Error "Key didn't match any rows" for VIEW - cannot refresh my reports

Hi all,


Thanks for reading


I've been trying to build a report recently and when refreshing, I have been facing the error

"The key didn't match any rows in the table 





I am connecting to a view in our impala database with the advanced editor code below:




    Source = Impala.Database("******"),
    zzz_Schema = Source{[Name="zzz",Kind="Schema"]}[Data],
    zzz_results = zzz_Schema{[Name="zzz_results",Kind="View"]}[Data]



and every night when there is new data inserted into the view and I try to schedule a refresh, it fails with the same error above.


The weird thing is, if i run a simple select query on the impala view like so before refreshing:


"select * from zzz.zzz_results limit 10"


PowerBI refresh runs completely fine and doesn't have the "keys didn't match any rows" issue!


I've tried both direct query and import, nothing seems to work so far. 


I haven't been able to find anything about connecting to a view and it causing any issues that I am facing so I was wondering if anyone could help at all?





@Anonymous From this thread it appears a fix works in Power Query ->

Re: Expression Error.: The key didn't match any rows in the table

you can make this error occur if you:

  1. connect to a database
  2. select any table and load it
  3. click home - edit queries
  4. click source under applied steps
  5. click advanced options in the popup
  6. type SQL statement e.g. select * from [yourtablename]
  7. click ok
  8. click close and apply
  9. You now see the error above (Expression.Error: The key didn't match any rows in the table)


  1. click home - edit queries
  2. under applied steps, remove navigation
  3. click close and apply
  4. The error is fixed"

I have seen this thread but for some reason there is no option to insert an SQL statement on the source, possibly because it is an Impala source?


Hi @Anonymous ,

Yes, Impala source still not supports a SQL Query.

Best Regards,
