I have two separate queries that I'd like to combine but I'm struggling to get the result I'd like. One summarizes all the values in the table and another selects duplicate rows based on the most recent date.
A shortened version of the first query is:
SELECT a.PLANT_NO "PlantNumber",
SUM(CASE WHEN a.REC_STATUS_CD = 'RR' THEN -a.KW_CTR_REDELIVERED_HV
ELSE a.KW_CTR_REDELIVERED_HV END) "KeepWholeResidueMMBtu",
SUM(a.ETH_APPLIED_POP_PCT + a.ISO_APPLIED_POP_PCT +
(CASE WHEN a.PLANT_NO = '002' THEN a.ALTLIQ_APPLIED_POP_PCT ELSE 0 END)
)/100 "NGLPOPPaymentPercent"
FROM GAS_STMT a
INNER JOIN SETTLE_SUMMARY c
ON CASE WHEN SUBSTR(a.TRNX_ID,1,1) = '-'
THEN SUBSTR(a.TRNX_ID, 2, LENGTH(a.TRNX_ID))
ELSE CAST(a.TRNX_ID AS VARCHAR2(100))
END = c.TRNX_ID
AND a.MTR_NO||a.MTR_SFX = c.MTR_NO||c.MTR_SFX
WHERE TO_CHAR(a.PROD_DT, 'YYYY') >= TO_CHAR(ADD_MONTHS(SYSDATE, -36), 'YYYY')
AND a.STATUS_UNIT_TM_CD = 'M'
GROUP BY a.PLANT_NO
ORDER BY a.PLANT_NO
The other query is used to filter out four transactions based on the most recent transaction date.
SELECT a.*
FROM GAS_STMT a,
(SELECT MTR_NO,MTR_SFX,TRNX_ID,REC_STATUS_CD,MAX(ACCT_DT) ACCT_DT
FROM GAS_STMT
WHERE REC_STATUS_CD = 'RR'
GROUP BY MTR_NO, MTR_SFX, TRNX_ID, REC_STATUS_CD
HAVING COUNT(TRNX_ID) > 1) b
WHERE a.MTR_NO = b.MTR_NO
AND a.TRNX_ID = b.TRNX_ID AND a.REC_STATUS_CD = b.REC_STATUS_CD
AND a.ACCT_DT = b.ACCT_DT
I would think that I could use where NOT IN or NOT EXISTS to have the first query sum everything except for those four records excluded in the second query.
Using EXISTS I get the same result as the first query by itself and using NOT EXISTS I get no results. When I use IN I get a sum of the excluded records which is the opposite of what I want.
Is there a good way to do this in PL/SQL? I'm confused that I'm not getting any records for the NOT EXISTS query.
Example of first query results:
Plant_No - Sum
002 - 100
450 - 50
500 - 50
Example of second query results:
Trnx_ID - Plant_no - KW_CTR_REDELIVERED_HV
1234 - 002 - -.99
1235 - 002 - -.99
Intended result:
Plant_No - Sum
002 - 98.02
450 - 50
500 - 50
If you want to exclude the records returned by the second query, try:
SELECT a.PLANT_NO "PlantNumber",
SUM(CASE WHEN a.REC_STATUS_CD = 'RR' THEN -a.KW_CTR_REDELIVERED_HV
ELSE a.KW_CTR_REDELIVERED_HV END) "KeepWholeResidueMMBtu",
SUM(a.ETH_APPLIED_POP_PCT + a.ISO_APPLIED_POP_PCT +
(CASE WHEN a.PLANT_NO = '002' THEN a.ALTLIQ_APPLIED_POP_PCT ELSE 0 END)
)/100 "NGLPOPPaymentPercent"
FROM GAS_STMT a
INNER JOIN SETTLE_SUMMARY c
ON CASE WHEN SUBSTR(a.TRNX_ID,1,1) = '-'
THEN SUBSTR(a.TRNX_ID, 2, LENGTH(a.TRNX_ID))
ELSE CAST(a.TRNX_ID AS VARCHAR2(100))
END = c.TRNX_ID
AND a.MTR_NO||a.MTR_SFX = c.MTR_NO||c.MTR_SFX
LEFT JOIN (SELECT MTR_NO,MTR_SFX,TRNX_ID,REC_STATUS_CD,MAX(ACCT_DT) ACCT_DT
FROM GAS_STMT
WHERE REC_STATUS_CD = 'RR'
GROUP BY MTR_NO, MTR_SFX, TRNX_ID, REC_STATUS_CD
HAVING COUNT(TRNX_ID) > 1) b
ON a.MTR_NO = b.MTR_NO
AND a.TRNX_ID = b.TRNX_ID
AND a.REC_STATUS_CD = b.REC_STATUS_CD
AND a.ACCT_DT = b.ACCT_DT
WHERE TO_CHAR(a.PROD_DT, 'YYYY') >= TO_CHAR(ADD_MONTHS(SYSDATE, -36), 'YYYY')
AND a.STATUS_UNIT_TM_CD = 'M'
AND b.MTR_NO IS NULL
GROUP BY a.PLANT_NO
ORDER BY a.PLANT_NO
Join b from the second query on to the first query the same way that the second query does it i.e.
inner join (SELECT MTR_NO,MTR_SFX,TRNX_ID,REC_STATUS_CD,MAX(ACCT_DT) ACCT_DT
FROM GAS_STMT
WHERE REC_STATUS_CD = 'RR'
GROUP BY MTR_NO, MTR_SFX, TRNX_ID, REC_STATUS_CD
HAVING COUNT(TRNX_ID) > 1) b
on a.MTR_NO = b.MTR_NO
AND a.TRNX_ID = b.TRNX_ID AND a.REC_STATUS_CD = b.REC_STATUS_CD
AND a.ACCT_DT = b.ACCT_DT
that way you get everything from the first query but only from the rows that would show up on the second query

This question already has an answer here:
How to use an Alias in a Calculation for Another Field
(1 answer)
Closed 3 years ago.
In my query below I am counting occurrences in a table based on the Status column. I also want to perform calculations based on the counts I am returning. For example, let's say I want to add 100 to the Snoozed value... how do I do this? Below is what I thought would do it:
SELECT
pu.ID Id, pu.Name Name,
COUNT(*) LeadCount,
SUM(CASE WHEN Status = 'Working' THEN 1 ELSE 0 END) AS Working,
SUM(CASE WHEN Status = 'Uninterested' THEN 1 ELSE 0 END) AS Uninterested,
SUM(CASE WHEN Status = 'Converted' THEN 1 ELSE 0 END) AS Converted,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END) AS Snoozed,
Snoozed + 100 AS Test
FROM
Prospects p
INNER JOIN
ProspectsUsers pu on p.OwnerId = pu.SalesForceId
WHERE
p.Store = '108'
GROUP BY
pu.Name, pu.Id
ORDER BY
Name
I get this error:
Invalid column name 'Snoozed'.
How can I take the value of the previous SUM statement, add 100 to it, and return it as another column? What I was aiming for is an additional column labeled Test that has the Snooze count + 100.
You can't use one column to create another column in the same way that you are attempting. You have 2 options:
Do the full calculation (as #forpas has mentioned in the comments above)
Use a temp table or table variable to store the data, this way you can get the first 5 columns, and then you can add the last column or you can select from the temp table and do the last column calculations from there.
You can not use an alias as a column reference in the same query. The correct script is:
SELECT
pu.ID Id, pu.Name Name,
COUNT(*) LeadCount,
SUM(CASE WHEN Status = 'Working' THEN 1 ELSE 0 END) AS Working,
SUM(CASE WHEN Status = 'Uninterested' THEN 1 ELSE 0 END) AS Uninterested,
SUM(CASE WHEN Status = 'Converted' THEN 1 ELSE 0 END) AS Converted,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END)+100 AS Snoozed
FROM
Prospects p
INNER JOIN
ProspectsUsers pu on p.OwnerId = pu.SalesForceId
WHERE
p.Store = '108'
GROUP BY
pu.Name, pu.Id
ORDER BY
Name
MSSQL does not allow you to reference fields (or aliases) in the SELECT statement from within the same SELECT statement.
To work around this:
Use a CTE. Define the columns you want to select from in the CTE, and then select from them outside the CTE.
;WITH OurCte AS (
SELECT
5 + 5 - 3 AS OurInitialValue
)
SELECT
OurInitialValue / 2 AS OurFinalValue
FROM OurCte
Use a temp table. This is very similar in functionality to using a CTE, however, it does have different performance implications.
SELECT
5 + 5 - 3 AS OurInitialValue
INTO #OurTempTable
SELECT
OurInitialValue / 2 AS OurFinalValue
FROM #OurTempTable
Use a subquery. This tends to be more difficult to read than the above. I'm not certain what the advantage is to this - maybe someone in the comments can enlighten me.
SELECT
5 + 5 - 3 AS OurInitialValue
FROM (
SELECT
OurInitialValue / 2 AS OurFinalValue
) OurSubquery
Embed your calculations. opinion warning This is really sloppy, and not a great approach as you end up having to duplicate code, and can easily throw columns out-of-sync if you update the calculation in one location and not the other.
SELECT
5 + 5 - 3 AS OurInitialValue
, (5 + 5 - 3) / 2 AS OurFinalValue
You can't use a column alias in the same select. The column alias do not precedence / sequence; they are all created after the eval of the select result, just before group by and order by.
You must repeat code :
SELECT
pu.ID Id,pu.Name Name,
COUNT(*) LeadCount,
SUM(CASE WHEN Status = 'Working' THEN 1 ELSE 0 END) AS Working,
SUM(CASE WHEN Status = 'Uninterested' THEN 1 ELSE 0 END) AS Uninterested,
SUM(CASE WHEN Status = 'Converted' THEN 1 ELSE 0 END) AS Converted,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END) AS Snoozed,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END)+ 100 AS Test
FROM
Prospects p
INNER JOIN
ProspectsUsers pu on p.OwnerId = pu.SalesForceId
WHERE
p.Store = '108'
GROUP BY
pu.Name, pu.Id
ORDER BY
Name
If you don't want to repeat the code, use a subquery
SELECT
ID, Name, LeadCount, Working, Uninterested,Converted, Snoozed, Snoozed +100 AS test
FROM
(SELECT
pu.ID Id,pu.Name Name,
COUNT(*) LeadCount,
SUM(CASE WHEN Status = 'Working' THEN 1 ELSE 0 END) AS Working,
SUM(CASE WHEN Status = 'Uninterested' THEN 1 ELSE 0 END) AS Uninterested,
SUM(CASE WHEN Status = 'Converted' THEN 1 ELSE 0 END) AS Converted,
SUM(CASE WHEN SnoozedId > 0 THEN 1 ELSE 0 END) AS Snoozed
FROM Prospects p
INNER JOIN ProspectsUsers pu on p.OwnerId = pu.SalesForceId
WHERE p.Store = '108'
GROUP BY pu.Name, pu.Id) t
ORDER BY Name

Before starting, thank you for your help.
My problem is: I have a table, for example, activity_records, that has a date column and a activity_id column.
I want to select only those dates that, for example, have the activity_id value of 1 but do not have the value of 2 in any of the other records having the same date.
I have tried multi-select queries and all that.
One method uses not exists:
select ar.*
from activity_records ar
where ar.activity_id = 1 and
not exists (select 1
from activity_records ar2
where r2.date = ar.date and ar2.activity_id = 2
);
Because you only want dates, an alternative is group by:
select ar.date
from activity_records ar
group by ar.date
having sum(case when ar.activity_id = 1 then 1 else 0 end) > 0 and
sum(case when ar.activity_id = 2 then 1 else 0 end) = 0;
Or, most simply for this particular case:
select ar.date
from activity_records ar
where ar.activity_id in (1, 2)
group by ar.date
having max(ar.activity_id) = 1 ;
SELECT [date] FROM [activity_records] WHERE [activity_id] = 1
EXCEPT
SELECT [date] FROM [activity_records] WHERE [activity_id] = 2
See also WHERE NOT EXISTS and APPLY for more complicated scenarios.
Another way is to take only those dates with one distinct activity_id against it and then filtering those dates with activity_id = 1 by a self join.
SELECT DISTINCT B.DATE
FROM
(SELECT DATE, COUNT(DISTINCT ACTIVITY) AS COUNT_ACTIVITIES
FROM YOUR_TABLE
GROUP BY DATE
HAVING COUNT(DISTINCT ACTIVITY) = 1) A
INNER JOIN
YOUR_TABLE B
ON A.DATE = B.DATE
AND B.ACTIVITY_ID = 1;
One method using not in :
select ar.* from activity_records ar where ar.activity_id = 1 and ar.date not in (select ar2.date from activity_records ar2 where ar2.activity_id = 2 );
I would like to SUM() while also using a WHERE but when there are no records found for a certain ID I would like it to return NULL instead of just not returning anything.
Initial Code:
SELECT
ID,
SUM(CASE WHEN EVENTS = 3 THEN 1 ELSE 0 END)
FROM Events_ID
WHERE
YEAR = 2012
GROUP BY ID
This would not return an ID if there were no events for it in 2012.
I then changed it to the following that appears to work but is around 100x slower!
SELECT
ID,
(SELECT
SUM(CASE WHEN EVENTS = 3 THEN 1 ELSE 0 END)
FROM EVENTS_ID r WHERE r.ID = t.ID AND r.YEAR = 2012)
FROM (SELECT * FROM Events_ID GROUP BY ID) as t;
Is there anyway to get the output of the second query nearer to the speed of the first?
Is this what you want?
SELECT ID,
SUM(CASE WHEN EVENTS = 3 AND YEAR = 2012 THEN 1 END)
FROM Events_ID
GROUP BY ID;
This will return all ids, with a NULL as a second value if no events match both conditions.
I have a problem, I need to calculate the percentage between 2 different columns. Unfortunately I can't get it to work and when I run this all I get is "Invalid column name 'CountOfPlannedVisits'" & "Invalid column name 'CountOfPlannedVisitsClosed'"
SELECT Count(*) As CountOfPlannedVisits, MAX(datename(month, dbo.tblVisit.DateConfirmed)) AS MonthName,
SUM(CASE WHEN tblVisit.VisitTypeRef <> '5' THEN 1 ELSE 0 END) AS CountOfPlannedVisitsClosed, CAST(100.0 * SUM("CountOfPlannedVisits") / SUM(CountOfPlannedVisitsClosed) AS Decimal(5,2) ) As OverallAttendance
FROM dbo.tblContract INNER JOIN
dbo.tblCustomer ON dbo.tblContract.CustomerRef = dbo.tblCustomer.CustomerID INNER JOIN
dbo.tblContractSite ON dbo.tblContract.ContractID = dbo.tblContractSite.ContractRef INNER JOIN
dbo.tblVisit ON dbo.tblContractSite.CardNumber = dbo.tblVisit.CardNumber
WHERE (tblCustomer.CustomerNumber = '08434')
AND (tblVisit.Routine = '1')
AND year(tblVisit.DateConfirmed) = Year('2013')--#DateYear)
AND dbo.IsOnHoldEx(tblContract.OnHold, tblContractSite.OnHold, tblContract.OnHoldStartDate, tblContract.OnHoldEndDate, tblContractSite.OnHoldStartDate, tblContractSite.OnHoldEndDate) = 0
AND tblVisit.Deleted = 0 -- make sure we dont pull through deleted visits
AND (tblContractSite.DateInactive is NULL or tblContractSite.DateInactive > GetDate())
GROUP BY month(dbo.tblVisit.DateConfirmed)
Any help would be greatly appreciated as I'm not really sure where to go from here!
Thanks
You can only reference a column alias (like CountOfPlannedVisits in your case) in the order by clause. Anywhere else you have to repeat the expression or use a subquery table, something like :
select CountOfPlannedVisits,
CountOfPlannedVisitsClosed,
100 * CountOfPlannedVisits / CountOfPlannedVisitsClosed, ...
from (
select some_expression as CountOfPlannedVisits ,
some_other_expression as CountOfPlannedVisitsClosed
....
) a_table
....
How can i get the distinct dates in a table where R.TypeofDayID = 2 and it should not include dates with R.TypeofDayID = 1
I can get all the distinct dates for R.TypeofDayID = 2 using the below query but i am not sure how i can add a condition to get dates where TypeofDayID = 2 and the date should not have TypeofDayID = 1 in any row.
Select count(distinct(R.Date)) from RepInfo R
where R.TypeofDayID = 2 and Month(R.Date) = 2 and Year(R.Date) = 2013
I hope i am clear. This is in SQL Server 2005. Thank you in advance!
Select R.Date, count(*) as cnt
from RepInfo R
where Month(R.Date) = 2 and Year(R.Date) = 2013
group by R.Date
having sum(case when TypeofDayID <> 2 then 1 else 0 end) = 0
Why are you using a COUNT() function in your select statement if you want the the output to be a list of distinct dates? Would you get your desired result from changing your select to something like this:
Select distinct(R.Date)
