[resolved] tMap left outer join to insert/update and delete records

Hi,
I have one problem about delete record from table. In my job, I take tAccessInput do left outer join via tMap with tPostgreSQLInput (I need to update some Access column with postgres table column). I want to update or insert row that exist in tAccessInput to Postgres table and to delete record that doesn't exist in Postgres table.
Can you tell me how to do it ? I read some posts that we can create two different outputs in tMap to tPostgreSQLOutput which one performs insert/update and the other output performs delete. Bud I don't know how to do this with left outer join.
Best regards,
Sophanna

Hi,
Sorry for asking repeated question. Could you tell me beside map these two table with primary key, do I need to give another criteria to get the rejected row that doesn't match this join.
