  • NHibernate Native SQL multiple joins

    - by Chris
    Hi all, I"m having some problems with Nhibernate and native sql. I've got an entity with alot of collections and I am doing an SQL Fulltext search on it. So when returning 100 or so entities, I dont want all collections be lazy loaded. For this I changed my SQL query: SELECT Query.* FROM (SELECT {spr.*}, {adr.*}, {adrt.*}, {cty.*}, {com.*}, {comt.*}, spft.[Rank] AS [Rak], Row_number() OVER(ORDER BY spft.[Rank] DESC) AS rownum FROM customer spr INNER JOIN CONTAINSTABLE ( customerfulltext , computedfulltextindex , '" + parsedSearchTerm + @"' ) AS spft ON spr.customerid = spft.[Key] LEFT JOIN [Address] adr ON adr.customerid = spr.customerid INNER JOIN [AddressType] adrt ON adrt.addresstypeid = adr.addresstypeid INNER JOIN [City] cty ON cty.cityid = adr.cityid LEFT JOIN [Communication] com ON com.customerid = spr.customerid INNER JOIN [CommunicationType] comt ON comt.communicationtypeid = com.communicationtypeid) as Query ORDER BY Query.[Rank] DESC This is how I setup the query: var items = GetCurrentSession() .CreateSQLQuery(query) .AddEntity("spr", typeof(Customer)) .AddJoin("adr", "spr.addresses") .AddJoin("adrt", "adr.Type") .AddJoin("cty", "adr.City") .AddJoin("com", "spr.communicationItems") .AddJoin("comt", "com.Type") .List<Customer>(); What happens now is, that the query returns customers twice (or more), I assume this is because of the joins since for each customer address, communicationItem (e.g. phone, email), a new sql row is returned. In this case I thought I could use the DistinctRootEntityResultTransformer. var items = GetCurrentSession() .CreateSQLQuery(query) .AddEntity("spr", typeof(Customer)) .AddJoin("adr", "spr.addresses") .AddJoin("adrt", "adr.Type") .AddJoin("cty", "adr.City") .AddJoin("com", "spr.communicationItems") .AddJoin("comt", "com.Type") .SetResultTransformer(new DistinctRootEntityResultTransformer()) .List<Customer>(); Doing so an exception is thrown. This is because I try to list customers .List<Customer>() but the transformer returns only entities of the last join added. E.g. in the case above, the entity with alias "comt" is returned when doing .List() instead of .List(). If I would switch last join with the join alias "cty", then the transformer returns a list of cities only... Anyone knows how I can return a clean list of customers in this case?

  • Specifying Locations relative to the context XML in Spring

    - by Daisuke Shimamoto
    Is there a way to reference a properties file relative to the Spring's context file itself? What I want to do is the below: <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <!-- I want the below to be relative to this context XML file. --> <value>app.properties</value> </list> </property> </bean> I was imagining something like ${contextpath} that I could prepend to the above "app.properties" but couldn't find anything helpful. Thanks.

  • Call other activities in an activity?

    - by Mohit Deshpande
    Say I have 2 activities (ActivityOne and ActivityTwo). How would I call ActivityTwo from ActivityOne? Then how would I return to ActivityOne from ActivityTwo? For example, I have a listview with all the contacts on the host phone. When I tap on a contact, another activity shows information and allows editing of that contact. Then I could hit the back button, and I would go back to the exact state that ActivityOne was in before I called ActivityTwo. I was thinking an Intent object, but I am not sure. Could someone post some code?

  • Is this the right way to have "global" parameters for my servlets?

    - by Geo
    If I have: <context-param> <param-name>SomeParam</param-name> <param-value>SomeValue</param-value> </context-param> in my web.xml, is this the servlet way of specifying options ( like in the way a config file is used ) , or am I doing something wrong? I know about init-param that can be specified for a servlet, but I'd like o make sure some values are the same for all the servlets.

  • Noob question about hibernate criteria

    - by Dimitri
    Hello, I have a class called User which has 2 properties : login/password. I am trying to authenticate a user in my application using hibernate criteria but my request doesn't work. [EDIT] The returned value is NULL. I have two users in my database for testing. Here is my code : @Override public User authenticate(String login, String password) throws NullPointerException { Session session = this.getSession(); User user = (User) session .createCriteria(User.class) .add( Restrictions.and( Property.forName("login").eq(login), Property.forName("password").eq(password) )).uniqueResult(); if (user == null){ throw new NullPointerException("User not found"); } return user; } Can someone tells me what is wrong with my code? Happy new Year 2011 !!

  • Positioning child panels using FlowLayout

    - by extro
    I have two panels: main_panel child_panel The main_panel layout is set using: main_panel.setLayout(flowlayout) I then added child_panel to main_panel: main_panel.add(child_panel) The child_panel gets added to main_panel but its position is at the cross-section of horizontal midpoint and top vertical section of screen. I want child_panel to be at the top left corner, something I could have done by using child_panel.setlocation(a,b) method, if I have set the layout of main_panel as null. I have used FlowLayout here because I want components in the JPanel to keep adjusting with the size of JFrame. So can I add child_panel to main_panel at the exact location I want, even if I set the Layout of main_panel as not null?

  • How to calculate the y-pixels of someones weight on a graph? (math+programming question)

    - by RexOnRoids
    I'm not that smart like some of you geniuses. I need some help from a math whiz. My app draws a graph of the users weight over time. I need a surefire way to always get the right pixel position to draw the weight point at for a given weight. For example, say I want to plot the weight 80.0(kg) on the graph when the range of weights is 80.0 to 40.0kg. I want to be able to plug in the weight (given I know the highest and lowest weights in the range also) and get the pixel result 400(y) (for the top of the graph). The graph is 300 pixels high (starts at 100 and ends at 400). The highest weight 80kg would be plot at 400 while the lowest weight 40kg would be plot at 100. And the intermediate weights should be plotted appropriately. I tried this but it does not work: -(float)weightToPixel:(float)theWeight { float graphMaxY = 400; //The TOP of the graph float graphMinY = 100; //The BOTTOM of the graph float yOffset = 100; //Graph itself is offset 100 pixels in the Y direction float coordDiff = graphMaxY-graphMinY; //The size in pixels of the graph float weightDiff = self.highestWeight-self.lowestWeight; //The weight gap float pixelIncrement = coordDiff/weightDiff; float weightY = (theWeight*pixelIncrement)-(coordDiff-yOffset); //The return value return weightYpixel; }

  • Array returning Null values

    - by Nick Gibson
    Dunno why it is...heres the coding for it. http://pastebin.org/301343 I know theres a lot of repetitiveness in the coding...but its because the arrays were retuning null so I got tired of messing with them. Everything works until it reaches line 224, which returns null values.

  • AtomicInteger for limited sequnce generation

    - by satish
    How can we use AtomicInteger for limited sequence generation say the sequence number has to be between 1 to 60. Once the sequece reaches 60 it has to start again from 1. I wrote this code though not quite sure wether this is thread safe or not? public int getNextValue() { int v; do { v = val.get(); if ( v == 60) { val.set(1); } } while (!val.compareAndSet(v , v + 1)); return v + 1; }

  • Does iBatis enforce a primary key on my table?

    - by Yousui
    Hi guys, I'm working on a legacy project. The database is poorly designed. I want to change the DB layer now. The first think go through my mind is hibernate, but I hibernate need a primary key on my table. In fact some of my table does not have primary key. So I did a google search and I find iBatis, it's sounds very good with it. But I don't know whether iBatis enforce a primary key on my table? Thanks.

  • Eclipse and SVN: Missing .project file.

    - by DHC
    Hi, I'm working on a uni project with a few other people using SVN. Much to my annoyance the .project file was removed from the repository since "it contains platform specific information". However, this has obviously broken my setup in Eclipse, giving me the error: Problems occurred opening the selected resources. The project description file (.project) for '___' is missing. This file contains important information about the project. The project will not function properly until this file is restored. Any suggestions? Thank you.

  • Is map/collection order stable between calls?

    - by John
    If I have a hash map and iterate over the objects repeatedly, is it correct that I'm not guaranteed the same order for every call? For example, could the following print two lines that differ from each other: Map<String,Integer> map = new HashMap<String,Integer>() {{ put("a", 1); put("b", 2); put("c", 3); }}; System.out.println(map); System.out.println(map); And is this the case for sets and collections in general? If so, what's the best way in case you have to iterate twice over the same collection in the same order (regardless of what order that is)? I guess converting to a list.
