** Understanding Oracle SQL Parameters: IN, OUT, and IN/OUT

Oracle SQL functions and procedures can have parameters categorized as IN, OUT, or IN/OUT. Knowing the differences between these parameter types is crucial for effective programming.

IN parameters pass values into a function or procedure, but they are read-only. OUT parameters return values from a function or procedure to the calling environment. IN/OUT parameters allow both input and output modifications.

Mastering these parameter types enables developers to create more powerful and flexible SQL functions and procedures in Oracle databases.
