[Zope-DB] cant perform insert on mysql

[Harry Wilkinson]

It looks to me like you're not submitting the request containing all your 
data to the ZSQL method, just calling it.  I am not sure how dtml-call works, 
and I am not that familiar with DTML's namespace handling (I have avoided 
DTML as much as possible in favour of Python/ZPT) but perhaps the data are 
not available when you use dtml-call like that.

For a quick hack solution, if it's the dtml-call that's the problem, you 
could pass the REQUEST to the ZSQL method explicitly, something like this 
(you'll have to check the semantics, this is off the top of my head):

<dtml-call "sqlInsertRequest(REQUEST=REQUEST)">
