the role db_owners, being a built in role, cannot be modified.
instead, create your own role , ie '[AlmostOwners]', and assign the privileges you want.
then remove db_owner from the users, and add your new role instead.
something like this:
CREATE ROLE [AlmostOwners]
EXEC sp_addrolemember N'db_ddladmin', N'AlmostOwners'
EXEC sp_addrolemember N'db_datareader', N'AlmostOwners'
EXEC sp_addrolemember N'db_datawriter', N'AlmostOwners'
--can the users EXECUTE procedures? comment out if false
GRANT EXECUTE TO [AlmostOwners]
--allow the users to see view proc and function definitions
Grant View Definition ON SCHEMA::[dbo] To [AlmostOwners]
--finally add our user to the role:
EXEC sp_droprolemember N'db_owner', N'ClarkKent'
EXEC sp_addrolemember N'AlmostOwners', N'ClarkKent'
