Because it is permitted to call procedure inside the function.
What is Oracle inline function?
The function is created in-line, inside the query. It takes a NUMBER as input, it returns a NUMBER and its implementation invokes a procedure to to the actual work. This procedure is also defined in-line.
What is subprogram in PL SQL?
A PL/SQL subprogram is a named PL/SQL block that can be invoked repeatedly. If the subprogram has parameters, their values can differ for each invocation. A subprogram is either a procedure or a function. Typically, you use a procedure to perform an action and a function to compute and return a value.
What is procedure and function in Plsql?
PL/SQL has two types of subprograms called procedures and functions. Generally, you use a procedure to perform an action and a function to compute a value. Like unnamed or anonymous PL/SQL blocks, subprograms have a declarative part, an executable part, and an optional exception-handling part.
Can we write procedure inside function?
A function cannot call the procedure inside the program’s body.
Can we use procedure inside function?
You cannot execute a stored procedure inside a function, because a function is not allowed to modify database state, and stored procedures are allowed to modify database state. Therefore, it is not allowed to execute a stored procedure from within a function.
What is procedure and function in Oracle?
A procedure is a subprogram that performs a specific action. You specify the name of the procedure, its parameters, its local variables, and the BEGIN-END block that contains its code and handles any exceptions. A function is a subprogram that computes and returns a value.
What is pragma inline in Oracle?
The INLINE pragma specifies whether a subprogram invocation is to be inlined. Inlining replaces a subprogram invocation with a copy of the invoked subprogram (if the invoked and invoking subprograms are in the same program unit).
What is stub in Plsql?
A stub is a PL/SQL procedure or function which has the same header as the actual procedure or function. A stub for a package contains a stub or specification for each module in the package. In that case, a stub is generated for syntactical checking, and the compiler continues.
How do I run a procedure in PL SQL Developer?

What are the built-in functions in Oracle PL/SQL?
Oracle PL/SQL Stored Procedure & Functions with Examples. 1 Conversion Functions. These built-in functions are used to convert one datatype to another datatype. 2 String Functions. 3 Date Functions.
What are the characteristics of procedure subprogram unit in PL/SQL?
Below are the characteristics of Procedure subprogram unit in PL/SQL: Procedures are standalone blocks of a program that can be stored in the database. Call to these PLSQL procedures can be made by referring to their name, to execute the PL/SQL statements. It is mainly used to execute a process in PL/SQL.
Can you write an inline function in the SQL clause?
As would be understood from the code written above, we were able to write our inline function in With Clause, and use it in the SQL clause, which we wrote after With Clause. As I expressed earlier, this function was formed on the fly –in runtime– and expired when the code ended running.
What are procedures and functions in Oracle Database?
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.
