When creating alter table SQL, the MySqlPlatform class does not quote names for columns of an existing table when building a CHANGE query. This can cause SQL errors.
It creates queries like this:
ALTER TABLE my_table CHANGE key `key` INTVARCHAR(255) DEFAULT '' NOT NULL';
Attached is a patch to fix this.
As an aside, is this the best way to contribute a patch? Or is a GitHub pull request better?
