You may already have one or two free autonomous databases at OCI. Why then would you want a lower tier database offering, a database that is not autonomous? It turns out there are many reasons why you may want this. No matter what your reason is, setting it up is pretty easy. One thing before…
I often want to use the constants defined in packages also in my SQL. It has in the past never worked and it for the most part still does not. If I have a a package like this to simplify my code for what department it is I’m looking at. This now allows using dept_info.c_accounting…
Views are great. They simplify design, makes code look more elegant and hides complexity. They also enables reuse by putting complex code in just one place instead of in every accessing piece of code. But… There once was a large project that has been churning away for a long time.
