RE: SQL Alter table: can I remove the UNIQUE attribute from a key?

["Stone, Joel" <Joel.Stone@xxxxxxxxxx>]

OK but this thread doesn't state how to compare all columns while ignoring the key and NOT naming each individual column.

Is this possible?

   FWiW the "SQL" is unlikely to have been mentioned by most people even 
though they are offering an SQL statement.  If the likely statement is 
"SELECT", then use that token instead of "SQL".  Anyhow, one possible 
search:

http://www.google.com/search?q=comparing+union+except+2013+site%3Aarchive.midrange.com%2Fmidrange-l

   The above search yielded two threads [plus this one; for obvious 
reasons] from 2013.  One had the "2 days ago" conspicuously noted in the 
results:
