  • How do I Fix SQL Server error: Order by items must appear in the select list if Select distinct is s

    - by Paula DiTallo 2007-2009 All Rights Reserved
    There's more than one reason why you may receive this error, but the most common reason is that your order by statement column list doesn't correlate with the values specified in your column list when you happen to be using DISTINCT. This is usually easy to spot and resolve. A more obscure reason may be that you are using a function around one of the selected columns --but omitting to use the same function around the same selected column name in the order by statement. Here's an example:   select distinct upper(columnA)   from [evaluate].[testTable]    order by columnA  asc   This statement will cause the "Order by items must appear in the select list if SELECT DISTINCT is specified."  error to appear not because distinct was used, but because the order by statement did not utilize the upper() fundtion around colunnA.  To correct this error, do this: select distinct upper(columnA)   from [evaluate].[testTable]    order by upper(columnA) asc

  • DENY select on sys.dm_db_index_physical_stats

    - by steveh99999
    Technorati Tags: security,DMV,permission,sys.dm_db_index_physical_stats I recently saw an interesting blog article by Paul Randal about the performance overhead of querying the sys.dm_db_index_physical_stats. So I was thinking, would it be possible to let non-sysadmin users query DMVs on a SQL server but stop them querying this I/O intensive DMV ? Yes it is, here’s how… 1. Create a new login for test purposes, with permissions to access AdventureWorks database only … CREATE LOGIN [test] WITH PASSWORD='xxxx', DEFAULT_DATABASE=[AdventureWorks] GO USE [AdventureWorks] GO CREATE USER [test] FOR LOGIN [test] WITH DEFAULT_SCHEMA=[dbo] GO 2.login as user test and issue command SELECT  * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks'),NULL,NULL,NULL,'DETAILED') gets error :-  Msg 297, Level 16, State 12, Line 1 The user does not have permission to perform this action. 3.As a sysadmin, issue command :- USE AdventureWorks GRANT VIEW DATABASE STATE TO [test] or GRANT VIEW SERVER STATE TO [test] if all databases can be queried via DMV. 4. Try again as user test to issue command SELECT * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks '),NULL,NULL,NULL,'DETAILED') -- now produces valid results from the DMV.. 5 now create the test user in master database, public role only USE master CREATE USER [test] FOR LOGIN [test] 6 issue command :- USE master DENY SELECT ON sys.dm_db_index_physical_stats TO [test] 7 Now go back to AdventureWorks using test login and try SELECT * FROM sys.dm_db_index_physical_stats(DB_ID('AdventureWorks’),NULL,NULL,NULL,’DETAILED') Now gets error... Msg 229, Level 14, State 5, Line 1 The SELECT permission was denied on the object 'dm_db_index_physical_stats', database 'mssqlsystemresource', schema 'sys'. but the user is still able to query all other non-IO-intensive DMVs. If the user attempts to view the index physical stats via a builtin management studio report  – see recent blog post by Pinal Dave they get an error also

  • Problem retrieving multiple instances of the same asp.net session variable

    - by sw1sh
    I'm having problems with retrieving multiple instances of a session variable from an InProc session state. In the following code I persist a simple BusinessObject into a session variable on the Page_Load event. On the click of a button I try to retrieve the object back into 2 new declared instances of the same BusinessObject. All works great until I change one of the properties in the first instance, it changes the second instance as well. Is this normal behaviour? I would have thought as these were new instances they wouldn’t demonstrate static behaviour? Any ideas where I'm going wrong? Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then ' create a new instance of a business object and set a containg variable Dim BO As New BusinessObject BO.SomeVariable = "test" ' persist to inproc session Session("BO") = BO End If End Sub Protected Sub btnRetrieveSessionVariable_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnRetrieveSessionVariable.Click ' retrieve the session variable to a new instance of BusinessObject Dim BO1 As New BusinessObject If Not Session("BO") Is Nothing Then BO1 = Session("BO") ' retrieve the session variable to a new instance of BusinessObject Dim BO2 As New BusinessObject If Not Session("BO") Is Nothing Then BO2 = Session("BO") ' change the property value on the first instance BO1.SomeVariable = "test2" ' why has this changed on both instances? Dim strBO1Property As String = BO1.SomeVariable Dim strBO2Property As String = BO2.SomeVariable End Sub ' simple BusinessObject class Public Class BusinessObject Private _SomeVariable As String Public Property SomeVariable() As String Get Return _SomeVariable End Get Set(ByVal value As String) _SomeVariable = value End Set End Property End Class

  • Binding a select in a client template

    - by Bertrand Le Roy
    I recently got a question on one of my client template posts asking me how to bind a select tag’s value to data in client templates. I was surprised not to find anything on the web addressing the problem, so I thought I’d write a short post about it. It really is very simple once you know where to look. You just need to bind the value property of the select tag, like this: <select sys:value="{binding color}"> If you do it from markup like here, you just need to use the sys: prefix. It just works. Here’s the full source code for my sample page: <!DOCTYPE html> <html> <head> <title>Binding a select tag</title> <script src=http://ajax.microsoft.com/ajax/beta/0911/Start.js type="text/javascript"></script> <script type="text/javascript"> Sys.require(Sys.scripts.Templates, function() { var colors = [ "red", "green", "blue", "cyan", "purple", "yellow" ]; var things = [ { what: "object", color: "blue" }, { what: "entity", color: "purple" }, { what: "thing", color: "green" } ]; Sys.create.dataView("#thingList", { data: things, itemRendered: function(view, ctx) { Sys.create.dataView( Sys.get("#colorSelect", ctx), { data: colors }); } }); }); </script> <style type="text/css"> .sys-template {display: none;} </style> </head> <body xmlns:sys="javascript:Sys"> <div> <ul id="thingList" class="sys-template"> <li> <span sys:id="thingName" sys:style-color="{binding color}" >{{what}}</span> <select sys:id="colorSelect" sys:value="{binding color}" class="sys-template"> <option sys:value="{{$dataItem}}" sys:style-background-color="{{$dataItem}}" >{{$dataItem}}</option> </select> </li> </ul> </div> </body> </html> This produces the following page: Each of the items sees its color change as you select a different color in the drop-down. Other details worth noting in this page are the use of the script loader to get the framework from the CDN, and the sys:style-background-color syntax to bind the background color style property from markup. Of course, I’ve used a fair amount of custom ASP.NET Ajax markup in here, but everything could be done imperatively and with completely clean markup from the itemRendered event using Sys.bind.

  • Flex - Drag and drop - Drop a subset of multiple items

    - by flanagann
    I'm developing two DataGrid with drag and drop support. Multiple items can be selected from the source data grid, and dropped into the target data grid. I'm using an drag and drop event listener which completes the operation only in certain cases. I'm using event.preventDefault() but it doesn't work, since it stops the drag and drop from all the items. My aim is, for example, finally dropping 2 elements from the total 4 elements that I previously selected. public function onDropPermission(event:DragEvent):void { var sourceGrid:mx.controls.DataGrid = new mx.controls.DataGrid(); sourceGrid = event.dragInitiator as mx.controls.DataGrid; var targetGrid:mx.controls.DataGrid = new mx.controls.DataGrid(); targetGrid = event.target as mx.controls.DataGrid; var i:int; for (i = 0; i < sourceGrid.selectedIndices.length; i++) { var j:int; for (j = 0; j < dataGroupPermissions.length; j++) { var permission:Permission = new Permission; permission = dataGroupPermissions[j] as Permission; if (permission.id == sourceGrid.selectedItems[i].id) { event.preventDefault(); } } } }

  • SQL SERVER – Select the Most Optimal Backup Methods for Server

    - by pinaldave
    Backup and Restore are very interesting concepts and one should be very much with the concept if you are dealing with production database. One never knows when a natural disaster or user error will surface and the first thing everybody wants is to get back on point in time when things were all fine. Well, in this article I have attempted to answer a few of the common questions related to Backup methodology. How to Select a SQL Server Backup Type In order to select a proper SQL Server backup type, a SQL Server administrator needs to understand the difference between the major backup types clearly. Since a picture is worth a thousand words, let me offer it to you below. Select a Recovery Model First The very first question that you should ask yourself is: Can I afford to lose at least a little (15 min, 1 hour, 1 day) worth of data? Resist the temptation to save it all as it comes with the overhead – majority of businesses outside finances can actually afford to lose a bit of data. If your answer is YES, I can afford to lose some data – select a SIMPLE (default) recovery model in the properties of your database, otherwise you need to select a FULL recovery model. The additional advantage of the Full recovery model is that it allows you to restore the data to a specific point in time vs to only last backup time in the Simple recovery model, but it exceeds the scope of this article Backups in SIMPLE Recovery Model In SIMPLE recovery model you can select to do just Full backups or Full + Differential. Full Backup This is the simplest type of backup that contains all information needed to restore the database and should be your first choice. It is often sufficient for small databases, but note that it makes a big impact on the performance of your database Full + Differential Backup After Full, Differential backup picks up all of the changes since the last Full backup. This means if you made Full, Diff, Diff backup – the last Diff backup contains all of the changes and you don’t need the previous Differential backup. Differential backup is obviously smaller and carries less performance overhead Backups in FULL Recovery Model In FULL recovery model you can select Full + Transaction Log or Full + Differential + Transaction Log backup. You have to create Transaction Log backup, because at that time the log is being truncated. Otherwise your Transaction Log will grow uncontrollably. Full + Transaction Log Backup You would always need to perform a Full backup first. Then a series of Transaction log backup. Note that (in contrast to Differential) you need ALL transactions to log since the last Full of Diff backup to properly restore. Transaction log backups have the smallest performance overhead and can be performed often. Full + Differential + Transaction Log Backup If you want to ease the performance overhead on your server, you can replace some of the Full backup in the previous scenario with Differential. You restore scenario would start from Full, then the Last Differential, then all of the remaining transactions log backups Typical backup Scenarios You may say “Well, it is all nice – give me the examples now”. As you may already know, my favorite SQL backup software is SQLBackupAndFTP. If you go to Advanced Backup Schedule form in this program and click “Load a typical backup plan…” link, it will give you these scenarios that I think are quite common – see the image below. The Simplest Way to Schedule SQL Backups I hate to repeat myself, but backup scheduling in SQL agent leaves a lot to be desired. I do not know the simple way to schedule your SQL server backups than in SQLBackupAndFTP – see the image below. The whole backup scheduling with compression, encryption and upload to a Network Folder / HDD / NAS Drive / FTP / Dropbox / Google Drive / Amazon S3 takes just a few minutes – see my previous post for the review. Final Words This post offered an explanation for major backup types only. For more complicated scenarios or to research other options as usually go to MSDN.

  • DQL delete from multiple tables (doctrine)

    - by singer
    Need to perform DQL delete from multple related tables. In SQL it is something like this: DELETE r1,r2 FROM ComRealty_objects r1, com_realty_objects_phones r2 WHERE r1.id IN (10,20) AND r2.id_object IN (10,20) I need to perform this statement using DQL, but I'm stuck on this :( <?php $dql = Doctrine_Query::create() ->delete('phones, comrealtyobjects') ->from('ComRealtyObjects comrealtyobjects') ->from('ComRealtyObjectsPhones phones') ->whereIn("comrealtyobjects.id", $ids) ->whereIn("phones.id_object", $ids); echo($dql->getSqlQuery()); ?> But DQL parser gives me this result: DELETE FROM `com_realty_objects_phones`, `ComRealty_objects` WHERE (`id` IN (?) AND `id_object` IN (?)) Searching google and stack overflow I found this(useful) topic: http://stackoverflow.com/questions/2247905/what-is-the-syntax-for-a-multi-table-delete-on-a-mysql-database-using-doctrine But this is not exactly my case - there was delete from single table. If there is a way to override dql parser behaviour? Or maybe some other way to delete records from multiple tables using doctrine. Note: If you are using doctrine behaviours(Doctrine_Record_Generator) you need first to initialize those tables using Doctrine_Core::initializeModels() to perform DQL operations on them.

  • how to handle multiple profiles per user?

    I'm doing something that doesn't feel very efficient. From my code below, you can probably see that I'm trying to allow for multiple profiles of different types attached to my custom user object (Person). One of those profiles will be considered a default and should have an accessor from the Person class. Can this be done better? from django.db import models from django.contrib.auth.models import User, UserManager class Person(User): public_name = models.CharField(max_length=24, default="Mr. T") objects = UserManager() def save(self): self.set_password(self.password) super(Person, self).save() def _getDefaultProfile(self): def_teacher = self.teacher_set.filter(default=True) if def_teacher: return def_teacher[0] def_student = self.student_set.filter(default=True) if def_student: return def_student[0] def_parent = self.parent_set.filter(default=True) if def_parent: return def_parent[0] return False profile = property(_getDefaultProfile) def _getProfiles(self): # Inefficient use of QuerySet here.

  • How to manage multiple python versions ?

    - by Gyom
    short version: how can I get rid of the multiple-versions-of-python nightmare ? long version: over the years, I've used several versions of python, and what is worse, several extensions to python (e.g. pygame, pylab, wxPython...). Each time it was on a different setup, with different OSes, sometimes different architectures (like my old PowerPC mac). Nowadays I'm using a mac (OSX 10.6 on x86-64) and it's a dependency nightmare each time I want to revive script older than a few months. Python itself already comes in three different flavours in /usr/bin (2.5, 2.6, 3.1), but I had to install 2.4 from macports for pygame, something else (cannot remember what) forced me to install all three others from macports as well, so at the end of the day I'm the happy owner of seven (!) instances of python on my system. But that's not the problem, the problem is, none of them has the right (i.e. same set of) libraries installed, some of them are 32bits, some 64bits, and now I'm pretty much lost. For example right now I'm trying to run a three-year-old script (not written by me) which used to use matplotlib/numpy to draw a real-time plot within a rectangle of a wxwidgets window. But I'm failing miserably: py26-wxpython from macports won't install, stock python has wxwidgets included but also has some conflict between 32 bits and 64 bits, and it doesn't have numpy... what a mess ! Obviously, I'm doing things the wrong way. How do you usally cope with all that chaos ?e

  • A linked list with multiple heads in Java

    Hi, I have a list in which I'd like to keep several head pointers. I've tried to create multiple ListIterators on the same list but this forbid me to add new elements in my list... (see Concurrent Modification exception). I could create my own class but I'd rather use a built-in implementation ;) To be more specific, here is an inefficient implementation of two basic operations and the one wich doesn't work : class MyList <E { private int[] _heads; private List<E _l; public MyList ( int nbHeads ) { _heads = new int[nbHeads]; _l = new LinkedList<E(); } public void add ( E e ) { _l.add(e); } public E next ( int head ) { return _l.get(_heads[head++]); // ugly } } class MyList <E { private Vector<ListIterator<E _iters; private List<E _l; public MyList ( int nbHeads ) { _iters = new Vector<ListIterator<E(nbHeads); _l = new LinkedList<E(); for( ListIterator<E iter : _iters ) iter = _l.listIterator(); } public void add ( E e ) { _l.add(e); } public E next ( int head ) { // ConcurrentModificationException because of the add() return _iters.get(head).next(); } } Emile

  • iPhone SDK allow touches to affect multiple views

    - by Parad0x13
    I have a main view that has has two buttons on it that control methods to display the next image and display the previous image. In this case the 'Image' is a class that inherits from UIImageView and has multiple pictures on it that you can interact with, and I call this class a 'Pane'. The pane itself handles all the user interaction itself while the main view controls the display of next and previous panes with the buttons. Here is my dilemma, because the pane fully covers the main view it wont allow for the user to tap the buttons on the main view! So once a pane pops up you cannot change it via the buttons! Is there a way to allow touches through transparent parts of a view, or if not how in the world do I achieve this?! I cannot pass touchesBegan or any of those methods from the pane to the superview because all of the button touch methods are created in the xib file. I cannot insert the pane under the control panel because then you wouldn't be able to interact with the pane. And as far as I know theres no way to pass touch events to every single pane within the paneHoldingArray that belongs to the main view I cannot add the command buttons inside of the pane because I want to be able to replace the command button's image with a thumbprint render of the next/previous pane. I've been stuck on this for a very long time, please somebody help me out with a fix action or a new way to re-engineer the code so that it will work!

  • django: How to make one form from multiple models containing foreignkeys

    I am trying to make a form on one page that uses multiple models. The models reference each other. I am having trouble getting the form to validate because I cant figure out how to get the id of two of the models used in the form into the form to validate it. I used a hidden key in the template but I cant figure out how to make it work in the views My code is below: views: def the_view(request, a_id,): if request.method == 'POST': b_form= BForm(request.POST) c_form =CForm(request.POST) print "post" if b_form.is_valid() and c_form.is_valid(): print "valid" b_form.save() c_form.save() return HttpResponseRedirect(reverse('myproj.pro.views.this_page')) else: b_form= BForm() c_form = CForm() b_ide = B.objects.get(pk=request.b_id) id_of_a = A.objects.get(pk=a_id) return render_to_response('myproj/a/c.html', {'b_form':b_form, 'c_form':c_form, 'id_of_a':id_of_a, 'b_id':b_ide }) models class A(models.Model): name = models.CharField(max_length=256, null=True, blank=True) classe = models.CharField(max_length=256, null=True, blank=True) def __str__(self): return self.name class B(models.Model): aid = models.ForeignKey(A, null=True, blank=True) number = models.IntegerField(max_length=1000) other_number = models.IntegerField(max_length=1000) class C(models.Model): bid = models.ForeignKey(B, null=False, blank=False) field_name = models.CharField(max_length=15) field_value = models.CharField(max_length=256, null=True, blank=True) forms from mappamundi.mappa.models import A, B, C class BForm(forms.ModelForm): class Meta: model = B exclude = ('aid',) class CForm(forms.ModelForm): class Meta: model = C exclude = ('bid',) B has a foreign key reference to A, C has a foreign key reference to B. Since the models are related, I want to have the forms for them on one page, 1 submit button. Since I need to fill out fields for the forms for B and C & I dont want to select the id of B from a drop down list, I need to somehow get the id of the B form into the form so it will validate. I have a hidden field in the template, I just need to figure how to do it in the views

My implementation is as: IViwer.h (only Header file , no CPP file) : #ifndef IVIEWER_H_ #define IVIEWER_H_ class IViewer { public: //IViewer(); ///virtual //~IViewer(); virtual void init()=0; }; #endif /* IVIEWER_H_ */ My derived class. PlaneViewer.h #ifndef PLANEVIEWER_H #define PLANEVIEWER_H #include <QtGui/QWidget> #include "ui_planeviewer.h" #include "IViewer.h" class PlaneViewer : public QWidget , public IViewer { Q_OBJECT public: PlaneViewer(QWidget *parent = 0); ~PlaneViewer(); void init(); //do I have to define here also ? private: Ui::PlaneViewerClass ui; }; #endif // PLANEVIEWER_H PlaneViewer.cpp #include "planeviewer.h" PlaneViewer::PlaneViewer(QWidget *parent) : QWidget(parent) { ui.setupUi(this); } PlaneViewer::~PlaneViewer() { } void PlaneViewer::init(){ } My questions are: Is it necessary to declare method init() in PlaneViewer interface also , because it is already defined in IView? 2.I cannot complie above code ,give error : PlaneViewer]+0x28): undefined reference to `typeinfo for IViewer' collect2: ld returned 1 exit status Do I have to have implementation for IView in CPP file?

  • Using Alt-select in SSMS, Word, and elsewhere

    - by John Paul Cook
    A surprising number of database people and Windows users in general don’t know about Alt select . This is a Windows technique not unique to SSMS that allows a user to select an arbitrary rectangular region of text and delete it, cut it, or copy it. Where I find Alt select particularly useful in SSMS is when I have a bunch of inline comments that are too far to the right. I want to delete much of the whitespace in front of them to move them to the left without disturbing any of the rest of the T-SQL....(read more)

  • How to link jQuery UI datepicker functionality with a select list

    - by take2
    I'm trying to connect jQuery UI's datepicker with a select list. I have found one explanation on jQuery's Forum ( forum.jquery.com/topic/jquery-ui-datepicker-with-select-lists), but I can't get it working. There are input and select list both declared: <select id="selectMonth"><option value="01">Jan</option><option value="02">Feb</option> <option value="03">Mar</option><option value="04">Apr</option>...</select> <select id="selectDay"><option value="01">1</option><option value="02">2</option> <option value="03">3</option><option value="04">4</option>...</select> <select id="selectYear"><option value="2012">2012</option><option value="2013">2013</option> <option value="2014">2014</option>...</select> <p>Date: <input type="text" id="selectedDatepicker" /></p> This is the script: $(function() { $('#selectedDatepicker').datepicker({ beforeShow: readSelected, onSelect: updateSelected, minDate: new Date(2012, 1 - 1, 1), maxDate: new Date(2014, 12 - 1, 31), showOn: 'both', buttonImageOnly: true, buttonImage: 'img/calendar.gif'}); // Prepare to show a date picker linked to three select controls function readSelected() { $('#selectedDatepicker').val($('#selectMonth').val() + '/' + $('#selectDay').val() + '/' + $('#selectYear').val()); return {}; } // Update three select controls to match a date picker selection function updateSelected(date) { $('#selectMonth').val(date.substring(0, 2)); $('#selectDay').val(date.substring(3, 5)); $('#selectYear').val(date.substring(6, 10)); } }); And here is the fiddle: http://jsfiddle.net/xKXZm/ They are not connected properly, the only "connected behaviour" is that when you click on the input button, it picks up the value of the select list. On the other hand, the select list never picks up the value of the input nor will the input pick up the value of the select list until you click on it.

  • SQL Grouping with multiple joins combining results incorrectly

    - by Matt
    Hi I'm having trouble with my query combining records when it shouldn't. I have two tables Authors and Publications, they are related by Publication ID in a many to many relationship. As each author can have many publications and each publication has many Authors. I want my query to return every publication for a set of authors and include the ID of each of the other authors that have contributed to the publication grouped into one field. (I am working with mySQL) I have tried to picture it graphically below Table: authors Table:publications AuthorID | PublicationID PublicationID | PublicationName 1 | 123 123 | A 1 | 456 456 | B 2 | 123 789 | C 2 | 789 3 | 123 3 | 456 I want my result set to be the following AuthorID | PublicationID | PublicationName | AllAuthors 1 | 123 | A | 1,2,3 1 | 456 | B | 1,3 2 | 123 | A | 1,2,3 2 | 789 | C | 2 3 | 123 | A | 1,2,3 3 | 456 | B | 1,3 This is my query Select Author1.AuthorID, Publications.PublicationID, Publications.PubName, GROUP_CONCAT(TRIM(Author2.AuthorID)ORDER BY Author2.AuthorID ASC)AS 'AuthorsAll' FROM Authors AS Author1 LEFT JOIN Authors AS Author2 ON Author1.PublicationID = Author2.PublicationID INNER JOIN Publications ON Author1.PublicationID = Publications.PublicationID WHERE Author1.AuthorID ="1" OR Author1.AuthorID ="2" OR Author1.AuthorID ="3" GROUP BY Author2.PublicationID But it returns the following instead AuthorID | PublicationID | PublicationName | AllAuthors 1 | 123 | A | 1,1,1,2,2,2,3,3,3 1 | 456 | B | 1,1,3,3 2 | 789 | C | 2 It does deliver the desired output when there is only one AuhorID in the where statement. I have not been able to figure it out, does anyone know where i'm going wrong?

  • jQuery indexOf select box manipulation

    - by kenny99
    Hi, I'm trying to figure out how to remove options from a select box when that option has been selected in an adjacent select box. Basically the user has the option to add multiple records here via select boxes, but I want to remove the list of options available to them so that, for example, they can't enter the same value in two select boxes. When an Add More button is clicked, I fade in the next select box container. A number of select boxes have been generated by PHP and I use JS to hide them. Each select box has a unique number appended to the ID, so i want to access those select boxes which contain the string "other_pet_types", then I want to iterate through the currently visible ones and build an array of the values which have been selected, which I will then remove from the list of options in the newly displayed select box. This is what I have so far, but it's definitely not right - I can't get the initial test on the ID to work. Any pointers greatly appreciated as i realise i'm pretty wide of the mark at the moment! var vals = new Array(); //build array with currently selected options $('p.mult_entries select').each(function(){ vals += $(this).val(); }); $("p.mult_entries:hidden:first").fadeIn("slow", function() { $(this).find(('select').attr('id').indexOf('other_pet_types') > 0).each(function(){ console.log($(this).val()); //as expected prints nothing - need to iterate through the options of the above select //once i extract the correct values, iterate through new select box and use inArray to remove options where that value already exists in one of previous select boxes }); });

  • Adding date to multiple fields via datepicker

    - by Andy
    i have a form in drupal with jquery based date module. there are multiple fields with date picker enabled. i want to set the value of all of them (they all have class .date-popup-init) to the value of the first field (#edit-field, the 'from' date) when that field is set. my code so far: <script type="text/javascript"> var DatePicked = function() { var firstdate = $("#edit-field"); var updater = firstdate.datepicker("getDate"); $(".date-popup-init").each(function(){ $(this).datepicker("setDate", updater); }); } $(function() { $("#edit-field").datepicker({ onSelect: DatePicked }); }); </script> this seems to randomly work; it sets the date of some fields to the value of #edit-field, seemingly different fields each time. also, the form adds more datepicker-enabled fields via ajax. is there any way to ensure that all these new fields, when they load, pick up the value of #edit-field as well? disclaimer: last night was my first attempt at javascript of any kind. i have a basic idea now. the above was cobbled through countless google examples.
