Merging two unrelated tables

Is it possible to merge two unrelated tables together

 

Say for instance I have a Date table, with one column and three rows

 

Date

1-Jan-15

1-Feb-15

1-Mar-15

 

The I also have a Names table, with one column and three rows

 

Name

Rod

Jane

Freddie

 

Is it possible to create a DateName table, , with two columns and nine rows?

 

Date.........Name

1-Jan-15...Rod

1-Feb-15...Rod

1-Mar-15...Rod

1-Jan-15...Jane

1-Feb-15...Jane

1-Mar-15...Jane

1-Jan-15...Freddie

1-Feb-15...Freddie

1-Mar-15...Freddie

 

Thanks in advance

Hello @Lee_Mather

 

Yes you can do this in the Query Modeler, but you'll have to modifiy the structure of the tables in order to create a surrogate key" to mege the table.

 

In the table, you add a new column (SK for example) with the value "1" for all the record.

 

You do the same with the other table, and now you can merge the two queries, based on this fake relationship. Don't forget to check the relationship type with "full external" and it should be ok.

Great solution @Anonymous!

p.s. For other users that may need help on this purpose here is the solution explained:

 

1) Add to the two tables the same "index column" with a fixed index

2) Merge the two tables

5) And you have the result:

..if you want you can delete the "index colum".

 

#Good Coding To Everyone#

I have a similar issue when I created index columns for two of my tables to which I want to create a relationship, but in my case since I used DirectQuery, It says that the resulted query is not supported with Direct Query.

What would be the best workaround for this?
