Hi,
I'm just wondering if anyone has experience with bulk loading data into an
Oracle database with DBI.
My options are to use DBI or Oracle's sqlloader. I'd rather do it using DBI,
but I'm not sure what kind of perfomance hit I'll incur. I need to load 2
tables on a daily basis (~50MB).
Any comments?

Any help would be appreciated.
I am running a script that does the following in succession.
1-Drop existing database and create new database
2-Defines tables, stored procedures and functions in the database
3-Imports data using bulk insert
4-Analyzes data using stored procedures
I would like to improve the performance of the analysis in step 4 by

I've been doing some experiments with speeding up copying tables of
approximately 1 million rows between databases using BCP and BULK INSERT.
I noticed that the total time for removing the indexes (non-clustered) and
then recreating them after the BULK INSERT was significantly less than just
doing the BULK INSERT with the indexes left there, even though I specified
TABLOCK.
I would have expected SQL Server not to update the index until...

We have created CSV files on HPUX 11.0 and transferred them via ASCII ftp
to our SQL Server machine file store to load large amounts for data using
the BULK INSERT command. This is the command:
BULK INSERT db..table FROM 'S:\path\filename.csv'
WITH (
DATAFILETYPE = 'char',
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'

Right now I develop an application to retrieve over 30,000 records from a binary file and then load them into a SQL Server DB. So far I load those records one by one, but the performance is very poor: it takes more than 6 hours to finish the loading.
So could I make use of the bulk-insert mechanism of SQL Server to reduce the loading time in C# codes? or other performance improvement solutions?

Hi folks:
We have a system requirement where a large amount of data needs to be
transferred between two systems. The main system is a DB2 8.x running
on a pSeries (AIX) and the archive database resides on an iSeries
(AS/400).
At the end of the day, we would like to transfer the daily processed
data from the pSeries to the iSeries. Since the amount of data to be
transferred is large (in excess of 200,00 records), we would like a

Hello,
I have a db2load script I'm using to populate a large table.
Ideally, my target table is required to have "Not Null" constraints on
a number of different columns.
I've noticed a huge performance hit when I load the target table with
"Not Null" constraints as compared to loading a target table without
the constraints.

I have written a stored procedure that is used to load data into a SQL Server 2000 and 2005 databases from some 40ish different text files. One of the text files is loading all of the rows apart from the last one. No error message is issued when this happens.
The command I am using to load the data is as follows:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Here is the code in...

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. For most users, this new feature is actually very convenient. If you want to control the update process,...
