Re: how do you handle your DDL builds?

Use TOAD or any other tool that can create DDL from database objects and compare schema in two database.

1. Use a small database with structure only, After making changes rebuild the whole table there and use TOAD to compare the structures.
2. After applying your changes you simply use TOAD to generate scripts from the newly changed objects.

In my opinion you needs this only if you do fresh installs of your objects, like a product that you sell.
For internal use, you can alway do export, structure only, and load this into a new database.
