other solution is using the CTE and PIVOT like the follow script, in the sample I define the tables, but you can use your defined tables and only use the CTE statement, I wish resolve the problem :

That seems really complex compared to the cross tabs approach. At least for me.:-P

Everything was working fine but got the requirement change.Idea is:

a. base table can have multiple values of ID based on different books but can have only two values for object (juice and/or nojuice). b. nobase table can have multiple values for an ID based on different books with different values of Values for their Type.

output should be calculated as:

c. In final output, we need one entry per ID with Object "juice" as priority. That is, if there is only juice value for an ID then it will be taken, if nojuice only then it will be taken, if for an ID, there are both, then Juice will be taken and nojuice entries should be removed from point d calculation..

d. once object type "juice" or "nojuice" for decided for an ID, also we need to consider, which book for that ID has max value for "value" column. Only that book has to be considered PLUS the final "value" should contain net of all "Value" (in case the ID has both juice and nojuice, then only consider books with juice for netting the value)

To get this query, i would use nested CTEs (or subqueries) first using a RANK() function to determine which products I will include, then ROW_NUMBER() on the result to get the book with highest the highest value and finally get the aggregates over this.

If you want a coded answer from me, you need to provide at least consumable sample data.

I strongly recommend you do yourself a favor and start posting data in a readily consumable format as previously requested on this and many other posts.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
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.
