The first issue we've got is chr(0) appearing in input strings. Using Postres/Psycopg if we do:
<dtml-sqlvar variable type="string">
and variable contains a chr(0) then it will fail.
Obviously we can get round this by variable.replace(chr(0), '') on every variable before it goes in to the ZSQL method but that's not ideal. Would it be sensible to look at patching sqlvar or is this just a problem specific to Postgres?
The second issue we've got is with Booleans. It is quite annoying to have to do:
<dtml-sqlvar "str(variable)" type="string"> to insert Booleans. Also I think that some databases expect their Booleans to be other than 'true' and 'false' so introducing a Boolean quoting type would push this logic down to the DA rather than complicating the application.
We'd be willing to provide patches for both these issues if there's interest and agreement it's a sensible way to go.
