### works ####
newcur.execute (  """ INSERT INTO events (id1,id2)   VALUES  (%s,%s);
""" , (rs[1],rs[2]))

### works not
newcur.execute (  """ INSERT INTO %s_events (id1,id2)   VALUES  (%s,
%s); """ , (table_name,rs[1],rs[2]))

### works but is not really perfect: None from rs list result in
"None" instead of NULL.
newcur.execute (  """ INSERT INTO %s_events (id1,id2)   VALUES
('%s','%s'); """  %  (table_name,rs[1],rs[2]))
