Here's the problem....

 

I have a table with a column called "last_name".  I have one customer who likes to articulate queries and updates for this using column name "last_name" (no problem there) but another who likes to call it "lname" and yet another who likes to call it "surname".    So 3 different names for the same physical column in the table.

 

I know a view can be used to alias one of them. But what about the other 2?  Three views (or 2 views and the main table) is awkward.  Also, you can't modify the data through a view.

 

I thought of having a table with the 3 column names in there "last_name", "lname" and "surname".  The queries should work fine.  As for the updates and inserts,  have a before trigger make sure they're all synched up.  But that only works if only one of the value changes, otherwise how do you know which one to sync up to! Hmmmm.....

 

Does anyone know of an elegant way to do this? 

 

Thanks in Advance
