Hi,
I have an Address table which contains more than one addresses for a
particular member. I want to write a query that would only display
most current address. All addresses have a unique ID (addID).
Example:
memberID addID address1
-------- ------ --------------------------------------------------
295 69 13 Auster St
295 70 465 Lorre Ct
295 71 P.O. Box 321
722 171 10 Hannaford Rd
722 172 Dubai, United Arab Emirates
>From the table data above. The query should only return
memberID addID address1
-------- ------ --------------------------------------------------
295 71 P.O. Box 321
722 172 Dubai, United Arab Emirates
I tried using Max and Group by function but it shows me all the rows.
If you can provide me with a sample code that would greatly
appreciated.

Assuming that each member's most current address has the largest
addID value, and that addID values are not re-used from one member
to the next:
select memberID, addID, address1
from the_table
where addID in (
select max(addID)
from the_table
group by memberID

I'm trying to write some C code, but I want to use C++'s std::vector.
Indeed, if the code is compiled as C++, I want the container to
actually be std::vector, in this case of a collection of value types or
std::vector<int>.
So where I would use an int* and reallocate it from time to time in C,
and randomly access it via , then I figure to copy the capacity and
reserve methods, because I just need a growable array.

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.

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,...
