Procedure can have both input\output parameters.
But function can have only input parameter.

But we can use function in Select Statement.

But Inside function we can’t use Try-Catch block.
Procedure can’t be call inside a function.But we can call function inside a Procedure.
Procedure can return 0 or n values (max 1024).But function can return only 1 value which is mandatory.
We can go for transaction management in procedure.But we can't go in function.

SQL statements anywhere in the WHERE/HAVING/SELECT section.
