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 :

CodePudding user response：

ID_TABLITSY is the name of the variable containing the column's name, not the name of the column:

String sqlQuery = 
    "select * from mytable where "   ID_TABLITSY   " = "   ID_TABLITS   ";";
