[Zope] Multiple SQL Updates

[Tom Jenkins]

Hi Craig
You can pass a list of things to a sql method and if you use a 
<dtml-sqltest ...> statement correctly the sql method will handle it nicely.

What you need to do is change your update query by changing the 
<dtml-sqlvar> to a <dtml-sqltest> and adding the 'multiple' attribute:

  update cmin_meeting
  set committee_code=<dtml-sqlvar committee_code type=int>
  where <dtml-sqltest meeting_ref column=meeting_ref type=int multiple>

I'll admit I haven't used this technique for updates but works fine for 
selects so I'm confident it will work for updates too.

Hope this helps,
Tom
