i have the data if AFG is Yes or Type is N/A then we need to count as 1 valid record
Condition 1
AFG       Type
yes          N/A
COnditon 2 - If AGF is No or Type is Phys then we need to count as another valid record
AFG   Type
No       Phys

Also for these both conditions we have to check the record is active or not, for that we need to check start date should be less than current date and end date should be future data.. if it is valid then only we can check both the oncditons

You should know the deal by now. For any help we need DDL, sample data and expected results. I'd also like to know what have you tried as a simple CASE expression should do the trick.

Adding to what Luis said I think you need to use count and case expression along with group by function

Something like this:
SELECT
[RowIsValid] = CASE
  WHEN AFG = 'Yes' OR [Type] = 'N/A' THEN 1
  WHEN AGF = 'No' OR [Type] = 'Phys' THEN 2
  END,
[RowIsActive] = CASE WHEN [start date] < GETDATE() AND [end date] > GETDATE() THEN 1 ELSE 0 END

As others have stated, much easier to do when sample data is provided.
