I am using dbi:odbc and I am trying to grab 11 rows out of my Data Base. I want these eleven rows to be newer than a certian DATE and TIME. But if there are 20 rows newer than the date and time I state, I want to get the oldest 11 rows, ordered by DATE and TIME. I have done this with ASP by using a TOP statement inside a nested select statement together (ordering the nested select asc and the outside select by desc), but I was unable to get this to work in my perl code. I was wondering if there is a way to grab 11 rows, the way I want to (without ordering them by DATE and TIME asc ), because there could be cases when there will be less than 11 rows returned.
use dbi;
my $dbh, $sth;
my ($sport, $import) = @_;
my ($path) = "d:/text/time/" . $sport . ".txt";
open (text, "$path") or die "couldn't open!\n";
my (@text) = <text>;
my $d = $text[0];
my $t = $text[1];
my $a = $text[2];
$dbh = DBI->connect("dbi:ODBC:burlee","spacecitysports","houston34")
+ or die die "Can't open connection\n";
$sth = $dbh->prepare("select *
from DATA_DB_ENTRY__ASTROS_STAGING
where TS_DATE >= '" . $d . "'
and IMPORTACE = '" . $import . "'
order by TS_DATE asc, TS_TIME asc
");
$sth->execute();
this is an example of how I was able to get the info queried out but I can not use this if there is less than 11 rows returned.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
