Migrating a self referencing table using Azure Data Factory

Question

I am trying to migrate a table which has 2 colums.

Id - Primarky key
Parent ID - Foreign key populated by the value above (Id). 

(So basically the FK is in the same table) When I migrate this, I get the following error. "The UPDATE statement conflicted with the FOREIGN KEY SAME TABLE constraint" Please let me know how to deal with this. Thanks in advance

Answer 1

Disable the foreign key constraint first. Then migrate your data. And afterwards you can enable the constraint again.

ALTER TABLE Purchasing.PurchaseOrderHeader  
NOCHECK CONSTRAINT FK_PurchaseOrderHeader_Employee_EmployeeID; 


ALTER TABLE Purchasing.PurchaseOrderHeader  
CHECK CONSTRAINT FK_PurchaseOrderHeader_Employee_EmployeeID;  

Disable foreign key constraints with INSERT and UPDATE statements
