Dear Group
I'm having trouble with the clause below. I would like to select only
records with a distinct TransactionDate but somehow it still lists
duplicates. I need to select the TransactionDate once as smalldatetime and
once as varchar as I'm populating a drop-down with Text/Value pairs. So I
can't just use 'SELECT DISTINCT TransactionDate FROM...'
I'm grateful for any hints.

alphanumerically using the following SQL:
SELECT distinct doc_number
FROM doc_line
WHERE product_id = 'WD' AND doc_type = 'O'
ORDER BY CASE WHEN IsNumeric(doc_number) = 1
THEN CONVERT(FLOAT, doc_number)
ELSE 999999999
END,

I have two tables, both containing an 'authors' column. Is there a way
to get a unique list of authors from the two tables?
I tried SELECT DISTINCT `authors` from `table1`, `table2`;
but I got an "Column 'authors' in field list is ambiguous" error.
Is there also a query to return only the count of distinct authors from
the two tables?
Thanks for any help.

Hi,
The line below is used to feed a combobox. (It is from a database which is
used to log pupil behaviour!) The 'incidents' table contains a list of
students who have been involved in incidents. Some may appear several
times, hence the Distinct. However, thelist generated should still be
sorted by Surname. When I add Order by I'm told it conflict with
the 'Distinct'. Surely it does not?
SELECT DISTINCT ., . & " " &

My boss has been adamant that SELECT DISTINCT is a faster query than
SELECT all other factors being equal. I disagree. We are linking an
Access front end to a SQL Server back end and normally are only
returning one record. She states that with disctinct the query stops
as soon as it finds a matching record. Both of us are relative novices
in database theory (obviously).
Can someone help settle this?

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
