• JQuery - Collection Iteration

  - by user70192

  Hello, I am new to JQuery. I have a select html element. I am trying to understand how to iterate through the options in the select element. I know how to do it with traditional javascript as shown here: for (i=0; i<mySelect.options.length; i++) alert(mySelect.options[i].value); However, I'm trying to learn about JQuery more. Can someone show me the best way to iterate through a collection using JQuery? Thank you

• Stored procedure and trigger

  - by noober

  Hello all, I had a task -- to create update trigger, that works on real table data change (not just update with the same values). For that purpose I had created copy table then began to compare updated rows with the old copied ones. When trigger completes, it's neccessary to actualize the copy: UPDATE CopyTable SET id = s.id, -- many, many fields FROM MainTable s WHERE s.id IN (SELECT [id] FROM INSERTED) AND CopyTable.id = s.id; I don't like to have this ugly code in trigger anymore, so I has extracted it to a stored procedure: CREATE PROCEDURE UpdateCopy AS BEGIN UPDATE CopyTable SET id = s.id, -- many, many fields FROM MainTable s WHERE s.id IN (SELECT [id] FROM INSERTED) AND CopyTable.id = s.id; END The result is -- Invalid object name 'INSERTED'. How can I workaround this? Regards,

• Query to get row from one table, else random row from another

  - by Jimmy

  tblUserProfile - I have a table which holds all the Profile Info (too many fields) tblMonthlyProfiles - Another table which has just the ProfileID in it (the idea is that this table holds 2 profileids which sometimes become monthly profiles (on selection)) Now when I need to show monthly profiles, I simply do a select from this tblMonthlyProfiles and Join with tblUserProfile to get all valid info. If there are no rows in tblMonthlyProfile, then monthly profile section is not displayed. Now the requirement is to ALWAYS show Monthly Profiles. If there are no rows in monthlyProfiles, it should pick up 2 random profiles from tblUserProfile. If there is only one row in monthlyProfiles, it should pick up only one random row from tblUserProfile. What is the best way to do all this in one single query ? I thought something like this select top 2 * from tblUserProfile P LEFT OUTER JOIN tblMonthlyProfiles M on M.profileid = P.profileid ORder by NEWID() But this always gives me 2 random rows from tblProfile. How can I solve this ?

• javascript pop-up menu help

  - by baiano

  I am working on a project similar to a table where the user will be able to add rows. Right now there is just one row type available but I would like to give the user the ability to select from a list without changing the layout of the page. So, I put together a menu that appears on mouseover of the 'add row' link and disappears on mouseout (with a slight delay and fade in/out) using mootools event listeners. It looks like: I am now trying to figure out an easy way to make it so that the list stays available when the user's mouse leaves the 'add a row' link to go to select an item from the list. I looked through various mootools add-ons and tutorial but didn't find anything all that helpful. Does anyone know of a good tutorial guide me through this or can otherwise point me in the right direction here?

• CheckBox header renderer with HierarchicalCollectionView

  - by fumeng

  Hi - I've gotten a checkbox header renderer to work well with flat DPs, but a hierarchical collection view is another story. On click, I want it to select all checkboxes in a given column. Here is my code: var dp:HierarchicalCollectionView = _dataGrid.dataProvider as HierarchicalCollectionView; var testDp:GroupingCollection = dp.source as GroupingCollection; var rawDp:ArrayCollection = testDp.source as ArrayCollection; for(var i:int=0 ; i < rawDp.length ; i++){ rawDp[i][_dataField] = cb.selected; } It selects all checkboxes on the 2nd level of data, but doesn't select the top level of data. What am I missing here? I can't seem to find it. Any tips are greatly appreciated. Thank you.

• Is it safe to run multiple XNA ContentManager instances on multiple threads?

  - by Boinst

  My XNA project currently uses one ContentManager instance, and one dedicated background thread for loading all content. I wonder, would it be safe to have multiple ContentManager instances, each in it's own dedicated thread, loading different content at the same time? I'm prompted to ask this question because this article makes the following statement: If there are two textures created at the same time on different threads, they will clobber the other and you will end up with some garbage in the textures. I think that what the author is saying here, is that if I access one ContentManager simultaneously on two threads, I'll get garbage. But what if I have separate ContentManager instances for each thread? If no-one knows the answer already from experience, I'll go ahead and try it and see what happens.

• Radio Buttons not highlighting as though they are selected

  - by Ryan

  I'm working on an android activity with a RadioGroup containing 10 RadioButtons. For some reason or another sometimes, only sometimes, when you select a RadioButton in the RadioGroup it doesn't highlight as if it's selected but through some tests I've determined that it really IS selected even though it isn't highlighted. Another odd thing that occurs is that when you select any other RadioButton in the RadioGroup and then try selecting your original Radio Button (the one that wouldn't highlight as though it were selected) it does highlight and functions as normal. Any idea why this is happening or how to fix it? Thanks!

• SQL Server - Searching string with international characters using LIKE clause

  - by Nikhil

  Hi, I have a field 'Description' which can have product descriptions with any unicode characters. If I search for a description which contains an international character, with a LIKE condition (word searched with does not have the international character) I get the following results: Ex: GEWÜRZTRAMINER is one of the descriptions. When I do: Select * from table where Description LIKE '%GEWURZTRAMINER%', it retrieves the entry. When I do: Select * from table where Description LIKE '%GEWURZ%', the entry is not retrieved. (Note: the search condition does not include the Ü but has a U) Is there a way around this so that I can retrieve with '%GEWURZ%' as well? SQl Server 2008

• variable declaration in javascript [migrated]

  - by ShaggyInjun

  I have been doing something like this for a while and I have never seen any errors. But, unfortunately, I have never been able to explain why this works. The first line creates a variable which points to a function. The second line just adds func2 to func1 separated by a dot and defines a function. If I add a var in front of func1.func2 then I see a compilation error. func1.func2 = function(){}; Error SyntaxError: missing ; before statement var func1.func2 = function(){}; What type was func1 on first line 1 and what did it become on line 2. var func1 = function(){}; func1.func2 = function(){}; Thanks Venkat

• XSLT 2.0 Header Leaks into Transformed XML

  - by user1303797

  First, a thank you in advance. Second, this is my first post so apologies for any errors or wrongdoings. I am a noob w/ xml and xslt, and can't seem to figure this out. When I transform some xml using xslt 2.0, some of the headers from the xslt leaks into the new xml. It doesn't seem to do it in xslt 1.0 (granted the xslt is a little different). Here is the xml: <?xml version="1.0" encoding="ISO-8859-1" ?> <xml_content> <feed_name>feed</feed_name> <feed_info> <entry_1> <id>1</id> <pub_date>1320814800</pub_date> </entry_1> </feed_info> </xml_content> Here is the xslt: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/TR/xhtml1/strict"> <xsl:output method="xml" indent="yes" /> <xsl:template match="xml_content"> <Records> <xsl:for-each select="feed_info/entry_1"> <Record> <ID><xsl:value-of select="id" /></ID> <PublicationDate><xsl:value-of select='xs:dateTime("1970-01-01T00:00:00") + xs:integer(pub_date) * xs:dayTimeDuration("PT1S")'/></PublicationDate> </Record> </xsl:for-each> </Records> </xsl:template> </xsl:stylesheet> Here is the new xml. Look specifically at the first "Records" element. <?xml version="1.0" encoding="UTF-8"?> <Records xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://www.w3.org/TR/xhtml1/strict"> <Record> <ID>1</ID> <PublicationDate>2011-11-09T05:00:00</PublicationDate> </Record> </Records>

• Assign the results of a stored procedure into a variable in another stored procedure

  - by RHPT

  The title of this question is a bit misleading, but I couldn't summarize this very well. I have two stored procedures. The first stored procedure (s_proc1) calls a second stored procedure (s_proc2). I want to assign the value returned from s_proc2 to a variable in s_proc1. Currently, I'm calling s_proc2 (inside s_proc1) in this manner: EXEC s_proc2 @SiteID, @count = @PagingCount OUTPUT s_proc2 contains a dynamic query statement (for reasons I will not outline here). CREATE dbo.s_proc2 ( @siteID int, @count int OUTPUT ) AS DECLARE @sSQL nvarchar(100) DECLARE @xCount int SELECT @sSQL = 'SELECT COUNT(ID) FROM Authors' EXEC sp_ExecuteSQL @sSQL, N'@xCount int output', @xCount output SET @count = @xCount RETURN @count Will this result in @PagingCount having the value of @count? I ask because the result I am getting from s_proc1 is wonky. In fact, what I do get is two results. The first being @count, then the result of s_proc1 (which is incorrect). So, it makes me wonder if @PagingCount isn't being set properly. Thank you.

• Adding more OR searches with CONTAINS Brings Query to Crawl

  - by scolja

  I have a simple query that relies on two full-text indexed tables, but it runs extremely slow when I have the CONTAINS combined with any additional OR search. As seen in the execution plan, the two full text searches crush the performance. If I query with just 1 of the CONTAINS, or neither, the query is sub-second, but the moment you add OR into the mix the query becomes ill-fated. The two tables are nothing special, they're not overly wide (42 cols in one, 21 in the other; maybe 10 cols are FT indexed in each) or even contain very many records (36k recs in the biggest of the two). I was able to solve the performance by splitting the two CONTAINS searches into their own SELECT queries and then UNION the three together. Is this UNION workaround my only hope? Thanks. SELECT a.CollectionID FROM collections a INNER JOIN determinations b ON a.CollectionID = b.CollectionID WHERE a.CollrTeam_Text LIKE '%fa%' OR CONTAINS(a.*, '"*fa*"') OR CONTAINS(b.*, '"*fa*"') Execution Plan (guess I need more reputation before I can post the image):

• Casting a Calculated Column in a MySQL view.

  - by Chris Brent

  I have a view that contains a calculated column. Is there are a way to cast it as a CHAR or VARCHAR rather than a VARBINARY ? Obviously, I have tried using CAST(... as CHAR) but it gives an error. Here is a simple replicable example. CREATE VIEW view_example AS SELECT concat_ws('_', lpad(9, 3,'0'), lpad(1,3,'0'), date_format(now(),'%Y%m%d%H%i%S')) AS calculated_field_id; This is how my view is created: describe view_example; +---------------------+---------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +---------------------+---------------+------+-----+---------+-------+ | calculated_field_id | varbinary(27) | YES | | NULL | | +---------------------+---------------+------+-----+---------+-------+ select version(); +-----------------------+ | version() | +-----------------------+ | 5.0.51a-community-log | +-----------------------+

• How to enable an AdventureWorks database in a web application?

  - by salvationishere

  I am developing a C#/SQL ASP.NET web application in VS 2008. I want the users to be able to select an Adventureworks table and then an input file. The user is then able to map columns from the file with the selected table. This app works fine now in VS. But when I Browse in IIS, it doesn't show any of the tables. I think this is because currently Adventureworks connection string is integrated security (Windows authentication). If I want users to be able to select a table, do I have to change connection to SQL Server authentication? And if so, is the only way to do this to reinstall SQL Server? Or can I just reinstall Adventureworks? And if I reinstall SQL Server, do I need to reinstall VS also for this to work? This could be painful...

• Nhibernate and not-exists query

  - by Dan

  I'm trying to construct a query in NHibernate to return a list of customers with no orders matching a specific criteria. My Customer object contains a set of Orders: <set name="Orders"> <key column="CustomerID" /> <one-to-many class="Order" /> </set> How do I contruct a query using NHibernate's ICriteria API to get a list of all customers who have no orders? Using native SQL, I am able to represent the query like this: select * from tblCustomers c where not exists (select 1 from tblOrders o where c.ID = o.CustomerID) I have been unable to figure out how to do this using aliases and DetatchedCriteria objects. Any guidance would be appreciated! Thanks!

• SQL Selecting from one table OR another then joining the two

  - by Cyprus106

  So this is interesting, and apparently beyond my SQL skillset. I need to select a particular record where an ID="0003" (or whatever) from either table1 or table2 if table1 doesn't have that record. Then I need to join table1 and table2 on a mutual field they both have (field name is Product_ID) I was playing with all sorts of variations of the following, (no, it doesn't work) but after 2 days of groping through the internet and a big SQL book I still can't figure anything out. SELECT ProductStock.Product_ID AS PSID, Products.ID AS PID, ProductStock.*, Products.* FROM ProductStock, Products LEFT JOIN (Products AS Pr) ON Pr.ID=ProductStock.Product_ID WHERE (ProductStock.ID="6003" OR Products.ID="6003")
