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.
User-defined functions cannot make use of dynamic SQL or temp tables. Table variables are allowed. SET statements are not allowed in a user-defined function. The FOR XML clause is not allowed . User-defined functions can be nested; that is, one user-defined function can call another. The nesting level is incremented when the called function starts execution, and decremented when the called function finishes execution. User-defined functions can be nested up to 32 levels.
