Обсуждение: Upper and Lower case sensitivities

Hey,

Is there a function within postgres that lets you search for both upper and
lower case at the same time?
I know of the upper() and lower() functions but if a word has both upper and
lower case in it it won't be returned by a query.
Or am I limited to forcing my data to have one case only?

Thanks
Scott

select * from foo while column_name ~* 'matchstring';

Try using ~*
