Hi,
I have created an MS Access database containing the following tables:
Crime
CrimeCommitted
Criminal
CriminalOrganiz ation
CriminalType
HideoutType
The Criminal table is the parent table that contains a one-to-many relationship with the CrimeCommitted Table (a criminal can commit many crimes). I've sorted the CrimeCommitted table in descending Date (that the crime was committed) so that the latest crime is at the top of the table.
What i need to do is to write a query to select only the lastest crime committed by a criminal. Then i will be retrieving this database from a Crystal Report to view the lastest crime for each criminal. I've tried using the SELECT DISTINCT statement
SELECT DISTINCT CriminalID FROM CrimeCommitted
and it returns each CriminalID once. But how can i write a query to retrieve only the lastest crime for each criminal?

- SELECT Criminal.CriminalID, Criminal.Name, Max(CrimeCommitted.Date) AS Last_Crime_Committed
-
FROM Criminal INNER JOIN CrimeCommitted ON Criminal.CriminalID = CrimeCommitted.CriminalID
-
GROUP BY Criminal.CriminalID, Criminal.Name;
- SELECT Criminal.CriminalID, Criminal.Name, Max(CrimeCommitted.Date) AS Last_Crime_Committed
-
FROM Criminal INNER JOIN CrimeCommitted ON Criminal.CriminalID = CrimeCommitted.CriminalID
-
GROUP BY Criminal.CriminalID, Criminal.Name;

I need to extract data from this table to find the lowest prices of
each product as of today. The product will be listed/grouped by the
name only, discarding the product code - I use SUBSTRING(ProductName,

I can get this result, but I had to use several views (totally
inefficient). I think this can be done in one efficient/fast query,
but I can't think of one.

I have a database I'm designing in Access 97. I have a custom field in a

"revision number" and looks for the last one for the given Doc (linked by

How can I run a single SP by asking multiple sales question either

We can use Northwind database for my question, it is very similar
to the structure of the problem on the database I am working on.

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
