Bug reference: 1027
Logged by: William H Copson
Email address: copson@u.arizona.edu
PostgreSQL version: 7.5 Dev
Operating system: Redhat 7.2 (highly modified)
Description: incorrect result from 'order by'
Details:
The following:
drop table tst;
create table tst (
name varchar(25));
insert into tst values ('LEE,ADAM');
insert into tst values ('LEEBERMAN,JOHN');
insert into tst values ('LEE,RALPH');
select name from tst order by name;
Produces the following output:
DROP TABLE
CREATE TABLE
INSERT 3307587 1
INSERT 3307588 1
INSERT 3307589 1
name
----------------
LEE,ADAM
LEEBERMAN,JOHN
LEE,RALPH
(3 rows)
Expected output:
name
----------------
LEE,ADAM
LEE,RALPH
LEEBERMAN,JOHN
(3 rows)
I have tried databases with SQL_ASCII, LATIN1 and LATIN2
encoding with the same result.
From this small example and others involving an employee
table (80K+ records) it appears that the comma is being
parsed out prior to the sort (i.e. 'LEEB' sorts after
'LEEA' and before 'LEER').
