Francesc
Many thanks for your quick answer, I made a test without Psyco and it
works, but the problem that I have, psyco is a vital part of my
project.
I run the same test, but iterating over all the rows and I making
inside the loop an explicit condition and it works with psyco
Are there some alternative way to iterate over some rows in a table
that satisface a condition and the posibility of modify the table
values?
regards
German
