C# MYSQLWrapper Class and PHPWrapper-Script

Introduction

The MYSQLWrapper class is a small and simple-to-use solution for accessing server side MySQL databases at a standard webspace that supports PHP and MYSQL.
I thought it would be useful because many of you have got those cheap PHP/MYSQL supported sites and want to use data at the client side.
SQL queries and non query commands proceed as follows:

1. The client side C# program passes the needed SQL command to the server side script using HTTP request.
2. The server side script performs SQL statement and returns the result, if there is any, back to the client.
3. Now the client parses the returned data and creates a Resultset that behaves similar to the sqlDataReader.

Using the Code

In order to implement this, you have to check two main parts:

1. The PHP Script
   • FTP the PHP Script up to your site
   • Make changes to the script regarding specific MYSQL Server information, shown in this line of wrapper.php:

   $W->assign("mysql.mydomain.com","sqluser","sqlpwd",$database,$statement);
   

2. The client class
   • Add the CL_MYSQLWrapper class to your project and make sure that you use namespace MYSQLWrapper like this:
   C#

   using MySQLWrapper;
   

   Now you can use wrapper class easily to perform DDL, DQL and DML statements like this:

   C#

   // Instantiate Wrapper Class with your script URL
   MySQLWrapper W = new MySQLWrapper("http://www.mydomain.com/wrapper.php");
   
   // Query server side db and get your resultset
   MSWRecordSet R = W.Query("MYDB", "SELECT * FROM t_persons");
   
   // Print out results, in this case the field f_name
   while (R.Read())
   {
       Console.WriteLine(R.Fields["F_Name"].ToString );
   }
   
   // Make a non query and update something.
   W.NonQuery("MYDB", "UPDATE t_persons SET F_Name='nobody'");
