I Have An existing database with me which is working well in my Earlier Service Provider in connection with my Infra Update and i tried to restore the database in to the MySQL Managed Databases option provided by DO. while restoring the DB am getting an error like this

"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.

Operation failed with exitcode 1 "

HOW CAN I RESTORE THE DB WITHOUT SETTING THE primary_key FOR ALL MY TABLES .

Hi, It seems to be a requirement now, when you use DO Managed MySQL Database. I mean, to have a primary key in every database table. You can find out more under Known Issues paragraph in DO product documentation: https://www.digitalocean.com/docs/databases/mysql/
