ExecuteNonQuery doesn't respond?

Question

I want to update some columns on my table but ExecuteNonQuery doesn't respond (Timeout). Did I do something wrong?

Notes: in the database table, id is integer, F1 varchar2 and the parameters I am sending are string and int.

try {
    using (OracleConnection con = new OracleConnection(ConString)) {
                con.Open();

                OracleCommand cmd = new OracleCommand();
                cmd.Connection = con;

                cmd.CommandText = "UPDATE DB.Table "+
                                  "SET F1= :yd" +
                                  "WHERE ID = :id";

                cmd.CommandType = CommandType.Text;

                cmd.Parameters.Add("yd", yd);
                cmd.Parameters.Add("id", id);


                cmd.ExecuteNonQuery();

                con.Close();
                return true;
    }
}
catch (Exception ex) {
    return false;
}

Thanks

可以通过在Oracle开发人员或计算机上运行的任何其他IDE上 提交或回滚未决事务来解决此问题。

You're mixing up your parameter names. There is no parameter named "F1" in your query, use "yd".

            cmd.CommandText = "UPDATE DB.Table "+
                              "SET F1= :yd" +
                              "WHERE ID = :id";

            cmd.CommandType = CommandType.Text;

            cmd.Parameters.Add("yd", yd);
            cmd.Parameters.Add("id", id);

I found that is because of other program like toad locks the query. After commiting all thing in toad, everything is solved.

Thanks for all for helping. I love you guys, i like brainstorming :)

            cmd.Connection = con;

       string qry = "UPDATE DB.Table "+"SET F1= @yd" +"WHERE ID = @id";

        OracleCommand cmd = new OracleCommand(qry,con);
            cmd.Parameters.AddWithValue("@yd", yd);
            cmd.Parameters.AddWithValue("@id", id);

            cmd.ExecuteNonQuery();
