SQL view with If...Then...Else for Column

Lets say I have the following table:
OriginalDate   NewDate  GoodData Value
1/1/2008        2/2/2008    1                109
1/2/2008        3/3/2008    0                401

I want to create a view with 2 columns: Date, Value
If GoodData = 1, I want Date to show OriginalDate
if GoodData =0, I want Date to show NewDate

so SELECT * FROM View1 would return
Date         Value1
1/1/2008   109
3/3/2009   401
Watch Question

create view View1 as
select case gooddata when 1 then originaldate when 2 then NewDate else null end, value
from YourTable

Not the solution you were looking for? Getting a personalized solution is easy.

Ask the Experts
CREATE VIEW View1(Date, Value1) AS
SELECT CASE GoodData WHEN 1 then OriginalDate WHEN 0 THEN NewDate ELSE null END, VALUE
FROM YourTable;
The ELSE null part is not really required for your exact requirement.
