I asked this question before:
How do I bring back an entire range of dates in SQL between two dates, even when there is no data?
but I now need to only select incidents that have a Status of "E" for emergency.
I can't put WHERE status='E' though, because that will stop it returning an entry for every single date.
How can I solve this?
Just add it to the LEFT OUTER JOIN ... ON, since this is a contition for the joined rows as far as I understand the question.
Something like this:
WITH DateRange(date) AS (
SELECT #dateFrom dt
UNION ALL
SELECT DATEADD(dd, 1, date) date FROM DateRange WHERE date < #dateTo
)
SELECT DateRange.date, count(incident.id)
FROM DateRange
LEFT OUTER JOIN incident
ON incident.date >= DateRange.date
AND incident.date < DATEADD(dd, 1, DateRange.date)
AND incident.status = 'E'
GROUP BY DateRange.date
ORDER BY DateRange.date
Like you said in your question, putting the condition in your WHERE clause effectively turns your LEFT JOIN into an INNER JOIN.
You should add this to your LEFT JOIN criteria as the intent is that it's a condition of the join.
So something like table1
LEFT JOIN table2 ON table1.field = table2.field AND table1.status='E'

I am trying to inner join however I keep getting this duplicate pop up where there are two job IDs matching one Invoice ID (inner joined with a middle table that links both).
I want to only get 1 invoice id and summing the total despite 2 job ids matching it.
Basically there is AINVOICEID (table:Invoice ) matching ABINVOICEID (table:INLines) and inside the INLines table, it contains ARJOBID that matches the JOBID in Jobs.
Select distinct sum(totalBASE) as InvoiceTotal,
DATEADD(MONTH, DATEDIFF(MONTH, 0, InvDate), 0)
from (select distinct left(JOBID,5)as JOBID
from jobs
group by JOBID
) jobs
inner join (select distinct ABINVOICEID, left(ARLJOBID,5) as arljobid
from INLines
group by ARLJOBID, ABINVOICEID
) INLines
on left(ARLJOBID,5) = left(JOBID,5)
inner join (select distinct AINVOICEID
, sum(totalBASE) as totalBASE
, InvDate
from Invoice
group by AINVOICEID, InvDate
) Invoice
on AINVOICEID = ABINVOICEID
where left(JOBID ,5)=left(ARLJOBID,5) and AINVOICEID = ABINVOICEID
and InvDate between '05/01/2022' AND '05/31/2022'
group by left(JOBID ,5), DATEADD(MONTH, DATEDIFF(MONTH, 0, InvDate), 0)
It is quite difficult to try and make sense of what you're asking without an example of the output that you're getting and what the expected output is.
However, I think you're wanting something like this:
SELECT I.AINVOICEID, SUM(I.totalBASE) AS totalBASE, InvDate
FROM Invoice I INNER JOIN
(
SELECT L.ABINVOICEID, J.JOBID
FROM INLines L INNER JOIN
Jobs J ON L.ARLJOBID = J.JOBID
GROUP BY L.ABINVOICEID, J.JOBID
) LJ ON I.AINVOICEID = L.ABINVOICEID
WHERE I.InvDate BETWEEN '05/01/2022' AND '05/31/2022'
GROUP BY I.AINVOICEID, InvDate
This is based on what your SQL query which doesn't really look like it needs to JOIN on the INLines or Jobs table because you're getting everything you need from the Invoice table in the SELECT ?
If this isn't what you're after, if you can elaborate a bit more, then the community on here should be able to better assist with your question.
Need help ensuring the below query doesn't return inaccurate results.
select #billed = count(a.[counter]) from [dbo].cxitems a with (nolock)
inner join [dbo].cxitemhist b with (nolock) on a.[counter] = b.cxlink
where b.[eventtype] in ('BILLED','REBILLED')
and b.[datetime] between #begdate and #enddate
The query is "mostly" accurate as is, however there is a slight possibility that cxitemhist table could contain more than 1 "billed" record for given date range. I only need to count item as "Billed" once during given date range.
You can join on a sub query the limits you to one row for each combination of fields used for the join:
select #billed = count(a.[counter])
from [dbo].cxitems a
inner join (
select distinct cxlink
from [dbo].cxitemhist
where [eventtype] in ('BILLED','REBILLED')
and [datetime] between #begdate and #enddate
) b on a.[counter] = b.cxlink
You can also use the APPLY operator instead of a join here, but you'll have to check against your data to see which gives better performance.
If you only need to count records from the cxitems table, that have any corresponding records from the cxitemhist table, you can use the exists clause with a subquery.
select #billed = count(a.[counter]) from [dbo].cxitems a
where exists(select * from [dbo].cxitemhist b
where a.[counter] = b.cxlink
and b.[eventtype] in ('BILLED','REBILLED')
and b.[datetime] between #begdate and #enddate)
Cannot really say how this will affect performance, without specific data, though, but it should be comparably fast with your code.
I have 3 tables that are joined together with this query.
One of them brings me people names , another one brings me their points and the last one brings me date time.
I select the total people score.
Also, there is a column in the 3th tables that brings me the scores' transaction Date Time. My problem is that I want to write a TSQL query with this condition:
Select the transaction date where the people score is 12,000 or more.
In my idea I should use while loop but I do not know the syntax?
This is how I would do it-
SELECT cp.FirstName
, cp.LastName
, SUM(Points) as Score
FROM ClubProfile cp
RIGHT JOIN CardTransaction ct
ON cp.ClubProfileId = ct.ClubProfileId
INNER JOIN Your3rdTable as t3
ON cp.ClubProfileId = t3.ClubProfileId
WHERE CONVERT(VARCHAR, ct.[Date Column], 101) = #your_date_param
GROUP BY
cp.FirstName
, cp.LastName
HAVING SUM(Points) >=12000
Based on your post this should be close to what you need. You need to add that 3rd table and alter this statement accordingly.
SELECT cp.FirstName
, cp.LastName
, SUM(Points) as Score
FROM [fidilio].[dbo].[ClubProfile] cp
RIGHT JOIN (
CardTransaction ct
INNER JOIN CardTransactionLog ctl
ON cp.CardTransactionLogId = ctl.CardTransactionLogId
)
ON cp.ClubProfileId = ct.ClubProfileId
GROUP BY
cp.FirstName
, cp.LastName
HAVING SUM(Points) >=12000
AND ctl.TransactionTimeStamp = #SomeDateTimeVariable
The variable #SomeDateTimeVariable has to come from someplace what is your exact time-frame criteria
I'm pulling my hair out over a subquery that I'm using to avoid about 100 duplicates (out of about 40k records). The records that are duplicated are showing up because they have 2 dates in h2.datecreated for a valid reason, so I can't just scrub the data.
I'm trying to get only the earliest date to return. The first subquery (that starts with "select distinct address_id", with the MIN) works fine on it's own...no duplicates are returned. So it would seem that the left join (or just plain join...I've tried that too) couldn't possibly see the second h2.datecreated, since it doesn't even show up in the subquery. But when I run the whole query, it's returning 2 values for some ipc.mfgid's, one with the h2.datecreated that I want, and the other one that I don't want.
I know it's got to be something really simple, or something that just isn't possible. It really seems like it should work! This is MSSQL. Thanks!

The typical approach to only getting the lowest row is one of the following. You didn't bother to specify what version of SQL Server you're using, what you want to do with ties, and I have little interest to try to work this into your complex query, so I'll show you an abstract simplification for different versions.
SQL Server 2000
SELECT x.grouping_column, x.min_column, x.other_columns ...
FROM dbo.foo AS x
INNER JOIN
(
SELECT grouping_column, min_column = MIN(min_column)
FROM dbo.foo GROUP BY grouping_column
) AS y
ON x.grouping_column = y.grouping_column
AND x.min_column = y.min_column;
SQL Server 2005+
;WITH x AS
(
SELECT grouping_column, min_column, other_columns,
rn = ROW_NUMBER() OVER (ORDER BY min_column)
FROM dbo.foo
)
SELECT grouping_column, min_column, other_columns
FROM x
WHERE rn = 1;
This subqery:
select distinct address_id, equipment_id,
min(datecreated) as datecreated, comment
from history where comment like 'MAC: 5%' group by equipment_id, address_id, comment
Probably will return multiple rows because the comment is not guaranteed to be the same.
Try this instead:
CROSS APPLY (
SELECT TOP 1 H2.DateCreated, H2.Comment -- H2.Equipment_id wasn't used
FROM History H2
WHERE
H2.Comment LIKE 'MAC: 5%'
AND C.Address_ID = H2.Address_ID
ORDER BY DateCreated
) H2
Switch that to OUTER APPLY in case you want rows that don't have a matching desired history entry.
Using SQL 2005: “Taking too much time to execute”
I want to filter the date, the date should not display in holidays, and I am using three tables with Inner Join
When I run the below query, It taking too much time to execute, because I filter the cardeventdate with three table.
Query
SELECT
PERSONID, CardEventDate tmp_cardevent3
WHERE (CardEventDate NOT IN
(SELECT T_CARDEVENT.CARDEVENTDATE
FROM T_PERSON
INNER JOIN T_CARDEVENT ON T_PERSON.PERSONID = T_CARDEVENT.PERSONID
INNER JOIN DUAL_PRO_II_TAS.dbo.T_WORKINOUTTIME ON T_CARDEVENT.CARDEVENTDAY = DUAL_PRO_II_TAS.dbo.T_WORKINOUTTIME.DAYCODE
AND T_PERSON.TACODE = DUAL_PRO_II_TAS.dbo.T_WORKINOUTTIME.TACODE
WHERE (DUAL_PRO_II_TAS.dbo.T_WORKINOUTTIME.HOLIDAY = 'true')
)
)
ORDER BY PERSONID, CardEventDate DESC
For the above mentioned Query, there is any other way to do date filter.
Expecting alternative queries for my query?
I'm pretty sure that it's not the joined tables that is the problem, but rather the "not in" that makes it slow.
Try to use a join instead:
select m.PERSONID, m.CardEventDate
from T_PERSON p
inner join T_CARDEVENT c on p.PERSONID = c.PERSONID
inner join DUAL_PRO_II_TAS.dbo.T_WORKINOUTTIME w
on c.CARDEVENTDAY = w.DAYCODE
and p.TACODE = w.TACODE
and w.HOLIDAY = 'true'
right join tmp_cardevent3 m on m.CardEventDate = c.CardEventDate
where c.CardEventDate is null
order by m.PERSONID, m.CardEventDate desc
(There is a from clause missing from your query, so I don't know what table you are trying to get the data from.)
Edit:
Put tmp_cardevent3 in the correct place.
Have you created indices on all of the columns that you are using to do the joins? In particular, I'd consider indices on PERSONID in T_CARDEVENT, TACODE in both T_PERSON and T_WORKINOUTTIME, and HOLIDAY in T_WORKINOUTTIME.
