Statement interface----createStatement() method is useful
to create statement object and to execute simple queries...

PreparedStatement interface---derived from the Statement
interface...preparestatement() method used to create
preparedstatement object and used to execute queries with
unknown parameters or where in the parameters are provided
at the run-time

CallabaleStatement interface----derived from the
preparedstatement interface and helpful in executing stored

# 3
there are 3 types of statements used in jdbc

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 we can save the 99 parsings.

The callablestatement is used to call the storedprocedures.
