[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2575) Query results are mapped to object array incorrectly when there is column ambiguity and aliases are not used

Query results are mapped to object array incorrectly when there is column ambiguity and aliases are not used ------------------------------------------------------------------------------------------------------------ Key: HHH-2575 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2575 Project: Hibernate3 Issue Type: Bug Components: query-sql Affects Versions: 3.2.2 Environment: Hibernate 3.2.2 + MySQL 5.0.22 + MySQL Connector/J 5.0.5. Reproduced with HSQLDB 1.8.0.7. Reporter: Mike Hoeffner Priority: Minor Attachments: ResultsNotEffectedByAliasesTest.java I had a SQL (not HQL) query that basically looked like this: select a.name, a.seq, b.name, b.seq from foo a, foo b; and I noticed that the results obtained through list() -> (Object[]) get(i) -> row[0], row[1], row[2], row[3] did not correspond to what I saw when manually running the query without Hibernate involved. row[2] always had the same values as row[0] and row[3] always had the same values as row[1]. When I tried adding aliases so that it became: select a.name as a_name, a.seq as a_seq, b.name as b_name, b.seq as b_seq from foo a, foo b; then the results matched what I expected. So having aliases in the SQL modified the results that were returned even though I was looking up the value from each column by its index / position instead of by its name / alias. Attached is a test case that will reproduce this. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
