  Hi,

  I have the following data in a table :

  EmpNo BudgetYearStartBudgetYearEnd

  2698 2013-02-012014-01-31

  67682 2013-01-012013-12-31

  43320 2013-02-012014-01-31

  2849 2013-03-012014-02-28

  67687 2013-01-012013-12-31

  67675 2013-01-012013-12-31

  67678 2013-01-012013-12-31

  54870 2013-02-012014-01-31

  2564 2013-01-012013-12-31

  41777 2013-01-012013-12-31

  52890 2013-01-012013-12-31

  669 2013-01-012013-12-31

  54517 2013-02-012014-01-31

  68929 2012-12-282012-12-31----

  68929 2013-01-012013-12-31----

  68134 2013-01-012013-12-31

  67671 2013-01-012013-12-31

  54171 2013-01-012013-12-31

  52959 2013-01-012013-12-31

  41771 2013-01-012013-12-31

  676 2013-01-012013-12-31

  41628 2013-01-012013-12-31

  12387 2013-01-01 2013-12-31

  Now I need to get all the Emp Nos who have active current budget and also who have a previous budget for them which ended just one day prior to the current budget start date which means the difference between the current budget year start and the previoud budget year end should be 1.

  Example

  68929 2012-12-282012-12-31----

  68929 2013-01-012013-12-31---

  12387 2013-01-01 2013-12-31

  this person 68929 has a current budget which is still active till dec 31 2013 and also has a previous budget which ended on dec 31 2012.

  The person 12387 does not have a previous budget year end and has only current budget start and end.

  Now i should get only the emp no row with current budget and who has previous budget year end.

  Result should be only

  68929 2013-01-012013-12-31

  Thank You All in advance

  SELECT '12387','2013-01-01','2013-12-31'

  )

  SELECT * FROM MyCTE

  where getdate() between [BudgetYearStart] AND [BudgetYearEnd];
