I am sorry, but could you please post in English? Also, please include the INSERT_DATA string. Thanks.

Вместо слова " посетителей." в таблицу записывается " поÑ�етителей."
В мониторинге порта Serial.println(query); выводится слово " посетителей.", а до таблицы доходят каракули.

Hello.
void loop() { Instead of the word " посетителей.", the table is written " Ð¿Ð¾Ñ ÐµÑ‚Ð¸Ñ‚ÐµÐ»ÐµÐ¹." |

Hi. I have not tried the Russian language, but if MySQL is configured to support it and the chars are 1-byte each, it should work, but I know it does not support 2-byte chars.

Hello.
Please tell me, does MySQL_Connection support sending queries with words in Russian?
char table_name[] = "org_events";
char shop_name[] = "Maximum"; //Пока только на английском языке.
char INSERT_DATA[] = "INSERT INTO %s.%s (event_caption, event_type, start_date, finish_date, label_color, event_message, event_options, recurrence_idx, reminder_date, reminder_min_before_start, resource_id, event_state, doc_id, project_id) VALUES ('%s', 0, CURDATE(), DATE_ADD(CURDATE(), INTERVAL 1 DAY), '536870912', '%s', 3, -1, NOW(), 15, 0, 0, 0, 1)";

delay(60000);
}
Instead of the word " visitors.", the table is written " Ð¿Ð¾Ñ ÐµÑ‚Ð¸Ñ‚ÐµÐ»ÐµÐ¹."
In port monitoring Serial.println(query); the word " visitors" is displayed.", and doodles reach the table.

Russian Russian letters are freely supported by MySQL, and in Serial.println(query); text with Russian letters is displayed, which is sent to the table, and incorrectly interpreted characters are written to the table. Is there any plans to support Russian letters? |

Hi. Not immediately, now, but let’s leave this request open and I’ll look into it. Or you can if you’d like. :)

I'm not good at programming. Everything I can do is thanks to ChatGPT, but all the advice he gives me on fixing my code doesn't work. |

Do you know which collation you are using in MySQL? If you can identify a charset/collation, I may be able to suggest a quick hack to make it work. Is it one of these? If so, which one?

Basically, open MySQL_Packet.cpp and change line#122 to set the charset number from 08 to whatever you want. For example, the following are the Cyrillic charsets that MySQL supports.
mysql> SELECT id, collation_name FROM information_schema.collations WHERE collation_name like '%1251%' ORDER BY id;
+----+---------------------+
| id | collation_name |
+----+---------------------+
| 14 | cp1251_bulgarian_ci |
| 23 | cp1251_ukrainian_ci |
| 50 | cp1251_bin |
| 51 | cp1251_general_ci |
| 52 | cp1251_general_cs |
+----+---------------------+
5 rows in set (0.00 sec)
For example, suppose your desired charset if cp1251_general_ci, which is id = 51. We convert it to hex (0x33) and change:
// charset - default is 8
buffer[size_send] = byte(0x08);
To:
// charset - default is 8
buffer[size_send] = byte(0x33); // cp1251_general_ci
This should work and worth a try. If you get a chance to try it, let me know if it works. If it does, I will put it on the list for the next revision.

I can't change anything in the MySQL database, because a trade accounting program works with its tables. If I change MySQL parameters, then my program stops working correctly. I am assembling an Arduino device that sends some data to the MySQL database tables of the program. I adjust my device to the DB, not the DB to my device. |

You need not change the DB. The suggested code changes the connector on
your Arduino to match the character set on the DB.

I'm sorry, I didn't understand you. I'm not a programmer and I don't understand many terms. I need time to understand what you wrote to me. I will study all your answers and come back with the results. |
|
I'm sitting now, trying to understand your answer and change the sketch code. |
|
That's it, got it. I'll check it out now. |
|
buffer[size_send] = byte(0x33); it didn't work. Signed up for the table - Maximum: 16 посетителей. |
|
The connector can be altered to support Russian. Here’s how you do it. It’s a multi-step process.
First, modify MySQL_Packet.cpp as suggested only use 0x24 (for charset cp866).
buffer[size_send] = byte(0x24);
Next, create (or alter) your table to use that character set and default collation for the column(s) you want to support.
CREATE TABLE test.lang (a int auto_increment primary key, b char(40) charset cp866 collate cp866_general_ci);
Next, change the charset in the MySQL monitor (mysql) to use the new charset.
mysql> \C cp866
Charset changed
Finally, execute your script. I wrote a simple INSERT to use the phrase, “правильная фраза”.
Observe:
mysql> select * from test.lang;
+---+---------------------------------+
| a | b |
+---+---------------------------------+
| 1 | правильная фраза |
+---+---------------------------------+
1 row in set (0.00 sec)
Done. :)

Здравствуйте.
Подскажите пожалуйста, MySQL_Connection поддерживает отправку запросов со словами на русском языке?
void loop() {
int value = random(101);
String event_caption = String(shop_name) + ": " + String(value) + " посетителей.";
String event_message = String(shop_name) + ": " + String(value) + " посетителей.";
MySQL_Cursor *cur_mem = new MySQL_Cursor(&conn);
char query[512];
sprintf(query, INSERT_DATA, db_name, table_name, event_caption.c_str(), event_message.c_str());
Serial.println(query);
cur_mem->execute(query);
delete cur_mem;
delay(60000);
}
Вместо слова " посетителей." в таблицу записывается " поÑ�етителей."
В мониторинге порта Serial.println(query); выводится слово " посетителей.", а до таблицы доходят каракули.
The text was updated successfully, but these errors were encountered:
