closer).

I want to enforce such a constraint on a column that would ensure that the
values be all unique, but this wouldn't apply to NULL values. (I.e. there
may be more than one NULL value in the column.)
How can I achieve this?
I suppose I would get the most-hated "table/view is changing,
trigger/function may not see it" error if I tried to write a trigger that
checks the uniqueness of non-null values upon insert/update.

Hi, folks.
I am writing a Javascript program that accepts (x, y) data pairs from
a text box and then analyzes that data in various ways. This is my
first time using text area boxes; in the past, I have used individual
entry fields for each variable. I would now like to use text area
boxes to simplify the data entry (this way, data can be produced by
another program--FORTRAN, "C", etc.--but analyzed online, so long as
it is first...

I have a table containing addresses with a separate field for State. Is there a
way to create a query that returns an unique list of the states in that table
and still be updateable? I tried setting the unique values property to Yes but
that gave me a recordset that was not updateable.
Thanks!
Marie

Hello.
New to ASP.NET and struggling on this one.
I have a text file with a bunch of text in it. Throughout the file
words followed by a ":" will appear. I need to pull every such string
out and then display all unique values.
I am able to read the file in, but am having trouble getting regex to
work. What regex and setting should I use?

Hey Guys,
Total Number of Records (Based on 5 fields): 1000
Total Unique Records (Based on 5 Fields): 990

have 2 fields that makes a record unique. I have used group by

Hi,
I have 125 unique variables and corresponding values in a data file with 6 fixed-width columns (columns alternate between "variables" and "values"). If I only need 6 of these variables and their values, which are scattered throughout the file, what are some suggestions to put into my script in order to extract them and them only? Is there a way to locate specific keys and ignore the others?
Thanks for your help!

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
