I have a system that logs users who use the system daily. Some user may log in several times during the day which creates additional entries into the logging table in a date format as "'2012-06-01 00:50:59.000' "
What I'm trying to do is query and return back just one entry for the user (s) even if they are captured in the logging table more than once per day
(i.e. jbaker .'2012-06-01 00:50:59.000'
'2012-06-01 12:50:59.000'
'2012-06-01 15:50:59.000' )
I tried selecting distinct user (oprid) from the logging table (psaccesslog)but still came back with multiple entries for the day.
SELECT * FROM PSACCESSLOG
WHERE LOGINDTTM BETWEEN '2012-06-01 00:50:59.000' AND '2012-07-01 00:50:59.000'
ORDER BY OPRID, LOGINDTTM
Appreciate insight

When there are multiples which one do you want? It be far more helpful if you could post ddl and sample data with your problem. See the first link in my signature for best practices when posting questions.

I don't know the whole structure of your table, but this might give you something to start.

You might need to add some fields or add the extra time to get the 00:59:50.

Be aware that BETWEEN is inclusive for both values, so you might have values that get in two days.

CREATE TABLE #PSACCESSLOG(

opridvarchar(6),

logindttmdatetime)

INSERT INTO #PSACCESSLOG

SELECT 'jbaker', '2012-06-01 00:50:59.000' UNION ALL

SELECT 'jbaker', '2012-06-01 12:50:59.000' UNION ALL

SELECT 'jbaker', '2012-06-01 15:50:59.000'

SELECT oprid,

DATEADD( dd, DATEDIFF( dd, 0, LOGINDTTM), 0) AS LOGINDT,

COUNT(*) AS entries

FROM #PSACCESSLOG

WHERE LOGINDTTM BETWEEN '2012-06-01 00:50:59.000' AND '2012-07-01 00:50:59.000'

GROUP BY oprid, DATEADD( dd, DATEDIFF( dd, 0, LOGINDTTM), 0)

ORDER BY OPRID, LOGINDT

DROP TABLE #PSACCESSLOG
