Hi Simon, Thanks for your answer, I suppose by ", ..." in the create table command you mean that I should explicitly specifying each column, which is exactly what I didn't want to do in the first place.
By your response I guess that there is no other way of doing it then.... Well I will test and decide which method from yours or the copy method from the sqlite website suit me the best. Thanks for your help.... In the mean time if someone else has an other idea, it will be welcome....
