[Zope-DB] log sql generated

[Ben Avery]

Hi,

I'm developing a Zope site using relational tables rather than objects 
as zope products, and which involves a lot of quite complex sql.

(Zope 2.6.0, Python 2.1.3, Solaris 7, Oracle 8.1.5, DCOracle2)

Quite often in the development / debugging stage, the zsql doesn't work 
as I'd like, and I just get back an oracle error, like 'ORA-01722: 
invalid number', which doesn't help me much, as there are a number of 
places this could be happening.

Is there a way of logging the sql generated by the ZSQL methods, so I 
can locate the bug more easily?

or if I have to hack the source, which file would this be in?

TIA
