JDBC (connection to Oracle) ____oracle

JDBC Programming Steps:
----Java-Oracle Data connection (under Lomboz_eclipse environment)
1. Locate the JDBC Folder →lib folder in the Oracle Database installation folder →classesl2.jar
Import this jar package in 2.lomboz_eclipse
Import Method:
Create a project, right-click on the project name to select Build Path→add External archives→
Select Classesl2.jar for Import

3. Create a new program to write code to connect with Oracle
The steps are as follows:
1. Instance Driver class
Class.forName ("Oracle.jdbc.driver.OracleDriver");
2. Establish a connection to the database
Connection conn = Drivermanager.getconnection ("Jdbc:oracle:thin:
@192.168.8.1:1521:yuewei "," Scott "," Tiger ");
3. Send data to the database
Statement STM = conn. Creatstatement ();
4. Execute statement (SELECT statement)
ResultSet rs = stm.executequery (SELECT * from dept);
5. Display statements
Rs.getstring ("Deptno");

The

Complete code is as follows:
Import java.sql.*; public class Testjdbc {public static void main (string[] args) {ResultSet rs = null; Statement stmt = null; Connection conn = null; try {class.forname ("Oracle.jdbc.driver.OracleDriver");//new Oracle.jdbc.driver.OracleDriver (); conn = Drivermanager.getconnection ("Jdbc:oracle:thin:@192.168.0.1:1521:yuewei", "Scott", "Tiger"); stmt = Conn.createstatement (); rs = Stmt.executequery ("SELECT * from dept"); while (Rs.next ()) {System.out.println (rs.getstring ("Deptno"));//system.out.println (Rs.getint ("Deptno"));} catch (ClassNotFoundException e) {e.printstacktrace ();} catch (SQLException e) {e.printstacktrace ();} finally {try { if (Rs!= null) {Rs.close (); rs = null;} if (stmt!= null) {stmt.close (); stmt = null;} if (conn!= null) {conn.close (); conn = null; The catch (SQLException e) {e.printstacktrace ();}} } }
