correct representation of timestamp difference

Hi
I'm trying to create a select statement that will return all rows that
are older than 30 milleseconds. Is either of these correct?
select event_id from event where (current_timest amp-timestamp)>.030
or
select event_id from event where
(current_timest amp-timestamp)>0000 00030.000000
thanks,
Phil

The first timestamp will always be "automatically generated time." So if the record is updated, or inserted, this time gets changed. However, if the column order is changed with an alter statement, this is no longer the case. create table t ( a int, b int, timeUpdate timestamp, timeEnter timestamp );

So, I got the itch to write something more... I apologize for not doing more on the attempted "Correct C++ Tutorial" earlier, but there were reasons. This is an UNFINISHED and RAW document, and at the end there is even pure mindstorming text left in, but already I think it can be very useful. <url: http://home.no.net/dubjai/win32cpptut/special/pointers/preview/pointers_01__alpha.doc.pdf>.

Dear all, I found that I can't update or delete a DB2 record with timestamp using Access through ODBC. The Access complains "No current record" while I attempt to update or delete the record with timestamp. Do anyone have idea of how to fix this problem? Thanks in advance!

I have a table with a few million rows of temperature data keyed by timestamp. I want to group these rows by timestamp intervals (e.g. every 32 seconds), compute aggregate functions on the columns, and ultimately feed the result into a graph-drawing web thingy. I'm trying a few different ways to get what seems to be the same data, and seeing some odd behavior from the query planner. The table looks like this:

I know this could be a dumb question, I just want to confirm that it is faster to execute inserts, if a timestamp field is set to have a default value, like DEFAULT CURRENT TIMESTAMP, and skip that column in inserts, than to include explicit timestamps in the inserts and let the DB insert them. Thanks!

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents.
