Troubleshooting: Slow Performance with Excel MS Query

Problem Description

I am experiencing a huge delay when running a Query in the Excel MS Query versus running the same script in VB Demo. VB Demo will return the data in 2 seconds while running the query in MS Query running for over 10 minutes. I am running Optimizer. Is something not configured correctly?


MS Query builds queries a little bit differently than I would write them. Copy the SQL Statement from MS Query into VB Demo and re-compare what's really going on. The actual query part should be the same, but the passing of data to Excel from MS Query would take additional time depending how much data is returned.

The best optimizer settings should be checking "Optimize data after an Insert or Update" and "Dirty Reads" option. See also: How to setup QODBC Optimizer and where are the Optimizer options for more.
