retrieve particular column between different columns of sqlite databse in android

Here is the code, by this I can retrieve all the columns data from the database. But the problem is that now I want to retrieve only one column, that is my requirement.link1st link 2nd link3rd
word_list = new ArrayList<>();
SQLiteDatabase sd = mydb.getWritableDatabase();
Cursor cursor = sd.query("stickerstable",null, null, null, null, null, null);
if (cursor.moveToFirst()){
do{
word_list.add(new data_items(
cursor.getInt(cursor.getColumnIndex(ID)),
cursor.getString(cursor.getColumnIndex(STICKER_AUTHOR)),
cursor.getString(cursor.getColumnIndex(STICKER_NAME)
)));
}while (cursor.moveToNext());
cursor.close();
sd.close();
}

You can use rawQuery instead of query
Cursor cursor = sd.rawQuery("SELECT YOUR_COLUMN FROM stickerstable",null);
replace YOUR_COLUMN with the name of column you want to retrieve you can even use your Constants like this
Cursor cursor = sd.rawQuery("SELECT " + ID + " FROM stickerstable",null);
or a better way to use String.format
Cursor cursor = sd.rawQuery(String.format("SELECT %s FROM stickerstable", ID),null);
UPDATE
you can use query and specify the column in the second argument
Cursor cursor = sd.query("stickerstable",new String[]{ID}, null, null, null, null, null);
when you pass null means get all columns

How to iterate through all Contentresolver entries?

I have a database in my app, which I fill with data and an ID.
Then I request the database with the ID's I want:
Cursor cursor = contentResolver.query(uriPath, null, "ID = ?", new String[]{id1, id2, etc.}, null);
This retrieves me a cursor with all requested ID's .
How can I retrieve all objects in my UriPath ?

Just enter the Uri and leave the rest null
Cursor cursor = contentResolver.query(uriPath, null, null, null, null);

Changing order of listview results from SQlite

I have a listview in my application that displays records according to the primary key _ID field with the lowest _ID number first. How can I change that so it is the highest _ID number first in the listview? i.e reverse the order.
The db query currently generating the listview is below. Thanks!
public Cursor fetch() {
String[] columns = new String[] { DatabaseHelper._ID, DatabaseHelper.SLOC, DatabaseHelper.FLOC, DatabaseHelper.DSNM, DatabaseHelper.SDATE, DatabaseHelper.STIME };
Cursor cursor = database.query(DatabaseHelper.TABLE_NAME, columns, null, null, null, null, null);
if (cursor != null) {
cursor.moveToLast();
}
return cursor;
}

use this query:
Cursor c = mDb.query(DATABASE_TABLE, rank, null, null, null, null, yourColumn+" DESC");

You can use rawQuery method to hit any custom query like this and add ORDER BY ASC or DESC as you wish.
public Cursor fetch() {
String queryString = "SELECT * FROM tablename ORDER BY _id DESC"
Cursor cursor = sqLiteDatabase.rawQuery(queryString);
if (cursor != null) {
cursor.moveToLast();
}
return cursor;
}

Where clause is not working for long in android SQLite

I am trying for select statement in android SQLite
i am able to select all records in a cursor if i do below
String tableName = "Test";
String[] columns = {mobile};//mobile has a datatype number in db
Cusrsor c = m_sqlLiteDatabase.query(tableName, columns, null,null, null, null, null);
c.getCount(); // 11
but does not return any value if i add a conditon as below
long mobile = 123456;
m_sqlLiteDatabase.query(tableName, columns, "mobile=" + mobile ,null, null, null, null);
c.getCount(); // 0
is anything i am doing wrong?
how to use long

try to change your query code line with this
m_sqlLiteDatabase.query(tableName, columns, " mobile = ? ", new String[]{String.valueOf(mobile)} ,null, null, null);
Reference
query(String table, String[] columns, String selection,
String[] selectionArgs, String groupBy, String having,
String orderBy)

Android- Getting a single value from a database table using cursor

I'm using cursors to retrieve data from a database. I know how to retrieve entire columns to use on listviews and such, but I'm struggling to find a way to retrieve a single value.
Let's say I have a table with two columns ("_id" and "Name") and I have ten records (rows) in that table. How would I get, for example, the Name in the third row? Considering I defined a cursor that reads that table:
public Cursor getMyNameInfo() {
SQLiteDatabase db = getReadableDatabase();
SQLiteQueryBuilder qb = new SQLiteQueryBuilder();
String sqlTables = "MyNames";
qb.setTables(sqlTables);
Cursor c = qb.query(db, null, null, null,
null, null, null);
c.moveToFirst();
return c;
}

Instead of c.moveToFirst() use c.moveToPosition(2) (Cursor indexes are zero-based hence '2' is the third record).
Remember to check that the Cursor has valid data first though.
EDIT:
Once you've moved the cursor to the 3rd record as I explain above, use the following to just get the value of the "Name" column.
String theName = c.getString(getColumnIndex("Name"));

Cursor cursor = dbHelper.getdata();
System.out.println("colo" + cursor.getColumnCount() + ""
+ cursor.getCount());
cursor.moveToFirst();
if (cursor != null) {
while (cursor.isAfterLast() == false) {
String chktitle = title.trim().toString();
String str = cursor.getString(cursor.getColumnIndex("title"));
System.out.println("title :: "
+ cursor.getString(cursor.getColumnIndex("title")));
System.out.println("date :: "
+ cursor.getString(cursor.getColumnIndex("date")));
System.out.println("desc :: "
+ cursor.getString(cursor.getColumnIndex("desc")));
if (chktitle.equals(str) == true) {
tvAddfavorite.setText("Remove Favorite");
break;
}
cursor.moveToNext();
}
}
cursor.close();

Add a WHERE clause:
qb.appendWhere("_id = 2");

Thanks to the answers above I created the following method to give the value of an item from another column but in the same row.
public String getValueFromColumn(int position, String tableName, String columnToGetValueFrom) {
SQLiteDatabase db = getReadableDatabase();
SQLiteQueryBuilder qb = new SQLiteQueryBuilder();
qb.setTables(tableName);
Cursor c = qb.query(db, null, null, null,
null, null, null);
c.moveToPosition(position);
String neededValue = c.getString(c.getColumnIndex(columnToGetValueFrom));
return neededValue;
}
Hope it helps anyone.
