Question

I have SQL table in SQL server 2008, and I want to get latest record which depends on its date.

I have written a query as

  SELECT TOP 1 * 
    FROM ProductPrice
   WHERE ProductID = 1698
     AND EffectiveFrom <= '1/31/2013'
ORDER BY EffectiveFrom DESC

and in the database there is a record which contains the Date 2013-01-31 12:12:49.000

Now I am expecting above query will return 1 record, but its not returning anything
What should I change in the query ?

Answer 1

Because data in table contains not only date, but also time

  SELECT TOP 1 * 
    FROM ProductPrice
   WHERE ProductID = 1698
     AND CAST(EffectiveFrom AS date) <= '1/31/2013'
ORDER BY EffectiveFrom DESC

OR

  SELECT TOP 1 * 
    FROM ProductPrice
   WHERE ProductID = 1698
     AND EffectiveFrom <= DATEADD(SECOND, 86399, '1/31/2013')
ORDER BY EffectiveFrom DESC
