> We use the WriteSchemaToFile task to store our applications schema in a file we place in our Subversion CM tool. Every time we run this task, it reorders the foreign keys on a table. So, for example, if Table A has FKs X, Y, Z then schema.xml file alternates between:
> <table ...>
> <fk name='X' .../>
> <fk name='Y' .../>
> <fk name='Z' .../>
> </table>
> AND
> <table ...>
> <fk name='Z' .../>
> <fk name='Y' .../>
> <fk name='X' .../>
> </table>
> Notice, that the keys haven't changed between schema dumps, just the ordering of them in the file. This means tracking version changes is more complicated as a developer's real changes are mixed in with these spurious key position changes.
