  • How to deal with large result sets with Linq to Entities?

    - by user169867
    I have a fairly complex linq to entities query that I display on a website. It uses paging so I never pull down more than 50 records at a time for display. But I also want to give the user the option to export the full results to Excel or some other file format. My concern is that there could potentially be a large # of records all being loaded into memory at one time to do this. Is there a way to process a linq result set 1 record at a time like you could w/ a datareader so only 1 record is really being kept in memory at a time? I'd appreciate any help. Thanks

  • oracle sql developer is truncating my results

    - by nont
    I'm calling a stored function like this: select XML_INVOICE.GENERATE_XML_DOC('84200006823') from dual; The query results then show up in a table underneath, which I can right click and select "Export Date" - XML <?xml version='1.0' encoding='UTF8' ?> <RESULTS> <ROW> <COLUMN NAME="XML_INVOICE.GENERATE_XML_DOC('84200006823')" <![CDATA[<xml>yada yada</xml><morexml>...]]></COLUMN> </ROW> </RESULTS> The problem is the "..." - SQL Developer (2.1.0.63 on Linux) is not showing all the data - its truncating the result and appending the ellipsis. This is of no use to me. How do I get it to export ALL of my data?

  • Select rows in random order and then reverse it

    - by Faruz
    I need to select rows in random order and return a query which holds the rows in both regular order and in reverse order. This is done to simulate a fantasy draft for a basketball game I'm working on. For example, I need a result set as followed: team1 1 team2 2 team6 3 team9 4 team9 5 team6 6 team2 7 team1 8 As you can see, the first four teams are random then then following four are in reverse order. Hope I managed to explain the problem, if not - please comment and I'll explain further.

  • Linq to NHibernate - How to return a parent object with only certain child objects included

    - by vakman
    Given a simplified model like the following: public class Enquiry { public virtual DateTime Created { get; set; } public virtual Sender Sender { get; set; } } public class Sender { public virtual IList<Enquiry> Enquiries { get; set; } } How can you construct a Linq to Nhibernate query such that it gives you back a list of senders and their enquiries where the enquiries meet some criteria. I have tried something like this: return session.Linq<Enquiry>() .Where(enquiry => enquiry.Created < DateTime.Now) .Select(enquiry => enquiry.Sender) In this case I get an InvalidCastException saying you can't cast type Sender to type Enquiry. Any pointers on how I can do this without using HQL?

  • SQL Server - Percent based Full Text Search

    - by Sukhminder Singh
    Hi I want to conduct search on a particular column of a table in such a way that returning result set should satify following 2 conditions: Returning result set should have records whose 90% of the characters matches with the given search text. Returning result set should have records whose 70% of the consecutive characters matches with the given search text. It implies that when 10 character word Sukhminder is searched, then: it should return records like Sukhmindes, ukhminder, Sukhmindzr, because it fulfils both of the above mentioned conditions. But it should not return records like Sukhmixder because it does not fulfil the second condition. Likewise, It should not return record Sukhminzzz because it does not fulfil the first condition. I am trying to use Full Text Search feature of SQL Server. But, could not formulate the required query yet. Kindly reply ASAP.

  • Does AsEnumerable() cache all result (LINQ)

    - by Akshay
    When we call a query operator on a sequence, a sequence-specific operator gets called. I mean if i call Where<>() operator on IEnumerable<>, the operator that will be called will be defined in Enumerable class and if it's called on IQueryable<>, the one defined in Queryable class will be called. Consider the operator Reverse, defined in the Enumerable class. If i want to call it on Iqueryable<> then I must use the AsEnumerable<>() operator to first convert it into IEnumerable<>. db.Countries.OrderBy(cntry=>cntry.CountryName).AsEnumerable().Reverse() But the Reverse operator got to have all records at the same time so that it can reverse them. In the above code do all the records get loaded in memory first and then the Reverse() operator is reversing it ?

  • SQL LIKE question

    - by user176121
    I was wondering if there's a drawback (other than bad practice) to using something like this SELECT * FROM my_table WHERE id LIKE '1'; where id is an integer. I know you're supposed to use id=1 but I am writing a java program and if everything can use LIKE it'll be a lot easier for me. Also, so far, everything works fine; I get the correct query results, so if there is no drawback I will continue doing it like this. edit: I am using MySQL.

  • mysql join with a "bounce" off a third table

    - by Enkay
    I have 3 mysql tables. companies with company_id and company_name products with product_id and company_id names with product_id, product_name and other info about the product I'm trying to output the product_name and the company_name in one query for a given product_id. Basically I need information from the names and companies tables and the link between them is the products table. How do I do a join that needs to "bounce" off a third table? Something like this but this obviously doesn't work : SELECT product_name, company_name FROM names LEFT OUTER JOIN companies ON (names.product_id = products.product_id and products.company_id = companies.company_id) WHERE product_id = '12345' Thanks!

  • Returning more than 1000 rows in classic asp adodb.recordset

    - by peg_leg
    My code in asp classic, doing a mssql database query: rs.pagesize = 1000 ' this should enable paging rs.maxrecords = 0 ' 0 = unlimited maxrecords response.write "hello world 1<br>" rs.open strSql, conn response.write "hello world 2<br>" My output when there are fewer than 1000 rows returned is good. More than 1000 rows and I don't get the "hello world 2". I thought that setting pagesize sets up paging and thus allows all rows to be returned regardless of how many rows there are. Without setting pagesize, paging is not enable and the limit is 1000 rows. However my page is acting as if pagesize is not working at all. Please advise.

  • How can I figure out a users postal code if I have their latitude / longitude location? Need help w

    - by mike
    I'm using HTML5 geolocation to collect the users lat / long and I need to figure out what their postal code is as well. I have a database of all the lat / long for each postal code in the US & Canada. How can I write a query to find out what their postal code is? Below, is an example of how the data is structured in the 'zips' table. Country PostalCode Latitude Longitude USA 0051 40.813078 -73.046388 USA 00616 18.426456 -66.673779 I can't do a 'SELECT PostalCode FROM zips WHERE Latitude = user.lat AND Longitude = user.long'. I believe I need to find the nearest lat / long. Any suggestions on how I can write this?

  • Notify a content resolver when normal sql insert or update

    - by user1400538
    I have created a small content provider (which I only use to query a db table and fetch some value). I have confirmed that the provider works fine. The table values get updated on a regular basis through normal sql insertions(and not through anycontent provider) Whenever an insert/update or delete occurs through a normal sqlite operation as mentioned above, I need to notify the content resolvers which was written to communicate with the content provider just for quering database and fetch some values. Is this, possible? If yes what need to be done? Any help is appreciated.

  • Silverlight - Timeout Issue

    - by user70192
    Hello, I have a Silverlight 3 application that is querying a large dataset. This query is taking over one minute. After approx. one minute into the attempt, an error is getting logged into the event viewer that says: "Membership credential verification failed" Oddly queries that are taking shorter than 1 minute are running successfully. Because of this, I do not believe it is a "credential" issue, unless somehow it is expiring. But how do I set the expiration? I have no idea what else this could be. Thank you,

  • How can I avoid setting some columns if others haven't changed, when working with Linq To SQL?

    - by Patrick Szalapski
    In LINQ to SQL, I want to avoid setting some columns if others haven't changed? Say I have dim row = (From c in dataContext.Customers Where c.Id = 1234 Select c).Single() row.Name = "Example" ' line 3 dataContext.SubmitChanges() ' line 4 Great, so LINQ to SQL fetches a row, sets the name to "Example" in memory, and generates an update SQL query only when necessary--that is, no SQL will be generated if the customer's name was already "Example". So suppose on line 3, I want to detect if row has changed, and if so, set row.UpdateDate = DateTime.Now. If row has not changed, I don't want to set row.UpdateDate so that no SQL is generated. Is there any good way to do this?

  • Jquery counting elements by class what is the best way to implement this?

    - by 133794m3r
    Ok what i'm trying to do is to count all of the elements in the current page with the same class and then i'm going to use it to be added onto a name for a input form. Basically i'm allowing users to click on an and then by doing so add another one for more of the same type of items. But i can't think of a way to count all of these simply with jquery/javascript. I was going to then name the item as something like name="whatever(total+1)", if anyone has a simple way to do this i'd be extremely grateful as javascript isn't exactly my native tongue and stack overflow usually has a ton of great answers and a great community so i'm hoping my query will not go unheard.

  • Know if a Visual Studio Website project is recompiling itself in the background?

    - by jdk
    A number of team members update a central ASP.NET dev site (Website project, not a Web application type). Some kinds of changes cause a recompile/rebuild in it. The large website takes a while to recompile and we've noticed it will still seemingly serve out dynamic pages before everything is internally updated. During the site's "gestation" period, our mileage varies while hitting it. Sometimes we get a correct page, sometimes an compilation error page that will eventually be served up without a compilation error, and at other times an unexpected hybrid. Is it possible to query an ASP.NET website application to see if it's currently compiling or rebuilding itself? If so I would write a status page that the team could reference when they're getting weird behaviour, so they would know to wait. Update: Our team often edit files manually on the dev server. For production we'd make pre-compiled pushes. The dev environment is a little more malleable and ever-changing so I'm looking for a solution to reducing the "confusion" there.

  • WCF methods sharing a dictionary

    - by YeomansLeo
    I'm creating a WCF Service Library and I have a question regarding thread-safety consuming a method inside this library, here is the full implementation that I have until now. namespace WCFConfiguration { [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Single)] public class ConfigurationService : IConfigurationService { ConcurrentDictionary<Tuple<string,string>, string> configurationDictionary = new ConcurrentDictionary<Tuple<string,string>, string>(); public void Configuration(IEnumerable<Configuration> configurationSet) { Tuple<string, string> lookupStrings; foreach (var config in configurationSet) { lookupStrings = new Tuple<string, string>(config.BoxType, config.Size); configurationDictionary.TryAdd(lookupStrings, config.RowNumber); } } public void ScanReceived(string boxType, string size, string packerId = null) { } } } Imagine that I have a 10 values in my configurationDictionary and many people want to query this dictionary consuming ScanReceived method, are those 10 values be shared for each of the clients that request ScanReceived? Do I need to change my ServiceBehavior? The Configuration method is only consumed by one person by the way.

  • has anyone tried designing a webpage for psp?

    - by lock
    erm im trying to make a personal bible for my psp (i tried googling but the only bible version i've seen on my skimming is on KJV and im trying to make mine have 3 versions namely TNIV, NLT and Amplified Bible) so my only solution was to make on for myself and my approach was to save an html file on my mem-stick and open it up through the console's browser my concerns are: 1. how does the psp browser handle css and javascript? 2. is there a doctype declaration specifically designed for the psp browser? 3. can i use any local database to store my texts for easier query or do i have no choice but rely on static text files? 4. is there anyone in SO who have experienced developing a page for this console and can he/she give me some tips and advice? thanks much in advance for your responses.. :)

  • Finding parents where child collection does not contain an item

    - by Colin Bowern
    I am trying to get a list of parents where the child collection does not contain an item of a specific type. The LINQ equivalent would be something like: dataset.Where(x => x.Items.FirstOrDefault(y => y.Type.Code == "ABC") == null) The object model is Parent Child (Items) Type Code If Parent is my aggregate root, how would I model this in NHibernate criteria/query? Here's my first attempt: var results = session.CreateCriteria<Parent>() .CreateCriteria("Items") .CreateCriteria("Type") .Add(Restrictions.Not(Restrictions.Eq("Code", "ABC"))) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Parent>(); This doesn't seem to return the right entities - it just returns them all.

  • Spring+JSP url building best practices

    - by dotsid
    I wonder if there are any good practices for addressing Spring controllers in JSP. Suppose I have controller: @Controller class FooController { // Don't bother about semantic of this query right now @RequestMapping("/search/{applicationId}") public String handleSearch(@PathVariable String applicationId) { [...] } } Of course in JSP I can write: <c:url value="/search/${application.id}" /> But it's very hard to change url then. If you familiar with Rails/Grails then you now how this problem resolved: redirect_to(:controller => 'foo', :action = 'search') But in Spring there is so much UrlMappers. Each UrlMapper have own semantic and binding scheme. Rails alike scheme simply doesn't work (unless you implement it yourself). And my question is: are there any more convenient ways to address controller from JSP in Spring?

  • How to do rolling balances in Linq2SQL

    - by David Liddle
    Given an account with a list of transactions I would like to output a query that shows each transaction with the rolling balance (just like you would see on an online banking account). TRANSACTIONS - ID - DATE - AMOUNT Here is what I created in T-SQL however was wondering if this can be translated to linq2sql code? select T.ID, convert(char(10), T.DATE, 101) as 'DATE', T.AMOUNT, (select sum(O.AMOUNT) from TRANSACTIONS O where O.DATE < T.DATE or (O.DATE = T.DATE and O.ID <= T.ID)) 'BALANCE' from TRANSACTIONS as T where T.DATE between @pStartDate and @pEndDate order by T.DATE, T.ID Alternatively I guess my other option is to just call a stored procedure for these kind of results. However, I have Services which call Repositories and didn't really want to put the sproc call in the Repository.

  • Internet Explore works very slowly executing JS code

    - by Sergey Basharov
    There is a page that uses PHP to fetch search results from Google Search API and then it puts the results on the page some funny way in a circle. Code and may look crappy but seems that it works more or less fine in Firefox. When you enter a search query and click submit button or Next/Previous links, it fills the wheel with results. The problem is its work in IE. It works there very slowly and then it doesn't clear the wheel before filling in new data, but puts it over that. My friend asked me to help him with this code. Please give me a piece of advice how I can fix it. Thanks so much!

  • How do I do a semijoin using SQLAlchemy?

    - by Jason Baker
    http://en.wikipedia.org/wiki/Relational_algebra#Semijoin Let's say that I have two tables: A and B. I want to make a query that would work similarly to the following SQL statement using the SQLAlchemy orm: SELECT A.* FROM A, B WHERE A.id = B.id AND B.type = 'some type'; The thing is that I'm trying to separate out A and B's logic into different places. So I'd like to make two queries that I can define in separate places: one where A uses B as a subquery, but only returns rows from A. I'm sure this is fairly easy to do, but an example would be nice if someone could show me.
