Hi Marios,
Maybe you might find this little sql idea useful:
db.execute('select foo from bar where foofield = %s or %s is null',
(foofield,foofield,))
When foofield == None, then everything matches.
Have a good day !
Christophe.
ps: I didn't check precisely the syntax, so, adapt ;)

I want to run a SELECT query on my database, in which there might be 0
or 1 or 2 WHERE conditions. The query runs in a function, e.g:
def GetContent(Title=None, Type=None):
return db.select('Content')
What I want to do is use the Title and Type parameters as WHERE
conditions, for example if only Title is specified, the query would be:
SELECT * FROM Content WHERE Title='The Title';
Or if only Type is specified, then the query should be:
SELECT * FROM Content WHERE Type='A';
But if both are defined then:
SELECT * FROM Content WHERE Type='A' AND Title='The Title';
I don't get how to create the 'WHERE ... AND ...' thing properly in
web.py, and Anand said in another message on the list that it's a bad
idea to build the query by concatenating strings.
