Speed of pagination.

Hi,

My purpose is to make pagination for a table that selects from a large database. I need to jump to any page number (if the page size is 99 and I want to display the 111th page, I need to select as fast as possible the rows between10989 and 11088).

I used %VID BETWEEN :from and :to for the select query. Now, the %VID is available only if I select either from another nested select, or from a view. %VID does not work if I select directly from a table.

Hello,

I've recently updated the python version of a linux server running Red Hat Enterprise Linux 8.10 (Ootpa). We have an instance 2023.1 running there, and whenever I run the $System.Pyhthon.Shell() I can see it's still pointing to the old version. From within linux, it runs the latest one (we've change all the links to the new 3.11, so no scripts are broken).

So I guess the problem comes from the fact irispython is still compiled using old python version. So, how can I do to force IRIS to use the current version on the server, or update the irispython file?

I encountered an unexpected behavior while working with the $ZTIMEH and $ZTIME functions, specifically with times between 12:00 and 13:00. Here's what I observed:

W $ZTIMEH("08:50:38.975411826")
Output: 31838

W $ZTIME(31838,1)
Output: 08:50:38

This behavior is correct as $ZTIME returns the expected time of 08:50:38.

However, with the following example:

W $ZTIMEH("12:05:38.975411826")
Output: 338

W $ZTIME(338,1)
Output: 00:05:38

An IRIS.DAT file was removed, as it was not needed anymore. But the database was mirrored, so it still shows up in the mirror monitor and database list. How can this be fixed? There is no backup of the .DAT file so it cannot be restored.

w ##class(SYS.Mirror).RemoveMirroredDatabase("/mydir/")

throws a protect error.
