Note:- procedure may or may not return value.function must
return value
Procedure return one or more value & function return only
single value.
Pakages are groups of functions,procedures,sql blocks
goruped together in a single unit.
Package & packagebody are two different thngs. Variable
defined in packages are global & they can use in anywhere
in packagebody. Variable defined in packagebody have
limited scope. & they can used in defined limit only.
