CheckBox不发送检查值以访问数据库C＃Asp

Question

这是我的C＃代码，我的问题是标题是我的复选框值没有进入我的访问数据库，或者至少没有更改它们。

我的数据库看起来像这样

Answer 1

如果您要附加Access Yes / No字段，那么我会尝试从第二个INSERT INTO行删除单引号（＆＃39;）：

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，您的复选框值永远不会被插入的原因是因为您的OleDbCommand定义如下：

OleDbCommand cmd = new OleDbCommand(query, conn);

使用query作为command.text。 query1永远不会被引用，因此永远不会执行。

第二个（更重要的），您需要将insert语句作为一个语句而不是2.调用2个Insert语句将导致将2行添加到表中。一个包含查询中的值，另一个包含来自query1的复选框值。您应该在一个字符串中定义您的查询，如

    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() + "')";
