  • Avoid writing SQL queries altogether in SSIS

    - by Jonn
    Working on a Data Warehouse project, the guy that gave us the tutorial advised that we stick to using SQL queries over defining a lot of data flow transformations, citing points like it'll consume a lot of memory on the ETL box so we'd rather leave the processing to the DB box. Is this really advisable? Where's the balance between relying on GUI tools over executing a bunch of SQL scripts on your Integration package? And honestly, I'd like to avoid writing SQL queries as much as I can.

  • What is the recommended approach towards multi-tenant databases in MongoDB?

    - by Braintapper
    I'm thinking of creating a multi-tenant app using MongoDB. I don't have any guesses in terms of how many tenants I'd have yet, but I would like to be able to scale into the thousands. I can think of three strategies: All tenants in the same collection, using tenant-specific fields for security 1 Collection per tenant in a single shared DB 1 Database per tenant The voice in my head is suggesting that I go with option 2. Thoughts and implications, anyone?

  • Adding metadata attributes to MySQL table

    - by Jack
    I would like to add custom attributes to a MySQL table which I can read via php. These attributes are not to interfere with the table itself - they are primarily accessed by php code during code generation time and these attributes HAVE to reside in the DB itself. Something similar in concept to .NET reflection. Does MySQL support anything like this? Thanks.

  • Query column and everything subordinate (hard to describe, non native speaker, PLS let me explain)

    - by MAD9
    A few weeks ago, I asked a question about how to generate hierarchical XML from a table, that has a parentID column. It all works fine. The point is, according to the hierarchy, I also want to query a table. I'll give you an example: Thats the table with the codes: ID CODE NAME PARENTID 1 ROOT IndustryCode NULL 2 IND Industry 1 3 CON Consulting 1 4 FIN Finance 1 5 PHARM Pharmaceuticals 2 6 AUTO Automotive 2 7 STRAT Strategy 3 8 IMPL Implementation 3 9 CFIN Corporate Finance 4 10 CMRKT Capital Markets 9 From which I generate (for displaying in a TreeViewControl) this XML: <record key="1" parentkey="" Code="ROOT" Name="IndustryCode"> <record key="2" parentkey="1" Code="IND" Name="Industry"> <record key="5" parentkey="2" Code="PHARM" Name="Pharmaceuticals" /> <record key="6" parentkey="2" Code="AUTO" Name="Automotive" /> </record> <record key="3" parentkey="1" Code="CON" Name="Consulting"> <record key="7" parentkey="3" Code="STRAT" Name="Strategy" /> <record key="8" parentkey="3" Code="IMPL" Name="Implementation" /> </record> <record key="4" parentkey="1" Code="FIN" Name="Finance"> <record key="9" parentkey="4" Code="CFIN" Name="Corporate Finance"> <record key="10" parentkey="9" Code="CMRKT" Name="Capital Markets" /> </record> </record> </record> As you can see, some codes are subordinate to others, for example AUTO << IND << ROOT What I want (and have absolutely no idea how to realise or even, where to start) is to be able to query another table (where one column is this certain code of course) for a code and get all records with the specific code and all subordinate codes For example: I query the other table for "IndustryCode = IND[ustry]" and get (of course) the records containing "IND", but also AUTO[motive] and PHARM[aceutical] (= all subordinates) Its an SQL Express Server 2008 with Advanced Services.

  • ASP.NET- forcing child/container events to fire before parent onload?

    - by Hans Gruber
    I'm working on a questionnaire type application in which questions are stored in a database. Therefore, I create my controls dynamically on every Page.OnLoad. This works like a charm and ViewState is persisted between postbacks because I ensure that my dynamic controls always have the same generated Control.ID. In addition to the user control that dynamically populates the questions, my questionnaire page also contains a 'Status' section (also encapsulated by a user control) which represents the status of the questionnaire (choices are 'Complete', 'Started' or 'In Progress'). If the user changes the status of questionnaire (i.e. from 'In Progress' to 'Complete'), I need to postback to the server because the contents of the dynamic portion of the questionnaire depend on the selected status. Some questions are always present regardless of status, and yet others may not be present at all for the selected status. The point is, when the status changes, I have to postback to the page and render the right set of questions. Additionally, I need to preserve any user entered values for those questions which are 'always available'. However, due to the page life cycle in ASP.NET, the 'Status' user control's OnLoad, which contains the correct status needed to load the right questions from the DB, doesn't get executed until after the 'dynamic questions' user control has already been populated (with the wrong/stale values). To get around this, I raise an event from my 'Status' user control to the main page to indicate that the Status has changed. The main page then raises an event on the 'dynamic questions' user control. Since by the time this event bubbles up, the 'dynamic questions' user control has already loaded the 'wrong' questions from the DB, it first calls Controls.Clear. It then happily uses the new status to query the database for the 'correct' questions and does a Control.Add() on each. FYI, Control.IDs are consistent across postbacks. This solution works...sorta. The correct set of questions for the selected status do get rendered; however ViewState is getting lost for those 'always available' questions. I'm guessing this is because the 'dynamic questions' user control calls Controls.Clear when responding to the status changed event. This must somehow kill the association between ViewState and my dynamic controls, even though the Control.ID are consistent. This seems like such a common requirement, I'm virtually certain there is a better, cleaner and less error prone approach to accomplish this. In case its not plain obvious, I haven't been able to grok the ASP.NET page life-cycle despite working with it for the last year. Any help is much appreciated!

  • Getting elements children with certain tag jQuery

    - by johnnyArt
    I'm trying to get all the input elements from a certain form from jQuery by providing only the name of the form and only knowing that those wanted fields are input elements. Let's say: <form action='#' id='formId'> <input id='name' /> <input id='surname'/> </form> How do I access them individually with jQuery? I tried something like $('#formId > input') with no success, in fact an error came back on the console "XML filter is applied to non-XML value (function (a, b) {return new (c.fn.init)(a, b);})" Maybe I have to do it with .children or something like that? I'm pretty new at jQuery and I'm not really liking the Docs. It was much friendlier in Mootools, or maybe I just need to get used to it. Oh and last but not least, I've seen it asked before but no final answer, can I create a new dom element with jQuery and work with it before inserting it (if I ever do) into de code? In mootools, we had something like var myEl = new Element(element[, properties]); and you could then refer to it in further expressions, but I fail to understand how to do that on jQuery Thanks in advance.

  • Parse JSON into a ListView friendly output

    - by Thomas McDonald
    So I have this JSON, which then my activity retrieves to a string: {"popular": {"authors_last_month": [ { "url":"http://activeden.net/user/OXYLUS", "item":"OXYLUS", "sales":"1148", "image":"http://s3.envato.com/files/15599.jpg" }, { "url":"http://activeden.net/user/digitalscience", "item":"digitalscience", "sales":"681", "image":"http://s3.envato.com/files/232005.jpg" } { ... } ], "items_last_week": [ { "cost":"4.00", "thumbnail":"http://s3.envato.com/files/227943.jpg", "url":"http://activeden.net/item/christmas-decoration-balls/75682", "sales":"43", "item":"Christmas Decoration Balls", "rating":"3", "id":"75682" }, { "cost":"30.00", "thumbnail":"http://s3.envato.com/files/226221.jpg", "url":"http://activeden.net/item/xml-flip-book-as3/63869", "sales":"27", "item":"XML Flip Book / AS3", "rating":"5", "id":"63869" }, { ... }], "items_last_three_months": [ { "cost":"5.00", "thumbnail":"http://s3.envato.com/files/195638.jpg", "url":"http://activeden.net/item/image-logo-shiner-effect/55085", "sales":"641", "item":"image logo shiner effect", "rating":"5", "id":"55085" }, { "cost":"15.00", "thumbnail":"http://s3.envato.com/files/180749.png", "url":"http://activeden.net/item/banner-rotator-with-auto-delay-time/22243", "sales":"533", "item":"BANNER ROTATOR with Auto Delay Time", "rating":"5", "id":"22243"}, { ... }] } } It can be accessed here as well, although it because it's quite a long string, I've trimmed the above down to display what is needed. Basically, I want to be able to access the items from "items_last_week" and create a list of them - originally my plan was to have the 'thumbnail' on the left with the 'item' next to it, but from playing around with the SDK today it appears too difficult or impossible to achieve this, so I would be more than happy with just having the 'item' data from 'items_last_week' in the list. Coming from php I'm struggling to use any of the JSON libraries which are available to Java, as it appears to be much more than a line of code which I will need to deserialize (I think that's the right word) the JSON, and they all appear to require some form of additional class, apart from the JSONArray/JSONObject script I have which doesn't like the fact that items_last_week is nested (again, I think that's the JSON terminology) and takes an awful long time to run on the Android emulator. So, in effect, I need a (preferably simple) way to pass the items_last_week data to a ListView. I understand I will need a custom adapter which I can probably get my head around but I cannot understand, no matter how much of the day I've just spent trying to figure it out, how to access certain parts of a JSON string..

  • XSLT: need to replace document('')

    - by Daziplqa
    I've the following xslt file: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <!-- USDomesticCountryList - USE UPPERCASE LETTERS ONLY --> <xsl:variable name="USDomesticCountryList"> <entry name="US"/> <entry name="UK"/> <entry name="EG"/> </xsl:variable> <!--// USDomesticCountryList --> <xsl:template name="IsUSDomesticCountry"> <xsl:param name="countryParam"/> <xsl:variable name="country" select="normalize-space($countryParam)"/> <xsl:value-of select="normalize-space(document('')//xsl:variable[@name='USDomesticCountryList']/entry[@name=$country]/@name)"/> </xsl:template> </xsl:stylesheet> I need to replace the "document('')" xpath function, what should I use instead? I've tried to remove it completely but the xsl document doesn't work for me! I need to to so because the problem is : I am using some XSLT document that uses the above file, say document a. So I have document a that includes the above file (document b). I am using doc a from java code, I am do Caching for doc a as a javax.xml.transform.Templates object to prevent multiple reads to the xsl file on every transformation request. I found that, the doc b is re-calling itself from the harddisk, I believe this is because of the document('') function above, so I wanna replace/remove it. Thanks.

  • Servlet Mapping Help - Possible to Avoid Referencing Context Name?

    - by AJ
    Hi all, I am working on a Spring application and trying to get my URL mapping correct. What I would like to have work is the following: http://localhost:8080/idptest -> doesn't work But instead, I have to reference the context name in my URL in order to resolve the mapping: http://localhost:8080/<context_name>/idptest -> works How can I avoid the requirement of referencing the context name in my URL without using a rewrite/proxy engine e.g. Apache? Here is the servlet definition and mapping from my web.xml: <servlet> <servlet-name>idptest</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/conf/idptest.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>idptest</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> Here's the outline of my controller (showing annotations for request mappings): @Controller @RequestMapping("/idptest") public class MyController { @RequestMapping(method=RequestMethod.GET) public String setupForm(Model model){ MyObject someObject = new MyObject(); model.addAttribute("someObject", someObject); return "myform"; } @RequestMapping(method = RequestMethod.POST) public String processSubmit(@ModelAttribute("someObject") MyObject someObject) throws Exception { // POST logic... } } Thanks!

  • Why can't I shrink a transaction log file, even after backup?

    - by Jordan Hudson
    I have a database that has a 28gig transaction log file. Recovery mode is simple. I just took a full backup of the database, and then ran both: backup log dbmcms with truncate_only DBCC SHRINKFILE ('Wxlog0', TRUNCATEONLY) The name of the db is db_mcms and the name of the transaction log file is Wxlog0. Neither has helped. I'm not sure what to do next.

  • Optimzing TSQL code

    - by adopilot
    My job is the maintain one application which heavy use SQL server (MSSQL2005). Until now middle server stores TSQL codes in XML and send dynamic TSQL queries without using stored procs. As I am able change those XML queries I want to migrate most of my queries to stored procs. Question is folowing: Most of my queries have same Where conditions against one table Sample: Select ..... from .... where .... and (a.vrsta_id = @vrsta_id or @vrsta_id = 0) and (a.podvrsta_id = @podvrsta_id or @podvrsta_id = 0) and (a.podgrupa_2 = @podgrupa2_id or @podgrupa2_id = 0) and ( (a.id in (select art_id from osobina_veze where podosobina_id in (select ado from dbo.fn_ado_param_int(@podosobina)) group by art_id having count(art_id)= @podosobina_count )) or ('0' = @podosobina) ) They also have same where conditions on other table. How I should organize my code ? What is proper way ? Should I make table valued function that I will use in all queries or use #Temp tables and simple inner join my query to that each time when proc executing? or use #temp filed by table valued function ? or leave all queries with this large where clause and hope that index is going to do their jobs. or use WITH(statement)

  • Why limit WCF ServiceContracts to 10-20 OperationContracts?

    - by Gary B
    I've seen recommendations (Juval Lowy, et al) that a service contract should have "no more than 20 members...twelve is probably the practical limit". Why? It seems that if you wish to provide a service as the interface to a relatively large db (50-100 tables) you're going to go way past that in just CRUD alone. I've worked with plenty of other services that provided hundreds of 'OperationContracts'...is there something peculiar about WCF? Is there something I'm missing here?
