Ghost queries from MySQL
Hello everyone,
Does someone know how and why I am getting ghost queries in my power query?
The record does not exist in the DB, I have tried running the query though the DB, but yet when I run it in Power Query I get null values for most of the columns and some values for some.
Please explain to me how can this happen.
Thanks a lot.
Kind regards,
S
Hi lastephanieee,
The issue here might be caused by power query cache, joins, or transformations. Please try below steps:
- Clear power query cache and refresh the query preview, close and reopen the power bi.
- Check if the power query uses a JOIN which results in unmatched/null rows.
- Inspect query generated in power query, use View Native Query if available. Try running that exact SQL manually in MySQL directly to compare results.
- Check if the query uses views or triggers, if you are querying a view or a table with triggers, they might return unexpected rows.
- Make sure you are using the latest MySQL ODBC or .NET connector to avoid compatibility issues.
