Hi,

I have the following constraint set on the foreign key field of the child table:
ALTER TABLE [dbo].[child_tbl]  WITH CHECK ADD  CONSTRAINT [FK_child_tbl_employee] FOREIGN KEY([employee])
REFERENCES [dbo].[parent_tbl] ([employee])
Why do you think the following code in the SSMS gets error of constraint conflict?
use [MyDatabase]
go 
begin transaction
update parent_tbl set employee = 'TEST34' where employee = 'TEST1'
go
update child_tbl set employee = 'TEST34' where employee = 'TEST1'
go
commit 
TIA
