[Zope] SQLTEST is case insensitive?

I am fairly certain, though I cannot find the ANSI document I'm
looking for on the web, that double quotes is OK with the standard,
and shouldn't break other databases, though it would break
PostgreSQL code.

Well, were would I add this?  I'm not familiar enough with the Zope
Architecture to actually add this feature to Zope Proper.
Especially without risking damaging everyone else's objects.

Ahh...okay.  I guess that makes sense.  I just prefer to do it right
the first time....best practises and all that.

You don't need the single quotes since ID is an integer.

I'm exaggerating.  It just negates the dtml-sqlxxxx specials.

<dtml-sqlgroup where>
  <dtml-sqltest ID type=int optional>
<dtml-and>
   "val_Protocol"."ID" = "URL"."val_ProtocolID"
</dtml-sqlgroup>

If I make that:
<dtml-sqlgroup where>
   "URL"."ID" = <dtml-var ID sql_quote>
<dtml-and>
   "val_Protocol"."ID" = "URL"."val_ProtocolID"
</dtml-sqlgroup>


Then ID cannot be optional.  I can't use this object as a 'list all'
solution.  Isn't that the whole point of the dtml-sqltest tag?

Does anyone have some good NORMALIZED (say 3rd-4th normal) database
examples of using ZSQL Methods and database adapters?  Just a really
good example would be great.

Ciao!
