I would like to create a query that returns a column with an integer
1 through (row_count) to use as the index while used in conjunction with
DBI's selectall_hashref($sql,$key) function. In the past I'd usually just
write a wrapper around selectrow_hashref and put all those results in an
array. I don't know why DBI doesn't include a function like this.
if I could extract a pseudo column from the query itself with the result
order number, I could just use that as the key in selectall_hashref and sort
the results by key.
Is there a built-in function that returns the current row #?
select foo from bar;
row#;foo
----;-----
1;foodata1
2;foodata2
3;foodata3
4;foodata4
so I can pump it into:
my $hashref = $dbh->selectall_hashref($query);
print $hashref->{1}; # prints 'foodata1' etc
Or am I missing something and there is a way better way to do this...?
Sincerely,
Kenji
