SQL Server :: Retrieving The Single Record With The Most Recent Datetime?
Oct 18, 2010
In the stord procedure below. I am retreiving all the records for that 1 deal. What I want is to retrieve the most recent record hence the one with the most recent in the AddedDate field.
How can I accomplish this?
(
@DealID int)
AS
SET NOCOUNT ON
SELECT deals_Comments.CommentID, deals_Comments.AddedDate, deals_Comments.UserID, deals_Comments.AddedByEmail, deals_Comments.AddedByIP, deals_Comments.DealID, deals_Comments.Body, deals_Comments.SBody,
ROW_NUMBER() OVER (ORDER BY deals_Comments.AddedDate DESC) AS RowNum
FROM deals_Comments
WHERE deals_Comments.DealID = @DealID
I am wanting to insert a record into a table in SQL then retrieve its key at the same time, the key is a int that is automatically generated, I read something about the '@@Identity' function, is this what I need? How could I then bind this to a label in the ASP.net page?
Last night I started working on an NHibernate provider. I'm creating a criteria that several records will match, however I only want to return the most recent record (the record with the largest Id). I thought UniqueResult() would do this it cannot be used if a list would be returned otherwise.
I could theoretically select the full list and then return the desired record, but I believe there is a better way.
I'm having a question about retrieving data. I'm using VS 2008 and I have to create a new consultation record for a patient and I've already created a database with 3 tables, which are doctor, patient and consultation.
I have 10 records saved in consultation table, and I've made a aspx form which contains a DetailsView that ask for new consultation details to be added. But I have to be able to get the doctor and patient information from the database and put in the DetailsView, then fill in the rest of the consultation details. The information entered have to be written to the database in the consultation table. But I don't know how to get doctor and patient information from database and apply them into the DetailsView so that doctor who wants to add new consultation details can select patient and doctor information from the database.
I was thinking maybe I need to do a query with insert statement and apply into the DetailView,this is the query i have:
I have a drop down which gets data from database.I want to show not all entries but the very last one entered by employee. What do I have to add to the sql script to get me very last entry and hide the rest.this is my Sql data source:
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CompanyInfoEventsConnectionString %>" SelectCommand="SELECT [ID], [NameOne] FROM [Gpi_DayOff] ORDER BY [ID] DESC"> </asp:SqlDataSource>

On UI Ajax calendar control is used to allow the user Expiry Date as shown below. As this is one of the controls in search, when the Search button is pressed using SQL statement (copied below) data is retrieved from ExpiryDate column of the table. The table creator declared the column type as string and the dates are saved as single digits(Example: 2/2/10 sometimes and sometime as double digits (Example: 02/02/10) I like to know the best practice in retrieving both type of strings from database table. Calendar control

I am trying to store a SQL Server datetime into MySQL datetime field, but MySQL stores the date value as all zeros. I use this function to trim the fractional part from the SQL Server datetime, but get the same result when trying to store it in MySQL.
Over the last couple of weeks, i've been playing around with expression web to try and update our current company website: [URL]
Basically, our site is quite simple. We have individual product categories that are displayed and then the user can click through to view the individual product specification and pictures of said product.
I've created the category pages and inserted hyperlink fields to link to the individual product pages which works fine.
The problem i'm having is getting the specification and pictures to display on the product pages.
I'm literally tearing my hair out as i'm quite new to this.
The access database i'm using has the following fields, ProductID, CategoryID, Description, Comments (This is the Specification field) and then Image1, Image2, Image3 etc all the way up to image 10.
What i've been trying to do is to use an imagefield within a gridview to pull the Image name from the image fields and then display said images from the images folder. I have got this to work of a fashion, yet all the images are displaying instead of the particular product images only. I believe i need to add a query string to do this yet i'm totally at a loss as to how to set this up...
I'm also having the same problem with the specification (comments field) as i can't figure out how to only display the individual product spec..
I'm using a datalist that uses an item template to display results from an objectdatasource. The thing is, I'm only fetching a single record so a datalist doesn't seem like the best option. Is there a more suitable control I can use?
Also, how do I access the data on an objectdatasource that has been created in design view from code-behind. I've tried google but with no success.

've got a slightly odd requirement that I'm not sure how to properly articulate.I essentially want to prioritise the most recent requests to an ASP.Net handler. I'm not sure if this should be client-side or server-side. I'm leaning towards server side to ensure it's enforced on all clients.So, as requests come in, they're essentially stacked according to some internally-defined time interval, per client. Then, the top of the stack (most recent) request is processed first.
