We have a requirement, we will use DBCO to create connection with external database Oracle, and we need to modify(when it exist, it will update when it doesn't it insert) a lot of rows into table in Oracle. so I need help about this two question:
1. Because we have a lot of data to insert into Oracle,so how do we insert our internal table into Oracle in our ABAP program?
2. Sometimes we have to insert data when it doesn't exit, or we need to update data when it exist, so how do we realize this function in oracle?
Thanks for your sincerely answer.
