public class BatchUpdationDemo {
public static void main(String args[]){
Connection con=null;
Statement st = null;
try {
Class.forName(“oracle.jdbc.driver.OracleDriver”);
con=DriverManager.getConnection(“jdbc:oracle:thin:@localhost:1521:ORCL”,”scott”,”tiger”);
st = con.createStatement();
st.addBatch(“insert into eshusoft values(‘myuser’,'mypwd’)”);
st.addBatch(“update eshusoft set password=’mypwd2′
where ¬†username=’myuser’”);
st.addBatch(“delete from eshusoft where username=’myuser’”);
int b[] = st.executeBatch();
System.out.print(“rows updated: “+ b.length);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
