There is one exception though, when you want to have a special indexing like for invoice or orders, look at it from the getNextInvoiceId and
getNextOrderId services definitions
Beware of https://issues.apache.org/jira/browse/OFBIZ-3557

Hi wulei
You can use either <sequence-id-to-env ...> in minilang or
delegator.getNextSeqId(...) in Java. The id sequence numbers are
stored in an entity SequenceValueItem.

Taher,
Thanks so much for your opinions! Could anyone help describe 'Sequences'
more, on details of how to leverage this feature to make an column
auto-incremented? Thanks in advance.

Hi
Two answers come to mind:
1- you do not need this feature because it exists at the application level
which you can also customize with services. Sequences are one such place.
2- the whole purpose of the entity engine is to abstract the databases and
provide independebce at the application level.
So my opinion is not to focus on databases ever for any kind of logic. My
2
cents.

Guys,
We all know lots of databases support auto-increment columns, how can we
define such columns in ofbiz's entitymodel.xml file? Or other means to
implement this ?
