I'm working with a system usage database. I want to filter out
repetitive logins. The query I have retrieves data like this:
USER_DATE USER_TIME1 USER_USERID USER_ACCOUNT
10/01/2004 19:56 y708ga27 The Capital Group
10/01/2004 19:58 y708ga27 The Capital Group
10/01/2004 19:59 y708ga27 The Capital Group
10/01/2004 20:19 y708ga27 The Capital Group
In a case like this - with consecutive logins for the same user, if
the same user logged in more than once within 30 minutes, I want to
only retrieve one (remove duplicates), provided that the USER_ACCOUNT
is the same:
USER_DATE USER_TIME1 USER_USERID USER_ACCOUNT
10/01/2004 19:56 y708ga27 The Capital Group
Is the best way to do this through a query, report or form?
Thank you,
Tara 1 1393

Yeah, it's tricky. This might be a possibility.
Maybe create a Totals query that would select all records for the UserID
that groups on UserID and counts all records for that userID where the
Date/Time - 30 minutes has a count of 0.
Then create a query to select all records from the table where the
Totals query count is 0 for that useruid, date, time
This may not cover all bases. You'll have to experiment. In the above
example it would. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Good day all,
Ok, I have a pretty tricky problem that I need some help with.
I pass around search query information a fair amount (specifically
WHERE statements). Normally, I just rawurlencode() the buggers, and
pass them via the URL. I like having the where clauses in the URL,
because then someone can just bookmark the URL, or send it to a friend,
and I don't have to worry about a thing.
If someone does a search that requires a LIKE...

Hello, I'm trying to find the most optimal way to perform a tricky
query. I'm hoping this is some sort of standard problem that has been
solved before, but I'm not finding anything too useful so far. I have
a solution that works (using subqueries), but is pretty slow.
Assume I have two tables:
ItemID int (Primary Key)
ItemSourceID int
ItemUniversalKey uniqueidentifier

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
