How It Affects Your App
The error indicates that the field length of a column is too large for the data type. This can cause data to be truncated or lost, resulting in incorrect or incomplete data being stored in the database. This can lead to incorrect results when querying the database, or even data corruption. It can also cause the application to crash or malfunction, leading to a poor user experience.
How To Fix
1. Identify the source of the MySQL 1074 error. This can be done by checking the error log for the MySQL server.
$ tail -f /var/log/mysql/error.log
2020-08-20T14:45:00.123456Z 0 [ERROR] [MY-01074] [Server] Command Out of Sync. You can't run this command now
2. Check the syntax of the query that caused the error.
$ mysql -u root -p
mysql> SELECT * FROM users WHERE id = 1;
3. Check the version of MySQL server.
$ mysql -V
mysql Ver 8.0.20 for Linux on x86_64 (MySQL Community Server - GPL)
4. Check the MySQL server configuration.
$ cat /etc/my.cnf
[mysqld]
max_allowed_packet=16M
5. Increase the max_allowed_packet size in the MySQL server configuration.
$ sudo vi /etc/my.cnf
[mysqld]
max_allowed_packet=32M
6. Restart the MySQL server.
$ sudo service mysql restart
7. Re-run the query that caused the MySQL 1074 error.
$ mysql -u root -p
mysql> SELECT * FROM users WHERE id = 1;
8. As a final step, it is recommended to use an automated database observability tool to monitor and fix the MySQL 1074 in question. Automated database observability tools can provide real-time insights into the performance and health of the database, allowing for quick identification and resolution of any issues. Additionally, these tools can provide detailed metrics and logs that can be used to troubleshoot and debug any issues that may arise.
