Last 5 rows of data

Tue, 10 Jun 2014 10:47:07 GMT

Hi,

I have a back end table that looks something like the file attached.

For each row and each Key I want to be able to look at previous 4 rows and count the number of Advisor lines and calculate the field 'Last5Count' as in the excel attached, could someone please suggest a solution.

Please note i have many more fields and have 800k rows worth of data.

Regards

Rahul
