unable to update field from one table to another

[DM2017]

Hi,

I am trying to update one field(serverslno) in a table  from another table (which is key column primary key of the table) based on a join condition, but it's not working.

I have a table actor inserting data to actor_new

tmysqlinput(actor) >> tmap>>tmysqloutput(actor_new) >>tmap>>tmysqlout(actor)

ID genrated in actor_new should go to one column called serverslno in actor. first insert is working fine but update not working.

Screenshots attached. 

Please help.

Hi,

actor_id of "rr" flow must be populated in the tMap as it is the update key for the update.

[manodwhb]

in tMap,you have not mapped the Key column(that is input column for actor_id).

@manodwhb, what is the added value compared to the previous answer?

@TRF I understood. But this is not that case, here I want to update serverslno of actor with key column of actor_new. Previously it was a look up. but this is straight forward.

[TRF]

actor_id field is ticked as the Update Key for the update operation so it cannot be null.

As it is not mapped in the preceding tMap it is null so you need to add it.
