db创建较简语法示例

...............
public static final String TABLE_NAME = "notes";
public static final String CONTENT = "content";
public static final String ID = "_id";
public static final String TIME = "time";
.............
//在 onCreate（）中建表

@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL("CREATE　TABLE"+TABLE_NAME+"("
    +ID+"INTEGER PRIMARY KEY AUTOINCEREAMENT,"+CONTENT+"TEXT NOT NULL,"+TIME+"TEXT NOT NULL");

}
