Hi,
here you mentioned, you wanted to filter only Jan 2000 data
Start date From 1/1/2000 to 1/31/2000
OR
End date from 1/1/2000 to 1/31/2000
but in here, you mentioned both JAN , FEB and null values
If a record has startdate as 1/21/2000and end date as 2/27/2000 or Null I want it to be captured
can you explain what is your requirement ?
