what is difference between procedure and function,
procedure and trigger?
Answer Posted / roopesh kumar
Diff. B/W Procudure & Func......
(1) Proc. may or may not return value or more than one.
but func. must return a single value.
(2) We can call a func. in a select stmt. but func. should
only with IN parameter.
But we can't call a procedure inside a selct stmt.
because calling a procedure itself a PL/SQL block.
There is no too much diff. b/w proc. & func. but the thing
is that when we are looking to get back a single value we
should use func. in case of more than one then we should go
for proc.
Diff. b/w proc. & trigger..
(1) We have to call a proc. explicitly but trigger will
fire implicitly with assosiated event.
