  • Write DAX queries in Report Builder #ssrs #dax #ssas #tabular

    - by Marco Russo (SQLBI)
    If you use Report Builder with Reporting Services, you can use DAX queries even if the editor for Analysis Services provider does not support DAX syntax. In fact, the DMX editor that you can use in Visual Studio editor of Reporting Services (see a previous post on that), is not available in Report Builder. However, as Sagar Salvi commented in this Microsoft Connect entry, you can use the DAX query text in the query of a Dataset by using the OLE DB provider instead of the Analysis Services one. I think it’s a good idea to show the steps required. First, create a DataSet using the OLE DB connection type, and provide the connection string the provider (Provider), the server name (Data Source) and the database name (Initial Catalog), such as: Provider=MSOLAP;Data Source=SERVERNAME\\TABULAR;Initial Catalog=AdventureWorks Tabular Model SQL 2012 Then, create a Dataset using the data source previously defined, select the Text query type, and write the DAX code in the Query pane: You can also use the Query Designer window, that doesn’t provide any particular help in writing the DAX query, but at least can show a preview of the result of the query execution. I hope DAX will get better editors in the future… in the meantime, remember you can use DAX Studio to write and test your DAX queries, and DAX Formatter to improve their readability!If you want to learn the DAX Query Language, I suggest you watching my video Data Analysis Expressions as a Query Language on Project Botticelli!

  • One of my most frequently used commands

    - by Kevin Smith
    On a Linux or UNIX server this is one of my most frequently used commands. find . -name "*.htm" -exec grep -iH "alter session" {} \; It is an easy way to find a string you know is in a group of files, but don't know or can't remember which file it is in. For the example above, I knew that WebCenter Content sends a bunch of alter session commands to the database when it opens a new database connection. I wanted to find where these were defined and what all the alter session commands were. So, I ran these commands: cd /opt/oracle/middleware/Oracle_ECM1/ucm/idc/resources/core find . -name "*.htm" -exec grep -iH "alter session" {} \; And the results were: ./tables/query.htm: ALTER SESSION SET optimizer_mode = ?./tables/query.htm: ALTER SESSION SET NLS_LENGTH_SEMANTICS = ?./tables/query.htm: ALTER SESSION SET NLS_SORT = ?./tables/query.htm: ALTER SESSION SET NLS_COMP = ?./tables/query.htm: ALTER SESSION SET CURSOR_SHARING = ?./tables/query.htm: ALTER SESSION SET EVENTS '30579 trace name context forever, level 2'./tables/query.htm: ALTER SESSION SET NLS_DATE_FORMAT = ?./tables/query.htm: alter session set events '30579 trace name context forever, level 2' I could then go edit the query.htm file and find the include that contained all the ALTER SESSION commands.

  • Fingerprint of PEM ssh key

    - by Unknown
    I have a PEM file which I add to a running ssh-agent: $ file query.pem query.pem: PEM RSA private key $ ssh-add ./query.pem Identity added: ./query.pem (./query.pem) $ ssh-add -l | grep query 2048 ef:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX ./query.pem (RSA) My question is how I can get the key fingerprint I see in ssh-agent directly from the file. I know ssh-keygen -l -f some_key works for "normal" ssh keys, but not for PEM files. If I try ssh-keygen on the .pem file, I get: $ ssh-keygen -l -f ./query.pem key_read: uudecode PRIVATE KEY----- failed key_read: uudecode PRIVATE KEY----- failed ./query.pem is not a public key file. This key starts with: -----BEGIN RSA PRIVATE KEY----- MIIEp.... etc. as opposed to a "regular" private key, which looks like: -----BEGIN RSA PRIVATE KEY----- Proc-Type: 4,ENCRYPTED DEK-Info: AES-128-CBC,E15F2.... etc.

  • How to 301 redirect from old query string urls to CakePHP Canonical urls?

    - by Daniel Bingham
    I currently have a .htaccess file that looks like this: RewriteCond %{QUERY_STRING} ^action=view&item=([0-9]+)$ RewriteRule ^index\.php$ /index.php?url=item/%1 [R=301] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [QSA,L] It is meant to 301 redirect my old query string based URLs to new CakePHP urls. This will successfully send users to the correct page. However, Google doesn't seem to like it (see below). I previously tried doing this: RewriteCond %{QUERY_STRING} ^action=view&item=([0-9]+)$ RewriteRule ^index\.php$ /item/%1 [R=301] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [QSA,L] But that fails. The second rewrite rule doesn't seem to catch the rewritten URL. It goes straight through. Using the first version wouldn't be a problem, except that I suspect that is what is choking up Google. It hasn't indexed my sitemap full of the new URLs. My old sitemap had been fully indexed and all the URLs are in Google's index. But it isn't following the redirects from the old URLs to the new. I have a 'not followed' error for every one of the query urls that was in my old sitemap. Am I properly using a 301 redirect here? Is it the weird rewrite rule? What can I do to send both Google and users to the proper page and save my page rank?

  • What should I call the process of converting an object to a string?

    - by shabbychef
    We are having a game of 'semantic football' in the office over this matter: I am writing a method for an object which will represent the object as a string. That string should be such that when typed (more likely, cut and pasted) into the interpreter window (I will keep the language name out of this for now), will produce an object which is, for our purposes, identical to the one upon which the method was called. There is a spirited discussion over the 'best' name for this method. The terms pickle, serialize, deflate, etc have been proposed. However, it seems that those terms assume some process for the de-pickling (unserialization, etc) that is not necessarily the language interpreter itself. That is, they do not specifically refer to the case where strings of valid code are produced. This is closer to a quine, but we are re-producing the object not the code, so this is not quite right. any suggestions?

  • Generalise variable usage inside code

    - by Shirish11
    I would like to know if it is a good practice to generalize variables (use single variable to store all the values). Consider simple example Strings querycre,queryins,queryup,querydel; querycre = 'Create table XYZ ...'; execute querycre ; queryins = 'Insert into XYZ ...'; execute queryins ; queryup = 'Update XYZ set ...'; execute queryup; querydel = 'Delete from XYZ ...'; execute querydel ; and Strings query; query= 'Create table XYZ ... '; execute query ; query= 'Insert into XYZ ...'; execute query ; query= 'Update XYZ set ...'; execute query ; query= 'Delete from XYZ ...'; execute query ; In first case I use 4 strings each storing data to perform the actions mentioned in their suffixes. In second case just 1 variable to store all kinds the data. Having different variables makes it easier for someone else to read and understand it better. But having too many of them makes it difficult to manage. Also does having too many variables hamper my performance?

  • How to choose between Tell don't Ask and Command Query Separation?

    - by Dakotah North
    The principle Tell Don't Ask says: you should endeavor to tell objects what you want them to do; do not ask them questions about their state, make a decision, and then tell them what to do. The problem is that, as the caller, you should not be making decisions based on the state of the called object that result in you then changing the state of the object. The logic you are implementing is probably the called object’s responsibility, not yours. For you to make decisions outside the object violates its encapsulation. A simple example of "Tell, don't Ask" is Widget w = ...; if (w.getParent() != null) { Panel parent = w.getParent(); parent.remove(w); } and the tell version is ... Widget w = ...; w.removeFromParent(); But what if I need to know the result from the removeFromParent method? My first reaction was just to change the removeFromParent to return a boolean denoting if the parent was removed or not. But then I came across Command Query Separation Pattern which says NOT to do this. It states that every method should either be a command that performs an action, or a query that returns data to the caller, but not both. In other words, asking a question should not change the answer. More formally, methods should return a value only if they are referentially transparent and hence possess no side effects. Are these two really at odds with each other and how do I choose between the two? Do I go with the Pragmatic Programmer or Bertrand Meyer on this?

  • Convention location for JAR files for a LaunchDaemon on OS X?

    I'm setting up a Hudson build slave on an OS X machine. I'm using launchd to start the slave using the following plist in `/Library/LaunchDaemons/': <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>KeepAlive</key> <true/> <key>Label</key> <string>org.hudson-ci.jnlpslave</string> <key>ProgramArguments</key> <array> <string>/usr/bin/java</string> <string>-jar</string> <string>/Users/Shared/Hudson/slave.jar</string> <string>-noCertificateCheck</string> <string>-jnlpUrl</string> <string>file:///Users/Shared/Hudson/slave-agent.jnlp</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> I'm currently putting the slave.jar and slave-agent.jnlp files in /Users/Shared/Hudson but this seems like an unnecessarily user-visible location.

  • VB.NET handling data between different forms

    - by niuchu
    Hi, I'm writing a simple application - address book. User enters new addresses and they are added as an entry to a list visible on the main form (frmStart). I use one form to add and edit (AddContForm). Add button on the frmStart works fine, however I experience some problems with the edit button as when I press it and enter new data they are added as new entry however the previous entry is still there. Logic is handled by Contact.vb class. Please let me know how to fix this problem. Here is the code: Contact.vb Public Class Contact Public Contact As String Public Title As String Public Fname As String Public Surname As String Public Address As String Private myCont As String Public Property Cont() Get Return myCont End Get Set(ByVal value) myCont = Value End Set End Property Public Overrides Function ToString() As String Return Me.Cont End Function Public Sub Display() Dim C As New Contact C.Cont = frmAddCont.txtTitle.Text C.Fname = frmAddCont.txtFName.Text C.Surname = frmAddCont.txtSName.Text C.Address = frmAddCont.txtAddress.Text frmStart.lstContact.Items.Add(C) End Sub End Class Here is frmStart.vb Public Class frmStart Public Button As String Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click Button = "" Button = "Add" frmAddCont.ShowDialog() End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDel.Click Button = "" Button = "Del" Dim DelCont As Contact DelCont = Me.lstContact.SelectedItem() lstContact.Items.Remove(DelCont) End Sub Private Sub lstContact_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstContact.SelectedIndexChanged End Sub Private Sub btnEdit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEdit.Click Button = "" Button = "Edit" Dim C As Contact If lstContact.SelectedItem IsNot Nothing Then C = DirectCast(lstContact.SelectedItem, Contact) frmAddCont.ShowDialog() End If End Sub End Class Here is AddContFrm.vb Public Class frmAddCont Public Class ControlObject Dim Title As String Dim FName As String Dim SName As String Dim Address As String Dim TelephoneNumber As Integer Dim emailAddress As String Dim Website As String Dim Photograph As String End Class Private Sub btnConfirmAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnConfirmAdd.Click Dim B As String B = frmStart.Button Dim C As New Contact C.Display() Me.Hide() If B = "Edit" Then C = DirectCast(frmStart.lstContact.SelectedItem, Contact) frmStart.lstContact.SelectedItems.Remove(C) End If End Sub Private Sub frmAddCont_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub End Class

  • Is there a significant mechanical difference between these faux simulations of default parameters?

    - by ccomet
    C#4.0 introduced a very fancy and useful thing by allowing default parameters in methods. But C#3.0 doesn't. So if I want to simulate "default parameters", I have to create two of that method, one with those arguments and one without those arguments. There are two ways I could do this. Version A - Call the other method public string CutBetween(string str, string left, string right, bool inclusive) { return str.CutAfter(left, inclusive).CutBefore(right, inclusive); } public string CutBetween(string str, string left, string right) { return CutBetween(str, left, right, false); } Version B - Copy the method body public string CutBetween(string str, string left, string right, bool inclusive) { return str.CutAfter(left, inclusive).CutBefore(right, inclusive); } public string CutBetween(string str, string left, string right) { return str.CutAfter(left, false).CutBefore(right, false); } Is there any real difference between these? This isn't a question about optimization or resource usage or anything (though part of it is my general goal of remaining consistent), I don't even think there is any significant effect in picking one method or the other, but I find it wiser to ask about these things than perchance faultily assume.

  • JSON feed to Java Object

    - by mnml
    Hi, I would like to know if there is a webpage/software that can "translate" a Json feed object to a Java object with attributes. For example : { 'firstName': 'John', 'lastName': 'Smith', 'address': { 'streetAddress': '21 2nd Street', 'city': 'New York' } } Would become: class Person { private String firstName; private String lastName; private Address address; public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public Address getAddress() { return address; } public void setFirstName(String firstName) { this.firstName = firstName; } public void setLastName(String lastName) { this.lastName = lastName; } public void setAddress(Address address) { this.address = address; } public String toString() { return String.format("firstName: %s, lastName: %s, address: [%s]", firstName, lastName, address); } } class Address { private String streetAddress; private String city; public String getStreetAddress() { return streetAddress; } public String getCity() { return city; } public void setStreetAddress(String streetAddress) { this.streetAddress = streetAddress; } public void setCity(String city) { this.city = city; } public String toString() { return String.format("streetAddress: %s, city: %s", streetAddress, city); } } I'm not asking that because I'm lazy, but the JSON I would like to parse has quite a lot of attribute.

  • php simplexmlelement - I can access most properties (except the one with a dash?)

    - by Matthew Steiner
    So I run some code like this: $quote = simplexml_load_string($xml); $quote = $quote->Stock; echo 'Name: '; echo $quote->Name; echo '<br>'; echo 'Sybmol: '; echo $quote->Symbol; echo '<br>'; echo 'Last Price: '; echo $quote->Last; echo '<br>'; echo 'Earnings To Price Ratio: '; echo $quote->P-E; echo '<br>'; I know that the second to last line ($quote-P-E) is incorrect - I don't think you can use dashes like that. But for some reason I can't figure out how to access that property. The weird thing is that's how it's written if I var_dump($quote) (It's towards the end): object(SimpleXMLElement)#17 (16) { ["Symbol"]=> string(4) "AAPL" ["Last"]=> string(6) "271.87" ["Date"]=> string(9) "6/17/2010" ["Time"]=> string(6) "3:59pm" ["Change"]=> string(5) "+4.62" ["Open"]=> string(6) "270.72" ["High"]=> string(6) "272.90" ["Low"]=> string(6) "269.50" ["Volume"]=> string(8) "31195032" ["MktCap"]=> string(6) "247.4B" ["PreviousClose"]=> string(6) "267.25" ["PercentageChange"]=> string(6) "+1.73%" ["AnnRange"]=> string(15) "132.88 - 272.90" ["Earns"]=> string(6) "11.796" ["P-E"]=> string(5) "22.66" ["Name"]=> string(10) "Apple Inc." } How should I be accessing this attribute/property?

Extraction Blacklist cpf list. where ExtrOcamlString I opened: open Cpf0;; in problem.ml, and I got a new problem because in problem.ml they have another definition for type string This expression has type Cpf0.string = char list but an expression was expected of type Util.StrSet.elt = string Here is a definition in util.ml defined type string: module Str = struct type t = string end;; module StrOrd = Ord.Make (Str);; module StrSet = Set.Make (StrOrd);; module StrMap = Map.Make (StrOrd);; let set_add_chk x s = if StrSet.mem x s then failwith (x ^ " already declared") else StrSet.add x s;; I was trying to change t = string to t = char list, but if I do that I have to change a lot of function it depend on (for example: set_add_chk above). Could you please give me a good idea? how I would do in this case.

  • How to reduce Entity Framework 4 query compile time?

    - by Rup
    Summary: We're having problems with EF4 query compilation times of 12+ seconds. Cached queries will only get us so far; are there any ways we can actually reduce the compilation time? Is there anything we might be doing wrong we can look for? Thanks! We have an EF4 model which is exposed over the WCF services. For each of our entity types we expose a method to fetch and return the whole entity for display / edit including a number of referenced child objects. For one particular entity we have to .Include() 31 tables / sub-tables to return all relevant data. Unfortunately this makes the EF query compilation prohibitively slow: it takes 12-15 seconds to compile and builds a 7,800-line, 300K query. This is the back-end of a web UI which will need to be snappier than that. Is there anything we can do to improve this? We can CompiledQuery.Compile this - that doesn't do any work until first use and so helps the second and subsequent executions but our customer is nervous that the first usage shouldn't be slow either. Similarly if the IIS app pool hosting the web service gets recycled we'll lose the cached plan, although we can increase lifetimes to minimise this. Also I can't see a way to precompile this ahead of time and / or to serialise out the EF compiled query cache (short of reflection tricks). The CompiledQuery object only contains a GUID reference into the cache so it's the cache we really care about. (Writing this out it occurs to me I can kick off something in the background from app_startup to execute all queries to get them compiled - is that safe?) However even if we do solve that problem, we build up our search queries dynamically with LINQ-to-Entities clauses based on which parameters we're searching on: I don't think the SQL generator does a good enough job that we can move all that logic into the SQL layer so I don't think we can pre-compile our search queries. This is less serious because the search data results use fewer tables and so it's only 3-4 seconds compile not 12-15 but the customer thinks that still won't really be acceptable to end-users. So we really need to reduce the query compilation time somehow. Any ideas? Profiling points to ELinqQueryState.GetExecutionPlan as the place to start and I have attempted to step into that but without the real .NET 4 source available I couldn't get very far, and the source generated by Reflector won't let me step into some functions or set breakpoints in them. The project was upgraded from .NET 3.5 so I have tried regenerating the EDMX from scratch in EF4 in case there was something wrong with it but that didn't help. I have tried the EFProf utility advertised here but it doesn't look like it would help with this. My large query crashes its data collector anyway. I have run the generated query through SQL performance tuning and it already has 100% index usage. I can't see anything wrong with the database that would cause the query generator problems. Is there something O(n^2) in the execution plan compiler - is breaking this down into blocks of separate data loads rather than all 32 tables at once likely to help? Setting EF to lazy-load didn't help. I've bought the pre-release O'Reilly Julie Lerman EF4 book but I can't find anything in there to help beyond 'compile your queries'. I don't understand why it's taking 12-15 seconds to generate a single select across 32 tables so I'm optimistic there's some scope for improvement! Thanks for any suggestions! We're running against SQL Server 2008 in case that matters and XP / 7 / server 2008 R2 using RTM VS2010.

  • Same SELECT used in an INSERT has different execution plan

    A customer complained that a query and its INSERT counterpart had different execution plans, and of course, the INSERT was slower. First lets look at the SELECT : SELECT ua_tr_rundatetime,        ua_ch_treatmentcode,        ua_tr_treatmentcode,        ua_ch_cellid,        ua_tr_cellid FROM   (SELECT DISTINCT CH.treatmentcode AS UA_CH_TREATMENTCODE,                         CH.cellid        AS UA_CH_CELLID         FROM    CH,                 DL         WHERE  CH.contactdatetime > SYSDATE - 5                AND CH.treatmentcode = DL.treatmentcode) CH_CELLS,        (SELECT DISTINCT T.treatmentcode AS UA_TR_TREATMENTCODE,                         T.cellid        AS UA_TR_CELLID,                         T.rundatetime   AS UA_TR_RUNDATETIME         FROM    T,                 DL         WHERE  T.treatmentcode = DL.treatmentcode) TRT_CELLS WHERE  CH_CELLS.ua_ch_treatmentcode(+) = TRT_CELLS.ua_tr_treatmentcode;  The query has 2 DISTINCT subqueries.  The execution plan shows one with DISTICT Placement transformation applied and not the other.

  • Monotouch - ICSharpCode.SharpZipLib giving an error

  • "ResolveAssemblyReference" task fails and System.BadImageFormatException, but assembly isn't used an

    - by bdwakefield
    I am getting an error about the assembly "C:\Ora10g\bin\Zip.exe". The trouble is this solution does NOT use anything in Oracle at all. I could not find a single reference to 10g anywhere in the project. I inherited this from another person who left our group. He never had this issue. Another member of my team said he got this before but reinstalling the client portion of 10g fixed it. No such luck there. I even tried using WinGrep to search the entire solution folder for "Ora10g" but it wasn't there. Any ideas? I can't build this solution until I can figure out how to get rid of this false reference to Oracle. VS 2005 solution. Contains a couple WinForm apps, a couple class libraries, and a web service. The error occurs in the main class library project. Here is the error message: Error 1 The "ResolveAssemblyReference" task failed unexpectedly.
