Answer Posted / shar
alternative ans lot similar to subu's.
to both files add a dummy column let say
File A
col1,dummy1
1,1
2,1
3,1
4,1
5,1
6,1
7,1
8,1
9,1
10,1
And for File B
col1,dummy2
6,2
7,2
8,2
9,2
10,2
11,2
12,2
13,2
14,2
15,2
Using col generator . Now join the two files using join
stage with full outer join. With key col1.
Then the output will be:
Left_col1, dum1, right_col1, dum2
1 1 0 0
2 1 0 0
3 1 0 0
4 1 0 0
5 1 0 0
6 1 6 2
7 1 7 2
8 1 8 2
9 1 9 2
10 1 10 2
0 0 11 2
0 0 12 2
0 0 13 2
0 0 14 2
0 0 15 2
Now assign the output to Transformer stage where at
constraints we mention:
DSLink6.dummy1 = 1 And DSLink6.dummy2 <> 2
DSLink6.dummy1 = 1 And DSLink6.dummy2 = 2
DSLink6.dummy1 <> 1 And DSLink6.dummy2 = 2
Then at three targets we map
Target 1 : left_col1
Target2 : left_col1
Target3: Right_col1
Hence the o/p.
