  • Binding DataTemplates (or another aproach)

    - by Bataglião
    Hi all, I'm having some troubles trying to dynamically generate content in WPF and after it bind data. I have the following scenario: TabControl - Dynamically generated TabItems through DataTemplate - inside TabItems, I have dynamic content generated by DataTemplate that I wish to bind (ListBox). The code follows: ::TabControl <TabControl Height="252" HorizontalAlignment="Left" Name="tabControl1" VerticalAlignment="Top" Width="458" Margin="12,12,12,12" ContentTemplate="{StaticResource tabItemContent}"></TabControl> ::The Template for TabControl to generate TabItems <DataTemplate x:Key="tabItemContent"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="*" /> </Grid.RowDefinitions> <ListBox ItemTemplate="{StaticResource listBoxContent}" ItemsSource="{Binding}"> </ListBox> </Grid> </DataTemplate> ::The template for ListBox Inside each TabItem <DataTemplate x:Key="listBoxContent"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="22"/> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Image Grid.Column="0" Source="{Binding Path=PluginIcon}" /> <TextBlock Grid.Column="1" Text="{Binding Path=Text}" /> </Grid> </DataTemplate> So, when I try to do this on code inside a loop to create the tabitems: TabItem tabitem = tabControl1.Items[catIndex] as TabItem; tabitem.DataContext = plugins.ToList(); where 'plugins' is an Enumerable The ListBox is not bounded. I tried also to find the ListBox inside the TabItem to set the ItemSource property but no success at all. Someone have an idea on how to do that? Thanks in advance.

  • What are the best options for a root filesystem hosted on SSD under Linux

    - by stsquad
    I'm working on an embedded system which is going to be booting and hosting it's rootfs on an SSD disk. We are currently looking at using Intel X-18M SSDs. The file system structure will have a fairly static /usr section (modulo software upgrades) and an active /var and /var/log for maintaining state and logging. Given the wear-levelling done by the underlying flash does having separate partitions help or hinder? As modern SSDs appear as straight block devices and hide their mapping magic behind their firmware is there any point trying to optimise the choice of file-system that sits on-top of the SSD? Finally does enable SMART monitoring make any sense in this context or are their SSD specific ways of determining the underlying health of the storage hardware?

  • t-sql most efficient row to column? for xml path, pivot

    create table _orders ( OrderId int identity(1,1) primary key nonclustered ,CustomerId int ) create table _details ( DetailId int identity(1,1) primary key nonclustered ,OrderId int ,ProductId int ) insert into _orders (CustomerId) select 1 union select 2 union select 3 insert into _details (OrderId,ProductId) select 1,100 union select 1,158 union select 1,234 union select 2,125 union select 3,105 union select 3,101 union select 3,212 union select 3,250 -- select orderid ,REPLACE(( SELECT ' ' + CAST(ProductId as varchar) FROM _details d WHERE d.OrderId = o.OrderId ORDER BY d.OrderId,d.DetailId FOR XML PATH('') ),'&#x20;','') as Products from _orders o I am looking for the most performant way to turn rows into columns. I have a requirement to output the contents of the db (not actual schema above, but concept is similar) in both fixed width and delimited formats. The above FOR XML PATH query gives me the result I want, but when dealing with anything other than small amounts of data, can take awhile. I've looked at pivot but most of the examples I have found are aggregating information. I just to combine the child rows and tack them onto the parent. For example, for an order it would need to output: OrderId,Product1,Product2,Product3,etc Thoughts or suggestions? I am using SQL Server 2k5.

  • cgi.FieldStorage always empty - never returns POSTed form Data

    - by Dan Carlson
    This problem is probably embarrassingly simple. I'm trying to give python a spin. I thought a good way to start doing that would be to create a simple cgi script to process some form data and do some magic. My python script is executed properly by apache using mod_python, and will print out whatever I want it to print out. My only problem is that cgi.FieldStorage() is always empty. I've tried using both POST and GET. Each trial I fill out both form fields. <form action="pythonScript.py" method="POST" name="ARGH"> <input name="TaskName" type="text" /> <input name="TaskNumber" type="text" /> <input type="submit" /> </form> If I change the form to point to a perl script it reports the form data properly. The python page always gives me the same result: number of keys: 0 #!/usr/bin/python import cgi def index(req): pageContent = """<html><head><title>A page from""" pageContent += """Python</title></head><body>""" form = cgi.FieldStorage() keys = form.keys() keys.sort() pageContent += "<br />number of keys: "+str(len(keys)) for key in keys: pageContent += fieldStorage[ key ].value pageContent += """</body></html>""" return pageContent I'm using Python 2.5.2 and Apache/2.2.3. This is what's in my apache conf file (and my script is in /var/www/python): <Directory /var/www/python/> Options FollowSymLinks +ExecCGI Order allow,deny allow from all AddHandler mod_python .py PythonHandler mod_python.publisher </Directory>

  • How do I forward `<Ctrl>-<Tab>` in Konsole?

    - by M. Tibbits
    I want to use intelligent tabbing in Emacs in C++ mode, but I also want to be able to insert a tab character when necessary. From other posts, I gather that the easiest way is to bind <Ctrl>-<Tab> to indent. However, it appears that Konsole in KUbuntu won't forward the <Ctrl>? My current .emacs file contains: (defun my-c-mode-common-hook () (setq c++-tab-always-indent t) (setq tab-width 4) (setq indent-tabs-mode t) ) (add-hook 'c-mode-common-hook 'my-c-mode-common-hook) (global-set-key [C-tab] 'self-insert-command) So I believe that this will bind <Ctrl>-<Tab> to inserting a tab character. However, when I run: <Ctrl>-h k <Ctrl>-<Tab> Emacs only reports that I pressed the tab key. Is there some option to Konsole (which I have searched through to no avail) or global preferences in KUbuntu that I need to set so that the <Ctrl>- is also forwarded? (It certainly forwards all of the other <Ctrl>-blah commands.)

  • Confusion about WPF binding...

    - by Vladislav
    I am trying to bind a 2D array of buttons arranged in stackpanels to a 2D ObservableCollection... Yet, I'm afraid I don't understand something very elementary about binding. My XAML: <Window.Resources> <DataTemplate x:Key="ItemsAsButtons"> <Button Content="{Binding}" Height="100" Width="100"/> </DataTemplate> <DataTemplate x:Key="PanelOfPanels"> <ItemsControl ItemsSource="{Binding Path=DayNumbers}" ItemTemplate=" {DynamicResource ItemsAsButtons}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </DataTemplate> </Window.Resources> ... <ItemsControl x:Name="DaysPanel" Grid.ColumnSpan="7" Grid.Row="2" ItemTemplate="{DynamicResource PanelOfPanels}"/> My C# code: The backend: /// <summary> /// Window BE for Calendar.xaml /// </summary> public partial class Calendar : Window { private CalendarViewModel _vm; public Calendar() { InitializeComponent(); _vm = new CalendarViewModel(); this.DataContext = _vm; } } The ViewModel: class CalendarViewModel { CalendarMonth _displayedMonth; EventCalendar _calendar; public CalendarViewModel() { _displayedMonth = new CalendarMonth(); } public ObservableCollection<ObservableCollection<int>> DayNumbers { get { return _displayedMonth.DayNumbers; } } } I'm trying to populate the buttons with values from CalendarViewModel.DayNumbers - yet the buttons do not appear. I'm clearly doing something wrong with my binding.

  • Is it possible to build a JPA entity by extending a POJO?

    - by Freiheit
    Lets say I have the following POJO: public class MyThing { private int myNumber; private String myData; //assume getter/setter methods } Is it now possible to extend this POJO as a JPA entity? @Entity @Table(name = "my_thing") public class MyThingEntity extends MyThing implements Serializable { @Column(name = "my_number") //????????? @Column(name = "my_data") //???????? } I want to keep the POJO separate from the JPA entity. The POJO lives in a different project and is often used without a persistence layer, my project wants to persist it in a database and do so without the overhead of mapping from a POJO to an entity and back. I understand that JPA entities are POJOs, but in order to use it I would have to include a library that implements javax.persistence and the other projects using the same base object have no use for a persistence layer. Is this possible? Is this a good idea?

  • What are some typing patterns using a standard QWERTY keyboard that work well for you as a programme

    - by OrbMan
    After hunting and pecking for about 35 years, I have decided to learn to type. I am learning QWERTY and have learned about 2/3 of the letters so far. While learning, I have noticed how asymmeterical the keyboard is, which really bothers me. (I will probably switch to a symmetrical keyboard eventually, but for now am trying to do everything as standard and "correct" as possible.) Although I am not there yet in my lessons, it seems that many of the keys I am going to use as a C# web developer are supposed to be typed by the pinky of my right hand. Are there any typing patterns you have developed that are more ergonomic (or faster) when typing large volumes of code rife with braces, colons, semi-colons and quotes? Or, should I just accept the fact that every other key is going to be hit with my right pinky? It is not that speed is such a huge concern, as much as that it seems so inefficient to rely on one finger so much... As an example, some of the conventions I use as a hunt and pecker, like typing open and close braces right away with my index and middle finger, and then hitting the left arrow key to fill in the inner content, don't seem to work as well with just a pinky. What are some typing patterns using a standard QWERTY keyboard that work really well for you as a programmer? Update: US layout and I use home row Update 2: Despite my best efforts to the contrary, people are interpreting this questionas "how do I learn to type" or "what keyboard should I use". Take it as a given, that I will learn to type, and that I will be doing so on a standard QWERTY layout keyboard, not DVORAK. I am interested in aquiring a skill that will be useful wherever I go.

  • SQL query to get latest record for all distinct items in a table

    - by David Buckley
    I have a table of all sales defined like: mysql> describe saledata; +-------------------+---------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------------+---------------------+------+-----+---------+-------+ | SaleDate | datetime | NO | | NULL | | | StoreID | bigint(20) unsigned | NO | | NULL | | | Quantity | int(10) unsigned | NO | | NULL | | | Price | decimal(19,4) | NO | | NULL | | | ItemID | bigint(20) unsigned | NO | | NULL | | +-------------------+---------------------+------+-----+---------+-------+ I need to get the last sale price for all items (as the price may change). I know I can run a query like: SELECT price FROM saledata WHERE itemID = 1234 AND storeID = 111 ORDER BY saledate DESC LIMIT 1 However, I want to be able to get the last sale price for all items (the ItemIDs are stored in a separate item table) and insert them into a separate table. How can I get this data? I've tried queries like this: SELECT storeID, itemID, price FROM saledata WHERE itemID IN (SELECT itemID from itemmap) ORDER BY saledate DESC LIMIT 1 and then wrap that into an insert, but it's not getting the proper data. Is there one query I can run to get the last price for each item and insert that into a table defined like: mysql> describe lastsale; +-------------------+---------------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------------+---------------------+------+-----+---------+-------+ | StoreID | bigint(20) unsigned | NO | | NULL | | | Price | decimal(19,4) | NO | | NULL | | | ItemID | bigint(20) unsigned | NO | | NULL | | +-------------------+---------------------+------+-----+---------+-------+

  • Phantom updates due to decimal precision on calculated properties

    - by Jamie Ide
    This article describes my problem. I have several properties that are calculated. These are typed as decimal(9,2) in SQL Server and decimal in my C# classes. An example of the problem is: Object is loaded with a property value of 14.9 A calculation is performed and the property value is changed to 14.90393 When the session is flushed, NHibernate issues an update because the property is dirty Since the database field is decimal (9,2) the stored value doesn't change Basically a phantom update is issued every time this object is loaded. I don't want to truncate the calculations in my business objects because that tightly couples them to the database and I don't want to lose the precision in other calculations. I tried setting scale and precision or CustomType("Decimal(9,2)") in the mapping file but this appears to only affect schema generation. My only reasonable option appears to be creating an IUserType implementation to handle this. Is there a better solution?

  • Converter problem with XmlDataProvider

    Sorry for this, I've just started programming with wpf. I can't seem to figure out why the following xaml displays "System.Xml.XmlElement" instead of the actual xml node content. This is displayed 5 times in the listbox whenever I run it. Not sure where I'm going wrong... <Window x:Class="TestBinding.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Window.Resources> <XmlDataProvider x:Key="myXmlSource" XPath="/root"> <x:XData> <root xmlns=""> <name>Steve</name> <name>Arthur</name> <name>Sidney</name> <name>Billy</name> <name>Steven</name> </root> </x:XData> </XmlDataProvider> <DataTemplate x:Key="shmooga"> <TextBlock Text="{Binding}"/> </DataTemplate> </Window.Resources> <Grid> <ListBox ItemTemplate="{StaticResource shmooga}" ItemsSource="{Binding Source={StaticResource myXmlSource}, XPath=name}"> </ListBox> </Grid> </Window> Any help would be very much appreciated.

  • Date format strings in .Net and Java

    - by mizipzor
    I have an application that runs on both C# .Net and Java. Two entirely separate but identical code bases. The problem Im having is formatting date and numbers. For example: A user running the .Net variant is inputting a date and a format string. The 26th of April 1986 is formatted 1986-04-26. The actual date, along with the format string, is serialized to an XML file. Later another user running the Java variant opens said XML file and looks at the date. I want them to look the same. Whats the best approach here? There doesnt seem to be a one-to-one mapping between Java and .Nets format strings. Should I limit the possible formats to a selection I know I can represent fully in both .Net and Java?

  • How do I specify Open ID Realm in spring security ?

    - by Salvin Francis
    We are using Spring security in our application with support for username / password based authentication as well as Open id based authentication. The issue is that google gives a different open id for the return url specified and we have at least 2 different entry points in our application from where open id is configured into our system. Hence we decided to use open id realm. http://blog.stackoverflow.com/2009/0...ue-per-domain/ http://groups.google.com/group/googl...unts-api?pli=1 how is it possible to integrate realm into our spring configuration/code ? This is how we are doing it in traditional openid library code: AuthRequest authReq = consumerManager.authenticate(discovered, someReturnToUrl,"http://www.example.com"); This works and gives same open id for different urls from our site. our configuration: Code: ... <http auto-config="false"> <!-- <intercept-url> tags are here --> <remember-me user-service-ref="someRememberedService" key="some key" /> <form-login login-page="/Login.html" authentication-failure-url="/Login.html?error=true" always-use-default-target="false" default-target-url="/MainPage.html"/> <openid-login authentication-failure-url="/Login.html?error=true" always-use-default-target="true" default-target-url="/MainPage.html" user-service-ref="someOpenIdUserService"/> </http> ... <beans:bean id="someOpenIdUserService" class="com.something.MyOpenIDUserDetailsService"> </beans:bean> <beans:bean id="openIdAuthenticationProvider" class="com.something.MyOpenIDAuthenticationProvider"> <custom-authentication-provider /> <beans:property name="userDetailsService" ref="someOpenIdUserService"/> </beans:bean> ...

  • NHibernate Child items query using Parent Id

    - by thorkia
    So I have a set up similar to this questions: Parent Child Setup Everything works great when saving the parent and the children. However, I seem to have a problem when selecting the children. I can't seem to get all the children with a specific parent. This fails with: NHibernate.QueryException: could not resolve property: ParentEntity_id of: Test.Data.ChildEntity Here is my code: public IEnumerable<ChildEntity> GetByParent(ParentEntity parent) { using (ISession session = OrmHelper.OpenSession()) { return session.CreateCriteria<ChildEntity>().Add(Restrictions.Eq("ParentEntity_id ", parent.Id)).List<ChildEntity>(); } } Any help in building a proper function to get all the items would be appreciated. Oh, I am using Fluent NHibernate to construct the mappings - version 1 RTM and NHibernate 2.1.2 GA If you need more information, let me know. As per you request, my fluent mappings: public ParentEntityMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Code).UniqueKey("ukCode"); HasMany(x => x.ChildEntity).LazyLoad() .Inverse().Cascade.SaveUpdate(); } public ChildEntityMap() { Id(x => x.Id); Map(x => x.Amount); Map(x => x.LogTime); References(x => x.ParentEntity); } That maps to the following 2 tables: CREATE TABLE "ParentEntity" ( Id integer, Name TEXT, Code TEXT, primary key (Id), unique (Code) ) CREATE TABLE "ChildEntity" ( Id integer, Amount NUMERIC, LogTime DATETIME, ParentEntity_id INTEGER, primary key (Id) ) The data store in SQLite.

  • MySQL: order by and limit gives wrong result

    - by Larry K
    MySQL ver 5.1.26 I'm getting the wrong result with a select that has where, order by and limit clauses. It's only a problem when the order by uses the id column. I saw the MySQL manual for LIMIT Optimization My guess from reading the manual is that there is some problem with the index on the primary key, id. But I don't know where I should go from here... Question: what should I do to best solve the problem? Works correctly: mysql> SELECT id, created_at FROM billing_invoices WHERE (billing_invoices.account_id = 5) ORDER BY id DESC ; +------+---------------------+ | id | created_at | +------+---------------------+ | 1336 | 2010-05-14 08:05:25 | | 1334 | 2010-05-06 08:05:25 | | 1331 | 2010-05-05 23:18:11 | +------+---------------------+ 3 rows in set (0.00 sec) WRONG result when limit added!

  • DesignTime data not showing in Blend when bound against CollectionViewSource

    - by bitbonk
    I have datatemplate for a viewmodel where an itemscontrol is bound again a CollectionViewSource (to enable sorting in xaml). <DataTemplate x:Key="equipmentDataTemplate"> <Viewbox> <Viewbox.Resources> <CollectionViewSource x:Key="viewSource" Source="{Binding Modules}"> <CollectionViewSource.SortDescriptions> <scm:SortDescription PropertyName="ID" Direction="Ascending"/> </CollectionViewSource.SortDescriptions> </CollectionViewSource> </Viewbox.Resources> <ItemsControl ItemsSource="{Binding Source={StaticResource viewSource}}" Height="{DynamicResource equipmentHeight}" ItemTemplate="{StaticResource moduleDataTemplate}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal" /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </Viewbox> </DataTemplate> I have also setup the UserControl where all of this is defined to provide designtime data d:DataContext="{x:Static vm:DesignTimeHelper.Equipment}"> This is basically a static property that gives me an EquipmentViewModel that has a list of ModuleViewModels (Equipment.Modules). Now as long as I bind to the CollectionViewSource the designtime data does not show up in blend 3. When I bind to the ViewModel collection directly <ItemsControl ItemsSource="{Binding Modules}" I can see the designtime data. Any idea what I could do?

  • Is this the right way to organize my database tables?

    - by Moss
    So I'm making a website that allows users to build contact lists. So their are users, the users have lists, and the lists have contacts. It seems to me that I need 3 tables for this but I just want to make sure. There would be a User table of course, and then a "List of Lists" table that has the username, and listname, as primary key along with whatever other info we want to attach to the lists as a whole. Finally, for lack of a better word, the List table which would again have the username/listname p.k., then the contact ID and notes and such that the user attaches to that contact on that specific list. I hope that is a clear explanation. For some reason I feel unsure about this arrangement. For one thing if the website becomes popular the List table could swell to billions of rows. And it also feels a little weird that everybody's list info is all jumbled up in the same table. I suppose I could create separate tables for each user and even for each list but that seems like a bad idea for other reasons. My db explanation assumes I can use foreign keys on my tables which at the moment isn't actually an option. If I can't get InnoDB tables enabled I will probably use ID's for the lists instead of depending on a compound key. Maybe I should do this anyway?

  • NHibernate ManyToMany Relationship Cascading AllDeleteOrphan StackOverflowException

    - by Chris
    I have two objects that have a ManyToMany relationship with one another through a mapping table. Though, when I try to save it, I get a stack overflow exception. The following is the code for the mappings: //EventMapping.cs HasManyToMany(x => x.Performers).Table("EventPerformer").Inverse().Cascade.AllDeleteOrphan().LazyLoad().ParentKeyColumn("EventId").ChildKeyColumn("PerformerId"); //PerformerMapping.cs HasManyToMany<Event>(x => x.Events).Table("EventPerformer").Inverse().Cascade.AllDeleteOrphan().LazyLoad().ParentKeyColumn("PerformerId").ChildKeyColumn("EventId"); When I change the performermapping.cs to Cascade.None() I get rid of the exception but then my Event Object doesn't have the performer I associate with it. //In a unit test, paraphrased event.Performers.Add(performer); //Event eventRepository.Save<Event>(event); eventResult = eventRepository.GetById<Event>(event.id); //Event eventResult.Performers[0]; //is null, should have performer in it How should I be writing this properly? Thanks

  • Problems with ASP.NET State Service version; state service is 1.1, website is 3.5

    - by Mick Byrne
    Hi there, I have a ASP.NET 3.5 website running on Windows Server 2003 and I'm using the ASP.NET State Service to manage sessions. It will appear to be working then I regularly get an error saying my code needs to have version 2.0 of the State Service running to work (I think that's what it said, I've temporarily switched back to storing sessions InProc). Refresh the page and the error goes away (for a bit, it's bound to come back). So I looked at the properties of the ASP.NET State Service in the Services interface and it's mapping to a .exe in the 1.1 framework folder: C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_state.exe There's a corresponding version in the 2.0 framework folder, but I don't know how to add it as a new service. I'm also not sure that adding the 2.0 version (and stopping and/or removing the 1.1 version) will solve the problem. Thanks in advance for any help anyone can provide. Mick

  • Computed properties in NHibernate

    - by Liron Levi
    I'm having a problem in mapping an existing data class member to the database.. I have a database table where one of the columns is a string type, but actually stores a comma separated list of numbers. My data class shows this field as a list of integers. The problem is that I couldn't find any hook in NHibernate that allows me to invoke the custom code that is required to replace the string field by the list and vice versa. To illustrate (simplified of course): The database table: CREATE TABLE dummy ( id serial, numlist text -- (can store values such as '1,2,3') ) The data class: class Dummy { public int Id; public List<int> NumbersList; } Can anyone help?

  • KeyUp processed for wrong control

    - by Mikael
    I have made a simple test application for the issue, two winforms each containing a button. The button on the first form opens the other form when clicked. It also subscribes to keyup events. The second form has its button set as "AcceptButton" and in the Clicked event we sleep for 1s and then set DialogResult to true (the sleep is to simulate some processing done) When enter is used to close this second form the KeyUp event of the button on the first form is triggered, even though the key was released well before the second had passed so the second form was still shown and focused. If any key other then enter is pressed in the second form the event is not triggered for the button on the first form. First form: public Form1() { InitializeComponent(); buttonForm2.KeyUp += new KeyEventHandler(cntKeyUp); } void cntKeyUp(object sender, KeyEventArgs e) { MessageBox.Show(e.KeyCode.ToString()); } private void buttonForm2_Click(object sender, EventArgs e) { using (Form2 f = new Form2()) { f.ShowDialog(); } } Second form: private void button1_Click(object sender, EventArgs e) { Thread.Sleep(1000); this.DialogResult = DialogResult.OK; } Does anyone know why the event is triggered for the button on the non active form and what can be done to stop this from happening?

  • Oracle why does creating trigger fail when there is a field called timestamp?

    - by Omar Kooheji
    I've just wasted the past two hours of my life trying to create a table with an auto incrementing primary key bases on this tutorial, The tutorial is great the issue I've been encountering is that the Create Target fails if I have a column which is a timestamp and a table that is called timestamp in the same table... Why doesn't oracle flag this as being an issue when I create the table? Here is the Sequence of commands I enter: Creating the Table: CREATE TABLE myTable (id NUMBER PRIMARY KEY, field1 TIMESTAMP(6), timeStamp NUMBER, ); Creating the Sequence: CREATE SEQUENCE test_sequence START WITH 1 INCREMENT BY 1; Creating the trigger: CREATE OR REPLACE TRIGGER test_trigger BEFORE INSERT ON myTable REFERENCING NEW AS NEW FOR EACH ROW BEGIN SELECT test_sequence.nextval INTO :NEW.ID FROM dual; END; / Here is the error message I get: ORA-06552: PL/SQL: Compilation unit analysis terminated ORA-06553: PLS-320: the declaration of the type of this expression is incomplete or malformed Any combination that does not have the two lines with a the word "timestamp" in them works fine. I would have thought the syntax would be enough to differentiate between the keyword and a column name. As I've said I don't understand why the table is created fine but oracle falls over when I try to create the trigger... CLARIFICATION I know that the issue is that there is a column called timestamp which may or may not be a keyword. MY issue is why it barfed when I tried to create a trigger and not when I created the table, I would have at least expected a warning. That said having used Oracle for a few hours, it seems a lot less verbose in it's error reporting, Maybe just because I'm using the express version though. If this is a bug in Oracle how would one who doesn't have a support contract go about reporting it? I'm just playing around with the express version because I have to migrate some code from MySQL to Oracle.

  • System.InvalidOperationException with SQlBulkCopy

    - by Pandiya Chendur
    I got the following error when executing bulkcopy. System.InvalidOperationException The given value of type String from the data source cannot be converted to type decimal of the specified target column. I use the following code. DataTable empTable = DataTemplate.GetEmployees(); DataRow row; for (int i = 0; i < gv.Rows.Count;i++ ) { row = empTable.NewRow(); string empName = gv.DataKeys[i].Values[0].ToString(); //first key string hourSalary = gv.DataKeys[i].Values[1].ToString(); //second key row["Emp_Name"] = empName; row["Hour_Salary"] = Convert.ToDecimal(hourSalary); row["Advance_amount"] = Convert.ToDecimal(0); row["Created_Date"] = Convert.ToDateTime(System.DateTime.Now.ToString()); row["Created_By"] = Convert.ToInt64(1); row["Is_Deleted"] = Convert.ToInt64(0); empTable.Rows.Add(row); } InsertintoEmployees(empTable, "Employee"); My SQL datatypes for the above fields are: Emp_Name nvarchar(50) , Hour_Salary numeric(18, 2), Advance_amount numeric(18, 2), Created_Date datetime, Created_By numeric(18, 0), Is_Deleted numeric(18, 0) I don't know what I am doing wrong.

  • How do you efficiently bulk index lookups?

    - by Liron Shapira
    I have these entity kinds: Molecule Atom MoleculeAtom Given a list(molecule_ids) whose lengths is in the hundreds, I need to get a dict of the form {molecule_id: list(atom_ids)}. Likewise, given a list(atom_ids) whose length is in the hunreds, I need to get a dict of the form {atom_id: list(molecule_ids)}. Both of these bulk lookups need to happen really fast. Right now I'm doing something like: atom_ids_by_molecule_id = {} for molecule_id in molecule_ids: moleculeatoms = MoleculeAtom.all().filter('molecule =', db.Key.from_path('molecule', molecule_id)).fetch(1000) atom_ids_by_molecule_id[molecule_id] = [ MoleculeAtom.atom.get_value_for_datastore(ma).id() for ma in moleculeatoms ] Like I said, len(molecule_ids) is in the hundreds. I need to do this kind of bulk index lookup on almost every single request, and I need it to be FAST, and right now it's too slow. Ideas: Will using a Molecule.atoms ListProperty do what I need? Consider that I am storing additional data on the MoleculeAtom node, and remember it's equally important for me to do the lookup in the molecule-atom and atom-molecule directions. Caching? I tried memcaching lists of atom IDs keyed by molecule ID, but I have tons of atoms and molecules, and the cache can't fit it. How about denormalizing the data by creating a new entity kind whose key name is a molecule ID and whose value is a list of atom IDs? The idea is, calling db.get on 500 keys is probably faster than looping through 500 fetches with filters, right?

  • ASP.NET MVC Map String Url To A Route Value Object

    - by mwgriffiths
    I am creating a modular ASP.NET MVC application using areas. In short, I have created a greedy route that captures all routes beginning with {application}/{*catchAll}. Here is the action: // get /application/index public ActionResult Index(string application, object catchAll) { // forward to partial request to return partial view ViewData["partialRequest"] = new PartialRequest(catchAll); // this gets called in the view page and uses a partial request class to return a partial view } Example: The Url "/Application/Accounts/LogOn" will then cause the Index action to pass "/Accounts/LogOn" into the PartialRequest, but as a string value. // partial request constructor public PartialRequest(object routeValues) { RouteValueDictionary = new RouteValueDictionary(routeValues); } In this case, the route value dictionary will not return any values for the routeData, whereas if I specify a route in the Index Action: ViewData["partialRequest"] = new PartialRequest(new { controller = "accounts", action = "logon" }); It works, and the routeData values contains a "controller" key and an "action" key; whereas before, the keys are empty, and therefore the rest of the class wont work. So my question is, how can I convert the "/Accounts/LogOn" in the catchAll to "new { controller = "accounts", action = "logon" }"?? If this is not clear, I will explain more! :) Matt This is the "closest" I have got, but it obviously wont work for complex routes: // split values into array var routeParts = catchAll.ToString().Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries); // feels like a hack catchAll = new { controller = routeParts[0], action = routeParts[1] };
