Answer / suri
when we sent a sql stmt in to oracle sever the server
splits statemts in to mutiple stmts, checks wheather valid
or not, if it is valid it is stored in the shared pool,
where as in the normal stmt parsing will be done every time
in prepared parsing will be done only once, naxt time
onwards values will be sent to the place holders

Answer / anjani kumar jha
prepared statement work same as the statement,but there r
some differences.
wen u submitting the query first time following things happened
1)compiling the query
2)executing the query
3)sending results back to the program
2nd time onwards
1)executing the query directly
2) sending results back to the program

Hey this is an interface.
in the jdbc API they designed all the interface. which you
can use any interface based on that you can create the
implemented class method.
for this you can call in the core java design
pattern..abstract factory pattren..
you can try to see the API you can understand more.
preparedstatement---pre compiled statement.
first time it's compile and second time it will pass
dynamically.
make sure that should be done in DB side only once.
one time compile and next time passing the values into the
query then execute.
overall story behind this one time compile many times execute.

Answer / nagashree
Prepared statements are used due to its 2 advantages.
Advantages:
1) We can give dynamic values.
2) The statement will be compiled only once, it need not be
compiled each & every time we give new values.
