  • Group functions of outer query inside inner query

    - by superdario
    Hello, I'm using Oracle. I'm trying to compose something like this: SELECT trans_type, (SELECT parameter_value FROM transaction_details WHERE id = MAX(t.trans_id)) FROM (SELECT trans_id, trans_type FROM transactions) t GROUP BY trans_type So, I am trying to use a result of grouping inside an inner query. But I am getting the error that I cannot use a group function inside the inner query: ORA-00934: group function is not allowed here Can you offer an alternative other than resorting to another outer query?

  • Streamlining my javascript with a function

    - by liz
    i have a series of select lists, that i am using to populate text boxes with ids. so you click a select option and another text box is filled with its id. with just one select/id pair this works fine, but i have multiples, and the only thing that changes is the id of the select and input.. in fact just the ending changes, the inputs all start with featredproductid and the select ids all start with recipesproduct and then both end with the category. i know that listing this over and over for each category is not the way to do it. i think i need to make an array of the categories var cats = ['olive oil', "grains", "pasta"] and then use a forEach function? maybe? here is the clunky code window.addEvent('domready', function() { $('recipesproductoliveoil').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidoliveoil").setProperties({ value: pidselected}); ; }); $('recipesproductgrains').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidgrains").setProperties({ value: pidselected}); ; }); $('recipesproductpasta').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidpasta").setProperties({ value: pidselected}); ; }); $('recipesproductpantry').addEvent('change', function(e){ pidselected = this.options[this.selectedIndex].getProperty('value') ; $("featuredproductidpantry").setProperties({ value: pidselected}); ; }); }); keep in mind this is mootools 1.1 (no i cant update it sorry). i am sure this is kind of basic, something i seem to have wrapping my brain around. but i am quite sure doing it as above is not really good...

  • Store variables during loop and use in it another template

    - by krisvandenbergh
    Is there a way to store a variable/param during a for-each loop in a sort of array, and use it in another template, namely <xsl:template match="Foundation.Core.Classifier.feature">. All the classname values that appear during the for-each should be stored. How would you implement that in XSLT? Here's my current code. <xsl:for-each select="Foundation.Core.Class"> <xsl:for-each select="Foundation.Core.ModelElement.name"> <xsl:param name="classname"> <xsl:value-of select="Foundation.Core.ModelElement.name"/> </xsl:param> </xsl:for-each> <xsl:apply-templates select="Foundation.Core.Classifier.feature" /> </xsl:for-each> Here's the template in which the classname parameters should be used. <xsl:template match="Foundation.Core.Classifier.feature"> <xsl:for-each select="Foundation.Core.Attribute"> <owl:DatatypeProperty rdf:ID="{Foundation.Core.ModelElement.name}"> <rdfs:domain rdf:resource="$classname" /> </owl:DatatypeProperty> </xsl:for-each> </xsl:template> The input file can be found at http://krisvandenbergh.be/uml_pricing.xml

  • How to sort list items for Date field value (Apex, Salesforce)

    - by Channa
    With Salesforce's Apex, is there any way to sort list items, for Date field value. Please refer the TODO section of the following code, thanks. /** * Select list of jobOccurrences belongs to particular list of jobs */ private List<Job_Occurrence__c> getJobsByJobCode(List<Job__c> jobList) { // Select relevant Job Occurrence objects List<Job_Occurrence__c> jobOccuList = new List<Job_Occurrence__c>(); for (Job__c job : jobList) { Job_Occurrence__c jobOccurrence = [SELECT Id, Job__c, Schedule_Start_Date__c FROM Job_Occurrence__c WHERE Job__c =: job.Id]; if((jobOccurrence != null) && (jobOccurrence.Id != null)) { jobOccuList.add(jobOccurrence); } } if((jobOccuList != null) && (jobOccuList.size() > 0)) { // TODO // How I sort the 'jobOccuList' with Date field 'Schedule_Start_Date__c', // for select the items according to sequence of latest jobOccurrence return jobOccuList; } else { throw new RecordNotFoundException ('Could not found any jobOccurrence for given list of jobs'); } }

  • query optimization

    - by Gaurav
    I have a query of the form SELECT uid1,uid2 FROM friend WHERE uid1 IN (SELECT uid2 FROM friend WHERE uid1='.$user_id.') and uid2 IN (SELECT uid2 FROM friend WHERE uid1='.$user_id.') The problem now is that the nested query SELECT uid2 FROM friend WHERE uid1='.$user_id.' returns a very large number of ids(approx. 5000). The table structure of the friend table is uid1(int), uid2(int). This table is used to determine whether two users are linked together as friends. Any workaround? Can I write the query in a different way? Or is there some other way to solve this issue. I'm sure I am not the first person to face such a problem. Any help would be greatly appreciated.

  • What can be used instead of Datatable in LINQ

    - by Kabi
    I have a SQL query that returns a Datatable: var routesTable = _dbhelper.Select("SELECT [RouteId],[UserId],[SourceName],[CreationTime] FROM [Routes] WHERE UserId=@UserId AND RouteId=@RouteId", inputParams); and then we can work with Datatable object of routesTable if (routesTable.Rows.Count == 1) { result = new Route(routeId) { Name = (string)routesTable.Rows[0]["SourceName"], Time = routesTable.Rows[0]["CreationTime"] is DBNull ? new DateTime() : Convert.ToDateTime(routesTable.Rows[0]["CreationTime"]) }; result.TrackPoints = GetTrackPointsForRoute(routeId); } I want to change this code to linq but I don't know how can I simulate Datatable in LINQ ,I wrote this part: Route result = null; aspnetdbDataContext aspdb = new aspnetdbDataContext(); var Result = from r in aspdb.RouteLinqs where r.UserId == userId && r.RouteId==routeId select r; .... but I don't know how can I change this part: if (routesTable.Rows.Count == 1) { result = new Route(routeId) { Name = (string)routesTable.Rows[0]["SourceName"], Time = routesTable.Rows[0]["CreationTime"] is DBNull ? new DateTime() : Convert.ToDateTime(routesTable.Rows[0]["CreationTime"]) }; would you please tell me how can I do this? EDIT here you can see the whole block of code in original public Route GetById(int routeId, Guid userId) { Route result = null; var inputParams = new Dictionary<string, object> { {"UserId", userId}, {"RouteId", routeId} }; var routesTable = _dbhelper.Select("SELECT [RouteId],[UserId],[SourceName],[CreationTime] FROM [Routes] WHERE UserId=@UserId AND RouteId=@RouteId", inputParams); if (routesTable.Rows.Count == 1) { result = new Route(routeId) { Name = (string)routesTable.Rows[0]["SourceName"], Time = routesTable.Rows[0]["CreationTime"] is DBNull ? new DateTime() : Convert.ToDateTime(routesTable.Rows[0]["CreationTime"]) }; result.TrackPoints = GetTrackPointsForRoute(routeId); } return result; }

  • Hos to group the complex list objects by using Linq

    - by Daoming Yang
    I want to select and group the products, and rank them by the number of times they occur. For example, I have an OrderList each of order object has a OrderProductVariantList(OrderLineList), and each of OrderProductVariant object has ProductVariant, and then the ProductVariant object will have a Product object which contains product information. A friend helped me with the following code. It could be compiled, but it did not return any value/result. I used the watch window for the query and it gave me "The name 'query' does not exist in the current context". Can anyone help me? Many thanks. var query = orderList.SelectMany( o => o.OrderLineList ) // results in IEnumerable<OrderProductVariant> .Select( opv => opv.ProductVariant ) .Select( pv => p.Product ) .GroupBy( p => p ) .Select( g => new { Product = g.Key, Count = g.Count() });

  • Sub-total and total columns

  • How can you tell MYSQL to TRIM the X number of characters, beginning from the Back?

    - by Tim
    How do I write the following in MYSQL? SELECT SUBSTRING(value - (1 TRAILING CHARACTER)) FROM table; Basically substring(value, 2) trims the first letters. But I need to trim the last letters. I can't use substring(value, -4, 3) because I don't know the length of the value. Here's another example: SELECT * FROM table WHERE SUBSTRING(value - (4 TRAILING CHARACTER)) in (SELECT SUBSTRING(value - (1 TRAILING CHARACTER)) FROM table);

  • Basic question about request queues in IIS / ASP.Net

    - by larryq
    I have an ASP.Net application running under IIS 6. A simple page has two radio buttons and a submit button. If I select radio button "A" and submit the page, a lengthy PDF file is generated, which takes about a minute to build. If I select radio button "B", a small PDF is generated. (In both cases the PDF is written out to the Response object and it opens in my browser.) If I select radio button "A" and submit, then hit the red X in my browser to stop the current request, then select radio button "B" and resubmit, the page still takes a long time to process my request. No doubt my first request is still being processed on the server, but I was wondering how IIS and/or ASP.Net are queuing my requests so that fair server use is guaranteed among all users. Am I roughly correct in assuming something like this happens, and if so, how is it done?

  • In VisualStudio 2008, emacs mode - how can you enable "overwrite"?

    - by Abby Fichtner
    Using VisualStudio 2008, have emacs keyboard mapping scheme enabled. If I select text and try to paste over it, it INSERTS the new text, rather than replacing it. Also, if I select text and hit DELETE it deletes the first character AFTER the selected text (just as if I didn't have any text selected). Does anyone know how to fix this so that I get the standard windows behavior. That is: If I select text and try to paste over it, it replaces the selected text with what I pasted in. If I select text and hit the DELETE key, it actually deletes the text I have selected Thanks! Abby

  • How do I combine these similar linq queries into one?

    - by MikeD
    This is probably a basic LINQ question. I have need to select one object and if it is null select another. I'm using linq to objects in the following way, that I know can be done quicker, better, cleaner... public Attrib DetermineAttribution(Data data) { var one = from c in data.actions where c.actionType == Action.ActionTypeOne select new Attrib { id = c.id, name = c.name }; if( one.Count() > 0) return one.First(); var two = from c in data.actions where c.actionType == Action.ActionTypeTwo select new Attrib { id = c.id, name = c.name }; if (two.Count() > 0 ) return two.First(); } The two linq operations differ only on the where clause and I know there is a way to combine them. Any thoughts would be appreciated.

  • Shortening jQuery Code by Replacing Variable

    - by Jerry
    I have a form with a bunch of dropdown options that I'm dressing up by allowing the option to be selected by clicking links and (in the future, images) instead of using the actual dropdown. There are a lot of dropdowns and most all will repeat the same basic idea, and some will literally repeat just with different variables. Here's the HTML for one of those. <tr class="box1"> <td> <select id="cimy_uef_7"> <option value="Boy">Boy</option> <option value="Girl">Girl</option> </select> </td> </tr> Then the corresponding fancier links to click that will select the corresponding option in the dropdown. <div id="genderBox1"> <div class="gender"><a class="boy" href="">Boy</a></div> <div class="gender"><a class="girl" href="">Girl</a></div> </div> So, when you click the link "Boy" it will select the corresponding dropdown value "Boy" There are going to be multiple Box#, so I can just repeat the jQuery each time with the new variables, but there's surely a shorter way. Here's the jQuery that makes it work. //Box1 Gender var Gender1 = $('select#cimy_uef_7'); var Boy1 = $("#genderBox1 .gender a.boy"); var Girl1 = $("#genderBox1 .gender a.girl"); //On Page Load - Check Gender Box 1 Selection and addClass to corresponding div a if ( $(Gender1).val() == "Boy" ) { $(Boy1).addClass("selected"); } else { $(Boy1).removeClass("selected"); } if ( $(Gender1).val() == "Girl" ) { $(Girl1).addClass("selected"); } else { $(Girl1).removeClass("selected"); } //On Click - Change Gender Box 1 select based on image click $(Boy1).click(function(event) { event.preventDefault(); $(this).addClass("selected"); $(Gender1).val("Boy"); $(Girl1).removeClass("selected"); }); $(Girl1).click(function(event) { event.preventDefault(); $(this).addClass("selected"); $(Gender1).val("Girl"); $(Boy1).removeClass("selected"); }); My thought for shortening it was to just have a list of variables for each box and cycle through the numbers- 1,2,3,4 and have the jQuery grab the same # for each variable, but I can't figure out a way to do it. Let me know if there's anything else I can provide to make the question better. This is my best idea for shortening this code, as I'm still very much a beginner at jQuery, but I'm positive there are much better ideas out there, so feel free to recommend a better path if you see it :)

  • Disable TSQL script check?

    - by grady
    Hi, lets say I have a script like that: if(some condition) begin select somecolumn from sometable end Lets say, that "somecolumn" does not exist and the condition is not true, which means the select is NOT executed. Even though the select would not be executed, the script is not valid, Management Studio complains about the missing column "somecolumn". Question: Can I somehow disable this sort of check so that the script is executed and since the if is not true, it will never notice that the column is missing? Thanks :-)

  • Silverlight 3 data-binding child property doesn't update

    - by sonofpirate
    I have a Silverlight control that has my root ViewModel object as it's data source. The ViewModel exposes a list of Cards as well as a SelectedCard property which is bound to a drop-down list at the top of the view. I then have a form of sorts at the bottom that displays the properties of the SelectedCard. My XAML appears as (reduced for simplicity): <StackPanel Orientation="Vertical"> <ComboBox DisplayMemberPath="Name" ItemsSource="{Binding Path=Cards}" SelectedItem="{Binding Path=SelectedCard, Mode=TwoWay}" /> <TextBlock Text="{Binding Path=SelectedCard.Name}" /> <ListBox DisplayMemberPath="Name" ItemsSource="{Binding Path=SelectedCard.PendingTransactions}" /> </StackPanel> I would expect the TextBlock and ListBox to update whenever I select a new item in the ComboBox, but this is not the case. I'm sure it has to do with the fact that the TextBlock and ListBox are actually bound to properties of the SelectedCard so it is listening for property change notifications for the properties on that object. But, I would have thought that data-binding would be smart enough to recognize that the parent object in the binding expression had changed and update the entire binding. It bears noting that the PendingTransactions property (bound to the ListBox) is lazy-loaded. So, the first time I select an item in the ComboBox, I do make the async call and load the list and the UI updates to display the information corresponding to the selected item. However, when I reselect an item, the UI doesn't change! For example, if my original list contains three cards, I select the first card by default. Data-binding does attempt to access the PendingTransactions property on that Card object and updates the ListBox correctly. If I select the second card in the list, the same thing happens and I get the list of PendingTransactions for that card displayed. But, if I select the first card again, nothing changes in my UI! Setting a breakpoint, I am able to confirm that the SelectedCard property is being updated correctly. How can I make this work???

  • Hiding <option>s in IE

    - by Mark
    I wrote this nifty function to filter select boxes when their value is changed... $.fn.cascade = function() { var opts = this.children('option'); var rel = this.attr('rel'); $('[name='+rel+']').change(function() { var val = $(this).val(); var disp = opts.filter('[rel='+val+']'); opts.filter(':visible').hide(); disp.show(); if(!disp.filter(':selected').length) { disp.filter(':first').attr('selected','selected'); } }).trigger('change'); return this; } It looks at the rel property, and if the element indicated by rel changes, then it filters the list to only show the options that have that value... for example, it works on HTML that looks like this: <select id="id-pickup_address-country" name="pickup_address-country"> <option selected="selected" value="CA">Canada </option> <option value="US">United States </option> </select> <select id="id-pickup_address-province" rel="pickup_address-country" name="pickup_address-province"> <option rel="CA" value="AB">Alberta </option> <option selected="selected" rel="CA" value="BC">British Columbia </option> <option rel="CA" value="MB">Manitoba </option>... </select> However, I just discovered it doesn't work properly in IE (of course!) which doesn't seem to allow you to hide options. How can I work around this?

  • SQL Group By equivalent

    - by MikeB
    Pretend I have a cupcake_rating table: id | cupcake | delicious_rating -------------------------------------------- 1 | Strawberry | Super Delicious 2 | Strawberry | Mouth Heaven 3 | Blueberry | Godly 4 | Blueberry | Super Delicious I want to find all the cupcakes that have a 'Super Delicious' AND 'Mouth Heaven' rating. I feel like this is easily achievable using a group by clause and maybe a having. I was thinking: select distinct(cupcake) from cupcake_rating group by cupcake having delicious_rating in ('Super Delicious', 'Mouth Heaven') I know I can't have two separate AND statements. I was able to achieve my goal using: select distinct(cupcake) from cupcake_rating where cupcake in ( select cupcake from cupcake_rating where delicious_rating = 'Super Delicious' ) and cupcake in ( select cupcake from cupcake_rating where delicious_rating = 'Mouth Heaven' ) This will not be satisfactory because once I add a third type of rating I am looking for, the query will take hours (there are a lot of cupcake ratings).

  • SQL: Order randomly when inserting objects to a table

(btw SQL 2005) So I paste the UDF below and what the code does is: selects objects for a specific city and add a level to those (from table Europe) union that selection with a selection from the same table for objects that are from the same country and add a level to those From the union, selection is made to get top 6 objects, order by level, so the objects from the same city will be first, and if there aren't any available, then objects from the same country will be returned from the selection. And my problem is, that I want to make a random selection to get random objects from table Europe, but because I insert the result of my selection into a table, I can't use order by newid() or rand() function because they are time-dependent, so I get the following errors: Invalid use of side-effecting or time-dependent operator in 'newid' within a function. Invalid use of side-effecting or time-dependent operator in 'rand' within a function. UDF: ALTER FUNCTION [dbo].[Objects] (@id uniqueidentifier) RETURNS @objects TABLE ( ObjectId uniqueidentifier NOT NULL, InternalId uniqueidentifier NOT NULL ) AS BEGIN declare @city varchar(50) declare @country int select @city = city, @country = country from Europe where internalId = @id insert @objects select @id, internalId from ( select distinct top 6 [level], internalId from ( select top 6 1 as [level], internalId from Europe N4 where N4.city = @city and N4.internalId != @id union select top 6 2 as [level], internalId from Europe N5 where N5.countryId = @country and N5.internalId != @id ) as selection_1 order by [level] ) as selection_2 return END If you have fresh ideas, please share them with me. (Just please, don't suggest to order by newid() or to add a column rand() with seed DateTime (by ms or sthg), because that won't work.)

  • Subquery works in 9i but not in 11g

    - by Zsuetam
    Statement below is working on Oracle 9i but not on Oracle 11g SELECT * FROM ( SELECT 0 scrnfail_rate, '9' zz, 7 hh FROM DUAL UNION ALL SELECT 0 scrnfail_rate, '9' zz, 7 hh FROM DUAL ) WHERE zz IS NOT NULL AND TO_CHAR (hh) NOT IN ( SELECT DECODE ( scrnfail_rate, 0, -1, ROUND (LEVEL * 1 / (scrnfail_rate / 100)) - ROUND (1 / (2 * (scrnfail_rate / 100))) ) AS nno FROM DUAL WHERE NVL (scrnfail_rate, 0) > 0 CONNECT BY LEVEL <= ROUND(9 * scrnfail_rate / 100) ) It looks like Oracle 11g is ignoring where decode or even where clause in the subquery. This query should return two rows as it does on Oracle 9i, but results ORA-01476: divisor is equal to zero on Oracle 11g EE 11.2.0.1.0 - 64bit. Can anyone help? Thanks!

  • How do I combine grouped nodes?

    - by LOlliffe
    Using the XSL: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0"> <xsl:output method="xml"/> <xsl:template match="/"> <records> <record> <!-- Group record by bigID, for further processing --> <xsl:for-each-group select="records/record" group-by="bigID"> <xsl:sort select="bigID"/> <xsl:for-each select="current-group()"> <!-- Create new combined record --> <bigID> <!-- <xsl:value-of select="."/> --> <xsl:for-each select="."> <xsl:value-of select="bigID"/> </xsl:for-each> </bigID> <text> <xsl:value-of select="text"/> </text> </xsl:for-each> </xsl:for-each-group> </record> </records> </xsl:template> I'm trying to change: <?xml version="1.0" encoding="UTF-8"?> <records> <record> <bigID>123</bigID> <text>Contains text for 123</text> <bigID>456</bigID> <text>Some 456 text</text> <bigID>123</bigID> <text>More 123 text</text> <bigID>123</bigID> <text>Yet more 123 text</text> </record> into: <?xml version="1.0" encoding="UTF-8"?> <records> <record> <bigID>123</bigID> <text>Contains text for 123</text> <text>More 123 text</text> <text>Yet more 123 text</text> </bigID> <bigID>456 <text>Some 456 text</text> </bigID> </record> Right now, I'm just listing the grouped <bigIDs, individually. I'm missing the step after grouping, where I combine the grouped <bigID nodes. My suspicion is that I need to use the "key" function somehow, but I'm not sure. Thanks for any help.

  • T-SQL error object exists when separated in if/else blocks

    - by Jeff O
    I get the error: Msg 2714, Level 16, State 1, Line 16 There is already an object named '#mytemptable' in the database. There are ways around it, but wonder why this happens. Seems like SQL Server is verifying both blocks of the if/else statement? declare @choice int select @choice = 1 if @choice = 1 begin select 'MyValue = 1' AS Pick into #my_temp_table end else begin select 'MyValue <> 1' AS Pick into #my_temp_table end select * from #temptable drop table #temptable If the tables have different names, it works. Or if I create the temp table and use Insert Into... statements that works as well.

  • IE6 HTML control wrapping

    - by astonius
    Is there any way to prevent wrapping across controls in IE6? For example, I have a label and a single select box. The select box width is dynamic (depending on the content). I want the label to always be to the left of the select box. Right now the problem I am having is the select box drops below the label. I have tried using the <nobr> tag as well as CSS word-wrap rules, but because this isn't text the wrapping rules do not apply. The only way I have found for sure to make it work is to place them in a two-column table, but I do not like this solution. Is there any other way?
