Ahm what are you expecting us to do to help.
Have you tested the query (procedure) in SSMS.
Have you then tried getting the data back in the client, you may be trying to get just too much data or you may have an infinte loop in you query!

In my DataSet has two Datables, one about 2,000 records,another 13,000 records.
When I click report button, I'll wait about 30min ,and finally, get the out of memory.
I think my query string is ok, I want to know how can I load large data using ReportViewer Control.
Is there any better control for report large data?

when you load the data in the dataset - without reportviewer - how long does it takes and how much memory is used?

just seconds less than 1min, the memory is not very high, about 30%,40%.
