android - Find objects in SQL database that match a value in a certain column -


मेरे पास ऐसा डेटाबेस है: 

  id | स्तर | पाठ 1 | 1 | ब्लाह 2 | 1 | Blah2 3 | 1 | Blah3 4 | 2 | नमस्ते 5 | 2 | नमस्कार

मेरे पास एक ऐसा तरीका है, जहां मैं स्तर 1 में मौजूद वस्तुओं की एक सूची वापस करना चाहता हूं 

  कर्सर कर्सर = db.query (TABLE_NAME, रिक्त, रिक्त, रिक्त, ????, रिक्त, ऑर्डर बीवाई); If (cursor.moveToFirst ()) {करना {पाठ टी = नया पाठ (); t.setId (String.valueOf (cursor.getString (0))); t.setLevel (String.valueOf (cursor.getString (1))); t.setText (cursor.getString (2)); list.add (टी); } जबकि (कर्सर.मॉवटेओनेक्स्ट ()); } वापसी सूची;

मैं केवल उन वस्तुओं को अलग करने के लिए क्वेरी पैरामीटर में क्या डालूं जो स्तर 1 में हैं ?? 

  कर्सर कर्सर = db.query (TABLE_NAME, रिक्त," स्तर = 1 ", रिक्त, रिक्त, रिक्त, ऑर्डर बीवाई);

आपको WHERE शर्त का उपयोग करके इसे फ़िल्टर करना होगा!

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment.
