Hi!

How do i convert a result to upper/lowercase?

I'ld like to do the following:

SELECT UPPER(lang) from languages;

and get for example "uk" as "UK", "dk" AS "DK" and so on…

Sincerely

Victor

This is a question

and this is the answer. It works exactly like this:

SELECT UPPER('dk');

results in 'DK'

kind regards,
Janning

That looks right to me. Are you getting an error?

lee=# select version();
                               version
---------------------------------------------------------------------
PostgreSQL 7.4.2 on i386-portbld-freebsd4.9, compiled by GCC 2.95.4
(1 row)

lee=# select UPPER('MixED CaSes');
    upper
-------------
MIXED CASES
(1 row)

lee=# select lower('MixED CaSes');
    lower
-------------
mixed cases
(1 row)

That's what you do. For example:
bruno=> select upper('test');
 upper
-------
 TEST
(1 row)

You can do exactly that, upper() and lower() functions exist:

Aren't we now back to the recent thread about UTF-8 and case conversion?
How do you make UPPER and LOWER work on a multi-byte encoded stuff?
How do you get a properly alphabetized return set that, for example,
contains English, German, French, Spanish, Russian and Turkish records?
