I need code that pulls up records of Accounts where last Payment Status was older than 6 months ago. But I'm not quite sure why my DateDiff won't work.
My code so far:
SELECT A.[AccountId]
,[AccountNumber]
,[AccountTypeId]
,[AccountStatusId]
,[CurrentBalance]
,[PaymentStatusID]
,D.Last_Change
FROM [Account] A
INNER JOIN (
SELECT AccountId
,MAX(Created) Last_Change
FROM PaymentStatusHistory
WHERE ToPaymentStatusID IN (1,2,11)
GROUP BY AccountId
) D
ON A.AccountID = D.AccountId
WHERE PaymentStatusID IN (1,2,11)
AND AccountStatusId IN (1,2)
--AND DATEDIFF (DAY, GETDATE(), D.Last_Change) > 180 --Need THIS line corrected.
ORDER BY CurrentBalance DESC, AccountNumber
You seem to have mixed up the starting_date and ending_date of your datediff.
AND DATEDIFF (DAY, D.Last_Change, GETDATE()) > 180
Get_date(), current date, should be after your Last_change date.
If you want a positive number, try reversing the order of the dates in your DATEDIFF.
For example: SELECT DATEDIFF(DAY,GETDATE(),'20170101') returns -250. SELECT DATEDIFF(DAY,'20170101',GETDATE()) returns 250.
I changed the order in the DATEDIFF and it worked.
AND DATEDIFF (DAY, D.Last_Change, GETDATE()) > 180
This line of code worked and gave me the result as needed.

I'm newish to SQL so sorry if the code is a little scruffy.
Basically I am creating a count of fire engines in use on every hour, which I have done, and that bit works. So I have a count of this for the past five years. Sorted.
But now I want to run it for a specific group of incidents (about 300 of them), showing how many engines were at that incident, every hour, and how many others were in use at the same time, but somewhere else.
My basic working code (that I modified from https://stackoverflow.com/a/43337534/5880512) is as follows. It just counts all P1 and P2 mobilisations at the defined time.
DECLARE #startdate datetime = '2018-05-03 00:00:00'
DECLARE #enddate datetime = '2018-05-05 00:00:00'
;with cte as
(
select #startdate startdate
union all
select DATEADD(minute, 60, startdate)
FROM cte
WHERE DATEADD(minute, 60, startdate) < #enddate
)
select convert(varchar(20), startdate, 120) as CreationTime, (select count(*) FROM MB_MOBILISATIONS WHERE MB_SEND < startdate and MB_LEAVE > startdate And (MB_CALL_SIGN Like '%P1' Or MB_CALL_SIGN Like '%P2')) as Count
from cte
option (maxrecursion 0)
To split these up for a particular incident, I can put the incident ref into the where clause, one as = so it will give me engines at that incident, and one as <> so it gives me the rest. This bit works too.
select convert(varchar(20), startdate, 120) as CreationTime, (select count(*) FROM MB_MOBILISATIONS WHERE MB_SEND < startdate and MB_LEAVE > startdate And (MB_CALL_SIGN Like '%P1' Or MB_CALL_SIGN Like '%P2') and MB_IN_REF = 1704009991) as 'At Incident'
, select convert(varchar(20), startdate, 120) as CreationTime, (select count(*) FROM MB_MOBILISATIONS WHERE MB_SEND < startdate and MB_LEAVE > startdate And (MB_CALL_SIGN Like '%P1' Or MB_CALL_SIGN Like '%P2') and MB_IN_REF <> 1704009991) as 'Other Incident'
The bit I can't work out to do, is to make this work for multiple incidents, without having to change the incident reference manually in the where clause for all 300.
The incident references I want to use will be stored in a temporary table. Ideally, I would like it to pick an ID, set the variables #startdate and #enddate, from the start and end of that incident, then do the hourly count for the duration of that incident.
Hopefully the results would look something like this
IncidentRef DateTime At Incident Other Incident
A 2018-05-03 1:00 4 2
A 2018-05-03 2:00 7 3
A 2018-05-03 3:00 5 3
A 2018-05-03 4:00 2 4
B 2017-03-01 9:00 7 2
B 2017-03-01 10:00 8 3
B 2017-03-01 11:00 6 1
B 2017-03-01 12:00 4 2
I hope that makes sense.
Thanks :)
Use something like this to limit the scope of your search to a smaller list. I've just added and referenced another CTE with a filter. If you're looking to parameterize the list you'll need a different approach like storing those id values in another table first.
with cte as (
select #startdate startdate
union all
select dateadd(minute, 60, startdate)
from cte
where dateadd(minute, 60, startdate) < #enddate
), mobi as (
select * from MB_MOBILISATIONS
where MB_IN_REF in (<insert list here>)
)
select convert(varchar(20), startdate, 120) as CreationTime, m."Count"
from cte cross apply (
select count(*) as "Count" from mobi
where MB_SEND < startdate and MB_LEAVE > startdate and
(MB_CALL_SIGN like '%P1' or MB_CALL_SIGN like '%P2')
) m;
I went ahead and rewrote your scalar subquery but I guess that's just a personal preference.
I have a table in MSSQL with the following structure:
PersonId
StartDate
EndDate
I need to be able to show the number of distinct people in the table within a date range or at a given date.
As an example i need to show on a daily basis the totals per day, e.g. if we have 2 entries on the 1st June, 3 on the 2nd June and 1 on the 3rd June the system should show the following result:
1st June: 2
2nd June: 5
3rd June: 6
If however e.g. on of the entries on the 2nd June also has an end date that is 2nd June then the 3rd June result would show just 5.
Would someone be able to assist with this.
Thanks
UPDATE
This is what i have so far which seems to work. Is there a better solution though as my solution only gets me employed figures. I also need unemployed on another column - unemployed would mean either no entry in the table or date not between and no other entry as employed.
CREATE TABLE #Temp(CountTotal int NOT NULL, CountDate datetime NOT NULL);
DECLARE #StartDT DATETIME
SET #StartDT = '2015-01-01 00:00:00'
WHILE #StartDT < '2015-08-31 00:00:00'
BEGIN
INSERT INTO #Temp(CountTotal, CountDate)
SELECT COUNT(DISTINCT PERSON.Id) AS CountTotal, #StartDT AS CountDate FROM PERSON
INNER JOIN DATA_INPUT_CHANGE_LOG ON PERSON.DataInputTypeId = DATA_INPUT_CHANGE_LOG.DataInputTypeId AND PERSON.Id = DATA_INPUT_CHANGE_LOG.DataItemId
LEFT OUTER JOIN PERSON_EMPLOYMENT ON PERSON.Id = PERSON_EMPLOYMENT.PersonId
WHERE PERSON.Id > 0 AND DATA_INPUT_CHANGE_LOG.Hidden = '0' AND DATA_INPUT_CHANGE_LOG.Approved = '1'
AND ((PERSON_EMPLOYMENT.StartDate <= DATEADD(MONTH,1,#StartDT) AND PERSON_EMPLOYMENT.EndDate IS NULL)
OR (#StartDT BETWEEN PERSON_EMPLOYMENT.StartDate AND PERSON_EMPLOYMENT.EndDate) AND PERSON_EMPLOYMENT.EndDate IS NOT NULL)
SET #StartDT = DATEADD(MONTH,1,#StartDT)
END
select * from #Temp
drop TABLE #Temp
You can use the following query. The cte part is to generate a set of serial dates between the start date and end date.
DECLARE #ViewStartDate DATETIME
DECLARE #ViewEndDate DATETIME
SET #ViewStartDate = '2015-01-01 00:00:00.000';
SET #ViewEndDate = '2015-02-25 00:00:00.000';
;WITH Dates([Date])
AS
(
SELECT #ViewStartDate
UNION ALL
SELECT DATEADD(DAY, 1,Date)
FROM Dates
WHERE DATEADD(DAY, 1,Date) <= #ViewEndDate
)
SELECT [Date], COUNT(*)
FROM Dates
LEFT JOIN PersonData ON Dates.Date >= PersonData.StartDate
AND Dates.Date <= PersonData.EndDate
GROUP By [Date]
Replace the PersonData with your table name
If startdate and enddate columns can be null, then you need to add
addditional conditions to the join
It assumes one person has only one record in the same date range
You could do this by creating data where every start date is a +1 event and end date is -1 and then calculate a running total on top of that.
For example if your data is something like this
PersonId StartDate EndDate
1 20150101 20150201
2 20150102 20150115
3 20150101
You first create a data set that looks like this:
EventDate ChangeValue
20150101 +2
20150102 +1
20150115 -1
20150201 -1
And if you use running total, you'll get this:
EventDate Total
2015-01-01 2
2015-01-02 3
2015-01-15 2
2015-02-01 1
You can get it with something like this:
select
p.eventdate,
sum(p.changevalue) over (order by p.eventdate asc) as total
from
(
select startdate as eventdate, sum(1) as changevalue from personnel group by startdate
union all
select enddate, sum(-1) from personnel where enddate is not null group by enddate
) p
order by p.eventdate asc
Having window function with sum() requires SQL Server 2012. If you're using older version, you can check other options for running totals.
My example in SQL Fiddle
If you have dates that don't have any events and you need to show those too, then the best option is probably to create a separate table of dates for the whole range you'll ever need, for example 1.1.2000 - 31.12.2099.
-- Edit --
To get count for a specific day, it's possible use the same logic, but just sum everything up to that day:
declare #eventdate date
set #eventdate = '20150117'
select
sum(p.changevalue)
from
(
select startdate as eventdate, 1 as changevalue from personnel
where startdate <= #eventdate
union all
select enddate, -1 from personnel
where enddate < #eventdate
) p
Hopefully this is ok, can't test since SQL Fiddle seems to be unavailable.
Hey how would I get data for a date column that's older than 6 months?
select * from myTable where dateColumn >
Thanks
Use DATEDIFF function.
Read more here: https://msdn.microsoft.com/en-us/library/ms189794.aspx
SELECT *
FROM myTable
WHERE DATEDIFF(MM, dateColumn, GETDATE()) > 6
SELECT * FROM myTable WHERE DATEDIFF(day, NOW(), dateColumn) > 180
select *
from table
where
date_column >=
DATEADD(m, -6, convert(date, convert(varchar(6), getdate(),112) + '01'))
I would use
select * from myTable where dateColumn > DATEADD(mm,GETDATE(),-6)
This way you arent applying a function on the lookup column, which in some cases can result in performance issues
Dateadd is very simple to use.
the first parameter is the interval, m means month, d means day ect. the second parameter is the increment, and the last one is obviously the date
select dateadd(m,6,getdate())
more info here
http://www.w3schools.com/sql/func_dateadd.asp
Once you understand dateadd then you can simply use it in where clause as such
Select * from Table1 where date1 >= dateadd(m,6,date1)
I have following data in my table activity_count
Activitydate |count
2013-12-20:18:25:45 10
2013-12-20:18:23:40 20
2013-12-20:17:25:45 5
2013-12-20:17:25:45 10
2013-12-20:17:25:45 10
I want to get the total counts for each hour,ie the result should be following
Activitydate |count
2013-12-20:18:00:00 30
2013-12-20:17:00:00 25
If you're using mySQL try below:
SELECT CONCAT(LEFT(DATE(activitydate),10),' ',HOUR(activitydate),':00:00') as DateHour,
SUM(count) as TotalCount
FROM activity_count
GROUP BY DATE(activitydate),HOUR(activitydate)
See my Demo.
However, if MSSQL try this one:
SELECT CAST(CAST(activitydate as DATE) AS nvarchar(15))+' '+CAST(datepart(HOUR,activitydate) as CHAR(2))+':00:00' as DateHour,
SUM([count]) as TotalCount
FROM activity_count
GROUP BY CAST(CAST(activitydate as DATE) AS nvarchar(15)),DATEPART(HOUR, activitydate)
See MSSQL Demo
please try this
select cast(cast(Activitydate as date) as datetime)+cast(datepart(hour,Activitydate),
count(*)
from activity_count
group by cast(cast(Activitydate as date) as datetime)+cast(datepart(hour,Activitydate)
Try HOUR function
select
Activitydate,
count(*) as 'count'
from activity_count
GROUP BY HOUR(Activitydate)
HOUR(time)
HOUR(time)
Returns the hour for time. The range of the return value is 0 to 23 for time-of-day values. However, the range of TIME values actually is much larger, so HOUR can return values greater than 23.
I have a SQL SERVER Table which has only one field "StartDate" the records are as follows
**
2011-07-28 19:30:00.000
2011-07-29 21:50:00.000
2011-07-25 09:20:00.000
**
What i want to do is :
SHOW RECORDS if its CURRENT DATE ( todays date ) and the time difference between current time the StartDate is not less then 5 minutes, i have written the following code but it doesnt show me the time difference ?
SELECT * FROM table WHERE DATEDIFF(day, StartDate, GETDATE()) <= 0
SELECT StartDate
FROM table
WHERE YEAR(StartDate)=YEAR(GETDATE())
AND MONTH(StartDate)=MONTH(GETDATE())
AND DAY(StartDate)=DAY(GETDATE())
AND (DATEDIFF(minute, StartDate, GETDATE()) >= 5
OR
DATEDIFF(minute, StartDate, GETDATE()) <= 5)
How about:
SELECT StartDate
,GETDATE()
,DATEDIFF(day, StartDate, GETDATE())
,DATEDIFF(minute, StartDate, GETDATE())
,*
FROM table
WHERE DATEDIFF(day, StartDate, GETDATE()) <= 0
AND DATEDIFF(minute, StartDate, GETDATE()) >= 5
There are two ways to do it one being DateDiff the other is DATEADD. Judging by the way I read your question DateAdd should do it. Here is an example;
SELECT *
FROM [dbo].[TABLE]
WHERE [LAST_UPDATE] > DATEADD(minute,-5,GetDate())
Using BETWEEN is probably a little more optimal than two AND statements (maybe not). Try not to do a calculation on each row if you don't have to. Doing DATEADD only on the current date will only be calculated once.
SELECT
whatever
FROM
table
WHERE
StartDate
BETWEEN FLOOR( CAST( GETDATE() AS FLOAT ) )
AND DATEADD(minute, -5, GETDATE())
I interpret the question as looking for rows where the date is today (between the start of today) but not within the last 5 minutes (and less than 5 minutes ago). That might not be what you were going for.
Hope that helps
