Hi,
Since Access doesn't support COUTN DISTINCT, I'm facing a new
problem I didn't take into account: how to get the count of PK's in a
complex query. I create queries on the fly -this means I can't use a

Someone (Kevin i think) was looking for a way to do a distinct count,
not sure if i'm using this groups thing right - was trying to supply
answer. Anyway, this is a function i wrote for it... hope it gets to
you. just copy and past it into a module and call it as you would
dcount()
Public Function CountDistinct(Field As String, QueryOrTableName As
String, AdditionalCriteria As String)
Dim dbs As Database

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" );

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
