Counting Field changes

As new Records are added I need to in a Query, count the number of
occurrences of several specific Fields that have change from the
previous record.
As a reference point, each Record is unique for Date and Time so if
the next Record is added to the DB, I want to know if Field 'x' has
changed in value from the entry in the previous Record.

Thank you,

Use one query to find the last row (excluding the one just entered)
using the max function. Then use another query with a max function to
find the record just entered. Now you can compare the two queries to
find if field x changed.

Hello: I have a form that contains a multiple-select field that has 12 options in it. I would like the user to be able to select UP TO FOUR of those options. If they select more than four, I would like to alert them of the error. To do this, I figure that counting commas would be the easiest method (i.e., IF commas > 3 THEN alert user). NOTE: I have an existing "validateForm" function for this form and I'd like to add this IF-THEN...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

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,...
