User-defined functions combine the advantages of stored procedures with the capabilities of SQL predefined functions. They can accept parameters, perform specific calculations based on data retrieved by one or more SELECT statement, and return results directly to the calling SQL statement.
Before You Begin. Limitations and restrictions. User-defined functions cannot be used to perform actions that modify the database state. User-defined functions cannot contain an OUTPUT INTO clause that has a table as its target. User-defined functions can not return multiple result sets. Use a stored procedure if you need to return multiple result sets.
