I have an SQL statement that has a CASE
from SELECT
and I just can't get it right. Can you guys show me an example of CASE
where the cases are the conditions and the results are from the cases. For example:
Select xxx, yyy
case : desc case when bbb then 'blackberry';
when sss then 'samsung';
end
from (select ???? .....
where the results show
name age handphone
xxx1 yyy1 blackberry
xxx2 yyy2 blackberry
The MSDN is a good reference for these type of questions regarding syntax and usage. This is from the Transact SQL Reference - CASE page.

USE AdventureWorks2012;
GO
SELECT ProductNumber, Name, "Price Range" =
CASE
WHEN ListPrice = 0 THEN 'Mfg item - not for resale'
WHEN ListPrice < 50 THEN 'Under $50'
WHEN ListPrice >= 50 and ListPrice < 250 THEN 'Under $250'
WHEN ListPrice >= 250 and ListPrice < 1000 THEN 'Under $1000'
ELSE 'Over $1000'
END
FROM Production.Product
ORDER BY ProductNumber ;
GO
Another good site you may want to check out if you're using SQL Server is SQL Server Central. This has a large variety of resources available for whatever area of SQL Server you would like to learn.
