  • Single SQL Server Result Set from Query

    - by JamesC
    Hi Please advise on how to merge two results in to one using SQL Server 2005. I have the situation where an Account can have up to two Settlement Instructions and this have been modeled like so: The slim-ed down schema: Account --------------------- Id AccountName PrimarySettlementId (nullable) AlternateSettlementId (nullable) SettlementInstruction ---------------------- Id Name The output I want is a single result set with a select statement something along the lines of this which will allow me to construct some java objects in my Spring row mapper: select Account.Id as accountId, Account.AccountName as accountName, s1.Id as primarySettlementId, s1.Name as primarySettlementName, s2.Id as alternateSettlementId, s2.Name as alternateSettlementName I've tried various things but cannot find a way to get the result set merged in to one where the primary and alternate FK's are not null. Finally I have searched the forum, but nothing quite seems to fit with what I need.

  • Codeigniter - Is it ok to add functionality to the constructor in controllers?

    - by Irro
    I'm making a project where I want the user to search for shops in different cities and would like the url to be like this: domain/shop/city/name. So I created a controller in codeigniter called Shop. But I cant create a city function since the city part of the url changes dependent on city name. One easy way to do it would be to add a function called "search" and add the functionality there but then I get url's like: domain/shop/search/city/name which I really would like to avoid. So my question is if it's ok to add my functionality directly into the constructor to avoid that extra "search" part in the url? I'm afraid that there might be some performance tricks involved that potentially keeps the class in memory so the constructor will not be called every time.

  • hook_form for multiple content types defined by the same module

    - by pao13gate
    A new module 'foo' implements foo_node_info() where one or more new content types can be defined. If foo_node_info() defines two content types, namely a content type 'footypea' and a content type 'footypeb', how does one go about implementing hook_form() (what should the name of the "hook" be?) to configure each node's editing form? In the drupal example, the name of the new content type is the same as the module name. What happens in the above described example where two new content types are defined by the module? Should the implemented hook_form() function be of the form: footypea_form() and footypeb_form() ? (this doesn't seem to work) Or should you implement a single foo_form() function and within this create and return an array $form with elements $form['footypea'] and $form['footypeb'] that are in turn arrays of the individual form field definitions?

  • Install Python 2.6 without using installer on Win32

    - by prosseek
    I need to run a python script on a machine that doesn't have python installed. What I did was as follows. Copy python.exe, python26.dll, msvcr90.dll and Microsoft.VC90.CRT.manifest zip all the directory in LIBs directory as the python26.zip copy all the necessary dll/pyd file inside the DLL directory. It seems to work, but when I change the python26.zip to the other name such as pythonlib.zip. It cannot find the python library anymore. Q1 : What's the magic behind the python26.zip name? The python automatically finds a library inside a python26.zip but not with different name? Q2 : If I have python26.zip at the same directory where python.exe/python26.dll is, I don't need to add path sys.path.append(THE PATH TO python26.zip). Is it correct?

  • C# Reflection Question

    - by Jimbo
    This is a scenario created to help understand what Im trying to achieve. I am trying to create a method that returns the specified property of a generic object e.g. public object getValue<TModel>(TModel item, string propertyName) where TModel : class{ PropertyInfo p = typeof(TModel).GetProperty(propertyName); return p.GetValue(item, null); } The code above works fine if you're looking for a property on the TModel item e.g. string customerName = getValue<Customer>(customer, "name"); However, if you want to find out what the customer's group's name is, it becomes a problem: e.g. string customerGroupName = getValue<Customer>(customer, "Group.name"); Hoping someone can give me some insight on this way out scenario - thanks.

  • How to count the letters in a text with Javascript?

    - by Doguhanca
    I am currently trying to write a ''web application'' that has a simple text area inside, in which I want the letters of the text written to be pointed out. For example, if I write: ''How old are you? I am 19 years old'' I need a code to tell me how many 'A's and 'Y's and 'D's (and all letters of the alphabet from 0-26) are used in this sentence when I press a button on a HTML/ CSS page. Could you please tell me what I must write into my .JS file and what I should write into my .HTML file to do this with a click of a button when something is written in the ? I hope my explanation was detailed enough. Thanks! Edit (I'm very sorry for the problems I caused) - What I have done so far looks like this: HTML: <link rel="stylesheet" type="text/css" href="theme.css"> <meta charset="utf-8"> <script src="test.js" type="text/javascript"></script> <div class='header'> Al.Fa.Be </div> <div class='yaz'> <textarea></textarea> </div> <div class='description'> <a href='http://www.google.com'>Ara</a> </div> <div class='description2'> <input id="clickMe" type="button" value="Hesapla" onclick="doFunction();" /> </div> CSS: body{ background:white; } selection{ background:#CCC; } #clickMe{ background:#CCC; border:1px solid #333; } .header{ font-size:70px; font-weight:bold; font-family:Arial; color:#333; margin-left:580px; padding-top:200px; } textarea{ width:1210px; height:40px; color:black; margin-top:20px; margin-left:100px; padding-left:10px; padding-top:10px; font-size:18px; font-family:Arial; } .description{ background:#f2f2f2; padding:6px; width:50px; text-align:center; border:1px solid #ddd; font-family:Arial; margin-left:620px; margin-top:20px; font-size:14px; } .description a{ color:#555; text-decoration:none; } .description2{ background:#f2f2f2; padding:6px; width:60px; text-align:center; border:1px solid #ddd; font-family:Arial; margin-left:750px; margin-top:-30px; font-size:14px; } .description2 a{ color:#555; text-decoration:none; } .yaz{ color:white; } Javascript: // Input name.

  • How can I create an ODBC connection to SAS?

    - by Chris B.
    I'm writing a program that needs to access SAS data. I've downloaded the ODBC drivers for SAS and installed them, but I need to be able to create ODBC connections on the fly, programmatically. The following code (in Python) seems like it should work: import ctypes ODBC_ADD_DSN = 1 def add_dsn(name, driver, **kw): nul, attrib = chr(0), [] kw['DSN'] = name for attr, val in kw.iteritems(): attrib.append('%s=%s' % (attr, val)) return ctypes.windll.ODBCCP32.SQLConfigDataSource(0, ODBC_ADD_DSN, driver, nul.join(attrib)) == 1 print add_dsn('SAS Test', 'SAS', description = 'Testing SAS') But it pops up the SAS ODBC configuration dialog, sets the datasource name, and waits for the user to enter the information and dismiss the dialog. How can I avoid that?

  • How to execute a function until it succeeds?

  • How do you calculate the storage size of a SimpleDB domain?

    - by C. Dragon 76
    The official documentation states: Raw byte size (GB) of all item IDs + 45 bytes per item + Raw byte size (GB) of all attribute names + 45 bytes per attribute name + Raw byte size (GB) of all attribute-value pairs + 45 bytes per attribute-value pair What is the raw size of an attribute-value pair? Is it precisely the size of the value? (I would expect so, but then why is it worded "attribute-value pair"?) Or is it the size of the attribute name plus the size of the attribute value? (In that case, there would be motivation to give your attributes really short names.) For example, what is the size of the tiny domain below? +---------------------------------------------------------+ | Item Name/ID | "Price" attribute | "Calories" attribute | |--------------+-------------------+----------------------| | "apple" | "0000.43" | "0046" | | "orange" | "0000.70" | "0053" | +---------------------------------------------------------+

  • Would this rollback/stop all records from inserting?

    - by chobo2
    Hi I been going through this tutorial http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx and them make a SP like this CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc Now my requirements require me to mass insert and mass update one after another. So first I am wondering can I merge those into one SP? I am not sure how it works with this OPENXML but I would think it would just be making sure that the XPath is right. Next what happens while it would be running this combined SP and something goes wrong. Would it roll back all the records or just stop and the records that happened before this event that crashed it would be inserted?

  • Getting list of fields back from 'use fields' pragma?

    - by makenai
    So I'm familiar with the use fields pragma in Perl that can be used to restrict the fields that are stored in a class: package Fruit; use fields qw( color shape taste ); sub new { my ( $class, $params ) = @_; my $self = fields::new( $class ) unless ref $class; foreach my $name ( keys %$params ) { $self->{ $name } = $params->{ $name }; } return $self; } My question is.. once I've declared the fields at the top, how I can get the list back.. say because I want to generate accessors dynamically? Is keys %FIELDS the only way? Secondarily, is there a more efficient way to pre-populate the fields in the constructor than looping through and assigning each parameter as I am above? Thanks!

  • Send mail to multiple recipient

    - by Ahmad Maslan
    Hi, i have already research on using the mail() to send to multiple recipient's but i just cant get it to work. What im trying to do is, for every order that i have, order 1,2,3, each having their own email addresses, when i change their order status from pending to confirm, the mail() will use that id to refer to the db table and send the email of those 3 orders. But for my case, it mailed just the latest order which is order 3. This is the form that i use to change the order status. <form action="results-action" method="post" enctype="multipart/form-data"> <fieldset> <table id ="table_id" class="display"> <thead> <tr><td><h2>Pending Order</h2></td></tr> <tr> <th scope="col">Order ID</th> <th scope="col"> </th> <th scope="col">Name</th> <th scope="col">Address</th> <th scope="col">Product Name</th> <th scope="col">Produt Quantity</th> <th scope="col">Price</th> <th scope="col">Order status</th> </tr> </thead> <tbody> <?php while ($row = mysqli_fetch_array($result)) { ?> <tr> <td><input type="text" value='<?=$row['virtuemart_order_id']?>' name="orderid" id="virtuemart_order_id"></td> <td><input type="hidden" value='<?=$row['virtuemart_product_id']?>' name="productid" id="virtuemart_product_id"></td> <td><?=$row['first_name']?></td> <td><?=$row['address_1']?></td> <td><?=$row['order_item_name']?></td> <td><?=$row['product_quantity']?></td> <td><?=$row['product_final_price'] ?></td> <td><select name='change[<?=$row['virtuemart_order_id']?>]'> <option value='C'> Confirmed</option> <option value='X'> Cancelled</option></select></td> </tr> <?php } ?> </tbody> </table> </fieldset> <fieldset> <table> <tr> <td><input type="submit" value="Update status" name="update status"> </td> </tr> </table> </fieldset> </form> This is the php, using the order id from the form to select the email addresses. <?php $orderid = $_POST['orderid']; // build SQL statement to select email addresses $query3 = "SELECT email from ruj3d_virtuemart_order_userinfos where virtuemart_order_id = '$orderid'"; // execute SQL statement $result3 = mysqli_query($link, $query3) or die(mysqli_error($link)); $subject = "Order confirmed by Home and decor"; $message = "Hello!

  • Composite primary keys in N-M relation or not?

    - by BerggreenDK
    Lets say we have 3 tables (actually I have 2 at the moment, but this example might illustrate the thought better): [Person] ID: int, primary key Name: nvarchar(xx) [Group] ID: int, primary key Name: nvarchar(xx) [Role] ID: int, primary key Name: nvarchar(xx) [PersonGroupRole] Person_ID: int, PRIMARY COMPOSITE OR NOT? Group_ID: int, PRIMARY COMPOSITE OR NOT? Role_ID: int, PRIMARY COMPOSITE OR NOT? Should any of the 3 ID's in the relation PersonGroupRole be marked as PRIMARY key or should they all 3 be combined into one composite?? whats the real benefit of doing it or not? I can join anyways as far as I know, so Person JOIN PersonGroupRole JOIN Group gives me which persons are in which Groups etc. I will be using LINQ/C#/.NET on top of SQL-express and SQL-server, so if there is any reasons regarding language/SQL that might make the choice more clear, thats the platform I ask about. Looking forward to see what answers pops up, as I have thought of these primary keys/indexes many times when making combined ones.

  • console.log() and google chrome

    - by Lorenzo C
    I'm testing a library and I use console.log() function to visualyze values. There is a strange behaviour of Google Chrome (in other browser like Firefox it doesn't happend). If I try to store strings in Array object when I log them, sometimes values appears undefined. Code example (item.name is a string) var arrayItemsSearch = [item.name]; var itemRedrawName = [item.name]; console.log("arrayItemsSearch: ", arrayItemsSearch); console.log("itemRedrawName: ", itemRedrawName); Firefox output is correct arrayItemsSearch: ["elem[0]"] itemRedrawName: ["elem[0]"] Chrome output is not correct arrayItemsSearch: [undefined × 1] itemRedrawName: ["elem[0]"] Is this a Chrome bug? Or is this beacuse in Javascript strings are immutable objects and so something that I don't understand goes wrong?

When you click the Update Cart button it just updates the cart page it's on, but when you click the Shop More button it links to Shop.aspx a different page, and the Checkout links to another page as well. I can't figure out how it is linking just from that code, anybody have any insights?

  • FreeText Query is slow - includes TOP and Order By

    - by Eric P
    The Product table has 700K records in it. The query: SELECT TOP 1 ID, Name FROM Product WHERE contains(Name, '"White Dress"') ORDER BY DateMadeNew desc takes about 1 minute to run. There is an non-clustered index on DateMadeNew and FreeText index on Name. If I remove TOP 1 or Order By - it takes less then 1 second to run. Here is the link to execution plan. http://screencast.com/t/ZDczMzg5N Looks like FullTextMatch has over 400K executions. Why is this happening? How can it be made faster?

  • Psycopg2 doesn't like table names that start with a lower case letter

    - by Count Boxer
    I am running ActiveState's ActivePython 2.6.5.12 and PostgreSQL 9.0 Beta 1 under Windows XP. If I create a table with an upper case first letter (i.e. Books), psycopg2 returns the "Programming Error: relation "books" does not exist" error message when I run the select statement: execute("SELECT * FROM Books"). The same error is returned if I run: execute("SELECT * FROM books"). However, if I change the table to a lower case first name (i.e. books), then either of the above statements works. Are tables name supposed to have a lower case first name? Is this a setting or a feature or a bug? Am I missing something obvious?

  • JS Variable inside another variable

    - by Tusk
    I have a function that would use other variables, depending on what has been passed. Like this = ActionBar(slot) slot contains "one". and I would like to create a call inside that like object.slot.name but it should convert it before hand to make the command look like object.one.name. Is there a way to do this in javascript/jquery? I remember vaguely that some other language does this as {slot} or something like that. Sorry if this question was already asked, I've checked google and stackoverflow too, but didn't find an answer. Also I'd like to know what's the proper programming term for this kind of variable passing? Edited it cause of misunderstandings. I'm looking into OOP js, so object is an object, one is an object, and name is an attribute, but when passing I'm passing "one" as a string to the function. Tried eval, it doesn't work while dotted with an object.
