Hey there :)

I'm using Ruby on Rails to create a migration of a legacy database on
an MS SQL Server. I'd like to name my constraints myself, such as
'pk_authors', but in the cases where a table has an auto incremented
IDENTITY(1,1) id field, Rails takes over and adds the primary key
itself when creating the table.

This is fine, except then the constraint gets a name like
'PK__authors_384934' which is not very intuitive or easily remembered
;)
I'd like to just throw in an 'ALTER TABLE authors...' statement just
after that table has been created, but I'm not sure how to go about
renaming the auto generated constraint since the name it gets is
partially random. Is there any way to indirectly refer to the
constraint like 'RENAME PRIMARY KEY CONSTRAINT ON authors TO
pk_authors' or something like that, so that I can rename the
constraint?

Thanks in advance,
Daniel Buus :)
