Script to create user

This MySQL script can be used to create a user with the necessary permissions inside of your database. You will need appropriate database permissions to run the script. The username will be migration_user. Make sure to update the following variables:

<SUPER_STRONG_PASSWORD> — The password for the migration_user account.
<DATABASE_NAME> — The name of the database you will import into PlanetScale.

CREATE USER 'migration_user'@'%' IDENTIFIED BY '<SUPER_STRONG_PASSWORD>';
GRANT PROCESS, REPLICATION SLAVE, REPLICATION CLIENT, RELOAD ON *.* TO 'migration_user'@'%';
GRANT SELECT, INSERT, UPDATE, DELETE, SHOW VIEW, LOCK TABLES ON `<DATABASE_NAME>`.* TO 'migration_user'@'%';
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER ON `ps\_import\_%`.* TO 'migration_user'@'%';
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER ON `_vt`.* TO 'migration_user'@'%';
GRANT EXECUTE ON PROCEDURE mysql.rds_show_configuration TO 'migration_user'@'%';
GRANT SELECT ON mysql.db TO 'migration_user'@'%';
GRANT SELECT ON mysql.func TO 'migration_user'@'%';
GRANT SELECT ON mysql.innodb_table_stats TO 'migration_user'@'%';
GRANT SELECT ON mysql.tables_priv TO 'migration_user'@'%';
