[Catalyst] wrong generated SQL
Can someone tell me why this:
my $rs1 = $c-model('ORANGES::File')-search({'report_id' = $rptcode}, {
rows = 1,
page = $page,
});
Results in the following SQL?
SELECT COUNT( * ) FROM HCDB_TEST.FILE me WHERE ( report_id = ? ): '541861'
When it used to create SQL that actually pulled the fields. It was working
and I have had to re-create several of my template files which is how I
discovered this. I made no changes to this code and suddenly it is
generating this count(*) instead of getting the columns.

you probably used something like .all, .first or a while loop with
.next on your resultset in your template.
unless you do so again, no actual results are going to be fetched from
your database
you might just as well use find instead of search if you are only
going for one row

siggen.pl: Segmentation Fault
I did use .next in my template, but this code should (and did) return 4
rows. I am also using a pager on the resultset, which still shows 4 pages
when I display the template, however I get no column data, just the count.

Re: [Catalyst] wrong generated SQL
The count query is issued to get a total row count for the pager. In your template, is it possible that you currently just display the number of results from the pager instead of the actual resultset data? As soon as you ask the resultset for data you should see another query being issued for the row data. What does your template code look like?
