Trigger is invalid in Oracle

Question

Some of the triggers in my database become invalid after certain changes on the tables. But it seems that they are still working. The only problem I have is if I use SQL Develop

Answer 1

Not a big issue at all.

Just right click on them to recompile and you're good to go... I'm writing this from my own experience.

If there are any errors with the code you've just changed they will appear so that you can fix it. The compiler will tell you where are the problems (line numbers, variable names, etc) in case of errors.
