Hi all,
Is there a way to find the position of a certain record (id) in a result
set, based on a (autonumber id)?
Example:
My table has 2 fields: id & name, and the contents =
id name
1 Hi
2 There
3 This
4 Is
5 A
6 Quesion
7 But
8 Is
9 It
10 Possible
Say the currently selected record is id=2 > this is the 2nd record in the
result set.
Say i show only 2 records per page, and the set is sorted by id
Select * from mytable order by id asc limit 0,2
will give:
1 Hi
2 There
Now, as my id = 2 (currently selected record), and the selected record is
the 2nd record in the total result set (no limit), but also the second
record of the first page (offset = 0)
if I change the sort order to name, asc, I still want the selected record
(id=2) to be show, so the page that record is on should be calculated:
Select * from mytable order by id asc limit 0,2 will show only the records 5
& 8, so I need to calculate a new offset.
5 A
7 But
1 Hi
4 Is
8 Is
9 It
10 Possible
6 Quesion
2 There
3 This
and now my id =2 is the 8th record in the result set... (or the first record
in the 5th page) (=10records/2 records per page)

Hi,
I recently encountered a problem while trying to create a report
grouped by certain time frames. However, Access only allows grouping in
Minutes or Hours. For example, the first time frame is from 5:30am to
6:20am, if I have record 1 with time = 5:30am, record 2 with time =
6:00am and record 3 with time = 6:30am, the report will group record 1,
2 & 3 together under 5:30am (if grouped on Minute) Or group record 1
under 5:30am and...

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,...
