I'm not sure why this should *crash* zope, but you can do it with a much
simpler query and a little DTML coding. The following should work
(UNTESTED):
Z SQL Method (named sql_query):
select codigo, nome, tipo
from cad_exportacao;
DTML Method:
<select>
<dtml-in sql_query>
<option value="&dtml-codigo;"
<dtml-if "tipo=='E'">Selected</dtml-if>>
<dtml-var nome></option>
</dtml-in>
</select>
