SQLiteException:没有此类列:basic(代码1)

I'm working with databases and I have the following DataBaseHandling class:

我正在使用数据库，我有下面的数据库处理类:

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_HOUR, m.getTimeHour());
    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;
}

The logcat shows:

logcat显示:

android.database.sqlite.SQLiteException: no such column: basal (code 1):, while compiling: SELECT id, date, timeHour, timeMinute, be_intake, glucose, bolus, basal FROM mesaures WHERE date=? ORDER BY timeHour DESC LIMIT 1

android.database.sqlite。SQLiteException:没有此类列:basic(代码1):，编译时:选择id, date, timeHour, timeMinute, be_acceptance，葡萄糖，bolus, basic FROM mesaures WHERE date=?限时订货

I would thank all your help

Use a space after KEY_BASAL column . As your table column name was not correct , the table was created without this column. So after modifying code re-install your database or change version.Then you will get correct table with columns

在key_basic列之后使用空格。由于您的表列名称不正确，因此在没有这个列的情况下创建了表。因此，修改代码后，重新安装数据库或更改版本。然后，您将得到具有列的正确的表。

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" + ")";


if (cursor != null && cursor .getCount()>0){

        cursor.moveToFirst();

}

There is a problem that you have missed a space at the Key_basal and also placed an extra comma at the end of your onCreate method. Your code :

有一个问题是您错过了key_basic的一个空格，并在onCreate方法的末尾添加了一个额外的逗号。你的代码:

// 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);
}

It should be :

应该是:

// 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);
}

#3

Autoincrement KEY_ID or put some data to KEY_ID as well as put your full log cat here:

自动增加KEY_ID或将一些数据放到KEY_ID中，并将完整的日志cat放在这里:

String CREATE_MEASURES_TABLE = "CREATE TABLE " + TABLE_MEASURES + "("
        + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + 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" + ")";

#4

Remove , End of Query

删除，查询结束

KEY_BASAL + "REAL NOT NULL," + ")";
                          ^
                          | Here

And Use Space For Concat Strings

并使用空间来处理字符串。

KEY_BASAL + "REAL NOT NULL," + ")";
             ^
             | Here

I got this error while using junit tests. And my error was simple but evil.

我在使用junit测试时犯了这个错误。我的错误很简单，但却是邪恶的。
