I'm having problems joining 3 tables to provide a 4th table in the correct
format. I believe I need a FULL OUTER JOIN but does not give the result that
I require.See below:

Example 1
Table: Names                Table: Friend
Name    Tel    email    PostCode        Name    friend    email
Jim    1    aa    I            Dave    yes    cc
Ted    2    bb    J            Will    yes    dd
Dave    3    cc    K            Zac    yes    ff
Will    4    dd    L            Byron    yes    gg    

Table: Details
Name    email    Town    PostCode
John    ee    A    M
Zac    ff    B    N
Byron    gg    C    O
Will    dd    D    L
Gary    hh    E    P
Ted    bb    F    J

Combined table: Result
Name    Tel    email    Town    PostCode    friend
Jim    1    aa        I
Ted    2    bb    F    J
Dave    3    cc        K        yes    
Will    4    dd    D    L        yes
John        ee    A    M
Zac        ff    B    N        yes
Byron        gg    C    O        yes
Gary        hh    E    P



Example 2
Table: Names                Table: Friend
Name    Tel    email    PostCode        Name    friend    email
Jim    1    aa    I            Gareth    yes    ii
Ted    2    bb    J            Tony    yes    jj
Dave    3    cc    K            Ken    yes    kk
Will    4    dd    L            Lloyd    yes    ll        

Table: Details
Name    email    Town    PostCode
John    ee    A    M
Zac    ff    B    N
Byron    gg    C    O

Ted    2    bb        J
Dave    3    cc        K            
Will    4    dd        L        
John        ee    A    M
Zac        ff    B    N        
Byron        gg    C    O
