Q2A Performance Queries Issue

Mon, 06 Sep 2021 09:27:43 +0000

I try to log all the queries when post a new question and there are approximately 80 queries. Some queries take a lot of time such as:

INSERT INTO qa_contentwords (postid, wordid, count, type, questionid) ~ 2s

INSERT INTO qa_titlewords (postid, wordid) ~ 1s

INSERT INTO qa_sharedevents (entitytype, entityid, questionid, lastpostid, updatetype, lastuserid, updated) ~ 1s

So it takes ~10s for posting a new question. Do you guys face up with this issue? And how to solve this problem?

Prevent sql injection in q2a custom php form ?

Tue, 31 Mar 2020 19:33:04 +0000

This is how i store data in mysql via php form. I know its security risk.

Examples - $price = $_POST['price'];

$price = array_key_exists('price', $_POST) ? $_POST['price'] : "";

and sql query is -

$insertqry = qa_db_query_sub("INSERT INTO test_table (title, price) VALUES ('$title','$price')");

How should i post data in latest php 7 and above version ?
I think escape string is deprecated or outdated.

Thanks for your help !

SQL query help

Fri, 03 Nov 2017 03:42:57 +0000

I was trying to count the userpoints per category. The query works if I use a single level of category match. But if I try to get the points on subcategories too, the query gets too slow as it runs on uservotes table having thousands of rows. Is there a better way to do this? The current query is as follows with part of it coming from points update function in the core.

$catfilter = " and (userid_src.categoryid = b.categoryid or userid_src.categoryid in (
select categoryid from ^categories where parentid = b.categoryid)
or userid_src.categoryid in (
select categoryid from ^categories where parentid in (select categoryid from ^categories where parentid = b.categoryid)))";

$query1 = "insert into ^catpoints (categoryid, userid, points) (select b.categoryid,#, ".
$calculations['aselecteds']['multiple']."*(select ".$calculations['aselecteds']['formula'].$catfilter.")+".
$calculations['avoteds']['multiple']."*(select ".$calculations['avoteds']['formula'].$catfilter.")
as points
from ^categories b) on duplicate key update ^catpoints.points=points";

Data not showing up after imported sql

Mon, 12 Sep 2016 07:51:19 +0000

I have an OLD version of Q2A, which I'm trying to upgrade to the latest. But I am also doing the wordpress integration.

So my steps have been:

1) Installed wordpress on subdomain

2) Integrated SSO with wordpress and fresh installation of Q2A on a different subdomain (worked)

3) Exported & Imported old Q2A database to new integrated database, but problem is none of the questions are showing up, just the categories e.g. "blah blah (50)". Even tried it on the same domain that the old questions are on, no luck.

Any help? Thanks!

I am currently using the following query to display Questions in a separate Wordpress instance.

or die(mysql_error());

Is it possible to ONLY select questions where there is an answer has been provided?

Many thanks in advance.

How to do not add ' character when using parameters with sql query

Fri, 14 Feb 2014 08:22:58 +0000

Sometimes when I used qa_db_query_sub() function to create a sql query, I like to use columns as parameters

    $sql = "select # from ^users";

    qa_db_query_sub( $sql, 'id' );

The problem here is Q2A adds ' character to parameters and make

    "select 'id' from db_users"

That is wrong. I don't want those characters. How could I get rid of them?

Inserting a comment into Q2A via SQL

Sat, 01 Jun 2013 11:26:15 +0000

How would I go about structuring a SQL INSERT to create a comment in the Q2A database?

From my research so far, I'm working out that comments in the SQL are stored in qa_posts, e.g

INSERT INTO qa_posts VALUES ('$postId', 'C', (lots of other data), 'Comment message.', NULL, NULL);

Add categories via SQL

Wed, 30 Jan 2013 07:05:34 +0000

Hello,

is there any good way to import categories from csv file?

Mine only idea was by INSERT to database => _categories

INSERT INTO `_categories`(`categoryid`, `parentid`, `title`, `tags`, `content`, `qcount`, `position`, `backpath`) VALUES ([value-1],[value-2],[value-3],[value-4],[value-5],[value-6],[value-7],[value-8])

but I'm not sure is this way is Ok.

Can someone be so kind and confirm, if I will do such Insert I will not should have trouble with them?
