Answer / aravind

Statement:
When you use normal statements compilation of statement or
parsing of statement will happen everytime. This is time
cosuming when u have mutliple queries to execute.

Statemtn s = conn.createStatement();
s.executeQuery();

Prepared Statement:
In prepared statement SQL query will be compiled or parsed
for the very first time and kept in some kind of pool. When
u execute one more time the same statement with different
values it saves the parsing time.

SQL select * from employee where employeeID=?,empName=?;
PreparedStatement ps = conn.PreparedStatement();
ps.execute(1,aru);
ps.execute(2,arya);

Callable Statement:

Callable statements are used to execute stored procedures
similar to java functions.
