It's hard to believe you expect the random order of SQL statements returned from a hash to remain acceptable for long. But rather than pick at details, I believe the greatest improvement would be to think about code design at the highest level. Consider organising your functionality into separate utility modules. I use a master-class module for methods I want to call from anywhere and a DB module for utilities that relate to databases and files. In this case you probably want a subclass called e.g. DB::Queue for managing a statement queue object and methods for appending, executing and transaction behavior (e.g. commit or rollback the lot) for these queues. It is rarely a good idea to build complex code that only services local blocks. Often you will be rewarded when generic code proves actually much easier to write and test.

Snippets of code should be wrapped in

tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
