How It Affects Your App
MySQL 1175 ER_UPDATE_WITHOUT_KEY_IN_SAFE_MODE prevents an application from updating a table without a key in safe mode. This means that the application must use a key to identify the row to be updated, which can be time consuming and difficult to implement. Without a key, the application may not be able to update the table correctly, leading to data integrity issues. This can cause the application to malfunction or crash, resulting in a poor user experience.
How To Fix
1. Identify the cause of the MySQL 1175 error:
SELECT * FROM table_name;
ERROR 1175 (HY000): You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column
2. To fix the error, the user must disable safe update mode:
SET SQL_SAFE_UPDATES = 0;
3. After disabling safe update mode, the user can now update the table without a WHERE clause:
UPDATE table_name SET column_name = value;
4. Re-enable safe update mode:
SET SQL_SAFE_UPDATES = 1;
5. As a best practice, use an automated database observability tool to monitor and fix MySQL 1175 errors. Automated database observability tools can detect MySQL 1175 errors and alert the user when they occur. They can also provide detailed information about the cause of the error and suggest possible solutions. This can help the user quickly identify and fix the issue, and prevent similar errors from occurring in the future.
