  • How can I have a Visual Studio Report(.rdlc) with account information and also a chart in the same r

    - by Paul Mendoza
    I'm working on a report in Visual Studio 2008 with their Report tooling and I'm not sure how to approach this conceptually. I have a report I want to generate. At the top of the report will be a bunch of information about a customer of our site (Name, Address, Phone). Then below will be a chart of the purchases that customer has each month. My problem is that I want the content at the top of the page to use a query that selects from my Users table in my database. But then I need another query that gets all of the purchases grouped by month. I've thought one way to approach this would be to place a subreport on the parent report that only contained the chart. The parent report would have the details of the account. Is this the correct approach?

  • Select a row having a column with max value - On a date range

    - by Abhi
    Excuse me for posting a similar question. Please consider this: date value 18/5/2010, 1 pm 40 18/5/2010, 2 pm 20 18/5/2010, 3 pm 60 18/5/2010, 4 pm 30 18/5/2010, 5 pm 60 18/5/2010, 6 pm 25 19/5/2010, 6 pm 300 19/5/2010, 6 pm 450 19/5/2010, 6 pm 375 20/5/2010, 6 pm 250 20/5/2010, 6 pm 310 The query is to get the date and value for each day such that the value obtained for that day is max. If the max value is repeated on that day, the lowest time stamp is selected. The result should be like: 18/5/2010, 3 pm 60 19/5/2010, 6 pm 450 20/5/2010, 6 pm 310 The query should take in a date range like the one given below and find results for that range in the above fashion: where date = to_date('26/03/2010','DD/MM/YYYY') AND date < to_date('27/03/2010','DD/MM/YYYY')

  • Google App Engine PersistenceManager can process multiple objects ?

    - by Frank
    I have some code like this : PersistenceManager pm=PMF.get().getPersistenceManager(); String query="select from "+PayPal_Message.class.getName()+" where processed == false order by time desc"; List<PayPal_Message> messages=(List<PayPal_Message>)pm.newQuery(query).execute(); if (messages.isEmpty()) { } else { for (PayPal_Message g : messages) { Contact_Info_Entry A_Contact_Entry=Process_PayPal_Message_To_Get_A_License(g.getContent().getValue()); pm=PMF.get().getPersistenceManager(); try { pm.makePersistent(A_Contact_Entry); g.setProcessed(true); pm.makePersistent(g); } catch (Exception e) { Send_Email(Email_From,"[email protected]","Servlet Error Message [ "+time+" ]",new Text(e.toString())); } // finally { pm.close(); } } } pm.close(); I wonder if it's ok to use the pm above to process multiple objects before closing it. Or do I have to get and close pm for processing each object ?

  • How sql server evaluates the multiple different joins?

    - by ziang
    Hi, i have a general question about how sql server evaluates the joins.The query is SELECT * FROM TableA INNER JOIN TableB ON TableB.id = TableA.id LEFT JOIN TABLEC ON TABLEC.id = TABLEB.id Q1: What tables is the left join based on? I know it will based on the TABLEC but what is the other one? Is it the result of the first inner join or the TABLEB specified in the left join condition? Q2: Is "LEFT JOIN TABLEC ON TABLEC.id = TABLEB.id" equivalent to "LEFT JOIN TABLEC ON TABLEB.id = TABLEC.id" Q3: Is the query equivalent to the following one? (with TABLEB.id replaced by TABLEA.id?) SELECT * FROM TableA INNER JOIN TableB ON TableB.id = TableA.id LEFT JOIN TABLEC ON TABLEC.id = TABLEA.id Thank you!

  • My Lucene queries only ever find one hit

    - by Bob
    I'm getting started with Lucene.Net (stuck on version 2.3.1). I add sample documents with this: Dim indexWriter = New IndexWriter(indexDir, New Standard.StandardAnalyzer(), True) Dim doc = Document() doc.Add(New Field("Title", "foo", Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) doc.Add(New Field("Date", DateTime.UtcNow.ToString, Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.NO)) indexWriter.AddDocument(doc) indexWriter.Close() I search for documents matching "foo" with this: Dim searcher = New IndexSearcher(indexDir) Dim parser = New QueryParser("Title", New StandardAnalyzer()) Dim Query = parser.Parse("foo") Dim hits = searcher.Search(Query) Console.WriteLine("Number of hits = " + hits.Length.ToString) No matter how many times I run this, I only ever get one result. Any ideas?

  • Apache basic auth, mod_authn_dbd and password salt

    - by Cristian Vrabie
    Using Apache mod_auth_basic and mod_authn_dbd you can authenticate a user by looking up that user's password in the database. I see that working if the password is held in clear, but what if we use a random string as a salt (also stored in the database) then store the hash of the concatenation? mod_authn_dbd requires you to specify a query to select that password not to decide if the user is authenticated of not. So you cannot use that query to concatenate the user provided password with the salt then compare with the stored hash. AuthDBDUserRealmQuery "SELECT password FROM authn WHERE user = %s AND realm = %s" Is there a way to make this work?

  • Meaning of tA tC and tP

    - by Greg Wiley
    If this is a duplicate I appoligize, but looking for two-letter strings is quite hard in any search. I'm looking for the meaning of tA tC and tP in the context of a mysql query. And in the spirit of "teaching a man how to fish" it would be great if you could point me in the right direction of where to find this info in the future. Edit: The Query $wpdb->get_row($wpdb->prepare("SELECT tA.* FROM ".AMYLITE_ADS." tA, ".AMYLITE_ADS_CAMPAIGNS." tC, ".AMYLITE_PACKAGES." tP WHERE tA.id=tC.ad_id AND tC.campaign_id=tP.campaign_id AND tP.zone_id=%d AND tP.date_end>CURDATE() GROUP BY tA.id ORDER BY RAND()", $zone->id));

  • Left Join not returning all rows

    - by DisgruntledGoat
    I have this query in MySQL: SELECT pr.*, pr7.value AS `room_price_high` FROM `jos_hp_properties` pr LEFT OUTER JOIN `jos_hp_properties2` pr7 ON pr7.property=pr.id WHERE pr7.field=23 The jos_hp_properties table has 27 rows but the query only returns one. Based on this question I think it may be because of the WHERE clause. The jos_hp_properties2 table has fields id, property, field, value, where field is a foreign key to a third table (which I don't need to get data from). Is there a way to select all the rows from the first table, including the value from table #2 where the field is 23 (or NULL if there is no field 23)?

  • Stored proc executes >30 secs when called from website, but <1 sec when called from ssms

    - by Blootac
    I have a stored procedure that is called by a website to display data. Today the web page has started timing out so I got profiler going and saw the query that was taking too long. I then ran the same query in management studio, under the same user login, and it takes less than a second to return. Is there anything obvious that could be causing this? I can't think of a reason why when ASP calls the stored proc it takes 30 secs but when I call it it's fine. Thanks

  • How to dynamically order many-to-many relationship in JPA or HQl?

    - by Indrek
    I have a mapping like this: @ManyToMany(cascade = CascadeType.PERSIST) @JoinTable( name="product_product_catalog", joinColumns={@JoinColumn(name="product_catalog", referencedColumnName="product_catalog")}, inverseJoinColumns={@JoinColumn(name="product", referencedColumnName="product")}) public List<Product> products = new ArrayList<Product>(); I can fetch the products for the catalog nicely, but I can't (dynamically) order the products. How could I order them? I probably have to write a many-to-many HQL query with the order-by clause? I though of passing the orderBy field name string to the query, or is there a better solution? Tables are: products, product_catalog, product_product_catalog (associative table) P.S. Using Play! Framework JPASupport for my entities.

  • Writing a post search algorithm.

    - by MdaG
    I'm trying to write a free text search algorithm for finding specific posts on a wall (similar kind of wall as Facebook uses). A user is suppose to be able to write some words in a search field and get hits on posts that contain the words; with the best match on top and then other posts in decreasing order according to match score. I'm using the edit distance (Levenshtein) "e(x, y) = e" to calculate the score for each post when compared to the query word "x" and post word "y" according to: score(x, y) = 2^(2 - e)(1 - min(e, |x|) / |x|) Each word in a post contributes to the total score for that specific post. This approach seems to work well when the posts are of roughly the same size, but sometime certain large posts manages to rack up score solely on having a lot of words in them while in practice not being relevant to the query. Am I approaching this problem in the wrong way or is there some way to normalize the score that I haven't thought of?

  • Generic documentation guide-lines for implementation details

    - by mgj
    Hi..:) For documentation and presentation purposes, we often find professionals/students creating SRS, coding guidelines etc. for these things there is some kind of a checklist which one could use to appropriately match what could relate to a specific case and accordingly one does a documentation for each. On those grounds could you please give me some sort of a checklist( any points/guidelines) one could use for going about Implementation( in the form of Implementation Details) in Python and C++ . Although this might sound specific as the query is "Implementation Details" and is different for different cases as one goes about the REAL implementation, I just want a SET of guidelines one should follow ( Preferably In Python, C++ specific, even for any other language is Welcome) if this( Implementation Details ) has to also be documented or presented. Hope the question is clear, I am sorry if it still sounds ambiguous, I guess this is the best I could do to frame my query. Thank you for your time...:)

  • MySQL break out group clause from subquery

    - by Anton Gildebrand
    Here is my query SELECT COALESCE(js.name,'Lead saknas'), count(j.id) FROM jobs j LEFT JOIN job_sources js ON j.job_source=js.id LEFT JOIN (SELECT * FROM quotes GROUP BY job_id) q ON j.id=q.job_id GROUP BY j.job_source The problem is that it's allowed for each job to have more than one quote. Because of that i group the quotes by job_id. Now sure, this works. But i don't like the solution with a subquery. How can i break out the group clause from the subquery to the main query? I have tried to add q.job_id to the main group clause, both before and after the existing one but don't get the same results.

  • GQL, Aggregation and Order By

    - by Koran
    Hi, How can GQL support ORDER BY when it does not support aggregation? The question is - if say the result of the query is more than 1000, does ORDER BY return fully ordered list or only the first 1000 items which is then ordered? To explain the question more: is conceptually MIN() same as query.orderby('asc').fetch(1)? If it is properly ordering the list, then how can it not provide COUNT(), since to properly order the list, GQL possibly has to parse through the whole list - in which case, COUNT() is not an issue at all? Or is item indexed and kept in some type of tree so that it does not need to parse it all the time?
