Whats the best method and or tools to move a MsSQL database to MySQL ?
Please be as literal as possible as I have limited experience with databases and next to none with moving them.
MySQL itself offers a Migration Toolkit, which - in my experience - works rather well, not only with SQL-Server, and is as easy as it can get.

I found alot of question on stack about converting mysql to mssql, but i would like to convert it otherwise.
From mssql server to mysql.
is there a (free) tool for this to do that without connecting to the databases?
i have an sql query dump and i want to convert that by putting that code in an tool.
Thanks.
You're probably best off doing this yourself to ensure everything is correct rather than relying on a third party tool (Also the additional benefit of understanding the differences between the two pieces of code). However you could use this SQL to MySQL tool:

I am planning to use Locomotive for a project...But as the official website says it cannot work with MySQL. However my requirement is to use it with MySQL.
Has any one used it with mySQL? Any pointers or advises would be great. Thanks.
Cheers,

Locomotive uses Mongoid - which is an ORM for MongoDB. As such, you cannot use it with MySQL at all, since it leverages some features (dynamic attributes), which traditional RDBMS databases (such as MySQL) do not support.
That being said, MongoDB is pretty easy to install, so if you can get around your requirement of MySQL, then you should have no problems.
Decoupling Locomotive from MongoDB would be no small task at the moment, which is not to say that it is impossible.
Regarding your requirement of MySQL, if you are working on incorporating Locomotive into a larger web-application, one thing to consider is that your non-Locomotive models can still live in MySQL regardless of where Locomotive keeps its data.
From what i know it wont be possible to use locomotive only with mysql as it use heavily mondodb.
However it's not a problem to build your app living together with locomotive and use what ever orm you like.
Just configure your database.yml and the magic will happend ;)

This not a go/no go question. I've used all kinds of 4GLs (PL/SQL, T-SQL, PGSQL etc.) for database back-end coding and find very useful to establish data layer "closest" to database engine.
Now MySQL stored procedures got my attention and very interested in coding in this brand new 4GL platform.
I would like to start using it in one of my proof of concept projects. What you folks think about MySQL stored procedures? Crucial question is; Is it reliable? How "Oracle Corporation" supports MySQL stored procedures (i.e. documentation, forums etc.)?
Thanks
Support started in v5.0, it's currently in v5.1 (v5.5 is in the pipe). If they weren't reliable, they'd have been removed.
I don't know what you mean by "how Oracle supports it" - the syntax is different, rarely (if ever) will you be able to port an Oracle stored procedure directly to MySQL without alteration.
A mySQL stored procedure will be as reliable as you make it. If you write it to do everything you need then it will be fine. If you don't it wont.
As #OMG states they began supporting in version 5.0.
What do you mean when you ask how Oracle supports it?
What tools are you using to track changes in your MySQL database? Currently I'm in a project where we use a plain text-file (version controlled via SVN) in which we manually add SQL statements when making changes to the database.Many of the changes magically disappears every now and then, and we are now looking for a better way to change track our database.
EDIT:
One thing that I forgot to mention, we are using stored procedures and functions, so it's not only the database structure that we want to track changes on / version controll.
There is a simple solution:
Make all changes to the database schema and static data via scripts
Version control the scripts
Toad for MySQL has a great schema comparison tool

I think you need something like this (I test it for Firebird and it works very well) :

I thought there was a MySQL version but NO :(
for MySQL, I see just this :

But if it is just for development, I think that the answer given here is good
mysql-diff compares tables, but not stored procedures yet.
I'm looking for a tool that can map the relationships in my database in mysql. I would like something like the view that is generated in MS-SQL Server Management Studio in the 'Show Diagram Pane'. Does such a thing exist?
I'm in charge of the design of the database and its using rails conventions. I would not be adverse to specifying relationships by hand.
Doesn't MySQL Toad have a schema diagram tool? I think it does. I'm not a diagram guy (much happier with mysqldump output) but I've worked with many people who swear by Toad.
Maybe the official tool has that?

MySQL Workbench 5.1.16 is buggy on my OS X 10.5.7 system. I found that it does things like crashes and vanishes with no error. Or it will error out when trying to change page size in the print setup.
I also tried running it on Windows XP under VMWare. It seemed more stable and usable there. I was able to reverse engineer a DB and create a diagram.
One year ago I used DBVis together with Oracle. It believe it also works with MySql.
Altova DatabaseSpy will show them if you are on Windows. If not, the easiest way is to query INFORMATION_SCHEMA (if you're using v5 or later of MySQL) and check out the key column usage statistics for all the tables. This is easy to script.
Most MySQL databases still use MyISAM tables, which do not provide foreign key constraints. Without explicit FKs the best you can do is guess at the relationships between tables.
