The ALTER TABLE statement conflicted

Question

alter FUNCTION [Kuri].[fnGetAge](@kuri_cust_Id int,@amt decimal)
RETURNS SMALLINT
AS
    BEGIN
    DECLARE @isVallid  bit = 0
    declare @payed decimal(14,2)
    de         


        

Answer 1

As the error clearly states: there are rows in your table that violate your check constraint.

Since your check constraint tests for kuri.fnGetAge(kuri_Cust_ID,amt) >= 1, you can find those rows in violation of this check constraint using

  SELECT * FROM Kuri.Payment
  WHERE kuri.fnGetAge(kuri_Cust_ID, amt) < 1

Fix or delete those rows, and then you should be fine and your ALTER TABLE command should work
