Kusto

[mackenziehall]

I have a Kusto query that works fine individually. When I attempt to Append Query and either choose Append Queries or As New, the query fails with a 400. Is this a known bug? Do you need any other information?

There is a known bug where doing a join or union (append queries is a union) on different databases will not work.

I thought this might be the issue but the sources are in the same database.

Hi @mackenziehall ,

It works fine in my test. I would suggest you upgrade your Desktop to the latest version if needed. Another try could be removing the optional parameters to test.

Best Regards,
