in thread Overflow of $DBI::rows

I'm trying to avoid doing the separate SELECT COUNT(*). What we are performing is:
my $sth = $dbh->prepare("UPDATE ...;") or die DBI::errstr; $sth->execute or die DBI::errstr; printf "Rows: %s\n", $sth->rows;
and $sth->rows is returning a negative number.

    DanEllison:

    D'oh! Sorry about that. You were clear, I just had a brain glitch.

    I don't know a way to fix that, but I took a quick look at the ODBC Programmers Reference at msdn, and they're mentioning that the MDAC 2.7 ODBC libraries allow 64-bit values for the SQLLEN data type (used by SQLRowCount). If you're on a Windows platform, it might be sufficient to make sure you're using the latest ODBC libraries. (Of course, the Teradata end might still be using the 32 bit types, in which case you're probably out of luck.)

[choroba]: Morning!
[Corion]: Hi choroba, Discipulus!
[Corion]: Yesterday I've been mulling over how to best generate HTTP requests from permutations of values but I haven't found a nice API for passing in the "template" of the HTTP request yet. I guess I'll have to do a SoPW for that
[Corion]: The API itself will basically be my $iter = generate_http_requ ests(method => 'GET', url => '/settings/:name', headers => ???, get_params => ['foo','bar']), but I'm not sure how to parametrize values in the headers and how to specify lists of ...
[choroba]: On the other hand, lots of options to receive the requests :-)
[Corion]: ... values to be used. For example, I think for headers, one would want to have various kinds of Content-Encoding headers, but for the get_parameters one would have various kinds of Bobby Tables
[choroba]: What about [metadoc:// Algorithm::Loops]?
[Corion]: choroba: Yeah, but handing off the request to Dancer,Plack, Mojolicious,LWP is easy once I have the data filled into some structure ;))
[choroba]: Algorithm::Loops
[Corion]: choroba: I'm using that to generate the permutations, but I don't know how the user can pass the intended values to my function in a sane way
