If your table is called "LOCATION" it will only be matched by "LOCATION";
the original use of double quotes makes their use mandatory for ever
after. SQL is case-insensitive when double quotes are not used;
your second example (select * from LOCATION) gets translated to lower-case
immediately, which is why you don't get a match on it. This is correct
behaviour.

Best to avoid case-sensitive names altogether.
