If you are creating tables, views, etc on the fly (other than table variables or temp tables), you may truly need to rethink your design. This is not stuff that should normally happen from the user interface. Even if you must allow some customization, the DDL statements should not be happening at the same time as running transactional inserts/updates/deletes. It is far better to separate these functions.

This is also something that needs a healthy dose of consideration and testing as to what happens when two users try to change the structure of the same table at the same time and then run a transaction to insert data. There's some truly scary stuff that can happen when you allow users to make adjustments to your database structure.

Also some DDL statements must always be the first statement of a batch. Look out for that too when you are running them.
