I have a table with data every hour:
and a table with data every 30 minutes:
I would like to join these two tables (by date) to get batVolt and TA in the same table and repeat the values for batVolt for the 30 minutes between the hour.
SELECT *
FROM HourTable t
INNER JOIN HalfHourTable ht
ON CAST(t.repDate AS Date) = CAST(ht.repDate AS Date)
AND DATEPART(HOUR, t.repDate) = DATEPART(HOUR, ht.repDate)
Edit
Your query should be
SELECT n.repDate
, n.TA
, a.batVolt
FROM [DAP].[dbo].[ARRMet] AS n
FULL JOIN [DAP].[dbo].[array3] AS a
ON DATEPART(HOUR, n.repDate) = DATEPART(HOUR, a.repDate)
AND CAST(n.repDate AS DATE) = CAST(a.repDate AS DATE)
WHERE CAST(n.repDate AS DATE) = '20150831'
ORDER BY n.repDate DESC
I would do this slightly differently than M.Ali. This uses fewer functions and seems a bit simpler to me.
SELECT *
FROM HourTable t
INNER JOIN HalfHourTable ht on
t.repDate = dateadd(hour, datediff(hour, 0, ht.repDate), 0)
You could use DATEPART()
select ta.repDate, ta.code, ta.TA, bat.batVolt
from table2 ta
join table 1 bat
on (DATEPART(yyyymmddhh,bat.repDate) = DATEPART(yyyymmddhh, ta.repDate)
I don't remember exact syntax for datepart but should be something similar to this
You can try following
SELECT x.*, y.*
FROM BatVoltDetails x
INNER JOIN TADetails y
ON LEFT(CONVERT(VARCHAR, x.repDate, 120), 13) = LEFT(CONVERT(VARCHAR, y.repDate, 120), 13)

I have this query, and it returns the following result, I need to delete the records repeated by date, and keep the oldest, how could I do this?
select
a.EMP_ID, a.EMP_DATE,
from
EMPLOYES a
inner join
TABLE2 b on a.table2ID = b.table2ID and b.ID_TYPE = 'E'
where
a.ID = 'VJAHAJHSJHDAJHSJDH'
and year(a.DATE) = 2021
and month(a.DATE) = 1
and a.ID <> 31
order by
a.DATE;
Additionally, I would like to fill in the missing days of the month ... and put them empty if I don't have that data, can this be done?
I would appreciate if you could guide me to solve this problem
Thank you!
The other answers miss some of the requirement..
Initial step - do this once only. Make a calendar table. This will come in handy for all sorts of things over the time:
DECLARE #Year INT = '2000';
DECLARE #YearCnt INT = 50 ;
DECLARE #StartDate DATE = DATEFROMPARTS(#Year, '01','01')
DECLARE #EndDate DATE = DATEADD(DAY, -1, DATEADD(YEAR, #YearCnt, #StartDate));
;WITH Cal(n) AS
(
SELECT 0 UNION ALL SELECT n + 1 FROM Cal
WHERE n < DATEDIFF(DAY, #StartDate, #EndDate)
),
FnlDt(d, n) AS
(
SELECT DATEADD(DAY, n, #StartDate), n FROM Cal
),
FinalCte AS
(
SELECT
[D] = CONVERT(DATE,d),
[Dy] = DATEPART(DAY, d),
[Mo] = DATENAME(MONTH, d),
[Yr] = DATEPART(YEAR, d),
[DN] = DATENAME(WEEKDAY, d),
[N] = n
FROM FnlDt
)
SELECT * INTO Cal FROM finalCte
ORDER BY [Date]
OPTION (MAXRECURSION 0);

Now we can write some simple query to stick your data (with one small addition) onto it:
--your query, minus the date bits in the WHERE, and with a ROW_NUMBER
WITH yourQuery AS(
SELECT a.emp_id, a.emp_date,
ROW_NUMBER() OVER(PARTITION BY CAST(a.emp_date AS DATE) ORDER BY a.emp_date) rn
FROM EMPLOYES a
INNER JOIN TABLE2 b on a.table2ID = b.table2ID
WHERE a.emp_id = 'VJAHAJHSJHDAJHSJDH' AND a.id <> 31 AND b.id_type = 'E'
)
--your query, left joined onto the cal table so that you get a row for every day even if there is no emp data for that day
SELECT c.d, yq.*
FROM
Cal c
LEFT JOIN yourQuery yq
ON
c.d = CAST(yq.emp_date AS DATE) AND --cut the time off
yq.rn = 1 --keep only the earliest time per day
WHERE
c.d BETWEEN '2021-01-01' AND EOMONTH('2021-01-01')
We add a rownumbering to your table, it restarts every time the date changes and counts up in order of time. We make this into a CTE (or a subquery, CTE is cleaner) then we simply left join it to the calendar table. This means that for any date you don't have data, you still have the calendar date. For any days you do have data, the rownumber rn being a condition of the join means that only the first datetime from each day is present in the results
Note: something is wonky about your question . You said you SELECT a.emp_id and your results show 'VJAHAJHSJHDAJHSJDH' is the emp id, but your where clause says a.id twice, once as a string and once as a number - this can't be right, so I've guessed at fixing it but I suspect you have translated your query into something for SO, perhaps to hide real column names.. Also your SELECT has a dangling comma that is a syntax error.
If you have translated/obscured your real query, make absolutely sure you understand any answer here when translating it back. It's very frustrating when someone is coming back and saying "hi your query doesn't work" then it turns out that they damaged it trying to translate it back to their own db, because they hid the real column names in the question..
FInally, do not use functions on table data in a where clause; it generally kills indexing. Always try and find a way of leaving table data alone. Want all of january? Do like I did, and say table.datecolumn BETWEEN firstofjan AND endofjan etc - SQLserver at least stands a chance of using an index for this, rather than calling a function on every date in the table, every time the query is run
You can use ROW_NUMBER
WITH CTE AS
(
SELECT a.EMP_ID, a.EMP_DATE,
RN = ROW_NUMBER() OVER (PARTITION BY a.EMP_ID, CAST(a.DATE as Date) ORDER BY a.DATE ASC)
from EMPLOYES a INNER JOIN TABLE2 b
on a.table2ID = b.table2ID
and b.ID_TYPE = 'E'
where a.ID = 'VJAHAJHSJHDAJHSJDH'
and year(a.DATE) = 2021
and MONTH(a.DATE) = 1
and a.ID <> 31
)
SELECT * FROM CTE
WHERE RN = 1
Try with an aggregate function MAX or MIN
create table #tmp(dt datetime, val numeric(4,2))
insert into #tmp values ('2021-01-01 10:30:35', 1)
insert into #tmp values ('2021-01-02 10:30:35', 2)
insert into #tmp values ('2021-01-02 11:30:35', 3)
insert into #tmp values ('2021-01-03 10:35:35', 4)
select * from #tmp
select tmp.*
from #tmp tmp
inner join
(select max(dt) as dt, cast(dt as date) as dt_aux from #tmp group by cast(dt as date)) compressed_rows on
tmp.dt = compressed_rows.dt
drop table #tmp
results:
This query almost does what I want
SELECT staging.dbo.ITEM_CODES.ITEM_CODE, MAX(dbo.OC_VDAT_AUX.UDL40) AS SAMPLEDATE,

Sample Table generated by query:
The end result that I am trying to achieve is the latest ITEM_CODE per unique LinkID Note the first and last rows in the table. The last row should not be pulled by the query.
How do I modify this query to make that happen?
I have tried various placements for DISTINCT and sub queries in the select and where statements.
I would do in your case with ROW_NUMBER window function and CTE.
Solution can be like this:

I have a query where I need to show 24 hour calls for each day.
But I am getting the hours which I have calls only.
My requirement is I need to get all the hours split and 0 if there are no calls.
Please suggest
Below is my code.
select #TrendStartDate
,isd.Name
,isd.Call_ID
,isd.callType
,DATEPART(HOUR,isd.ArrivalTime)
from [PHONE_CALLS] ISD WITH (NOLOCK)
WHERE CallType = 'Incoming'
and Name not in ('DefaultQueue')
and CAST(ArrivalTime as DATe) between #TrendStartDate and #TrendEndDate
The basic idea is that you use a table containing numbers from 0 to 23, and left join that to your data table:
WITH CTE AS
(
SELECT TOP 24 ROW_NUMBER() OVER(ORDER BY ##SPID) - 1 As TheHour
FROM sys.objects
)
SELECT #TrendStartDate
,isd.Name
,isd.Call_ID
,isd.callType
,TheHour
FROM CTE
LEFT JOIN [PHONE_CALLS] ISD WITH (NOLOCK)
ON DATEPART(HOUR,isd.ArrivalTime) = TheHour
AND CallType = 'Incoming'
AND Name NOT IN ('DefaultQueue')
AND CAST(ArrivalTime as DATe) BETWEEN #TrendStartDate AND #TrendEndDate
If you have a tally table, you should use that. If not, the cte will provide you with numbers from 0 to 23.
If you have a numbers table you can use a query like the following:
SELECT d.Date,
h.Hour,
Calls = COUNT(pc.Call_ID)
FROM ( SELECT [Hour] = Number
FROM dbo.Numbers
WHERE Number >= 0
AND Number < 24
) AS h
CROSS JOIN
( SELECT Date = DATEADD(DAY, Number, #TrendStartDate)
FROM dbo.Numbers
WHERE Number <= DATEDIFF(DAY, #TrendStartDate, #TrendEndDate)
) AS d
LEFT JOIN [PHONE_CALLS] AS pc
ON pc.CallType = 'Incoming'
AND pc.Name NOT IN ('DefaultQueue')
AND CAST(pc.ArrivalTime AS DATE) = d.Date
AND DATEPART(HOUR, pc.ArrivalTime) = h.Hour
GROUP BY d.Date, h.Hour
ORDER BY d.Date, h.Hour;
The key is to get all the hours you need:
SELECT [Hour] = Number
FROM dbo.Numbers
WHERE Number >= 0
AND Number < 24
And all the days that you need in your range:
SELECT Date = DATEADD(DAY, Number, #TrendStartDate)
FROM dbo.Numbers
WHERE Number < DATEDIFF(DAY, #TrendStartDate, #TrendEndDate)
Then cross join the two, so that you are guaranteed to have all 24 hours for each day you want. Finally, you can left join to your call table to get the count of calls.
Example on DB<>Fiddle
You can use SQL SERVER recursivity with CTE to generate the hours between 0 and 23 and then a left outer join with the call table
You also use any other Method mentioned in this link to generate numbers from 0 to 23

set dateformat ymd
declare #calls as table(date date,hour int,calls int)
insert into #calls values('2020-01-02',0,66),('2020-01-02',1,888),
('2020-01-02',2,5),('2020-01-02',3,8),

with cte as (select 0 n,date from #calls union all select 1+n,date from cte where 1+n <24)

I have a table with an engineerID, DateTimeCreated as DateTime, JobID and AuditTypeID
I need a query shows first (engineerID, JobID with AuditTypeID 1) and last (engineerID, JobID with AuditTypeID 2) on each row of the query.
SELECT TOP (100) PERCENT
dbo.AuditTrail.EngineerId,
dbo.AuditTrail.AuditTypeId,
dbo.Engineers.Name,
dbo.Engineers.EngineerTypeCode,
dbo.AuditTrail.JobId,
CAST(dbo.AuditTrail.DateTimeCreated AS Date) AS _Date
FROM
dbo.AuditTrail
INNER JOIN
dbo.Engineers
ON dbo.AuditTrail.EngineerId = dbo.Engineers.EngineerId
WHERE
(dbo.AuditTrail.AuditTypeId = 1) AND
(dbo.Engineers.EngineerTypeCode = 'p') AND
(dbo.Engineers.EngineerTypeCode = 'p') AND
(DATEPART(mm, dbo.AuditTrail.DateTimeCreated) = 6) AND
(DATEPART(YYYY, dbo.AuditTrail.DateTimeCreated) = 2014)
group by
AuditTrail.engineerID,
JobID,
AuditTypeId,
Engineers.name,
Engineers.EngineerTypeCode,
CAST(dbo.AuditTrail.DateTimeCreated AS Date)
ORDER BY
dbo.AuditTrail.EngineerID DESC
for the first part of my query. Unfortunatly I cannot see to select the first record for each day
Any help will be greatly appreciated
First just get the data you need, including the create date. Then grouping that data by date, select the min of each day. Finally, join the two sets, selecting only the minimum of each day -- that is, the first occurrence of each day.
with
AllMonth( EngineerId, AuditTypeId, Name, EngineerTypeCode, JobId, DateTimeCreated )as(
SELECT TOP (100) PERCENT
a.EngineerId,
a.AuditTypeId,
e.Name,
e.EngineerTypeCode,
a.JobId,
a.DateTimeCreated
FROM dbo.AuditTrail a
JOIN dbo.Engineers e
ON e.EngineerId = a.EngineerId
AND e.EngineerTypeCode = a.EngineerTypeCode
WHERE
a.AuditTypeId = 1
AND a.EngineerTypeCode = 'p'
AND a.DateTimeCreated >= DateAdd( mm, DateDiff( mm, 0, GetDate()), 0)
AND a.DateTimeCreated < DateAdd( mm, DateDiff( mm, 0, GetDate()) + 1, 0)
),
FirstByDay( MinDate )as(
select Min( DateTimeCreated )
from AllMonth
group by cast( DateTimeCreated AS Date )
)
select *
from AllMonth a
join FirstByDay f
on f.MinDate = a.DateTimeCreated
ORDER BY a.EngineerID DESC;
To get the last item of each day, just add a max to FirstByDay and add to the join. Work it into one long row if you really want to.
Btw, didn't I hear a few years back that the later versions of MSSQL ignored top (100) percent? I don't work with it much these days, and my memory is...well, just...somewhere around here...
I am trying to get the sum of "Qty" in a Table A called "Quote_Items" based on a "Required_by_Date" from Table B called Quotes. Both tables have a common "Quote_No" The required date is one month ago.
I have used the following but it produces a NULL, but I cannot see why
select sum(Qty)
from quotes.Quote_Items_Quantities
left outer join quotes.Quotes on (Quote_Required_by_Date = Qty)
WHERE (DatePart(yy, Quote_Required_by_Date) = DatePart(yy, DateAdd(m,1,getdate()))) and
datepart(m,Quote_Required_by_Date) = datepart(m,dateadd(m,1,getdate()))
Any suggestions what I am doing wrong here.
Try this:
SELECT SUM(i.Qty)
FROM Quote_Items i
JOIN Quotes q on i.Quote_No = q.Quote_No
AND CONVERT(varchar, q.Required_by_Date, 112) = CONVERT(varchar, DATEADD(month, -1, getdate()), 112)
or this (equivalent without using JOIN)
SELECT SUM(i.Qty)
FROM Quote_Items i
WHERE EXISTS(SELECT 1 FROM Quotes WHERE Quote_No = i.Quote_No AND CONVERT(varchar, Required_by_Date, 112) = CONVERT(varchar, DATEADD(month, -1, getdate()), 112))
Your query is producing NULL because of the join condition. You have
on Quote_Required_by_Date = Qty
However, the date is not going to match the quantity. Instead, you need to match on the Quote_No, according to your question:
select sum(Qty)
from quotes.Quote_Items_Quantities qiq left outer join
quotes.Quotes q
on q.Quote_Required_by_Date = qiq.Qty
WHERE (DatePart(yy, Quote_Required_by_Date) = DatePart(yy, DateAdd(m,1,getdate()))) and
datepart(m,Quote_Required_by_Date) = datepart(m,dateadd(m,1,getdate()));
You can also simplify your query by using the month() and year() functions:
select sum(Qty)
from quotes.Quote_Items_Quantities qiq left outer join
quotes.Quotes q
on q.Quote_Required_by_Date = qiq.Qty
WHERE year(Quote_Required_by_Date) = year(DateAdd(m, 1, getdate()) and
month(Quote_Required_by_Date) = month(dateadd(m,1,getdate());
Finally, you mind find it useful to use group by and get the results for many months:
select year(Quote_Required_by_Date), month(Quote_Required_by_Date), sum(Qty)
from quotes.Quote_Items_Quantities qiq left outer join
quotes.Quotes q
on q.Quote_Required_by_Date = qiq.Qty
group by year(Quote_Required_by_Date), month(Quote_Required_by_Date)
order by 1 desc, 2 desc;
