JDBC Ada 7 lanhkah untuk mengakses database 1

JDBC • Ada 7 lanhkah untuk mengakses database: 1. Load the JDBC Driver 2. Define the connection URL 3. Establish the connection 4. Create a statement object 5. Execute a query or update 6. Process the result 7. Close the connection

JDBC try { // Class. for. Name("org. gjt. mm. mysql. Driver"); // Step 1 Class. for. Name("sun. jdbc. odbc. Jdbc. Odbc. Dri ver"); // step 1 } catch (Exception E) { E. print. Stack. Trace(); } // end catch

JDBC try { con = Driver. Manager. get. Connection("jdbc: odb c: Database 1"); //, "root", ""); // step 2 and 3

JDBC stmt = con. create. Statement(); // step 4 rs = stmt. execute. Query("SQL Query'"); // step 5 while (rs. next()) { // step 6 : : } // while

JDBC stmt. close(); // step 7 con. close();

Access Database • Microsoft Acess Database : db 1

Setting Access Database • Menset Database yang dipakai sebagai acuan dalam Program • Start -> Control Panel -> ODBC Data Source

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

Setting Access Database • Click OK • Data base db 1 siap diakses oleh Program

JDBC Program package jdbc 01; import java. sql. *; public class JDBCTest 01 { public static void main(String[] args) { Connection conn = null; Statement stmt = null; Result. Set rs = null; try { Class. for. Name("sun. jdbc. odbc. Jdbc. Od bc. Driver"); // step 1 } catch (Class. Not. Found. Exception cnfe) { System. err. println(cnfe); } catch (Exception E) { E. print. Stack. Trace(); } // end catch try { conn = Driver. Manager. get. Connection("jdbc: odbc: db 1"); // step 2 and 3 stmt = conn. create. Statement(); // step 4 rs = stmt. execute. Query("SELECT * FROM tabel 02"); while (rs. next()) { // step 6 System. out. print(rs. get. String("Nomer") + " "); System. out. print(rs. get. String("Judul") + " "); System. out. print(rs. get. String("Pengarang") + " "); System. out. print(rs. get. String("Penerbit") + " "); System. out. print(rs. get. String("harga") + " "); System. out. println("Oke"); } // while stmt. close(); conn. close(); } catch(SQLException sqle) { System. err. println("SQLException : " + sqle. get. Message()); } // end cacth } }

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.

Mysql Database • Mysql dapat didownload di : www. mysql. com/downloads • Extract and Just install it: Setup. exe • Mysql terletak di C: mysql • Aktifkan mysql admin dengan double click di : C: mysqlbinwinmysqladmin

Mysql Database • Inilah tampilannya • Atau tampak di pojok kanan bawah

Mysql Database • Mysql database : test 002 • Tabel : tabel 02

Java to mysql • JDBC Driver for My. SQL dapat di-download di : www. mysql. com/downloads dengan nama : My. SQL Connector/J 2. 0. 14 • Extract ke C: • JDBC Driver akan terletak di subdirectory C: mysql-connector-java-2. 0. 14

Java to mysql • Dengan JBUILDER, buat program (class) Java misalnya : JDBCTest 01. java • Project -> Project Properties -> Path -> Required Libraries -> Add. . . -> New, tuliskan nama library-nya, misal mysql-connectorjava, click Add. . .

Java to mysql • Pilih subdirectory C: mysql-connector-java-. . . , di mana JDBC driver untuk mysql diletakkan, click OK

Java to mysql • Library yang baru akan tampak seperti pada gambar, click OK

JDBC Program package jdbc 01; import java. sql. *; public class JDBCTest 01 { public static void main(String[] args) { Connection conn = null; Statement stmt = null; Result. Set rs = null; try { Class. for. Name("org. gjt. mm. mysql. Driver"); // Step 1 } catch (Class. Not. Found. Exception cnfe) { System. err. println(cnfe); } catch (Exception E) { E. print. Stack. Trace(); } // end catch try { conn = Driver. Manager. get. Connection("jdbc: mysql: //localhost: 3306/test 002", "rsn", "risanuri"); stmt = conn. create. Statement(); // step 4 rs = stmt. execute. Query("SELECT * FROM tabel 02"); while (rs. next()) { // step 6 System. out. print(rs. get. String("Nomer") + " "); System. out. print(rs. get. String("Judul") + " "); System. out. print(rs. get.

String("harga") + " "); System. out. println("Oke"); } // while stmt. close(); conn. close(); } catch(SQLException sqle) { System. err. println("SQLException : " + sqle. get. Message()); } // end cacth } }

JDBC Program dengan mysql • Setting tidak perlu dilakukan pada Control Panel • Perlu dilakukan setting pada Java Program • Driver JDBC disediakan oleh mysql dan harus di-download secara terpisah • Mysql memungkinkan memanggil Database lewat jaringan

Tambahan con = Driver. Manager. get. Connection("jdbc: mysql: //localhost: 3306/pasiendreritta", "r oot", ""); stmt = con. create. Statement(); stmt. execute.

Java to mysql • Setting Classpath, prosesnya sama dengan setting classpath yang lain – Pada Win 98, Start ->Run (sysedit), kemudian pada autoexec. bat tambahkan C: mysqlconnector-java-2. 0. 14, yang merupakan letak subdir JDBC Driver

Java to mysql

Java to mysql • Compile – myjava>javac JDBCTest 01. java • Buat subdir jdbc 01 di dalam : myjava • Letakkan JDBCTest 01. class pada subdir : myjavajdbc 01 • Eksekusi – myjava>java jdbc 01.
