I have been facing a problem since last two days, actually i want to import some data from a file (file can be csv, txt, sql, xls etc) and after some filtration, export it into csv file. Basically i want to know whether a tool which provides an environment to import different types of file or data where we can perform filtration of data with sql query and then data could be save into file(file can be csv, txt, sql, xls etc)
Some time back i posted for help in uploading CSV file to DB. With the assistance of other members, i was able to set that up on a test page and got the functionality working.. Now project is coming to the end and need to take that code / logic and incorporate with our application. On certain forms, we need to allow the user to export / import via a CSV file.. So this question is muti part for each function.
#1 Export = Since each form is unique, how can i setup the page to export that forms data that is currently in the DB? (I've used this control before [URL] and worked great) for excel. This may work fine for exporting the data out of the db for the user.
#2 Import, if the above is used or some other solution to export the specific table data, is there anyway to validate that the csv file that is being uploaded contains all the columns and is in the correct order? I mean if they were to export the data, but come back few days later to import it, and didnt realize that they selected a csv for another page or maybe they picked the right file, but while editing it they removed a comma or entered some data that would throw the format out of wack.. just looking for a way to read the selected file to import and compare to the table it is suppose to go into and make sure that the columns match and if possible, check for duplicates. I have read thru the forum and found ways to read the file into memory, set the data to a datatable or dataset and working with it that way.
So really looking for some good examples of being able to allow the export of data to .CSV and then allowing the data to be imported back into the table.(with validation in place before the import occurs)
instead of using gridview to insert student marks (I have hundreds of students) thought I used the Excel:
1) allow managers of each module after authentication to download the excel file (containing the students enrolled in the given module), the excel file ted is generated by the following code: Id_student ____ maks of subject1 -------- ----maks of subject2
[Code]....
But in this code I do not know how to:
* Add the following condition: the student'marks is between 0 and 20. * Calculate the average of this module : sum (coeff * mark) / sum (coeff)
2) Allowing responsable module send me the file containing the data (but then I do not know how)
3) Using data, by sending them to the database to calculate averages.
I'm still struggling with my scenario. I have looked everywhere for a solution and cannot find a solution. I am using C# and ASP.NET and I need to export data to an Excel spreadsheet.
I have a list of applications that contains Application objects. Each Application object has a status ID. When I export these applications to Excel then I need a column with a drop down/combo box in it. In this drop down/combo box should be a list of all the statuses from the database. And then I need the status to be selected to that of the application's status ID.
Another question is also with regards to the above scenario. When the user downloads the Excel document then the user can change the status of each application by selecting a different value in the drop down. I will need to upload this spreadsheet and loop through the rows and get the values of the columns and the value of the selected item in the drop down/combo box. How would you do this? Is this possible?
I may not use COM components, so I tried to go with EPPlus or NPOI (it does not have to be these 2) but it doesn't seem like they support my scenario. How would I be able to achieve my scenario? Once again, it doesn't have to make use of EPPlus and NPOI.
I have a report that I need to export to a txt file for EDI import. It adds extra blank lines at the bottom. This report is 1 line of text in the report footer. Any way to remove the extra lines that the export produces?
In my .net 2.0 application, i have used export / import excel option. In local, its working perfectly but in server i am getting the below errors,

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

i have different tables for product details, images, category mapping
is there any way to import/export products by excel file in database along with category mappying and pictures in one go rather that importing just the products and then categorizing each product and adding image one by one ?
This post is exactly my situation. Here's what his post says: (bolded key parts) I'm trying to get used to sql server 2008 having been forced to upgrade by my isp. I need to back up my key db on a weekly remote schedule, so have been trying to use ssms to export data from my remote db to a local copy.
Firstly I created a new empty db on the local machine. Then I scripted the structure of the db on the remote machine and ran the resulting query on the local machine to copy the table structure into the new db. This gave me empty target tables to map to (see below).
I used the export data wizard and selected my remote tables, then highlighted the tables to be copied and used the Edit Mappings option. Here I need to do two things, firstly checking'Enable Identity Insert' (because I have a unique id in most tables which is identity seeded, and I've read that if this is not checked sql server will helpfully renumber your entire table, rendering all your foreign key references useless). Secondly I need to decide what to do with the data already in the destination table. SQL 2k DTS simply dropped the destination table and recreated it. SQL 2008 will either keep the structure and delete the rows therein, or drop the table and recreate it. Because I intend to save this package and call it on a schedule in the future, I need to choose one of these options, because next time the target db won't be empty.
If I choose the delete rows option, when the package runs I get the following error when the process gets ot the first table with an identity ID which is used elsewhere in the db as a foreign key.
Error 0xc002f210: Preparation SQL Task 4: Executing the query "Truncate TABLE [dbo][tblCompany] failed with the following error 'Cannot truncate table tblCompany because it is being referenced by a foreign key constraint. Possible failure reasons: Problems with the query, "Result Set" property not set correctly, parameters not set correctly or connection not established correctly'
Half a dozen preceding tables did seem to transfer fine, but the process falls down on this one table. What I want is for the process to ignore constraints whilst it does the backup.
Undeterred I tried the other option, dropping each table and creating a new version. This time I get the error:
Error 0cx0202009: Data Flow Task 1: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code 0x80004005. An OLE DB record is available. Source MS SQL Server Native Client 10.0. Hresult 0x80004005 Description "The statement has been terminated". An OLE DB record is available. Source MS SQL Server Native Client 10.0. Hresult 0x80004005 Description "Violation of Primary Key constraint 'PK_LoginClasses'. Cannot insert duplicate key in object 'dbo.LoginClasses'.
Then I try unchecking the Enable Identity Insert option to see what happens. This happens:
- Validating (Error)Messages Error 0xc0202049: Data Flow Task 1: Failure inserting into the read-only column "UserID". (SQL Server Import and Export Wizard)

Error 0xc0024107: Data Flow Task 1: There were errors during task validation. (SQL Server Import and Export Wizard)
I can't see any more options to try. So how do I get SSMS 2008 to do what Enterprise Manager 2k did with no drama?

In my workstation I can import the data without problems and I have Office 2010 installed. In the server I have installed AccessDatabaseEngine for Office 2010 and when I try to import the data I receive the following error: The external table is not in the expected format.

I am working on a C# web application under visual studio 2005. I want to import data from text file or excel file into a SQL 2005 database. I have 3 columns in the text file separated by |, example of the text file format:

I have a web form that contains a GridView, which impliments Search in Grid with a TextBox and Button control in the footer. This works as I have it now. I have also implimented a Export to Excel function. The Export to Excel works by itself if the Search in Grid function is not included in the footer.The Export to Excel function errors when trying to render the Grid for the export. Is there a better way to incorporate both functions and accomplish the same thing? Am I missing something simple?
