0x80040E4E Error - OLE DB or ODBC

[Anonymous]

Hello all.

I have this strange error. I say strange because I can refresh the data on the Query Editor but I can't connect it to the model when I do "Apply". I get the 0x80040E4E error and I have literally no idea why. I just know it started occuring after I grabbed data from a folder and I created a function to get the filename in a column.

Any thoughts?

Thanks in advance!

I'm pulling from a Dataflow and getting this same error and the same vaguely helpful error message. 

Would be excellent if the error identified the fields in question.

Whatever is going wrong here is also not being caught by Table.RemoveRowsWithErrors() either.

I had the same issue, i had duplicated a table iun power query and this issue poppedup.

It worked for me when i cleared everything in the duplicated table advanced editor and replaced the content from first table(which i duplicated from), then it worked.

Hope this helps.

I followed these steps

Step 1: Go to the Model section from the left side of the Power BI Desktop

Step 2: Delete all the relationships amongst the tables that have been created by Power BI itself while you were working with the Power Query Editor

Step 3: Click 'Refresh visual and data' option in Home (besides the Transform Data button)

It worked and loaded the new data and also applied the automations done in the query editor.

It works...!

This worked for us as well. In addition to the OLE ODBC error we were getting a note about not being able to find data sources we had deleted months ago and were not mentioned anywhere in the model. Thanks!

Hey there, I ended up through a naive search on the same issue. The 'Solution' post gave me the right indication. It turned out be cause by the filename of the csv files, I was collecting from a sharepoint. Renaming the files, using alphanumeric characters only, solved it for me.

I solved this issue ,Re-install Oracle Client

Hi,
I came across a similar problem but its source was duplicate data on a column that created a relationship with a different table. Even worse, he didn't appear on the table causing the error.

I am trying to get data from Google Analytics to Power Bi but for page and page views field I am getting ' failed to save modifications to the sever . Error returned: 'OLE DB or ODBC error: [DataSource.Error] There was an internal error.. ;. Can you please help me with this issue

Hi @Anonymous,

It seems that the error throws out when you apply the changes, right? In your scenario, please try to update the desktop to the version 2.42.4611.901 released in 1/20/2017.

If issue persists, please try to share the sample folder data source and sample .pbix file to reproduce the issue if possible.

Best Regards,
Qiuyun Yu

After messing around with the file, I solved it. It has to do with character support, as I had cubic and degree sign on the code and it was read as "?". I changed the encoding to Western Europe and it is solved. But it was not intuitive, as the error code did not point to this. Anyway, I hope this may help someone with the same problem.

Thanks for your support.

Como você fez para alterar a configuração dos dados ? Para Europa ocidental ?

I don't understand this solution but have a similar problem. One of my errors is 

So no mention of any column. And by the way there are no data type changes in the query editor. 

Do you have any ideas how to fix? I may post this in a few places.

Thanks

Works! I changed the data type to correctly reflect the data and it works now. Thanks.

Dear Svalen, 

Was your file a csv? I am facing the same issue with an excel file (error after grabbing data from a folder). Still nothing worked so if you have any idea?

Hi, check your encoding in the Advanced Editor (first line I believe or by clicking source options in the next steps).
