Troubleshooting
Problem
A report with multiple queries joined into a single query that retrieves data from a single data source will send multiple SQL Queries down to the database rather than a single query that joins each query into 1 final result.
Symptom
Report takes a long time to run, fails with timeout or causes memory errors with the QueryService.
