Posted on 2014-08-19

Good Day,

I need to  write a  SQL query that goes something  like this:

Select  [apples], [oranges], {bananas],  [price] from Fruit_Tabletable where
if [price]  >0, then [apples] =Yes and oranges= Yes

I need to only show apples and oranges  where the cost is  grater than zero and have "Yes" appear in the apples and oranges fields .

Thanks,

I need to only show apples and oranges  where the cost is  grater than zero and have "Yes" appear in the apples and oranges fields .
``````SELECT  apples ,
oranges ,
bananas ,
price
FROM    Fruit_Tabletable
WHERE   price > 0
AND apples = 'Yes'
AND oranges = 'Yes';
``````
But columns named like fruits makes no sense in a normal model. E.g. a better model

``````DECLARE @Fruits TABLE
(
FruitID INT ,
FruitName NVARCHAR(255)
);

INSERT  INTO @Fruits
VALUES  ( 1, 'Apple' ),
( 2, 'Orange' ),
( 3, 'Banana' );

DECLARE @Prices TABLE
(
FruitID INT ,
PriceAmount MONEY
);

INSERT  INTO @Prices
VALUES  ( 1, -1 ),
( 1, 0 ),
( 1, 1 ),
( 2, -2 ),
( 2, 0 ),
( 2, 2 ),
( 3, -3 ),
( 3, 0 ),
( 3, 3 );

SELECT  F.FruitName ,
P.PriceAmount
FROM    @Prices P
INNER JOIN @Fruits F ON F.FruitID = P.FruitID
WHERE   P.PriceAmount > 0
AND F.FruitName IN ( 'Apple', 'Orange' );
``````

results in
``````FruitName	PriceAmount
---------	---------------------
Apple		1,00
Orange		2,00
``````

Not 100% sure what you are asking here:

Select  [apples], [oranges], {bananas],  [price] from Fruit_Tabletable where
if [price]  >0, then [apples] =Yes and oranges= Yes

With the "then [apples] = Yes and Oranges=Yes  piece;

1. Are you wanting to 'set' these as yes? Or
2. Make sure that "IF" the price is greater than 0 there 'has' to be a YES as well???

You will need a 'case' statement in your select
SELECT  apples ,
oranges ,
bananas ,
CASE Fruit
When 'apples' THEN 'YES'
When 'oranges' THEN 'YES'
END AS Fruit_Type,
price
FROM    Fruit_Tabletable
WHERE   price > 0
AND apples = 'Yes'
AND oranges = 'Yes'

if #2 answer is yes; then
you just need a select where you 'WHERE' clauses are
WHERE Price > 0
AND apple = 'Yes'
AND oranges = 'yes'

"OR"
WHERE Price > 0
AND (apple = 'Yes' OR oranges = 'yes' )

Hope this helps

Thank you for your quick response, Spt_Us . " Are you wanting to 'set' these as yes? " is the scenario that I was aiming for and your solution works perfectly.
