How to get specific value from DB by id

How to get specific value from DB by id.
This is my table: TABLE-RECORDS-(name of table) and KEY-ID , KEY-PRICE ... I'm trying to get KEY-PRICE by KEY-ID and can not. How to do it?

I don't know if this is exactly what you are looking for, but this is the query.
SELECT key-price FROM table-record WHERE key-id='id number you need';

// please change the column names of database if i have mistaken
public Cursor getCursor(int id) {
SQLiteDatabase db = this.getReadableDatabase();
String from[] = {"key-price"};//this is the edit1
String where = "key-id=?";//this is the edit2
String[] whereArgs = new String[]{String.valueOf(id)+""}; //this is the edit3
Cursor cursor = db.query(true, table-records, from, where, whereArgs, null, null, null, null);
return cursor;
}
//just call this function and see the magic
private int getPrice(int id) {
Cursor c = getCursor(id);
int price=-1;
if(c != null)
{
while(c.moveToNext){
//assuming price is an integer
price = c.getInt(0);//edit 4
// use these strings as you want
}
}
return price;
}

SQLite rawQuery with multiple WHERE clauses

I have retrieved 2 values through the putExtra and getStringExtra method in another class. BOth these values are correct. I need to use these 2 values in my SQL query:
final Cursor cursor = sdb.rawQuery("SELECT match_player_name FROM match_response WHERE match_date=? AND " +
"match_response =?"+new String [] {String.valueOf(date),String.valueOf(response)}, null);
I am unfamiliar using rawQuery with more than 1 condition. Have I the correct syntax? I have a record in my SQLite database satisfying this condition.

This is an example:
Cursor cur = database.rawQuery("select name from Table where ID=? and SubCategoryID=?",
new String [] {String1,String2});

public Cursor getMachineServices(){
SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("select row1, from maquina where something = x AND somethingelse = y", new String[]{});
return c;
}
Then on your activity where you want to display it you must do:
Database db;
db = new Database(yourActivity);
Cursor c = db.getMachineServices);
if (c.moveToFirst()) {
do {
String machines
c.getString(c.getColumnIndex("row1"));
//you can use the variable machines where you want
} while (c.moveToNext());
}

getting row id from sqlite using other fields as where condition

sir, how can i return the rowid of my database depending on the inputs name, number? this code just return the value 0 everytime. my primary key is KEY_ROWID. thanks for help in advance
//get rowid
public long getRowId(String name, String number)
{
// TODO Auto-generated method stub
String[] columns = new String[]{KEY_ROWID, KEY_NAME, KEY_NUMBER};
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, KEY_NUMBER+ "=" +number, null, null, null, null);
long rowid = c.getColumnIndex(KEY_ROWID);
return rowid;
}
here is how i access it
public void onClick(View arg0) {
nameChanged = sqlName.getText().toString();
numChanged = sqlNumber.getText().toString();
GroupDb info = new GroupDb(EditDetails.this);
info.open();
long rowid = info.getRowId(name, num);
info.updateNameNumber(rowid, nameChanged, numChanged);
Toast.makeText(getApplicationContext(), rowid+" "+nameChanged+" "+numChanged, Toast.LENGTH_LONG).show();
ArrayList<Contact> searchResults = info.getView();
MyCustomBaseAdapter mcba = new MyCustomBaseAdapter(EditDetails.this, searchResults);
mcba.updateResults(searchResults);
Toast.makeText(getApplicationContext(), "Update Successful!", Toast.LENGTH_LONG).show();
info.close();
}
});

From the fine manual:
public Cursor query (String table, String[] columns, String selection, String[] selectionArgs, String groupBy, String having, String orderBy, String limit)
[...]
Returns
A Cursor object, which is positioned before the first entry.
So first you have step c into the result set and you can use moveToFirst for that:
c.moveToFirst();
Now you need to extract the rowid from the row that the cursor is pointing at. But getColumnIndex is for mapping a column name to a position in the row:
Returns the zero-based index for the given column name, or -1 if the column doesn't exist.
You're getting a zero from getColumnIndex because your KEY_ROWID is the first column in your SELECT query.
I think you're looking for getLong if you want to extract a long from the Cursor's result set:
long rowid = c.getLong(c.getColumnIndex(KEY_ROWID));
If you know the structure of your query (which you do), you could skip the getColumnIndex call and just use the known index:
long rowid = c.getLong(0);
And if all you're doing is looking up the rowid, you can SELECT just KEY_ROWID:
String[] columns = new String[]{KEY_ROWID};
There's no need to pull things out of the database that you're ignoring.

Update table using rawQuery() method does not work

I tried the following SQLite query:
int idServizo = 150;
String whereClause = id_servizio+" = '"+idServizio+" ' ";
ContentValues cv = new ContentValues();
cv.put("sync", 1);
int r = dbManager.updateTable("myTable", cv, whereClause);
Where fields sync and id_servizio are both integer.
The method updateTable is:
public int updateTable(String table, ContentValues values, String whereClause){
int r = mDb.update(table, values, whereClause, null);
return r;
}
// mDb is SQLiteDatabase object
All this works good.
But if I try this with the rawQuery() method:
public Cursor RawQuery(String sqlQuery, String[] columns){
return mDb.rawQuery(sqlQuery, columns);
}
The table is not updated! even if no error occurs.
int idServizo = 150;
String updateQuery ="UPDATE myTable SET sync = 1 WHERE id_servizio = "+idServizio;
dbManager.RawQuery(updateQuery, null);
Why does this not work?

This is because when a rawQuery is executed cursor is returned. Without the call to cursor.moveToFirst() and cursor.close() the database won't get updated.
int idServizo = 150;
String updateQuery ="UPDATE myTable SET sync = 1 WHERE id_servizio = "+idServizio;
Cursor c= dbManager.rawQuery(updateQuery, null);
c.moveToFirst();
c.close();
I dont know the need to call moveToFirst() but this works fine and the database gets updated.

Problem solved.
http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html
Can't works because rawQuery runs the provided SQL and returns a Cursor over the result set.
If I want to return a table I have to use rawQuery, otherwise no!
Increase the value of a record in android/sqlite database

You should use db.execSQL() instead db.rawQuery().

Instead of doing this:
Cursor c= dbManager.RawQuery(updateQuery, null);
c.moveToFirst();
c.close();
You just need this:
dbManager.execSQL(updateQuery, null);

Posting answer because sometimes many people (like me) not reading comments.
Most popular answer is not correct but Yaqub Ahmad's comment is correct.
Answer from CommonsWare explained in this answer:
rawQuery() is for SQL statements that return a result set. Use
execSQL() for SQL statements, like INSERT, that do not return a result
set.
----------------------------------------------------------------------------
Documentation for execSQL:
public void execSQL (String sql)
Execute a single SQL statement that is NOT a SELECT or any other SQL statement that returns data.
Documentation for rawQuery:
public Cursor rawQuery (String sql,
String[] selectionArgs)
Runs the provided SQL and returns a Cursor over the result set.

Your update call formats the ID as string, while the rawQuery call formats is as number.
Assuming that the ID in the table indeed is a string, use:
String updateQuery = "UPDATE myTable SET sync = 1 WHERE id_servizio = '" + idServizio + "'";

Get last inserted value from sqlite database Android

I am trying to get the last inserted rowid from a sqlite database in Android. I have read a lot of posts about it, but can't get one to work.
This is my method:
public Cursor getLastId() {
return mDb.query(DATABASE_TABLE, new String[] {KEY_WID}, KEY_WID + "=" + MAX(_id), null, null, null, null, null);}
I have tried with MAX, but I must be using it wrong. Is there another way?

Well actually the SQLiteDatabase class has its own insert method which returns the id of the newly created row. I think this is the best way to get the new ID.
You can check its documentation here.
I hope this helps.

Use
SELECT last_insert_rowid();
to get the last inserted rowid.
If you are using AUTOINCREMENT keyword then
SELECT * from SQLITE_SEQUENCE;
will tell you the values for every table.

To get the last row from the table..
Cursor cursor = theDatabase.query(DATABASE_TABLE, columns,null, null, null, null, null);
cursor.moveToLast();

Use moveToLast() in Cursor interface.
From android.googlesource.com
/**
* Move the cursor to the last row.
*
* <p>This method will return false if the cursor is empty.
*
* #return whether the move succeeded.
*/
boolean moveToLast();
Simple example:
final static String TABLE_NAME = "table_name";
String name;
int id;
//....
Cursor cursor = db.rawQuery("SELECT * FROM " + TABLE_NAME, null);
if(cursor.moveToLast()){
//name = cursor.getString(column_index);//to get other values
id = cursor.getInt(0);//to get id, 0 is the column index
}
Or you can get the last row when insertion(Which is #GorgiRankovski have mentioned):
long row = 0;//to get last row
//.....
SQLiteDatabase db= this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(COLUMN_NAME, name);
row = db.insert(TABLE_NAME, null, contentValues);
//insert() returns the row ID of the newly inserted row, or -1 if an error occurred
Also their is a multiple ways you can do this using query:
One is expressed by #DiegoTorresMilano
SELECT MAX(id) FROM table_name. or to get all columns values SELECT * FROM table_name WHERE id = (SELECT MAX(id) FROM table_name).
If your PRiMARY KEY have sat to AUTOINCREMENT, you can SELECT vaules occording to max to min and limit the rows to 1 using SELECT id FROM table ORDER BY column DESC LIMIT 1
(If you want each and every value, use * instead of id)

If you want the last_insert_id just afert a insert you can use that :
public long insert(String table, String[] fields, String[] vals )
{
String nullColumnHack = null;
ContentValues values = new ContentValues();
for (int i = 0; i < fields.length; i++)
{
values.put(fields[i], vals[i]);
}
return myDataBase.insert(table, nullColumnHack, values);
}

The insert method returns the id of row just inserted or -1 if there was an error during insertion.
long id = db.insert("your insertion statement");
db is an instance of your SQLiteDatabase.

Try this:
public Cursor getLastId() {
return mDb.query(DATABASE_TABLE, new String[] { **MAX(id)** }, null, null, null, null, null, null);}

/**
* #return
*/
public long getLastInsertId() {
long index = 0;
SQLiteDatabase sdb = getReadableDatabase();
Cursor cursor = sdb.query(
"sqlite_sequence",
new String[]{"seq"},
"name = ?",
new String[]{TABLENAME},
null,
null,
null,
null
);
if (cursor.moveToFirst()) {
index = cursor.getLong(cursor.getColumnIndex("seq"));
}
cursor.close();
return index;
}

I use this
public int lastId(){
SQLiteDatabase db =
this.getReadableDatabase();
Cursor res = db.rawQuery( "select * from resep", null );
res.moveToLast();
return res.getInt(0);
}

In your DbHelper class,
public long getLastIdFromMyTable()
{
SQLiteDatabase db = this.getReadableDatabase();
SQLiteStatement st = db.compileStatement("SELECT last_insert_rowid() from " + MY_TABLE);
return st.simpleQueryForLong();
}
