DataSource Controls :: Identifying Duplicates In Data Upload?
Mar 3, 2011
Using SQL server and C# to build my web site. I need to do a bulk upload Employee data from Excel to SQL.
I use the following code to perform this. The code works fine.
[Code]....
In the Employee table there is a field called ID which is of type int and auto incrememntral . This is the primary key.
There cannot be duplicates in the combination of EmployeeName and Location. If the user tries to upload ( through the Excel file) the combination of EmployeeName and Location which is there in the database, I need to flag it.
How can I identify the duplicates in an easy way rather than going through all the records again and again? Any functaion in SQL I can use to identify the duplicates?
I have a table named dups. There are 4 columns in the table.
id, name, path, hash
I want to return only the name, path, hash of each row where the hash field is the same. Example there are 100 rows but only two qualify the return would be.
file1 c: 10909 file4 d: 10909
For some reason this seems to be a more difficult task than I though it would be.
I have location #s, date, time, the sales amount, and tax in a excel file. The system pulls sales numbers throughout the day from each store location and places the total sales and tax numbers along with the polling date into a file.
So the most current date/time has the most upto date sales numbers at the time for that location number, but it also lists the older entries so mgmt can see how sales went during the day, and this is where my issue is, I don't need to see the old numbers from this generated file (atleast at this part of the program).
What I would like to do is write a query that only selects the most recent sales numbers for each location. I will output this to a table in ASP.NET. The query I tried using the TOP 1 clause only gave me the very first row listed below.
I am developing web application using Csharp on Visual studio 2008.How can I avoid duplicates on a data grid? I am using one form with datagrid. When I run it while it is in one of the folders AB it is running without any problems and data grid is displaying correct records. However, when I get the same and put it on a different Folder AB1 on the same machine and web server (IIS) it is displaying duplicated records?
I have a gridview that I loop through to get the x and y values of the chart control, and upon the first execution of this code, it looks great. But when the page posts back and it "refreshes" data, the original points on the chart control are still there, as well as the new values.
Is there any way to "delete" all data in the chart control to ensure this doesn't happen?
I have query that returns a line that looks like this belowA NEWYORK PROGRAM AA NEWYORK PROGRAM Bnow, the NEWYORK is inputted into a dropdownlist and the program A and program B is inputted into a dropdownlist as wellI am using utility.ControlTools.SetListControl for my dropdownlist. I would like a situation where my dropdownlist only contains one NEWYORK instead of two and my dropdownlist for programs to contain Program A and program B. Can this be done.
i have an aspx page which has a fileuploader and a button
initially i have to browse the file and after browsing the file i have to check the extension if the extension is xsl or xslx then only i have to enable the submit button
once the submit button is enabled i have to insert this data into the table
and i have to display the number of succesfully inserted rows and no of unsuccessfull insertions .
success and failure is dependent on the mismatch of the datatype between the excel sheet and the database column
I have several LINQ-auto-created data classes which are created using dragging and dropping database tables into the Visual Studio LINQ design pane. Also, in my project I have to manually create WCF data-contract classes. Each WCF contract class is for one LINQ-auto-created data classes; one to one. Is there some better way to reduce the efforts to this problem? e.g. inheritance or something else to create WCF datacontract class from existing LINQ-data class.
Say I have a single page/form with a search facility (i.e. a textbox plus 'Go' button) and a login facility (username, password and 'Login' button).
Is it possible to identify within the Page_Load event which button the user has clicked - i.e. 'Go' or 'Login' - can I somehow use the 'Source' and/or 'e' parameters to identify this?
I can direct both buttons to different OnClick event handlers or direct both to the same handler and identify the button using the Id or text properties but I'm curious to know whether the button can be identified at the Load stage.
Let us assume the following relationships (diagram). A FundCompany has Funds, and Accounts. There is also a FundAccount which creates a many-to-many relationship (as well as other attributes at the relationship level) between Accounts and Funds. Lastly an Account has one or more Beneficiary.The FundCompany is an aggregate root as it's at the top of the pyramid. Neither Account nor Fund can exist without the FundCompany. FundAccount cannot exist without both Fund and Account; does that make them both aggregate roots? Or is Fund still the only aggregate root, having to go through it to perform operations on FundAccount entities? The fact that the Account also has Beneficiaries, which cannot exist without the Account, does that also signal Account being an aggregate root?
All of the entities on this diagram will require CRUD operations and screens in my application. The reason I'm bringing this is up is most often every UI screen will store the ID of the row/entity it's referencing. So for example a user clicks "Details" on a table with Funds, I might need to retrieve a fund via its ID. My understanding is that if an entity needs direct access then it's an aggregate root in itself. However this would make a lot of entities aggregate roots by default.Based on the answers to above questions I have to map these operations to the proper aggregate root's repository.
In my database table i have coulmn with image data type.what should i put there? location of the image ? how do i retrieve the image later? as usual other data type?
I'm using Visual Web Developer 2008 Express Edition, coding in C#. I think that the framework that I am aiming for is 2.0.
I am working on some old projects here where I work. However, I do not have access, nor do I know what the original programmer used to write this code.
The following code gives me an error:
[Code]....
(note that SlideList is an ArrayList that is being assigned to a DataSource. Also, this code is found inside a function named "CreateFeaturedSlideShow", which is called by the function "Page_Load" in "default.aspx.cs")
When I try to compile the project I get this error code: "The type or namespace name 'slideShow' could not be found (are you missing a using directive or an assembly reference?)"
When I comment out the code, the project compiles. However, when I try to run it, I get another error message: "Only one of AdvertisementFile, DataSource, or DataSourceID properties can be set on AdRotator 'AdRotator1'. "
From examing the rest of the code, it seems like this part of the project is populating a database with advertisement data, and selecting an ad at random, and keeping track of various statistics.
My problem is that I am having difficulty locating anything that will give me a slideShow namespace. The top result seems to be the SlideShow Extender, but after adding this toolkit to my toolbox nothing changed, which leads me to believe that I have something else.
Does anybody know where I can find this 'slideShow' that is referred to in the code?
I am writing code to insert values from an xml file. I check for a duplicate before inserting and delete if there is a match. Is there a more effecient way to prevent duplicates before insert a record? my code: private void LoadFData() { SqlConnection oConn = new SqlConnection(ConnectionString); SqlCommand oCommand = new SqlCommand(); oCommand.Connection = oConn; oCommand.CommandType = CommandType.Text; oConn.Open(); // Load committee master files string[] strFiles = System.IO.Directory.GetFiles("fff", "ffff.dta", System.IO.SearchOption.AllDirectories); for (int i=0; i
CREATE TABLE [dbo].[tblChildTest]( [ChildID] [int] IDENTITY(1,1) NOT NULL, [DOB] [datetime] NOT NULL, [AdmissionNo] [nvarchar](100) COLLATE Latin1_General_CI_AS NULL, [FirstName] [nvarchar](100) COLLATE Latin1_General_CI_AS NOT NULL, [LastName] [nvarchar](100) COLLATE Latin1_General_CI_AS NOT NULL, [Imported] [tinyint] NULL ) ON [PRIMARY]
I want upload csv file data using sql bulk upload . ChildID is autonumber , so i want start data upload from second column. i want omit childid and start from DOB.
