Average of values in variable ranges

Question

Post Author: Graybane
CA Forum: Charts and Graphs
I am trying to generate a trend values that use variable ranges. For instance, I want a 12 month trend developed from preceeding 1 year + 1 month average, then preceeding year + 2 months average, then preceeding year + 3 months average and so on. I only want the values for the report for the 12 monthly values. This is all complicated by being a group function. Basically I am looking at priorities for requests in a single field and developing how long it takes to resolve the request based on another field which is what is used to develoe the averages for the trend. I have tried several methods and never gotten a good trend. The total average is correct if I do not do any weighting. Has anyone had any success with this? Are there any examples I can look at. Does anyone have any recommendations? Thanks for any help

I'm not entirely following you, Visakh, but I have a SQL Task setup in which I have an expression that makes a call to a db2 database such as the abbreviated set example below.  The list of IDs in the IN statement must come from another  SQL Server
database.   In the past I have  gotten the list of IDs, put them in a recordset and then put that in a for loop to iterate and make one call to db2 for each and every ID.   The single ID example can literally take days to run for 100,000 IDs.
 Therefore, I want to pull the entire set of results back at one time via a single (or at least fewer calls than there are IDs) DB2 call using 'in' instead.  Maybe I am overlooking something but I don't quite see how your example will get me where
I want to go.  
Set Example
SELECT 
   A,
   B
FROM 
    Table 1, 
    Table 2, 
WHERE 
    Joins   
    AND PRSNEUP.ID in  ( This is where I want a list of IDs )
Single ID Example
SELECT     A,  
 B
FROM   
  Table 1,      Table 2, 
WHERE     
Joins        AND PRSNEUP.ID =  ( VariableContainingASingleID
