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

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=31435#action_31435 ] 

Steve Ebersole commented on HHH-3125:
-------------------------------------

BigDecimal with a scale of 0 would approximate an integer (zero significant digits right of the decimal).

Floating point values as a PK makes zero sense.  JDBC type mapping suggests that both DECIMAL and NUMERIC SQL types be mapped to BigDecimal which is why the driver is reporting them that way.  Really these columns should be defined as INTEGER or BIGINT which are the SQL defined integer datatypes.

> Currently with using BigDecimal as entity id is thrown exception " this id generator generates long, integer, short or string" - class "IdentifierGeneratorFactory".
> Is there possibility to add BigDecimal support for id generator?
