I want to build query to return how many rows are in this query:
select distinct c1, c2 from t1
But SQL won't accept this syntax:
select count (distinct c1, c2) from t1
Does someone know how to count multiple distinct columns? Thanks.

Hi,
I'm trying to display the total page views per page within a given date
range, but the correct SQL is seemingly beyond me. I get the correct result
with a straightforward Group By and Count clause eg
SELECT DISTINCT tblPageViews.PageVisited,
Count(tblPageViews.PageVisited) AS CountOfPageVisited
FROM tblPageViews
GROUP BY tblPageViews.PageVisited;

I am trying to get a exact count of different distinct entries in an
Access column. At first, I was trying to work with three columns, but
I've narrowed it down to one to simplify it. I've searched Google
Groups for Distinct Count and Count, the Microsoft Help file (which
apparently has bad links in Office 2003), and looked at other files,
but I can't find the answer. The closest I've been able to get is to

I have a single DataTable in a DataSet. It has 4 columns and i'd like to
get a handful of counts of unique items in 3 of the 4 columns.
Can a DataTables Select or Compute methods to COUNT DISTINCT?
These two attempts failed
DataRow dr = ds.Tables.Select( "COUNT(DISTINCT(site_name))" );
object x = ds.Tables.Compute( "COUNT(DISTINCT(site_name))",
"ProductionCount > 0" );

Situation: I'm using vb.net to create a query that will populate a

I'm trying to write a query that will select a distinct count of more
than one field. I have records that display user productivity. Each of
the records have a time associated with it and I want to be able to
tell the distinct count of the products numbers and of the pallets ID
that they worked with. Do need to work out some sort of sub-query to do
this?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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...
