Brian Diekelman commented on IBATIS-142:
----------------------------------------
I've been working on the java_release_2.3.0-677 tag. The trunk appeared to
have a lot of changes to it and I wanted a clean patch that could be applied to
the latest release.
The biggest problem thus far is how deep the actual PreparedStatement.execute()
is called:
SqlMapSessionImpl.insert()
SqlMapExecutorDelegate.insert()
GeneralStatement.executeUpdate()
GeneralStatement.sqlExecuteUpdate()
SqlExecutor.executeUpdate()
That last call prepares a PreparedStatement, calls execute(), gets the update
count, then closes it. Great for efficiency, bad if we need to get generated
keys from the PreparedStatement before it's closed.
My plan now is to add: afterExecute(RequestScope request, PreparedStatement) to
InsertStatement to be called by SqlExecutor.executeUpdate() if the
MappedStatement in the RequestScope is an instance of InsertStatement.
The majority of my time so far has been finding the most non-intrusive way to
add this without any unintended consequences affecting the otherwise stable
codebase. Hopefully I'll have a couple more hours to work on this over the
next few days, if not it'll be my project for next weekend.

> Project: iBatis for Java
> Issue Type: Improvement
> Components: SQL Maps
> Reporter: Brandon Goodin
> Priority: Minor
>
> public int executeUpdate(String sql,int autoGeneratedKeys)
> public boolean execute(String sql,int autoGeneratedKeys)
> public ResultSet getGeneratedKeys()
> We should provide support for jdbc auto generated keys retrieval. This is
> only available in Java 1.4. So, we would have to throw an
> UnsupportedFeatureException if 1.3 or earlier was being used.
