If you are simply adding results of the same query but different results
then do not use UNION!!!
Run the same query three times with different parameters and simply add
the results together in a script.
Your ZSQL should look something like this
select distinct c.id_risque, c.libelle_risque, c.id_fiche, c.id_portee,
c.url_info
from (mots a join amotrisque b on a.id_mot = b.id_mot )
join risques c on b.id_risque = c.id_risque
where a.mot_MAJ like <dtml-sqlvar '%@@' + CRITERE + '@@%'> # or use
<dtml-sqltest> if you prefer
call this from a PythonScript
criteria = ['n'import quoi', 'depardieu', 'segolene', 'sarko']
results = []
for c in criteria:
results = context.ZSQLMethod(CRITERE=c)
This will work for fairly simple SQL but if you want to create your SQL
dynamically (and I don't think this is such a good idea) then you should
use a different template than ZSQL. With our mxODBC Zope DA you can pass
your SQL directly into the execute method of a DA connection object.
