how to edit/update jtable cell values into database

am trying to edit and update jtable cells as in my code below. my problem is that a single row when updated all the other rows get the same values. i mean only one row is updated and all other a duplicated. can any one help with a good approach. thanks
int count = Table_purchase.getRowCount();
int col = Table_purchase.getColumnCount();
String pod_id[] = new String[count];
String po_id[] = new String[count];
String order_qty[] = new String[count];
String item_id[] = new String[count];
String unit_price[] = new String[count];
String recived_qty[] = new String[count];
String rejected_qty[] = new String[count];
for (int i = 0; i < count; i++) {
po_id[i] = Table_purchase.getValueAt(i,0).toString();
pod_id[i] = Table_purchase.getValueAt(i,1).toString();
order_qty[i] = Table_purchase.getValueAt(i,2).toString();
item_id[i] = Table_purchase.getValueAt(i,3).toString();
unit_price[i] = Table_purchase.getValueAt(i,4).toString();
recived_qty[i] = Table_purchase.getValueAt(i, 5).toString();
rejected_qty[i] = Table_purchase.getValueAt(i,6).toString();
try {
String sql = "update purchase.purchase_detail set pod_id='" + pod_id[i] + "',order_qty='" + order_qty[i] + "',item_id='" + item_id[i] + "', unit_price='" + unit_price[i] + "', recived_qty='" + recived_qty[i] + "',rejected_qty='" + rejected_qty[i] + "'where po_id= '" + po_id[i] + "'";
pst = conn.prepareStatement(sql);
pst.execute();
JOptionPane.showMessageDialog(null, "updated");
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e);
}
}

Your sql statement does not contain a where-clause, hence all rows in the database table are updated for each iteration of the swing-table-rows, and in the end, all the database-rows will have the values from the last swing-table-row.
(And, use pst.setParameter (http://docs.oracle.com/javase/tutorial/jdbc/basics/prepared.html) and do not mix sql into gui-code.)

I recommend checking out the Java documentation, it provides a really good reference to start with. The .split method uses a regex to split up a string based on a delimiter.
String[] tokens = myString.split("0102\\*\\*");

For now I suspect that you forgot to escape * in split regex.
Try maybe
String[] resutl = yourString.split("0102\\*\\*");
In case you want * to represent any character then use . instead of *
String[] resutl = yourString.split("0102..");
In case you want * to represent any digit use \\d instead
String[] resutl = yourString.split("0102\\d\\d");

String string = "blabla0102**dada";
String[] parts = string.split("0102\\*\\*");
String part1 = parts[0]; // blabla
String part2 = parts[1]; // dada
Here we have a String: "blabla0102**dada", we call it string. Every String object has a method split(), using this we can split a string on anything we desire.

Do you mean literally split by "0102**"? Couldn't you use regex for that?
String[] tokens = "My text 0102** hello!".split("0102\\*\\*");
System.out.println(tokens[0]);
System.out.println(tokens[1]);

Android - How to retrieve contacts list as in native app?

I'm looking to export the contacts that are stored in the native database.
I'm having trouble retrieving contacts from native database.
Here is the query I would like to use :
Get all the contacts that have at least a phone number or an email.
Here is the query I am using :
String dataWhere = ContactsContract.Data.MIMETYPE + "=? OR " + ContactsContract.Data.MIMETYPE + "=?";
String[] dataWhereValues = new String[]{ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE};
String[] dataProjection = new String[]{ContactsContract.Data.CONTACT_ID, ContactsContract.Data.LOOKUP_KEY, ContactsContract.Data.DISPLAY_NAME_PRIMARY, ContactsContract.Data.STARRED, ContactsContract.Data.MIMETYPE, ContactsContract.Data.DATA1, ContactsContract.Data.DATA2, ContactsContract.Data.DATA_VERSION};
Cursor data = getContentResolver().query(ContactsContract.Data.CONTENT_URI, dataProjection, dataWhere, dataWhereValues, ContactsContract.Data.CONTACT_ID);
But this query gives me lots of weird contacts, and some of my contacts are also missing...
Can anyone help me please ?

this may help you for getting phone numbers and display names...
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
// importing phone contacts
while (phones.moveToNext())
{
listMobileNo.add(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
listName.add(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
}
phones.close();

Here is the query I ended up with
String where = ContactsContract.Data.MIMETYPE + "=? OR " + ContactsContract.Data.MIMETYPE + "=?";
String[] whereValues = new String[]{ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE, ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE};
String[] dataProjection = new String[]{ContactsContract.Data.CONTACT_ID, ContactsContract.Data.LOOKUP_KEY, ContactsContract.Data.DISPLAY_NAME_PRIMARY, ContactsContract.Data.STARRED, ContactsContract.Data.MIMETYPE, ContactsContract.Data.DATA1, ContactsContract.Data.DATA2, ContactsContract.Data.DATA_VERSION};
Cursor cursor = context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, dataProjection, dataWhere, dataWhereValues, ContactsContract.Data.CONTACT_ID + " ASC");
int cidIndex = cursor.getColumnIndexOrThrow(ContactsContract.Data.CONTACT_ID);
int nameIndex = cursor.getColumnIndexOrThrow(ContactsContract.Data.DISPLAY_NAME_PRIMARY);
int starredIndex = cursor.getColumnIndexOrThrow(ContactsContract.Data.STARRED);
int typeIndex = cursor.getColumnIndexOrThrow(ContactsContract.Data.MIMETYPE);
int data1Index = cursor.getColumnIndexOrThrow(ContactsContract.Data.DATA1);
int data2Index = cursor.getColumnIndexOrThrow(ContactsContract.Data.DATA2);
int lookupKeyIndex = cursor.getColumnIndexOrThrow(ContactsContract.Data.LOOKUP_KEY);
int versionIndex = cursor.getColumnIndexOrThrow(ContactsContract.Data.DATA_VERSION);
boolean hasData = cursor.moveToNext();
while (hasData){
contactId = cursor.getLong(cidIndex);
nativeLookupKey = cursor.getString(lookupKeyIndex);
fullName = cursor.getString(nameIndex);
starred = cursor.getInt(starredIndex);
version = cursor.getLong(versionIndex);
while (currentContactId <= contactId && hasData) {
if (currentContactId == contactId) {
String type = cursor.getString(typeIndex);
if (type.equals(ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)) {
String email = cursor.getString(data1Index);
} else if (type.equals(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)) {
String number = cursor.getString(data1Index);
}
}
hasData = cursor.moveToNext();
if (hasData) {
currentContactId = cursor.getLong(cidIndex);
}
}
}

I have a basic database up for my app. Im trying to sum the iScore and store it but am not sure how

I'm trying to sum the iScore and display and maybe store it but am not sure how.
public String getData() {
String[] columns = new String[] { KEY_ROWID, KEY_SCORE, KEY_PUTTS };
Cursor c = csDatabase.query(DATABASE_TABLE, columns, null, null, null, null, null);
String result = "";
int iRow = c.getColumnIndex(KEY_ROWID);
int iScore = c.getColumnIndex(KEY_SCORE);
int iPutts = c.getColumnIndex(KEY_PUTTS);
for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()) {
result = result + c.getString(iRow) + " " + c.getString(iScore) + " " +
c.getString(iPutts) + "\n";
}
return result;
}

You're trying to 'sum' strings. + is the concatenate operator. Convert them to numbers and then add them together.

I am not sure what you want to do, but:
if you want to sum the numbers in KEY_SCORE, then
result = result + c.getString(iScore);
or
result = result + c.getString(1);
OR:
public static final String KEY_ROWID = "_id";
public static final String KEY_SCORE = "pscore";
public static final String KEY_PUTTS = "pputts";
then in the getData method:
Cursor c = ourDatabase.query(DATABASE_TABLE, new String[] { "_id","sum(pscore)","pputts" },
null,null,null , null, null);

This is making my program freeze

every time this starts my program freezes, and I can't figure out why.
It doesn't give any errors, it just freezes.
Is it possible I've created some kind of endless loop?
public static String[] DataVoorList(int coureur) throws SQLException{
ArrayList datalijst = new ArrayList();
String query = ""
+ "SELECT rd_datum, rd_locatie, rd_code "
+ "FROM racedag WHERE rd_code in( "
+ "SELECT i_rd_code "
+ "FROM inschrijvingen "
+ "WHERE i_c_nummer = " + coureur + ");";
ResultSet rs = Database.executeSelectQuery(query);
int i=0;
while (rs.next()){
String datum = rs.getString("rd_datum");
String locatie = rs.getString("rd_locatie");
String totaal = "" + datum + " - " + locatie;
datalijst.add(i, totaal);
i++;
int codeInt = rs.getInt("rd_code");
String code = ""+codeInt;
datalijst.add(i, code);
i++;
}
return Race.StringDataVoorList(datalijst);
}
public static String[] StringDataVoorList(ArrayList invoer){
int lengte = invoer.size();
String[] uitvoer = new String[lengte];
int i =0;
while (i < uitvoer.length){
uitvoer[i] = ""+invoer.get(i);
}
return uitvoer;
}
EDIT: I've solved the increment. However, it still freezes.
EDIT 2: I think I have located the problem (but I can be wrong)
public static String[] DataVoorList(int coureur) throws SQLException {
System.out.println("stap 1");
ArrayList datalijst = new ArrayList();
String query = ""
+ "SELECT rd_datum, rd_locatie, rd_code "
+ "FROM racedag WHERE rd_code in( "
+ "SELECT i_rd_code "
+ "FROM Inschrijvingen "
+ "WHERE i_c_nummer = " + coureur + ");";
ResultSet rs = Database.executeSelectQuery(query);
System.out.println("stap 2");
int i = 0;
while (rs.next()) {
String datum = rs.getString("rd_datum");
String locatie = rs.getString("rd_locatie");
String totaal = "" + datum + " - " + locatie;
datalijst.add(i, totaal);
System.out.println("stap 3");
i++;
int codeInt = rs.getInt("rd_code");
String code = "" + codeInt;
datalijst.add(i, code);
i++;
System.out.println("stap 4");
}
return Race.StringDataVoorList(datalijst);
(I've changed the while loop to a for loop)
public static String[] StringDataVoorList(ArrayList invoer) {
int lengte = invoer.size();
String[] uitvoer = new String[lengte];
for (int i = 0; i < uitvoer.length; i++) {
uitvoer[i] = "" + invoer.get(i);
}
return uitvoer;
}
}
this is being called from here:
public MijnRacedagenScherm() throws SQLException{
initComponents();
int gebruiker = Inloggen.getNummer();
String[] DataVoorList = Race.DataVoorList(2);
int lengte = DataVoorList.length;
System.out.println("resultaat is " + DataVoorList[0]);
int i = 0;
while (i < lengte) {
ListRacedagenCoureur.setListData(DataVoorList);
i = i + 2;
}
System.out.println("lengte is " + lengte);
}
This is a new screen, but in the previous screen I get a unreported SQL exception over this:
private void ButtonZienRacedagActionPerformed(java.awt.event.ActionEvent evt) {
new MijnRacedagenScherm().setVisible(true);
}

Well, um... In this section:
while (i < uitvoer.length){
uitvoer[i] = ""+invoer.get(i);
}
Where is i incremented?

Indeed it is, this
int i =0;
while (i < uitvoer.length){
uitvoer[i] = ""+invoer.get(i);
}
You never increment i.

As stated problem is in your while loop.
for loop is more suitable for iterating over indexed data type
for (int i = 0; i < uitvoer.length; i++) {
uitvoer[i] = ""+invoer.get(i);
}

How many rows are you processing? The way you append strings is quite slow, maybe it's not freezing anymore but just taking a long time to complete.
