See more:

select A.Visibility,A.MsgDatetime,I.Stationname,I.ICAOCode from AVI_02Mar2016 A join AVI_ICAOCodeList I on A.ICAOCode =I.ICAOCode where I.country ='India' and
MsgDatetime between convert(datetime,'02 Mar 2016 11:00:00') and convert(datetime,'02 Mar 2016 12:00:00')

What I have tried:

SELECT MAX(Visibility) FROM AVI_02Mar2016
WHERE Visibility IN (select A.Visibility,A.MsgDatetime,I.Stationname,I.ICAOCode from AVI_02Mar2016 A join AVI_ICAOCodeList I on A.ICAOCode =I.ICAOCode where I.country ='India' and
MsgDatetime between convert(datetime,'02 Mar 2016 11:00:00') and convert(datetime,'02 Mar 2016 12:00:00'))

And?
What happened that you didn't expect, or didn't happen that you did?

That tells us nothing - we can infer that from your question - but we have no access to your data, so we do not know what you do get, and from what input. Since both of those are likely to be relevant to the question, we need better information in order to help you!
So...try posting "sample data" which shows the problem, and show us what you get from it, and what you expect to get. We can't work in the dark! :laugh:
