Hello,
I've been trying to make my first Android app.
I created a library project that cointain an activity called 'Reader':
public class Reader extends Activity {
private String ID;
public void setID(String id) {
ID = id;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_reader);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_reader, menu);
return true;
}
}
also i created a (test) project that contain another activity called 'MainActivity':
public class MainActivity extends Reader {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setID("bla_bla_bla");
}
}
when it comes to the GUI the inheritance is working well, i can see everything I placed in 'Reader' on 'MainActivity', but when it comes to using inherited methods such as 'setID(String)' i get a compilation error Eclipse Quote: The method setID(String) is undefined for the type MainActivity
How can it be?
thank you very much!!!

Have you tried using
super.setID("bla_bla_bla");

How do I add method for last_insert_rowid
I added a record to the table. As soon as it is entered I want to get the rowed that SQLite gave to it. How can I accomplish this?
|
|
|
|
|
You should be able to use last_insert_rowid for the last row id that was inserted for that connection. Basically, inside the same connection, issue a separate select command:
SELECT last_insert_rowid
|

Hi Pete,
I tried this and it wont let me compile. I don't know the correct syntax. There is not much out there for WP8 SQLite
string query = "select last_insert_rowid() as id from myTable";
using (var db = new SQLite.SQLiteConnection(System.IO.Path.Combine(ApplicationData.Current.LocalFolder.Path, "SM.db"), true))
{
SQLite.SQLiteCommand cmd = new SQLite.SQLiteCommand(db);
var result = cmd.ExecuteNonQuery();
}
|
|
|
|
|
No. Only select last_insert_rowid();. You don't need the rest. There's a reaaon I didn't include it in my answer there.
|
|
|
|
|
I tried that and I get this error
SQLite.SQLiteException: Misuse
|
|
|
|
|
I tried this also and the error is "Row"
SQLite.SQLiteCommand cmd = new SQLite.SQLiteCommand(db);
cmd.CommandText = query.ToString();
var result2 = cmd.ExecuteNonQuery();
|
|
|
|
|
If you're trying to retrieve the record, use ExecuteScalar, not ExecuteNonQuery.
|
|
|
|
|
Ok,
So what is the syntax for that?
cmd.ExecuteScalar< ? >;
Sorry, I just don't know SQLite
|
|
|
|
|
It should just be something like:
private int GetLastRowId(SQLLite.SQLLiteConnection connection)
{
SQLLite.SQLLiteCommand cmd = new (connection);
cmd.CommandText = "SELECT last_insert_rowid";
object rowId = cmd.ExecuteScalar();
return Convert.ToInt32(rowId);
}
|
|
|
|
|
|
|
Cursor cursor = getReadableDatabase().
rawQuery("select * from todo where _id = ?", new String[] { id });
|

I have a Windows Phone 8 App using SQLite (C#, XAML) I want to create records in my table in code. I tried an experiment by just placing a button on my window that executes a counter to create 10 records in my database. When I execute it, I get no errors, but the records are not in the database. Could you tell me what I am doing wrong?
For instance, with my DataModel:
class Test
{
[SQLite.AutoIncrement, SQLite.PrimaryKey]
public int TestID { get; set; }
public int MyCounter { get; set; }
}
And my View Model
public class TestViewModel : ViewModelBase
{
#region Properties
private int testid = 0;
public int testid
{
get
{ return testid; }
set
{
if (testid == value)
{ return; }
testid = value;
RaisePropertyChanged("TestID");
}
}
private int mycounter = 0;
public int MyCounter
{
get
{ return mycounter ; }
set
{
if (mycounter == value)
{ return; }
mycounter = value;
RaisePropertyChanged("MyCounter");
}
}
#endregion
public string SaveRecord(TestViewModel _vm)
{ string result = string.Empty;
using(var db = new SQLite.SQLiteConnection(app.DBPath))
{
string change = string.Empty;
try
{
var er = (db.Table().Where(
c => c.TestID == _vm.TestID)).SingleOrDefault();
if (er != null)
{
er.MyCounter = _vm.MyCounter;
int success = db.Update(er);
}
else
{
int success = db.Insert(new Test()
{
TestID = _vm.TestID,
MyCounter = _vm.MyCounter,
});
}
result = "Success";
}
catch (Exception ex)
{
StringBuilder erMessage = new StringBuilder();
erMessage.Append("This record was not saved.");
erMessage.AppendLine();
erMessage.Append(ex);
result = "This record was not saved.";
}
}
return result;
}
}
So in my Window I just tried a test
public partial class MyWindow : PhoneApplicationPage
{
RoundShotTest mytest = null;
…..
….
}
private void buttonTryMe_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
For(int x = 0; x < 10; x++)
{
mytest = new TestViewModel();
mytest.MyCounter = x;
string result = mytest.SaveRecord(mytest);
}
What am I doing wrong here. I get no error, but when I take a look in the database, the records have not been written?
|

Where do you look in the database? In your debug directory, or in the directory it was originally in? When you develop an application in Visual Studio, the Compile Options (in the Properties page for a particular file) tell you whether or not the file is going to be copied to a different location. Immediately after your loop, select a count of the records to see how many there are.

Hi Pete,
The db file itself is marked Build Action is set as Content, and Copy to Output Directory is set as Copy if Newer.
In my App.xaml I have:
public partial class App : Application
{
public static IsolatedStorageSettings myappsettings = IsolatedStorageSettings.ApplicationSettings;
private string dbName = "SM.db";
public const string ConnectionString = @"isostore:/SM.db";
private string dBPath = string.Empty;
public static SQLiteAsyncConnection Connection { get; set; }
public string DBPath
{
get
{ return dBPath; }
set
{
if (dBPath == value)
{ return; }
dBPath = value;
}
}
Whats even more weird is that I did this on another app, without the exception of the counter, and it worked. I'm lost?
