The DELETE statement conflicted

Question

Hi,

 

I write a simple delete query. And execute that query. Then I found below error.

Msg 547, Level 16, State 0, Line 5
The DELETE statement conflicted with the REFERENCE constraint "FK_tb_state_tb_country". The conflict occurred in database "EmployeeDB", table "dbo.tb_state", column 'country_id'.
The statement has been terminated.

Is there any solution for above??
