ORA-00936: missing expression while executing in C#.

Question

I am writing a function for inserting BLOB file in to ORACLE. While executing the code I am getting the error stating that ORA-00936: missing expression .

My Code:

public static void DatabaseFilePut(MemoryStream fileToPut, OracleConnection con)
    {
     try
      {
       byte[] file = fileToPut.ToArray();
       const string preparedCommand = @"INSERT INTO user_account_statement (statement_id,session_key,login_id,user_id,account_number,
       from_date,todate,ipaddress,
       create_date_time,STATEMENT_FILE) VALUES(1073,'fe79e0345986b5a439c26f731234868b53f877366f529',
       2335,'204254','108142',to_date('2014-08-23 16:45:06','yyyy-mm-dd hh24:mi:ss'),
       to_date('2014-08-23 16:45:06','yyyy-mm-dd hh24:mi:ss'),
       '106.79.126.249',to_date('2014-08-23 16:45:06','yyyy-mm-dd hh24:mi:ss'),file)";
       using (var sqlWrite = new OracleCommand(preparedCommand, con))
       {
        sqlWrite.ExecuteReader();
       }
      }
      catch (Exception ex)
       {
         MessageBox.Show(ex.ToString());
       }
    }

Please advise where I am going wrong.

Answer 1

I specified parameter for 'file'

sqlWrite.BindByName = true;
                var blobparameter = new OracleParameter
                {
                    OracleDbType = OracleDbType.Blob,
                    ParameterName = "ssfile",
                    Value = fileToPut.ToArray()
                };
                sqlWrite.Parameters.Add(blobparameter);

and changed parameter name too. because the parameter name file is ORACLE's reserved word. So it might create another problems.
