I am using receiver JDBC adapter. When I get the data, I have to update or inert into the sql database.
The problem is when i get a record, there is employee number in the record. I have to go to database, check if the record for employee number is there.
If the record is there, I have to update. If the record is not there, I have to insert.
Employee number is a unique key. Using that I have to find out from database if record exists or not
How do I do this?
