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

I am trying to write a page to read the Excel file provided by the user. I know I can't use the FileUpload to get the full path of the file from the client PC. This give me the problem when I write the connection string for the Excel file:
[Code]....
Without the full path, I can't replace the Data Source by a variable and I definitely can't assume all users will have their Excel files named Book1.xls located in C:Doc all the time.
I have this code
Dim myDataset As New DataSet()
Dim strConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & Request.ServerVariables("APPL_PHYSICAL_PATH") & "dynamicuploadedLists" & strFileName & ";" & _
"Extended Properties=""text;HDR=Yes;FMT=Delimited(,)"";"
''You must use the $ after the object you reference in the spreadsheet
Dim myData As New OleDbDataAdapter("SELECT * FROM [" & table & "$]", strConn)
'myData.TableMappings.Add("Table", "ExcelTest")
myData.Fill(myDataset)
And I am getting the error , while the path is correct.
'E:missitenamedynamicuploadedListsSheet1.csv' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.
I have been able to import an excel file sql bulkcopy locally. But when I publish the code to the server I get the following error messages:
Exception Message: 'C:MyTest.xls' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.

I've got a simple (inline) ASPX page that is ouputting XML.
I want to import this XML into Excel 2007 using Data | From Other Sources | From XML Data Import.
If I specify the URL for my APSX page Excel opens the result into the Text Import Wizard :(
If I open my URL directly from Notepad, save the content to a file and import that into Excel, its correctly treating is a Xml. why Excel is treating the result as text when is comes from a Url?
Heres the code from the ASPX Page
<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<%@ Import Namespace="System.Xml" %>

Is there some simple way I am missing to import an Excel worksheet into a datatable using an OleDBConnection and change what row the header is located on? I have HDR=YES in my connection string and that works great when header is on row 1 but the header is actually going to need to be on row 3. I am using the following CommandText:
SELECT [headercol1name], [headercol2name], [headercol3name] FROM [sheetname]
I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data.
I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db. My question is what can anyone give me code to open an excel file, know what line the data starts on in the file, and import the data into a datable object?
Is there a way wherein I could import data from multiple sheets of an excel file?

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'm attempting to import, using VB.Net, a spreadsheet from some other users than myself. In the spreadsheet with headers, the numbers I'm importing are in the first column of the spreadsheet (Excel 2003 to 2007). I've defined my datacolumn for the column with the numbers as a "string". What's happening is the trailing zero is dropped; so 1.1 and 1.10 both appear as => 1.1.My code is attatched below.I know I'm missing something, I just don't see it!I've tried both; MicroSoft.JET.OleDb.4.0 and MicroSoft.ACE.OLEDB.12.0 but neither seems to make a difference.

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.
