Re: Left outer join of two tables

Hi
yes, you can do left outer join in tMap component. I have created a job like this:
tFileInputCSV_1:
1,Alise,39
2,Bluce,49
3,Zlan,39
4,Yan,59

tFileInputCSV_2:
Alise,39
Bluce,49
Eliy,54
Ally,32

Please see the screenshot

Hello Shong !
Sorry to reply to this (very) old thread, but I'm facing a similar issue, and I can't see the screenshot you provided.
Could you please show it ?
Thanks !
