MySQL 1734

This error occurs when a subpartition is used instead of a partition in a MySQL statement. It is a reminder to use the correct syntax when creating partitions.

How It Affects Your App

The error 1734 ER_PARTITION_INSTEAD_OF_SUBPARTITION indicates that the application is attempting to use a partition instead of a subpartition. This can cause the application to fail, as the partition and subpartition have different functions and cannot be used interchangeably. As a result, the application may not be able to access the data it needs, or may not be able to store data in the correct format. This can lead to data loss or corruption, and can cause the application to crash or malfunction.

How To Fix

1. Check the error log for the MySQL 1734 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:
$ cat /etc/mysql/my.cnf
3. Check the MySQL process list for any suspicious activity:
$ mysqladmin -u root -p processlist
4. Check the MySQL user table for any suspicious users:
$ mysql -u root -p -e "SELECT * FROM mysql.user;"
5. Check the MySQL grant tables for any suspicious grants:
$ mysql -u root -p -e "SELECT * FROM mysql.db;"
6. Check the MySQL system variables for any misconfigurations:
$ mysql -u root -p -e "SHOW VARIABLES;"
7. Check the MySQL system status for any misconfigurations:
$ mysql -u root -p -e "SHOW STATUS;"
