DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JAVA & DATABASE

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC Introduction JDBC is basically used because it can access any database. JDBC uses drivers to connect to the database, which are categorized into four types. Jdbc has a set of exclusive interfaces and classes. Few steps to perform JDBC application.

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC Driver 1.Jdbc-Odbc bridge driver : This bridge driver can be used to connect to any existing database, I.e, ODBC compliant. 2.Native-API/partly Java driver : Converts JDBC calls into database specific calls for database such as SQl, Oracle etc. Driver is partly written in “Java” and partly in “C”. 3.Net-protocol/all-Java driver : This driver is used in Internet to connect to the database at different locations. This is supposed to be the most flexible driver. 4.Native-protocol/all-Java driver : Converts the JDBC calls into the network protocol used by DBMS’s directly. This is very much used in intranet access.

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC API for Database Interfaces : –Connection –Statement –Result set –Prepared statement –Result set Meta data –Callable statement –D/B Meta data Classes : –Driver manager –Date Time –Types –Date –Driver property –information –Time stamp

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC Ada 7 langkah untuk mengakses database: 1.Load Driver JDBC 2.Mendefinisikan Koneksi URL yang dipakai 3.Menghubungkan Koneksi tsb. 4.Menciptakan statement object 5.Mengeksekusi query atau update 6.Memproses Hasil 7.Memutuskan Koneksi

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC try { // Class.forName("org.gjt.mm.mysql.Driver"); // Step 1 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); // step1 } catch (Exception E) { E.printStackTrace(); } // end catch

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC try { con = DriverManager.getConnection("jdbc:odbc:Datab ase1");//,"root",""); // step 2 and 3

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC stmt = con.createStatement(); // step 4 rs = stmt.executeQuery("SQL Query'"); // step 5 while (rs.next()) { // step 6 : : } // while

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC stmt.close(); // step7 con.close();

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY Access Database Microsoft Acess Database : db1

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY Setting Access Database Menset Database yang dipakai sebagai acuan dalam Program Start -> Control Panel -> ODBC Data Source

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY Setting Access Database Tampil jendela ODBC Data Source Administrator Click System DSN-> Add-> pilih Driver (Microsoft Access Driver) -> Finish. Dalam hal ini kita memakai Access Database. Tentukan Letak File Database yang digunakan

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY Setting Access Database Click OK Data base db1 siap diakses oleh Program

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC Program package jdbc; import java.sql.*; public class JDBCApp { public static void main(String[] args) { Connection conn = null; Statement stmt = null; ResultSet rs = null; try { Class.forName("sun.jdbc.odbc.Jd bcOdbcDriver"); // step1 } catch (ClassNotFoundException cnfe) { System.err.println(cnfe); } catch (Exception E) { E.printStackTrace(); } // end catch try { conn = DriverManager.getConnection("jdbc:odbc:bukuJDB C"); // step 2 and 3 stmt = conn.createStatement(); // step 4 rs = stmt.executeQuery("SELECT * FROM buku"); while (rs.next()) { // step 6 System.out.print(rs.getString("No") + " "); System.out.print(rs.getString("Judul") + " "); System.out.print(rs.getString("Pengarang") + " "); System.out.print(rs.getString("Penerbit") + " "); System.out.print(rs.getString("harga") + " "); System.out.println(""); } // while stmt.close(); conn.close(); } catch(SQLException sqle) { System.err.println("SQLException : " + sqle.getMessage()); } // end cacth } }}

DEPARTMENT OF ELECTRICAL ENGINEERINGGADJAHMADA UNIVERSITY JDBC Program dengan Access Setting perlu dilakukan pada Control Panel, untuk menset Database yang dipakai Pada Java Program tidak diperlukan setting apapun Sun telah menyediakan driver secara otomatis untuk Access Hal ini tidak berlaku untuk Sistem Database yang lain, misal: mysql, oracle, dll.
