Hi @Anonymous, 

Are you able to supply some test data and required output data?

Hello, as this is sensitive data, I could hardly give you more information. However, the problem lies more with my lack of knowledge than with a bug.

Just use fake data that uses the same field and table structure, then you know what it means, but it enables other people to help you do what you need.  Just use random numbers and letters for text, as long is it is there in principle, it will enable you to get a solution quicker.

Hi @Anonymous Thanks for the data, what is your desired out put in Power BI.  why do you want one big table?  I can see that this is system data from the columns, are you looking to to ETL this and build a star schema, or have one table to use for visualisations? 

I will look at writing you a query to do this and post up later today.

The idea is to compare query 1 with query 2, in order to display in a new sheet only those names from query 1 that do not appear in query 2. The comparison is made between "Nom, prénom de l'inscrit" (query 1) and the merging of the "Nom de l'enfant" and "Prénom de l'enfant" columns.
