Answer / rashmi
there are 3 types of statements used in jdbc
------
1.createStatement()
2.preparedStatement()
3.callableStatement()
createStatement returns the object of statement.through this we can call methods belongs
to the statement interface.preparedStatement returns the object of preparedstatement.through this we can call methods belongs
to the preparedstatement interface.
The difference b/w statement and preparedstatement is :
if we use statement the sql querry parses by the database server each and every time.when
we send the request. but by using preparedstatement the sql querry parses only once and that
parsed querry is used every time.
for example if there are 100 sql statements by using statement 100 parsings are necessary.
but by using preparedStatement the parsing is happened only once.so we can save the 99 parsings.
The callablestatement is used to call the storedprocedures.
