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

I had a similar problem and in the end it was a problem of Integrity Constraint. The Foreign Key column was referencing a foreign column that didnt exist.

Try run the following to test whether this is the case:

select r.customization_set_guid, c.customization_set_guid
from Registration r
right join CustomizationSet c
on 
r.customization_set_guid = c.customization_set_guid
where isnull(c.customization_set_guid);
