Hi,
I created a C# program that update SQL Server table
row by row.
I referenced third party dll file to do the necessary
modification for each row.
And I used foreach loop to update data in the table.
The problem is the poor performance.
If I use the third party program, I can process 10,000
records within a minute, but if I try with my program,
it took almost 10 minutes for 10,000 records.
I tried to create index on the primary column before
update, but it didn't help much.
I know that cursor like update results slower performance,
but I need to process every single rows.
Does anyone know hot to improve performance in this
situation?
Thank you in advance.

It could be a few things..but the first that comes to mind is are you
leaving the connection open or are you closing it each time. Normally you
want to close a connectino immediately, but if you are iterating through a
loop 10,000 times, leaving it open until it's done processing( make sure you
have a close in the finally block though) may have a big performance
enhancing effect.
If you post the code, it may be easier to figure out.
HTH,

Dear Sql Server experts:
First off, I am no sql server expert :)
A few months ago I put a database into a production environment.
Recently, It was brought to my attention that a particular query that
executed quite quickly in our dev environment was painfully slow in
production. I analyzed the the plan on the production server (it
looked good), and then tried quite a few tips that I'd gleaned from
reading newsgroups. Nothing worked....

about 2.5 million rows (about 4 million in production) This query

any way to performance tune this?

am using FOR UPDATE triggers to audit a table that has 67 fields. My
problem is that this slows down the system significantly. I have
narrowed down the problem to the size (Lines of code) that need to be
compiled after the trigger has been fired. There is about 67 IF
Update(fieldName) inside the trigger and a not very complex select
statement inside the if followed by an insert to the audit table. When
I leave only a few IF-s in the...

This is a long post. You can paste the whole message
in the SQL Query Analyzer.
I have a scenario where there are records
with values pointing to wrong records and I need to fix them
using an Update statement.
I have a sample code to reproduce my problem.
To simplify the scenario I am trying to use Order related
tables to explain a little better the tables i have to work with.

been ruminating on the question (mostly in a 390/v7 context) of
whether, and if so when, a row update becomes an insert/delete.
i assume that there is a threshold on the number of columns of
the table, or perhaps bytes, being updated where the engine just
decides, screw it, i'll just make a new one.
surfed this group and google, but couldn't find anything.
the context: we have some java folk who like to parametize/

I installed the SQL Server 2005 SP2 update 2 rollup on my 64-bit
server and the performance has tanked!
I installed rollup 3 on some of them, but that did not seem to help.
I thought it was just a linked server performance issue, but my
optimization started running today on one of the "update 2" instances
and so far it's been running about 10 hours longer than it normally

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,...
