I am working with MySQL server, where I need to write/read some content contains latin characters like čćšž, but for some reason my database can not store č and ć characters.
As far as I know those characters should belong inside utf8_general_ci.
I added this to my.cnf file:
[mysqld]
init_connect='SET collation_connection = utf8_general_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_general_ci
skip-character-set-client-handshake
Take a look at this picture with all encoding:
I use SOURCE command to import my database to server. Here is content of SQL dump:
SET NAMES utf8;
/*!40101 SET SQL_MODE=''*/;
/*!40014 SET #OLD_UNIQUE_CHECKS=##UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET #OLD_FOREIGN_KEY_CHECKS=##FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET #OLD_SQL_MODE=##SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET #OLD_SQL_NOTES=##SQL_NOTES, SQL_NOTES=0 */;
CREATE DATABASE /*!32312 IF NOT EXISTS*/`horoskopium` DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

How I can solve this?
You should use utfmb4. I'm pretty sure it'll fix this.

Utf8_general_ci or utf8mb4 or...?

I have an application where I use a QSqlQueryModel and a table view to view some data from a mysql database.
I created the database using phpMyadmin and wrote a Python script to read Arabic data from Excel sheets and insert it into the database.
Everything works well on Linux, but when I switched to Windows, the application can't seem to encode the Arabic words correctly.
This is how it looks like for the avilable data:
صودق بالعلاج ةالمتابعه بقسم(المخ والاعصاب)
...and when I insert new data using Qt, the data shows as question marks (?).
Here's the MySQL dump for the database:

Note that the old data inserted on Linux is shown properly on phpMyAdmin.
See this fragment from QTextCodec::codecForLocale documentation:
On Windows, the codec will be based on a system locale. On Unix systems, the codec will might fall back to using the iconv library if no builtin codec for the locale can be found.
This could explain why you saw the correct arabic characters on Linux, but not on Windows.
As an alternative in this case, you can "force" the codec using the following instruction in your main.cpp:
QTextCodec::setCodecForLocale( QTextCodec::codecForName("UTF-8") );
PS: Don't forget the #include <QTextCodec> directive.
I'm trying to import database dump into my mariaDb 10.2.6 database.
It's a Magento 2 database.
There is this table import:
# Dump of table store_website
# ------------------------------------------------------------
DROP TABLE IF EXISTS `store_website`;
CREATE TABLE `store_website` (
`website_id` smallint(5) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Website Id',
`code` varchar(32) DEFAULT NULL COMMENT 'Code',
`name` varchar(64) DEFAULT NULL COMMENT 'Website Name',
`sort_order` smallint(5) unsigned NOT NULL DEFAULT 0 COMMENT 'Sort Order',
`default_group_id` smallint(5) unsigned NOT NULL DEFAULT 0 COMMENT 'Default Group Id',
`is_default` smallint(5) unsigned DEFAULT 0 COMMENT 'Defines Is Website Default',
PRIMARY KEY (`website_id`),
UNIQUE KEY `STORE_WEBSITE_CODE` (`code`),
KEY `STORE_WEBSITE_SORT_ORDER` (`sort_order`),
KEY `STORE_WEBSITE_DEFAULT_GROUP_ID` (`default_group_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Websites';
LOCK TABLES `store_website` WRITE;
/*!40000 ALTER TABLE `store_website` DISABLE KEYS */;
INSERT INTO `store_website` (`website_id`, `code`, `name`, `sort_order`, `default_group_id`, `is_default`)
VALUES
(0,'admin','Admin',0,0,0),
(1,'my_website','MY_WEBSITE',0,1,1);
/*!40000 ALTER TABLE `store_website` ENABLE KEYS */;
UNLOCK TABLES;
This fails giving me a duplicate key 1 error. Obviously it tries to insert the value 0 as a new increment which would be 1 but that is already in the table.
This error appears even though these options are set:
/*!40101 SET #OLD_CHARACTER_SET_CLIENT=##CHARACTER_SET_CLIENT */;
/*!40101 SET #OLD_CHARACTER_SET_RESULTS=##CHARACTER_SET_RESULTS */;
/*!40101 SET #OLD_COLLATION_CONNECTION=##COLLATION_CONNECTION */;

/*!40111 SET #OLD_SQL_NOTES=##SQL_NOTES, SQL_NOTES=0 */;
As far as I know the InnoDB engine does not support the NO_AUTO_VALUE_ON_ZERO mode. It should be supported by MyISAM though.
Note that using zero as a key in a auto_increment column is not a recommended practice, so it is advisable to avoid it. Is it an option to import the data to MyISAM-tables, do whatever to change the zero-keys to positive numbers and then switch to InnoDB?
This mysql query is extremely slow, when I look at the query it is "copying to tmp table". These tables are very large especially search_attribute (79 million rows) and search_attribute_values (350,000 rows)
SELECT attributenames.name, search_attribute_values.value
FROM attributenames, categorysearchattributes, search_attribute, search_attribute_values
WHERE
categorysearchattributes.attributeid = attributenames.attributeid AND categorysearchattributes.categoryid = 4800 AND
categorysearchattributes.attributeid = search_attribute.attributeid AND
search_attribute.valueid = search_attribute_values.valueid AND
attributenames.localeid = 1
GROUP BY search_attribute.valueid
Here is a picture of the EXPLAIN of the query

Added attributeid_valueid index
By looking at the EXPLAIN query in the picture, the table search_attribute is doing a full table scan i.e. not using indexes at all.
Adding index to valueid column of search_attribute table should make it faster. Give it a try and share your results after adding index.
ALTER TABLE `search_attribute` ADD KEY `idx_valueid` (`valueid`);
Please try the combinations of suggestions below.
i am following this tutorial to make oauth server with mongodb, and with mongodb it works fine.
But then i try to change to sails-mysql, but i am having some problems, for example if i change the connection to mysql, if i try to create new client/user it works... but then, if i want to verifi the link, it returns this error:

Thanks.
I am making a simple MySQL database but i keep getting an error:Cannot add foreign key constraint any help appreciated!
Also a Side question is there any difference between using symbol ` and ' while creating your database?
/*!40101 SET NAMES utf8 */;

CREATE DATABASE /*!32312 IF NOT EXISTS*/`a3823833_MiniPost` /*!40100 DEFAULT CHARACTER SET latin1 */;

/*Table structure for table `user` */
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (

the bigint(10) and int(11) are not the same. make em same, and pk on parent table (as u are)
