Question

I have exchange rate table in which there are multiple date wise records with exchange rate.

Date           Rate
17/05/2012     5
23/05/2012     6
27/05/2012     7

Now I want rate while passing any date like if, I pass 20/05/2012 then rate 5 should return because 20/05/2012 elapse in date range 17 and 23 may 2012.

Answer 1

Assuming you have correct datatypes (that is, not varchar to store date values…)

SELECT TOP 1
  Rate
FROM
  MyTable
WHERE
  DateColumn <= '20120520'
ORDER BY
  DateColumn DESC
