Re: RFC: mysql-native - Supporting both Vibe.d and Phobos sockets

[Gary Willoughby]

Hi, i've tried using this library for a simple query and i run 
into an error. I wondered if this is a bug in the connection code.

MySql schema:
CREATE TABLE tblUser (
  id int(11) NOT NULL AUTO_INCREMENT,
  name varchar(255) NOT NULL,
  age varchar(45) NOT NULL,
  date timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE 
CURRENT_TIMESTAMP,
  PRIMARY KEY (id),
  UNIQUE KEY (name)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

D code:

import mysql.connection;
import std.stdio;

void main(string[] arguments)
{
	auto connection = new Connection(MySQLSocketType.phobos, 
"127.0.0.1", "root", "r00t", "Project");
	auto command    = new Command(connection, "SELECT * FROM 
tblUser");
        auto results    = command.execSQLResult();

        foreach (row; results)
        {
                writeln(row);
        }

        connection.close();
}

Error:

If i comment out the assert on line 1046 in connection.d 
everything seems to work fine. Any thoughts?
