1. Playing with SQLite Database  SQLite : Database specific name for Android Application  For windows there are several kind of database name : Mysql, SQL server, Oracle, Microsoft Access, etc. (Microsoft excel is not database!) a. Create SQLite Database File b. Database Query (Scripting) c. Database Query (Interface) 2. Steps to create Database application in Android

1. Open “SQLite Database Browser 2.0 b1.exe” 2. Ctrl+N (File-New Database) 3. Select directory and give name you want to save database file (file name for database, example : data)

1. Create Database (Create New Database)  unavailable in SQLite 2. Drop Database (Delete Existing Database)  unavailable in SQLite 3. Create Table and its Field (Create New Table and its Field) 4. Drop Table (Delete Existing Table) 5. Insert Data (Add New Data) 6. Update Data (Modify Existing Data) 7. Select Data (Read Existing Data) 8. Delete Data (Delete Existing Data)

CREATE TABLE (namafield1 tipedatafield1, namafield2 tipedatafield2, namafield3 tipedatafield3,…, namafieldN tipedatafieldN) Example : Assumption : Table name : kelasmobapp Field names : NIM (integer primary key), Nama (Text) CREATE TABLE kelasmobapp (nim int,nama text)

DROP TABLE Example : Assumption : Table name : kelasmobapp DROP TABLE kelasmobapp

INSERT INTO VALUES (datafield1,datafield2) Example : Assumption : Table name : kelasmobapp Field names : NIM (integer primary key), Nama (Text) Data inserted : NIM= , Nama=’Heri Suprapto’ INSERT INTO kelasmobapp VALUES ( ,’Heri Suprapto’)

UPDATE SET = WHERE = Example : Assumption : Table name : kelasmobapp Field names : NIM (integer primary key), Nama (Text) Data updated : NIM= , Nama=’Heri Suprapto’ will be updated to be ’Herawati Suprapti’ UPDATE kelasmobapp SET Nama=‘Herawati Suprapti’ WHERE NIM=

SELECT,,,…., FROM Example : Assumption : Table name : kelasmobapp Field names : NIM (integer primary key), Nama (Text) Data read : NIM SELECT nim FROM kelasmobapp All field : SELECT * From kelasmobapp

DELETE FROM WHERE = Example : Assumption : Table name : kelasmobapp Field names : NIM (integer primary key), Nama (Text) Data deleted : NIM= , Nama=’Heri Suprapto’ will be deleted DELETE FROM kelasmobapp WHERE NIM=

1. Open “SQLite Database Browser 2.0 b1.exe” 2. Ctrl+N (File-New Database) 3. Select directory and give name you want to save database file (file name for database example : data) 4. Make a name for the database table, and klik add 5. Add minimum a field name and type, click create 6. Add other field as you want 7. After finish, you can click create 8. Save the database (File-Save Database), you now have a database file : data (without extension) 9. Make new data to all field, use GUI and query script.query script 10. Close “SQLite Database Browser 2.0 b1.exe”

1. Create Class DataBaseHelper.java to your project 2. Set DB_NAME in DataBaseHelper.java to database file name of your project which you have created when preparing the SQLite Database file (data) 3. Load your database file in DDMS, steps : a. Click File Explorer tab b. Find your package (if not existing, run your project in the first time then try to find again) c. Create folder databases d. In databases folder, load your database file e. You can view the table and the content by clicking on the database file and click SQLite Browser 4. Create your xml interface file 5. Create your own script

1. Create Class DataBaseHelper.java to your project 2. Set DB_NAME in DataBaseHelper.java to database file name of your project which you have created when preparing the SQLite Database file (data) 3. Make new class for activity, example testing.java: 4. Make your database file based on script (in onCreate method): try { datavar.execSQL("create table tabel(no int,status teks, alamat teks,nim teks,nama teks);"); } catch (Exception exception) { Toast.makeText(Cobadb1Activity.this, "Database sudah ada", Toast.LENGTH_SHORT).show(); } Note about datavar : SQLiteDatabase datavar; //before onCreate DataBaseHelper db1 = new DataBaseHelper(this); // inside onCreate datavar = db1.getWritableDatabase(); // inside onCreate 5. Create your own script

1. CREATE datavar.execSQL("create table tabel(no int,status teks, alamat teks,nim teks,nama teks);"); 2. INSERT 3. SELECT 4. UPDATE 5. DELETE

datavar.execSQL("insert into tabel(Status,no,Alamat,NIM,Nama) values ('" + Status + "','" + no + "','" + Alamat + "','" + NIM + "','" + Nama + "'); ");

ContentValues CV = new ContentValues(); CV.put("Status", Status); CV.put("No", no); CV.put("Alamat", Alamat); CV.put("NIM", NIM); CV.put("Nama", Nama); datavar.insert("tabel", null, CV);

final Cursor db; db = datavar.rawQuery("select * from tabel;", null); db.moveToFirst(); nama.setText(db.getString(4)); nim.setText(db.getString(3)); alamat.setText(db.getString(2));

datavar.execSQL("update tabel set nama='" + Nama + "',alamat='" + Alamat + "',status='" + Status + "' where NIM='" + NIM + "';");

datavar.execSQL("delete from tabel where nama='" + Nama + "';");
