Hi

Sorry - haven't followed this thread, but I have just filed a bug report
on this problem. I guess you are using 3.23.4. If you show fields from
tablename, then your auto_increment/primary key field has NULL as
default - even though you state not null in create table.

I got the same error in my application
ERROR 1062: Duplicate entry '1' for key 1

when I tried to insert into the table and expecting mysql to
auto_increment it automatically.
