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.. :)
