  • Why can't I pass in a uniqueidentifier/GUID to a stored procedure

    - by chobo2
    Hi I have this SP USE [TestDB] GO /****** Object: StoredProcedure [dbo].[sp_test] Script Date: 06/12/2010 11:47:27 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[sp_test] @id uniqueidentifier AS BEGIN select * from TestTbl where ProductId= @id END I then went to the SP with ms sql 2005 and clicked execute. It comes up with a box where I entered in the GUID. I copied and pasted it straight from my test database. I get this error. Msg 102, Level 15, State 1, Line 5 Incorrect syntax near 'cac671b'. So why can't I sent in GUIDs? even ones that are copied right from the database and must be valid as they where allowed into the db.

  • mysqli::query returns true on SELECT statement

    - by Travis Pessetto
    I have an application that reads in one of its classes: public function __construct() { global $config; //Establish a connection to the database and get results set $this->db = new Database("localhost",$config["dbuser"],$config["dbpass"],"student"); $this->records = $this->db->query("SELECT * FROM major") or die("ERROR: ".$this->db->error); echo "<pre>".var_dump($this->records)."</pre>"; } My problem is that var_dump shows that $this->records is a boolean. I've read the documentation and see that the SELECT query should return a result set. This is the only query used by the application. Any ideas where I am going wrong?

  • Entering Complex Data into Access

    - by DataMakesMeCrazy
    Fairly new to Access and trying to do something that seems simple, but may be very complex. I want to create a database of projects, each project has several phases (ie proposal, marketing, etc) and that will allow for multiple employees to work on a single project. Ie Bob and John are working on project number 102. From here, i would like to enter the forecasted start and end dates for each phase of the project, and enter the forecasted number our hours each employee will be allowed to work on that phase of that project ie. Project - Employee - Phase - Start - End - (list weeks) 102 - Bob - Marketing - 12-May-10 - 21-May-10 - 3 - 5 (3 hours first week, 5 hours the second) and so on Basically would all this data be on one table, or several? And can access dynamically show the weeks between the start and end date so that i can input the hours? I feel this database will become severely complicated :S Thanks, J

  • How to make a particular information to be accessible at masterpage, page and usercontrol

    - by Ismail S
    I'm fetching some settings out of the database based on a value passed from a query string. Out of these settings, a few will be used in master page, few on my Page and few in my user control (say login control which is a web user control). I've an entity class MySetting for it and there is a method in my data access layer which returns me an instance of MySetting when I pass the value I got in query string. I don't want to fetch settings from the database multiple times for one request. I'm using asp.net web forms with C# and sql server.

  • Sticky notes associated with web page - how to?

    - by volvox
    I have this idea for a project. Associated with any web page, i want to create notes that will be saved locally in a database, the notes will be reloaded automatically from that database the next time i visit the same page. Creating the note is easy, but i'm looking for how to link the notes to the web page url and how to keep aware of the active web page. Any idea? (Note: i have come to this searching on the internet: http://webkit.org/demos/sticky-notes/ - this is part of WebKit Open source projects) - this is about what i'm looking for. Thank.

  • Uploading a Website

    - by 01010011
    Hi, This is my first time building a website and using CodeIgniter for a school project. I was wondering whether you have any tips on uploading CI to a free web host , my database, free webhosting and basic security tips. Can I just upload the entire CI folder? Or do I have to upload individual files (God no!)? What are my options? What about my MySQL database - do I just upload my mysqldump to the webhost? Also, can you recommend a good free webhost. I was thinking about 000webhost. Any basic tips on security would also be appreciated (I've implemented many of the form_validation rules like xss_clean for starters) Any other suggestions will be more than welcome. Thanks!

  • Jsp cache problem

    - by idiotgenius
    I use javascript and css to build a multi-level drop down menu with following markups: <ul> <li>menu item 1</li> <ul> <li><a href="#">sub menu menu item 1</a></li> ................. This markup is generated by a custom JSTL tag <mui:menu .../> which loads menu data from a database. I hope my jsp page can behave like this: if menu data has not changed since last time I visited the page, just use browser's cache otherwise load from database... How can I do it? I don't know much detail about cache mechanism.

  • Server.Transfer - What could be the issue here?

    - by Younes
    We have implemented a website with the ability for the user to post his actioncode. This then will be checked by the code and when the user has a price the website will Server.Transfer him to another page. The strange thing here is that the user information will be submitted to the database and the actioncode can't be used again. Here we go... I have one user in this database that is inserted twice very fast after the first time he was added. This are the timestamps: 2010-04-23 07:54:41.133 2010-04-23 07:54:41.417 The insert statement is only called once from the code and the user gets Server.Transfered to the Price.aspx page where he sees what price he won. How can it be that this happened? I'm guessing the user hitted F5 but then he had to be very very fast... Thx!

  • Many-to-one relation exception due to closed session after loading

    - by Nick Thissen
    Hi, I am using NHibernate (version 1.2.1) for the first time so I wrote a simple test application (an ASP.NET project) that uses it. In my database I have two tables: Persons and Categories. Each person gets one category, seems easy enough. | Persons | | Categories | |--------------| |--------------| | Id (PK) | | Id (PK) | | Firstname | | CategoryName | | Lastname | | CreatedTime | | CategoryId | | UpdatedTime | | CreatedTime | | Deleted | | UpdatedTime | | Deleted | The Id, CreatedTime, UpdatedTime and Deleted attributes are a convention I use in all my tables, so I have tried to bring this fact into an additional abstraction layer. I have a project DatabaseFramework which has three important classes: Entity: an abstract class that defines these four properties. All 'entity objects' (in this case Person and Category) must inherit Entity. IEntityManager: a generic interface (type parameter as Entity) that defines methods like Load, Insert, Update, etc. NHibernateEntityManager: an implementation of this interface using NHibernate to do the loading, saving, etc. Now, the Person and Category classes are straightforward, they just define the attributes of the tables of course (keeping in mind that four of them are in the base Entity class). Since the Persons table is related to the Categories table via the CategoryId attribute, the Person class has a Category property that holds the related category. However, in my webpage, I will also need the name of this category (CategoryName), for databinding purposes for example. So I created an additional property CategoryName that returns the CategoryName property of the current Category property, or an empty string if the Category is null: Namespace Database Public Class Person Inherits DatabaseFramework.Entity Public Overridable Property Firstname As String Public Overridable Property Lastname As String Public Overridable Property Category As Category Public Overridable ReadOnly Property CategoryName As String Get Return If(Me.Category Is Nothing, _ String.Empty, _ Me.Category.CategoryName) End Get End Property End Class End Namespace I am mapping the Person class using this mapping file. The many-to-one relation was suggested by Yads in another thread: <id name="Id" column="Id" type="int" unsaved-value="0"> <generator class="identity" /> </id> <property name="CreatedTime" type="DateTime" not-null="true" /> <property name="UpdatedTime" type="DateTime" not-null="true" /> <property name="Deleted" type="Boolean" not-null="true" /> <property name="Firstname" type="String" /> <property name="Lastname" type="String" /> <many-to-one name="Category" column="CategoryId" class="NHibernateWebTest.Database.Category, NHibernateWebTest" /> (I can't get it to show the root node, this forum hides it, I don't know how to escape the html-like tags...) The final important detail is the Load method of the NHibernateEntityManager implementation. (This is in C# as it's in a different project, sorry about that). I simply open a new ISession (ISessionFactory.OpenSession) in the GetSession method and then use that to fill an EntityCollection(Of TEntity) which is just a collection inheriting System.Collections.ObjectModel.Collection(Of T). public virtual EntityCollection< TEntity Load() { using (ISession session = this.GetSession()) { var entities = session .CreateCriteria(typeof (TEntity)) .Add(Expression.Eq("Deleted", false)) .List< TEntity (); return new EntityCollection< TEntity (entities); } } (Again, I can't get it to format the code correctly, it hides the generic type parameters, probably because it reads the angled symbols as a HTML tag..? If you know how to let me do that, let me know!) Now, the idea of this Load method is that I get a fully functional collection of Persons, all their properties set to the correct values (including the Category property, and thus, the CategoryName property should return the correct name). However, it seems that is not the case. When I try to data-bind the result of this Load method to a GridView in ASP.NET, it tells me this: Property accessor 'CategoryName' on object 'NHibernateWebTest.Database.Person' threw the following exception:'Could not initialize proxy - the owning Session was closed.' The exception occurs on the DataBind method call here: public virtual void LoadGrid() { if (this.Grid == null) return; this.Grid.DataSource = this.Manager.Load(); this.Grid.DataBind(); } Well, of course the session is closed, I closed it via the using block. Isn't that the correct approach, should I keep the session open? And for how long? Can I close it after the DataBind method has been run? In each case, I'd really like my Load method to just return a functional collection of items. It seems to me that it is now only getting the Category when it is required (eg, when the GridView wants to read the CategoryName, which wants to read the Category property), but at that time the session is closed. Is that reasoning correct? How do I stop this behavior? Or shouldn't I? And what should I do otherwise? Thanks!

  • Character encoding issues in MySQL

    - by Eric
    In my database we have fields where the data is not readable. I now know why it happened but I don't know how to fix it. I found a way to get the info back from the database: SELECT id, name FROM projects WHERE LENGTH(name) != CHAR_LENGTH(name); One of the rows returned shows: id | name ------------------------- 1008 | Cajón el Diablo This should be: id | name ------------------------- 1008 | Cajón el Diablo Can somebody help me figure out how to fix this problem? How can I convert this using SQL? Is SQL not good? If not, how about Python?

  • Filemaker XSL 20sec Query Latency

    - by Ian Wetherbee
    I have an ASP frontend that loads data from a Filemaker database using XSL to perform simple queries. The problem is that the first page load takes 20 seconds +/- 200ms, then the next few page refreshes within a minute of the first request take <200ms, then the cycle starts over again. Each page load makes only 2 XSL queries, and they execute fast after the first page load, so what is causing the delay on the first page load? I have caching turned up with a 100% hit rate, and number of connections at 100. I've tried with XSL database sessions on and off, and session time anywhere from 1 to 60 minutes without any changes. The XSL loads from ASP use a GET request and add a Basic Authorization header to authenticate each time. During fast page requests, the fmserver.exe and fmswpc.exe processes don't even flinch, but during a 20 second holdup I see fmserver jump to 30% CPU and a 3mb I/O read a few seconds into the request, and occasionally fmswpc jump to 60% CPU.

  • Elegant solution for multiple forms on single page

    - by NFicano
    I'm building a web application (in Django) that will accept a search criteria and display a report - once the user is satisfied with the results, save both the criteria and a reference to these objects back to the database. The problem I'm having is finding an elegant solution for having 2 forms: Display (GET) the results of their criteria. Enter in some descriptions, and save (POST) everything back to the database. I'm leaning towards AJAX for the GET stuff and a POST for the save, but I wanted to make sure there wasn't a more elegant solution first.

  • Fluent NHibernate CheckProperty and Dates

    - by Chris C
    I setup a NUnit test as such: new PersistenceSpecification<MyTable>(_session) .CheckProperty(c => c.ActionDate, DateTime.Now); When I run the test via NUnit I get the following error: SomeNamespace.MapTest: System.ApplicationException : Expected '2/23/2010 11:08:38 AM' but got '2/23/2010 11:08:38 AM' for Property 'ActionDate' The ActionDate field is a datetime field in a SQL 2008 database. I use Auto Mapping and declare the ActionDate as a DateTime property in C#. If I change the test to use DateTime.Today the tests pass. My question is why is the test failing with DateTime.Now? Is NHibernate losing some precision when saving the date to the database and if so how do prevent the lose? Thank you.

  • sql: DELETE + INSERT vs UPDATE + INSERT

    - by user93422
    A similar question has been asked, but since it always depends, I'm asking for my specific situation separately. I have a web-site page that shows some data that comes from a database, and to generate the data from that database I have to do some fairly complex multiple joins queries. The data is being updated once a day (nightly). I would like to pre-generate the data for the said view to speed up the page access. For that I am creating a table that contains exact data I need. Question: for my situation, is it reasonable to do complete table wipe followed by insert? or should I do update,insert? SQL wise seems like DELETE + INSERT will be easier (it is single SQL expression). EDIT: RDBMS: MS SQL Server 2008 Ent
