Hi,

I need to know

1. length of City Field.
2. How are you adding city? Means while inserting new country you are adding multiple city at same time or you want to update city flied by adding one more cityin existing cites.

Peter mentioned a very valid point. But, in case you have to do it, here is the way:

UPDATE Region
SET City = 'jakarta, bandung, jogja'
WHERE country = 'Indonesia'

It can but should not be done. Never put multiple values in a single cell. It is against 1NF principle. In relational database design, every cell must not take more than one value, like separated with commas. They should be separated into multiple rows.
