PL/SQL DBMS outputDbms_output is a built-in package that is able to display output display debug information and send messages from PL/SQL blocks, subroutines, packages and triggers. We have used this package in all of our tutorials.Let's take a look at a small snippet that will display all the user tables in the database. Try to list all the table names in the database:BEGINDbms_output.Put_Line(user | | ); for T in ( select table_name from User_tab

Problem Thinking Chapter I. What is a bug? The textbook 29~31 page has a general idea of the bug, which is simply that the behavior of the software is different from the user's expectations, which is called a bug. This makes me very confused, so many people in the world, it is certain that every software will be different from many people's expectations, ah, so not every software is a bug?

To achieve these two requirements should be said not too high, pay attention to more practice on it. At pre
