如何解决我的数据库迁移中的排序规则错误？

Question

I am trying to migrate my db from localhost onto cleardb. Upon importing my db onto cleardb I am getting the error Unknown collation: 'utf8mb4_0900_ai_ci'. I have no idea what a collation is, nor can I find anything online about what collation's cleardb accepts. I'm guessing it has something to do with the character set that is being submitted.

What are my option on how to fix this?

thanks

Answer 1

for collation error, you need to follow the following steps

1, go to config/database.php file
2, set charset="utf8" and collation="utf8_general_ci"

final MySQL array show like below

'mysql' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_general_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => 'InnoDB',
            'options' => extension_loaded('pdo_mysql') ? array_filter([
                PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
            ]) : [],
        ],
