Strange Select Distinct Behaviour

I have a table containing different field types including a memo field. If
I do a select distinct on the table the memo field is truncated to 256
characters. I've never encountered this before, is it a known issue?

Thanks.

Keith.

Hmm ... having thought about it, it must be perfectly reasonable behaviour.
You couldn't expect the db engine to compare almost infinite numbers of
characters.

Yes. Access 97 and earlier refused to do select distinct, giving a
warning. It was then possible to edit the query to do a left
(memofield,255) if you needed to include the field in the query.

Since Access 2000, the rules were changed, and Access now simply
truncates the field(s) to 255 characters. Stupid, stupid.

I am running a 9.0.1 database on a W2K server and have come across some strange behaviour with a SQL query. I have a query which runs in a PL/SQL cursor which has several PL/SQL variables used to switch on and off certain rules. One idea I had was to have two queries UNIONed together with a simple switch selecting which half was to operate (I know it sounds like there are probably better ways of doing this but I have my reasons). To cut...

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?

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?

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...

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,...
