1) functions are used for computations where as procedures
can be used for performing business logic
2) functions MUST return a value, procedures need not be.
3) you can have DML(insert, update, delete) statements in a
function. But, you cannot call such a function in a SQL query..
eg: suppose, if u have a function that is updating a table..
you can't call that function in any sql query.
- select myFunction(field) from sometable;
will throw error.
4)We can call a function from a procedure, but it is not
possible to call a procedure from a function
