Yep. Theres no reason at all why this sort of thing won't work for MSSQL too. Use SQL Enterprise Manager to generate a create script for all objects in the database, and also tell it to script referential integrity (FKs, etc).
Then add anything MySQL specific, such as Type=InnoDB (which you will need for transactions/FKs, although I believe BDB works as well?).
The only possible problem you will run into is with any code that is embedded into the database - stored procedures shouldn't be too bad, as the syntax in MySQL is fairly similar, you'll just end up changing some function names and tweaking (unless you have very complicated MS SPs). Remember that there are no table variables in MySQL, and that the syntax to create a temporary table is 'create temporary table xyz' not 'create #xyz'.
Views of course, are a different matter. In terms of the database structure itself, without embedded code though, it should work perfectly...
Cheers,
Matt

Hi Rodrigo.
I'm facing a similar task but from Informix to MySQL. What I do is:
1. Obtain a SQL script to create the logical database (an Informix tool give it). You can use Erwin, with reverse engineer and the save the script.
2. Add the "Type=INNODB" clause for each CREATE sentence.
3. Divide the scritp into tow: one for the tables creation (with its primary key) (CreateDB.sql) and another one for the alter tables to create the foreing keys (AlterDB.sql).
4. Create a script for loading data from TXT files. First you have to save every table data from SQL Server into TXT files, then load them into MySQL tables (LoadDB.sql).
5. Run the AlterDB.sql script (step 3).
It works fine to me.
Regards, David.

Subject: MSSQL to MYSQL
Hello list,
I have to move a database in MSSQL to MYSQL, with the table structures and all the respective data. I tested one product to do this,
SQLyog, and it works fine, except for some little problems with indexes and primary/secondary keys. I want to know if anyone have been dealing with the same problem to recommend me some suggestions/tips/tricks. Do you know another program/script/ways to do this migration ? I want to migrate everything from the original MSSQL database, like indexes, relationships, and so on. Can you guys recommend me some actions or tips
to take ? Thanks in advance,
