Microsoft SQL : The column 'Name' was specified multiple times for '_'.

Hi Community,


In my Power Query, I have a strange error after filtering a column on a value.


The error message is : "Microsoft SQL : The column 'Name' was specified multiple times for '_'"


Despite the error message content, I don't have multiple occurences of column 'Name' in my query.


Thanks in advance for your help

I just got this error when Appending two tables together where the columns had the same name but in different case.  One was all Caps and the other was mixed case:  CUSTOMER and Customer.  The crazy part is that the query looks fine in the editor.  You get the error on refresh.

It happens sometime when you have bring data from multiple tables in Table grid.

But when you remove the relationship field it goes away.

Based on the screenshot, I guess the query has more than one field with "Name" as columnname...  Please check and have unique alias names....

 Verify, if you can see multiple column names with name "Name" by navigativing to "Advanced Editor". You could get this error, when you merge queries, so validate from which query you get duplicate names. And change the column names before doing merge. It solves the issue.
