1.A stored procedure is a precompiled collection of
Transact-SQL statements stored under a name and processed
as a unit that you can call from within another Transact-
SQL statement or from the client applications.
2.Stored procedure performs an action.
3.A collection of SQL statements often combined with
Control-of-flow statements.
1.User Defined Functions are compact pieces of Transact SQL
code, which can accept parameters, and return either a
value, or a table. They are saved as individual work units,
and are created using standard SQL commands. Data
transformation and reference value retrieval are common
uses for functions.

1. User defined functions can be used in select statements.
Procedures can not be used.

always return the value.
3. Functions will take only input parameters. Procedures
can take input as well as output parameters.
4. Not all types of user-defined functions use
INSERT,UPDATE,DELETE statements(Only multi-statement table
valued functions can use). All procedures can use these
statements.
