I have a subquery that is taking multiple minutes to execute. If I pull out just the initial rows that are being added up, it only takes half a second with 2,400ish rows so I don't understand why the main query doing the sum is taking so long.
What I'm trying to do is for all the transactions in a date range, for all the workers assigned to those transactions, add up the scheduled hours for each worker.
The query is returning the correct data, it's just taking FOREVER to do it.
QUERY

UPDATE
Moving the trans_workers join out of the OUTER APPLY has reduced the execution time from 1 minute down to 16 seconds, so that's an improvement.

Thanks to https://www.sqlservercentral.com/forums/topic/consolidate-overlapping-date-periods I have a query that executes in under a second and returns what appear to be the correct hours. Only problem being I don't understand what's happening.

Bonus points to myself for conversions because the DATE of each transaction is in Clarion and the TIME of each transaction is a Unix timestamp
I have roster data that has night shift records (eg has start time of 2019-01-30 21:00:00.000 and a finish time of 2019-01-31 05:30:00.000 the following day.
I need to split this into 2 rows as follows
2019-01-30 21:00:00.000 to 2019-01-30 23:59:59.999
2019-01-31 00:00:00.001 to 2019-01-31 05:30:00.000
I need to retain all other info from the line. and the day date is the date the shift started.
SELECT actual_id
, emp_id
, emp_number
, area
, area_id
, day_date
, start_time
, finish_time
FROM Roster
WHERE CONVERT(date,start_time, 112) <> CONVERT(date,finish_time, 112)
To create two rows you can CROSS JOIN with a temp table having two rows like following.
select *
FROM roster
INNER JOIN
(
SELECT 1 temp
UNION
SELECT 2 temp )t
ON 1=1
Above query will replicate each row two times.
Now based on the row number (1 or 2) you can get the end time of a day and start time of a day like
CASE WHEN t.rownum =1 THEN start_time
ELSE dateadd(second, 1, Dateadd(day, Datediff(day, 0, finish_time), 0)
end starttime ,
CASE
WHEN t.rownum=2 THEN finish_time
ELSE dateadd(ms, -2, dateadd(dd, 1, datediff(dd, 0, start_time)))
END AS endtime FROM roster
Your final query should look like following query.
SELECT actual_id ,
emp_id ,
emp_number ,
area ,
area_id ,
day_date ,
CASE
WHEN t.rownum=1 THEN start_time
ELSE dateadd(second, 1, Dateadd(day, Datediff(day, 0, finish_time), 0)
end starttime ,
CASE
WHEN t.rownum=2 THEN finish_time
ELSE dateadd(ms, -2, dateadd(dd, 1, datediff(dd, 0, start_time)))
END AS endtime FROM roster
INNER JOIN
(
SELECT 1 rownum
UNION
SELECT 2 rownum)t
ON 1=1
WHERE CONVERT(date,start_time, 112) <> CONVERT(date,finish_time, 112)
Please try the mentioned solution:
SELECT
s.emp_id,
f.theDay
FROM Roster AS s
CROSS APPLY (SELECT
DATEADD(DAY, Number, s.start_time)
FROM master..spt_values AS v
WHERE v.Type = 'P'
AND v.Number BETWEEN 0 AND DATEDIFF(DAY, s.start_time, s.finish_time)) AS f (theDay)
ORDER BY s.emp_id,
f.theDay
Perhaps I am making this more complicated that it really is, hopefully someone can point me in the right direction. I get pretty close this this query:
SELECT
Action, TimeOccurred,
COUNT(Action)
FROM
[].[dbo].[]
WHERE
Action LIKE '%Logon Failed%'
AND (DATEDIFF(day, TimeOccurred, GETDATE()) BETWEEN 0 AND 30)
GROUP BY
Action, TimeOccurred
ORDER BY
TimeOccurred
My problem is TimeOccurred is formatted like this: 2017-05-13 00:02:00 so right now instead of giving me all the "logon failed" events per day, I get it per hour/min/second as well.
I would like to essentially cut the hh:mm:ss off so my results are per day. Hopefully that makes sense.
You can convert() to date to truncate the time portion of a datetime data type.
select
Action
, TimeOccurred = convert(date,TimeOccurred )
, Count(Action)
from [].[dbo].[]
where Action like '%Logon Failed%'
and TimeOccured >= dateadd(day,-30,dateadd(day, datediff(day, 0, getdate()), 0))
group by Action
, convert(date,TimeOccurred)
order by TimeOccurred
For your where, you can calculate the date for 30 days ago instead of getting a datediff() and restricting that range to 0-30.
For conditional aggregation you could do something like this:
select
TimeOccurred = convert(date, TimeOccurred)
, logon_kerberos = count (case when Action like ' %logon (kerberos)%' then 1 end)
, logon_local_wts = count (case when Action like ' %logon (local/wts)%' then 1 end)
, logon_ntlm = count (case when Action like ' %logon (ntlm)%' then 1 end)
, logon_total = count (case when Action like ' %logon (%' then 1 end)
, Count(Action)
from [CPTRAX_for_Windows].[dbo].[Logon_Logoff_and_Failed_Logon_Profiles]
where Action like '%Logon (%'
and TimeOccurred >= dateadd(day, -30, dateadd(day, datediff(day, 0, getdate()), 0))
group by convert(date, TimeOccurred)
order by TimeOccurred
You can use a Calendar or dates table for this sort of thing.
For only 152kb in memory, you can have 30 years of dates in a table with this:
/* dates table */
declare #fromdate date = '20000101';
declare #years int = 30;
/* 30 years, 19 used data pages ~152kb in memory, ~264kb on disk */
;with n as (select n from (values(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) t(n))
select top (datediff(day, #fromdate,dateadd(year,#years,#fromdate)))
[Date]=convert(date,dateadd(day,row_number() over(order by (select 1))-1,#fromdate))
into dbo.Dates
from n as deka cross join n as hecto cross join n as kilo
cross join n as tenK cross join n as hundredK
order by [Date];
create unique clustered index ix_dbo_Dates_date
on dbo.Dates([Date]);
Without taking the actual step of creating a table, you can use it inside a common table expression with just this:
declare #fromdate date = dateadd(day , datediff(day , 0, getdate() )-30 , 0);
declare #thrudate date = dateadd(day , datediff(day , 0, getdate() ), 0);
;with n as (select n from (values(0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) t(n))
, dates as (
select top (datediff(day, #fromdate, #thrudate)+1)
[Date]=convert(date,dateadd(day,row_number() over(order by (select 1))-1,#fromdate))
from n as deka cross join n as hecto cross join n as kilo
cross join n as tenK cross join n as hundredK
order by [Date]
)
select [Date]
from dates;
Use either like so:
select
TimeOccurred = d.Date
, logon_kerberos = count (case when Action like ' %logon (kerberos)%' then 1 end)
, logon_local_wts = count (case when Action like ' %logon (local/wts)%' then 1 end)
, logon_ntlm = count (case when Action like ' %logon (ntlm)%' then 1 end)
, logon_total = count (case when Action like ' %logon (%' then 1 end)
, Count(Action)
from Dates d
left join [CPTRAX_for_Windows].[dbo].[Logon_Logoff_and_Failed_Logon_Profiles] l
on d.Date = convert(date,l.TimeOccured)
and l.Action like '%Logon (%'
where d.Date >= dateadd(day, -30, dateadd(day, datediff(day, 0, getdate()), 0))
group by d.Date
order by d.Date

What we're doing is -
Building a numbers table
Using that to pull a list of days, with two records per day
Working out the start & finish times for each time window
Joining the time windows to the records and summing
Hope that helps :-)
Add another column to your select....
CASE
WHENE DATEPART(HOUR, Planned_SHIP_DATE) < 12 THEN 'AM' ELSE 'PM'
END AS ShipPeriod
You could then add that column into a GROUPING to seperate the 'AM's from 'PM's
Of course I have assuumed you wanted AM/PM. But you can modify the CASE statement to break the hours up as you see fit.
Hope this helps
Thank you all for helping me out.

This is the query I'm currently working with:
/* Number of successful logins per minute for a given date range */

GROUP BY DATEADD(minute, DATEDIFF(minute, 0, AuditMessage.EventDateTime), 0)
ORDER BY DATEADD(minute, DATEDIFF(minute, 0, AuditMessage.EventDateTime), 0)

I tried to modify the above query to get the desired output, but every path I've gone down has been a dead end. Any help would be greatly appreciated. Thank you.
If your database doesn't have every min of the day, it won't be able to get desired output. Unless you backend/whatever will insert a record to your table every min or refer to this link Fill empty dates in a matrix SSRS. Then you can modify your query like this
SELECT
DATEADD(minute, DATEDIFF(minute, 0, AuditMessage.EventDateTime), 0) AS Time,
ISNULL(COUNT(AuditMessage.EventTypeCodeUid),0) AS CountSuccessfulLoginAttemptsPerMinute
FROM IRWSDB.dbo.AuditMessage
JOIN AuditEventTypeCode
ON AuditEventTypeCode.EventTypeCodeUid = AuditMessage.EventTypeCodeUid
WHERE AuditEventTypeCode.DisplayName = 'Login'
AND AuditMessage.EventDateTime >= CONVERT(DATETIME, '2016-03-03 00:00:00', 120)
AND AuditMessage.EventDateTime <= CONVERT(DATETIME, '2016-03-04 00:00:00', 120)
GROUP BY DATEADD(minute, DATEDIFF(minute, 0, AuditMessage.EventDateTime), 0)
ORDER BY DATEADD(minute, DATEDIFF(minute, 0, AuditMessage.EventDateTime), 0)
First, you need to generate all minutes in the date range. To do this, you need a Tally Table. Then do a LEFT JOIN on your original query.
DECLARE #start DATETIME,
#end DATETIME
SELECT #start = '20160303', #end = '20160304'
;WITH E1(N) AS(
SELECT 1 FROM(VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1))t(N)
),
E2(N) AS(SELECT 1 FROM E1 a CROSS JOIN E1 b),
E4(N) AS(SELECT 1 FROM E2 a CROSS JOIN E2 b),
CteTally(N) AS(
SELECT TOP(DATEDIFF(MINUTE, #start, #end) + 1) ROW_NUMBER() OVER(ORDER BY(SELECT NULL))
FROM E4
),
CteMinute(dt) AS(
SELECT dt = DATEADD(MINUTE, N-1, #start) FROM CteTally
)
SELECT
cm.dt AS [Time],
ISNULL(t.cnt, 0) AS CountSuccessfulLoginAttemptsPerMinute
FROM CteMinute cm
LEFT JOIN (
SELECT
DATEADD(MINUTE, DATEDIFF(MINUTE, 0, am.EventDateTime), 0) AS [Time],
COUNT(am.EventTypeUid) AS cnt
FROM IRWSDB.dbo.AuditMessage am
INNER JOIN AuditEventTypeCode atc
ON atc.EventTypeCodeUid = am.EventTypeCodeUid
WHERE
atc.DisplayName = 'Login'
AND am.EventDateTime >= #start
AND am.EventDateTime <= #end
GROUP BY DATEADD(MINUTE, DATEDIFF(MINUTE, 0, am.EventDateTime), 0)
) t
ON cm.dt = t.[Time]
GROUP BY cm.dt
One way is to use LEFT JOIN of "list of every minutes" to your current query
2nd way is to UNION ALL the current query with the "list of every minutes" and then do a SUM on the Count
There are may ways to create the "list of every minutes" like using tally/number table, recursive cte, cross join etc.
Here is a method using recursive cte
;with minutes as
(
select Time = convert(datetime, '2016-03-03')
union all
select Time = dateadd(minute, 1, Time)
from minutes
where Time < '2016-03-05'
)
select Time
from minues
Method 1 : LEFT JOIN
;with minutes as
(
select Time = convert(datetime, '2016-03-03')
union all
select Time = dateadd(minute, 1, Time)
from minutes
where Time < '2016-03-05'
),
data as
(
< your current query here without the order by clause>
)
