我有一个这样的excel文件：
我有两个 TextBox(Fname,Lname) 、两个 Button(Search,Insert) 和一个 GridView 来显示结果。搜索按钮工作正常，但插入按钮不起作用。
插入按钮的错误是：
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>
后面的代码：
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();
}
