Unable to parse MySQL ALTER statement with named primary key

    XMLWordPrintable

Details

    • Hide

      Create a table:

      CREATE TABLE IF NOT EXISTS tasks_gon (
    task_id INT,
    title VARCHAR(255) NOT NULL
);

      That statement succeeds in MySQL and Debezium is able to process it.

      Add primary key using backquote:

      alter table `tasks_gon`
    add primary key `tasks_gon_task_id_primary`(`task_id`);

      That statement succeeds in MySQL but Debezium fails to parse.

      That kind of statements are generated by Laravel, a PHP framework for DB access. See https://laravel.com/docs/7.x/migrations#creating-tables

      Thank you!
