hello
in fabric dataflow, I am joining two excel files via several columns.
file1.col1 inner join file2.col1
file1.col2 inner join file2.col2
how is it possible to use file1.col join file2.col only if file1.col4 has a value?
thanks

Hi @arkiboys
Thanks for using Microsoft Fabric Community
Here's how to join two Excel files in Fabric Dataflow with an inner join based on multiple columns, considering a value in a separate column. Fabric Dataflow offers a powerful tool called Filter that allows you to achieve this conditional join.
I hope this information helps. Please do let us know if you have any further queries.
Thank you.
Could you create one (or more) custom column (populated with values only as per your conditions) and then use the custom column in the join instead of the original column(s)?
Or maybe you can edit the power query code in Advanced Editor to facilitate your needs.
(Otherwise, I would consider posting this in the Power BI desktop forum because this is essentially a universal Power Query question, not specific to dataflows gen2, and there may be some Power Query experts in that forum)

thank you for your reply however I am looking for a way to do condition on inner join when merging the two datasets.
Hi @arkiboys
After using the filter option, you can see the File1 that contains the columns which have only values.
You can see the result as below as there is only one common column.
I hope this information helps.
Thank you.
thanks for your message however your test is not as per my requirement in the original thread.
Hi @arkiboys
Apologies for the inconvenience from my end.
Could you please elaborate on the issue you are encountering by sharing additional details, such as screenshots, would be very helpful in understanding the problem and guide you in better way.
Thank you.
hi,
here is the scenario:
1- two sources
2- each source has columns as follows:
3- file1.col1, file1.col2, file1.col3, file1.col4
4-file2.col1, file2.col2, file2.col3, file2.col4
5- I would like to do an innerjoin using the merg functionality in dataflow on multiple columns as follows
6- the sql format of the join is like this but want to know how to do this in dataflow using merge
file1.col1 = file2.col1
and
file1.col2 = file2.col2
and
--use these columns in join if file2.col3 is not null and file2.col3 > 0
(
file1.col3 = file2.col3 --only if file2.col3 is not null
and file1.col4=file2.col4 --only if file2.col4 > 0
)
