found this on web:
"So in summary, for tables with autoincrement primary keys ->find requires that
you provide the primary key in the query, and ->create requires that you don't
- this means that you cannot pass the same query hash to both methods and this
is what ->update_or_create does."
so that means my update_or_create is never going to work on an empty table???
really? I am stuck pl help.

Subject: [Dbix-class] DBIx how to update_or_create a table with primary index
is autoincrement ? getting erroneous data
friends,
I have a Table to update (empty right now), and the regularly 'update' existing
info with changes AND add any new record which come up.
source data is coming from file. one record per line.
my @my_arr; #has 500 uniq entries
$schema->resultset('Mytable')->update_or_create(
{
field1 => $my_arr[0],
field2 => $my_arr[1],
field3 => $my_arr[2],
...
},
{key =>'primary'} #field_id, auto increment value this field is NOT
supplied in variables above.
);
What is happening is: DBIX is first adding the 'first' record, then updating it
with consecutive records!!! it is not creating a fresh record for any record in
the file. so after it finishes running, I am left with one record in Table
which is updated 500 times, and has the last record in file as the table record.
how to fix this?
