In this tutorial, you are going to see the detailed description on how to create and execute the named blocks (procedures and functions).
Procedures and Functions are the subprograms which can be created and saved in the database as database objects. They can be called or referred inside the other blocks also.
Apart from this, we will cover the major differences between these two subprograms. Also, we are going to discuss the Oracle built-in functions.

Terminologies in PL/SQL Subprograms
Before we learn about PL/SQL subprograms, we will discuss the various terminologies that are the part of these subprograms. Below are the terminologies that we are going to discuss.
Parameter:
The parameter is variable or placeholder of any valid PL/SQL datatype through which the PL/SQL subprogram exchange the values with the main code. This parameter allows to give input to the subprograms and to extract from these subprograms.
These parameters should be defined along with the subprograms at the time of creation.
These parameters are included n the calling statement of these subprograms to interact the values with the subprograms.
The datatype of the parameter in the subprogram and the calling statement should be same.
