I am new to DCN, can I use it to detect updates on a column in my table along with inserts in that table ? I am referring to this
回答1:
Yes, you can - Change Notifications made for that. You need to register СN listener with query to watch (it can a whole table select * from your_table
or part of it select column1 from your_table where column2='xxx'
) and callback function . You should understand that it is async mechanism changes will not detect immediately, but after some time.
Your documentation's link shows way how to implement it using JDBC.
Read it if you want to use Oracle PL/SQL for that.
