• Access 2007: Dynamic SQL to be run when opening a report

  - by blockcipher

  I'm trying to have some SQL execute when I open a report. This works fine when I try to match on a column that's an integer with an integer, but when I try to match on a "text" column, it keeps popping up a dialog asking for what you want to filter on. Here's a somple query: select person_phone_numbers.person_id from person_phone_numbers where phone_number = '444-444-4444' This is actually a sub-query I'm trying to use, but this is where the problem is. If I change it to this it works fine: select person_phone_numbers.person_id from person_phone_numbers where phone_id = 2 I put this in the OnOpen event and I'm assigning it to Me.RecordSource if that makes a difference. My goal here is to have a form accept query parameter(s) and have it open a report with the results. Any thoughts on why it wants to ask for a parameter vs. just running the query the way I have it?

• SQL query - choosing 'last updated' record in a group, better db design?

  - by Jimmy

  Hi, Let's say I have a MySQL database with 3 tables: table 1: Persons, with 1 column ID (int) table 2: Newsletters, with 1 column ID (int) table 3: Subscriptions, with columns Person_ID (int), Newsletter_ID (int), Subscribed (bool), Updated (Datetime) Subscriptions.Person_ID points to a Person, and Subscription.Newsletter_ID points to a Newsletter. Thus, each person may have 0 or more subscriptions to 0 or more magazines at once. The table Subscriptions will also store the entire history of each person's subscriptions to each newsletter. If a particular Person_ID-Newsletter_ID pair doesn't have a row in the Subscriptions table, then it's equivalent to that pair having a subscription status of 'false'. Here is a sample dataset Persons ID 1 2 3 Newsletters ID 4 5 6 Subscriptions Person_ID Newsletter_ID Subscribed Updated 2 4 true 2010-05-01 3 4 true 2010-05-01 3 5 true 2010-05-10 3 4 false 2010-05-15 Thus, as of 2010-05-16, Person 1 has no subscription, Person 2 has a subscription to Newsletter 4, and Person 3 has a subscription to Newsletter 5. Person 3 had a subscription to Newsletter 4 for a while, but not anymore. I'm trying to do 2 kinds of query. A query that shows everyone's active subscriptions as of query time (we can assume that updated will never be in the future -- thus, this means returning the record with the latest 'updated' value for each Person_ID-Newsletter_ID pair, as long as Subscribed is true (if the latest record for a Person_ID-Newsletter_ID pair has a Subscribed status of false, then I don't want that record returned)). A query that returns all active subscriptions for a specific newsletter - same qualification as in 1. regarding records with 'false' in the Subscribed column. I don't use SQL/databases often enough to tell if this design is good, or if the SQL queries needed would be slow on a database with, say, 1M records in the Subscriptions table. I was using the Visual query builder tool in Visual Studio 2010 but I can't even get the query to return the latest updated record for each Person_ID-Newsletter_ID pair. Is it possible to come up with SQL queries that don't involve using subqueries (presumably because they would become too slow with a larger data set)? If not, would it be a better design to have a separate Subscriptions_History table, and every time a subscription status for a Person_ID-Newsletter-ID pair is added to Subscriptions, any existing record for that pair is moved to Subscriptions_History (that way the Subscriptions table only ever contains the latest status update for any Person_ID-Newsletter_ID pair)? I'm using .net on Windows, so would it be easier (or the same, or harder) to do this kind of queries using Linq? Entity Framework? Thanks!

• What is the best way to store categorical references in SQL tables?

  - by jlafay

  I'm wanting to store a wide array of categorical data in MySQL database tables. Let's say that for instance I want to to information on "widgets" and want to categorize attributes in certain ways, i.e. shape category. For instance, the widgets could be classified as: round, square, triangular, spherical, etc. Should these categories be stored within a table to reference them best from an application? Another possibility, I would imagine, would be to add a column to widgets that contained a shape column that contained a tiny int. That way my application could search shapes by that and then use a coordinating enum type that would map the shape int meanings. Which would be best? Or is there another solution that I'm not thinking of yet?

  I've just downloaded MochaUI, and I'm playing around trying to build an interface. I've successfully created windows, but I'm having trouble when it comes to layouts with columns. I've included all of the libraries in the same order as the demo, and this is in my init code: window.addEvent('domready', function(){ new MochaUI.Column({ id: 'sideColumn1', placement: 'left', width: 200, resizeLimit: [100, 300] }); }); When run, no column is created and I get the error: A is null Does anyone have any ideas? Thanks!

• LinkButton child controls render

  - by Alex

  Hi. I want to have a LinkButton that adds 'span' tag around the text. protected override void Render(HtmlTextWriter writer) { Text = String.Concat("<span>", Text, "</span>"); base.Render(writer); } It's works perfectly, but only if I add text like this: <cc:TestLinkButton ID="TestLinkButton" runat="server" Text="SomeText"> </cc:TestLinkButton> If I want to add some image I will write something like this: <cc:TestLinkButton ID="LinkButton1" runat="server"> <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/icon_holiday.png" BorderWidth="0" /> SomeText </cc:TestLinkButton> In this case Text property will be empty, because actualy "SomeText" is child control property. So question is is how to add tag around child controls.

• Find all html characters in drop-down option text and replace them via jQuery

  - by Jon Harding

  I have a dropdown menu that pulls in text from a database column. The database column can include HTML mark-up. In the drop-down I obviously don't need that in the text. I am working on some jquery and it partially accomplished what I'm looking for. However, it seems to only be replacing the first instance of each character $('select option').each(function() { this.text = this.text.replace('&nbsp;', ' '); this.text = this.text.replace('<div>', '' ); this.text = this.text.replace('</div>', '' ); }); Here is the HTML for the drop-down: <select name="ctl00$SubPageBody$ClassList" id="ctl00_SubPageBody_ClassList"> <option value="196">Four Week Series: July 19, 2012, 11:00am-12:00pm&<div>July 26, 2012, 11:00am-12:00pm&nbsp;</div><div>August 2, 2012, 11:00am-12:00pm</div><div>August 9, 2012, 11:00am-12:00pm</div></option> </select>

• Flex bug?? Get messed up stacked ColumnChart with type="100%"

  - by Nir

  I am trying to do a stacked Column chart with type="100%" and a mixture of positive and negative values. When all the values are positive, is functions well, but when negative numbers come to the game, it looks totally messed up. When I also look at Adobe documentation (look here), I see the following code for stacked column chart involving negative numbers: <?xml version="1.0"?> <!-- charts/StackedNegative.mxml --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script><![CDATA[ import mx.collections.ArrayCollection; [Bindable] public var expenses:ArrayCollection = new ArrayCollection([ {Month:"Jan", Profit:-2000, Expenses:-1500}, {Month:"Feb", Profit:1000, Expenses:-200}, {Month:"Mar", Profit:1500, Expenses:-500} ]); ]]></mx:Script> <mx:Panel title="Column Chart"> <mx:ColumnChart id="myChart" dataProvider="{expenses}" showDataTips="true"> <mx:horizontalAxis> <mx:CategoryAxis dataProvider="{expenses}" categoryField="Month" /> </mx:horizontalAxis> <mx:series> <mx:ColumnSet type="stacked" allowNegativeForStacked="true"> <mx:series> <mx:ColumnSeries xField="Month" yField="Profit" displayName="Profit" /> <mx:ColumnSeries xField="Month" yField="Expenses" displayName="Expenses" /> </mx:series> </mx:ColumnSet> </mx:series> </mx:ColumnChart> <mx:Legend dataProvider="{myChart}"/> </mx:Panel> </mx:Application> It works fine. But try to change: <mx:ColumnSet type="stacked" allowNegativeForStacked="true"> to: <mx:ColumnSet type="100%" allowNegativeForStacked="true"> and you'll see that it doesn't on January data, where both values are negative, the chart shows as if they are positive, and on the other two where one value is positive and the other is negative, it shows only the positive part as 100%... Isn't it a Flex Bug? I have my own case with such data and it behaves wrong the same way. I'd expect that if it has 800 stacked on -200, it will show 80% up and 20% down, totalling 100%. BTW: Using Flex 4, though these are all mx components. Thanks a lot and regards from Berlin, Germany, Nir.

• Rails Authlogic Prevent User from Changing their Login/Username

  - by bob

  Hello, I have implemented Authlogic. I believe that this isn't an authlogic specific quesetion. Assume that I have a User model and each User has a column in the database called "login". Upon creating a user, the login column is populated. However, I don't want the user to be able to change their login once they set it. Currently, I have removed the text field in the _form.html.erb file in my views for users. However, it can probably still be accessed through the url right? How can I make it so that once a login is set, it can not be changed at all?

• R- delete rows in multiple columns by unique number

  - by Vincent Moriarty

  Given data like this C1<-c(3,-999.000,4,4,5) C2<-c(3,7,3,4,5) C3<-c(5,4,3,6,-999.000) DF<-data.frame(ID=c("A","B","C","D","E"),C1=C1,C2=C2,C3=C3) How do I go about removing the -999.000 data in all of the columns I know this works per column DF2<-DF[!(DF$C1==-999.000 | DF$C2==-999.000 | DF$C3==-999.000),] But I'd like to avoid referencing each column. I am thinking there is an easy way to reference all of the columns in a particular data frame aka: DF3<-DF[!(DF[,]==-999.000),] or DF3<-DF[!(DF[,(2:4)]==-999.000),] but obviously these do not work And out of curiosity, bonus points if you can me why I need that last comma before the ending square bracket as in: ==-999.000),]

• I have to do two seemingly mutually exclusive things on leaving an asp:textbox. Please help me get

  - by aape

  This project has gone from being a simple '99 Ford F-150 to the Homer. I've got controls with a gridview with textboxes for data entry. All the user controls on the pages are in AJAX updatepanels. User types in a database column or budget entity or some other financial thing they want to include in the report. The textboxes in the gridview have autopostback = true set. overly long background info When the user leaves the textbox, during the postback (triggered by onTextChanged) I do some validation back on the server on their entry - regexs, do they have rights to that column, is that column locked, etc. If it fails, I put a error message next to the textbox. If it passes, I wipe out any title or error that used to be next to the code. Focus is getting lost from the postback if they're tabbing out of the box, rather than going to the next textbox in the gridview. So to fix that I need, if their leaving the tb via the tab key, to also figure out what textbox or gridviewrow they're on, if they're not on the last row, and after the validation and labeling, put the focus on the textbox in the next row. I can't figure out how, in ontextchanged, to find what caused me to leave the textbox, so I'm thinking use javascript onkeyup to test the key pressed and then find the next box etc, but the ontextchanged fires first and then the js never does, and also, since the control is all AJAXed, the javascript can't find the textboxes because when you enter the page everything is collapsed (the requirements people loooove to collapse and expand things), and so when it's expanded, all the 'new' textboxes are up in the viewstate stuff in the page source, and not down where javascript can see them. The questions So I'm wondering if I can have an onblur in the javascript that can trigger a postback where I can do my validation and such, and either 1) include the keypressed or pick it out of sender in the event or 2) followup the onblur with onkeyup and somehow figure out what textbox is next on the grid and throw focus there. Or, is there another .NET based approach that could work for this? In terms of tearing the whole thing down and starting from scratch, I couldn't sell that to the bosses, I'm past the point of no return as far as that goes.

• Mercurial (hg) commit only certain files

  Hi I'm trying to commit only certain files with hg. Because of of hg having auto-add whenever I try to commit a change it wants to commit all files. But I don't want that because certain files are not "ready" yet. There is hg commit -I thefile.foo, but this is only for one file. The better way for me would be if I can turn off auto-add as in git. Is this possible? thx

• Simplest one-to-many Map case in Hibernate doesn't work in MySQL

  - by Malvolio

  I think this is pretty much the simplest case for mapping a Map (that is, an associative array) of entities. @Entity @AccessType("field") class Member { @Id protected long id; @OneToMany(cascade = CascadeType.ALL, fetch=FetchType.LAZY) @MapKey(name = "name") private Map<String, Preferences> preferences = new HashMap<String, Preferences>(); } @Entity @AccessType("field") class Preferences { @ManyToOne Member member; @Column String name; @Column String value; } This looks like it should work, and it does, in HSQL. In MySQL, there are two problems: First, it insists that there be a table called Members_Preferences, as if this were a many-to-many relationship. Second, it just doesn't work: since it never populates Members_Preferences, it never retrieves the Preferences. [My theory is, since I only use HSQL in memory-mode, it automatically creates Members_Preferences and never really has to retrieve the preferences map. In any case, either Hibernate has a huge bug in it or I'm doing something wrong.]

• Weird Animation when inserting a row in UITableView

• Are table headers only for the top row in html?

  Hi, I always see the th tag only used in the first row of the table. Is there some specific reason why it can't be used to create 'left' headers along the leftmost column. Is this bad form, or is this ok. Basically, a table with headings on the top row and the leftmost column, with the very top left square being empty. e.g. <table> <tr> <th/> <!--empty--> <th>Top 1</th> <th>Top 2</th></tr> <tr> <th>LeftHeader?</th> <td>data1</td> <td>data2</td></tr> </table>

• Hibernate is performing unwanted SELECTs on call to saveOrUpdate

  - by digiarnie

  Let's say I have a House entity which maps to many Person entities. I then load an existing House which has 20 occupants. beginTransaction(); House house = houseDao.find(1L); commitTransaction(); Later in the code, I can then add a new Person to the House: ... List<Person> people = house.getPeople(); people.add(new Person("Dilbert")); .... When I make the call: session.saveOrUpdate(house); Hibernate performs 21 queries: 1 to SELECT the House and 20 to SELECT each existing Person in the House. I'm sure it's a small issue on my part, however, what should I do so that I can add a new Person to the house without having such a heavy hit on the database in this situation? This is all done within the same session.
