• Need a creative machine name suggestions for dev machine.

  - by Jay

  So.. I have a windows machine running a dev-db server (oracle) , svn server (visual svn) and a project management tool (redmine). I need suggestions for a good host name for this machine, which is very easy-to-remember and sounds creative. Would love to hear from your experiences, for inspiration :) Here is what is on my mind right now: (xyz being the project name) < xyz >forge < xyz >labs Need more on these lines. Thanks for all your help.

• Quick MySQLi security question

  - by Benjamin Falk

  I have a quick MySQLi security related question... For example, take a look at this code (gets in put from the user, checks it against the database to see if the username/password combination exist): $input['user'] = htmlentities($_POST['username'], ENT_QUOTES); $input['pass'] = htmlentities($_POST['password'], ENT_QUOTES); // query db if ($stmt = $mysqli->prepare("SELECT * FROM members WHERE username=? AND password = ?")) { $stmt->bind_param("ss", $input['user'], md5($input['pass'] . $config['salt'])); $stmt->execute(); $stmt->store_result(); // check if there is a match in the database for the user/password combination if ($stmt->num_rows > 0) {} } In this case, I am using htmlentities() on the form data, and using a MySQLi prepared statement. Do I still need to be using mysql_real_escape_string()?

• How can I turn a bunch of rows into aggregated columns WITHOUT using pivot in SQL Server 2005?

  - by cdeszaq

  Here is the scenario: I have a table that records the user_id, the module_id, and the date/time the module was viewed. eg. Table: Log ------------------------------ User_ID Module_ID Date ------------------------------ 1 red 2001-01-01 1 green 2001-01-02 1 blue 2001-01-03 2 green 2001-01-04 2 blue 2001-01-05 1 red 2001-01-06 1 blue 2001-01-07 3 blue 2001-01-08 3 green 2001-01-09 3 red 2001-01-10 3 green 2001-01-11 4 white 2001-01-12 I need to get a result set that has the user_id as the 1st column, and then a column for each module. The row data is then the user_id and the count of the number of times that user viewed each module. eg. --------------------------------- User_ID red green blue white --------------------------------- 1 2 1 2 0 2 0 1 1 0 3 1 2 1 0 4 0 0 0 1 I was initially thinking that I could do this with PIVOT, but no dice; the database is a converted SQL Server 2000 DB that is running in SQL Server 2005. I'm not able to change the compatibility level, so pivot is out. How can I accomplish this?

• Why would it be a bad idea to have database connection open between client requests?

  - by AspOnMyNet

  1) Book I’m reading argues that connections shouldn’t be opened between client requests, since they are a finite resource. I realize that max pool size can quickly be reached and thus any further attempts to open a connection will be queued until connection becomes available and for that reason it would be imperative that we release connection as soon as possible. But assuming all request will open connection to the same DB, then I’m not sure how having a connection open between two client requests would be any less efficient than having each request first acquiring a connection from connection pool and later returning that object to connection pool? 2) Book also recommends that when database code is encapsulated in a dedicated data access class, then method M opening a database connection should also close that connection. a) I assume one reason why M should also close it, is because if method M opening the connection doesn’t also close it, but instead this connection object is used inside several methods, then it’s more likely that a programmer will forget to close it. b) Are there any other reasons why a method opening the connection should also close it? thanx

• django setup with Apache, mod_wsgi and cx_Oracle

  - by pablo

  Hi, I need to setup the same django project on several identical servers. Details: - os - free edition of oracle enterprise linux 5 - Apache / mod_wsgi - python - custom python2.6 installation - oracle db with cx_Oracle What is the simplest way to set it up? Would you recommend creating a system user for the django project and use daemon mode? What type of user and what privileges does it need? Can I set ORACLE_HOME, LD_LIBRARY_PATH, PATH=$ORACLE_HOME/bin:$PATH for this user? Would you use a virtualenv for cx_Oracle? Can I somehow put the python2.6 inside the virtualenv so it will portable to other servers? Thanks

• set current user in asp.net mvc

  - by Tomh

  Hey guys, I'm not sure if this is the best way to do it, but I want to keep a user object alive during all requests of the current user. From reading several resources I learned that you should create your own IPrinciple which holds this. But I don't want to trigger the database every authentication request. Any recommendations on how to handle this? Is caching the db request a good idea? protected void Application_AuthenticateRequest(Object sender, EventArgs e) { HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie != null) { FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); User user; using (HgDataContext hg = new HgDataContext()) { if (Session["user"] != null) { user = (from u in hg.Users where u.EmailAddress == authTicket.Name select u).Single(); } else { user = Session["user"] as User; } } var principal = new HgPrincipal(user); Context.User = principal; } }

• How to define one-to-many connection between a same model through another model

  - by Mekajiki

  I want to define one-to-many relationship as follows; User has one introducer User has many newcomers(who is introduced by the user) Use "Introduction" model instead of adding a column to users table. My table and model definition is as follows; DB Scheme: create_table "introductions", force: true do |t| t.integer "introducer_id" t.integer "newcomer_id" t.datetime "created_at" t.datetime "updated_at" User model: class User < ActiveRecord::Base has_many :introductions, foreign_key: :introducer_id has_many :newcomers, through: :introductions, source: :newcomer belongs_to :introduction, foreign_key: :newcomer_id belongs_to :introducer end Introduction model: class Introduction < ActiveRecord::Base belongs_to :introducer, class_name: 'User' belongs_to :newcomer, class_name: 'User' end This works fine: user1.newcomers.push user2 but, user2.introducer # => nil How can I define belongs_to relationship correctly?

• sql server 2005 indexes and low cardinality

  - by Peanut

  How does SQL Server determine whether a table column has low cardinality? The reason I ask is because query optimizer would most probably not use an index on a gender column (values 'm' and 'f'). However how would it determine the cardinality of the gender column to come to that decision? On top of this, if in the unlikely event that I had a million entries in my table and only one entry in the gender column was 'm', would SQL server be able to determine this and use the index to retrieve that single row? Or would it just know there are only 2 distinct values in the column and not use the index? I appreciate the above discusses some poor db design, but I'm just trying to understand how query optimizer comes to its decisions. Many thanks.

• Spring Data MongoDB Date between two Dates

  - by sics

  i'm using Spring Data for MongoDB and got the following classes class A { List<B> b; } class B { Date startDate; Date endDate; } when i save an object of A it gets persisted like { "_id" : "DQDVDE000VFP8E39", "b" : [ { "startDate" : ISODate("2009-10-05T22:00:00Z"), "endDate" : ISODate("2009-10-29T23:00:00Z") }, { "startDate" : ISODate("2009-11-01T23:00:00Z"), "endDate" : ISODate("2009-12-30T23:00:00Z") } ] } Now i want to query the db for documents matching entries in b where a given date is between startDate and endDate. Query query = new Query(Criteria.where("a").elemMatch( Criteria.where("startDate").gte(date) .and("endDate").lte(date) ); Which results in the following mongo query: { "margins": { "$elemMatch": { "startDate" : { "$gte" : { "$date" : "2009-11-03T23:00:00.000Z"}}, "endDate" : { "$lte" : { "$date" : "2009-11-03T23:00:00.000Z"}} } } } but returns no resulting documents. Does anybody know what i'm doing wrong? I don't get it... Thank you very much in advance!!

• Can I get a dump of all my databases *except one* using mysqldump?

  - by Daniel Magliola

  I'm currently using mySQLdump to backup my dev machine and servers. There is one project I just started, however, that has a HUUUUUGE database that I don't really need backed up, and i'll be a big problem to add it to the rest of the backup cycle. I'm currently doing this: "c:\Program Files\mysql\MySQL Server 5.1\bin\mysqldump" -u root -pxxxxxx --all-databases g:\backups\MySQL\mysqlbackup.sql Is it possible to somehow specify "except this database(s)"? I wouldn't like to have to specify the list of DBs manually, since that would mean that I'd have to remember updating my backup batch file every time I create a new DB, and I know that's not gonna happen. EDIT: As you probably guessed from my command line above, i'm doing this on Windows, so I can't do any kind of fancy bash stuff, only wimpy .bat things. Alternatively, if you have other ideas to solve this same issue, they are more than welcome, of course! Thanks Daniel

• LINQ to SQL Web Application Best Practices

  - by derek

  In my experience building web applications, I've always used a n-tier approach. A DAL that gets data from the db and populates the objects, and BLL that gets objects from the DAL and performs any business logic required on them, and the website that gets it's display data from the BLL. I've recently started learning LINQ, and most of the examples show the queries occurring right from the Web Application code-behinds(it's possible that I've only seen overly simplified examples). In the n-tier architectures, this was always seen as a big no-no. I'm a bit unsure of how to architect a new Web Application. I've been using the Server Explorer and dbml designer in VS2008 to create the dbml and object relationships. It seems a little unclear to me if the dbml would be considered the DAL layer, if the website should call methods within a BLL, which then would do the LINQ queries, etc. What are some general architecture best practices, or approaches to creating a Web Application solution using LINQ to SQL?

• Best way to encrypt certain fiels in SQL Server 2008?

  - by Josh

  I'm writing a .net web app that will read and write information to a SQL 2008 backend database. Some of this information will be highly confidential in nature so I want to encrypt certain data elements. I dont want to use TDE or any full-database encryption for performance reasons. My main concern is protecting this sensitive data as a last resort against a SQL injection or even a database server compromise. My question is what is the best way to do this to preserve performance? Is it faster to use the SQL2008 encryption functions such as EncryptByKey, or would it be faster to encrypt and decrypt the data in the .NET web app itself using a symmetric key stored in the secure web.config and store the encrypted values in the DB?

• How can I concatinate a subquery result field into the parent query?

  - by Pure.Krome

  Hi folks, DB: Sql Server 2008. I have a really (fake) groovy query like this:- SELECT CarId, NumberPlate (SELECT Owner FROM Owners b WHERE b.CarId = a.CarId) AS Owners FROM Cars a ORDER BY NumberPlate And this is what I'm trying to get... => 1 ABC123 John, Jill, Jane => 2 XYZ123 Fred => 3 SOHOT Jon Skeet, ScottGu So, i tried using AS [Text()] ... FOR XML PATH('') but that was inlcuding weird encoded characters (eg. carriage return). ... so i'm not 100% happy with that. I also tried to see if there's a COALESCE solution, but all my attempts failed. So - any suggestions?

• EF problem with entity re-ordering and uniqueness constraint

  - by wpfwannabe

  I am using Entity Framework and I've come to an interesting stumbling block. Let's say there is a db table "Item" with "sequence" column of type int (and others of course). Column "sequence" must be unique and it is used for (re)ordering of items. EF maps this table to "Item" class with "sequence" int property. Now let's say I want to swap position of two items by mutually exchanging each other's sequence number. Upon calling SaveChanges() EF throws an exception complaining about "sequence" uniqueness. It probably generates two UPDATEs and the first one probably fails. I assume that plain SQL solution to this issue is using a third UPDATE to introduce a unique sequence value in the process but I am stuck with EF. Any thoughts?

• JPA, scope, and autosave?

  - by arinte

  I am using JPA and lets say I do something like this public class MoRun extends Thread {... public void run() { final EntityManagerFactory emFactory = Persistence.createEntityManagerFactory("pu"); EntityManager manager = emFactory.createEntityManager(); manager.setFlushMode(FlushModeType.COMMIT); someMethod(manager); ... } public void someMethod(EntityManager manager){ Query query = manager.createNamedQuery("byStates"); List<State> list = query.getResultList(); for (State state : list) { if(someTest) state.setValue(...) } ... } So for those objects that pass "someTest" and values are updated are those changes automatically persisted to the db even though there is no transaction and I don't explicitly "manager.save(state)" the object? I ask because it seems like it is and I was wondering if the flush is doing it?

• ASP.NET application partially reading external configuration

  - by Trent

  I have an ASP.NET web app and am attempting to reference an external config (using enterprise application blocks configuration) for some of the configuration but it is not entirely working. I previously had all of the configuration info in the web.config (and it was working), but we are wanting to share some of this configuration information between multiple apps. When I put configurationSource tag in the web.config, and read the configuration through the WebConfigurationManager object, it loads some of the external config info (Logging) but not the connectionStrings and not the custom section I created. So its reading it (logging is working), but some dots aren't being connected and my connection strings aren't coming through. Again, it worked when it was all in the web.config. Any idea what needs to change to be able to reference an external configuration source and have it all come through?

• SQL Server: export data via SQL query?

  - by rlb.usa

  I have FK and PK all over my db and table data needs to be specified in a certain order or else I get FK/PK insertion errors. I'm tired of executing the wizard again and again to transfer data one table at a time. In the SQL Server export data wizard there is an option to "Write a query to specify the data to transfer". I'd like to write the query myself and specify the correct order. Will this solve my problem? How do I do this? Can you provide a sample query (or link to one) The databases are on two different servers - SQL Server 2008 on each ; The database names & permissions are the same ; each table name & col is the same ; I need Identity Insert for each table.

• Js/Jquery bind Datatable or Datalist

  - by Robin Rieger

  Scenario I have a input box for post codes. When you put in a postcode it makes a call to a web service and gets all the suburb names back and binds them to a list, like an input dropdown list. This works when I return a List<string> from the web service for just the names. No problem. The problem arises when I go to save the values to the db. When it gets saved I cannot save the name of the suburb in the suburb column in the db. I have to save the id of that suburb for the foreign key constraint. So then I changed the List<> thing slighty and cheated and returned the following. <ArrayOfString> <string>8213</string> <string>BROOKFIELD</string> <string>8214</string> <string>CHAPEL HILL</string> <string>8215</string> <string>FIG TREE POCKET</string> etc.... The reason for this is so I can have the value of the item in the drop down as the id and hence can save that in the code behind on save. To do this, I did the following: $(result).each(function (index, value) { var suburbname; var pattern = new RegExp('[0-9*]'); var m = pattern.exec(value); if (m == null) { suburbname = value var o = new Option(suburbname, suburbid); /// jquerify the DOM object 'o' so we can use the html method $(o).html(suburbname); $(document.getElementById('<%= suburb.ClientID %>')).append($("<option></option>") .attr("value", suburbid) .text(suburbname)); } else { suburbid = value } That works as well... the drop down only has name and the value for those is the number The problem....? I am making assumptions above which I don't like... I.e. that the name never has a number it, that the web service will always return the id first to set the id before running the add to the dropdown for the first time. It just feels wrong.... :S (thoughts?) So, if I change the web service to return a datatable, to out the following (which is what the whole query returns): <Suburbs diffgr:id="Suburbs1" msdata:rowOrder="0"> <SuburbID>8213</SuburbID> <SuburbName>BROOKFIELD</SuburbName> <StateID>4</StateID> <StateCode>07</StateCode> <CountryCode>61</CountryCode> <TimeZones>10.00</TimeZones> <Postcode>4069</Postcode> </Suburbs> Is there a way of acheiving the same as above in js/jquery. So when the user inputs the postcode the webservice returns the datatable and then binds it to the select with the SuburbID going into the value and the name going into the text??? Any other ways I could return the data from the web service to solve this? Note: essentially I need the option to look like this: <option value="8213">BROOKFIELD</option> I also thought I could make a second call to get just the id on the bind of the text... but I kind of want to only make one call.... Thanks in adance, Cheers Robin .net, C#, js, jquery, web service..... Solution with guidance from Billy The adding to the select using the other method below did not work, but my original way did once I had the correct variables so just used that.... The service returns: <ArrayOfMyClass> <MyClass> <ID>8213</ID> <Name>BROOKFIELD</Name> </MyClass> ... etc The js is: (note: it is onchange of the postcode input box. it runs a web service and then on success runs the following) function OnCompleted(result) { var _suburbs = result; var i = 0; $(_suburbs).each(function () { var SuburbName = _suburbs[i].Name; var SuburbID = _suburbs[i].ID; $(document.getElementById('<%= suburb.ClientID %>')).append($("<option></option>") .attr("value", SuburbID) .text(SuburbName)); i = i + 1; });

• How can I pass a raw System.Drawing.Image to an .ashx?

  - by Mike C

  I am developing an application that stores images as Base64 strings in xml files. I also want to allow the user to crop the image before saving it to the file, preferably all in memory without having to save a temp file, and then delete it afterwards. In order to display the newly uploaded image, I need to create a HTTP handler that I can bind the asp:Image to. The only examples for doing this online require passing the .ashx an ID and then pulling the image from a DB or other data store. Is it possible to somehow pass the raw data to the .ashx in order to get back the image? Thanks, Mike

• How do views reduce code duplication?

  - by Debuger

  Hi! I read something like this about db views: Views are incredibly powerful and useful for one reason that stands out above all the other very good reasons. They reduce code duplication. That is, in most cases, the bottom line. If a query will be used in three or more places, then a view will drastically simplify your changes if the schema or query parameters change. I once had to edit 22 stored procedures to change some query logic. If the original architecture had utilized views, then I would have had only three changes. Can anyone explain to me how it works, and maybe give me some examples? Best regards!

• Querying a Single Column with LINQ

  - by Hossein Margani

  Hi Every one! I want to fetch array of values of a single column in a table, for example, I have a table named Customer(ID,Name), and want to fetch ids of all customers. my query in LINQ is: var ids = db.Customers.Select(c=>c.ID).ToList(); The answer of this query is correct, but I ran SQL Server Profiler, and saw the query which was like this: SELECT [t0].[ID], [t0].[Name] FROM [dbo].[Customer] AS [t0] I understood that LINQ selects all columns and then creates the integer array of ID fields. How can I write a LINQ query which generates this query in SQL Server: SELECT [t0].[ID] FROM [dbo].[Customer] AS [t0] Thank you.

• Compact Framework : Read a SQL CE database on a PDA from a PC

  - by CF_Maintainer

  Hello, I have tasked with upgrading a CF Framework 1.1 suite of apps. Currently, the PC starts a server [after confirming via RAPI that the device exists and is connected] and spawns a app on the PDA as the client. The client process on the PDA talks with the db on the PDA and returns records to the PC app [using SQL CE 2.0. OpenNETCF 1.4 for communication/io]. I have a chance to upgrade the PC and PDA suite of apps to Framework 3.5 & CF 3.5 respectively. Due to a business requirement, I cannot get rid of workflow requiring the PC app to show a preview of the work done on the PDA. Question : Are there better ways to achieve the above in general with the constraints I have? I would really appreciate any Ideas/advice.
