Question

I have the following query:

DECLARE @IsStocked bit
SELECT * FROM Products p WHERE p.LastSeen >  GETDATE() - 30 

This returns all Products that have been seen within the last 30 days.

My question is, I would like the p.LastSeen > GETDATE() - 30 clause to only apply when @IsStocked = true.

This is part of a larger query, and I’d like to achieve this without using IF/ELSE statements (i.e. if @IsStocked = false the p.LastSeen > GETDATE() - 30 section of the WHERE clause is ignored completely).

Thanks!

Answer 1

DECLARE @IsStocked bit

SELECT * FROM Products p
WHERE  @IsStocked = 0 OR (p.LastSeen > GETDATE() - 30);
