私はデータベースを扱っており、次の DataBaseHandling クラスがあります。
public class DatabaseHandler extends SQLiteOpenHelper {
// All Static variables
// Database Version
private static final int DATABASE_VERSION = 4;
// Database Name
private static final String DATABASE_MEASURES = "measuresDataBase";
// Measures table name
private static final String TABLE_MEASURES = "measures";
// Measures Table Columns names
private static final String KEY_ID = "id";
private static final String KEY_DATE = "date";
private static final String KEY_TIME_HOUR = "timeHour";
private static final String KEY_TIME_MINUTE = "timeMinute";
private static final String KEY_BE_INTAKE = "be_intake";
private static final String KEY_GLUCOSE = "glucose";
private static final String KEY_BOLUS = "bolus";
private static final String KEY_BASAL = "basal";
public DatabaseHandler(Context context) {
super(context, DATABASE_MEASURES, null, DATABASE_VERSION);
}
// Creating Tables
@Override
public void onCreate(SQLiteDatabase db) {
String CREATE_MEASURES_TABLE = "CREATE TABLE " + TABLE_MEASURES + "("
+ KEY_ID + " INTEGER PRIMARY KEY," + KEY_DATE + " TEXT,"
+ KEY_TIME_HOUR + " INTEGER NOT NULL," + KEY_TIME_MINUTE
+ " INTEGER NOT NULL," + KEY_BE_INTAKE + " REAL NOT NULL,"
+ KEY_GLUCOSE + " REAL NOT NULL," + KEY_BOLUS
+ " REAL NOT NULL," + KEY_BASAL + "REAL NOT NULL," + ")";
db.execSQL(CREATE_MEASURES_TABLE);
}
// Upgrading database
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// Drop older table if existed
db.execSQL("DROP TABLE IF EXISTS " + TABLE_MEASURES);
// Create tables again
onCreate(db);
}
// Adding new contact
public void addMeasure(Measures m) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_DATE, m.getDate());

values.put(KEY_TIME_MINUTE, m.getTimeMinute());
values.put(KEY_BE_INTAKE, m.getBolus());
values.put(KEY_GLUCOSE, m.getGlucose()); // Contact Name
values.put(KEY_BOLUS, m.getBolus()); // Contact Phone Number
values.put(KEY_BASAL, m.getBasal());
// Inserting Row
db.insert(TABLE_MEASURES, null, values);
db.close(); // Closing database connection
}
public Measures getLastMeasure(String date) {
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.query(TABLE_MEASURES, new String[] { KEY_ID,
KEY_DATE, KEY_TIME_HOUR, KEY_TIME_MINUTE, KEY_BE_INTAKE,
KEY_GLUCOSE, KEY_BOLUS, KEY_BASAL }, KEY_DATE + "=?",
new String[] { date }, null, null,
KEY_TIME_HOUR + " DESC, " + KEY_TIME_MINUTE + " DESC", "1");
if (cursor != null)
cursor.moveToFirst();
Measures m = new Measures(Long.parseLong(cursor.getString(0)), // id
cursor.getString(1), // date
Integer.parseInt(cursor.getString(2)), // timeHour
Integer.parseInt(cursor.getString(3)), // timeMinute
Double.parseDouble(cursor.getString(4)), // BE intake
Double.parseDouble(cursor.getString(5)), // glucose
Double.parseDouble(cursor.getString(6)), // bolus
Double.parseDouble(cursor.getString(7)) // basal
);
// return m
return m;
}
// Getting All Measures
public List<Measures> getAllMeasures() {
List<Measures> measureList = new ArrayList<Measures>();
// Select All Query
String selectQuery = "SELECT * FROM " + TABLE_MEASURES;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
// looping through all rows and adding to list
if (cursor.moveToFirst()) {
do {
Measures m = new Measures();
m.setId(Long.parseLong(cursor.getString(0)));
m.setDate(cursor.getString(1));
m.setTimeHour(Integer.parseInt(cursor.getString(2)));
m.setTimeMinute(Integer.parseInt(cursor.getString(3)));
m.setBe_intake(Double.parseDouble(cursor.getString(4)));
m.setGlucose(Double.parseDouble(cursor.getString(5)));
m.setBolus(Double.parseDouble(cursor.getString(6)));
m.setBasal(Double.parseDouble(cursor.getString(7)));
// Adding measure to list
measureList.add(m);
} while (cursor.moveToNext());
}
// return contact list
return measureList;
}
logcat は次を示します。
android.database.sqlite.SQLiteException: そのような列はありません: 基礎 (コード 1):、コンパイル中: SELECT id、date、timeHour、timeMinute、be_intake、ブドウ糖、ボーラス、基礎 FROM mesaures WHERE date=? ORDER BY timeHour DESC LIMIT 1
私はあなたのすべての助けに感謝します
