Analysis should produce errors when not using aggregation functions after summarize #125

Closed davidnx closed 11 months ago

davidnx commented 1 year ago

Example query:

datatable(a:string, b:string) [
    'a', 'b',
    'c', 'd',
]
| summarize a by b

This query is obviously incorrect (notice that a is passed after summarize, instead of some aggregation function like take_any(a)). While this query indeed fails (as expected) when submitted to a real Kusto cluster, the Nuget package accepts this as valid and doesn't produce any diagnostics. Kusto Explorer also doesn't show any squiggles or issues for this query until I attempt to execute it.

Tested with Microsoft.Azure.Kusto.Language 11.3.1 (I couldn't test with 11.3.2 yet due to https://github.com/microsoft/Kusto-Query-Language/issues/124)

Thanks for the report. You are correct. This should be an error.

This has been fixed and should show up in the next release.
