I was running a long query (in SQL Query Analyzer) today and after about 40 minutes, a temp file (qag7a.tmp) appeared on my pc. It seemed as though SQL server was using my local processor (processor was at 100% in the task manager). The temp file quickly used up all available disk space and did not disappear until I disconnected from SQL Server. I thought all of the processing should be done on the server. Does this relate to the SQL Server setup?
