  • How to get multiple counts with one SQL query?

    - by Crobzilla
    I am wondering how to write this query. I know this actual syntax is bogus, but it will help you understand what I am wanting. I need it in this format, because it is part of a much bigger query. SELECT distributor_id, COUNT(*) AS TOTAL, COUNT(*) WHERE level = 'exec', COUNT(*) WHERE level = 'personal' I need this all returned in one query. Also, it need to be in one row, so the following won't work: 'SELECT distributor_id, COUNT(*) GROUP BY distributor_id'

  • How does one use TrafficStats.incrementOperationCount()?

    - by Dheeraj
    The documentation for TrafficStats.incrementOperationCount() says: Increment count of network operations performed under the given accounting tag. This can be used to derive bytes-per-operation. I want to find the total number of bytes transferred during a particular network operation. Since this API claims to help in deriving bytes-per-operation, can someone help me understand how to use it?

  • Maximal Length of List to Shuffle with Python random.shuffle?

    - by Henrik
    I have a list which I shuffle with the Python built in shuffle function (random.shuffle) However, the Python reference states: Note that for even rather small len(x), the total number of permutations of x is larger than the period of most random number generators; this implies that most permutations of a long sequence can never be generated. Now, I wonder what this "rather small len(x)" means. 100, 1000, 10000,... Can anybody clarify? Thanks!

  • Need help with basic optimization problem

    - by ??iu
    I know little of optimization problems, so hopefully this will be didactic for me: rotors = [1, 2, 3, 4...] widgets = ['a', 'b', 'c', 'd' ...] assert len(rotors) == len(widgets) part_values = [ (1, 'a', 34), (1, 'b', 26), (1, 'c', 11), (1, 'd', 8), (2, 'a', 5), (2, 'b', 17), .... ] Given a fixed number of widgets and a fixed number of rotors, how can you get a series of widget-rotor pairs that maximizes the total value where each widget and rotor can only be used once?

    - by Sai Sasdhar
    Is there any CSS property to deal window resolution. I created a HTML page taking total resolution width as 1424px.When I open it on different resolution I see a scroll bar & resolution of HTML does not adjust automatically. I don't want the scrollbar to be seen in maximized size of the page. Is it possible without using javascript.At the same time how to increase the resolution when itself is created in lower res.

  • ms access negative page numbers

    - by FrustratedWithFormsDesigner
    I have an access report that generates 36505 pages (un filtered, and about half of each page is taken up by group headers and page headers) , though the footer at the bottom of the report page says "36505 of -29031". This looks like an overflow problem maybe, though I'm confused how it got the current page number of the last page OK, but failed to get total page count. Has anyone dealt with this before?

    Hello gurus, I have a desktop application sending/receiving messages (not files) to/from a WCF service. How do I intercept the total size of the message to be transferred and receive feedback (number of bytes transferred) during the transmission so a progress bar maybe displayed to the desktop app user? How many approaches are there? What is the best one given my application scenario? Any comments or suggestions will be greatly appreciated, Cullen

  • Recreating the Apple Store's summary that moves with the page scrolling

    - by Darryl Hein
    I'm looking to create something like what Apple has on their online store for displaying the summary of your computer and total as seen here. I'm guessing this is JavaScript, but it'd be even cooler if it could be done in CSS. Basically I'd like something scrolls with the page like position:fixed, but I don't want it to start moving until the user has scroll past a certain position. I'm using jQuery, so a jQuery plugin would be perfect as well.

    - by user330239
    Hi guys, i wanted to make a double border but with no space in between and the double border should be of different color. I tried using image instead but i thought css could probably perform this job for me, i searched the net but hardly find anything close. What i wanted is total of 2px dotted border with top color of #a4a4a4 and bottom color of #474747. Any idea how i can do this instead of creating 2 divs?

  • pagination - 10 pages per page

    - by arthur
    I have a pagination script that displays a list of all pages like so: prev [1][2][3][4][5][6][7][8][9][10][11][12][13][14] next But I would like to only show ten of the numbers at a time: prev [3][4][5][6][7][8][9][10][11][12] next How can I accomplish this? Here is my code so far: <?php /* Set current, prev and next page */ $page = (!isset($_GET['page']))? 1 : $_GET['page']; $prev = ($page - 1); $next = ($page + 1); /* Max results per page */ $max_results = 2; /* Calculate the offset */ $from = (($page * $max_results) - $max_results); /* Query the db for total results. You need to edit the sql to fit your needs */ $result = mysql_query("select title from topics"); $total_results = mysql_num_rows($result); $total_pages = ceil($total_results / $max_results); $pagination = ''; /* Create a PREV link if there is one */ if($page > 1) { $pagination .= '< a hr_ef="?page='.$prev.'">Previous</a> '; } /* Loop through the total pages */ for($i = 1; $i <= $total_pages; $i++) { if(($page) == $i) { $pagination .= $i; } else { $pagination .= '< a hr_ef="index.php?page='.$i.'">'.$i.'</a>'; } } /* Print NEXT link if there is one */ if($page < $total_pages) { $pagination .= '< a hr_ef="?page='.$next.'"> Next</a>'; } /* Now we have our pagination links in a variable($pagination) ready to print to the page. I pu it in a variable because you may want to show them at the top and bottom of the page */ /* Below is how you query the db for ONLY the results for the current page */ $result=mysql_query("select * from topics LIMIT $from, $max_results "); while ($i = mysql_fetch_array($result)) { echo $i['title'].'<br />'; } echo $pagination; ?>

  • Using tinybutstrong templating system, how do I have a (secondary) mysql query (sub-block), inside a

    - by desbest
    This is the code that works well. $TBS->MergeBlock("items",$conn,"SELECT * FROM items WHERE categoryid = $getcategory"); and it has a good job of looping the items with no problem. <tr id="itemid_[items.id;block=tr]"> <td height="30"> <!-- <img src="move.png" align="left" style="margin-right: 8px;"> --> <div class="lowlight">[items.title] </div> </td> <td height="30"> <div class="editable" itemid="$item[id]">[items.quantity]</div> </td> <td height="30"> <!-- <img src="pencil.png" id="edititem"width="24" height="24"> --> &nbsp; &nbsp; &nbsp; &nbsp;<img src="icons/folder.png" id="category_[items.categoryid]";" class="changecategory" categoryid="[items.categoryid]" itemid="[items.id]" itemtitle="[items.title]" title="Change category" width="24" height="24"> &nbsp; &nbsp; &nbsp; &nbsp; <a href="index.php?category=[var.getcategory]&deleteitem=[items.id]" title="Delete item" onclick="return confirm('Are you sure you want to delete [items.title]?')"><img src="icons/trash.png" id="deleteitem" width="24" height="24"></a> </td> </tr> This is where the problem lies. In the table row I would like a secondary mysql merge block based on the id column that the primary (items) mysql table has. This means that ideally I would love to do this. $TBS->MergeBlock("fields",$conn,"SELECT * FROM items WHERE categoryid = [items.id]"); So then when I used [fields.value;block=div] inside the table row, it would pick up the a row from the fields table based on the primary mysql query. It would recognise what the id is for the merged block and perform a mysql query based on a variable that that block has. So that's what I would like to do and that's what I call a secondary mysql merge block. This is what I attempted by using the sub-blocks example and modifying it. index.html <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>TinyButStrong - Examples - subblocks</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <link href="tbs_us_examples_0styles.css" rel="stylesheet" type="text/css"> <style type="text/css"> <!-- .border02 { border: 2px solid #39C; } .border03 { border: 2px solid #396; } --> </style> </head> <body> <table width="400" align="center" cellpadding="5" cellspacing="0" style="border-collapse:collapse;"> <tr> <td class="border02"><strong>Item name:</strong> [item.title;block=tr] , <strong>Item quantity:</strong> [item.quantity]<br> <table border="1" align="center" cellpadding="2" cellspacing="0"> <tr bgcolor="#CACACA"> <td width="30"><u>Position</u></td> <td width="150"><u>Attribute</u></td> <td width="50"><u>Value</u></td> <td width="100"><div align="center"><u>Date Number</u></div></td> </tr> <tr bgcolor="#F0F0F0"> <td>[field.#]</td> <td>[field.attribute;block=tr;p1=[item.id]] <br><b>[item.id]</b> </td> <td><div align="right">[field.value]</div></td> <td><div align="center">[field.datenumber;frm='mm-dd-yyyy']</div></td> </tr> </table> </td> </tr> </table> </body> </html> index.php <?php require_once('../stockman-v3/tbs_class.php'); require_once('../stockman-v3/config.php'); // Create data $TeamList[0] = array('team'=>'Eagle' ,'total'=>'458'); //{ $TeamList[0]['matches'][] = array('town'=>'London','score'=>'253','date'=>'1999-11-30'); $TeamList[0]['matches'][] = array('town'=>'Paris' ,'score'=>'145','date'=>'2002-07-24'); $TeamList[1] = array('team'=>'Goonies','total'=>'281'); $TeamList[1]['matches'][] = array('town'=>'New-York','score'=>'365','date'=>'2001-12-25'); $TeamList[1]['matches'][] = array('town'=>'Madrid' ,'score'=>'521','date'=>'2004-01-14'); // } $TeamList[2] = array('team'=>'MIB' ,'total'=>'615'); // { $TeamList[2]['matches'][] = array('town'=>'Dallas' ,'score'=>'362','date'=>'2001-01-02'); $TeamList[2]['matches'][] = array('town'=>'Lyon' ,'score'=>'321','date'=>'2002-11-17'); $TeamList[2]['matches'][] = array('town'=>'Washington','score'=>'245','date'=>'2003-08-24'); // } $TBS = new clsTinyButStrong; $TBS->LoadTemplate('index3.html'); // Automatic subblock $TBS->MergeBlock("item",$conn,"SELECT * FROM items"); $TBS->MergeBlock("field",$conn,"SELECT * FROM fields WHERE itemid='[%p1%]' "); $TBS->MergeBlock('teamKEY',$TeamList); // Subblock with a dynamic query //$TBS->MergeBlock('match','array','TeamList[%p1%][matches]'); $TBS->MergeBlock("match",$conn,"SELECT * FROM fields WHERE id='[%p1%]' "); $TBS->Show(); ?> please note what i am trying to do If I was to change $TBS->MergeBlock("field",$conn,"SELECT * FROM fields WHERE itemid='[%p1%]' "); to... $TBS->MergeBlock("field",$conn,"SELECT * FROM fields"); It would show all the items.

    - by spacemonkey
    Hi, I need to sort query results by the output of some function which takes "score" and couple other fields as an input (50% of the total score comes from similarity score and 50% comes from document's popularity). Is there a way to do this without having to install "Sort by Function" patch? Thanks!

  • Zend_Paginator / Doctrine 2

    - by Kevin
    I'm using Doctrine 2 with my Zend Framework application and a typical query result could yield a million (or more) search results. I want to use Zend_Paginator in line with this result set. However, I don't want to return all the results as an array and use the Array adapter as this would be inefficient, instead I would like to supply the paginator the total amount of rows then and array of results based on limit/offset amounts. Is this doable using the Array adapter or would I need to create my own pagination adapter?

  • Haskell Add Function Return to List Until Certain Length

    - by kienjakenobi
    I want to write a function which takes a list and constructs a subset of that list of a certain length based on the output of a function. If I were simply interested in the first 50 elements of the sorted list xs, then I would use fst (splitAt 50 (sort xs)). However, the problem is that elements in my list rely on other elements in the same list. If I choose element p, then I MUST also choose elements q and r, even if they are not in the first 50 elements of my list. I am using a function finderFunc which takes an element a from the list xs and returns a list with the element a and all of its required elements. finderFunc works fine. Now, the challenge is to write a function which builds a list whose total length is 50 based on multiple outputs of finderFunc. Here is my attempt at this: finish :: [a] -> [a] -> [a] --This is the base case, which adds nothing to the final list finish [] fs = [] --The function is recursive, so the fs variable is necessary so that finish -- can forward the incomplete list to itself. finish ps fs -- If the final list fs is too small, add elements to it | length fs < 50 && length (fs ++ newrs) <= 50 = fs ++ finish newps newrs -- If the length is met, then add nothing to the list and quit | length fs >= 50 = finish [] fs -- These guard statements are currently lacking, not the main problem | otherwise = finish [] fs where --Sort the candidate list sortedps = sort ps --(finderFunc a) returns a list of type [a] containing a and all the -- elements which are required to go with it. This is the interesting -- bit. rs is also a subset of the candidate list ps. rs = finderFunc (head sortedps) --Remove those elements which are already in the final list, because -- there can be overlap newrs = filter (`notElem` fs) rs --Remove the elements we will add to the list from the new list -- of candidates newps = filter (`notElem` rs) ps I realize that the above if statements will, in some cases, not give me a list of exactly 50 elements. This is not the main problem, right now. The problem is that my function finish does not work at all as I would expect it to. Not only does it produce duplicate elements in the output list, but it sometimes goes far above the total number of elements I want to have in the list. The way this is written, I usually call it with an empty list, such as: finish xs [], so that the list it builds on starts as an empty list.
