Unable to create or change a table without a primary key - Laravel DigitalOcean Managed Database

Question

I've just deployed my app to DigitalOcean using (Managed Database) and I'm getting the following error when calling php artisan migrate

SQLSTATE[HY000]: General error: 3750 Unable to create or change a 
table without a primary key, when the system variable 'sql_require_primary_key'
is set. Add a primary key to the table or unset this variable to avoid
this message. Note that tables without a primary key can cause performance
problems in row-based replication, so please consult your DBA before changing
this setting. (SQL: create table `sessions` (`id` varchar(255) not null,
`user_id` bigint unsigned null, `ip_address` varchar(45) null,
`user_agent` text null, `payload` text not null, `last_activity` int not null)
default character set utf8mb4 collate 'utf8mb4_unicode_ci')

It appears that Laravel Migrations doesn't work when mysql var sql_require_primary_key is set to true.

Do you have any solutions for that?

Answer 1

According to the MySQL documentation purpose of this system variable is

to avoid replication performance issues: "Enabling this variable helps avoid performance problems in row-based replication that can occur when tables have no primary key."

IMHO, there are two possible options to consider for your problem;

• Add primary key to this and every table in your migration, including temporary tables. This one is better and i think more convenient way to do it since there is no drawback to have primary key for each table.

Whether statements that create new tables or alter the structure of existing tables enforce the requirement that tables have a primary key.

• Change your provider because according to here "We support only MySQL v8."
