Hi all,
I have a query I wrote for an SSRS report. When I run the query in SSMS its slow like it takes 7 minutes to run but eventually gives me results. When I try to run the report, it does not ever finish loading. In fact it crashes my visual studio. Can anyone give me some insight on how to fix this? Thanks,
