Booger has asked for the wisdom of the Perl Monks concerning the following question:
Hello folks:
I'm using MySQL and have some tables where I can't use auto_increment on the primary keys (for some weird reason I won't bother to explain) and want to control the sequence of said primary keys manually.
Ex: a user submits a form having a couple of input fields and I receive them in a hash $r->{params} (yes - I'm using Maypole).
The piece of code that creates a new row in the database according to the form data looks something like this:
$r->{params}{$self->primary_columns} = &some_value; $h = CGI::Untaint->new(%{$r->{params}}); $obj = $self->create_from_cgi($h);
Which to me, looks fine.
Apparently it's not.
Whenever this portion of code gets executed I receive the following error:
Can't insert new Library::Book: DBD::mysql::st execute failed: Column 'id' cannot be null [for Statement "INSERT INTO book (name, aut +hor, id) VALUES (?, ?, ?)"] at /usr/local/lib/perl5/site_perl/5.8.5/DBIx/ContextualFetch.pm line 51, +<GEN2> line 7. at /usr/local/lib/perl5/site_perl/5.8.5/Class/DBI/FromCGI.pm line 246
I've searched and searched and can't seem to discover what exactly is causing the manually set primary key to be ignored.
Any suggestions or comments would be greatly appreciated. Thanks!
