Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

Adding NULL value

Feb 2, 2010 8:10AM edited Mar 20, 2010 11:22PM in SQL Language (MOSC) 6 commentsAnswered

I have a table like where column B does not have any data entered yet

A B

1

21

When I write "Select" Statement like

Select A, B, A+B

The column "A+B" does not return anything. How can I get the sum equal to A if B is Null? Please help.
