How It Affects Your App
MySQL 1365 ER_DIVISION_BY_ZERO occurs when a division by zero is attempted in a SQL statement. This can cause the application to crash or freeze, resulting in data loss or corruption. It can also lead to unexpected results in the application, such as incorrect calculations or incorrect data being displayed. This can lead to incorrect decisions being made based on the data, which can have serious consequences.
How To Fix
1. Check the error log for the MySQL 1365 error:
$ tail -f /var/log/mysql/error.log
2. Check the syntax of the query causing the error:
$ mysql -u root -p
mysql> SHOW WARNINGS;
3. Check the query for any syntax errors:
mysql> EXPLAIN SELECT * FROM table_name;
4. Check the table structure for any inconsistencies:
mysql> SHOW CREATE TABLE table_name;
5. Check the table indexes for any inconsistencies:
mysql> SHOW INDEX FROM table_name;
6. Check the table data for any inconsistencies:
mysql> SELECT * FROM table_name;
7. Fix any inconsistencies found in the previous steps:
mysql> ALTER TABLE table_name MODIFY COLUMN column_name datatype;
8. Use an automated database observability tool to monitor and fix the MySQL 1365 in question. Automated database observability tools can help identify and diagnose issues quickly, as well as provide insights into the performance of the database. They can also provide alerts when issues arise, allowing for quick resolution.
