  • Reading a part of a alpha numeric string in SQL

    - by novice
    I have a table with one column " otname " table1.otname contains multiple rows of alpha-numeric string resembling the following data sample: 11.10.32.12.U.A.F.3.2.21.249.1 2001.1.1003.8281.A.LE.P.P 2010.1.1003.8261.A.LE.B.B I want to read the fourth number in every string ( part of the string in bold ) and write a query in Oracle 10g to read its description stored in another table. My dilemma is writing the first part of the query.i.e. choosing the fourth number of every string in a table My second query will be something like this: select description_text from table2 where sncode = 8281 -- fourth part of the data sample in every string Many thanks. novice

  • Using a backwards relation (i.e FOO_set) for ModelChoiceField in Django

    - by Bwmat
    I have a model called Movie, which has a ManyToManyField called director to a model called Person, and I'm trying to create a form with ModelChoiceField like so: class MovieSearchForm(forms.Form): producer = forms.ModelChoiceField(label='Produced by', queryset=movies.models.Person.producer_set, required=False) but this seems to be failing to compile (I'm getting a ViewDoesNotExist exception for the view that uses the form, but it goes away if I just replace the queryset with all the person objects), I'm guessing because '.producer_set' is being evaluated too 'early'. How can I get this work? here are the relevant parts of the movie/person classes: class Person(models.Model): name = models.CharField(max_length=100) class Movie(models.Model): ... producer = models.ForeignKey(Person, related_name="producers") director = models.ForeignKey(Person, related_name="directors") What I'm trying to do is get ever Person who is used in the producer field of some Movie.

  • How to design this simple database?

    - by Vafello
    I have 2 tables - one storing user information (id, username, password) and the second one storing information about events (id, name, description, date, username(represents the user who created the event)). I would like to implement 'favourite events' functionality. This would allow the user to store his favourite events and later display them in a list. I am not sure how to implement this in terms of design. I need a simple solution. Something like storing the IDs of favourite events in a field in the user table. I am using mysql and php. Can anyone point me to the right direction?

  • show the list of usernames inside a div

    - by Mr_Green
    I am new to jQuery. In my project, I created one Class User in which the code is as shown below: static ConcurrentDictionary<string, User> _users = new ConcurrentDictionary<string, User>(); // // some function to add values to _users list // public List<User> GetConnectedUsers() { return _users.Values.ToList(); } I want to show this list of values in div #showUsernames. How to do this by using jQuery? I tried the below which is not showing anything /*display your contacts*/ $('#showUsernames').append(function(){ chat.server.getConnectedUsers(); }); where chat.server(signalr) calls the server-side code(Chat class).. I think the solution has nothing to do with signalr. If the above description is not enough then you can go through my code here

  • Performing complex query with Dynamics CRM 4.0

    - by dub
    Hi, I have two custom entites, Product and ProductType, linked together in many-to-one relationship. Product has a lookup field to ProductType. I'm trying to write a query to fetch Type1 products with a price over 100, and Type2 products with a price lower than 100. Here's how I would do it in SQL : select * from Product P inner join ProductType T on T.Id = P.TypeId where (T.Code = 'Type1' and P.Price >= 100) or (T.Code = 'Type2' and P.Price < 100) I can't figure out a way to build a QueryExpression to do exactly that. I know I could do it with two queries, but I'd like to minimize roundtrips to the server. Is there a way to perform that query in only one operation ? Thanks!

  • Matching an IP address with an IP range?

    - by Legend
    I have a MySQL table setup as follows: +---------------+-------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------------+-------------+------+-----+---------+----------------+ | ipaddress_s | varchar(15) | YES | MUL | NULL | | | ipaddress_e | varchar(16) | YES | | NULL | | +---------------+-------------+------+-----+---------+----------------+ where, ipaddress_s and ipaddress_e look something like: 4.100.159.0-4.100.159.255 Now is there a way I can actually get the row that contains a given IP address? For instance, given the IP address: "4.100.159.5", I want the above row to be returned. So I am trying for a query that looks something like this (but of course this is wrong because in the following I am considering IPs as strings): SELECT * FROM ranges WHERE ipaddress_s<"4.100.159.5" AND ipaddress_e>"4.100.159.5" Any suggestions?

  • mysql left join

    - by user1019538
    I have two table one is index and another is the price structure as under table : index : column : trandate ,indexcode Table : price : Column: trandate,symbol,price i want to know the missing price. I issue the query select i.trandate,i.indexcode,p.trandate,p.price from index i left join price p on i.trandate = p.trandate where p.symbol='ABC' and indexcode="New" the above query does not show the null date even though various price in missing in price table. Only reason i understand is that the index table does not have the symbol field that's why...but as per theory if you want to show all the rows of one table and only the match value of another table then use the left or right join query...please anybody can help

  • Get Average Using LINQ

    - by obautista
    Hoping someone can help me with the LINQ syntax to calculate an average. For example, I have the following LINQ query: var rates = from rating in ctx.Rates where rating.Id == Id select new { UserId = rating.UserId, Rating = rating.Rating }; If 10 records are returned, I need to calculate average on the Rating field. It is defined as as a Double in my DB. I am using LINQ to EF. So I would be assigning the UserId, MiscId, and the Rating would be the average on the records returned. I am passing one object back to the client code.

  • What is XcvPort (used in OpenPrinter function)

    - by RiskX
    I'm usin the OpenPrinter function and the first parameter the function gets called "pPrinterName" and that's it's MSDN description: [in] Pointer to a null-terminated string that specifies the name of the printer or print server, the printer object, the XcvMonitor, or the XcvPort. For a printer object use: PrinterName,Job xxxx. For an XcvMonitor, use: ServerName,XcvMonitor MonitorName. For an XcvPort, use: ServerName,XcvPort PortName. Obviously I'm interested in the bold part. What exactly is XcvPort? I know it seems like a question of lazy person but I really couldn't find info abou this concept. If I would like to open a printer on port ABC I should write: "\\MySrever,XcvPort ABC"? Thank you for your answers!

  • hidden form element not bound?

    - by csetzkorn
    Is it standard/intended behaviour that the value of a hidden form field is not bound to the view model (nor is a query string value)? Example: <%= Html.Hidden("test", "13" )%> if my poco view model contains a property test it should be bound shouldn't it?! i have to set it explicitely in the controller at the moment which kind of defeats the objective doesn't it? bla( formviewmodel m, string test) { m.test = test; } any feedback appreciated. thanks! christian

  • ILNumerics multiply complex with matrix<double>

    - by nik
    I m looking at ILNumerics to translate some matlab code into c#. How would I multiply a complex and a double? Simplified description: In Matlab: A=[1 2 3] i*A*A' Returns a complex number. How would I do the same in ILNumerics: ILArray<double> A = ILMath.array(1.0, 2.0, 3.0); complex B = complex.i * ILMath.multiply(A,A.T); Throws the error: Operator '*' cannot be applied to operands of type 'ILNumerics.complex' and 'ILNumerics.ILRetArray<double>' Update This works: double C = 14.0; complex D = complex.i * C; But shouldnt: ILMath.multiply(A,A.T) also return 14.0?

  • (Django) Trim whitespaces from charField

    - by zardon
    How do I strip whitespaces (trim) from the end of a charField in Django? Here is my Model, as you can see I've tried putting in clean methods but these never get run. I've also tried doing name.strip(), models.charField().strip() but these do not work either. Is there a way to force the charField to trim automatically for me? Thanks. class Employee(models.Model): """(Workers, Staff, etc)""" name = models.CharField(blank=True, null=True, max_length=100) # This never gets run def clean_variable(self): data = self.cleaned_data['variable'].strip() return data def __unicode__(self): return self.name class Meta: verbose_name_plural = 'Employees' # This never gets run either class EmployeesForm(forms.ModelForm): class Meta: model = Employee def clean_description(self): #if not self.cleaned_data['description'].strip(): # raise forms.ValidationError('Your error message here') self.cleaned_data['name'].strip()

  • Parameterise Service start option in WiX installer

    - by Jamiec
    I have a ServiceInstall component in a WiX installer where I have a requirement to either start auto or demand depending on parameters passed into the MSI. So the Xml element in question is <ServiceInstall Vital="yes" Name="My Windows Service" Type="ownProcess" Account="[SERVICEUSERDOMAIN]\[SERVICEUSERNAME]" DisplayName="My Service" Password="[SERVICEUSERPASSWORD]" Start="demand" Interactive="no" Description="Something interesting here" Id="Service" ErrorControl="ignore"></ServiceInstall> WiX will not allow using a PArameter for the Start attribute, so Im stuck with completely suplicating the component with a condition, eg/ <Component Id="ServiceDemand" Guid="{E204A71D-B0EB-4af0-96DB-9823605050C7}" > <Condition>SERVICESTART="demand"</Condition> ... and completely duplicating the whole component, with a different setting for Start and a different Condition. Anyone know of a more elegant solution? One where I don;t have to maintain 2 COmponents whjich do exactly the same thing except the Attribute for Start?

  • Java and Different Types of Stacks

    - by Rarge
    Currently the only stack I know anything about is Vector, I normally use this in place of an array but I understand that there is other types of stacks and they all suit different jobs. The project I am currently working on requires me to be inserting objects in a certain position inside a stack, not always the front of the stack and I am under the impression that a Vector may not be the best class for this job. Could somebody please give me a brief description of the other types of stacks available to me with the Java language and their advantages and disadvantages? Are these names homogeneous? E.g. Are they only used in the Java language or are they used as general terms in Computer Science? Thank you

  • Maximum number of bytes that can be sent on a TCP connection

    - by iamrohitbanga
    I initially assumed that since tcp has a sequence number field of 32 bits and each byte sent on a tcp connection is labeled with a unique number, maximum number of bytes that can be sent on a tcp connection is about 2^32-1 or 2^32-2 (which?). but now I feel that since TCP is a sliding window protocol, the wraparound of sequence numbers during the connection should not have an affect on the maximum number of bytes that can be sent over a tcp connection as long as the when wraparound occurs the old packet is no longer in the network (it is sent after 2*MSL). What is the correct answer?

  • Discrete event simulation framework for .NET

    Does anyone have an experience with some discrete event simulation library that could be used in .NET (C#)? Despite the basic functionality for queing events and dispatching them, it would be fine to have some non-deterministic behavior (e.g. failures simulation). I have some tips and I am even considering to write my own, but first, I would like to collect some recomendations. Thanks. Additional info: i'm not looking explicitly for free product, however, the prize matters :) Just to precise the field i need to map, here is the example of a product: http://www.holushko.com/index.html

  • How to bring out checboxes based on drop down list selection from DB

  • Strange Java Coding??? Class in class???

    - by poeschlorn
    Hi guys, I got a question about Java coding in general... In some sample codes there are methods and classes declared WITHIN other methods and/or classes.... I've never heard/red about this...what effect does this kind of programming have? Wouldn't it be better to write down classes in a seperate file and methods side by side and not within each other (like every book tells you)? What are the advantages and disadvantages of this kind of programming? Here's an example of what I mean: Handler mHandler = new Handler() { public void handleMessage(android.os.Message msg) { TextView textView = (TextView) findViewById(R.id.description); textView.setText(mRoad.mName + " " + mRoad.mDescription); MapOverlay mapOverlay = new MapOverlay(mRoad, mapView); List<Overlay> listOfOverlays = mapView.getOverlays(); listOfOverlays.clear(); listOfOverlays.add(mapOverlay); mapView.invalidate(); }; };

  • How do you set a double value to a "non-value"

    - by Ankur
    I have two double data elements in an object. Sometimes they are set with a proper value and sometimes not. When the form field from which they values are received is not filled I want to set them to some value that tells me, during the rest of the code that the form fields were left empty. I can't set the values to null as that gives an error, is there some way I can make them 'Undefined'. PS. Not only am I not sure that this is possible, it might not also make sense. But if there is some best practice for such a situation I would be keen to hear it.
