• select distinct over specific columns

  - by Midhat

  A query in a system I maintain returns QID AID DATA 1 2 x 1 2 y 5 6 t As per a new requirement, I do not want the (QID, AID)=(1,2) pair to be repeated. We also dont care what value is selected from "data" column. either x or y will do. What I have done is to enclose the original query like this SELECT * FROM (<original query text>) Results group by QID,AID Is there a better way to go about this? The original query uses multiple joins and unions and what not, So I would prefer not to touch it unless its absolutely necesary

  - by Ghommey

  Hey, I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell whether $myObject has a method called helloWorld or not?

• Do more specific css rules load better?

  - by bobobobo

  You can do this: .info { padding: 5px ; } Or, if you know it will be a div, you can do this div.info { padding: 5px ; } So, when there's a nested list.. you can do this.. div.info ul.navbar li.navitem a.sitelink { color: #f00; } Or you can do this a.sitelink { color: #f00; } Readability aside, which is better for the browser to parse/run?

• VS2008 is very slow on a specific large C++ solution

  - by VioletRose

  I have a solution with 21 C++ projects and 1 VB.NET project. The IDE responds very slowly when I simply move the carret in a file or try to open the menu. The process seems to take 50% of CPU for each movement. It only happens with this solution and only on my machine. The solution has total of 2380 source and header files, of which 1280 are header files. I tried to remove all connection to the source control (Perforce) but it didn't help. Also, I have Visual Assist installed but even after removing it (uninstall), the same behavior continued. Any idea?

• Eclipse - limiting a command's visibility to a specific perspective

  - by Tom

  How do I limit the visibility of an Eclipse command in menus and the toolbar to just one perspective? It is currently showing up in all perspectives, but it only makes sense to have it around when working in this particular perspective. It seems like this could be done with "contexts", but I was wondering if there was something simpler.

• limiting mysql results by range of a specific key INCLUDING DUPLICATES

  - by aVC

  I have a query SELECT p.*, m.*, (SELECT COUNT(*) FROM newPhotoonAlert n WHERE n.userIDfor='$id' AND n.threadID=p.threadID and n.seen='0') AS unReadCount FROM posts p JOIN myMembers m ON m.id = p.user_id LEFT JOIN following f ON (p.user_id = f.user_id AND f.follower_id='$id' AND f.request='0' AND f.status='1') JOIN myMembers searcher ON searcher.id = '$id' WHERE ((f.follower_id = searcher.id) OR m.id='$id') AND p.flagged <'5' ORDER BY p.threadID DESC,p.positionID It brings result as expected but I want to add Another CLAUSE to limit the results. Say a sample (minimal shown) set of data looks like this with the above query. threadID postID positionID url 564 1254 2 a.com 564 1245 1 a1.com 541 1215 3 b1.com 541 1212 2 b2.com 541 1210 1 b3.com 523 745 1 c1.com 435 689 2 d2.com 435 688 1 a4.com 256 345 1 s3.com 164 316 1 f1.com . . I want to get ROWS corresponding to 2 DISTINCT threadIDs starting from MAX, but I want to include duplicates as well. Something like AND p.threadID IN (Select just Two of all threadIDs currently selected, but include duplicate rows) So my result should be threadID postID positionID url 564 1254 2 a.com 564 1245 1 a1.com 541 1215 3 b1.com 541 1212 2 b2.com 541 1210 1 b3.com

• Javascript Getting specific element (of parent) by name

  - by Fluidbyte

  I'm using custom tags to define sections in an application, so I have something like this: <mysection> <form> <input name="myfield"> </form> </mysection> I'm using the following and able to get the tag (printed to console, everything is groovy) var parent = document.getElementsByTagName('mysection'); The issue I'm having is finding the child field by name: var myfield = parent.getElementsByName("myfield"); ...as I don't want to pick up on any other 'sections' that might have an input with the name 'myfield'. EDIT: var parent = document.getElementsByTagName('mysection')[0]; was suggested and returns to console the section contents, however, getElementsByName throws an error: Uncaught TypeError: Object #<NodeList> has no method 'getElementsByName'

• How to set up a specific registration on Database

  - by ymorenz

  I'm creating a database so I can access names of people from a university. But I would like to create a registration ID for each person like 1012607, of which the first 2 numbers would be the year (11 for 2011) and the third digit would be the semester they registered (1 in the beginning of the year and 2 in the end of the year). The other 4 digits would be incremental. I don't know how to code a prefixed number in MySQL that can change only the last 4 digits and after a year change the first 2 digits every time you have a new registration. Can someone please help me?
