BigDecimal support for id generator from DB sequence
----------------------------------------------------
Key: HHH-3125
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3125
Project: Hibernate3
Issue Type: New Feature
Environment: Hibernate 3.2, Oracle 10
Reporter: Tomas Rada
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?

Resolution: Rejected
I don't see the benefit.
First, how can a sequence value be a floating-point value in the first place?
Second, IdentifierGenerator is an extension point; writing a custom impl that delegated to
the standard sequence generator and wrapped the sequence result in a BigDecimal should be
trivial.

Graham Collinson commented on HHH-3125:
---------------------------------------
An oracle column with Number(22,0) isn't floating point but is still reversed as a
BigDecimal. BigDecimal support in IdentifierGeneratorFactory would seem to make sense in
this case. Unless the sql type is being incorrectly reversed. Perhaps it should be a
BigInteger instead?
I will be able to use a GenericGenerator to get round this.

Dan commented on HHH-3125:
--------------------------
Can you please give some more details as to how that would be accomplished. I am using
Sybase / JPA via JBoss 4.2.2. I would like to have my PK fields mapped to BigInteger in
the JPA entity and then implement IdentifierGenerator but, I'm not sure how to hook it
all up. Pleas advise.

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.

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

------------------------------------
I vote that +1 BigDecimal should be allowed, but Hibernate must force it has no precision.

-------------------------------------------
Steve, could you share an example how to use IdentifierGenerator as an extension point so
that it works universally well in Oracle, MySQL and Sybase with BigDecimals?

-------------------------------------
Please try this out and report any issues back against HHH-4905.
@aleksander Well IdentifierGenerator is an interface. when it is asked to configure(...)
itself it is given all the information you could need. I am not going to do the work for
you. There are plenty of IdentifierGenerator implementations you could look at as
examples of what you might need to do for your situation.
