yes, there are a number of strange things about XML namespaces in SQL Transformer: one

What I usually do is mention the namespace in the root element and then prefix all
elements with the sql prefix.
I think it is clearer

Glad to hear this is not esql related :-)

From the information provided it is not immediately apparent to me what
your problem is. But from crude benchmarking I've done.. ESQL is
SIGNIFICANTLY faster than the SQLTransformer.. To experience this, use
apbench on the http://localhost:8080/cocoon/samples/poi/statetax.xls and
statetax2.xls
Jan,
well, I use SQLTranformer and not ESQL, for two basic reasons:
1) it does Stored Procedures just fine (and a year before ESQL did)
2) I don't like to be restricted to the generation step when it comes to SQL (as
happens using XSP)... though I have to admit I
dislike XSP all the way

Hi Joshua,
Did you perform the same test outside of cocoon? You should check how
long it actually takes for MySql to answer your query. If this is much
faster than those 130 ms, there might be a problem.
Also note that turning of debugging in Cocoon has given me a 10 times
speedup once.
The queries are definitely not taking 130ms outside of
cocoon.
What do you mean by turning off debugging? I've
changed the logging status to ERROR, and saw some
improvement. What did you turn off, and how did you do
so?
Thanks! :)

Can you put numbers on this? How much does it take to do the same
queries in a simple java program? (setup connections, start timer,
execute queries, stop timer)
And on another note: does it also takes

have you profiled the same queries using ESQL ?
It could be useful having such a benchmark.

it doesn't support two nested queries on the same level of nesting, as far
as I remember after looking at C2.0.1 sources. I don't think it's fixed.
Workaround is:
1. modify source codes
2. use XSP
I use XSP with ESQL
Can someone confirm this, and is there a workaround other
than chaining

Your example shows that it's possible to have one nested query inside
another one. But it doesn't show that you may have sibling nested queries.
as far as I remember, you can have only one child (nested query), but that
child can have one child too and so on. you can't have this:
