INTO行：

string query1 = "INSERT INTO [Team Member] 
(Soccer, Basketball, Football,  Softball) 
VALUES(" + c1.Checked.ToString() + ", " 
+ c2.Checked.ToString() + ", " 
+ c3.Checked.ToString() + ", " 
+ c4.Checked.ToString() + ")"; 

Answer 2

首先，您的複選框值永遠不會被插入的原因是因爲您的OleDbCommand是這樣定義的：

OleDbCommand cmd = new OleDbCommand(query, conn); 

使用query作爲command.text。 query1永遠不會被引用，因此永遠不會執行。

其次，更重要的是，您需要將insert語句作爲一個語句，而不是2.調用2個Insert語句會導致將2個行添加到表中。一個包含來自查詢的值，另一個包含來自query1的複選框值。你應該在這樣一個字符串中定義你的查詢

string query = "INSERT INTO [Team Member] " + 
     "(FirstName, LastName, Email, Pass, Age, Hobbies, FavoriteColor, Major, Soccer, Basketball, Football, Softball) " + 
     "VALUES('" + txtFirst.Text + "','" + txtLast.Text + "', '" + txtEmail.Text + "','" + txtPass.Text + "','" + 
     txtAge.Text + "','" + txtHobbies.Text + "', '" + txtFavorite.Text + "','" + txtMajor.Text + "','" + 
     c1.Checked.ToString() + "', '" + c2.Checked.ToString() + "', '" + c3.Checked.ToString() + "', '" + c4.Checked.ToString() + "')";
