Subject [jira] Updated: (DERBY-3279) Derby 10.3.X sorts VARCHAR column incorrectly when table is indexed and VARCHAR column contains a value of '00000'
Date Fri, 14 Dec 2007 21:26:43 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3279?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ajay Bhala updated DERBY-3279:
------------------------------

    Description: 
Running the following produces the error seen in Derby 10.3.X but not in 10.2.X nor in 10.1.X.
Don't know if this related to DERBY-3231.

First query is incorrectly sorted whereas the second one is okay when there is an index on
the table. 
If the table is not indexed, the sort works correctly in DESC order.
------
create table CHEESE (
  CHEESE_CODE       VARCHAR(5),
  CHEESE_NAME       VARCHAR(20),
  CHEESE_COST       DECIMAL(7,4)
);

create index cheese_index on CHEESE (CHEESE_CODE DESC, CHEESE_NAME DESC, CHEESE_COST DESC);

INSERT INTO CHEESE (
  CHEESE_CODE,
  CHEESE_NAME,
  CHEESE_COST)
VALUES ('00000', 'GOUDA', 001.1234),
       ('00000', 'EDAM', 002.1111),
       ('54321', 'EDAM', 008.5646),
       ('12345', 'GORGONZOLA', 888.2309),
       ('AAAAA', 'EDAM', 999.8888),
       ('54321', 'MUENSTER', 077.9545);

SELECT * FROM CHEESE 
WHERE (CHEESE_CODE='00000' OR CHEESE_CODE='54321') AND CHEESE_NAME='EDAM'
ORDER BY CHEESE_CODE DESC, CHEESE_NAME DESC, CHEESE_COST DESC;

SELECT * FROM CHEESE 
WHERE (CHEESE_CODE='AAAAA' OR CHEESE_CODE='54321') AND CHEESE_NAME='EDAM'
ORDER BY CHEESE_CODE DESC, CHEESE_NAME DESC, CHEESE_COST DESC;
