Question2Answer Q&A - Recent questions tagged queries

For many people, it's taking longer than planned to post new queries on my website.

Hello Team

We're experiencing some issues with this website; it's taking a while to add new questions. I tried the standard suspects and disabled every plugin on the template, but nothing changed. even thoroughly cleaned Cloudflare's cache, but unfortunately, nothing worked.

Thus, I made the decision to slightly speed up the server. upgraded to a plan that functions as follows:

180 GB NVMe 4-based CPUs

Memory: 8 GB; Bandwidth: 6 TB

Hopefully not, however the problem still exists. Are there any bright minds out there that have ideas about how to approach this? Using Q2A version 1.8.8, if that adds any significance. We greatly value your wisdom!

Thank you

As many hackers are making large number of search queries on my website and the search results are successfully indexed in google search console, I need to disable search function.

I have blocked all ip ranges as well as remove search button from the website, but it is still happening by hackers.

Please help.

Improving the speed of a query with qa_edit_history

Mon, 29 Jul 2019 07:47:49 +0000

I am using this query:

SELECT COUNT(*) FROM `qa_edit_history`
WHERE DATE(`updated`) = CURDATE()

It takes:

598.97 ms - 1 row - 1 column

I would like to speed it up.

Can I do so by adding certain indizes to the table?

How to preserve NULL value with q2a queries?

Thu, 21 Dec 2017 04:19:27 +0000

As far as I can see, this query:

qa_db_query_sub('UPDATE `qa_users` SET '.$field.' = $ WHERE userid = # ',
$value, $userid);

insert a string for $field when the passed $value is NULL.

How can I force the NULLing of the field?

----

Update:

Seems that I had a trim($value) somewhere that made the NULL an empty string.

So NULL is set in the DB using the query above!

How to speed up queries on "qa_eventlog"?

Sun, 17 Sep 2017 17:47:38 +0000

From my server logs, the slow notifier:

# Time: 2017-09-17T19:48:06.840513Z

# Query_time: 8.226348 Lock_time: 0.000102 Rows_sent: 1 Rows_examined: 435073

SET timestamp=1505677686;

SELECT datetime,ipaddress,handle,event,params
FROM `qa_eventlog`
WHERE UNIX_TIMESTAMP(datetime) > 1505677527
AND (`event`='q_post' OR `event`='a_post' OR `event`='c_post' OR `event`='a_select')
ORDER BY datetime DESC
LIMIT 10;

Is there any ways how I can speed up the table or to optimize the query? 8.2 seconds is huge!

When to use function qa_db_select_with_pending() ?

Tue, 29 Apr 2014 08:43:15 +0000

From qa-db-selects.php it can be read:

    Return the results of all the SELECT operations specified by the supplied selectspec parameters, while also
   performing all pending selects that have not yet been executed. If only one parameter is supplied, return its
   result, otherwise return an array of results indexed as per the parameters.

Can somebody clarify when we should use this function?

Thanks
Kai
