Merge tables when direct query

Hello, I was hoping someone could help me please?

 

I have been given access to a  dataset that contains multiple tables, and it comes through in Direct Query, so I dont see these in Power Query. Is there a way for me to merge these tables please?

 

Thank you

    Hi , you can still merge tables in Power BI when using DirectQuery mode. However, the process is a bit different than when using Import mode.

    When using DirectQuery mode, merging of tables is done through relationships between the tables in your data source. 

    Create a relationship between tables in DirectQuery mode:

    1. In the Manage Relationships dialog box, click the "New" button.
    2. Select the first table you want to relate to another table from the dropdown list.
    3. Select the column in the first table that you want to use as the relationship key.
    4. Select the second table that you want to relate to the first table.
    5. Select the column in the second table that you want to use as the relationship key.
    6. Click "OK" to save the relationship.

     

    Keep in mind that when using DirectQuery mode, some features in Power BI, such as certain types of calculations and transformations, may not be available or may be limited. Additionally, the performance of your report may be impacted by the size and complexity of your data source.

      Anonymous Thank you for your reply . I've tried the above but when I select the the frist table , all the other direct query tables are not an option in the second dropdown ?

      I have three tables that all have a completed date field, I need to put these into a filter to keep all data on one page to "This Year"

      I hope that extra info helps?

    All this does is create a relationship. It is not at all the same as joining/merging tables

    Hi,

    Did you consider as well the DAX function like INTERSECT, UNION, NATURALLEFTOUTERJOIN... that are performing join operation between tables ?

    Hope it might help
