[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3125) BigDecimal support for id generator from DB sequence

[Dan (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31448#action_31448 ] 

Dan commented on HHH-3125:
--------------------------

The underlying issue that I am having is Sybase specific which is; If you use Long or Integer than the underlying index is not used due to a type conversion under the covers which means that a full table scan is taking to do a look up by PK!. You have to map to BigInteger or Big Decimal to actually get it to use the index. I tried to go the IdentifierGeneratorFactory  but, ended up just using the @Type annotation approach as laid out here: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1936

> Is there possibility to add BigDecimal support for id generator?
