Hi,
I created some jobs in TOS in order to implement Insert-Update between tables from different schemas on Redshift.
For both cases, I used ELT components, using "Mapping Redshift". No problem for "Insert" task.
Actually, I am not able to implement UPDATE. Use case: One table on a schema that has to update another table on a different schema. This is what I've done:
The error that the job returns is "single-row subquery returns more than one row".
I tried to use also tRedshiftOutput component and tRedshiftRow for the update, and in this case everything is ok. I have to use ELT component because is much faster with lots of data to move.
I wish you can help me!
Really thank you!
