Hi,
Why do I get the following result from the query below? I expected that,
given the fact that there are over 100 "Jansen" (but no "jansen") in
"Nijmegen" the first record would definitively be people living in
"Nijmegen". If I change the order to the order that is commented out,
the query goes OK.
SELECT
addresses.zipcode,
addresses.city,
addresses.housenumber,
addresses.housenumberdetails,
customers.lastname
FROM prototype.customers JOIN prototype.addresses ON
customers.contactaddress = addresses.objectid
WHERE
TRIM(UPPER(customers.lastname)) >= TRIM(UPPER('Jansen'))
AND
TRIM(UPPER(addresses.city)) >= TRIM(UPPER('NIJMEGEN'))
ORDER BY customers.lastname, addresses.city, addresses.zipcode
--ORDER BY addresses.city, customers.lastname, addresses.zipcode
limit 5
Result:
"3089TN";"ROTTERDAM";"5";"";"jansen"
"5712XG";"SOMEREN";"13";"";"jansen"
"6511PS";"NIJMEGEN";"23";"";"Jansen"
"6523RE";"NIJMEGEN";"13";"";"Jansen"
"6524NP";"NIJMEGEN";"37";"A";"Jansen"
TIA

Because that is what I want: I want everyone that is called "xxxx" and
lives in a city that is equal or larger than "yyyy". Jansen and Nijmegen
are just examples.

What do you mean by that?

What LOCALE are you using?
Looks like it either sorts lowercase before uppercase
or treats them as equivalent.
Why do you not provide us with a simple test case?
Why involve a join and irrelevant columns?
What does a simple test like this do for you?:
test=# create table t (c text, n text);
CREATE TABLE
test=# insert into t values ('ROTTERDAM','jansen');
INSERT 33566780 1
test=# insert into t values ('SOMEREN','jansen');
INSERT 33566781 1
test=# insert into t values ('NIJMEGEN','Jansen');
INSERT 33566782 1
test=# insert into t values ('NIJMEGEN','Jansen');
INSERT 33566783 1
test=# insert into t values ('NIJMEGEN','Jansen');
INSERT 33566784 1
test=# select * from t ORDER BY n,c;
c | n
-----------+--------
NIJMEGEN | Jansen
NIJMEGEN | Jansen
NIJMEGEN | Jansen
ROTTERDAM | jansen
SOMEREN | jansen
(5 rows)
(this in in C locale)
