How can I make SQL Server return FALSE for comparing varchars with and without trailing spaces?

Question

If I deliberately store trailing spaces in a VARCHAR column, how can I force SQL Server to see the data as mismatch?

SELECT \'foo\' WHERE \'bar\         


        

Answer 1

After some search the simplest solution i found was in Anthony Bloesch WebLog.

Just add some text (a char is enough) to the end of the data (append)

SELECT 'foo' WHERE 'bar' + 'BOGUS_TXT' = 'bar    ' + 'BOGUS_TXT'

Also works for 'WHERE IN'

SELECT 
FROM 
WHERE  + 'BOGUS_TXT' in ( SELECT  + 'BOGUS_TXT' FROM  )
