Stop query through pdo

I wish this helpful for you The main problem here is to share PID between your async request that generates the report and the script that should stop it.
You can get your PID using:
code :
    $stmt = $dbh->prepare("SELECT CONNECTION_ID()");
    $pid = $stmt->fetchColumn();

if (!include __DIR__ . '/vendor/autoload.php')
    die('You must set up the project dependencies.');

use Fuz\Component\SharedMemory\SharedMemory;
use Fuz\Component\SharedMemory\Storage\StorageFile;

// your intializations here

$storage = new StorageFile("/tmp/shared.{$user_id}.sync");
$shared = new SharedMemory($storage);

if (!isset($_POST['cancel_request']))
    $stmt = $dbh->prepare("SELECT CONNECTION_ID()");
    $pid = $stmt->fetchColumn();

    $shared->pid = $pid;

    // your long query here

    // kills pid
    $pid = $shared->pid;
    if (!is_null($pid))
        $dbh->exec("KILL {$pid}");

it should still fix some issue I don't know Perl, but it seems you are not committing the data and thus Perl does not see the updated value.
Another possibility could be that Perl changes the isolation level to repeatable read. If that was the case, you will need to end the current transaction in Perl (even a SELECT is a transaction!) by issuing a commit or rollback (from within Perl) in order to see the updated value.

seems to work fine Eventually I had to use a solution that does not know if it's the best, but it was a mixture of things:
I was already using something like this to save the results of the querys in CSV files and then lift them into a session variable.
How can I stop SQL Server query from returning multile rows for the same item ID in this query

I wish this help you You can use a Common Table Expression. This will return the first occuring item_id.
code :
    SELECT *, ROW_NUMBER() OVER(PARTITION BY item_id ORDER BY abs_date) Rank
    FROM tblAbsentee
WHERE Rank = 1

this will help This is a known problem with Solr 5 and up, since it no longer rewrites the position for each token when the stopfilter is invoked. This issue, with a few suggestions of how to fix it, is tracked in SOLR-6468.
The easiest solution is to introduce a mapping char filter factory, but I'm skeptical to it changing characters internally in a string. (i.e. "to" => "" also affecting veto and not just to). This can possible be handled with multiple PatternReplaceCharFilterFactories instead.
code :
package filters;

import java.io.IOException;
import java.util.Map;

import org.apache.lucene.analysis.TokenFilter;
import org.apache.lucene.analysis.TokenStream;
import org.apache.lucene.analysis.tokenattributes.PositionIncrementAttribute;
import org.apache.lucene.analysis.util.TokenFilterFactory;

public class RemoveTokenGapsFilterFactory extends TokenFilterFactory {

    public RemoveTokenGapsFilterFactory(Map<String, String> args) {

    public TokenStream create(TokenStream input) {
        RemoveTokenGapsFilter filter = new RemoveTokenGapsFilter(input);
        return filter;


final class RemoveTokenGapsFilter extends TokenFilter {

    private final PositionIncrementAttribute posIncrAtt = addAttribute(PositionIncrementAttribute.class);

    public RemoveTokenGapsFilter(TokenStream input) {

    public final boolean incrementToken() throws IOException {
        while (input.incrementToken()) {
            return true;
        return false;

fixed the issue. Will look into that further I have set up up a products table with a "look" column, in this column it can be in multiple ranges such as "1,6" all comma separated in the table column.
