while-loop

问题 I have table with 3 primary keys : CODE_TARIF, UNITE , and MODE_LIV . I write a stored procedure to copy and paste but with different MODE_LIV . ex: if I already have 2 rows in table T_TARIF with MODE_LIV = 2, when I run this stored procedure with input MODE_LIV =3 , I will have 4 rows . ALTER PROCEDURE [dbo].[Copy_Tarif] -- Add the parameters for the stored procedure here @MODE_LIV int AS BEGIN DECLARE @CODE_TARIF varchar(15) DECLARE @ZONE int DECLARE @UNITE int DECLARE @LIBELLE varchar(30)

问题 Here is my loop code (This is the only code relating to my loop): while(true) { try { Thread.sleep(20); System.out.println("1"); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } When I launch the applet, it white screens and I cannot close it unless I press the "Terminate" button in eclipse. 回答1: You're blocking the UI Thread with an infinite while loop. You don't say whether you're using an AWT or Swing applet, either way the result will be the

问题 Both while MyFunction(1, 2, 3) > 0 do begin Temp := MyFunction(1, 2, 3); ShowMessage(IntToStr(Temp)); end; and Temp := MyFunction(1, 2, 3); while Temp > 0 do begin ShowMessage(IntToStr(Temp)); Temp := MyFunction(1, 2, 3); end; violate the DRY principle because there are two calls to MyFunction when only one is necessary. 回答1: Easy, function dotemp(a,b,c:integer;var value : integer):boolean; begin value:a*b+c; result:=value>0; end; begin while dotemp(a,b,c,temp) do begin Operateontemp(temp);

问题 it is incredible how the knowledge of something so basic can be buried in a so hard to find place. I have spent close to a month googling for an answer--watching videos, reading documents, books, etc--of how to stop a while loop to get input from an user using Tkinter. My code below is looping twice and leaving the loop before I am able to provide an input!!! Anyway, theory is appreciated, but a sample code will be of greater help. Thank you very, very much indeed. # Python 3.5.1 from tkinter

问题 Using a while loop, I'm prompting the user to enter 5 different numbers and trying to create a total of those numbers. How would I be able to create that total? This is my code so far count = 1 while count < 5: count += 1 int(input("Enter a value: ")) 回答1: count = 1 total = 0 while count < 5: count += 1 total += int(input("Enter a value: ")) print (total) 来源： https://stackoverflow.com/questions/40026355/python-adding-values-in-a-while-loop

问题 I'm stuck on something small, hope you can help me.. I need all phone numbers (thats a column in table 'leerlingen') in one here, with comma's separated, so I can insert that here in another script and it shows all phone numbers, like this: 0612345637,061231823,061231723 Code: $result = mysql_query("SELECT * FROM leerlingen WHERE klas_id='$aan_klas'"); while($row = mysql_fetch_array($result)) { $variabele = $row['leerling_nummer'] . ","; echo "$variabele"; } But, when I echo $variabele

问题 Trying to work on a clients site and I am having a bit of difficulty. When I have no entries in the database, it catches at if(!row) and displays the message. This part works fine. My issue is when I have entries in the db, they do not display. I know the while loop works because I have several pages running a similar loop. In fact, this loop was copied from another page that displays this entry's information on a public page. I know this site is mainly for questions, but I think I just need
