  • MySQL Select statement Where table1.id != table2.id

    - by Michael
    I have a table of data which has posts, then I have a separate table of data which has deleted posts. What happens when a post is deleted is that it's ID get's added to the deleted table rather than removing the post entry. What is a clean efficient way of selecting all the posts from the posts table without selecting the ones that have their ID in the deleted table

  • VBA: Difference in two ways of declaring a new object? (Trying to understand why my solution works)

    - by Matt
    I was creating a new object within a loop, and adding that object to a collection; but when I read back the collection after, it was always filled entirely with the last object I had added. I've come up with two ways around this, but I simply do not understand why my initial implementation was wrong. Original: Dim oItem As Variant Dim sOutput As String Dim i As Integer Dim oCollection As New Collection For i = 0 To 10 Dim oMatch As New clsMatch oMatch.setLineNumber i oCollection.Add oMatch Next For Each oItem In oCollection sOutput = sOutput & "[" & oItem.lineNumber & "]" Next MsgBox sOutput This resulted in every lineNumber being 10; I was obviously not creating new objects, but instead using the same one each time through the loop, despite the declaration being inside of the loop. So, I added Set oMatch = Nothing immediately before the Next line, and this fixed the problem, it was now 0 to 10. So if the old object was explicitly destroyed, then it was willing to create a new one? I would have thought the next iteration through the loop would cause anything declared within the loop do be destroyed due to scope? Curious, I tried another way of declaring a new object: Dim oMatch As clsMatch: Set oMatch = New clsMatch. This, too, results in 0 to 10. Can anyone explain to me why the first implementation was wrong?

  • T-SQL GO Statement

    - by coffeeaddict
    I have read and read over MSDN, etc. Ok, so it signals the end of a batch. What defines a batch? I don't see why I need go when I'm pasting in a bunch of scripts to be run all at the same time. I've never understood GO. Can anyone explain this better and when I need to use it (after how many or what type of transactions)?

  • Weird syntax for extending jQuery

    - by cantabilesoftware
    I recently saw this code on another post ( http://stackoverflow.com/questions/499126/jquery-set-cursor-position-in-text-area ) new function($) { $.fn.setCursorPosition = function(pos) { // function body omitted, not relevant to question } } (jQuery); After too long trying to understand what it was doing I finally figured out that it's just creating a new function with a parameter $ and then invoking it with jQuery as the parameter value. So actually, it's just doing this: jQuery.fn.setCursorPosition = function(pos) { // function body omitted, not relevant to question } What's the reason for the original, more confusing version?

  • Generating my own SQL Server SSL Certificate

    - by Haoest
    I hear it's possible to make myself a test certificate with MakeCert from Windows SDK, but the beast is 1.5 GB, which I feel reluctant to download for a half-megabyte program. I do, however, have IIS Resource kit with me, which has selfssl to generate certificate for IIS. Will that work for SQL Server? Is there a more convenient way of generating myself an SSL certificate for SQL Server use? I even tried using CREATE CERTIFICATE with TSQL within SQL Server and then have it BACKUP into a file, but with no success. I must have confused the concept of certificate fundamentally. Any advice?

  • Initialisation of Objects Syntax question

    - by Brock Woolf
    When I initialise a struct in C (Node is the struct): struct Node { /* Non-Relevant code */ }; This works: Node *rootNode = new Node(); but so does this: Node *rootNode = new Node; Is there a difference, and what is the difference between using () or not using the brackets? Just off memory, I think the same applies above for C++ object initialisations. What is happening here?

  • Pascal's repeat... until vs. C's do... while

    - by Bob
    In C there is a do while loop and pascal's (almost) equivalent is the repeat until loop, but there is a small difference between the two, while both structures will iterate at least once and check whether they need to do the loop again only in the end, in pascal you write the condition that need to met to terminate the loop (REPEAT UNTIL something) in C you write the condition that need to be met to continue the loop (DO WHILE something). Is there a reason why there is this difference or is it just an arbitrary decision?

  • User control loosing its contents when loaded programatically

    - by Phil
    I have a usercontrol which contains 2 repeaters and the code to populate them with data. If i manually insert this into the page then it works correctly, the repeaters populate etc. If I load it programatically using this method; 1) add class name to user control ClassName="ContentModule" 2) reference this in the default.aspx <%@ Reference Control="~/modules/content.ascx" %> 3) Add the code to my codebehind page_load to do the loading; Private loadmodule As ASP.ContentModule Try If themodule = "content" Then loadmodule = CType(LoadControl("~\Modules\Content.ascx"), ASP.ContentModule) Modulecontainer.Controls.Add(loadmodule) End If Catch ex As Exception Response.Write(ex.ToString & "<br />") End Try Nothing from within the usercontrol is loaded to the page. Although if I add some static text i.e "TEST" to the top of the usercontrol this is displayed ok on the default.aspx page. This makes me think that the control is loaded ok, but there is something in the way I have loaded it that is causing the contents to not properly execute. Very frustrating this one! Any help greatly appreciated!

  • Separating positive values from 'zero' values in an XSLT for-each statement

    - by danielle
    I am traversing an XML file (that contains multiple tables) using XSLT. Part of the job of the page is to get the title of each table, and present that title with along with the number of items that table contains (i.e. "Problems (5)"). I am able to get the number of items, but I now need to separate the sections with 0 (zero) items in them, and put them at the bottom of the list of table titles. I'm having trouble with this because the other items with positive numbers need to be left in their original order/not sorted. Here is the code for the list of titles: <ul> <xsl:for-each select="n1:component/n1:structuredBody/n1:component/n1:section/n1:title"> <li style="list-style-type:none;"> <div style = "padding:3px"><a href="#{generate-id(.)}"> <xsl:variable name ="count" select ="count(../n1:entry)"/> <xsl:choose> <xsl:when test = "$count != 0"> <xsl:value-of select="."/> (<xsl:value-of select="$count"/>) </xsl:when> <xsl:otherwise> <div id = "zero"><xsl:value-of select="."/> (<xsl:value-of select="$count"/>)</div> </xsl:otherwise> </xsl:choose> </a> </div> </li> </xsl:for-each> </ul> Right now, the "zero" div just marks each link as gray. Any help regarding how to place the "zero" divs at the bottom of the list would be greatly appreciated. Thank you!

  • Simpler range finder?

    - by dotty
    Hay guys I've programmed a very simple range finder. The user can only select numbers 1 - 180 (axis) if the number is 90 or below i have to add 90 on to it if the number is 91 - 180 i have to take off 90 from it. Here's what i have $min_range = range(1,90); $max_range = range(91,180); if(in_array($axis, $min_range)){ $c = $axis + 90; }elseif(in_array($axis, $max_range)){ $c = $axis - 90; } Has anyone got a better solution

  • Doing a join across two databases with different collations on SQL Server and getting an error.

    - by Andrew G. Johnson
    I know, I know with what I wrote in the question I shouldn't be surprised. But my situation is slowly working on an inherited POS system and my predecessor apparently wasn't aware of JOINs so when I looked into one of the internal pages that loads for 60 seconds I see that it's a fairly quick, rewrite these 8 queries as one query with JOINs situation. Problem is that besides not knowing about JOINs he also seems to have had a fetish for multiple databases and surprise, surprise they use different collations. Fact of the matter is we use all "normal" latin characters that English speaking people would consider the entire alphabet and this whole thing will be out of use in a few months so a bandaid is all I need. Long story short is I need some kind of method to cast to a single collation so I can compare two fields from two databases. Exact error is: Cannot resolve the collation conflict between "SQL_Latin1_General_CP850_CI_AI" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.

  • MySql Query lag time?

    - by Click Upvote
    When there are multiple PHP scripts running in parallel, each making an UPDATE query to the same record in the same table repeatedly, is it possible for there to be a 'lag time' before the table is updated with each query? I have basically 5-6 instances of a PHP script running in parallel, having been launched via cron. Each script gets all the records in the items table, and then loops through them and processes them. However, to avoid processing the same item more than once, I store the id of the last item being processed in a seperate table. So this is how my code works: function getCurrentItem() { $sql = "SELECT currentItemId from settings"; $result = $this->db->query($sql); return $result->get('currentItemId'); } function setCurrentItem($id) { $sql = "UPDATE settings SET currentItemId='$id'"; $this->db->query($sql); } $currentItem = $this->getCurrentItem(); $sql = "SELECT * FROM items WHERE status='pending' AND id > $currentItem'"; $result = $this->db->query($sql); $items = $result->getAll(); foreach ($items as $i) { //Check if $i has been processed by a different instance of the script, and if so, //leave it untouched. if ($this->getCurrentItem() > $i->id) continue; $this->setCurrentItem($i->id); // Process the item here } But despite of all the precautions, most items are being processed more than once. Which makes me think that there is some lag time between the update queries being run by the PHP script, and when the database actually updates the record. Is it true? And if so, what other mechanism should I use to ensure that the PHP scripts always get only the latest currentItemId even when there are multiple scripts running in parrallel? Would using a text file instead of the db help?
