On Sybase DBs, the timestamp column cannot be updated with a query,  
the server does it automatically([http://www.sybase.com/detail](http://www.sybase.com/detail)?  
id=20316). Since ActiveRecord writes all attributes back to the  
database on every call to #save, the transaction error. To get by I  
edited the default sybase\_adapter to not include timestamp types when  
it returns the column listing, thus eliminating that attribute all  
together. But now if I want to read that attribute, I’m out of luck.

Has anyone else run across this issue? Is there some way I can fix the  
problem without modifying the sybase\_adapter?
