Hi @Rohit Kulkarni ,
Thankyou for using Microsoft Q&A platform and thanks for posting your query.
As I understand your question here, you are trying to perform merge on data in SQL server tables using Upsert option in copy data activity. However, it is failing with error for one of the tables. Please let me know if my understanding is incorrect.
The error says 'Server is not responding'. This looks like an intermittent issue from source side. Could you please confirm if
- that's happening for the same table all the time ?
- If only that particular table is considered to be copied , others being inactive for one run, is that still failing?
- What is selected in the keycolumns for upsert functionality?
Looking forward for your response. Thanks !
