Subject [jira] Commented: (TORQUE-128) remove autoIncrement attribute of column element
Date Fri, 10 Sep 2010 07:21:34 GMT

    [ https://issues.apache.org/jira/browse/TORQUE-128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12907916#action_12907916

Thomas Vandahl commented on TORQUE-128:
---------------------------------------

I tend to disagree. If I'm not mislead, I can have columns which are primary keys but have
no auto-increment flag on (or no associated sequence, for that matter). N:M-tables are a typical
example or tables with compound primary keys. How would you handle those? As I see it, this
modification would impose a serious limitation on the way you describe database schemas with
Torque.

Besides, Torque handles sequences just fine with database systems that support them.

> In the 3.3 schema, the id method for a column is determined by the idMethod attribute
of the table, the defaultIdMethod attribute of the database and the primaryKey attribute of
the column. This is sufficient for determining the idMethod.
> However, in the 3.3 schema, there is still the autoIncrement attribute which kind of
overrides the settings outlined above. There is no such equivalent for sequence generation,
thus the attribute is bad for database interoperability.
> Therefore I'd suggest to remove this attribute with no replacement. The consequence would
be that it would no longer be possible to have auto_increment on columns which are no primary
key (but again, torque supports no such feature for sequence generation).
