Is it possible to convert all text within a sheet to all lowercase or all uppercase?

I would like to use this formula to extract data from a master sheet:

=query('total data'!A3:D,"Select * Where B contains """&B2&""" ")

It works really well, but I am finding the "contains" option will only return matching case text from the B column. I figure if I can format all the text in the 'total data' B column to be either upper or lower case, then the problem is solved!

I'd be most grateful for any solutions or other suggestions.
