如何通过ASP.NET中的ODBC连接将查询插入Excel？

Question

I have an excel file like this:

I have tow TextBox(Fname,Lname) , tow Button(Search,Insert) and one GridView to show result. Search button work fine but Insert button not work.

Error in insert Button is:

ERROR [HY000] [Microsoft][ODBC Excel Driver] Operation must use an updateable query.

ASPX:

Fname:<asp:TextBox ID="txtFname" runat="server"></asp:TextBox><br />
Lname:<asp:TextBox ID="txtLname" runat="server"></asp:TextBox><br />
<asp:Button ID="cmdSearch" runat="server" onclick="cmdSearch_Click" Text="Search" />
<asp:Button ID="cmdInsert" runat="server" onclick="cmdInsert_Click" Text="Insert" /><br />
<asp:GridView ID="GridView1" runat="server"></asp:GridView>

Code behind:

string conStr = @"Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};"+
    @"DBQ=|DataDirectory|\q.xlsx;";
protected void cmdInsert_Click(object sender, EventArgs e)
{
    OdbcConnection con = new OdbcConnection(conStr);
    con.Open();
    string query = "insert into [Sheet1$] (Fname,Lname) values (?,?)";
    OdbcCommand cmd = new OdbcCommand(query, con);
    cmd.Parameters.AddWithValue("?",txtFname.Text);
    cmd.Parameters.AddWithValue("?", txtLname .Text);
    cmd.ExecuteNonQuery();// has error
    con.Close();
}
protected void cmdSearch_Click(object sender, EventArgs e)
{
    OdbcConnection con = new OdbcConnection(conStr);
    con.Open();
    string query = "";
    query = "select * from [Sheet1$] where Fname=? or Lname=?";
    OdbcCommand cmd = new OdbcCommand(query, con);
    cmd.Parameters.AddWithValue("?", txtFname.Text);
    cmd.Parameters.AddWithValue("?", txtLname.Text);
    GridView1.DataSource = cmd.ExecuteReader();
    GridView1.DataBind();
    con.Close();
}

Answer 1

Per http://support.microsoft.com/kb/316475

make sure you add "ReadOnly=0"

string conStr = @"Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};"+
@"DBQ=|DataDirectory|\q.xlsx;ReadOnly=0;";

使用更结构化的东西，例如LinqToExcel （您也可以在NuGet中找到它），它确实易于使用，并且在幕后使用ODBC可以解决错误或至少缩小可能的错误的范围。
