Databases :: Upload Xlsx (MS Excel) File To Oracle DB?
Jan 18, 2011I would like to upload a xlsx file to Oracle DB (Oracle 11g). I'm using VS .NET 2008 (C#, web).
The file contains around 500 rows.
I would like to upload a xlsx file to Oracle DB (Oracle 11g). I'm using VS .NET 2008 (C#, web).

We have the data in excel file and want to upload the same into Oracle table.To achieve this we are using following query
insert into [ODBC:Driver={Microsoft ODBC for oracle};connectionstring].tablename (select * from sheet$ )
This is working fine for less records but when the record count increases following is the error faced. Error : System Resource Exceeded
We tried the following:
1. We tried to remove connection pooling for oracle.
2. We tried to remove connection pooling for excel.
3. We also verified that only one connection for each (oracle and excel) is open.
Our assumptions:
1. Either the server setting is the issue
2. Jet oledb Driver is the issue.
I need to be able to have a user upload an excel file, then immediately work with that file and save the contents in a database.
I know how to do this if I save the file first, then open it using OleDB, BUT I would rather not save it first.
I need to upload an excel file using a web application. Then I need t oread it in memory without saving it on the server.
Does the file need to have headers? Also the data is such that it may have or may not have values for some columns.
I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names.So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.

View 2 RepliesIn my application I've allowed users to upload Excel 2003 .xls files, and import them into a Gridview. This has been working fine using the following connection string:
[Code]....
Now my users are using Excel 2003, 2007 or 2010, I need to allow the newer file extensions (.XLSX) to be accessible too.
Therefore, within the connection string above I presume I could change the Excel version from 8.0 to 9.0 or 10.0 respectively, but is there much difference between Excel 2007 and Excel 2010 files?
If so, is it possible to 'detect' the Excel file version so that I can use the appropriate connection string to read the data from the files?
Excel cannot open the file "Report.xlsx" because the file format or extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file

I have a page within our site that allows admin users the ability to upload configuration settings into the system instead of submitting 1 at a time.
While testing yesterday, i found that one of the upload pages allowed me to upload a excel file that had alot more columns than expected and when i checked the database, the first few columns that were expected took the values from the file, and everything else was ignored, but wanted to see if there is any way to check the number of columns in the file to make sure it matches the upload logic before accepting it.
