I have the below query. The problem is the last column productdesc is returning two records and the query fails because of distinct. Now i need to add one more column in where clause of the select query so that it returns one record. The issue is that the column i need
to add should not be a part of group by clause.
SELECT product_billing_id,
billing_ele,
SUM(round(summary_net_amt_excl_gst/100)) gross,
(SELECT DISTINCT description
FROM RES.tariff_nt
WHERE product_billing_id = aa.product_billing_id
AND billing_ele = aa.billing_ele) productdescr
FROM bil.bill_sum aa
WHERE file_id = 38613 --1=1
AND line_type = 'D'
AND (product_billing_id, billing_ele) IN (SELECT DISTINCT
product_billing_id,
billing_ele
FROM bil.bill_l2 )
AND trans_type_desc <> 'Change'
GROUP BY product_billing_id, billing_ele
I want to modify the select statement to the below way by adding a new filter to the where clause so that it returns one record .
(SELECT DISTINCT description
FROM RRES.tariff_nt
WHERE product_billing_id = aa.product_billing_id
AND billing_ele = aa.billing_ele
AND (rate_structure_start_date <= TO_DATE(aa.p_effective_date,'yyyymmdd')
AND rate_structure_end_date > TO_DATE(aa.p_effective_date,'yyyymmdd'))
) productdescr
The aa.p_effective_date should not be a part of GROUP BY clause. How can I do it? Oracle is the Database.
So there are multiple RES.tariff records for a given product_billing_id/billing_ele, differentiated by the start/end dates
You want the description for the record that encompasses the 'p_effective_date' from bil.bill_sum. The kicker is that you can't (or don't want to) include that in the group by. That suggests you've got multiple rows in bil.bill_sum with different effective dates.
The issue is what do you want to happen if you are summarising up those multiple rows with different dates. Which of those dates do you want to use as the one to get the description.
If it doesn't matter, simply use MIN(aa.p_effective_date), or MAX.
Have you looked into the Oracle analytical functions. This is good link Analytical Functions by Example

I'm collecting data and storing in SQL Server. The table consist of the data shown in the Example Table below. I need to show the amount of time that each field [Fault0-Fault10] is in a fault state. The fault state is represented as a 1 for the fields value.
I have used the following query and got the desired results. However this is for only one field. I need to have the total time for each field in one query. I'm having issues pulling all of the fields into one query.
SELECT
Distinct [Fault0]
,datediff(mi, min(DateAndTime), max(DateAndTime)) TotalTimeInMins
FROM [dbo].[Fault]
Where Fault0 =1
group by [Fault0]
Results
Assuming you want the max() - min(), then you simply need to unpivot the data. Your query can look like:
SELECT v.faultname,
datediff(minute, min(t.DateAndTime), max(t.DateAndTime)) as TotalTimeInMins
FROM [dbo].[Fault] f CROSS APPLY
(VALUES ('fault0', fault0), ('fault1', fault1), . . ., ('fault10', fault10)
) v(faultname, value)
WHERE v.value = 1
GROUP BY v.faultname;
I need to figure out how to eliminate older revisions from my query's results, my database stores orders as 'Q000000' and revisions have an appended '-number'. My query currently is as follows:
SELECT DISTINCT Estimate.EstimateNo
FROM Estimate
INNER JOIN EstimateDetails ON EstimateDetails.EstimateID = Estimate.EstimateID
INNER JOIN EstimateDoorList ON EstimateDoorList.ItemSpecID = EstimateDetails.ItemSpecID
WHERE (Estimate.SalesRepID = '67' OR Estimate.SalesRepID = '61') AND Estimate.EntryDate >= '2017-01-01 00:00:00.000' AND EstimateDoorList.SlabSpecies LIKE '%MDF%'
ORDER BY Estimate.EstimateNo
So for instance, the results would include:
Q120455-10
Q120445-11
Q121675-2
Q122361-1
Q123456
Q123456-1
From this, I need to eliminate 'Q120455-10' because of the presence of '-11' for that order, and 'Q123456' because of the presence of the '-1' revision. I'm struggling greatly with figuring out how to do this, my immediate thought was to use case statements but I'm not sure what is the best way to implement them and how to filter. Thank you in advance, let me know if any more information is needed.
First you have to parse your EstimateNo column into sequence number and revision number using CHARINDEX and SUBSTRING (or STRING_SPLIT in newer versions) and CAST/CONVERT the revision to a numeric type
SELECT
SUBSTRING(Estimate.EstimateNo,0,CHARINDEX('-',Estimate.EstimateNo)) as [EstimateNo],
CAST(SUBSTRING(Estimate.EstimateNo,CHARINDEX('-',Estimate.EstimateNo)+1, LEN(Estimate.EstimateNo)-CHARINDEX('-',Estimate.EstimateNo)+1) as INT) as [EstimateRevision]
FROM
...
You can then use
APPLY - to select TOP 1 row that matches the EstimateNo or
Window function such as ROW_NUMBER to select only records with row number of 1
For example, using a ROW_NUMBER would look something like below:
SELECT
ROW_NUMBER() OVER(PARTITION BY EstimateNo ORDER BY EstimateRevision DESC) AS "LastRevisionForEstimate",
-- rest of the needed columns
FROM
(
-- query above goes here
)
You can then wrap the query above in a simple select with a where predicate filtering out a specific value of LastRevisionForEstimate, for instance
SELECT --needed columns
FROM -- result set above
WHERE LastRevisionForEstimate = 1
Please note that this is to a certain extent, pseudocode, as I do not have your schema and cannot test the query

im looking for a query to fill this condition:
That currently gives us the number of BACs at the entity (which is something we need). The database assigns the BAC IDs consecutively within each accounting entity. So we need to add one more field to the query showing the current highest BAC ID at the entity. And once we have that, just filter the results down to anyplace the number of records doesn't equal the highest ID.
My current query:
select accounting_entity_id, count(bac_id)
from dc.pl_bac_information
group by accounting_entity_id
having count(bac_id) > 1;
Use analytic functions for this:
select bi.*
from (select bi.*, max(bac_id) over (partition by accounting_entity_id) as max_bac_id
from dc.pl_bac_information bi
) bi
where bac_id = max_bac_id;
This assumes you are using Oracle.
SELECT ACCOUNTING_ENTITY_ID
FROM DC.PL_BAC_INFORMATION
HAVING COUNT(BAC_ID) > 1 AND COUNT(BAC_ID) != MAX(BAC_ID)
GROUP BY ACCOUNTING_ENTITY_ID;
I was having a problem getting mulitple sums from multiple tables. Short story, my answer was solved in the "sql sum data from multiple tables" thread on this site. But where it came up short, is that now I'd like to only show sums that are greater than a certain amount. So while I have sub-selects in my select, I think I need to use a HAVING clause to filter the summed amounts that are too low.
Example, using the code specified in the link above (more specifically the answer that the owner has chosen as correct), I would only like to see a query result if SUM(AP2.Value) > 1500. Any thoughts?
If you need to filter on the results of ANY aggregate function, you MUST use a HAVING clause. WHERE is applied at the row level as the DB scans the tables for matching things. HAVING is applied basically immediately before the result set is sent out to the client. At the time WHERE operates, the aggregate function results are not (and cannot) be available, so you have to use a HAVING clause, which is applied after the main query is complete and all aggregate results are available.
So... long story short, yes, you'll need to do
SELECT ...
FROM ...
WHERE ...
HAVING (SUM_AP > 1500)
Note that you can use column aliases in the having clause. In technical terms, having on a query as above works basically exactly the same as wrapping the initial query in another query and applying another WHERE clause on the wrapper:
SELECT *
FROM (
SELECT ...
) AS child
WHERE (SUM_AP > 1500)
You could wrap that query as a subselect and then specify your criteria in the WHERE clause:
SELECT
PROJECT,
SUM_AP,
SUM_INV
FROM (
SELECT
AP1.[PROJECT],
(SELECT SUM(AP2.Value) FROM AP AS AP2 WHERE AP2.PROJECT = AP1.PROJECT) AS SUM_AP,
(SELECT SUM(INV2.Value) FROM INV AS INV2 WHERE INV2.PROJECT = AP1.PROJECT) AS SUM_INV
FROM AP AS AP1
INNER JOIN INV AS INV1 ON
AP1.[PROJECT] = INV1.[PROJECT]
WHERE
AP1.[PROJECT] = 'XXXXX'
GROUP BY
AP1.[PROJECT]
) SQ
WHERE
SQ.SUM_AP > 1500
So I got this statement, which works fine:
SELECT MAX(patient_history_date_bio) AS med_date, medication_name
FROM biological
WHERE patient_id = 12)
GROUP BY medication_name
But, I would like to have the corresponding medication_dose also. So I type this up
SELECT MAX(patient_history_date_bio) AS med_date, medication_name, medication_dose
FROM biological
WHERE (patient_id = 12)
GROUP BY medication_name
But, it gives me an error saying:
"coumn 'biological.medication_dose' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.".
So I try adding medication_dose to the GROUP BY clause, but then it gives me extra rows that I don't want.
I would like to get the latest row for each medication in my table. (The latest row is determined by the max function, getting the latest date).
How do I fix this problem?
Use:
SELECT b.medication_name,
b.patient_history_date_bio AS med_date,
b.medication_dose
FROM BIOLOGICAL b
JOIN (SELECT y.medication_name,
MAX(y.patient_history_date_bio) AS max_date
FROM BIOLOGICAL y
GROUP BY y.medication_name) x ON x.medication_name = b.medication_name
AND x.max_date = b.patient_history_date_bio
WHERE b.patient_id = ?
If you really have to, as one quick workaround, you can apply an aggregate function to your medication_dose such as MAX(medication_dose).
However note that this is normally an indication that you are either building the query incorrectly, or that you need to refactor/normalize your database schema. In your case, it looks like you are tackling the query incorrectly. The correct approach should the one suggested by OMG Poinies in another answer.
You may be interested in checking out the following interesting article which describes the reasons behind this error:
But WHY Must That Column Be Contained in an Aggregate Function or the GROUP BY clause?
You need to put max(medication_dose) in your select. Group by returns a result set that contains distinct values for fields in your group by clause, so apparently you have multiple records that have the same medication_name, but different doses, so you are getting two results.
By putting in max(medication_dose) it will return the maximum dose value for each medication_name. You can use any aggregate function on dose (max, min, avg, sum, etc.)
