When encountering the error 1179: Transaction is read-only in MySQL, follow these steps:
SHOW VARIABLES LIKE 'transactionreadonly';
If the value is `ON`, your transaction is set to read-only. To change it for the current session, execute:SET SESSION transactionreadonly = OFF;
SELECT @@GLOBAL.txisolation, @@txisolation;
If necessary, adjust the isolation level for your session. For example, to set it to READ-COMMITTED, use:SET SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED;
SHOW GRANTS FOR CURRENT_USER;
If write permissions are missing, you might need to contact someone with administrative privileges or, if you have the necessary credentials, grant the permissions yourself (ensure you understand the security implications):GRANT INSERT, UPDATE, DELETE ON yourdatabasename.* TO 'yourusername'@'yourhost';
Replace `yourdatabasename`, `yourusername`, and `yourhost` with the actual database name, your MySQL username, and host, respectively.
SHOW GLOBAL VARIABLES LIKE 'read_only';
If it’s set to `ON` and you have the necessary privileges, you can turn it off with:SET GLOBAL read_only = OFF;
Be cautious with this step as it affects the entire database server.
SHOW VARIABLES LIKE 'log_error';
Then, check the contents of the log file for relevant messages.
Proceed with caution and ensure you understand the implications of each action, especially when modifying global variables or granting permissions.
