query with multiple joins and indexes stuck on "Copying to tmp table" - mysql

I have this query that doesn't run under odd circumstances. It's doing two joins, I have two indexes of the same name on two different tables (but this shouldn't matter). When I remove one of the indexes from either tables, the query runs fine. Something else that makes it run is removing the order by clause, but I definitely need that. When I run show processlist the state is stuck on "Copying to tmp table". The indexes I'm talking about are channelID.
the query
SELECT twitterTweets.*,
COUNT(twitterRetweets.id) AS retweets,
sTwitter.followers,
sTwitter.date
FROM twitterTweets
LEFT JOIN twitterRetweets
ON twitterTweets.id = twitterTweetsID
JOIN sTwitter
ON DATE(twitterTweets.dateCreated) = sTwitter.date
AND twitterTweets.channelID = sTwitter.channelID
WHERE twitterTweets.channelID = 32
AND type = 'tweet'
AND DATE(dateCreated) >= '2013-12-05'
AND DATE(dateCreated) <= '2014-01-05'
GROUP BY twitterTweets.id
ORDER BY dateCreated

So how do I make this thing run with both indexes in place? Do I have to ignore one of them?

Migrating an .sql database to WordPress

I have an SQL file for a database from an old custom blog CMS. I am trying to import the articles into WordPress but I am now stuck. So far, I have managed to isolate the table structures for the CMS (see below). I have also identified the columns that i need. These are (Post, Title, Date, Image, Category). Now I have to map these columns to some columns in the Wordpress schema somehow and that is where I am getting stuck.
Here is the SQL structure of the database:
CREATE TABLE `ads_ng_ads` (
`id` int(10) unsigned NOT NULL auto_increment,
`ad_type` enum('media','text','html') character set latin1 collate latin1_bin NOT NULL,
`media_type` enum('image','flash','other') character set latin1 collate latin1_bin default NULL,

PRIMARY KEY (`id`),

) ENGINE=MyISAM AUTO_INCREMENT=757 DEFAULT CHARSET=latin1;
CREATE TABLE `ads_ng_statistics` (

) ENGINE=MyISAM AUTO_INCREMENT=1381 DEFAULT CHARSET=utf8;

Assuming that you're using the latest WordPress version(4.9.1), you just need to create a script that will import all data to table wp_posts for example if you want to import as WordPress posts. Example: "Title" to "post_title", "post" to "post_content", etc.

multiple joins SQL query optimization

I have the following query :
SELECT
COUNT(DISTINCT a0_.id) AS sclr0
FROM
account a0_
INNER JOIN customer c1_ ON (c1_.account = a0_.id)
LEFT JOIN sf_user_data s2_ ON (s2_.user_id = a0_.id)
LEFT JOIN address a3_ ON (c1_.customer_address = a3_.id)
WHERE
a3_.city IS NOT NULL
resulting in the following output :
sclr0
+--------+
298279
with the following EXPLAIN :
id select_type table partitions type possible_keys key key_len ref rows filtered Extra
+--+---------------+-------+-----------+-------+--------------------------------------------+-----------------------+-----------+--------------------------------+-------+-----------+-------+

approximative number of rows in the tables :
account : 430000
customer: 430000
sf_user_data : 115000
address : 550000
Right now, this query is running in 3 seconds. Is there any way to speed it up ?

It seems like this simple amendment will be faster:
SELECT COUNT(DISTINCT a0_.id) sclr0
FROM account a0_
JOIN customer c1_
ON c1_.account = a0_.id
JOIN address a3_
ON c1_.customer_address = a3_.id
And if data integrity is important to you, consider switching to InnoDB.

Change LEFT JOIN address a3 to plain JOIN. That way, the optimizer could consider starting with address. And add INDEX(city) to address.
Currently, the EXPLAIN is showing hitting 405K rows in each of 3 tables. (1.2M total) With the above change, the optimizer would start with the city index, there by looking at, say 1K rows. After that, it would look up 1K rows in each of the other two tables. (3K total)
LEFT JOIN sf_user_data s2_ ON (s2_.user_id = a0_.id) seems to be totally useless; remove it. (Now down to 2K rows)
Don't blindly use (255), use reasonable numbers. In doing so, if identifier is not very big, make it the PRIMARY KEY and get rid of id.
It is extremely rare to have 6 different columns each being UNIQUE. I think you will run into business-logic trouble because of it.

How can I optimize view in MySQL?

Load take 60 sec, how can I optimize?

When SELECT the view detalle_full_ok all go right, but if SELECT the view detalle_full_ko go wrong.
View view detalle_full_ok is slow and view detalle_full_ko is fast. The problem is view detalle_full_ko retrieve wrong nombre_empresa field.
Rows:
afiliados(4700)
empresa(800)
contratos(4700)

First pare down the query to get only historico.Id_historico and historico.id_afiliado. That is, avoid any columns and tables you don't need in getting just the desired id pair:
SELECT DISTINCT Id_historico, id_afiliado
FROM ...
-- no GROUP BY or ORDER BY
Then use that as subquery to get the rest of the data:
SELECT lots-of-stuff
FROM ( the above select )
JOIN back to all the tables
WHERE ...
GROUP BY -- probably needed again?
ORDER BY ...
However, the GROUP BY does not include all the non-aggregate values in the SELECT, so it is probably 'improper' and will probably be flagged as an error with ONLY_FULL_GROUP_BY.

Laravel where method won't works correctly on my server but work right on my Mac

I have a weird problem, this line wont fetch any record on my server but works all right on my computer, mysql and php version are same, and when i cast id field to string it's work on server (Debian), but it is risky because i use where statement with id very much. this is the code:
$myAnswers=Questioner::where('id',$questioner_id)->first()->getLinkedAnsweres()->where("subject_id",Auth::user()->id);
and when i change it to this, it's work right (cast id to string):
$myAnswers=Questioner::where('id',$questioner_id)->first()->getLinkedAnsweres()->where("subject_id",(string)Auth::user()->id);
subject_id and user id are both unsigned_integer with same size.
How can i fix this problem? Should i overwrite where method? or is there any config which cast unsigned int to string in query?
thanks

Two MySql tables have correct indexes yet JOIN takes 9 seconds on small tables

mysql Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86_64) using readline 5.1
I am taking over a project. It is very old and the original programmer is long gone. No one has any idea why certain decisions were made.

If I remove this line:
join `wawa_title` `ot` on((`tlb`.`title_id` = `ot`.`title_id`))
The query speed drops from 9.5 seconds to 2.5 seconds. Not great, but a huge improvement.
And yet, both tables have indexes on table_id, so why would that line be a problem?
I notice that one table is InnoDB and the other is MyISAM. Would that have an effect?

Do not JOIN to tables that you don't use.
A JOIN often "explodes" the number of rows, then a GROUP BY like you have reels in the number of rows. To see this, leave all the JOINs there, but remove the GROUP BY. See how many rows you get.
To avoid part of that explosion, change
count(distinct `tlb`.`title_id`) AS `title_count`
to
( SELECT count(distinct `title_id`)
FROM `haha_title_list_to_books`
WHERE `ttl`.`id` = `title_list_id`
) AS `title_count`
and remove the current JOIN to tlb.
Mixing MyISAM and InnoDB should not have any direct impact on this SELECT. However, you should consider moving all of your tables to InnoDB.
