Thanks for your quick reply John,
What if I want a count of users logged in by which database?
Like ADCN – 2 (even though 2 users logged in a total of 4x)

Well, your query will give you a count of all login records for the last 30 days by database. If you want a count by user logged in by date, you must add UserLoggedIn to the query and Group By. If you want a count of the different users, you must first SELECT DISTINCT WhichDatabase, DatePart(TimeLoggedIn) As LoginDate, UserLoggedIn FROM LogStats, then count that. If you just want a count of the different number of users, remove the LoginDate from the above DISTINCT query.

John. There are 4 fields in this table: WhichDatabase, TimeLoggedIn, TimeLoggedOut, UserLoggedIn and that is all.

P.S. It's not a good idea to include your address and phone info in your signature - these messages get posted on the web where scammers can scoop up info like that.

Greetings Pros,
I'm stuck on a query where I'm gathering usage data.
I am using a table called LogStats which captures the date logged in/out, the user, and the database.
My totals are not adding up correctly.
The easiest example is a small database where I have 4 logins from 2 users within the last 30 days. I have a query built that yields a count of 4 for these 2 users because I can't get the thing to show me 2 users logged in for that time period.
Here is the sql:
SELECT DISTINCTROW LogStats.WhichDatabase, Count(LogStats.UserLoggedIn) AS CountOfUserLoggedIn
FROM LogStats
WHERE (((LogStats.TimeLoggedIn)>Date()-30))
GROUP BY LogStats.WhichDatabase;
Please help. I am having a humbling experience because I think I should know better by now but ah well…
Respectfully,
Liz Ravenwood
