  • TSQL, select values from large many-to-many relationship

    - by eugeneK
    I have two tables Publishers and Campaigns, both have similar many-to-many relationships with Countries,Regions,Languages and Categories. more info Publisher2Categories has publisherID and categoryID which are foreign keys to publisherID in Publishers and categoryID in Categories which are identity columns. On other side i have Campaigns2Categories with campaignID and categoryID columns which are foreign keys to campaignID in Campaigns and categoryID in Categories which again are identities. Same goes for Regions, Languages and Countries relationships I pass to query certain publisherID and want to get campaignIDs of Campaigns that have at least one equal to Publisher value from regions, countries, language or categories thanks

  • Duplicate a database record with linq

    - by holz
    Is there a way to duplicate a db record with linq to sql in c#? Id [int] IDENTITY(1,1) NOT NULL PRIMARY KEY, [Foo] [nvarchar](255) NOT NULL, [Bar] [numeric](28,12) NOT NULL, ... Given the table above, I would like to duplicate a record (but give it a different id), in a way that new fields added to the DB and the Linq dbml file at a later date will still get duplicated with out having to change that code that duplicates the record. ie I don't want to write newRecord.Foo = currentRecord.Foo; for all of the fields on the table.

  • Inheritance in tables - structure problem

    - by Naor
    I have 3 types of users in my system. each type has different information I created the following tables: BaseUser(base_user_id, username, password, additional common data) base_user_id is PK and Identity UserType1(user_id, data related to type1 only) user_id is PK and FK to base_user_id UserType2(user_id, data related to type2 only) user_id is PK and FK to base_user_id UserType3(user_id, data related to type3 only) user_id is PK and FK to base_user_id Now I have relation from each type of user to warehouses table. Users from type1 and type2 should have only warehouse_id and users from type3 should have warehouse_id and customer_id. I thought about this structure: WarehouseOfUser(base_user_id,warehouse_id) base_user_id is FK to base_user_id in BaseUser WarehouseOfTyp3User(base_user_id,warehouse_id, customer_id) base_user_id is FK to base_user_id in BaseUser The problem is that such structure allows 2 things I want to prevent: 1. add to WarehouseOfTyp3User data of user from type2 or type1. 2. add to WarehouseOfUser data of user from type3. what is the best structure for such case?

  • About SQL Server security

    - by Felipe Fiali
    I have an ASP.NET application which runs under the Classic .NET AppPool in IIS. I have a report to render from my website. The problem is SQL Server keeps telling me that it failed to create a connection to the datasource, because login failed for user IUSR. After adding that user directly to the databse I could get the report to work, but I'm concerned about security. By doing that, am I opening my specified databases to all websites hosted on IIS? Or is that account identity-specific?

  • How to whitelist a domain while blocking forgeries using that domain?

    - by QuantumMechanic
    How do you deal with the case of: wanting to whitelist a domain so that emails from it won't get eaten, but not having emails forged to appear to be from that domain get bogusly whitelisted whitelist_from_recvd looks promising, but then you have to know at least the TLD of every host that could send you mail from that domain. Often RandomBigCompany.com will outsource email to one or more sending companies (like Constant Contact and the like) in addition to using servers that reverse-resolve to something in its own domain. But it looks like whitelist_from_recvd can only map to one sending server pattern so that would be problematic. Is there a way to say something like "if email is from domain X, subtract N points from the spam score"? The idea would be that if the mail is legit, that -N will all but guarantee it isn't considered spam. But if it is spam, hopefully all the other failed tests will render it spam even with the -N being included.

  • Visual Studio 2010 Graphic Artifacts

    - by jonathan
    This problem started happening to me once I installed SP1 onto my Windows 7 Ultimate install. When changing between tabs, or even just hovering my mouse over buttons, VS2010 starts artifacting. It's bad enough where I often times can't see any of the code I'm working on. Sometimes just the button the mouse is over will go black, and other times the entire code panel will turn a black and grey pattern. This problem only happens with Visual Studio 2010 (2008 works fine). The problem remained when I upgraded Visual Studio to SP1. I've also uninstalled and reinstalled Visual Studio and the graphics drivers several times now, and I'm about ready to reinstall Windows 7, but I figured I'd ask for suggestions first. Google, as well as searching through Stack Exchange, did not turn up anything useful.

  • Google Maps KML Solution Validation

    - by user728584
    Google Maps newbie (GIS newbie), I'm looking at a solution to map an overlay (number of polygons) on-top of Google maps and wondered if using a KML file was a viable solution? Basically, I have a number of address (address data) that I will pass to our internal GIS system, the GIS system hands me back a KML file (one file with a number of different locations) and then I draw the polygon using the KML Layering options: https://developers.google.com/maps/documentation/javascript/layers Sound like a viable solution? Cheers

  • K-means algorithm variation with minimum measure of size

    - by user1464628
    I'm looking for some algorithm such as k-means for grouping points on a map into a fixed number of groups, by distance. The number of groups has already been decided, but the trick part (at least for me) is to meet the criteria that the sum of MOS of each group should in the certain range, say bigger than 1. Is there any way to make that happen? ID MOS X Y 1 0.47 39.27846 -76.77101 2 0.43 39.22704 -76.70272 3 1.48 39.24719 -76.68485 4 0.15 39.25172 -76.69729 5 0.09 39.24341 -76.69884

  • Outlook Replies with Inline Comments

    - by BillN
    I have a user who uses Word as his e-mail editor. Often when replying to an e-mail, he'll insert his comments into the body of the original e-mail. Since he is using Word as the editor, these show as [User Name] Comment Text in a contrasting color. However, some users see the comments in their Outlook, and others do not. I've tried Selecting/DeSelecting Word as the e-mail editor on the recipients, and it does not seem to make a difference. We are using Exchange 2007 with Outlook 2003 and Outlook 2007 clients along with a few Entourage Clients. There does not seem to be a pattern related to which client is used, but Entourage seems to be more likely to have the problem. TIA, Bill

  • How can I change the color of a Google Maps marker?

    - by abeger
    I'm using the Google Maps API to build a map full of markers, but I want one marker to stand out from the others. The simplest thing to do, I think, would be to change the color of the marker to blue, instead of red. Is this a simple thing to do or do I have to create a whole new icon somehow? If I do have to create a new icon, what's the easiest way to do that?

  • Is there any restriction in generating the maximum number of keys for google maps

    - by Aruna
    Hi , I have generated a Google map key by login as a [email protected] . Is there any restriction in generating the number of keys for each user. Since we have 2 different domains and i need to generate key for that too. Actually i am not sure about of how many keys the person who used this id has created.. And is there any way to find of how many keys had already been created for the same account previously???

  • Selecting based on __key__ (a unique identifier) in google appengine [Java]

    - by Stavros
    I have public class QuantityType { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; @Persistent private String type; } I am trying to setup a query to get the right QuantityType by it's key gql = "select * from QuantityType where __key__='aght52oobW1hIHTWVzc2FnZRiyAQw'"; But its not working because BadFilterError: BadFilterError: invalid filter: key filter value must be a Key; received aght52oobW1hIHTWVzc2FnZRiyAQw (a str). I have also tried to use gql = "select * from QuantityType where __key__=='" + KeyFactory.stringToKey(qTypeKey)+"'"; but it's now working.. How can I get a specific object from my datastore by it's key?

  • How do you learn a class hierarchy quickly?

    - by rsteckly
    Hi, Something I don't enjoy about programming is learning a new API. For example, right now I'm trying to learn Windows Identity Foundation. Its frustrating because I'm going to spend the bulk of the time learning how a few classes work and actually only write several lines of code. In .NET, there are so many types that I seem to spend more time hunting around in msdn for a class than writing code. It also interrupts my workflow while I'm working because I have to type a little bit than look something up. Obviously, I don't have to do this for the basic classes. Whenever new things come though there is definitely some looking up to do. Then I often don't reuse that class enough to really review it or bring it into action. I'm wondering if anybody out there has a found a way to memorize (or look up more efficiently) these object model hierarchies?

  • Using the MongoDB Ruby driver in Rails? (without an object mapper)

    - by Mark L
    I have recently been getting my feet wet in MongoDB using Mongoid w/ Rails 3, but I'm now interested in learning the low level MongoDB features using only the Ruby driver, and trying some map/reduce that would not be possible through Mongoid (afaik) I'm not entirely sure where in Rails I should be setting up the db connections etc, and any pointers would be much appreciated!

  • Error: Too Many Arguments Specified when Inserting Values from ASP.NET to SQL Server

    - by SidC
    Good Afternoon All, I have a wizard control that contains 20 textboxes for part numbers and another 20 for quantities. I want the part numbers and quantities loaded into the following table: USE [Diel_inventory] GO /****** Object: Table [dbo].[QUOTEDETAILPARTS] Script Date: 05/09/2010 16:26:54 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[QUOTEDETAILPARTS]( [QuoteDetailPartID] [int] IDENTITY(1,1) NOT NULL, [QuoteDetailID] [int] NOT NULL, [PartNumber] [float] NULL, [Quantity] [int] NULL, CONSTRAINT [pkQuoteDetailPartID] PRIMARY KEY CLUSTERED ( [QuoteDetailPartID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[QUOTEDETAILPARTS] WITH CHECK ADD CONSTRAINT [fkQuoteDetailID] FOREIGN KEY([QuoteDetailID]) REFERENCES [dbo].[QUOTEDETAIL] ([ID]) ON UPDATE CASCADE ON DELETE CASCADE GO Here's the snippet from my sproc for this insert: set @ID=scope_identity() Insert into dbo.QuoteDetailParts (QuoteDetailPartID, QuoteDetailID, PartNumber, Quantity) values (@ID, @QuoteDetailPartID, @PartNumber, @Quantity) When I run the ASPX page, I receive an error that there are too many arguments specified for my stored procedure. I understand why I'm getting the error, given the above table layout. However, I need help in structuring my insert syntax to look for values in all 20 PartNumber and Quantity field pairs. Thanks, Sid

  • SQLite DB borked when opened on a different machine

    - by pruefsumme
    Hello, I'm using SQLite to store some data. The primary database is on a NAS (Debian Lenny, 2.6.15, armv4l) since the NAS runs a script which updates the data every day. A typical "select * from tableX" looks like this: 2010-12-28|20|62.09|25170.0 2010-12-28|21|49.28|23305.7 2010-12-28|22|48.51|22051.1 2010-12-28|23|47.17|21809.9 When I copy the DB to my main computer (Mac OS X) and run the same SQL query, the output is: 2010-12-28|20|1.08115035175016e-160|25170.0 2010-12-28|21|2.39343503830763e-259|-9.25596535779558e+61 2010-12-28|22|-1.02951149572792e-86|1.90359837597183e+185 2010-12-28|23|-1.10707273937033e-234|-2.35343828462275e-185 The 3rd and 4th column have the type REAL. Interesting fact: When the numbers are integer (i.e. they end with ".0"), there is no difference between the two databases. In all other cases, the differences are ... hm ... surprising? I can't seem to find a pattern. If someone's got a clue - please share!

  • How can I find the size of Flash and RAM used by a firmware?

    - by Asad
    Hi Fellas, Please help me in finding the size of Flash (ROM) and RAM used by the firmware. The firmware is implemented using C++. Also I have Keil microvision4, will it be helpful to find the ROM and RAM size? Or do I need to look at the MAP(.M51) file of the firmware to find the memory sizes? Or is just looking at the size of hex files (.hex) enough for locating the size of ROM? Please suggest!

  • Deleting file in Samba doesn't delete file?

    - by Jeff Welling
    Why, when I delete some files in Samba, does it not delete them but instead merely change their filename from filename.txt to ._filename.txt? This is not the behaviour one would expect when "deleting" a file, so I'm wondering if there's an option I forgot to set somewhere in the samba config. It does this to some files but not to others, I have not yet spotted a pattern to its choosiness. There is a Ubuntu 12.04 machine and a Mac OS X machine which have write (and thus delete) capability, no Windows machines have write permission.
