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
