I have 4 different database connections in Oracle SQL Developer. All of them have the exact same set of packages and procedures. Every time I change something in my scripts I have to run it on all of the connections one-by-one. Is there no way to run it on all the connections at the same time?
I'm afraid that you can only execute SQL developer queries on different connections using the GUI.
You should, however, be able to acheive what you want using SQLPlus instead.
