What is the difference between Stored Procedure (SP) and User Defined Function (UDF)?

A

Following are some major differences between a stored procedure and user defined functions:
UDF can be executed using the “SELECT” clause while SP’s can not be.
UDF can not be used in XML FOR clause but SP’s can be used.
UDF does not return output parameters while SP’s return output parameters.
If there is an error in UDF its stops executing. But in SP’s it just ignores the error and moves to the next statement.
UDF can not make permanent changes to server environments while SP’s can change some of the server environment.
