Question

The uncommented code below yields an OperationalError: near”?” while the commented lines works fine. What am I missing here?

g.db.execute('INSERT INTO ? (date,value) VALUES (?,?)', \
[session['user'],request.form['date'],request.form['value']] ) 

#g.db.execute('INSERT INTO '+session['user']+' (date,value) VALUES (?,?)', \
#                 [request.form['date'],request.form['value']] ) 

Answer 1

You can not use placeholders for column or table names. You can try this:

user = session['user']
data = request.form['date']
value = request.form['value']
g.db.execute('INSERT INTO {} (date,value) VALUES (?,?)'.format(user), (data, value))
