  • Mysql question about UPDATE

    - by Beck
    UPDATE counter_reports SET `counter`=`counter`+1,`date`=? WHERE report_id IN( (SELECT report_id FROM counter_reports WHERE report_name="emails_sent" AND `year`=1 ORDER BY report_id DESC LIMIT 1), (SELECT report_id FROM counter_reports WHERE report_name="emails_sent" AND `month`=1 ORDER BY report_id DESC LIMIT 1), (SELECT report_id FROM counter_reports WHERE report_name="emails_sent" AND `week`=1 ORDER BY report_id DESC LIMIT 1), (SELECT report_id FROM counter_reports WHERE report_name="emails_sent" AND `day`=1 ORDER BY report_id DESC LIMIT 1) ) Is there any alternative for such sql? I need to update(increment by 1) last counter reports for day,week,month and year. If I'm adding manually, sql works fine, but with subqueries it fails to launch. Thanks. :)

  • Subversion Question - How to skip a revision...

    - by Albert
    So say I have the three latest revisions of an aspx file: 55,56, and 57. Revision 56 added a feature that I want to remove, but I also want to have the new features deployed in version 57. Is there any way I can merge version 55 with 57, leaving revision 56 out of the picture? If it matters, I'm using Tortoise SVN and Visual SVN, but I normally just use Tortoise. Thanks for any ideas.

  • Joomla User Login Question

    - by user277127
    I would like to enable users of my existing web app to login to Joomla with the credentials already stored in my web app's database. By using the Joomla 1.5 authentication plugin system -- http://docs.joomla.org/Tutorial:Creating_an_Authentication_Plugin_for_Joomla_1.5 -- I would like to bypass the Joomla registration process and bypass creating users in the Joomla database altogether. My thought had been that I could simply populate a User object, which would be stored in the Session, and that this would replace the need to store a user in the Joomla database. After looking through the code surrounding user management in Joomla, it seems like any time you interact with the User object, the database is being queried. It therefore seems like my initial idea won't work. Is that right? It looks like, in order to achieve the effect I want, I will have to actually register a user from within the authentication plugin at the time they first login. This is not ideal, so before I go forward with it, I wanted to check with Joomla developers whether it is possible to do what I described above. Thanks in advance -- I am new to Joomla and greatly appreciate your help!

  • PHP & MySQL query value question.

    - by space
    How can I use the first query's id value $row['id'] again after I run a second query inside the while loop statement? To show you what I mean here is a sample code below of what I'm trying to do. I hope I explained it right. Here is the code. $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc = mysqli_query($mysqli,"SELECT users.* FROM users WHERE user_id = 4"); if (!$dbc) { // There was an error...do something about it here... print mysqli_error($mysqli); } while($row = mysqli_fetch_assoc($dbc)) { echo '<div>User: ' . $row['id'] . '</div>'; echo '<div>Link To User' . $row['id'] . '</div>'; $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc2 = mysqli_query($mysqli,"SELECT COUNT(cid) as num FROM comments WHERE comments_id = $row[id]"); if (!$dbc2) { // There was an error...do something about it here... print mysqli_error($mysqli); } else { while($row = mysqli_fetch_array($dbc2)){ $num = $row['num']; } } echo '<div>User ' . $row['id'] . ' Comments# ' . $num . '</div>'; }

  • Basic CSS question regarding background images for divs

    - by Mike
    I'm a programmer trying to learn some css and I've already run into a stumbling block. I have the following HTML: <div class="container"> <div class="span-24 last"> Header </div> <div class="span-4"> Left sidebar </div> <div class="span-16"> <div class="span-8"> Box1 </div> <div class="span-4"> Box2 </div> <div class="span-4 last"> Box3 </div> <div class="span-16 last"> Main content </div> </div> <div class="span-4 last"> Right sidebar </div> <div class="span-24 last"> Footer </div> </div> In my css I have the following: body { background-color:#FFFFFF; } div.container { background:url(/images/bck.jpg); } I just want to display an image for the background area for the container div but nothing shows up. If I remove the background section from the css and add background-color:#000000; then I see a black background for the container div. What am I overlooking?

  • Question about custom events

    - by Malfist
    I'm making custom events for C# and sometimes it isn't working. This is how I'm making the event happen: private bool isDoorOpen; public bool IsDoorOpen { get { return isDoorOpen;} private set { isDoorOpen = value; DoorsChangeState(this, null);} } And these are the event declarations: //events public delegate void ChangedEventHandler(Elevator sender, EventArgs e); public event ChangedEventHandler PositionChanged; public event ChangedEventHandler DirectionChanged; public event ChangedEventHandler BreaksChangeState; public event ChangedEventHandler DoorsChangeState; This works as long as there are methods attached to the events, but if there isn't, it throws a null ref exception. What am I doing wrong?

    I know that by default ASP.NET ships with LocalSqlServer... I just uploaded my website and I did the following: <remove name="LocalSqlServer"/> <add name="LocalSqlServer" connectionString="Data Source=winsqlus03.lxa.perfora.net,1433; Initial Catalog=db323219488; User ID= dboxxxxxxxxx; Password=xxxxx;"/> And inside my App_Data I still have the ASPNETDB.MDF, when I tried to run it... What I got is: Could not find stored procedure 'dbo.aspnet_CheckSchemaVersion'. why is this?

  • Beginners PHP / mySQL question

    - by Reg H
    I'm brand new to PHP & MySQL, and one function I'm creating needs to access a large table or database. I've created the database and it's currently in a MySQL table, which I'm accessing with no problem. The table is 11,000 rows in length, with 8 columns (all text less than 8 characters long) - it's static, and will never change. Without getting too particular, my users will hit a button which will trigger scripts to access the data, say 500 times or more. So in general would it be better practice to include all of this data in a big 'switch' or 'if... then' conditional right in my scripts, rather than opening and accessing the database connection hundreds, or maybe even thousands of times? It just seems like that might be a bottleneck waiting to happen. Thanks!

  • android question about service and the method onstartcommand

    - by user516883
    In a service class there is a method to start the service. If that service gets done executing does it runs onstartcommand from the beginning? Is onstartcommand sorta like a loop as long as the service is running. For example i have onstartcommand { int x = 0; if(x == 0){ } else{ } } After that is complete does it run it again. If you know that answer please explain. I have read google explanation of services and it did not explain that part very well. Is onstartcommand sorta like a loop as long as the service is runnning

    we know algorithm how reverse array of n integers for (int i=0;i<n/2;i++){ swap(a[i],a[n-1-i]): } is this method better according the speed of algorithm or not because swap using xor is more fast then in other method here is code public class swap{ public static void main(String[]args){ int a[]=new int[]{2,4,5,7,8,11,13,12,14,24}; System.out.println(" array at the begining:"); for (int i=0;i<a.length;i++){ System.out.println(a[i]); } for (int j=0;j<a.length/2;j++){ a[j]^=a[a.length-1-j]; a[a.length-1-j]^=a[j]; a[j]^=a[a.length-1-j]; } System.out.println("reversed array:"); for (int j=0;j<a.length;j++){ System.out.println(a[j]); } } } //result array at the begining: 2 4 5 7 8 11 13 12 14 24 reversed array: 24 14 12 13 11 8 7 5 4 2
