A subroutine in a package can be called by another package or subroutine. However, if you declare a local subroutine, you can call that local subroutine only in the block that defines the local subroutine. It has the characteristics of object-oriented programming language and is the encapsula

For PL/SQL programming, this part of the Oracle database storage process is accurate, alas, it was difficult to learn when I was learning. In fact, it is very simple, is to learn a few times, learn not to learn again. Slowly, you can take care of it.The experience has been taught.
