In the past I allways returned arraylist of hashmap and that works EXCLENT.
I now want to return xml. I saw some notes on xstream and it works but not
so well, I do not like the xml it makes.
Is there snipets or more ideas to help me?

Also, I wonder if iBatis is smart enough to create statments for each
type of a statment if there are mutiple?
or should I have 2 sqlmaps for 2 statments?

Or, you could even leave batch size to your dao:
sqlMap.startBatch();

So that is a good question: startTransaction or startBatch or both?
Which 1st?
Which is faster?

So reading last paragraph of sql map on page 32 docs.
I wrap the sql map in static methods anyway so that would mean that
if that sql map has only one statement, it could Q up all updates, and
then ever 3 secods restart the transaction.
It seems to make sense.

You can remap in sql w/ "as" or map the fields in XML.

No, you do not have to.
But sometimes you have to remap (in the map) the keys from form to db.
That would be extreme, my point was only that VO could and in my case
should be collections.
I mostly work w/ jTable and DataSource now, which work via "reflection"
(for each)

They are dynamic VO in the sense that one cad add a column in SQL or in

Most likely for "muti-insert" you want to use prepared statement (inside
a transaction), and I do so in Groovy (instead of iBatis, I use ibatis
for OLTP, Groovy for batch. Q: I wonder if people know why prepared
statement exists even. A: It's 1,000 times faster).

Don't work in iBatis, work in a sql query tool and hard code values

Also long term, "SQL for Smarties" (as opposed to Dummies) is a good book.

You can allways do a stored proc and force a plan.
