I have a requirement like
if payment_type = 's' then compensation is weekly_rate * 4
but if weekly_rate is 0 or null then compensation is 0
if payment_type = 'p' return the value in gross_amount column.

Below is the decode function I have used. Would like to know how to do the same using db2 functions.

Decode(payment_type, �s�, (decode(nvl(weekly_rate,0.00),0.00,0.00, weekly_rate*4)) ,�p�,gross_amount)
