ERROR 3750 (HY000) at line 31: 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.

Hi @SleepingDarkBlueScubaDiver,
I can see you are using DigitalOcean Managed MySQL Database. This requires you to have primary keys set on each table. What I’ll recommend is to add primary keys to your tables and then try again to import it.
