Hi,
I was wondering if anybody knew of any other ways of efficiently
parsing a flat file into SQL Server 2000 using C#. The flat files are
tab delimited. And the general file size is around 1 GB so this code
has to be ultra efficient. Its a colllection of few flat files which
willl be mapped to a relational structure in the database.
Following are the options I am looking at:
1. Using Datasets to read the data and execute one stored procedure per
row. I am not finding this efficient at all obviously.
2. Reading the flat file, rewriting it so as to map it exactly to a
table and then using Interop to invoke Sql BCP utility. This approach
looks good but I would like to explore a bit more and see if I can
avoid using an interop.
Please only give me approaches you think can be explored. I am not
after code here yet.
Thanks.

If you are looking for real good effeciency, I would suggest looking at
csvReader ( http://www.csvreader.com). This guy has made an app that is
very effecient at importing data into sql server. He has it very
effecient to the point where the import can be as fast as running a DTS
from sql server.
Other than that, I would suggest using a BULK IMPORT sql statement:
BULK INSERT tableToImportTo FROM 'flatFile.csv' WITH (FIELDTERMINATO R =
',')
You'll have to change the field terminator to a tab, not sure what the
keyword to use there is.

I do something similar with a DTS package. I create & test the package in
enterprise manager, once I know for sure it does work I save it to file
(using one of the DTS screens) then I load it in the code and change the
source & target connection as needed. I found this pretty fast and
configurable.
I did not tried BCP though, so you should also explore that path.
BTW, you do not need to p/invoke BCP it's an executable that you run using
the Process class.

Dear all,
I have a requirement while parsing a delimited flat file and I was wondering
if there is a simpler solution that what I have in mind.
Basically I need to pull out a line from the flat file and the information I
am given is the line number and the name of the file. Therefore I have
thought of implementing something like this.
Private Function getLineFromFile(ByVal sFilePath As String, ByVal
lStringNo As Long) As String

Hi all,
I'm sure this is a popular question that comes up every few months
here. Indeed, I've looked at some of the past postings, but I would
like to ask things differently.
Basically, I'm using a flat file to storing data. I have to do this
because mySQL is not installed on my web server, and I am not the root
user. The amount of data is so small, that it isn't worth a full-blown
database anyway. However, while the data is...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
