When I am trying to rum query I find error like
#1267 - Illegal mix of collations (latin1_general_ci,IMPLICIT) and (latin1_swedish_ci,IMPLICIT) for operation '='

You don't show your query, but i expect you're doing a where somehow with an '=' in there. Now your default collation seems to be swedish, and your 'blockedcompanies' table has a collation to latin1_general.
The error says "implicit", so you're not doing something with collation in your query. Now you have to different collation being compared. You've got to change that using COLLATE
check this: http://dev.mysql.com/doc/refman/5.0/en/charset-collate.html
when you create the table empregistration, change the final line from
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=214 ;
to
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci AUTO_INCREMENT=214 ;
and your query should start working.

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:

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.
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 :

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.
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
