How to write a cursor inside a stored procedure in SQL Server 2008

Question

I have two tables in my database

Coupon Table

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

Coup

Answer 1

What's wrong with just simply using a single, simple UPDATE statement??

UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)

That's all that's needed ! No messy and complicated cursor, no looping, no RBAR (row-by-agonizing-row) processing ..... just a nice, simple, clean set-based SQL statement.
