I'm sure there is a dirty way of doing it. Maybe a trigger on the MS SQL table that writes out, to a text file?, the type of action, ie. Add/Del/Update that occured on the table along w/ the data elements that were added/updated. Then the MySQL could pick that file up and process the change to its table.
I do not believe there is a connection type for processing transaction from a SQL Server DB to a MySQL DB. But I may be mistaken.
