First might I just say that I've been waiting *years* for red gate to make mysql versions of red gate sql compare and sql data compare. I've used Sql compare / Sql data compare for years on Sql server and these are amazing tools! Great to see Sql compare for mysql.

Anyway, I am comparing the structure of 2 mysql databases. During the synchronisation, I got an error message from sql compare and the sync did not complete. Unfortunately, I notice that the synchronisation has been partly completed so the structure changes were not wrapped in a transaction. This is not good!

The database in question has a mix of innodb and myisam tables - perhaps this has something to do with it?

Thanks for the kind message. I've forwarded to our development team but believe the problem may actually be whether schema changes can even be wrapped in a transaction in MySQL. Please correct me if I'm wrong, but I've included a couple of similar questions posted online who's answers suggest this:
