I have table called Tracking_changes which contain 5 columns and 5th column as getdate
I want to get the output ONLY with differences in other column 3 and 4 and getdate with group by
We enter data on daily basis and getdate will capture the data for given date so I need Output for any changes on other column with group by getdate.

I got confused with your explanation. Could you post DDL and sample data (as insert statements) along with expected results based on that sample data?

That will give you better and faster answers.

It's still not clear what you're trying to get at here. What do you mean differences in column 2 and 3? Are you referring to the columns Grade and Sec? It would be clearer if you call them by their names. And what do you mean by difference? Are you trying to compare these rows over time? To eachother? What is the criteria for rows not being returned, vs being returned?

For sac above, there are no such changes so I don't understand why it's included in your example output.

For Paul, there are changes and don't understand why it's not included in your example output.

First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Just to help restate the task in more formal way let's start with this (not tested due to lack of DDL and sample data script)

-- Date interval params

declare @sd date ='20130101';

declare @ed date ='20150101';

-- get a set of (Name, ID)s which have any changes in Grade or sec

-- over the interval

select Name, ID

from Tracking_changes

where Systemdate between @sd and @ed

group by Name, ID

having max(Grade) <> min(Grade) or max(sec) <> min(sec);

Is it a step in right direction?
