  • Margin totals in xtabs

    - by James
    If you have 2 cross classifying variables you can use rowSums and colSums to produce margin totals on an xtabs output. But how can it be done if you have 3 classifying variables (ie margin totals in each sub table)?

  • How to "scan" a website (or page) for info, and bring it into my program?

    - by James
    Well, I'm pretty much trying to figure out how to pull information from a webpage, and bring it into my program (in Java). For example, if I know the exact page I want info from, for the sake of simplicity a Best Buy item page, how would I get the appropriate info I need off of that page? Like the title, price, description? What would this process even be called? I have no idea were to even begin researching this.

  • Is there a way to redirect ONLY stderr to stdout (not combine the two) so it can be piped to other programs

    - by James K
    I'm working in a Windows CMD.EXE environment and would like to change the output of stdout to match that of stderr so that I can pipe error messages to other programs without the intermediary of a file. I'm aware of the 2>&1 notation, but that combines stdout and stderr into a single stream. What I'm thinking of would be something like this: program.exe 2>&1 | find " " But that combines stdout and stderr just like: program.exe | find " " 2>&1 I realize that I could do... program 2>file type file | find " " del file But this does not have the flexibility and power of a program | find " " sort of notation. Doing this requires that program has finished with it's output before that output can be processed.

  • Stop a user directly accesing a page

    - by James Jeffery
    I have a page called create.php. It receives post variables and sets up accounts. I don't want that page to be accessible by a user. What's the conventional way of achieving this? I think I remember reading something about including a page with a CONSTANT. If the CONSTANT is not present the page has been accessed directly. I think Wordpress also do it.

  • Questions about "sets"

    - by James
    I have a test tomorrow that I am revising for and the lecturer has supplied some sample questions with no answers. I was hoping I could get some help with a couple of them. I've written what I think the answer is for them. 1. What is the type of the set {1, 2, 3}? integer/number 2. What is the type of the set {{1}, {2}, {3}}? integer/number (unsure what putting each number in {} does?) 3. What is the type of the set {{1}, {2}, {3}, empty}? integer/number 4. What is the type of the set {1, {2}, 3}? — is it well typed? integer/number 5. What is the type of the set {1, 2, john}? — is it well typed? unsure for a mixed set. Taking a complete guess of void or empty. Any help will be much appreciated.

  • How do submit an object to a struts2 action using jQuery?

    - by James Drinkard
    I have an object that I'm populating from a selection off a table row that a user selects. I have a jQuery function that captures the click event and a hidden form field populates an id I need. However, I'm not sure as to the proper way to send off that object to a struts2 action? I tried using this: $(function() { $('#tbl tr').click(function() { var id = $(this).closest('tr').find('input:hidden').val(); var page = "<s:url action='update/deleteInfo.action'/>?model.isDelete=true&model.info.id=id"; console.log(page); window.location.href=(page); }); }); The model object has an isDelete boolean variable and the model has a nested info object that has an id variable with getter/setters. However, when I send this across, the model object isn't populated with these entries. Is there a way to do this or a better way than the url tag?

  • Using .htaccess to change my website URLs

    - by James P
    I have some pages organised like this: http://localhost/index.html http://localhost/download.html http://localhost/contact.html And I need them changed to suit the following URL structure: http://localhost/ http://localhost/download http://localhost/contact Without making sub directories and putting in pages as index.html. As far as I know .htaccess can be used for this, but I have no idea what I need to add to my .htaccess file to make this work. Can anyone provide some help? Thanks.

  • Resized XIB still full size

    - by James
    Building an iPad app. I have a button on my main view that I want to launch a help window. The help window is fairly involved and has its own xib/controller. I resized the help window's XIB and saved it. I instantiated it and added it to the application controller's views as a modal. For some reason this window is still taking up the entire screen. What I really want to do is have a "view" that's maybe 70% of the width and height that lays over the normal view as a modal. How is this accomplished normally? I want it to require that they hit a button to close it. Thanks

  • How can I dynamically resize the jQuery Colorbox plugin?

    - by James Skidmore
    The AJAX content loaded in a Colorbox has some JavaScript included that resizes things within the content. Colorbox determines its sizing based on the sizes before all of the AJAX happens. How can I make the Colorbox resize after the content has been loaded? Here is a link where someone said that you can call colorbox() again after it's been loaded, but I can't figure out how to do that: http://groups.google.com/group/colorbox/browse_thread/thread/535d21c69e9006b0

  • Why isn't this working - using :not() with an event handler

    - by james emanon
    I seem to have another issue that I am not conquering. Real simple premise. I have a mousedown event, and basically IF one particular element on the page is clicked, I want nothing to happen, else I want hide() some div. $(function(){ $("document :not(#_ignorelement)").mousedown(function(event){ if($('#_hidethiselement').length){ $('#_hidethiselement').hide(); } }) }) That is not working at all. I also tried the following: $(document).not($("#_ignorelement")).mousedown(function(event){ $(document).not("_ignorelement").mousedown(function(event){ IF I can solve that, curious how I would actually have ":not" encompass the parent div, like so: $().not("_ignoreelement").parent().closest('div').mousedown(function Because the element "_ignorelement" is an anchor tag that is in a div. Wonder how I can use the parent div perhaps, instead of the anchor tag. Anyways, any help would be appreciated.

  • Performing an operation based on values within an array

    - by James W.
    I'm trying to figure out how to do operations based on values in an array. The values are taken from a string and inserted into the array e.g num = TextBox.Text.Split(' '); results = Convert.ToDouble(num[0]); for (int i = 0; i < num.Length - 1; i++) { if (num[i] == "+") { results += Convert.ToDouble(num[i++]); } ... } So based on this, let's say the TextBox string value was "1 + 2". So the array would be: ------------- | 1 | + | 2 | ------------- 0 1 2 (indexes) The part I'm having trouble with is Convert.ToDouble(num[i++]).. I've tried num[1] + 1, num[i + 1], etc I'm trying to figure out how to get it to perform the operation based on the first value and the value in the index after the operator. Which is the correct way to do something like this?

  • Auth-Type :- Reject in RADIUS users file matches inner tunnel request but sends Access-Accept

    - by mgorven
    I have WPA2 802.11x EAP authentication setup using FreeRADIUS 2.1.8 on Ubuntu 10.04.4 talking to OpenLDAP, and can successfully authenticate using PEAP/MSCHAPv2, TTLS/MSCHAPv2 and TTLS/PAP (both via the AP and using eapol_test). I am now trying to restrict access to specific SSIDs based on the LDAP groups which the user belongs to. I have configured group membership checking in /etc/freeradius/modules/ldap like so: groupname_attribute = cn groupmembership_filter = "(|(&(objectClass=posixGroup)(memberUid=%{User-Name}))(&(objectClass=posixGroup)(uniquemember=%{User-Name})))" and I have configured extraction of the SSID from Called-Station-Id into Called-Station-SSID based on the Mac Auth wiki page. In /etc/freeradius/eap.conf I have enabled copying attributes from the outer tunnel into the inner tunnel, and usage of the inner tunnel response in the outer tunnel (for both PEAP and TTLS). I had the same behaviour before changing these options however. copy_request_to_tunnel = yes use_tunneled_reply = yes I'm running eapol_test like this to test the setup: eapol_test -c peap-mschapv2.conf -a 172.16.0.16 -s testing123 -N 30:s:01-23-45-67-89-01:Example-EAP with the following peap-mschapv2.conf file: network={ ssid="Example-EAP" key_mgmt=WPA-EAP eap=PEAP identity="mgorven" anonymous_identity="anonymous" password="foobar" phase2="autheap=MSCHAPV2" } With the following in /etc/freeradius/users: DEFAULT Ldap-Group == "employees" and running freeradius-Xx, I can see that the LDAP group retrieval works, and that the SSID is extracted. Debug: [ldap] performing search in dc=example,dc=com, with filter (&(cn=employees)(|(&(objectClass=posixGroup)(memberUid=mgorven))(&(objectClass=posixGroup)(uniquemember=mgorven)))) Debug: rlm_ldap::ldap_groupcmp: User found in group employees ... Info: expand: %{7} -> Example-EAP Next I try to only allow access to users in the employees group (regardless of SSID), so I put the following in /etc/freeradius/users: DEFAULT Ldap-Group == "employees" DEFAULT Auth-Type := Reject But this immediately rejects the Access-Request in the outer tunnel because the anonymous user is not in the employees group. So I modify it to only match inner tunnel requests like so: DEFAULT Ldap-Group == "employees" DEFAULT FreeRADIUS-Proxied-To == "127.0.0.1" Auth-Type := Reject, Reply-Message = "User does not belong to any groups which may access this SSID." Now users which are in the employees group are authenticated, but so are users which are not in the employees group. I see the reject entry being matched, and the Reply-Message is set, but the client receives an Access-Accept. Debug: rlm_ldap::ldap_groupcmp: Group employees not found or user is not a member. Info: [files] users: Matched entry DEFAULT at line 209 Info: ++[files] returns ok ... Auth: Login OK: [mgorven] (from client test port 0 cli 02-00-00-00-00-01 via TLS tunnel) Info: WARNING: Empty section. Using default return values. ...

  • NHibernate Pitfalls: Fetch and Paging

    - by Ricardo Peres
    This is part of a series of posts about NHibernate Pitfalls. See the entire collection here. NHibernate allows you to force loading additional references (many to one, one to one) or collections (one to many, many to many) in a query. You must know, however, that this is incompatible with paging. It’s easy to see why. Let’s say you want to get 5 products starting on the fifth, you can issue the following LINQ query: 1: session.Query<Product>().Take(5).Skip(5).ToList(); Will product this SQL in SQL Server: 1: SELECT 2: TOP (@p0) product1_4_, 3: name4_, 4: price4_ 5: FROM 6: (select 7: product0_.product_id as product1_4_, 8: product0_.name as name4_, 9: product0_.price as price4_, 10: ROW_NUMBER() OVER( 11: ORDER BY 12: CURRENT_TIMESTAMP) as __hibernate_sort_row 13: from 14: product product0_) as query 15: WHERE 16: query.__hibernate_sort_row > @p1 17: ORDER BY If, however, you wanted to bring as well the associated order details, you might be tempted to try this: 1: session.Query<Product>().Fetch(x => x.OrderDetails).Take(5).Skip(5).ToList(); Which, in turn, will produce this SQL: 1: SELECT 2: TOP (@p0) product1_4_0_, 3: order1_3_1_, 4: name4_0_, 5: price4_0_, 6: order2_3_1_, 7: product3_3_1_, 8: quantity3_1_, 9: product3_0__, 10: order1_0__ 11: FROM 12: (select 13: product0_.product_id as product1_4_0_, 14: orderdetai1_.order_detail_id as order1_3_1_, 15: product0_.name as name4_0_, 16: product0_.price as price4_0_, 17: orderdetai1_.order_id as order2_3_1_, 18: orderdetai1_.product_id as product3_3_1_, 19: orderdetai1_.quantity as quantity3_1_, 20: orderdetai1_.product_id as product3_0__, 21: orderdetai1_.order_detail_id as order1_0__, 22: ROW_NUMBER() OVER( 23: ORDER BY 24: CURRENT_TIMESTAMP) as __hibernate_sort_row 25: from 26: product product0_ 27: left outer join 28: order_detail orderdetai1_ 29: on product0_.product_id=orderdetai1_.product_id 30: ) as query 31: WHERE 32: query.__hibernate_sort_row > @p1 33: ORDER BY 34: query.__hibernate_sort_row; However, because of the JOIN, what happens is that, if your products have more than one order details, you will get several records – one per order detail – per product, which means that pagination will be broken. There is an workaround, which forces you to write your LINQ query in another way: 1: session.Query<OrderDetail>().Where(x => session.Query<Product>().Select(y => y.ProductId).Take(5).Skip(5).Contains(x.Product.ProductId)).Select(x => x.Product).ToList() Or, using HQL: 1: session.CreateQuery("select od.Product from OrderDetail od where od.Product.ProductId in (select p.ProductId from Product p skip 5 take 5)").List<Product>(); The generated SQL will then be: 1: select 2: product1_.product_id as product1_4_, 3: product1_.name as name4_, 4: product1_.price as price4_ 5: from 6: order_detail orderdetai0_ 7: left outer join 8: product product1_ 9: on orderdetai0_.product_id=product1_.product_id 10: where 11: orderdetai0_.product_id in ( 12: SELECT 13: TOP (@p0) product_id 14: FROM 15: (select 16: product2_.product_id, 17: ROW_NUMBER() OVER( 18: ORDER BY 19: CURRENT_TIMESTAMP) as __hibernate_sort_row 20: from 21: product product2_) as query 22: WHERE 23: query.__hibernate_sort_row > @p1 24: ORDER BY 25: query.__hibernate_sort_row); Which will get you what you want: for 5 products, all of their order details.

  • Backup Meta-Data

    - by BuckWoody
    I'm working on a PowerShell script to show me the trending durations of my backup activities. The first thing I need is the data, so I looked at the Standard Reports in SQL Server Management Studio, and found a report that suited my needs, so I pulled out the script that it runs and modified it to this T-SQL Script. A few words here - you need to be in the MSDB database for this to run, and you can add a WHERE clause to limit to a database, timeframe, type of backup, whatever. For that matter, I won't use all of the data in this query in my PowerShell script, but it gives me lots of avenues to graph: SELECT distinct t1.name AS 'DatabaseName' ,(datediff( ss,  t3.backup_start_date, t3.backup_finish_date)) AS 'DurationInSeconds' ,t3.user_name AS 'UserResponsible' ,t3.name AS backup_name ,t3.description ,t3.backup_start_date ,t3.backup_finish_date ,CASE WHEN t3.type = 'D' THEN 'Database' WHEN t3.type = 'L' THEN 'Log' WHEN t3.type = 'F' THEN 'FileOrFilegroup' WHEN t3.type = 'G' THEN 'DifferentialFile' WHEN t3.type = 'P' THEN 'Partial' WHEN t3.type = 'Q' THEN 'DifferentialPartial' END AS 'BackupType' ,t3.backup_size AS 'BackupSizeKB' ,t6.physical_device_name ,CASE WHEN t6.device_type = 2 THEN 'Disk' WHEN t6.device_type = 102 THEN 'Disk' WHEN t6.device_type = 5 THEN 'Tape' WHEN t6.device_type = 105 THEN 'Tape' END AS 'DeviceType' ,t3.recovery_model  FROM sys.databases t1 INNER JOIN backupset t3 ON (t3.database_name = t1.name )  LEFT OUTER JOIN backupmediaset t5 ON ( t3.media_set_id = t5.media_set_id ) LEFT OUTER JOIN backupmediafamily t6 ON ( t6.media_set_id = t5.media_set_id ) ORDER BY backup_start_date DESC I'll munge this into my Excel PowerShell chart script tomorrow. Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system.

  • SQL SERVER – Find Referenced or Referencing Object in SQL Server using sys.sql_expression_dependencies

    - by pinaldave
    A very common question which I often receive are: How do I find all the tables used in a particular stored procedure? How do I know which stored procedures are using a particular table? Both are valid question but before we see the answer of this question – let us understand two small concepts – Referenced and Referencing. Here is the sample stored procedure. CREATE PROCEDURE mySP AS SELECT * FROM Sales.Customer GO Reference: The table Sales.Customer is the reference object as it is being referenced in the stored procedure mySP. Referencing: The stored procedure mySP is the referencing object as it is referencing Sales.Customer table. Now we know what is referencing and referenced object. Let us run following queries. I am using AdventureWorks2012 as a sample database. If you do not have SQL Server 2012 here is the way to get SQL Server 2012 AdventureWorks database. Find Referecing Objects of a particular object Here we are finding all the objects which are using table Customer in their object definitions (regardless of the schema). USE AdventureWorks GO SELECT referencing_schema_name = SCHEMA_NAME(o.SCHEMA_ID), referencing_object_name = o.name, referencing_object_type_desc = o.type_desc, referenced_schema_name, referenced_object_name = referenced_entity_name, referenced_object_type_desc = o1.type_desc, referenced_server_name, referenced_database_name --,sed.* -- Uncomment for all the columns FROM sys.sql_expression_dependencies sed INNER JOIN sys.objects o ON sed.referencing_id = o.[object_id] LEFT OUTER JOIN sys.objects o1 ON sed.referenced_id = o1.[object_id] WHERE referenced_entity_name = 'Customer' The above query will return all the objects which are referencing the table Customer. Find Referenced Objects of a particular object Here we are finding all the objects which are used in the view table vIndividualCustomer. USE AdventureWorks GO SELECT referencing_schema_name = SCHEMA_NAME(o.SCHEMA_ID), referencing_object_name = o.name, referencing_object_type_desc = o.type_desc, referenced_schema_name, referenced_object_name = referenced_entity_name, referenced_object_type_desc = o1.type_desc, referenced_server_name, referenced_database_name --,sed.* -- Uncomment for all the columns FROM sys.sql_expression_dependencies sed INNER JOIN sys.objects o ON sed.referencing_id = o.[object_id] LEFT OUTER JOIN sys.objects o1 ON sed.referenced_id = o1.[object_id] WHERE o.name = 'vIndividualCustomer' The above query will return all the objects which are referencing the table Customer. I am just glad to write above query. There are more to write to this subject. In future blog post I will write more in depth about other DMV which also aids in finding referenced data.

  • SQL SERVER – SSMS Automatically Generates TOP (100) PERCENT in Query Designer

    - by pinaldave
    Earlier this week, I was surfing various SQL forums to see what kind of help developer need in the SQL Server world. One of the question indeed caught my attention. I am here regenerating complete question as well scenario to illustrate the point in a precise manner. Additionally, I have added added second part of the question to give completeness. Question: I am trying to create a view in Query Designer (not in the New Query Window). Every time I am trying to create a view it always adds  TOP (100) PERCENT automatically on the T-SQL script. No matter what I do, it always automatically adds the TOP (100) PERCENT to the script. I have attempted to copy paste from notepad, build a query and a few other things – there is no success. I am really not sure what I am doing wrong with Query Designer. Here is my query script: (I use AdventureWorks as a sample database) SELECT Person.Address.AddressID FROM Person.Address INNER JOIN Person.AddressType ON Person.Address.AddressID = Person.AddressType.AddressTypeID ORDER BY Person.Address.AddressID This script automatically replaces by following query: SELECT TOP (100) PERCENT Person.Address.AddressID FROM Person.Address INNER JOIN Person.AddressType ON Person.Address.AddressID = Person.AddressType.AddressTypeID ORDER BY Person.Address.AddressID However, when I try to do the same from New Query Window it works totally fine. However, when I attempt to create a view of the same query it gives following error. Msg 1033, Level 15, State 1, Procedure myView, Line 6 The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified. It is pretty clear to me now that the script which I have written seems to need TOP (100) PERCENT, so Query . Why do I need it? Is there any work around to this issue. I particularly find this question pretty interesting as it really touches the fundamentals of the T-SQL query writing. Please note that the query which is automatically changed is not in New Query Editor but opened from SSMS using following way. Database >> Views >> Right Click >> New View (see the image below) Answer: The answer to the above question can be very long but I will keep it simple and to the point. There are three things to discuss in above script 1) Reason for Error 2) Reason for Auto generates TOP (100) PERCENT and 3) Potential solutions to the above error. Let us quickly see them in detail. 1) Reason for Error The reason for error is already given in the error. ORDER BY is invalid in the views and a few other objects. One has to use TOP or other keywords along with it. The way semantics of the query works where optimizer only follows(honors) the ORDER BY in the same scope or the same SELECT/UPDATE/DELETE statement. There is a possibility that one can order after the scope of the view again the efforts spend to order view will be wasted. The final resultset of the query always follows the final ORDER BY or outer query’s order and due to the same reason optimizer follows the final order of the query and not of the views (as view will be used in another query for further processing e.g. in SELECT statement). Due to same reason ORDER BY is now allowed in the view. For further accuracy and clear guidance I suggest you read this blog post by Query Optimizer Team. They have explained it very clear manner the same subject. 2) Reason for Auto Generated TOP (100) PERCENT One of the most popular workaround to above error is to use TOP (100) PERCENT in the view. Now TOP (100) PERCENT allows user to use ORDER BY in the query and allows user to overcome above error which we discussed. This gives the impression to the user that they have resolved the error and successfully able to use ORDER BY in the View. Well, this is incorrect as well. The way this works is when TOP (100) PERCENT is used the result is not guaranteed as well it is ignored in our the query where the view is used. Here is the blog post on this subject: Interesting Observation – TOP 100 PERCENT and ORDER BY. Now when you create a new view in the SSMS and build a query with ORDER BY to avoid the error automatically it adds the TOP 100 PERCENT. Here is the connect item for the same issue. I am sure there will be more connect items as well but I could not find them. 3) Potential Solutions If you are reading this post from the beginning in that case, it is clear by now that ORDER BY should not be used in the View as it does not serve any purpose unless there is a specific need of it. If you are going to use TOP 100 PERCENT with ORDER BY there is absolutely no need of using ORDER BY rather avoid using it all together. Here is another blog post of mine which describes the same subject ORDER BY Does Not Work – Limitation of the Views Part 1. It is valid to use ORDER BY in a view if there is a clear business need of using TOP with any other percentage lower than 100 (for example TOP 10 PERCENT or TOP 50 PERCENT etc). In most of the cases ORDER BY is not needed in the view and it should be used in the most outer query for present result in desired order. User can remove TOP 100 PERCENT and ORDER BY from the view before using the view in any query or procedure. In the most outer query there should be ORDER BY as per the business need. I think this sums up the concept in a few words. This is a very long topic and not easy to illustrate in one single blog post. I welcome your comments and suggestions.

  • DBCC MEMUSAGE in 2005/8 ?

    - by steveh99999
    I used to like using undocumented command DBCC MEMUSAGE in SQL 2000 to see which tables were using space in SQL data cache. In SQL 2005, this command is not longer present. Instead a DMV – sys.dm_os_buffer_descriptors – can be used to display data cache contents,  but this doesn’t quite give you the same output as DBCC MEMUSAGE. I’m also aware that you can use Quest’s spotlight tool to view a summary of data cache contents. Using  this post by Umachandar Jayachandran  of Microsoft, I was able to create the following equivalent for SQL 2005/8. I’ve wrapped Umachandar’s original query in a CTE to produce summary information :- ;WITH memusage_CTE AS (SELECT bd.database_id, bd.file_id, bd.page_id, bd.page_type , COALESCE(p1.object_id, p2.object_id) AS object_id , COALESCE(p1.index_id, p2.index_id) AS index_id , bd.row_count, bd.free_space_in_bytes, CONVERT(TINYINT,bd.is_modified) AS 'DirtyPage' FROM sys.dm_os_buffer_descriptors AS bd JOIN sys.allocation_units AS au ON au.allocation_unit_id = bd.allocation_unit_id OUTER APPLY ( SELECT TOP(1) p.object_id, p.index_id FROM sys.partitions AS p WHERE p.hobt_id = au.container_id AND au.type IN (1, 3) ) AS p1 OUTER APPLY ( SELECT TOP(1) p.object_id, p.index_id FROM sys.partitions AS p WHERE p.partition_id = au.container_id AND au.type = 2 ) AS p2 WHERE  bd.database_id = DB_ID() AND bd.page_type IN ('DATA_PAGE', 'INDEX_PAGE') ) SELECT TOP 20 DB_NAME(database_id) AS 'Database',OBJECT_NAME(object_id,database_id) AS 'Table Name', index_id,COUNT(*) AS 'Pages in Cache', SUM(dirtyPage) AS 'Dirty Pages' FROM memusage_CTE GROUP BY database_id, object_id, index_id ORDER BY COUNT(*) DESC I’m not 100% happy with the results of the above query however… I’ve noticed that on a busy BizTalk messageBox database  it will return information on pages that contain GHOST rows – . ie where data has already been deleted but has yet to be cleaned-up by a background process – I’m need to investigate further why cache on this server apparently contains so much GHOST data… For more information on the background ghost cleanup process, see this article by Paul Randall. However, I think the results of this query should still be of interest to a DBA. I have another post to come shortly regarding an example I encountered where this information proved useful to me… I notice in SQL 2008, sys.dm_os_buffer_descriptors gained an extra column – numa_mode – I’m interested to see how this is populated and how useful this column can be on a NUMA-enabled system. I’m assuming in theory you could use this column to help analyse how your tables are spread across Numa-enabled data-cache ?
