OuterJoin inline

Hi, i have this problem, i have 3 table inline populated in this way:

Tableuno:
LOAD * INLINE [
    A,B
    1, aa
    2, ss
    3, ee
];
Tabledue:
outer join (Tableuno)
LOAD * INLINE [
    A,C
    1, xx
    4, yy
];
Tabletre:
outer join (Tableuno)
LOAD * INLINE [
    A,C,D
    2, cc,dd
    6, ee,ff
];

 

When i show in a table i see for example 2 rows:

A,B,C,D

2,cc,-,-

2,-,cc,dd

 

But i want have for result in the table only 1 row in this way:

A,B,C,D

2,ss,cc,dd

is possible?

Thanks

You can do this with a INNER join

inner join (Tableuno)
LOAD * INLINE [
    A,C,D
    2, cc,dd
    6, ee,ff
];

Ignore this is wrong!

I would use applymap() rather than joins.  The mapping tables in the example below have a data in a slightly dfferent sequence to your original loads, but give the answer you are looking for,

C_Map:
mapping LOAD * INLINE [
A,C
1, xx
4, yy
2, cc
6, ee
];

D_Map:
mapping LOAD * INLINE [
A,D
2, dd
6, ff
];


Tableuno:
load *
where C > '' and D > '' ;
LOAD
A,
B,
APPLYMAP('C_Map', A, '') AS C ,
APPLYMAP('D_Map', A, '') AS D
INLINE [
A, B
1, aa
2, ss
3, ee
];

This is about thinking of your data in QlikView terms and not as a database!
Here are a couple of useful blogs on the applymap function.
