1. Function is mainly used in the case where it must return
a value. Where as a procedure may or may not return a value
or may return more than one value using the OUT parameter.
Â
2. Function can be called from SQL statements where as
procedure can not be called from the sql statements
3. Functions are normally used for computations where as
procedures are normally used for executing business logic.
4. You can have DML (insert,update, delete) statements in a
function. But, you cannot call such a function in a SQL query.
5. Function returns 1 value only. Procedure can return
multiple values (max 1024).
6.Stored Procedure: supports deferred name resolution.
Example while writing a stored procedure that uses table
named tabl1 and tabl2 etc..but actually not exists in
database is allowed only in during creation but runtime
throws error Function wont support deferred name resolution.
7.Stored procedure returns always integer value by default
zero. where as function return type could be scalar or table
or table values
8. Stored procedure is precompiled execution plan where as
functions are not.
Â
9.A procedure may modify an object where a function can only
return a value The RETURN statement immediately completes
the execution of a subprogram and returns control to the caller.
