  • Can I make an identity field span multiple tables in SQL Server?

    - by johnnycakes
    Can I have an "identity" (unique, non-repeating) column span multiple tables? For example, let's say I have two tables: Books and Authors. Authors AuthorID AuthorName Books BookID BookTitle The BookID column and the AuthorID column are identity columns. I want the identity part to span both columns. So, if there is an AuthorID with a value of 123, then there cannot be a BookID with a value of 123. And vice versa. I hope that makes sense. Is this possible? Thanks. Why do I want to do this? I am writing an APS.NET MVC app. I am creating a comment section. Authors can have comments. Books can have comments. I want to be able to pass an entity ID (a book ID or an author ID) to an action and have the action pull up all the corresponding comments. The action won't care if it's a book or an author or whatever. Sound reasonable?

  • Using static strings to define input field names in JSPs - good idea or not?

    - by Derek Clarkson
    Hi all, I've just be asked to work on a large portal project and have been looking through the established code. I keep finding this in the jsps: <input class="portlet-form-button" name="<%=ModifyUserProfile.FORM_FIRST_TIME_LOGIN_SUBMIT%>" type="submit" ... The authors are using static strings defined in classes to define the names of input fields and buttons in jsp forms. I've never seen this done before and was wondering if this is common practice. I'm inclined to think not, but I'm asking because, apart from centralising names which I would have thought are not likely to change, I can't see the reason why. Any thoughts on this?

  • Why does my ASP.NET user control's field value reset to 0?

    - by Innogetics
    In the code below, why does the groupId value reset to 0 during Page_Load event? Maybe perhaps the AccountGrid created with groupId 1 is not the one that is loaded to the page? public partial class AccountGrid : System.Web.UI.UserControl { int groupId = 0; public AccountGrid() { } // an aspx page creates AccountGrid with "new AccountGrid(1)" public AccountGrid(int groupId) { this.groupId = groupId; } protected void Page_Load(object sender, EventArgs e) { DataAccessFacade facade = new DataAccessFacade(); // groupId resets to 0 here... grdAccount.DataSource = facade.GetAccountsByAccountGroupId(this.groupId); grdAccount.DataBind(); } } In my page, I have public partial class Default : System.Web.UI.Page { public Default() { } public void Page_Load(object sender, EventArgs e) { ctlAccountGrid = new Views.Controls.Account.AccountGrid(1); // should I do databind? ctlAccountGrid.DataBind(); } }

  • PHP/json My field names are being truncated to 30 characters. Can I stop this?

    - by Biff MaGriff
    Hi Everyone! Ok so I got this piece of vendor software that they said should be run on an apache php server and MySql database. I didn't have either of those so I put it on a PHP IIS server and I converted the code to work on SQL server. ex. mysql_select_db - mssql_select_db (among other things) So I have the following code in a php file $query = "SELECT * FROM TableName WHERE KEY_FIELD = '".$keyField."';"; $result = mssql_query($query); $arr = array(); while ( $obj = mssql_fetch_object($result) ) { $arr[] = $obj; } echo '{"results":'.json_encode($arr).'}'; and my results look something like this (captured with fiddler 2) {"results":[{"KEY_FIELD":"57", "My30characterlongfieldthatiscu":"GoodValue"}]} "My30characterlongfieldthatiscu" should be "My30characterlongfieldthatiscutoff" Kinda weird, no? The vendor claims that the app works perfectly on their end. I'm thinking this is some sort of IIS PHP limit, is there a way around it or can I expand it? I found this solution http://www.php.net/manual/en/ref.mssql.php#74834 but I don't understand it. Thanks!

  • Django admin: how do I add an unrelated model field to a model change/add page?

    - by NP
    I have the following models: class Foo(models.Model): field1 = models.IntegerField() ... class Bar(models.Model): field1 = models.IntegerField() ... class Foo_bar(models.Model): foo = models.ForeignKey(Foo) bar = models.ForeignKey(Bar) ... In the admin, I want it so that in the Foo change/add page, you can specify a Bar object, and on save I want to create a Foo_bar object to represent the relationship. How can I do this through customizing the Admin site/ModelAdmins? Thanks.

  • "Invalid use of Null" when using Str() with a Null Recordset field, but Str(Null) works fine

    - by Mike Spross
    I'm banging my head against the wall on this one. I was looking at some old database reporting code written in VB6 and case across this line (the code is moving data from a "source" database into a reporting database): rsTarget!VehYear = Trim(Str(rsSource!VehYear)) When rsSource!VehYear is Null, the above line generates an "Invalid use of Null" run-time error. If I break on the above line and type the following in the Immediate pane: ?rsSource!VehYear It outputs Null. Fine, that makes sense. Next, I try to reproduce the error: ?Str(rsSource!VehYear) I get an "Invalid use of Null" error. However, if I type the following into the Immediate window: ?Str(Null) I don't get an error. It simply outputs Null. If I repeat the same experiment with Trim() instead of Str(), everything works fine. ?Trim(rsSource!VehYear) returns Null, as does ?Trim(Null). No run-time errors. So, my question is, how can Str(rsSource!VehYear) possibly throw an "Invalid use of Null" error when Str(Null) does not, when I know that rsSource!VehYear is equal to Null?

  • What is the precision of the priority field in sitemap.xml?

    - by Christoph
    Unfortunately the specification does not tell anything about precision. The xml scheme definition states that it is of the type xsd:decimal: <xsd:restriction base="xsd:decimal"> <xsd:minInclusive value="0.0"/> <xsd:maxInclusive value="1.0"/> </xsd:restriction> I have a sitemap generator that uses up to 10 positions after decimal point. Where often only the last few positions differ. These numbers are perfectly right according to the xsd, but yet i found some pages(3,4) that state that only 0.0, 0.1, 0.2, .., 1.0 are valid values. How will the search engines react to such a sitemap? Will some just round the value? I know that it is unlikely that someone can provide an answer to that question, unless he works for that search engine, but i think experiences will also do.

  • How can I map to a field that is joined in via one of three possible tables

    - by Mongus Pong
    I have this object : public class Ledger { public virtual Person Client { get; set; } // .... } The Ledger table joins to the Person table via one of three possible tables : Bill, Receipt or Payment. So we have the following tables : Ledger LedgerID PK Bill BillID PK, LedgerID, ClientID Receipt ReceiptID PK, LedgerID, ClientID Payment PaymentID PK, LedgerID, ClientID If it was just the one table, I could map this as : Join ( "Bill", x => { x.ManyToOne ( ledger => ledger.Client, mapping => mapping.Column ( "ClientID" ) ); x.Key ( l => l.Column ( "LedgerID" ) ); } ); This won't work for three tables. For a start the Join performs an inner join. Since there will only ever be one of Bill, Receipt or Payment - an inner join on these tables will always return zero rows. Then it would need to know to do a Coalesce on the ClientID of each of these tables to know the ClientID to grab the data from. Is there a way to do this? Or am I asking too much of the mappings here?

  • How to add an additional field to a queryset?

    - by Mark
    I've got a list of affiliates (users who have referred someone to the site): affiliates = User.objects.annotate(referral_count=Count('referrals')).filter(referral_count__gt=0) And a count of the number of users each affiliate has referred within a time frame: new_users = User.objects.filter(date_joined__gt=sd, date_joined__lte=ed) new_referrals = User.objects.filter(referrals__user__in=new_users).annotate(referral_count=Count('referrals')) How can I do something like new_referrals['affiliate.username'].referral_count from within my template? Note that this is not just a syntax issue, I also need to index new_referrals somehow so that I'm able to do this. Either this, or if I can somehow add a new_referral_count to the first query, that'd work too.

  • Using MonoDroid, how can I open a dialog when an EditText field gains focus?

    - by Kiada
    I made the EditText clickable but you have to "double-click" to bring the dialog box up, which isn't really desired behaviour. How can I bring the dialog box up when the EditText is clicked / gains focus? Bonus points for including a way to stop the keyboard popping up :) _createProfileDobEdtTxt.Clickable = true; _createProfileDobEdtTxt.Click += (sender, e) => { ShowDialog(DATE_OF_BIRTH_DIALOG); };

  • Using SSIS, how do you read a datetime field into a variable that is of Data Type string?

    - by Mark Kadlec
    This one has bugged me for the longest time and a great question to ask the Stackoverflow users I think. I have a rather large SSIS flow that uses a string variable to store the datetime. I would now like to dynamically read the datetime value from the database, but how would you construct the SSIS to do this? My first obvious thought would be to simply execute a SQL task to get the datetime and store it in the variable, but got the "differs from the current variable type" error. Is there a simple way to convert the database datetime into a String variable? Any help from the community would be appreciated,

  • What FPGAs (Field-Programmable Gate Arrays) can one buy to experiment with at home?

    - by Joe Blow
    What the heck is an FPGA -- where can I buy one? What sort of system do you need to experiment with them? How to program them? Can you "load" if that's the right terms an FPGA using an ordinary mac or perhaps other *nix or windoze computer? Where can I buy some FPGAs today to experiment with ??! Are they expensive this only available to industry or can I buy one today? Does anyone know about this? Thanks! I have become interested in FPGAs after reading this question...

  • Can I concatenate multiple MySQL rows into one field?

    - by Dean
    Using MySQL, I can do something like select hobbies from peoples_hobbies where person_id = 5; and get: shopping fishing coding but instead I just want 1 row, 1 col: shopping, fishing, coding The reason is that I'm selecting multiple values from multiple tables, and after all the joins I've got a lot more rows than I'd like. I've looked for a function on MySQL Doc and it doesn't look like the CONCAT or CONCAT_WS functions accept result sets, so does anyone here know how to do this?

  • is there a way to show what field you updated in mysql?

    - by ggfan
    When users edit their account, I want to display a confirmation page that shows their updated information with the fields that they changed in bold. Is there a mysql statement that allows you to select the fields that a user changes? If not, how exactly can I achieve this Ex: (editaccount.php) first_name: bob last_name: builder email: [email protected] When they change say their first name to "james", the confirmation page shows their first name in bold because they changed that but the other areas are still normal text. first_name: <b>James</b> last_name: builder email: [email protected]

  • How can I delete ghost database field between a special date?

    - by Chiyou
    I have a mysql table with many user input and I want to delete ghost e-mail between a special date. I use this query and it seems to work very good: DELETE u1 From tx_table u1 JOIN tx_table u2 USING (email) WHERE u1.tstamp < u2.tstamp but I want to delete between a longer time. When I add 300 it seems to delete everything in my table: DELETE u1 From tx_table u1 JOIN tx_table u2 USING (email) WHERE u1.tstamp < u2.tstamp+300. How can I add 5 minutes to the tstamp with SQL?
