    Hello ;

    I have a dataset which kind of gives me the below output :

    Year Month TotalSales TotalProducts

    2013 1 23233 45

    2013 2 3344 43

    2013 3 232 11

    2013 4 2232 23

    I am trying to represent the above dataset in a table and a bar graph.

    Is there a way I can limit the months to the last three months.

    I am using the current month as a parameter.

    So suppose , I choose month 4 as a parameter , i would like to see the results only for the months 4,3 & 2 in the bar chart I am using ?

    Is there a way I can do it ?

    It depends on the query being used to get the raw data.

    It might be sufficient to add a "TOP 3 ... ORDER BY Year DESC, Month DESC" to the underlying query, assuming the filter condition to use the parameter is already in place. Hard to tell...

    However, dealing with a month number alone might lead to unexpected results.

    Example: What would you expect for month number = 1? And how does your current query is designed to apply the filter for the expected output?

    Kind of depends where you do the limiting... if you do it in the stored procedure, use something like

    SELECT...

    FROM ...

    [SomeDate] >= DATEDIFF(m,-3,GETDATE())

    Trying to subtract from a MONTH() value won't work.
