Lookup stage generates blank values for non nullable columns
Posted: Tue Apr 01, 2014 5:13 am
Hi,
I have a scenario like 2 input stages one lookup and target stage.
My source tables are like
Table A
col1
a
b
c
Table B
col1,col2
a, 100
b, 200
Table A (main link),Table B (reference link) connected to lookup stage.
Lookup condition is continuous.
Lookup stage output should be like
Col1,Col2
a ,100
b ,200
c ,null
But in lookup stage output link in metadata properties Col2 is not null.
As null passing to non nullable column,
third row c ,null should be dropped.
Actually lookup stage generating blank value and passing row as c ,[blank].
Please suggest me how to handle blank spaces in lookup stage.
Thanks,
