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

Not sure about the table already existing, but the reason it's not letting you choose the column you want is most likely due to the columns not being the same type. Check to ensure they are both the same type, same length, and have all the same options.
