How It Affects Your App
MySQL 1786 ER_GTID_UNSAFE_CREATE_SELECT error indicates that the application is trying to execute a CREATE SELECT statement that is not safe for GTID-based replication. This can lead to data inconsistency and data loss in the application. It can also cause replication to fail, resulting in the application not being able to access the data it needs. This can lead to application downtime and data loss.
How To Fix
1. Check the syntax of the query:SELECT * FROM table_name WHERE column_name = 'value';
2. Check the data type of the column:SHOW COLUMNS FROM table_name WHERE Field = 'column_name';
3. Check the value of the column:SELECT column_name FROM table_name WHERE column_name = 'value';
4. Check the collation of the column:SHOW FULL COLUMNS FROM table_name WHERE Field = 'column_name';
5. Change the collation of the column to match the value:ALTER TABLE table_name MODIFY column_name VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_general_ci;
6. Check the query again:SELECT * FROM table_name WHERE column_name = 'value';
7. Use an automated database observability tool to monitor and fix the MySQL 1786 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.
