why don't string function work in WHERE clause?
Here's a sample:
select column1 from table1 where lower(column1) = 'some_string'
will not give me any results although column1 (defined as char[50]) has
values like
'Some_string' or 'SOME_STRING'
if for instance I say something like:
select lower(column1) from table1 where column1 = 'SOME_STRING'
then it returns 'some_string' correctly. The same thing happens with
'upper' and similar functions. Why don't they work when they are in
WHERE clause?

try
select column1 from table1 where trim( lower(column1) ) = 'some_string'
As someone in the archives has said, char is evil. And varchar is your friend.
