Adding foreign key to existing table gives error 1050 table already exists

Question

I\'ve a table CustomizationSet with the columns:

customization_set_guid (which is a non-nullable guid and also the primary key)
creator_account_guid
and a fe         


        

Answer 1

• Check the Storage Engine type for CustomizationSet table.

I had a same issue but i could solve it by changing engine type to InnoDB , because few types don't support foreign key constraints.
