mssql2mysql

Simple MSSQL Server to MySQL table converter using PHP CLI.

Prerequisites

Make sure you have PHP mssql extension and PHP mysql extension extensions installed.

On Debian/Ubuntu Based

sudo apt-get install php5-mssql php5-mysql

On Centos/Redhat Based

sudo yum install php5-mssql php5-mysql

On MacOSX using Brew

brew install php5-mssql php5-mysql

Usage

Edit the MSSQL and MySQL hostname, user, password, and database section. Run the script from command line using PHP CLI.

Example:

1. Edit the file mssql2mysql.php using your favourite editor.

2. Change MSSQL and MYSQL variables:

   /*
    * SOURCE: MS SQL
    */
   define('MSSQL_HOST','mssql_host');
   define('MSSQL_USER','mssql_user');
   define('MSSQL_PASSWORD','mssql_password');
   define('MSSQL_DATABASE','mssql_database');
   
   /*
    * DESTINATION: MySQL
    */
   define('MYSQL_HOST', 'mysql_host');
   define('MYSQL_USER', 'mysql_user');
   define('MYSQL_PASSWORD','mysql_password');
   define('MYSQL_DATABASE','mysql_database');
   

3. Run the php script (make sure php is accessible in the path or environment variables)

php mssql2mysql.php

Common errors and fixes

Sometimes you will get an error like:

PHP Warning:  mssql_query(): message:
Unicode data in a Unicode-only collation or ntext data cannot be sent to clients using DB-Library
(such as ISQL) or ODBC version 3.7 or earlier. (severity 16) in ... on line 181

The easiest fix for users on unix systems would be to configure freetds. Make sure the version is 7.0 not 4.2:

sudo vim /etc/freetds/freetds.conf

[global]
# TDS protocol version
tds version = 7.0
