Avoid using @@Identity and instead use Scope_Identity().
Here is a blogg that summarises the point:

Notwithstanding the OP's issue . is there any sensible way of preventing
this? Ie. how to detect connections are being returned to the pool without
them properly ending transactions?
Is it even possible?

Hi Brad,
Have a look at the WITH statement (it is ANSI specified) and CTE's (common
table expressions). Here is an example with SQL 2005.

I am sure the logic will also work off Oracle versions that support the WITH

As I understand it, SqlMapClientImpl (SqlMapClient) hides or wraps the primary
JDBC object, Connection. So, we can essentially do everything with
SqlMapClient that we can with JDBC's Connection object (including starting,
commiting or aborting transactions). However, with iBatis, we don't

All connectins and transactions are managed using thread local
storage, so each thread has it's own connection, etc..
(Thanks Larry!)
Ok. Understood. So, each time a new thread that uses SqlMapClientImpl is
spawned, a Connection object is removed
Larry:
Almost, but not exactly. ;-)
The connection does not remain with the thread for the life of the
thread, but rather the thread gets the connection from the pool (the
pool marks it as used so no one else gets it), then uses it, then
closes it (which just tells the pool that it can

Hi Clinton - thanks for responding.
SimpleDataSource has served us very well over the years, with very few
changes. I'd like to redo the interface at some point (currently
yucky property based config), but the implementation seems to work
well. It's a synchronous pool that doesn't spawn

You can delay parameterClass to runtime already -
you don't need to specify it at configuration time.
Yes, of course:

Abdullah,
Why do you want to use Arrays[]? Lists are better because they can grow
and can always be converted into an array.

Does iBatis support resultsets as arrays or the population of beans that
