SQL Error in my android project "no such column in table"

I'm trying to select from my database certain row by column "ID_TABLITSY" by using method "getid" but I get an error "no such column in mytable".
Database class code:
public class dbelper extends SQLiteOpenHelper{
private static final String DATABASE_NAME = "orginizer.db";
private static final int SCHEMA = 2;
static final String TABLE = "mytable";
static final String TABLE_DOM = "table_dom";
static final String TABLE_RAB = "table_rab";
public static final String COLUMN_ID = "_id";
public static final String COLUMN_NOTE = "note";
public static final String COLUMN_DATE = "date";
public static final String ID_TABLITSY = "idtable";
public dbelper(Context context) {
super(context, DATABASE_NAME, null, SCHEMA);
}
#Override
public void onCreate(SQLiteDatabase db) {
Log.d(LOG_TAG, "--- onCreate database ---");
db.execSQL("create table mytable(" + COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + COLUMN_NOTE + " TEXT, " + COLUMN_DATE + " TEXT, " + ID_TABLITSY + " INTEGER);");
db.execSQL("create table table_dom(" + COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + COLUMN_NOTE + " TEXT, " + COLUMN_DATE + " TEXT);");
db.execSQL("create table table_rab(" + COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + COLUMN_NOTE + " TEXT, " + COLUMN_DATE + " TEXT);");
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS "+TABLE);
db.execSQL("DROP TABLE IF EXISTS "+TABLE_DOM);
db.execSQL("DROP TABLE IF EXISTS "+TABLE_RAB);
onCreate(db);
}
public Cursor getid(int ID_TABLITS){
SQLiteDatabase db = this.getReadableDatabase();
String sqlQuery = "select * from mytable where ID_TABLITSY = " + ID_TABLITS + ";";
return db.rawQuery(sqlQuery, null);
}
}
and here the way i use this method in the other class
#Override
public void onResume() {
Cursor cursor = dbHelper.getid(1);
if (cursor.moveToFirst()) {
super.onResume();
db = dbHelper.getReadableDatabase();
userCursor = db.rawQuery("select * from " + dbelper.TABLE, null);
String[] headers = new String[]{dbelper.COLUMN_NOTE, dbelper.COLUMN_DATE, dbelper.ID_TABLITSY};
userAdapter = new SimpleCursorAdapter(this, android.R.layout.two_line_list_item, userCursor, headers, new int[]{android.R.id.text1, android.R.id.text2}, 0);
listView.setAdapter(userAdapter);
}
cursor.close();
}
Error code says that there is no such column but i definitely :

Closed 5 years ago.
I am trying to create two tables in SQLite database in my Android application but it shows the following errors. Basically, the second table that I am trying to create won't be created. Any help would be appreciated.
This is the error that I got:

This is my database helper class. Am I missing something?

This is my class to insert data:

Toast.makeText(this, "Please do not leave any field blank! ", Toast.LENGTH_SHORT).show();
return;
} else {
Hotels hotels = new Hotels();
hotels.setRoom_id(room_id);
hotels.setRoom_price(room_price);
hotels.setRoom_type(room_type);
hotels.setHotel_id(hotelID);
helper.insertRoom(hotels);
//Toast.makeText(this, "Data Added To The Database", Toast.LENGTH_SHORT).show();
}
}
}
public void onViewRoomButtonClick(View view)
{
if (view.getId()==R.id.viewRoom)
{
Intent intent = new Intent(RoomInfoActivity.this, ViewRoomContents.class);
startActivity(intent);
}
}
}

If you modified the database, for example add/remove table/column, you need to
uninstall the app from the emulator/device and then reinstall it.
If that not works, just go to File and click on Invalidate Caches/Restart

I've checked your DatabaseHelper and it has no problem.
Could you show the code for init database and insert data?
Maybe the issue come from initial steps.

Inserting Multiple records in a database

enter code hereAm making an application that displays a list of items in a listview and a button to add more items to the listview , and I want to insert those new items to the SQLite database using the same button .
I created a table with 2 Colons (ID , ITEM1 ) Like this :
public void onCreate(SQLiteDatabase db) {
String createTable = "CREATE TABLE " + TABLE_NAME + " (ID INTEGER PRIMARY KEY AUTOINCREMENT, " +
" ITEM1 TEXT) ";
db.execSQL(createTable);
}
but when i added 3 more Colons to the table , i could not insert any data to the database !!
I tried to search for solutions but didn't get any chance Well Am a Beginner in SQLite and its Confusing me, how can I solve this?

You have to add spaces here before each type:
String createTable = "CREATE TABLE " + TABLE_NAME + " (" +
COL1 + " INTEGER PRIMARY KEY AUTOINCREMENT," +
COL2 + " TEXT NOT NULL,"+
COL3 + " INTEGER NOT NULL,"+
COL4 + " INTEGER NOT NULL,"+
COL5 + " INTEGER NOT NULL);";
And Remove ID

Have you upgrade your db version ??
private static final int DATABASE_VERSION = 2;//from 1 to 2
private static class OpenHelper extends SQLiteOpenHelper {
OpenHelper(Context context) // constructor
{
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
//Changes in db mentioned here
}
}

Try writing the actual SQL until you get comfortable with String concatenation.
CREATE TABLEfoodlist_data (ID ID INTEGER
You need spaces around the table name, and you put ID twice. (You should name it as _id anyway)

How to save high scores and time in my game SQLite

I have a game in which I want to make a top 10 results and the results are going to be made of 2 things - difficulty (easy, medium, hard) and score(integer). So far I am trying for sometime now to understand how this SQLite works in Android studio and I am still confused but after reading several tutorials here is what I managed to put together: DBHandler class
public class DBHandler extends SQLiteOpenHelper {
private static final int DATABASE_VERSION = 1;
private static final String DATABASE_NAME = "highscores";
private static final String TABLE_DETAIL = "scores";
private static final String KEY_ID = "id";
private static final String KEY_TIME = "time";
private static final String KEY_DIFFICULTY = "difficutly";
public DBHandler(Context context){ super(context, DATABASE_NAME, null, DATABASE_VERSION);}
#Override
public void onCreate(SQLiteDatabase db) {
String CREATE_HIGHSCORES_TABLE = "CREATE TABLE" + TABLE_DETAIL + "("
+ KEY_ID + " INTEGER PRIMARY KEY, "
+ KEY_TIME + " TEXT, "
+ KEY_DIFFICULTY + " TEXT, ";
db.execSQL(CREATE_HIGHSCORES_TABLE);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_DETAIL); // tova maha starata tablica ako s16testvuva
onCreate(db); // tova q pravi nanovo
}
// Adding new score
public void addScore(int score) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_TIME, score); // score value
// Inserting Values
db.insert(TABLE_DETAIL, null, values);
db.close();
}
// Getting All Scores
public String[] getAllScores() {
// Select All Query
String selectQuery = "SELECT * FROM " + TABLE_DETAIL;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
// looping through all rows and adding to list
int i = 0;
String[] data = new String[cursor.getCount()];
while (cursor.moveToNext()) {
data[i] = cursor.getString(1);
i = i++;
}
cursor.close();
db.close();
// return score array
return data;
}
}
This class below, I don't know why it is even required but I saw it in every tutorial so I copy it...
public class Contact {
//private variables
int _id;
String difficulty;
String time;
// Empty constructor
public Contact(){
}
// constructor
public Contact(int id, String name, String _phone_number){
this._id = id;
this.difficulty = name;
this.time = _phone_number;
}
// constructor
public Contact(String name, String _phone_number){
this.difficulty = name;
this.time = _phone_number;
}
// getting ID
public int getID(){
return this._id;
}
// setting id
public void setID(int id){
this._id = id;
}
// getting name
public String getName(){
return this.difficulty;
}
// setting name
public void setName(String name){
this.difficulty = name;
}
and the last class
public class highscores extends Activity {
private ListView scorebox;
#Override
protected void onCreate(Bundle savedInstanceState) {
DBHandler db = new DBHandler(this);
scorebox = (ListView) findViewById(R.id.scorebox);
super.onCreate(savedInstanceState);
setContentView(R.layout.highscores);
Log.d("Insert: ", "Inserting ..");
db.addScore(9000);
Log.d("Reading: ", "Reading all contacts..");
}
}
I tried in the last class to put some data just to test the database but application crashes as soon as I click the button to open the database and this is where I gave up and decided to ask for help.
The error is a very long one:

There is syntax error in your sql.
android.database.sqlite.SQLiteException: near "TABLEscores": syntax error (code 1): , while compiling: CREATE TABLEscores(id INTEGER PRIMARY KEY, time TEXT, difficutly TEXT,
It should be space after TABLE.

SQLiteException: no such column error [duplicate]

This question already has answers here:
When does SQLiteOpenHelper onCreate() / onUpgrade() run?

Closed 6 years ago.
I have looked through SO and found many people having this same error, but they seem to be forgetting to add the column into the create statement or missing whitespace, neither of which I believe I did.
My logcat is as follows:
E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.gmd.referenceapplication, PID: 31988
android.database.sqlite.SQLiteException: no such column: QUANTITY (code 1): , while compiling: SELECT * FROM FTS WHERE (QUANTITY MATCH ?)

Thank you to anyone who can tell me why it is telling me the column "QUANTITY" is not being created, I really don't know.

If you change the schema you should increment DATABASE_VERSION so the database is upgraded.
