  • The table/view 'TABLE1' does not have a primary key defined and no valid primary key could be inferr

    - by Nickson
    I get the following error message The table/view 'TABLE1' does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity you will need to review your schema, add the correct keys and uncomment it when I try to add a view to an Entity Data Model. For testing, I have created a very simple view and I still get the error. below is the view definition SELECT DISTINCT TOP (100) PERCENT MIN(id) AS Expr4, MIN(EmpNo) AS Expr1, MIN(Name) AS Expr2, MIN(Category) AS Expr3 FROM dbo.MYView1 GROUP BY id does any one know of a simple work around. I have looked at this thread http://stackoverflow.com/questions/745341/can-ms-sql-views-have-primary-and-foriegn-keys but in my scenario, what is recommended is not applicable. If I could only have the view added to the Model.

  • Entity Framework - An object with the same key already exists in the ObjectStateManager

    - by Justin
    Hey all, I'm trying to update a detached entity in .NET 4 EF: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Save(Developer developer) { developer.UpdateDate = DateTime.Now; if (developer.DeveloperID == 0) {//inserting new developer. DataContext.DeveloperData.Insert(developer); } else {//attaching existing developer. DataContext.DeveloperData.Attach(developer); } //save changes. DataContext.SaveChanges(); //redirect to developer list. return RedirectToAction("Index"); } public static void Attach(Developer developer) { var d = new Developer { DeveloperID = developer.DeveloperID }; db.Developers.Attach(d); db.Developers.ApplyCurrentValues(developer); } However, this gives the following error: An object with the same key already exists in the ObjectStateManager. The ObjectStateManager cannot track multiple objects with the same key. Anyone know what I'm missing? Thanks, Justin

I have not found anything in the Web. Thanks in advance.

  • Spring JdbcTemplate - Insert blob and return generated key

    - by itsadok
    From the Spring JDBC documentation, I know how to insert a blob using JdbcTemplate final File blobIn = new File("spring2004.jpg"); final InputStream blobIs = new FileInputStream(blobIn); jdbcTemplate.execute( "INSERT INTO lob_table (id, a_blob) VALUES (?, ?)", new AbstractLobCreatingPreparedStatementCallback(lobhandler) { protected void setValues(PreparedStatement ps, LobCreator lobCreator) throws SQLException { ps.setLong(1, 1L); lobCreator.setBlobAsBinaryStream(ps, 2, blobIs, (int)blobIn.length()); } } ); blobIs.close(); And also how to retrieve the generated key of a newly inserted row: KeyHolder keyHolder = new GeneratedKeyHolder(); jdbcTemplate.update( new PreparedStatementCreator() { public PreparedStatement createPreparedStatement(Connection connection) throws SQLException { PreparedStatement ps = connection.prepareStatement(INSERT_SQL, new String[] {"id"}); ps.setString(1, name); return ps; } }, keyHolder); // keyHolder.getKey() now contains the generated key Is there a way I could combine the two?

  • Map external directory to web.xml

    - by prometheus
    Is there an easy way to map a directory in the web.xml or other deployment descriptor (jetty.xml, etc) files? For example, if I have a directory /opt/files/ is there a way that I can access its files and sub-directories by visiting http://localhost/some-mapping/? It strikes me that there should be some simple way of doing this, but I haven't been able to find out how (via google, stackoverflow, etc). All I've found are servlets that mimic fileservers, which is not what I would like. For reference I am using jetty on an AIX box.

  • ASP.NET MVC model binding foreign key relationship

    - by Rory Fitzpatrick
    Is it possible to bind a foreign key relationship on my model to a form input? Say I have a one-to-many relationship between Car and Manufacturer. I want to have a form for updating Car that includes a select input for setting Manufacturer. I was hoping to be able to do this using the built-in model binding, but I'm starting to think I'll have to do it myself. My action method signature looks like this: public JsonResult Save(int id, [Bind(Include="Name, Description, Manufacturer")]Car car) The form posts the values Name, Description and Manufacturer, where Manufacturer is a primary key of type int. Name and Description get set properly, but not Manufacturer, which makes sense since the model binder has no idea what the PK field is. Does that mean I would have to write a custom IModelBinder that it aware of this? I'm not sure how that would work since my data access repositories are loaded through an IoC container on each Controller constructor.

  • C#: Accessing a Dictionary.Keys Key through a numeric index

    - by Michael Stum
    I'm using a Dictionary<string, int> where the int is a count of the key. Now, I need to access the last-inserted Key inside the Dictionary, but i do not know the name of it. The obvious attempt: int LastCount = mydict[mydict.keys[mydict.keys.Count]]; does not work, because Dictionary.Keys does not implement a []-indexer. I just wonder if there is any similar class? I thought about using a Stack, but that only stores a string. I could now create my own struct and then use a Stack<MyStruct>, but I wonder if there is another alternative, essentially a Dictionary that implements an []-indexer on the Keys?

  • Serializing a list of Key/Value pairs to XML

    - by Slauma
    I have a list of key/value pairs I'd like to store in and retrieve from a XML file. So this task is similar as described here. I am trying to follow the advice in the marked answer (using a KeyValuePair and a XmlSerializer) but I don't get it working. What I have so far is a "Settings" class ... public class Settings { public int simpleValue; public List<KeyValuePair<string, int>> list; } ... an instance of this class ... Settings aSettings = new Settings(); aSettings.simpleValue = 2; aSettings.list = new List<KeyValuePair<string, int>>(); aSettings.list.Add(new KeyValuePair<string, int>("m1", 1)); aSettings.list.Add(new KeyValuePair<string, int>("m2", 2)); ... and the following code to write that instance to a XML file: XmlSerializer serializer = new XmlSerializer(typeof(Settings)); TextWriter writer = new StreamWriter("c:\\testfile.xml"); serializer.Serialize(writer, aSettings); writer.Close(); The resulting file is: <?xml version="1.0" encoding="utf-8"?> <Settings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <simpleValue>2</simpleValue> <list> <KeyValuePairOfStringInt32 /> <KeyValuePairOfStringInt32 /> </list> </Settings> So neither key nor value of the pairs in my list are stored though the number of elements is correct. Obviously I am doing something basically wrong. My questions are: How can I store the key/value pairs of the list in the file? How can I change the default generated name "KeyValuePairOfStringInt32" of the elements in the list to some other name like "listElement" I'd like to have?

  • Cross-platform embedded database/key-value store for C#

    - by Arne Claassen
    I'm looking for a fast, embeddable key/value store with cursor semantics over key collections (or a simple embeddable DB) that I can use in .NET and mono. Need it to be open-source, would prefer an MIT or Apache style license over a GPL license. Not opposed to a library that needs bindings to be written, as long as binaries are available for both windows and linux. Options considered: SQLite - has bindings and native implementation, but single-threaded and not all that fast Embedded InnoDB - no .NET bindings i can find and it's GPLv2 Berkley DB - no .NET bindings i can find Tokyo Cabinet - no .NET bindings i can find and problematic to build on windows MadCow Memory-mapped data structures - GPLv2 Is there an option better than the above that i'm missing, or bindings for the above i don't know about?

  • ETL Operation - Return Primary Key

    - by user302254
    I am using Talend to populate a data warehouse. My job is writing customer data to a dimension table and transaction data to the fact table. The surrogate key (p_key) on the fact table is auto-incrementing. When I insert a new customer, I need my fact table to reflect the id of the related customer. As I mentioned my p_key is auto auto_incrementing so I can't just insert an arbitrary value for the p_key. Any thought on how I can insert a row into my dimension table and still retrieve the primary key to reference in my fact record? Thanks.

  • Add 2 values to 1 key in a PHP array

    - by Mike Munroe
    I have a result set of data that I want to write to an array in php. Here is my sample data: **Name** **Abbrev** Mike M Tom T Jim J Using that data, I want to create an array in php that is of the following: 1|Mike|M 2|Tom|T 3|Jim|j I tried array_push($values, 'name', 'abbreviation') [pseudo code], which gave me the following: 1|Mike 2|M 3|Tom 4|T 5|Jim 6|J I need to do a look up against this array to get the same key value, if I look up "Mike" or "M". What is the best way to write my result set into an array as set above where name and abbreviation share the same key?

  • Best approach to convert XML to RDF/XML using an ontology

    - by krisvandenbergh
    I have an XML which uses the XPDL standard (which has an XML schema). What I'm trying to do now is to convert its content to RDF format (serialized in XML), in terms of a certain ontology. Clearly, there needs to be some sort of mapping here. I would like to do this using PHP. The thing is, I have no idea how to do this best. I know how to read an XML file, but how would the mappings occur? What would be a good approach?

  • Using NHibernate with an EAV data model

    - by devonlazarus
    I'm trying to leverage NH to map to a data model that is a loose interpretation of the EAV/CR data model. I have most of it working but am struggling with mapping the Entity.Attributes collection. Here are the tables in question: -------------------- | Entities | -------------------- | EntityId PK |-| | EntityType | | -------------------- | ------------- | V -------------------- | EntityAttributes | ------------------ --------------------------- -------------------- | Attributes | | StringAttributes | | EntityId PK,FK | ------------------ --------------------------- | AttributeId FK | -> | AttributeId PK | -> | StringAttributeId PK,FK | | AttributeValue | | AttributeType | | AttributeName | -------------------- ------------------ --------------------------- The AttributeValue column is implemented as an sql_variant column and I've implemented an NHibernate.UserTypes.IUserType for it. I can create an EntityAttribute entity and persist it directly so that part of the hierarchy is working. I'm just not sure how to map the EntityAttributes collection to the Entity entity. Note the EntityAttributes table could (and does) contain multiple rows for a given EntityId/AttributeId combination: EntityId AttributeId AttributeValue -------- ----------- -------------- 1 1 Blue 1 1 Green StringAttributes row looks like this for this example: StringAttributeId AttributeName ----------------- -------------- 1 FavoriteColor How can I effectively map this data model to my Entity domain such that Entity.Attributes("FavoriteColors") returns a collection of favorite colors? Typed as System.String?

  • Handle tab key in ToolStripComboBox

    - by Jiri
    Hi, I have a ToolStripComboBox in a ToolStrip, and when I press TAB key in it, it gives focus to the next toolstrip button. I would like to change this behavior and give focus to a richtextbox on my form instead. The problem is that ToolStripComboBox does not have PreviewKeyDown event. And PreviewKeyDown of the hosting ToolStrip Toolbar is not called when tab key is pressed in the combo (just when pressed and some toolstripbutton is focused). TabStop of the toolstrip toolbar is false. Any ideas?

  • Active Merchant Paypal Recurring Pem Error Neither Pub Nor Priv Key

    - by Andy
    Hi, I am trying to use ActiveMerchant to make a Paypal Recurring transaction call. I used the patch here: http://blog.vuzit.com/2008/08/01/paypal-website-payments-pro-us-with-recurring-billing-and-activemerchant/ and I'm stuck on this here: ActiveMerchant::Billing::PaypalGateway.pem_file = File.read('paypal_cert.pem') I am fairly sure the pem file is correctly downloaded from paypal. The error I receive is: /Library/Ruby/Gems/1.8/gems/activemerchant-1.5.1/lib/active_merchant/lib/connection.rb:129:in initialize': Neither PUB key nor PRIV key:: nested asn1 error (OpenSSL::PKey::RSAError) from /Library/Ruby/Gems/1.8/gems/activemerchant-1.5.1/lib/active_merchant/lib/connection.rb:129:innew' from calling the commit method from line 49 of paypal_pro_recurring. I simply have 2 files - paypal_pro_recurring.rb from the tutorial and paypalTest.rb which I wrote and simply requires all files and calls the function. I hope the error isn't something stupid like I must require from an environment file or something. Thanks all!

  • Two Key HashSet?

    - by athena
    I need a HashSet implementation where the elements are a pair of Integers eg. Set s = { {1,2} , {3,4} , {1,4}}. Here the set s has 3 elements. This kind of two key HashSet is needed in many situations like, I have a relation in my database where the candidate key is a combination of two columns. Is there some library which already provides this? If no such implementation is available, then rather then implementing the entire data structure from scratch, will it be easier (and efficient?) to extend the HashSet implementation in Java?

  • fourier transform to transpose key of a wav file

    - by tbischel
    I want to write an app to transpose the key a wav file plays in (for fun, I know there are apps that already do this)... my main understanding of how this might be accomplished is to 1) chop the audio file into very small blocks (say 1/10 a second) 2) run an FFT on each block 3) phase shift the frequency space up or down depending on what key I want 4) use an inverse FFT to return each block to the time domain 5) glue all the blocks together But now I'm wondering if the transformed blocks would no longer be continuous when I try to glue them back together. Are there ideas how I should do this to guarantee continuity, or am I just worrying about nothing?

  • How to map IDictionary<string, object> in Fluent NHibernate?

    - by user298221
    I am looking to persist user preferences into a collection of name value pairs, where the value may be an int, bool, or string. There are a few ways to skin this cat, but the most convenient method I can think of is something like this: public class User { public virtual IDictionary<string, object> Preferences { get; set; } } with its usage as: user.Preferences["preference1"] = "some value"; user.Preferences["preference2"] = 10; user.Preferences["preference3"] = true; var pref = (int)user.Preferences["preference2"]; I'm not sure how to map this in Fluent NHibernate, though I do think it is possible. Generally, you would map a simpler Dictionary<string, string> as: HasMany(x => x.Preferences) .Table("Preferences") .AsMap("preferenceName") .Element("preferenceValue"); But with a type of 'object', NHibernate doesn't know how to deal with it. I imagine a custom UserType could be created that breaks an 'object' down to a string representing its Type and a string representing the value. We would have a table that looks kind of like this: Table Preferences userId (int) preferenceName (varchar) preferenceValue (varchar) preferenceValueType (varchar) and the hibernate mapping would like this: <map name="Preferences" table="Preferences"> <key column="userId"></key> <index column="preferenceName" type="String" /> <element type="ObjectAsStringUserType, Assembly"> <column name="preferenceValue" /> <column name="preferenceValueType"/> </element> </map> I'm not sure how you would map this in Fluent NHibernate. Maybe there's a better way to do this, or maybe I should just suck it up and use IDictionary<string, string>. Any ideas?

  • inno setup - registry key vs. .ini files

    - by PPTim
    Hi, Dabbling with creating an installer with inno setup- but wondering: What are the pros and cons of using registry keys (windows program) vs. .ini files that sit within the program folder? If I store all my user settings in .ini files, the entire program can be removed by deleting the folder. With registry keys i'd have to create an uninstaller / remove the key manually. Why is it that most commercial applications use registry values? I know from brief use of Macs that most programs are drag and drop. Are one of the major reasons because of the lack of a registry key in mac OS?

  • Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key"

    - by Michael Rosario
    Hello world. Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key" scheme? Problem facts: I am using Oracle XE. I have implemented the following table and trigger: CREATE TABLE "USERS" ( "ID" NUMBER(38,0), "USER_NAME" VARCHAR2(50), "PASSWORD" VARCHAR2(50), "EMAIL" VARCHAR2(100), CONSTRAINT "USERS_PK" PRIMARY KEY ("ID") ENABLE ) / CREATE OR REPLACE TRIGGER "BI_USERS" before insert on "USERS" for each row begin select "USERS_SEQ".nextval into :NEW.ID from dual; end; / ALTER TRIGGER "BI_USERS" ENABLE / MyGeneration / Doodads created the following stored proc... CREATE OR REPLACE PROCEDURE "XXX"."PI_USERS" ( p_ID IN USERS.ID%type, p_USER_NAME IN USERS.USER_NAME%type, p_PASSWORD IN USERS.PASSWORD%type, p_EMAIL IN USERS.EMAIL%type ) IS BEGIN INSERT INTO USERS ( ID, USER_NAME, PASSWORD, EMAIL ) VALUES ( p_ID, p_USER_NAME, p_PASSWORD, p_EMAIL ); END PI_USERS; The sequence and trigger combination is working fine. The BusinessEntity class in C# does not receive the new ID. Any recommended ways to allow the calling code receive the new record ID?

  • public key email encryption

    - by anatak
    Who has their email fully encrypted ? I would like to encrypt my email but I am not sure how to start. If I use encrypted email and I send an email to someone who does not encrypt his email how can the receiver read the email ? What email client would you recommend to run on a windows systems for encrypted email ? I am using Thunderbird at the moment. As I understand you have to generate 2 keys (one public and one private) but how do you generate this key? I also think that you have to put your key somewhere to download but I don't understand how you can trust the downloaded keys. Any links to a good (not too complicated) guide about the working an implementing of email encryption would be very much appreciated. kind regards wim hendrix anatak

  • D3.js binding an object to data and appending for each key

    - by frshca
    I'm a D3.js newbie and I'm learning how to play around with data. Let's say I have an object with names as keys, and each key has an array of numbers like this: var userdata = { 'John' : [0, 1, 3, 9, 8, 7], 'Harry': [0, 10, 7, 1, 1, 11], 'Steve': [3, 1, 4, 4, 4, 17], 'Adam' : [4, 77, 2, 13, 11, 13] }; For each user, I would like to append an SVG object and then plot the line with the array of values for that user. So here is my assumption of how that would look based on tutorials, but I know it is incorrect. This is to show my limited knowledge and give better understanding of what I'm doing: First I should create the line var line = d3.svg.line().interpolate('basis'); Then I want to bind the data to my body and append an svg element for each key: d3.select('body') .selectAll('svg') .data(userdata) .enter() .append('svg') .append(line) .x(function(d, i) { return i; }) .y(function(d) { return d[i]; }); So am I close??
