It doesn't look like it's going to work, but it's not. The code of the trigger does not compile with the INSERT, delete, and update commands that trigger themExecution plan. Instead, it is compiled and put into a buffer, so that whatever command triggers it, it can be reused effectively. The execution plan branch of a DML statement gives all the tri

Each programmer should be familiar with the Java.lang package, the Java.util package, and, to some extent, the contents of the Java.io package. Knowledge of other class libraries can beLearn whenever you need to. The classes on concurrency in the java.util.concurrent package should also be part of each programmer's basic toolkit.Don't invent the wheel again. If the things you want to do seem to be very common, it is possible that a class in the class library has already done so.
