Subject: [GENERAL] How to implement a value alias or synonym

 

Hi:

 

v9.0.1 on linux

 

Is there a way to query on synonyms of a value transparent to the user?

For example, a column called "animal" can have any text value, including
'horse' and 'cow' and 'pig'.  But I want the user to find all the
animal='pig' records if they specify 'hog' instead.  

So.. 

               select * from thetable where animal = 'pig'

..would generate the same results as...

               select * from thetable where animal = 'hog'

 

There are no 'hog' records in the table, just 'pig' records.  And I want
to have control over the synonyms, perhaps in some sort of ref table ?

 

Thanks in Advance for any ideas.
