• Loading Fact Table + Lookup / UnionAll for SK lookups.

  - by Nev_Rahd

  I got to populate FactTable with 12 lookups to dimension table to get SK's, of which 6 are to different Dim Tables and rest 6 are lookup to same DimTable (type II) doing lookup to same natural key. Ex: PrimeObjectID = lookup to DimObject.ObjectID = get ObjectSK and got other columns which does same OtherObjectID1 = lookup to DimObject.ObjectID = get ObjectSK OtherObjectID2 = lookup to DimObject.ObjectID = get ObjectSK OtherObjectID3 = lookup to DimObject.ObjectID = get ObjectSK OtherObjectID4 = lookup to DimObject.ObjectID = get ObjectSK OtherObjectID5 = lookup to DimObject.ObjectID = get ObjectSK for such multiple lookup how should go in my SSIS package. for now am using lookup / unionall foreach lookup. Is there a better way to this.

• Securing Plugin Data in WordPress From Access by Other Plugins?

  - by farinspace

  There probably is some solution to this, whether it involves code running on just the wordpress installation or a combination of a wordpress installation and a master server I am not sure yet, but please remember not to have tunnel vision and consider any and all possible solutions: The scenario is this: A WordPress plugin (plugin-A) that manages some sort of valuable data (something that the admin would not want stolen), lets say, lead data with user's name and email addresses, the plugin uses its own db tables. Other than the obvious (which is the admin installing plugin-B, not knowing its malicious intent), what is to prevent another WordPress plugin (plugin-B) from accessing plugin-A data or hacking plugin-A files to circumvent security.

• DbMetal chokes on repeated foreign key references in SQLite - any ideas?

  - by DanM

  I've been struggling to get DbMetal to process my SQLite database. I finally isolated the problem. It won't allow a table to have two foreign key references to the same column. For example, a SQLite database with these two tables will fail: CREATE TABLE Person ( Id INTEGER PRIMARY KEY, Name TEXT NOT NULL ); CREATE TABLE Match ( Id INTEGER PRIMARY KEY, WinnerPersonId INTEGER NOT NULL REFERENCES Person(Id), LoserPersonId INTEGER NOT NULL REFERENCES Person(Id) ); I get this error: DbMetal: Sequence contains more than one matching element If I get rid of the second foreign key reference, no error occurs. So, this works: CREATE TABLE Match ( Id INTEGER PRIMARY KEY, WinnerPersonId INTEGER NOT NULL REFERENCES Person(Id), LoserPersonId INTEGER NOT NULL ); But I really need both "person" columns to reference the person table. I submitted a bug report for this, but I could use a workaround in the meantime. Any ideas?

• LINQ to Entities and Business / Validation Rules

  - by Chris

  We have a requirement where we need to allow users to dynamically create custom reports that will run against our database and return sets of data. It would be something similar to this: http://www.marcuswhitworth.com/2009/12/dynamic-linq-with-expression-trees/ but would ultimately contain the ability to create more complicated logic. I believe LINQ to Entities might possibly allow us to do something like we're attempting to achieve. I should note that these reports are going to need to run against multiple tables. Can anyone point me in the right direction for something like this? Has anyone done anything similar with LINQ to Entities?

• Query to return internal details about stored function in MS-SQL database

  - by Anthony

  I have been given access to a ms-sql database that is currently used by 3rd party app. As such, I don't have any documentation on how that application stores the data or how it retrieves it. I can figure a few things out based on the names of various tables and the parameters that the user-defined functions takes and returns, but I'm still getting errors at every other turn. I was thinking that it would be really helpful if I could see what the stored functions were doing with the parameters given to return the output. Right now all I've been able to figure out is how to query for the input parameters and the output columns. Is there any built-in information_schema table that will expose what the function is doing between input and output?

• Java: Embedded Data Base

  - by Dmitry

  Hello! I want to create a desctop application with an embedded data base. Data base is JavaDB(Derby). I have connected a jar file derby.jar to my project. The problem is I don't understand how to register a driver to use this data base. It is said that I should use Class.forName("org.apache.derby.jdbc.EmbeddedDriver") But what if that was another data base and its driver was not in a java standart package? As you can see I'm confused with this. I want to know, how to use my connected derby.jar, how to work with its jdbc driver and how to create tables in a specified directory. Please, give as detailed answer, as you can. (I'm a dummy in this =)) )

• How do I chain forms in Access? (pass values between them)

  - by jeff porter

  Hello, I'm using Access 2007 and have a data model like this... Passenger - Bookings - Destinations So 1 Passenger can have Many Bookings, each for 1 Destinations. My problem... I can create a form to allow the entry of Passenger details, but I then want to add a NEXT button to take me to a form to enter the details of the Booking (i.e. just a simple drop list of the Destinations). I've added the NEXT button and it has the events of RunCommand SaveRecord OpenForm Destination_form BUT, I cant work out how to pass accross to the new form the primary key of the passenger that was just entered (PassengerID). I'd really like to have just one form, and that allow the entry of the Passenger details and the selection of a Destination, that then creates the entries in the 2 Tables (Passenger & Bookings), but I can't get that to work either. Can anyone help me out please? Thanks Jeff Porter

• Copy email to the clipboard with Outlook VBA

  - by Arlen Beiler

  How do I copy an email to the clipboard and then paste it into excel with the tables intact? I am using Outlook 2007 and I want to do the equivalent of "Click on email > Select All > Copy > Switch to Excel > Select Cell > Paste". I have the Excel Object Model pretty well figured out, but have no experience in Outlook other than the following code. Dim mapi As NameSpace Dim msg As Outlook.MailItem Set mapi = Outlook.Application.GetNamespace("MAPI") Set msg = mapi.Folders.Item(1).Folders.Item("Posteingang").Folders.Item(1).Folders.Item(7).Items.Item(526)

• Put logic behind generated LinqToSql fields

  - by boris callens

  In a database I use throughout several projects, there is a field that should actually be a boolean but is for reasons nobody can explain to me a field duplicated over two tables where one time it is a char ('Y'/'N') and one time an int (1/0). When I generate a datacontext with LinqToSql the fields off course gets these datatypes. It would be nice if I don't have to drag this stupid choice of datatype throughout the rest of my application. Is there a way to give the generated classes a little bit of logic that just return me return this.equals('Y'); and return this==1; Preferably without having to make an EXTRA field in my partial class. It would be a solution to give the generated field a totally different name that can only be accessed through the partial class and then generate the extra field with the original name with my custom logic in the partial class. I don't know how to alter the accesibility level in my generated class though.. Any suggestions?

• InvalidOperationException sequence contains more than one element even when only one element

  - by user310256

  I have three tables, tblCompany table, tblParts table and a link table between them tblLinkCompanyParts. Since tblLinkCompanyParts is a link table so the columns that it has are LinkCompanyPartID(primary key), CompanyID from tblCompany table and PartID from tblParts as foreign keys. I have tied them up in the dbml file. In code if I write LinkCompanyParts.Parts (where LinkCompanyParts is an object of the tblLinkCompanyParts type) to get to the corresponding Part object I get the "InvalidOperationException: Sequence constains more than one element". I have looked at the data in the database and there is only one Parts record associated with the LinkCompanyPartID. The stack trace reads like at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable`1 source) at System.Data.Linq.EntityRef`1.get_Entity() at ... I read about SingleOrDefault vs FirstOrDefault but since the link table should have a one-one mapping therefore I think SingleOrDefault should work and besides "SingleOrDefault" statement is being generated behind the scenes in the designer.cs file at the following line return this._Part.Entity; Any ideas?

• How to access a plugin model from a regular controller in PHP Cake 1.1

  - by Duncan

  Hopefully a simple question: I've a plugin which uses a set of tables (kb_items, kb_item_tags, etc). and I'd like to be able to access these models from another controller (say, my Pages controller), thus: class PagesController extends AppController{ function knowledgebase(){ $items = $this->KbItem->findAll(...); } } I am admittedly breaking the rules a little (by not placing this controller inside the knowledge base plugin), but this in this case its a custom page that doesn't need to be part of the knowledge base plugin code base. Please let me know if you need more details. Thanks in advance for any help!

• "lock request time out period exceeded" Error When Trying to See DB Hierarchies

  - by Lloyd Banks

  I have a DB that I can run basic queries (albeit much slower than normal) off of. When I try to see the hierarchy trees for tables, views, or procedures in SSMS Object Explorer, I get the "lock request time out period exceeded". My Report Server reports that run off of objects in this DB are no longer completing. Jobs associated with procedures stored on this DB also do not run. I tried using sp_who2 to find and kill all connections on the DB. This has not solved the problem. What is going on here? How can I resolve this?

• How do I create a SQL Server 2008 Reporting Services Template to a Default Font?

  - by David Stein

  I'm creating a new template to create reports from at a later date. I know how to create one, and I know where to save it. However, the problem is this. Everything that is created on the report uses the default font of Arial with a size of 10pt. I need to set mine to default to Tahoma 11pt. I can create a mock title, mock tables, etc and save those to Tahoma 11pt, but any new controls that are used on any version of this report will default back to Arial 10pt. How do I fix this?

• Best practices for extending third party databases?

  - by Eric Watkins

  I have a situation where our developers extended a Third party database (MS SQL) by adding tables, views, stored procedures, and functions. Recently when the vender issued updates to the database they dropped all of our custom objects. The question now is what are some best practices that will allow us to extend the third party database but keep our objects safe from future updates? My first thought is to create a separate database but then I’m stuck with fully qualifying all the references back to the original database which may cause issues promoting database changes from test to production.

• How to force asp.net GridView control to wrap first row within <thead> </thead> tags

  - by burak ozdogan

  Hi, I want to use Christian Bach's tableSorter client-side table sorting jQuery plugin with my asp.Net GridView control. But the problem is, in the documentation it writes: tablesorter works on standard HTML tables. You must include THEAD and TBODY tags: And unfortunately asp.net renders my GridView only with tags and header row stays within as the 1st row. I have tried: dgvRate.HeaderRow.TableSection = TableRowSection.TableHeader; after calling .DataBind(); It only helped to have <TH></TH> within the header . But still everything is inside <tbody> Can I accomplish this, I mean moving my 1st row from <tbody></tbody> to <thead></thead> ? I do not want to add it manually on PreRender stage; I am sure this could be handled much simpler, isn't it? thanks

• Formatting a query to enumerate through 2 different datatables

  - by boiler1974

  I have 2 datatables sendTable and recvTable They both have identical column names and numbers of columns "NODE" "DSP Name" "BUS" "IDENT" "STATION" "REF1" "REF2" "REF3" "REF4" "REF5" "REF6" "REF7" "REF8" I need to compare these 2 tables and separate out the mismatches I only need to check Columns 3-11 and Ignore col 1 and 2 I tried at first removing the 2 columns and then loop thru row by row and return matches and mismatches but the problem with this approach is that I no longer have the "NODE" and "DSP Name" associated with the row when I finalize my results So I need help with a query Here is my attempt var samerecordQuery = from r1 in sendTable.AsEnumerable() where r1.Field<int>("BUS").Equals(from r2 in recvTable.AsEnumerable() where r2.Field<int>("BUS")) this obviously doesn't work so how do I format the query to say from r1 cols[3-11] equals r2 cols [3-11] and once I have this I can use the except to pull out the mismatches

• SSIS - Can I get the column schema for a flat file source from a database?

  - by Steve Clement

  We receive a nightly data export from a vendor in the form of about 10 tab-delimited flat file without column headers. In addition, the vendor provides us with the SQL scripts for the database tables so that we can import the files into our system. Unfortunately, the vendor recently changed the schema for the flat files. Each file has upwards 150 columns, and having to go through the DB schema and adjust column types on a Flat File Data Source in SSIS is extremely time consuming, not to mention a royal pain. Since I know the file data layout in the database schema, is there any way I can dynamically pull that into a Flat File source to set the columns correctly? Or am I just stuck with manually setting everything?

• QuestionOrAnswer model?

  - by Mark

  My site has Listings. Users can ask Questions about listings, and the author of the listing can respond with an Answer. However, the Answer might need clarification, so I've made them recursive (you can "answer" an answer). So how do I set up the database? The way I have it now looks like this (in Django-style models): class QuestionOrAnswer(Model): user = ForeignKey(User, related_name='questions') listing = ForeignKey(Listing, related_name='questions') parent = models.ForeignKey('self', null=True, blank=True, related_name='children') message = TextField() But what bugs me is that listing is now an attribute of the answers as well (it doesn't need to be). What happens if the database gets mangled and an answer belongs to a different listing than its parent question? That just doesn't make any sense. We can separate it with polymorphism: QuestionOrAnswer user message created updated Question(QuestionOrAnswer) shipment Answer(QuestionOrAnswer) parent = ForeignKey(QuestionOrAnswer) And that ought to work, but now ever question and answer is split into 2 tables. Is it worth this overhead for clearly defined models?

• Using a temp table in a view

  - by Dave

  Hi Everyone I would really like to create a view. I know you can't use temp tables in MSSQL2005 views. Without rewriting the sql, is there anything obvious I've missed? Backup plan is to use a stored proc. Cheers select * into #temp from vwIncidents SELECT vwIncidents.incidentcode, employeecode, EMPOS.POS_L4_CDA as areaAtTimeOfIncident into #temp1 FROM vwIncidents INNER JOIN EMPOS ON vwIncidents.employeecode = EMPOS.DET_NUMBERA WHERE EMPOS.POS_STARTC < vwIncidents.incidentdate AND (EMPOS.POS_ENDD > vwIncidents.incidentdate OR EMPOS.POS_ENDD IS NULL) order by incidentcode select #temp.*, #temp1.areaAtTimeOfIncident from #temp left outer join #temp1 on #temp.incidentcode = #temp1.incidentcode and #temp.employeecode = #temp1.employeecode order by incidentcode

• SQL Server Agent 2005 job runs but no output

  - by alimack

  Essentially I have a job which runs in BIDS and as as a stand lone package and while it runs under the SQL Server Agent it doesn't complete properly (no error messages though). The job steps are: 1) Delete all rows from table; 2) Use For each loop to fill up table from Excel spreasheets; 3) Clean up table. I've tried this [MS page][1] (steps 1 & 2), didn't see any need to start changing from Server side security. Also SQLServerCentral.com for [this page][2], no resolution. How can I get error logging or a fix? Note I've reposted this from Server Fault as it's one of those questions that's not pure admin or programming. I have logged in as the proxy account I'm running this under, and the job runs stand alone but complains that the Excel tables are empty?

• ASP.net MVC3 entities, don't know how to count

  - by Spedax

  I have 2 tables, 1 with countries, 1 with states. The states table has a column with Population. I'm using entities and I have created a List of states for the countries public class TblCountries { //Entities for my table country ... public List<tblStates> States { get; set; } } So now I can for example List all the states that belong to a country. Now what I want to do is count the population, so I can show the population that of an entire country. I tried using in my view @foreach (var item in Model.Countries) { @Html.DisplayFor(modelItem => item.States.Count<population>) } But this doesn't work, anyone know how to do this? Thanks in advanced!

• How to generate a user role grid

  - by Svish

  I have the following tables: users (id, username, ... ) roles (id, name) roles_users (user_id, role_id) I am wondering how I can create a nice sort of user-role-grid from that which an admin can use to administer roles to users in a clear way. What I would like is basically a table full of checkboxes sort of like this: Login Editor Admin Alice ¦ ¦ ¦ Bob ¦ ? ? Carol ¦ ¦ ? [Apply] Generating the table isn't too much of a deal, but I am very unsure how to handle it when it comes to how to name all the checkboxes and especially how to read and update the database in a not too clumsy way. Does anyone have any good advice or pointers on how to do this in a mostly clean way? I'm using the Kohana 3 framework, if there is anything there that can make this even easier, but I of course welcome any answer.
