first do you first update, then:
update whattable set price = 5 where price IS NULL
From now onwards, all goods without price before will now cost 5 yourPriceUnit. Is this really correct?
krs,

Yes...keep in mind you can't do arithmitic operations with null values.
Write the following query:
update Tablename set columnName = coalesce(columnname,0) + AdditionValue
You will get desired result.. :)
