I have a stored Procedure that gives me the activity for a customer for a given time frame. It returns sperate variables for each field. ie.

Month Amount
Month2 Amount
Month3 Amount
etc,,,,,,
It does this in a 12 month increment. I would like to graph this data. I need a way to turn this into only two fields. On that contains all of the months and one that contain all of the amounts. Is there a way to do this?

Could you post an example of the returned data?
one way is to define the returned data with as
i.e.
select @variable_month as month, @variable_amount as amount.
now you have 12 rows with month and amount as the heading and the data as the value.

Using:
create table #temporary_table ...
 insert into #temporary_table (month,value) values  (@variable_month, @variable_amount)

The returned data looks as follows.

Month1 = Oct '08
Month2 =Nov '08
Month3 = Dec '08

Amount1 = 15.50
Amount 2 = 156.25
Amount3 = 456.00

If I used your suggestion, which sounds like what I am looking for, how would the data be returned?

You have two options to cycle through a loop to spit the data out:
Or issue sequentially
select @Month1 as month, @Amount1 as Amount
..
select @Month12 as month, @Amount12 as Amount

Or create a temporary table, and insert the data into it either via a loop or a sequential insert of the data.

Unfortunately, I do not have an example handy nor do you wish to alter the existing sp to return the data as a table.

how many variables will you have if the period you select is more then twelve months if such an option is available?  Or is the SP is always a twelve month report from an end point?

The sp is always a 12 month report. It will never have more than 12 variables.

The post at:

Deals to some extent with your question.  A link therein points to a method to use a temp table and populate the data.
http://www.sommarskog.se/arrays-in-sql-2005.html

Is an option available to change the results to output a comma separated list for months and amounts?

Yes it is possible to change the results if this will allow me to do what I want.

In this case, can the sp build a temporary table and return the contents rather then assembling the data in variables??

I adjusted the SP so that the variables where inserted into a temp table, then I parsed the table for the info for the chart. Works great. Thanks for the help and the tip about temp tables.
