ADO.NET :: Option For User To Upload Excel File?
Feb 3, 2011I've an application built on asp.net 2.0. There is an option for user to upload excel file. Once the file has been uploaded the data in the file is validated against some business rules. Rows that successfully validates are inserted into database as soon as it is validated.
I use ado.net to connect to excel file. And use data reader to iterate over all the records. Normally the number of records range from 5,000 to 20,000. This process takes good 8 to 10 minutes. I want to optimize this process because to my understanding it takes too long. Currently I am looking at OPENROWSET, OpenDataSource which so far is unsuccessful. Valiation that takes place on every row is very simple. I only checks for maximum length. So validation itself is not an issue.

How To Upload An Excel File
Dec 2, 2010I am trying to upload an excel file and my code reads the data of excel one by one. Unfortunately as we all know that excel doesn't restrict the data type for each cells, so there is a chance and possibility that my code can catch the exceptions.
How can I do this?
Code:
try
{
// do the statement
}
catch
{
// throw the exception, log it and then proceed to the next, don't stop.
// then prompt the users of all exceptions encountered.
}
I need to process more than 1,000 rows of data from excel. I don't want every time there is an exceptions the uploading process stops and fixed the problem then re-upload the data again. I want to consolidate first all the data with issues or exceptions then deal with it later after the uploading process done.

Databases :: Upload Excel File Into Oracle - System Resource Exceeded
Jan 5, 2011We 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.
