transactionsSupported is disabled for my sql


I look at the code in the and see this:

    else if (dbName.indexOf("mysql") != -1) {
        databaseType = DatabaseType.mysql;
        transactionsSupported = false;

and I wonder why the member “transactionsSupported” disabled in case of mysql database? is there any problem with mysql transactions?

getTransactionConnection() method has no affect if the memeber “transactionsSupported”=false.

thanks in advance if anyone knows the answer for that…
