Question

I want to check if my query in methode ExecuteNonQuery() is running.
here is my code in my WCF Service:

 public string Execute(string query){
            string connectionString = ConfigurationManager.ConnectionStrings["ConnWf"].ConnectionString;
            string hasil = "ERROR";
            using (SqlConnection conn = new SqlConnection(connectionString))
            {
                conn.Open();
                string cmdStr = String.Format(query);
                SqlCommand command = new SqlCommand(cmdStr, conn);
                command.Connection.Open();
                command.ExecuteNonQuery();

                //I want to check here..
                if (command.ExecuteNonQuery().HasRows) //it doesn't works :(
                {
                    hasil = "SUCCESS \n Row Affected: " + rd.RecordsAffected;

                }
                else
                {
                    hasil = "FAILED \n Row Affected: " + rd.RecordsAffected;
                }
                conn.Close();
            }
            return "Query: "+query+"\n Status: "+hasil;
        }

Answer 1

ExecuteNonQuery() returns an integer which will be the sum of rows affected by your sql statement. i.e. if SSMS returned:

(614 row(s) affected)

(123 row(s) affected)

ExecuteNonQuery() would return 737.

So you could use something like this.

try
{
    hasil = string.Format("Success \n Rows Affected: {0}", command.ExecuteNonQuery());
}

catch
{
    hasil = "Failed \n Rows Affected: 0";
}

You should also consider a using block for your SqlCommand as well as your SqlConnection.
