importing excel/spreadsheet into sql server using C#? Whenever I run the webpage by selecting excel file, first it will empty sql server table then import data from excel.
View 3 RepliesI have a requirement that the user will need to import a list of ID's to the asp.net website from their own spreadsheet. I will provide a button 'btnImport' which will use an OleDbConnection to read the spreadsheet and pull in the id's. I have that working fine in my local dev environment. My question is, when this app is running on a production server, will the user have to upload her spreadsheet to the server first? Or do I need to provide code that will find the file on her machine? I'm not sure how this part of it works.
View 4 Replies from an Access database, I created an Excel spreadsheet. On the spreadsheet I made the adjustments I needed to and then proceeded to use the SQL Server 2005 Import/Export Wizard to import the spreadsheet into a SQL table. I then get the following error message:[Code]....
When I remove the problem columns from the import, then it works just fine. But I really need those text columns! The SQL Server columns that they are supposed to go into are varchar(MAX).
this is me once again moving around data access. my problem now hide in the import process of an excel file that would be inserted into sql db.
the problem is the excel file may be updated or changed and i have to periodically import it and perform the process but I still cant check or compare between the two Data Source (excel, sql) as I violate the entity integrity (PK)
i found a kind of stupid approach that each time i want to import the file i will empty the table then re-insert the data, but at this step a new problem raise that other tables are !engaged! with it ... so i will violate the referential integrity (FK)
i looking for solution to compare between two sources for each tuple / row, ignore the existing one and insert the new

View 2 RepliesI'm trying to upload an excel spreadsheet using the FileUpload control, read the excel sheet using OleDb connection, and save the strings onto a sql server database.Then, I'm trying to read each string in another method.My web app is currently hosted on the network on my local box, and using savePath= @"C:desktop" like I had it previously wasn't working, so I figured using a sql server database would work for being able to save the file and open it again... but I'm getting confused on how to do so, so i tried using my old savePath but it's not working anymore. So... I'm really at a lost on what to do and how to fix it.

I simply have a lot of data in two columns in an excel spreadsheet of data that I gathered. I want to copy and paste this (manually) into a table that I have created in my ASPNETDB in my ASP.NET web application. I thought it'd be as easy as copy the column, and hit paste in the "table data" view, but it's not (it only pastes one cell).
Is there a way for me to manually copy data from excel and paste it in a table in my SQL Server?
I have a table with 100 records. I need to import extra 50 records in the same table. So from 101 to 150 records should insert the data which is present in excel Simply I want to import 50 records from Excel to Table without disturbing the first 100 records.
View 5 RepliesI got an excel spreadsheet (will have tons eventually) that have "Start Date" and "End Date" columns, with a format of "dd/mm/yyyy".For time being, I just want to import these to a temporary table in my database, and use the SQL Server Import/Export wizards.
Now this wizard import the the above fields as nvarchar, instead of date or datetime (not sure which would be better?).I tried to convert the columns to datetime after importing, but this is not allowed (Saving changes is not permitted. The changes you made require that the following tables to be dropped and re-created, ......).
So I deleted the temporary table, and ran the wizard again, this time trying to edit the mappings and specify the two fields to be date times, but this also fails.I also fiddled around with convert and cast, but always end up getting "Conversion failed when converting date and/or time from character string." errors.
I looked myself skew, and are pretty sure all the fields in the excel sheet do have values, and are in the "dd/mm/yyyy" format.(I've been absent from SQL for a long long time!)

I have some code that generates a zip file that contains multiple CSV files and streams it back to the user (no file is saved on the server). However, I want to create an excel workbook instead (can be traditional xls or Office Open XML xlsx format) with each CSV 'file' being a spreadsheet.
How can I do this, without resorting to Office Automation on the server or a commercial 3rd party component?

View 2 RepliesOn an .aspx page in a web site I need to retrieve some data from a sql server database and, instead of displaying it in a Gridview, I need to put the data in a spreadsheet and present the user with a Save As dialog.
I'd prefer to do it without using the Office / Excel / Interop com object - so, from what I've read so far, I can do this by returning XML data from SQL Server?
Normally I get data from SQL Server and populate a dataset or datareader with it - and then use this as the Datasource of a GridView.
If I run this in SQL Server ...
Code:
SELECT UserID, UserName FROM tblUsers FOR XML Auto, Root('Users')
It produces this ...
Code:
<Users>
<tblUsers UserID="1" UserName="Steve" />
<tblUsers UserID="2" UserName="Andrea" />
<tblUsers UserID="3" UserName="Zebedee" />
</Users>
So, first question - how do I get the data from SQL Server into my .aspx page? (All data access is done with stored procedures - so, from my data access class normally I create, for example, a SQLDataReader and populate it by calling a stored procedure. What object would I populate with the results of a stored procedure that contains a select statement with 'FOR XML Auto'
Then, assuming I get the XML into the .aspx page - how do I get it into a spreadsheet so that there are two columns called UserID and UserName and 3 rows with 1, 2 and 3 in the first cell and Steve, Andrea and Zebedee in teh second cell?
