wrong order when using collation DE_DE
--------------------------------------
Key: CORE-4026
URL: http://tracker.firebirdsql.org/browse/CORE-4026
Project: Firebird Core
Issue Type: Bug
Components: Charsets/Collation
Affects Versions: 2.5.2
Environment: Win7, XP, Firebird 2.5.2
Reporter: Volker Rehn
Only digits and alphabet characters are used for sorting, everything else
(#$%&_[]{}/"!<>~+*:;,. etc) is ignored. Collation DE_DE is not a CI_AI etc
collation, it should work with other characters too. Test case:
CREATE TABLE TBL (
ENTRY VARCHAR(30) COLLATE DE_DE
);
INSERT INTO TBL (ENTRY) VALUES('0');
INSERT INTO TBL (ENTRY) VALUES('''+''0 %;''-''0 %');
INSERT INTO TBL (ENTRY) VALUES('0.00');
INSERT INTO TBL (ENTRY) VALUES('0.00 %');
INSERT INTO TBL (ENTRY) VALUES('''+''0.000;''-''0.000');
INSERT INTO TBL (ENTRY) VALUES('abc');
INSERT INTO TBL (ENTRY) VALUES('def');
INSERT INTO TBL (ENTRY) VALUES('NNN');
INSERT INTO TBL (ENTRY) VALUES('yyy');
select entry from tbl
order by 1
gives:
ENTRY
=============
0
'+'0 %;'-'0 %
0.00
0.00 %
'+'0.000;'-'0.000
abc
def
NNN
yyy
