What are the similarities and differences between procedures and functions?
A procedure is compiled once and can be called multiple times without being compiled. A function returns a value and control to calling function or code. A procedure returns the control but not any value to calling function or code. A procedure has support for try-catch blocks.
What is the relationship between a function and a procedure?
A function returns a value and a procedure just executes commands. The name function comes from math. It is used to calculate a value based on input. A procedure is a set of commands which can be executed in order.
What is the difference between a function and a stored procedure?
The function must return a value but in Stored Procedure it is optional. Even a procedure can return zero or n values. Functions can have only input parameters for it whereas Procedures can have input or output parameters. Functions can be called from Procedure whereas Procedures cannot be called from a Function.
What is the difference between procedure and function with example?
Function is used to calculate something from a given input. Hence it got its name from Mathematics. While procedure is the set of commands, which are executed in a order.

What is the difference between ‘or’ and ‘is’ keywords in a procedure?
Keyword ‘OR REPLACE’ instructs the compile to replace the existing procedure (if any) with the current one. Procedure name should be unique. Keyword ‘IS’ will be used, when the stored procedure in Oracle is nested into some other blocks. If the procedure is standalone then ‘AS’ will be used.
