Question

What is the difference between a stored procedure and a user-defined function? Based on the Academic Database, identify and describe a scenario where it would be necessary to use a stored procedure or a user-defined function. Your answer should be addressed in 100 to 150 words.

Answer 1

Answer and Explanation:

Stored Procedure : It is an object that is pre-compiled. It seems to be the initially compile as well as those files are saved. It executes that compilation file while this has been called.

Functions : Through, when the function is called it is compiled as well as executed.  

The differences between the both is that -  

• Stored Procedure return null, singular, or various values while Function only return one value at a time.
• Transactions cannot used in the function but it can be used in stored procedure.
• Functions may be named from such a stored procedure, but still not likewise.
• Stored procedures may have an input or output arguments, but the function still contain arguments for input.
• With the Academic Database situation, this is useful to use saved protocol anytime you choose to update / delete a participant, course, teachers, etc. Stored procedures are useful where the information or tables layout is to be altered.
