SQL Server 2012 :: Difference Between Two Date / Times And Flag Each Hour In Between
Dec 31, 2013
I have a request where i would like to get the start date/time and end date/time and flag (with an int) which hours (24 hour clock) have values between the two dates. Example car comes into service on 2013-12-25 at 0800 and leaves 2013-12-25 at 1400 the difference is 6 hours and i need my table to show
Column: Hour_6 Value: 0
Column: Hour_7 Value: 0
Column: Hour_8 Value: 1
Column: Hour_9 Value: 1
Column: Hour_10 Value: 1
Column: Hour_11 Value: 1
Column: Hour_12 Value: 1
Column: Hour_13 Value: 1
Column: Hour_14 Value: 0
As i'm working away at it i'm trying to figure out how i could use a Time Dimension table for this but dont really see much. So far i have the difference between the two times in hours (hour_diff) and the start hour (min_hour) so i would like to do something where i update the first hour (min_hour) and update columns based on the numbers of hours (hour_diff)

I have Two Time fields in a table. Time(0). An "opening time" and a "closing time". They can hold any legit time.
I want to calculate in a SELECT Statement how many minutes within this range are within 9am to 5pm (which I'll convert to hours).
For example, here's an easy example:
OPEN: 9:00:00
CLOSE: 17:00:00
8 Hours/480 minutes
I could get this easy enough with a DATEDIFF function.
But what about:
OPEN: 08:00:00
CLOSE: 18:00:00
10 Hours total but only 8 of those 10 are within 9am-5pm.
Or what about:
OPEN: 10:00:00
CLOSE: 20:00:00
10 Hours total but only 7 are within 9am-5pm range.
I can calculate the total hours/minutes between the two times but not within that special range.

I have a table that stores working hrs, such as
RecID,StaffID,StartDate,EndDate
17,969,2015-05-18 00:00:00.000,2015-05-18 06:00:00.000
18,969,2015-05-18 18:00:00.000,2015-05-19 06:00:00.000
19,969,2015-05-19 18:00:00.000,2015-05-20 06:00:00.000
20,969,2015-05-20 18:00:00.000,2015-05-21 06:00:00.000
21,969,2015-05-21 18:00:00.000,2015-05-22 06:00:00.000
22,969,2015-05-22 18:00:00.000,2015-05-23 06:00:00.000
23,969,2015-05-23 14:00:00.000,2015-05-24 08:00:00.000
24,969,2015-05-24 22:00:00.000,2015-05-25 00:00:00.000
So working times can go over midnight, there can be more than one working period in a day etc.
For this staff member the summary of the weeks work will be
18/05/2015 - 12 hrs
19/05/2015 - 12 hrs
20/05/2015 - 12 hrs
21/05/2015 - 12 hrs
22/05/2015 - 12 hrs
23/05/2015 - 16 hrs
24/05/2015 - 10 hrs
Now for the complicated part, a person can take absence(sick,holiday,other) for any part of a day or whole day(s). For these absence periods only the worked time on that day needs to be negated off, not the whole period of time.
So for example
If this person
had a days holiday on the 22nd, shown in the HOLIDAY table as
StaffID,DateFrom, DateTo
969, 22/05/2015 00:00:00.000,22/05/2015 23:59:59.000
A Leave of Absence on the 20th, shown in the LEAVE table as
StaffID,DateFrom, DateTo
969,20/05/2015 12:00:00.000,20/05/2015 16:00:00.000
And was off sick on the morning of the 19th, shown in the SICKNESS Table as
StaffID,DateFrom, DateTo
969, 19/05/2015 00:00:00.000,19/05/2015 11:59:59.000
Now the Summary table should now show
18/05/2015 - 12 hrs
19/05/2015 - 6 hrs
20/05/2015 - 12 hrs
21/05/2015 - 12 hrs
22/05/2015 - 0 hrs
23/05/2015 - 16 hrs
24/05/2015 - 10 hrs
The 'Leave of Absence' on the 20th had no effect on the total for the day as it was between planned work times. how to do this within T-SQL, as simple as possible as I've got to had this code over to other staff members to maintain, who have not had much SQL experience yet?
I've tried doing it as a temp table, with dual insert/select commands, splitting the times over midnight, which partially worked but missed some of the combinations.

I am upgrading my application's SQL Server from 2008 R2 to 2012.
As discussed in the below URL I am able to see the Identity jump after I upgrade and the server is restarted.
Now since I cannot afford this and at this moment I do not have the time to create a sequence with NOCACHE and test it again I have to go ahead and add trace flag 272 in the start up parameter as this is the only solution which I can implement and even rollback without much hassles.
[URL] ....
What I got to know, this flag will disable the new feature of IDENTITY property that has been implemented as part of SQL Server 2012 and will make it work like it was doing in SQL Server 2008 R2.
But I want to know implementing this flag would impact any other feature or performance (except the performance of IDENTITY) of SQL Server.

I want to join 2 tables, table a and table b where b is a lookup table by left outer join. my question is how can i generate a flag that show whether match or not match the join condition ?
**The lookup table b for column id and country are always not null values, and both of them are the keys to join table a. This is because same id and country can have multiples rows in table a due to update date and posting date fields.
example table a
id country area
1 China Asia
2 Thailand Asia
3 Jamaica SouthAmerica
4 Japan Asia
example table b
id country area
1 China Asia
2 Thailand SouthEastAsia
3 Jamaica SouthAmerica
5 USA America
Expected output
id country area Match
1 China Asia Y
2 Thailand SouthEastAsia Y
3 Jamaica SouthAmerica Y
4 Japan Asia N

I am using MS SQL 2012 and have a pretty simple table dbo. Migration Breakdown with sample data as follows.
DepartDateTime ZoneMovement
2015-06-26 14:00:00.000 6 to 4
2015-06-26 14:00:00.000 11 to 7
2015-06-26 15:30:00.000 9 to 6
2015-06-26 21:00:00.000 7 to 3
2015-06-27 08:01:00.000 7 to 4
[code]....
What I am trying to do is parse the data set to find out when we have more than three like movements ex. 3 to 10 within ANY rolling 72 hour period. I have looked at the SQL Window Functions OVER with a ROW | RANGE subclause, but I can't find out how to tackle this rolling 72 hour business.

i am using this expression to get the time difference between two times.
{%Z.elapsed.time(@AK.VD.depart.date,@AK.VD.depart.time,@AK.VD.depart.date,@DV.VD.arrival.time,"hh.hh")*60} as [LOS (min)]
When Arrival time and depart time both are on same day above expression working to get the diference .
But if arrival date 2013-09-20 00:00:00.000 and arrival time 0800 and depart date 2013-09-21 00:00:00.000 and depart time 0050 when i calculate the time difference(using above expression) between these two i am getting -429.60 which is wrong. i have to get around 990.

Hello people,
I'm migrating an application from asp to asp.net and access to ms sql 2005. On the old db, there's a table with a column to store date and a column to store time. Ms sql only works with date and time together, right? I created a query to get the time from time column and update the date column inserting the time. I did something like this:
UPDATE S_ACC_MONEYSET Date_Oper = CONVERT(varchar, Date_Oper, 101) + ' ' + CONVERT(varchar, Time_Oper, 108)
Does anyone knows a better way to do that? Any other comments?
Thanks!

I have a table with the following columns employeeSessionID, OpDate, OpHour, sessionStartTime, sessionCloseTime. I need to see how many users remain active per hour. I can calculate how many logged in per hour, but I am stumped on how to count how many are active per hour. I have a single table that stores login data. I have created a query that pulls out the only the data needed from the table into a temp table using this query. Also note it is possible that the sessionCloseTime is null if the device has not been logged out this would need to be counted a active.
TABLE NAME #empSessionLog Contains the time stamp data OpDate, sessionStartTime and sessionCloseTime.

[code]....
can see how many sessions logged in per hour with the following statement:
SELECT
opDate,
FORMAT(DATEPART(HOUR, sessionStartTime), '00') AS opHour,
Count(*) AS Total
FROM #empSessionLog
Group BY opDate, FORMAT(DATEPART(HOUR, sessionStartTime), '00')
Order BY opDate, FORMAT(DATEPART(HOUR, sessionStartTime), '00') ASCResults:
opDateopHourTotal
2015-01-20041
[code]....
Where I am stuck is how do I count the sessions that remain active per hour until the session is closed with the sessionCloseTime.

Here's my predicament. I changed the filter on an article within a subscription, but not in a meaningful way. I just added "database.dbo." before a column name, but now my subscription is flagged for reinitialization, and won't replicate any transactions unless I start over with a new snapshot. I don't want that to happen. How can I reset the article properties somewhere to get it back the way it was and continue replicating transactions.
(I needed to add "database.dbo" so that another job that looks at the filter info would point to the correct database. Next time maybe I'll just modify the table that stores the filter info)
The reason I don't want to snapshot from the beginning is that I have procedures on the subscribing server that fire triggers from the transactions, so all the jobs "downstream" would get all out of sync.
HELP !

After carefully analyzing the situation for almost a month, I pulled the trigger and made an exception at work; we did enable trace flag 2371. We have some tables with billion of rows and outdated statistics causing horrible plans. Tried several methods to update those, but did not solve the problem or was too CPU intensive, causing other issues.
Anyway, one of the side effects I am seeing so far is average vCPU went down by almost 40%. Nothing out of usual (besides the flag) has been enabled or was executed. So my assumption is, CPU hungry plans are now gone or reduced.

from getdate(), how can i get today's date with specific time :
For example : (i just need specific 11oclock today)

This do the trick :
select DATEADD( HH, 11, CAST(CAST(DATEADD(DAY,-1,GETDATE()) AS INT) AS DATETIME))
But at second half of the day it changed from 2014-07-08 11:00:00.000 to the next day, i dont know why who controls the past controls the future, who controls the present controls the past. ¯(º_o)/¯ ~~~

I have @Year and @Month as parameters , both integers , example @Year = '2013' , @Month = '11'
SELECT T.[Year],
T.[Month]
-- select the sum for each year/month combination using a correlated subquery (each result from the main query causes another data retrieval operation to be run)
,
(SELECT SUM(Stores)
FROM #ABC
WHERE [Year] = T.[Year]
AND [Month] = T.[Month]) AS [Sum_Stores],
(SELECT SUM(SalesStores)
[code]....
What I want to do is to add more columns to the query which show the difference from the last month. as shown below. Example : The Diff beside the Sum_Stores shows the difference in the Sum_Stores from last month to this month.
Something like this :
+------+-------+------------+-----------------+-----|-----|---+-----------------
| Year | Month | Sum_Stores |Diff | Sum_SalesStores |Diff | Sum_Products |Diff|
+------+-------+------------+-----|------------+----|---- |----+--------------|
