I am not exactly sure what you wish to do: is table1 simply a view based  
on a query of table2 and table3? It certainly sounds like it should be.  
But I am not sure if you update views in PostgreSQL that the original  
tables get updated.

You might wish to ask your question again in French as some of us will at  
least understand it like that.

Anway if you wish to update tables based on the results of queries in Zope  
you are probably best using a PythonScript to link the appropriate queries  
if this is not directly possible in SQL.


results = context.SQL.someQuery()
for result in results:
     context.SQL.anotherQuery(result) # you probably wish to pass a  
dictionary based on the first query in
