Oracle PL/SQL Tutorial 31-Parameter Modes in Procedure(IN,OUT,INOUT) with Example | Javainhand
In this video, we will learn parameter modes in Oracle procedures - IN, OUT, and INOUT. Understanding these parameter modes is crucial for writing efficient and effective stored procedures in Oracle databases.
We'll start by explaining what each parameter mode means:
IN: Parameters marked as IN are used to pass values into the procedure. These values are read-only within the procedure, meaning they cannot be modified.
OUT: Parameters marked as OUT are used to return values from the procedure. These values are write-only within the procedure, meaning they cannot be read but can be modified.
INOUT: Parameters marked as INOUT are used for both passing values into the procedure and returning values from the procedure. They can be read and modified within the procedure.
Throughout the video, we'll demonstrate each parameter mode with practical examples, showing you how to declare and use them effectively in your procedures.
