Обсуждение: How to Make Case InSensitive???

When I use SQL statements, how can I make it case insensitive. If I
use

    SELECT * FROM series WHERE NAME='India'

I want to select rows including those where NAME='INDIA' / NAME =
'india'
and so on.

Can someone help me in the above??

Regards

     SELECT * FROM series WHERE upper(NAME) = 'INDIA'
                            or
     SELECT * FROM series WHERE NAME ~* '^india$'

Hey...

How does this " ~* " operator works ?!?!?!

I don't use it myself, but it is a case insensitive regular expression
match operator.    "~' is the case sensitive operator.    Do "\do" in
psql to see all the operators.
