DataSource Controls :: Timed Out Saving Excel Data To SQL?
Jan 30, 2010
We have a web application that allows users to upload sales information in Excel format and store the information in our SQL server. The way it works is that the uploaded Excel file will be stored in a folder on the web server, the application will then open it up and read it row by row, and call a stored procedure to store each row's data. Now it is so slow that if the Excel file contains more than 75 rows of data, the application will just time out.
We have already increased the timeout limit by changing the executionTimeout to 300 seconds in the web.config file. Instead of increasing this further to wait for this slow process, I'm wondering if there are ways to speed it up. Is there a better way than calling the stored procedure row by row?
I have a gridview thats being populated from an excel file that is loaded through a fileupload control. I want to save the contents of that gridview to a table in my SQL database. I've searched the web and tried to loop through the gridview, but failed at it.
I have an application that is developed using VB.Net that is saving data in SQL Server 2008. in this application i have to save a big amount of data in one button click. When i say big i mean around 21000 record in one table. this is taking a lot of time since I'm calling the "Insert" procedure around 21000 time from my application. What i want to do is to find a way to put my data in a kind of container then let VS or SQL 2008 manage the saving. I'm thinking of putting the data in a dataset.
Is this the best solution, or is there any other way to reduce the saving time of the 21000 records?
I'm exporting data to Excel. I've to put some headings, some data from datatable and again some footer text. For that I'm using following Code. It works fine locally but when I publish it it gives error while saving excel file as I'm hosting it on shared server.
I am creating a SSIS package, where I am getting all the data into the excelsheet1, which is not formatted.
So i created a formated excelsheet2, where i am giving reference to excelsheet1 cells reference.
And I am sending email by attaching excelsheet2.
I am having issue when the data is updated, but my email attachment excel is showing old data. When i open the excelsheet1 it is being updated. I don't know why excelsheet2 is not updated automatically. I am using BIDS 2005 .
im using an excel file as a datasource for my gridview...i can pull all the data into the gridview fine. i am now hoping to allow the user to update the data in the excel file through the gridview. is it possible to update the excel file in this format i.e. allow the user the read/update the excel file as if its a database. i see some references in google that its not possible to update the excel file as the writeout causes problems. does anyone have this working...or should i look into trying to use another datasource.
i was hoping to use an excel file as the app is on a shared server and it would be handy just to have the excel file in the app folder as there is not much data involved.
I want to import a spreadsheet into SQL. The import/export wizard forces Column A to be a double. In Excel, the column is formatted as text. When I try to convert from double to text/varchar/nvarchar, the import process fails. Why can't I convert a number to text in SQL?
I want to upload data from an Excel Sheet into my DB. Now my major requirement is, I do not know the header count in the files to be uploaded and they may vary, for example one file may have 3 headers while some may have 6. and I want data of both these files to go into a single DB. That is, I want to dynamically generate columns in my DB, and store these values. So how do I go about achieving this.
I've used the Import/Export wizard to get data into SQL from Excel and it works great. When I want to reverse the process, however, I can't. I've gone through the wizard multiple times and I've done what I think is everything to try to get the data out. What am I doing wrong?
i am Using sql server 2005. i want to copy the data of the excel file to the table.
i wrote the query like :
INSERT INTO test(empId,empName,empMailId,empContactNo) SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=C: estExcel.xls', 'SELECT * FROM [Sheet1$]')
got the following error :
SQL Server blocked access to STATEMENT 'OpenRowset/OpenDatasource' of component 'Ad Hoc Distributed Queries' because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure. For more information about enabling 'Ad Hoc Distributed Queries', see "Surface Area Configuration" in SQL Server Books Online.
then did this
sp_configure 'show advanced options', 1; GO RECONFIGURE; GO sp_configure 'Ad Hoc Distributed Queries', 1; GO RECONFIGURE; GO
again am trying the same above query ,now am getting the following error:
Msg 7399, Level 16, State 1, Line 1 The OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)" reported an error. The provider did not give any information about the error. Msg 7303, Level 16, State 1, Line 1 Cannot initialize the data source object of OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)".
i want to copy the data of the excel sheet to the table.
had a look around and a couple come close to the problem I have, but there more evolved than me, so it seems quite basic.I basically, want to store the current DateTime of when a button is hit. In order to achieve this I have a field in the table of SQL DB called 'TimeStamp' (Although strictly speaking its not, thats just what I've called it) using Datetime Datatype. I think I'm skipping some stages in order to accomplish it, although I'm not sure what it is I'm missing/doing wrong :SHere is my code:
[Code]....
I just have DID have "obj.TimeStamp = DateTime.Now;" but states I need to convert it (unsure how to do) Adding "ToLongTimeString" after .Now asks if I invoked the method. I've also tried a few other ways (saveNow.Now etc... ) but to no avail.
I have a problem with saving hebrew into sqlserver.I've done it before in another computer but did not have problem.Now the hebrew is saved as '???'.About the field collation, it is latin1_general_cp1_ci_as in another DB I have in another computeranf also in the current field in the current DB.I guess it not the collation.Ialso tried to change the text field to varchar, but it still saves '???'.
I have the following code that creates a new Excel file in my C# code behind. When I attempt to save the file I would like the user to select the location of the save.
In Method #1, I can save the file my using the workbook SaveCopyAs without prompting the user for a location. This saves one file to the C:Temp directory.
Method #2 will save the file in my UsersDocuments folder, then prompt the user to select the location and save a second copy. How can I eliminate the first copy from saving in the UsersDocuments folder?
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
