Sql ошибка 1193

Ok so i’m working on triggers, and it tells me it(MySQL workbench 5.2) doesn’t recognize this variable.
*Error Code: 1193. Unknown system variable error_msg_3*

I think it would be correct using it in a trigger, please help me

CREATE TRIGGER controlla_MaxCARDINALITA_INSERT
BEFORE INSERT ON SENTIERO__HA__TAPPA
FOR EACH ROW 
BEGIN

DECLARE max_cardinalita INTEGER;
DECLARE error_msg_3 CONDITION FOR SQLSTATE '99003';

SELECT COUNT(*) into max_cardinalita
FROM SENTIERO__HA__TAPPA
WHERE IDsentiero=NEW.IDsentiero;

IF max_cardinalita>=10 THEN
        SIGNAL error_msg_3;
        SET error_msg_3='INSERT: Il sentiero ha già il massimo numero di tappe consentito';

END IF;

END$$

EDIT ::

I tried this, and it seems working

DECLARE msg VARCHAR(255);
set msg = concat('MyTriggerError: Trying to insert a negative value in trigger_test: ');
signal sqlstate '45000' set message_text = msg;

The MySQL database that I have connected to in the past has been updated to version 5.6.20.

Now, when I try to connect with MySQL-CC I get the following error reported:

Error 1193: Unknown system variable 'SQL_MAX_JOIN_SIZE'

Has this variable gone missing in the update?

Or was it missed out by the person doing the update here?

What should I do to fix this?

The list of changes in MySQL 5.6 is at

http://dev.mysql.com/doc/refman/5.6/en/mysql-nutshell.html

Under Removed Features it says:

The sql_max_join_size system variable. Use max_join_size instead.

A number of other system variables have been removed and replaced with new variables. I’ll bet they were deprecated in previous releases, but I haven’t checked.

I had a batch file to invoke mysql with -U, and removing -U solved this problem.

According to MySQL docs, the error #1193 occurs when you use wrong code for SQLSTATE.

Message: Unknown system variable %s

And, as you can see on the same page, the SQLSTATE 99003 is not defined.

```
please see my edit, why does that code work? there isn’t 45000 in the table, i think
@Jimmy5nomana Please again, refer to the docs on usage of SIGNAL clause. It clearly mentions: SIGNAL is the way to “return” an error. SIGNAL provides error information to a handler, to an outer portion of the application, or to the client. To signal a generic SQLSTATE value, use ‘45000’, which means unhandled user-defined exception.
Thanks, last question for you: mysql doesn’t let me using multiple triggers for the same event and action time for one table… so i heared about functions and procedures; are them the solution? I’d like to solve it in the easiest way, i’m in hurry. Thanks
@Jimmy5nomana For that, you’d get better advices over at DBA stackexchange
That’s not theory!!! if you have 3 triggers as these: AFTER UPDATE ON TABLE 1… how could they run on that table?

When restoring MySQL backup taken on Amazon RDS, i get error

root@PRD—50ml:~# mysql sok_db2 < db.sql

ERROR 1193 (HY000) at line 24: Unknown system variable ‘GTID_PURGED’

root@PRD—50ml:~#

To fix this, open db.sql in text editor, remove the line

SET @@GLOBAL.GTID_PURGED=»;

Another solution is take a new MySQL backup with –set-gtid-purged=OFF option and restore it.

mysqldump —u DB_USER —p —set—gtid—purged=OFF —triggers —routines —events DB_NAME > DB_NAME.sql

Я недавно установил MySQL и phpMyAdmin, но когда я пытаюсь войти в phpMyAdmin с правами суперпользователя, я получаю следующую ошибку для этого запроса:

SQL-запрос:

SET lc_messages = 'en_US';

MySQL сказал: Документация

# 1193 — Неизвестная системная переменная ‘lc_messages’

Почему я испытываю эту ошибку?

Решение

Я столкнулся с той же проблемой. Проверьте свою версию MySQL:

Для mySQL 5.5 используйте phpMyAdmin 4.4.x и выше

Для mySQL 5.1 используйте phpMyAdmin 4.0.x

Надеюсь, это кому-нибудь поможет.

Это не правда PhpMyAdmin может работать со взрослыми Mysql как всегда.

Быстрая починка это просто

в /usr/share/phpMyAdmin/libraries/common.inc.php удалить эти строки

if (PMA_MYSQL_INT_VERSION < $cfg['MysqlMinVersion']['internal']) {
PMA_fatalError(
__('You should upgrade to %s %s or later.'),
array('MySQL', $cfg['MysqlMinVersion']['human'])
);
}

или же

в /usr/share/phpMyAdmin/libraries/classes/DatabaseInterface.php удалить эти строки

if (! empty($locale)) {
$this->query("SET lc_messages = '" . $locale . "';", $link, self::QUERY_STORE);
}

Ссылка https://github.com/phpmyadmin/phpmyadmin/issues/12822

Удалите свою версию mysql и все зависимости.
Чтобы увидеть все ваши установленные пакеты mysql и зависимостей, попробуйте эту команду:

- rpm -qa | grep mysql

Для удаления:

- yum erase mysql
- yum erase mysqlPackageDependencie
...

Когда все зависимости будут удалены, установите новую версию mysql:

- yum install mysql55-server

Запустите ваш сервис Mysql:

- service mysqld start

Большой! Все работает отлично сейчас! 🙂

Я обнаружил, что у меня была более старая версия phpmyadmin, и ошибка была из-за изменения, которое они внесли в PHP 7.

Если вы используете любую версию php 5.5 или выше, вы получите эту ошибку, если вы не обновите свой phpmyadmin.
