E/SQLiteLog: (1) duplicate column name: Temperatur - duplicates

Question

I just started to work with android studio. i am also new in the programming of apps or anything else. Now i try to build my first app. i get the failure massage: "E/SQLiteLog: (1) duplicate column name: Temperatur"
In the other Threads i don´t find the right solution.
My Code:
public class FangbuchDbHelper extends SQLiteOpenHelper {
public static final String DB_NAME = "fangbuch.db";
public static final int DB_Version = 1;
public static final String TABLE_KARPFEN = "Karpfen";
public static final String COLUMN_ID = "id";
public static final String COLUMN_DATUM = "Datum";
public static final String COLUMN_ZEIT = "Uhrzeit";
public static final String COLUMN_WINDRICHTUNG = "Windrichtung";
public static final String COLUMN_WINDSTAERKE = "Windstärke bft";
public static final String COLUMN_TEMPERATURA = "Temperatur außen";
public static final String COLUMN_TEMPERATURW = "Temperatur Wasser";
public static final String COLUMN_HPAGESTERN = "hPa gestern";
public static final String COLUMN_HPAHEUTE = "hPa heute";
public static final String COLUMN_HPAMORGEN = "hPa morgen";
public static final String COLUMN_MOND = "Mond";
public static final String COLUMN_GEWICHT = "Gewicht";
public static final String COLUMN_FOTO = "Foto";
public static final String TABLE_MEERFORELLE = "Meerforelle";
public static final String COLUMN_ID2 = "id2";
public static final String COLUMN_DATUM2 = "Datum2";
public static final String COLUMN_ZEIT2 = "Zeit2";
public static final String COLUMN_WASSERSTAND = "Wasserstand";
public static final String COLUMN_WINDSTAERKE2 = "Windstärke2 bft";
public static final String COLUMN_WINDRICHTUNG2 = "Windrichtung2";
public static final String COLUMN_TEMPERATURW2 = "Wassertemperatur";
public static final String COLUMN_STROEMUNG = "Strömung";
public static final String COLUMN_FOTO2 = "Foto2";
public static final String SQL_CREATE =
"create table " + TABLE_KARPFEN + "(" +
COLUMN_ID + " integer primary key , " +
COLUMN_DATUM + " text not null, " +
COLUMN_ZEIT + " text, " +
COLUMN_WINDRICHTUNG + " text, " +
COLUMN_WINDSTAERKE + " integer, " +
COLUMN_TEMPERATURA + " integer, " +
COLUMN_TEMPERATURW + " integer not null, " +
COLUMN_HPAGESTERN + " integer, " +
COLUMN_HPAHEUTE + " integer, " +
COLUMN_HPAMORGEN + " integer, " +
COLUMN_MOND + " text, " +
COLUMN_GEWICHT + " REAL, " +
COLUMN_FOTO + " text); ";
public static final String SQL_CREATE2 =
"create table " + TABLE_MEERFORELLE + "(" +
COLUMN_ID2 + " integer, " +
COLUMN_DATUM2 + " text not null, " +
COLUMN_ZEIT2 + " text, " +
COLUMN_WASSERSTAND + " text, " +
COLUMN_WINDSTAERKE2 + "integer, " +
COLUMN_WINDRICHTUNG2 + " text, " +
COLUMN_TEMPERATURW2 + " integer, " +
COLUMN_STROEMUNG + " text, " +
COLUMN_FOTO2 + " text); ";
public FangbuchDbHelper(#Nullable Context context) {
super(context, DB_NAME, null, DB_Version);
}
#Override
public void onCreate(SQLiteDatabase sqLiteDatabase) {
sqLiteDatabase.execSQL(SQL_CREATE);
sqLiteDatabase.execSQL(SQL_CREATE2);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
Log.w(FangbuchDbHelper.class.getName(), "Upgrading database from version " + oldVersion + "to "
+ newVersion + ", which will destroy all old data");
db.execSQL("DROP TABLE IF EXISTS " + DB_NAME);
onCreate(db);
}
}
At the beginning i had duplicate column names. But now i have changed this.
But i still get this message.
Whats my mistake? Can someone help me? Thanks
Regards Ulf

Answer 1

I'm not a SQL(ite) expert, but it's noticeable that your column names Temperatur außen and Temperatur Wasser contain a space and are inserted unquoted in the create table statement, which presumably causes the error. According to SQLite Keywords, there are three or four ways of quoting an identifier in SQLite - you may want to choose one for the definitions of COLUMN_TEMPERATURA and COLUMN_TEMPERATURW.
