I have some negative values coming back from a query. I would like them to just be zero. How do I write a condition in my sql query that returns zero if the value is below a certain value.
sol:
CASE WHEN CONVERT(float,dt.FQI53X02_101) < 1.3 THEN 0 ELSE CONVERT(float,dt.FQI53X02_101) END AS FQI53X02_101
You dont use If-Then-Else in the actual query (you can use them but thats something else)...
What you use is a Case statement... Try this
Select
Case When [Value] < 0 Then 0 Else [Value] End
From
Example
If you want it as part of your query, wrap the return inside a CASE statement. Example from MSDN is below
SELECT 'Price Category' =
CASE
WHEN price IS NULL THEN 'Not yet priced'
WHEN price < 10 THEN 'Very Reasonable Title'
WHEN price >= 10 and price < 20 THEN 'Coffee Table Title'
ELSE 'Expensive book!'
END,
CAST(title AS varchar(20)) AS 'Shortened Title'
FROM titles
ORDER BY price
( ABS(Value) + Value ) / 2
