Hi I am trying to return the record with the highest date for each inidivdual in a database. The fields I am working with are {Entity.TaxID} which is the unique identifer for each individual. Each individual has multiple records and I am trying to show only the record with the largest {Tran.IssueDate}.
Does anyone know how to return only the largest {Tran.IssueDate} for a group of {Entity.TaxID}? Thanks
Create a group with {Entity.TaxID}.
Place the {Tran.IssueDate} in detail.
In group footer take Maximum {Tran.IssueDate}
To take maximum.
Right click on `{Tran.IssueDate}` and go to `Insert summary`... there take maximum.

I have a Crystal Report with all my records grouped by customer. I also have an SQL command that checks whether the customer has had services, if so then 1 else 0.
When I place this into my report in the group header/footer then as expected I get a 1 or 0 depending on whether the customer has had a service in the time frame or not. All good so far..
Now the problem is here, I need to count the number of groups that have a 1 and place this total in the report header. Whenever I use a sum or a count though I get really high numbers, because even though its showing a 1 or 0, it's instead counting the number of details in the group.
Any thoughts on how to best approach this?
Create a Running total to SUM that formula.
Set the evaluation to once for each group change.
I am trying to automatically count the unique occurrences of a string saved in the table. Currently I have a count of a string but only when a user selects the string and it gives every record the same count value.
For example
Below is a image of my current table:
From the image you can see that there is a Requirement column and a count column. I have got it to the point were when the user would select a requirement record (each requirement record has a link) it would insert the requirement text into a requirement item called 'P33_REQUIREMENT' so the count can have a value to compare to.
This is the SQL that I have at current:
SELECT (SELECT COUNT(*)
FROM DIA_ASSOCIATED_QMS_DOCUMENTS
WHERE REQUIREMENT = :P33_REQUIREMENT
group by REQUIREMENT
) AS COUNT,
DPD.DIA_SELECTED,
DPD.Q_NUMBER_SELECTED,
DPD.SECTION_SELECTED,
DPD.ASSIGNED_TO_PERSON,
DAQD.REFERENCE,
DAQD.REQUIREMENT,
DAQD.PROGRESS,
DAQD.ACTION_DUE_DATE,
DAQD.COMPLETION_DATE,
DAQD.DIA_REF,
DA.DIA,
DA.ORG_RISK_SCORE
FROM DIA_PROPOSED_DETAIL DPD,
DIA_ASSOCIATED_QMS_DOCUMENTS DAQD,
DIA_ASSESSMENTS DA
WHERE DPD.DIA_SELECTED = DAQD.DIA_REF
AND DPD.DIA_SELECTED = DA.DIA
This is the sql used to make the table in the image.
This issue with this is, it is giving every record the same count when the user selects a requirement value. I can kind of fix this by also adding in AND DIA_SELECTED = :P33_DIA into the where clause of the count. DIA_SELECTED being the first column in the table and :P33_DIA being the item that stores the DIA ref number relating to the record chosen.
The output of this looks like:
As you can see there is only one count. Still doesn't fix the entire issue but a bit better.
So to sum up is there a way to have the count, count the occurrences individually and insert them in the requirements that are the same. So if there are three tests like in the images there would be a '3' in the count column where requirement = 'test', and if there is one record with 'test the system' there would be a '1' in the count column.
Also for more context I wont know what the user will input into the requirement so I can't compare to pre-determined strings.
I'm new to stack overflow I am hoping I have explained enough and its not too confusing.
The following extract:
SELECT (SELECT COUNT(*)
FROM DIA_ASSOCIATED_QMS_DOCUMENTS
WHERE REQUIREMENT = :P33_REQUIREMENT group by REQUIREMENT ) AS COUNT
Could be replaced by
SELECT (SELECT COUNT(*)
FROM DIA_ASSOCIATED_QMS_DOCUMENTS
WHERE REQUIREMENT = DAQD.REQUIREMENT ) AS COUNT
Which would give you - for each line, the number of requirements that are identical.
I'm not completely certain it is what you are after, but if it isn't, it should give you some ideas on how to progress (or allow you to indicate where I failed to understand your request)
I'm currently writing a stored procedure for my client to populate some tables that will be used to generate SSRS reports later on. Some of the data is based on specific stock formulas that are run on each of their clients' quarterly data (sent to them by their clients). The other part of the data is generated by comparing those results against those from other, similar sized clients. One of the things that they want tracked in their reports is the average of the top 25% of formula results for that particular comparison group.
To give a better picture of it, imagine the following fields that I have in a temp table:
FormulaID int
Value decimal (18,6)
I want to do the following: Given a specific FormulaID return the average of the top 25% of Value.
I know how to take an average in SQL, but I don't know how to do it against only the top 25% of a specific group.
How would I write this query?
I guess you can do something like this...
SELECT AVG(Q.ColA) Avg25Prec
FROM (
SELECT TOP 25 Percent ColA
FROM Table_Name
ORDER BY SomeCOlumn
) Q
Here's what I did, given the table shown above:
select AVG(t.Value)
from (select top 25 percent Value
from #TempGroupTable
where FormulaID = #PassedInFormulaID
order by Value desc) as t
The desc must be there, because the percent command will not actually do comparisons. It will just simply grab the first x number of records, with x being equal to 25% of the count of records it's querying. Therefore, the order by Value desc line then will grab the top 25% records which have the highest Value, and then sends that info to be averaged.
As a side note to all of this, this also means that if you wanted to grab the bottom 25% instead, or if your formula results are like a golf score (i.e. lowest is the best), all you would need to do is remove the desc part and you would be good to go.
I am writing reports using Report Builder 3, and I need some help with an sql query to get unique values.
Using the following sample data:
I need to be able to get one single value for feeBudRec returned for each feeRef. The value of each feeBudRec is always the same for each individual feeRef (eg for every data row for feeRef LR01 will have a feeBudRec of 1177).
The reason why I need to get a single feeBudRec value for each feeRef is that I need to be able to total the feeBudRec value for each feeRef in a feePin (eg for feePin LEE, I need to total the feeBudRec values for LR01 and PS01, which should be 1177 + 1957 to get a total of 3134; but if I don't have unique values for feeBudRec, it will add the values for each row, which would bring back a total of 11756 for the 8 LEE rows).
My experience with writing SQL queries is very limited, but from searching the internet, it looks like I'll need to put in a subquery into my SQL query in order to get a single unique feeBudRec figure for each feeRef, and that a subquery that gets a minimum feeBudRec value for each feeRef should work for me.
Based on examples I've found, I think the following subquery should work:
SELECT a.feeRef, a.feeBudRec
FROM (
SELECT uvw_EarnerInfo.feeRef, Min(uvw_EarnerInfo.feeBudRec) as AvailableTime
FROM uvw_EarnerInfo
GROUP BY
uvw_EarnerInfo.feeRef
) as x INNER JOIN uvw_EarnerInfo as a ON a.feeRef = x.feeRef AND a.feeBudRec = x.AvailableTime;
The problem is that I have no idea how to insert that subquery into the query I'm using to produce the report (as follows):
SELECT
uvw_EarnerInfo.feeRef
,uvw_EarnerInfo.PersonName
,uvw_EarnerInfo.PersonSurname
,uvw_EarnerInfo.feePin
,uvw_RB_TimeLedger.TimeDate
,uvw_RB_TimeLedger.matRef
,uvw_RB_TimeLedger.TimeTypeCode
,uvw_RB_TimeLedger.TimeCharge
,uvw_RB_TimeLedger.TimeElapsed
,uvw_WoffTimeByTime.WoffMins
,uvw_WoffTimeByTime.WoffCharge
,uvw_EarnerInfo.feeBudRec
,uvw_EarnerInfo.personOccupation
FROM
uvw_RB_TimeLedger
LEFT OUTER JOIN uvw_WoffTimeByTime
ON uvw_RB_TimeLedger.TimeId = uvw_WoffTimeByTime.TimeId
RIGHT OUTER JOIN uvw_EarnerInfo
ON uvw_EarnerInfo.feeRef = uvw_RB_TimeLedger.feeRef
WHERE
uvw_RB_TimeLedger.TimeDate >= #TimeDate
AND uvw_RB_TimeLedger.TimeDate <= #TimeDate2
If that subquery will get the correct results, can anyone please help me with inserting it into my report query. Otherwise, can anyone let me know what I will need to do to get a unique feeBudRec value for each feeRef?
Depends on the exact schema, but assuming the uvw_EarnerInfo lists the Pin, Ref, and Rec without duplicates, try adding an extra column (after personOccupation) on the end of your query such as :
feeBudRecSum = (Select SUM(FeeBudRec) From uvw_EarnerInfo x
where x.feePin = uvw_EarnerInfo.feePin
Group By x.FeePin)
Note that you would not Sum these values in your report. This column should have the total you are looking for.
The key to Report Builder is to get your query correct from the offset and let the wizard then structure your report for you. It takes all the hard work out of structuring your report manually.
I haven't used Report Builder for a while now but in the query builder of the report displaying the graphical representation of your query you should be able to drag and drop columns in and out of the query set. Dragging a column upwards and out of the box (showing your columns) would have the effect of causing your report to break on this column.
If you restructure this way you will probably have to run the report generator again to regenerate the report and restructure it.
Once you are happy with the structure you can then begin to add the summary columns.
I'm developing an online gallery with voting and have a separate table for pictures and votes (for every vote I'm storing the ID of the picture and the ID of the voter). The tables related like this: PICTURE <--(1:n, using VOTE.picture_id)-- VOTE. I would like to query the pictures table and sort the output by votes number. This is what I do:
SELECT
picture.votes_number,
picture.creation_date,
picture.author_id,
picture.author_nickname,
picture.id,
picture.url,
picture.name,
picture.width,
picture.height,
coalesce(anon_1."totalVotes", 0)
FROM picture
LEFT OUTER JOIN
(SELECT
vote.picture_id as pid,
count(*) AS "totalVotes"
FROM vote
WHERE vote.device_id = <this is the query parameter> GROUP BY pid) AS anon_1
ON picture.id = anon_1.pid
ORDER BY picture.votes_number DESC
LIMIT 10
OFFSET 0
OFFSET is different for different pages, of course.
However, there are pictures with the same ID that are displayed on the different pages. I guess the reason is the sorting, but can't construct any better query, which will not allow duplicates. Could anybody give me a hint?
Thanks in advance!
Do you execute one query per page to display? If yes, I suspect that the database doesn't guarantee a consitent order for items with the same number of votes. So first query may return { item 1, item 2 } and a 2nd query may return { item 2, item 1} if both items have same number of votes. If the items are actually items 10 and 11, then the same item may appear on page 1 and then on page 2.
I had such a problem once. If that's also your case, append an extra clause to the order by to ensure a consistent ordering of items with same vote number, e.g.:
ORDER BY picture.vote, picture.ID
The simples explanation is that you had some data added or some votes occured when you was looking at different pages.
I am sure if you would sorte by ID or creation_date this issue would go away.
I.e. there is no issue with your code
in my case this problem was due to the Null value in the Order By clause, i solved this by adding another Unique ID field in Order By Clause along with other field.
