DataSource Controls :: Importing Excel File AND INSERT It Into SQL?
May 19, 2010
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
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.
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).
The Microsoft Jet database engine could not find the object 'MyDataFile$'. Make sure the object exists and that you spell its name and the path name correctly.
below is my code, i am exporting my excel sheet in HTML format. in case of importing i am facing the above mentioned error.
I facing a problem when I upload a file from my side while the application is running in server.
The error shows below:
'C:Excel FilesStaff Directory1.xlsx' 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 am importing a comma seperated, single quote delimited file based off of client specifications. The only problem is now the client is sending apostophes in the file and is throwing off the single quote delimiter.
For Example:
'FirstName','LastName' 'John','O'Grady'
I need to figure out somehow to escape or replace that character before it goes into my OLE dataset import and then handle it before it hits my SQL table. Here is my current process flow:
Save the file to the App_Data using a FileUpload control Build a schema.ini for the ' delimeter Import into a dataset using Microsoft Jet OLE Use a for loop to pick out the fields that I need and build an insert into SQL I was trying to replace the ' with an underscore but then ended up replacing the whole file instead of just the one in the name.
I want to read date field from Excel sheet and insert it into SQL Server2005.When I read date field it gives me a number say '40160' when the date feild is "08/01/2010"
How should to Read a date field from Excel Sheet Cells?
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?
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 a page where users can upload an excel file and it is read into our system. I am using the Jet.OLEDB.4.0 provider to read the files. I access the file one time to read out the header names and then allow the user to select which field each column will be read into on import. For some reason after this read the file is locked and the next time I try to access it to do the data import I get the "File in use" message. Each time I open a connection it is closed so I am not sure why the file is being locked.
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?
I need a way to read all the rows in one column from an Excel file that the user picks from a fileupload control. I tried saving the excel file on the webserver with the upload control and then opening it with a OleDbConnection but that fails when running it from the webserver and gives the error:
Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
This works fine when just running it localhost, so i figured it might be a problem with security level at the webserver which i cant change. Instead i tried doing it with a streamreader direct from the fileupload control and because theres no need for saving the excel file on the server, but im not sure how to query the rows i need this way.
I want to insert data in sql server from sheet within excelsheet ,there are three sheets in the file which i want to upload in three different tables,currently i am doing by selecting an individual sheet and the table to upload thus doing it three times for three sheets can i do it in one go,like passing all the sheets to a function or something like that or how can i do it in a better way and also i cannot directly upload sheet into table as i have to map one column of excel to different table of database to get its value like i need statecode but statename is provided in the sheet so i map statecode to statename in a staging table and then i upload the data...
i am following article in aspsnippets to upload excel file ,it is working fine for 2007 format of excel but displaying error "External table is not in the expected format." for 2003 format

While I am trying import by clicking on Import only the datas in the CurrentPage is getting exported and remaining datas are not..I mean ..If my GridView shows 50 records at a time only these records are getting imported and remaning records are not
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.
