getting in trouble with multiple insert...

Michael Schoen

Hi there,

i=B4m actually developing a performance criticial system where I need to
index a huge amount of protocoll data.

These data are already in a chronological order, so if I push the data
one by one in the database I will never need an ORDER BY syntax, `cause
mysql already stores the data the right way. That=B4s tweaking, isn=B4t it
;)

Unfortunatly I need more than 2000 inserts/sec, so simple inserts are
just too slow. Therefore I used that WONDERFUL multiple insert statement
and the speed was no problem any more.

BUT with the multiple insert statment the chronological order will be
lost and I=B4ll need the ORDER BY syntax again. And the query-speed goes
down to not usable ;(

To be honest, I don=B4t really see a reason WHY the chronological ORDER is
lost this way, but maybe this problem could also be solved with a simple
trick <g>

Maybe one of the developer could say more? Or any other ways to deal
with that problem?
Mit freundlichen Gr=FC=DFen / Kind Regards

Expanding Hierachy with multiple parents

by: John Smith | last post by:

I have a user assigned multiple roles and a role can be inherited from multiple parents (see below). How do I answer such questions as "How many roles does the user belongs to?" I answered the above questions by using .NET but I think it can be more efficient by using just SQL. I would appreciate if you can give me an answer. Thank you.

Hello, What is the optimal way to insert multiple rows (around 1000) from a web application into a table? The user enters multiple lines into a text box (up to 10,000). The ASP.NET application breaks that data into a string array. Each line is an item of that array. The user clicks Submit.

Multiple-condition trigger trouble

Getting a single RTF document from multiple RTF controls

by: Neil | last post by:

Here's a follow-up to my "Concatenating Rich Textbox Controls Into A Single File" message. I didn't get any useful responses to that message, so I assume that there isn't a direct way to create a single RTF document from multiple RTF controls (using MS Rich Textbox control 6.0 in Access 2000). So here's the method I came up with. Create a temporary RTF document from each control; open Word through automation; create a new doc and then...

The easy way to turn off automatic updates for Windows 10/11

Overview: 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,...
