I am trying to find the sql statement needed to extract, from a table of
data with multiple instances of a id no,
a list of unique id nos, picking the latest (by datestamp which is stored as
a second field) so that a master list is updated.
The application is a list of student photos, each database row defines the
filename of a photo, the student id is assigned to the
photo once it is known, I then need to produce a list for all photos showing
the details of the latest photo for each student.
SELECT * FROM Photosforimport ORDER BY adno, Lastupdatetime DESC
Gives me the data I need, however I need to be able to just pick out the row
with the latest Lastupdatetime for each ADNO.
I couldn`t find anything on google, but may have been asking the wrong
question!
Any help greatly appreciated.
