Inserting nothing takes a long time

Hi,
I've a strange problem with a INSERT query. It's taking a long time to
execute. The format is like this :

INSERT INTO table1
SELECT ..
FROM table2

Executing the SELECT .. FROM table2 is taking 30 seconds. The result
is nothing: no records are selected.

When i include the INSERT part it will take 12 hours to complete

INSERT INTO table1
SELECT ..
FROM table2

There's is an index on the table and when i delete it, it gives still
the problem.

Keh?

Greetz,
Hennie

Hi!
Is this a real problem? ;-)
Nothing to insert...??

Ok: what is the complete sql?
Remember caching can cause effect when running statement more than
once.

What does "set SHOWPLAN_ALL ON..." tell you?
What do you get when enabling:
SET STATISTICS TIME ON
SET STATISTICS IO ON

Well, I am back.

Hi, All: I know how to insert files into a Word doc using C#. However, the program I've written to do this runs much too slowly. The "myObj".Application.Selection.InsertFile method executes at a snails pace. Here are the detais: I wrote a C# program that creates a new Word doc and then loops through a list of HTML files to insert them into the new doc (sample code below). The purpose of the program is to make one Word doc out of all...

I am not sure if this is something that is covered by the Standard, or if it's an implementation detail of my Standard Library. I am reading in a large amount of data into a std::set. There is an overload for std::set::insert() that takes in an iterator as a hint as to where the new value should be inserted, and my implementation (Dinkumware) says that if the hint is good (meaning the iterator points immediately before or after where...

I am using VB.NET 2003 and SQL Server 2000. I have a table with a datetime column type. When inserting into the table for that column, I set it to Date.Now.ToString("T") , which is something like "2:50:54 PM". But after the row is inserted and I check the data in the database, the column data is set to "1/7/2007 2:50:04 PM" (notice today's date in front of the time). If I insert data directly into the table in the Enterprise Manager, the...

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,...
