问题
I have many functions applied to rows in a tablix column. I need to sum all the rows in a tablix column. I am using reporting services 2005, so LOOKUP doesn't exist and I also do not have access to the SQL stored procedure.
回答1:
Your question is rather vague, but I'll take a crack at the problem. Let's say that you have a textbox in the tablix column called Textbox5. In a footer row (either a group footer or the tablix footer), you can use an expression like this:
=Sum(ReportItems!Textbox5.Value)
That will sum up the values in that textbox after the functions have been resolved in each row.

And aggregate function can be used only on report items place in Header or Footer !!!!
