Combining two rows into one row (conditionally)

Hi all, 

 

I am trying to find a solution for the following and am wrecking my brain so any help is appreciated, I have two tables that look as follows:

 

Table 1 - Required:

 

Name   Exam           Required     

John   English        YES          

John   French         YES         

 

Table 2 - Obtained:

Name   Exam           Obtained   

John   English        YES               

John   German         YES

 

And what I want to end up with is this "combined" table:

 

Name   Exam           Required   Obtained   

John   English        YES        YES         note: the two rows have combined

John   French         YES        <null>

John   German         <null>     YES

 

Can anyone give me pointers? I am wrecking my brain trying to solve this.

 

Many thanks!

 

Jeroen

    Appended the query, transposed the table, reordered the columns, merged the columns, split the columns by position, removed columns, then transposed table, and did clean up.
