[Graeme Gillies (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-1928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664678#comment-12664678 ] 

Graeme Gillies commented on TEIID-1928:
---------------------------------------

Doing a query against the database itself we can see

{noformat}
mysql> select distinct(changed) from History order by changed asc limit 3;
+---------------------+
| changed             |
+---------------------+
| 0000-00-00 00:00:00 |
| 1989-11-08 08:00:00 |
| 1990-06-15 10:00:00 |
+---------------------+
3 rows in set (0.09 sec)
{noformat}

That the field has got values set to "0000-00-00 00:00:00". So it looks like the code that does the conversion is failing somewhere? It seems to work fine via JDBC, just fails with the PSQL layer.
