java - how to write in the database with the same persist order -

-

I have this code that I am creating: 

  (int I = 0; I & lt; listofplusieurdrapage.size (); i ++) {continue (list Flalissepress.jet (I)); } I have two values ​​ 
  litsofplusieurdrapage => litsofplusieurdrapage.get (0) = 1 = & gt; Litsofplusieurdrapage.get (1) = 2   
 But when I check the database, I found them in this order:  
     
  •  2  
  •  1   
     And when I add the code to just one  system.out.println  I get good command  
     < Code> (int i = 0; i   
       
    •  1  
    •  2   
       Do you have an explanation of the problem? Adding  system.out.println  to your code Can I keep good order with my name?  
        public zero existence (object object) {em.persist (object);}    
       
       
       There is no command in the tables, for example and see other links. / P> 
       If you have  listofplusieurdrapage  If you need to order, you must specify the order, for example see.

You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
