JDBC Insert Preparedstatement

In this Tutorial we want to describe you a code that helps you in understanding JDBC Insert Prepared Statement.

JDBC Insert Preparedstatement


The java.sql package contain a prepared statement, This prepared statement interface is available from the Statement interface. This is used to pass parameters at runtime. In this Tutorial we want to describe you a code that helps you in understanding JDBC Insert Prepared Statement. For this we have a class Jdbc Insert Prepared statement, Inside this class we have a main method that include the list of following steps -

 import a package java.sql - this provides you a network interface that help in communicating between front end and backend in database.

  Loading a driver followed by calling a class.forname( ),this class accept a driver class as argument. The Driver Manager call getConnection (),which returns you a connection object and this is used to built a connection between url and database.

  prepareStatement ( ) : This method is useful when you want to execute the same statement object many times, This reduces the time of execution to use the same object.The method accept a sql object as parameter, that include the list of inserted values into the table set The String( ) : Set String XXX  is defined in prepared statement to substitute a value in the question  mark placeholder as string,int .In the code, we substitute a question mark value as string.executeUpdate ( ) :This method provides you the numbers of affected rows in the table and execute the statement in a given code.executeQuery ( ):This method provides you a set of records retrieved from a table in the database. The select  statement is used to obtain the records from the result set.

 next ( ) : This method  retain  you the next elements in a series.

Finally the print print the No, Name from a employee table present in database. In case there is an exception in try block, the subsequent catch block check and handle the exception.
