• Name (nvarchar(max))
• NoofUses (int)

Coup

Answer 1

You can create a trigger which updates NoofUses column in Coupon table whenever couponid is used in CouponUse table

query :

CREATE TRIGGER [dbo].[couponcount] ON [dbo].[couponuse]
FOR INSERT
AS
if EXISTS (SELECT 1 FROM Inserted)
  BEGIN
UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)
end
