I have the two joined tables below. I'd like to get only the one line from the REQUIREMENTS table with the most recent date (3/8/2019).
**PART** **REQUIREMENTS**
ID OH TIME PART ORDER QTY DATE
5512 5 21 5512 74619 102 3/8/2019
5512 74907 25 3/10/2019
5512 74908 41 3/19/2019
5512 74243 59 3/21/2019
When I use Min(REQUIREMENTS.DATE), I still get all four rows because of the unique data in both the ORDER and QTY tables. I'm pretty sure I need to use Select Top 1 [...] but I'm having trouble figuring out where to use it. Ultimately I'm looking to return:
PART DATE OH TIME ORDER QTY
5512 3/8/2019 5 21 74619 102
Can anyone point me in the right direction (SQL Server 2012)? Thanks in advance!

You can use a correlated subquery to do this:
SELECT *
FROM PART P
INNER JOIN REQUIREMENTS R ON
P.ID = R.PART
WHERE REQUIREMENTS.[DATE] = (SELECT MAX([DATE] FROM REQUIREMENTS WHERE R.PART = PART)
You can use APPLY, your choice if you want OUTER or CROSS.
SELECT p.ID, p.state, p.time
, r.qty, r.date1
FROM dbo.Part p
OUTER APPLY (
select top 1 qty, date
from dbo.Requirements
where part = p.ID
order by date1
) as r

I have a lot of explaining to do for the context of this question so bear with me.
At my company, we have a SQL Server database and I'm working in the Management studio 2014.
We have a table that's called Jobstatistics, which displays how many Jobs are done during Intervals of one hour each.
The table looks like this
The station field is basically different areas jobs can be done at.
As you can see, some rows are missing for certain intervals and this is because of the way this table gets filled with data. To fill this table we have a script running that looks at another table and aggregates the amount of jobs for all dates between this interval. In other words, if there aren't any jobs, there won't be a row inserted because there will be nothing to insert (no rows from the other table to aggregate any jobs on).
What I want to do here is fill in these extra intervals with 0 as the amount of Jobs. So there will always be the 24 intervals (hours) for each day and for each station. On top of that we have set targets which we would like to achieve and I declared these in another table, called JobstatisticsTargets, which you could call a calendar table to join the Jobstatistics table on.
The calender table looks like this
I have tried doing a left or right join so the missing intervals would get filled in and the Jobs would at least get NULL values, but the join clause doesn't do what I expect it to.
This is my tried attempt
SELECT a.[Station], a.[Interval], a.[Jobs], b.[28JPH], b.[35JPH]
FROM [JobStatistics] a
RIGHT JOIN [JobStatisticsTargets] b
ON CONVERT(VARCHAR(10),a.Interval,108) = b.Interval
WHERE DATEDIFF(DAY, a.Interval, GETDATE()) < 12
AND Station LIKE '138010'
ORDER BY a.Station, a.Interval
The LEFT JOIN does exactly the same as I would expect a normal join to do and it doesn't append any intervals with NULL values. (the query is just for one station and a few days so I could test easily)
Any help is much appreciated. I will check this topic regularly so be sure to ask any questions regarding the context if you have any and I will try to explain it as good as I can!
EDIT
With some help the query now looks like this
SELECT a.[Station], b.[Interval], a.[Jobs], b.[28JPH], b.[35JPH]
FROM [JobStatistics] a
RIGHT JOIN [JobStatisticsTargets] b
ON CONVERT(VARCHAR(10),a.Interval,108) = b.Interval
AND CONVERT(VARCHAR(10),a.Interval,110) = CONVERT(VARCHAR(10),GETDATE(),110)
AND Station LIKE '138010'
ORDER BY b.Interval
I filter on today's date now because otherwise the extra rows aren't what I want them to be at all. The problem is that I don't know an easy way of filling in my stations. I suppose I need a subquery for those or is there another way?
The problem now as well is that I can't do this query for different stations. I would expect 24 rows for each station representing all the intervals, but I get this as a result:
Station Interval Jobs 28JPH 35JPH
NULL 00:30:00 NULL 0 0
NULL 01:30:00 NULL 0 0
NULL 02:30:00 NULL 0 0
NULL 03:30:00 NULL 0 0
134040 04:30:00 2 0 0
136060 04:30:00 2 0 0
131080 04:30:00 2 0 0
138010 05:30:00 2 0 0
NULL 06:30:00 NULL 0 0
NULL 07:30:00 NULL 28 35
NULL 08:30:00 NULL 28 35
...
You filter on a field from the table which rows may not be presented in the join result: >>>AND Station LIKE '138010'
You should change your query and put this condition in ON CLAUSE, not in WHERE
check this script and let me know,
declare #t table(interval datetime,jobs int)
insert into #t VALUES('2017-04-28 05:30',1),('2017-04-28 06:30',5),('2017-04-29 06:30',5)
--select * from #t
;With CTE as
(
select cast('00:00' as time) as IntervalTime
union ALL
select DATEADD(MINUTE,30,IntervalTime)
from cte
where IntervalTime<'23:30'
)
,CTE1 AS(
select interval,jobs
,dense_rank()over( order by cast(interval as date))rn
from #t
)
select * FROM
(
select distinct case when t.interval is null then
DATEADD(day, DATEDIFF(day, 0,
(select top 1 interval from cte1 where rn=n.number)), cast(c.IntervalTime as datetime))
else t.interval end Newinterval,isnull(t.jobs,0) Jobs
from CTE c
left join cte1 t
on c.IntervalTime=cast(t.interval as time)
cross apply(select number from master.dbo.spt_values
where name is null and number<=(select max(rn) from cte1))n
)t4
where Newinterval is not null
Sorry for the poor title. I wasn't sure how to describe my problem. I've written a query that returns about 23,000 records. A lot of those records have similar information and I want to only select the records with the maximum of the field dbo.tblMsgsOnAir_Type8.fldBuddyLinkSigStrength. I've tried grouping by all of the other columns being selected, but it doesn't appear to work correctly. I don't fully understand SQL, especially the max and group functions. I can do simple max functions when I only want or need to select one thing. I don't understand how it works when I want to select a bunch of other data. Below is the query.
SELECT
dbo.tblmeterinfo.fldMeterSerialNumber AS "MOP_FNP_Meter",
dbo.tblMsgsOnAir_Type8.fldRBuddyId AS "MOP_FNP_FNID",
dbo.TBLMETERMAINT.fldmeterid AS "Meter_ID_Helped",
dbo.tblMsgsOnAir_Type8.fldCBuddyId AS "FNID_Helped",
dbo.fn_dt(dbo.tblMsgsOnAir_Type8.fldRBuddyToi) AS "TOI",
dbo.tblMsgsOnAir_Type8.fldBuddyLinkSigStrength AS "Sig_Str",
dbo.TBLSAWN_CIS_INFO.SML AS "Buddy_SML",
dbo.TBLMETERLIST.fldaddress AS "Buddy_Address",
dbo.TBLSAWNGISCOORD.X_COORD AS "X_Coord",
dbo.TBLSAWNGISCOORD.Y_COORD AS "Y_Coord"
FROM dbo.tblMsgsOnAir_Type8
LEFT OUTER JOIN dbo.TBLMETERLIST
ON (dbo.TBLMETERLIST.FLDREPID = dbo.tblMsgsOnAir_Type8.fldCBuddyId)
LEFT OUTER JOIN dbo.TBLMETERMAINT
ON (dbo.TBLMETERMAINT.FLDREPID = dbo.tblMsgsOnAir_Type8.fldCBuddyID)
LEFT OUTER JOIN dbo.TBLSAWN_CIS_INFO
ON (dbo.TBLSAWN_CIS_INFO.FLDREPID = dbo.tblMsgsOnAir_Type8.fldCBuddyId)
LEFT OUTER JOIN dbo.TBLSAWNGISCOORD
ON (dbo.TBLSAWNGISCOORD.SRV_MAP_LOC = dbo.TBLSAWN_CIS_INFO.SML)
LEFT OUTER JOIN dbo.tblmeterinfo
ON (dbo.tblmeterinfo.fldRepId = dbo.tblMsgsOnAir_Type8.fldRBuddyId)
WHERE dbo.tblMsgsOnAir_Type8.fldRBuddyId IN (SELECT
dbo.tblSAWN_FNPmap.Repid
FROM dbo.tblSAWN_FNPmap)
AND dbo.TBLMETERMAINT.fldmeterid IS NOT NULL
The query below is simple and does what I want, but doesn't get all of the other field. This query only returns 617 records. I would like the above query to return 617 records, but include all of the other information I've selected.
SELECT
dbo.TBLMETERMAINT.fldmeterid AS "Meter_ID_Helped",
MAX(dbo.tblMsgsOnAir_Type8.fldBuddyLinkSigStrength) AS "Max_Sig"
FROM dbo.tblMsgsOnAir_Type8
LEFT OUTER JOIN dbo.TBLMETERMAINT
ON (dbo.TBLMETERMAINT.FLDREPID = dbo.tblMsgsOnAir_Type8.fldCBuddyID)
WHERE dbo.tblMsgsOnAir_Type8.fldRBuddyId IN (SELECT
dbo.tblSAWN_FNPmap.Repid
FROM dbo.tblSAWN_FNPmap)
AND dbo.TBLMETERMAINT.fldmeterid IS NOT NULL
GROUP BY dbo.TBLMETERMAINT.fldmeterid
Probably row_number() to the rescue. You can use it to find the best records in a set, with a grouping by some subset or other. Something like
select *
from ....
where row_number over (partition by id order by fldBuddyLinkSigStrength) = 1
So SQL Server assigns a row number within the groups. Each record will be sub-grouped by id, in this case, and given 1 if it's the best strength, 2 if it's next, etc.
If you are getting duplicates have you tried using SELECT DISTINCT?
Basically how Max works is that it will select the highest value in the group.
So if you have a table:
ID | VALUE
1 | 10
1 | 7
1 | 9
2 | 6
2 | 8
And do
SELECT ID, MAX(VALUE)
FROM TABLE
GROUP BY ID
You'll get the max value per ID
ID | VALUE
1 | 10
2 | 8
If you want to get the Max while not grouping the result then you can do the group in a subselect
SELECT ID, VALUE, MAX_VALUE etc etc
FROM TABLE
JOIN ( SELECT ID, MAX(VALUE) AS MAX_VALUE FROM TABLE GROUP BY ID) as MAX ON MAX.ID = TABLE.ID
Without knowing your table structures in more detail I can't be sure this is the best way, but here's something that should work. Use the 2nd query as the left side of a left join, to pick up the extra columns:
select a.*
from (<your 2nd query>) a
left join dbo.TBLMETERLIST
on (a.FLDREPID = dbo.tblMsgsOnAir_Type8.fldCBuddyId)
left join <next table> ...
and so on. You'll also have to left join on dbo.tblMsgsOnAir_Type8 in order to pick up the columns in that table, so that's one additional left join beyond what your first query does. By the way, it's a good idea to post code here laid out so it's readable; it makes it a lot easier for others to understand.
I am a newbie poster but have spent a lot of time researching answers here. I can't quite figure out how to create a SQL result set using SQL Server 2008 R2 that should probably be using lead/lag from more modern versions. I am trying to aggregate data based on sequencing of one column, but there can be varying numbers of instances in each sequence. The only way I know a sequence has ended is when the next row has a lower sequence number. So it may go 1-2, 1-2-3-4, 1-2-3, and I have to figure out how to make 3 aggregates out of that.
Source data is joined tables that look like this (please help me format):
recordID instanceDate moduleID iResult interactionNum
1356 10/6/15 16:14 1 68 1
1357 10/7/15 16:22 1 100 2
1434 10/9/15 16:58 1 52 1
1435 10/11/15 17:00 1 60 2
1436 10/15/15 16:57 1 100 3
1437 10/15/15 16:59 1 100 4
I need to find a way to separate the first 2 rows from the last 4 rows in this example, based on values in the last column.
What I would love to ultimately get is a result set that looks like this, which averages the iResult column based on the grouping and takes the first instanceDate from the grouping:
instanceDate moduleID iResult
10/6/15 1 84
10/9/15 1 78
I can aggregate to get this result using MIN and AVG if I can just find a way to separate the groups. The data is ordered by instanceDate (please ignore the date formatting here) then interactionNum and the group separation should happen when the query finds a row where the interactionNum is <= than the previous row (will usually start over with '1' but not always, so prefer just to separate on a lower or equal integer value).
Here is the query I have so far (includes the joins that give the above data set):
SELECT
X.*
FROM
(SELECT TOP 100 PERCENT
instanceDate, b.ModuleID, iResult, b.interactionNum
FROM
(firstTable a
INNER JOIN
secondTable b ON b.someID = a.someID)
WHERE
a.someID = 2
AND b.otherID LIKE 'xyz'
AND a.ModuleID = 1
ORDER BY
instanceDate) AS X
OUTER APPLY
(SELECT TOP 1
*
FROM
(SELECT
instanceDate, d.ModuleID, iResult, d.interactionNum
FROM
(firstTable c
INNER JOIN
secondTable d ON d.someID = c.someID)
WHERE
c.someID = 2
AND d.otherID LIKE 'xyz'
AND c.ModuleID = 1
AND d.interactionNum = X.interactionNum
AND c.instanceDate < X.instanceDate) X2
ORDER BY
instanceDate DESC) Y
WHERE
NOT EXISTS (SELECT Y.interactionNum INTERSECT SELECT X.interactionNum)
But this is returning an interim result set like this:
instanceDate ModuleID iResult interactionNum
10/6/15 16:10 1 68 1
10/6/15 16:14 1 100 2
10/15/15 16:57 1 100 3
10/15/15 16:59 1 100 4
and the problem is that interactionNum 3, 4 do not belong in this result set. They would go in the next result set when I loop over this query. How do I keep them out of the result set in this iteration? I need the result set from this query to just include the first two rows, 'seeing' that row 3 of the source data has a lower value for interactionNum than row 2 has.
Not sure what ModuleID was supposed to be used, but I guess you're looking for something like this:
select min (instanceDate), [moduleID], avg([iResult])
from (
select *,row_number() over (partition by [moduleID] order by instanceDate) as RN
from Table1
) X
group by [moduleID], RN - [interactionNum]
The idea here is to create a running number with row_number for each moduleid, and then use the difference between that and InteractionNum as grouping criteria.
Example in SQL Fiddle
Here is my solution, although it should be said, I think #JamesZ answer is cleaner.
I created a new field called newinstance which is 1 wherever your instanceNumber is 1. I then created a rolling sum(newinstance) called rollinginstance to group on.
Change the last select to SELECT * FROM cte2 to show all the fields I added.
IF OBJECT_ID('tempdb..#tmpData') IS NOT NULL
DROP TABLE #tmpData
CREATE TABLE #tmpData (recordID INT, instanceDate DATETIME, moduleID INT, iResult INT, interactionNum INT)
INSERT INTO #tmpData
SELECT 1356,'10/6/15 16:14',1,68,1 UNION
SELECT 1357,'10/7/15 16:22',1,100,2 UNION
SELECT 1434,'10/9/15 16:58',1,52,1 UNION
SELECT 1435,'10/11/15 17:00',1,60,2 UNION
SELECT 1436,'10/15/15 16:57',1,100,3 UNION
SELECT 1437,'10/15/15 16:59',1,100,4
;WITH cte1 AS
(
SELECT *,
CASE WHEN interactionNum=1 THEN 1 ELSE 0 END AS newinstance,
ROW_NUMBER() OVER(ORDER BY recordID) as rowid
FROM #tmpData
), cte2 AS
(
SELECT *,
(select SUM(newinstance) from cte1 b where b.rowid<=a.rowid) as rollinginstance
FROM cte1 a
)
SELECT MIN(instanceDate) AS instanceDate, moduleID, AVG(iResult) AS iResult
FROM cte2
GROUP BY moduleID, rollinginstance
My problem is that out of two tables I need a result set presenting the number of ordered items per PLU and the number of items still on stock.
I cannot do it in ONE stored procedure.
My query presenting the orders.
SELECT
tblOrderDetails.PLU, tblArtikel.Description,
SUM(tblOrderDetails.Pieces) AS Pieces
FROM
tblOrderDetails
INNER JOIN
tblArtikel ON tblOrderDetails.PLU = tblArtikel.PLU
GROUP BY
tblOrderDetails.PLU, tblArtikel.Description
returns as output:
30002 BA4875 3
30012 UK8798 15
My stock is queried with
(SELECT SUM(tblStock.Pieces) AS Ls, tblStock.PLU
from tblStock
GROUP BY tblStock.PLU)
The result should look like:
30002 BA4875 3 0
30012 UK8798 15 8
meaning that for artikelno 30002 there are 3 ordered and 0 on stock
So, how can I combine both queries (resultsets) in one SP?
I always get error
Msg 116
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
I know what the error is, but without the PLU in the stock-query I do not know how to combine both resultsets.
Thanks yr. help
Michael
Can you please try the below
SELECT
tblOrderDetails.PLU, tblArtikel.Description,
SUM(tblOrderDetails.Pieces) AS Pieces
FROM tblOrderDetails
INNER JOIN tblArtikel ON tblOrderDetails.PLU = tblArtikel.PLU
where exists
(
select SUM(tblStock.Pieces) AS Ls, tblStock.PLU from tblStock
where tblArtikel.PLU = tblStock.PLU
GROUP BY tblStock.PLU
having SUM(tblStock.Pieces) > 0
)
GROUP BY tblOrderDetails.PLU, tblArtikel.Description
Please let me know if this helps
I have two tables
table-a
id name
100 asd
101 ass
102 gdd
103 hgf
104 cvd
105 erf
table-b
id filter
100 red
101 blue
100 green
100 yellow
102 black
102 red
103 dark
Table-a is the master table and that have all the id's.but Table two is the one which has 'filter' data.
from these two table I want to find out all those 'id's which does not have minimum 2 filters.
note that table-b does not have all the itemnumbers in table-a, and i want all that itemnumber irrespective of if that is in table-a or table-b.I have tried inner joining these two tables and getting data out but nothing worked.
Select A.ID, A.Name, count(*)
from tableA A
LEFT JOIN tableB B on A.ID = B.ID
Group By A.ID, A.name
having count(*) <= 1
LEFT JOIN gives all records from A and only those in B which match.
The group by ID and name let us count the number of filters found in
each
The having says give me any items with a count less than or
equal to 1. (or less than the minimum 2)
Thus results would be.
101 ass 1
103 hgf 1
104 cvd 0
105 erf 0
select
*
from
table-a a
left join (
select id, count(id) as c from table-b group by id
) v on a.id = v.id
where isnull(v.id, 0) < 2
I think this would work in SQL Server (tested in SQLite and usually the two are fairly compatible when it comes to inline view syntax). But syntax issues aside, inline views can make working with sets easier to visualize.
select TA.id, name
from TA
inner join
(
select id from TA
where not exists (select id from TB where TA.id = TB.id)
UNION
select id from TB
group by id having count(filter) < 2
) as FOO
on TA.id = FOO.id
The default behavior of UNION is to remove duplicates.
The first UNIONed set consists of the ids from table A that have no filter (no counterpart in the filters table B).
The second UNIONed set consists of the ids from the filters table, table B, that have only 1 filter.
We inner join those unioned sets back to Table A to get the entity Name.
