values there no any RETURN word.

Answer / mohammad sajid

Although both functions and sp's are prcomiled sql
statements there exists some differences between them.

1. Functions must return a value(scalar,inline table or
multi statement table) whereas stored proc may or may not
retun a value.
2.Functions can return a table whereas stored procs can
create a table but can't return table.
3. Stored procs can be called independently using exec
keyword whereas function are called using select statements.
4. Stored procs can be used to change server configuration
(in terms of security-i.e. setting granular permissions of
user rights) whereas function can't be used for this
5. XML and output parameters can't be passed to functions
whereas it can be with sp's.
6.transaction related statement can be handled in sp
whereas it can't be in function.
7. stored procedures can call a funtion or another sstored
proc similarly a function can call another function and a
stored proc.The catch with function is that no user defined
stored proc can be called.Only extended/system defined
procs can be called.

Hope this will be helpful and if there's any correction let
me know.

means we cannot perform insert,delete,update and create
operations on the database.
Stored Procedures can affect the state of the database by
using insert,delete,update and create operations.

2)Functions are basically used to compute values
stored procedures are basically used to process the task.
