My report shows only the latest diagnosis per patient based on their date_of_diagnosis - all other records are suppressed:
I summarize by diagnosis and age group in a crosstab. Crosstabs evaluate before printing, so any attempts to suppress, share variables, or summarize happen after the crosstab populates. This means Total in Each Age Group is correct, because each patient only has one age - but if a patient has more than one diagnosis, even if they're suppressed, they get counted multiple times:
I absolutely must use a crosstab for this due to the large number of diagnoses and age groups involved. How can I get the crosstab to ignore suppressed records? Or if I need to use a custom SQL Command table, how can I rewrite the existing SQL to ignore obsolete records?
Crystal's auto-generated SQL (through ODBC):
SELECT "Codes"."diagnosis_code",
"Codes"."diagnosis_value",
"Codes"."PATID",
"Codes"."FACILITY",
"Codes"."EPISODE_NUMBER",
"Record"."date_of_diagnosis"
FROM "SYSTEM"."Codes" "Codes",
"SYSTEM"."Entry" "Entry",
"SYSTEM"."Record" "Record"
WHERE "Codes"."DiagnosisEntry"="Entry"."ID" AND
"Codes"."EPISODE_NUMBER"="Entry"."EPISODE_NUMBER" AND
"Codes"."FACILITY"="Entry"."FACILITY" AND
"Codes"."PATID"="Entry"."PATID" AND
"Entry"."DiagnosisRecord"="Record"."ID" AND
"Entry"."EPISODE_NUMBER"="Record"."EPISODE_NUMBER" AND
"Entry"."FACILITY"="Record"."FACILITY" AND
"Entry"."PATID"="Record"."PATID"
You need only the latest diagnosis among a set of diagnoses. So I would suggest:
SELECT "Codes"."PATID",
"Codes"."diagnosis_code",
"Codes"."diagnosis_value",
"Codes"."FACILITY",
"Codes"."EPISODE_NUMBER",
"Record"."date_of_diagnosis"
FROM "SYSTEM"."Codes" "Codes",
"SYSTEM"."Entry" "Entry",
"SYSTEM"."Record" "Record"
WHERE "Codes"."DiagnosisEntry"="Entry"."ID" AND
"Codes"."EPISODE_NUMBER"="Entry"."EPISODE_NUMBER" AND
"Codes"."FACILITY"="Entry"."FACILITY" AND
"Codes"."PATID"="Entry"."PATID" AND
"Entry"."DiagnosisRecord"="Record"."ID" AND
"Entry"."EPISODE_NUMBER"="Record"."EPISODE_NUMBER" AND
"Entry"."FACILITY"="Record"."FACILITY" AND
"Entry"."PATID"="Record"."PATID"
AND "Entry"."date_of_diagnosis" = (SELECT MAX("date_of_diagnosis") FROM
"DiagonsisRecord" "A" WHERE "A"."DiagnosisRecord"="Entry"."DiagnosisRecord" )
This should get the maximum Date_of_Diagnosis for each patient and pass the filter parameter to get the last diagnosis of that patient.
Building off of Muffaddal Shakir's answer, I was able to write this query to perform the correct filter:
SELECT "Codes"."PATID",
"Codes"."diagnosis_code",
"Codes"."diagnosis_value",
"Codes"."FACILITY",
"Codes"."EPISODE_NUMBER",
"Record"."date_of_diagnosis"
FROM "SYSTEM"."codes" "Codes",
"SYSTEM"."entry" "Entry",
"SYSTEM"."record" "Record"
WHERE "Codes"."DiagnosisEntry"="Entry"."ID" AND
"Codes"."EPISODE_NUMBER"="Entry"."EPISODE_NUMBER" AND
"Codes"."FACILITY"="Entry"."FACILITY" AND
"Codes"."PATID"="Entry"."PATID" AND
"Entry"."DiagnosisRecord"="Record"."ID" AND
"Entry"."EPISODE_NUMBER"="Record"."EPISODE_NUMBER" AND
"Entry"."FACILITY"="Record"."FACILITY" AND
"Entry"."PATID"="Record"."PATID"
AND "Record"."date_of_diagnosis" = (
SELECT MAX("Record2"."date_of_diagnosis")
FROM "SYSTEM"."entry" "Entry2",
"SYSTEM"."record" "Record2"
WHERE "Entry2"."DiagnosisRecord"="Record2"."ID" AND
"Entry2"."EPISODE_NUMBER"="Record2"."EPISODE_NUMBER" AND
"Entry2"."FACILITY"="Record2"."FACILITY" AND
"Entry2"."PATID"="Record2"."PATID" AND
"Record"."PATID"="Record2"."PATID"
)
The key differences being:
The subquery uses unique aliases from the main query.
The last line "Record"."PATID"="Record2"."PATID" - Without this, the query only pulls back one diagnosis (the latest one in the whole system.) But now it checks for the latest diagnosis per person.

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 have made a simplified example to illustrate the question i'm trying to ask here. In my example i have sales orders and each sales order has multiple lines, i group by Sales Order Number, then by Sales Order Line (row groups)
I have found Group Filters very useful/flexible in filtering report data in specific areas of a table, so in my example i filter the SOLine group to exclude the SO line if it equals 3.
Then, i want to have a group aggregate for the entire SO, to tell me a count of the SO lines within it. Unfortunately when doing COUNT() expression from a textbox within the Sales Order Number group scope it counts all the lines, including the SO Line 3, whereas i want it to take into consideration the line filtered out from its child group.
Below is a screenshot of my tablix and grouping:
On the SOLine group i have the following filter:
And below is the output i get when previewing the report:
I want that count to evaluate to 4, but i ideally want to keep using groups as i've found they are much more efficient than using SUM(IIF) which completely slowed down my actual report which has thousands of rows.
If this is not possible, please give all best alternatives i could use.
Many thanks.

I am looking for a way to search for a certain number of rows as a quality check. For example, we have tables that have a certain set of results that are needed.
Here is a quick table for an example:
ID: Name: Result: Reportable:
ONE A 10 X
TWO B 12 X
THREE C 1
FOUR D 18 X
FOUR(redo) D 11 X
So we are looking to double check results as there are people who accidentally report results multiple times (as in the case with ID FOUR). We have used having counts but we need the numbers to be specific and need a query to verify that number is satisfied.
In the table above we only want IDs ONE, TWO, and FOUR, however we have 4 results (one extra). Currently we have our check showing the count needed (ie 3) and the current result count (4) to show the mismatch but want a query to easily only show the result needed. We would need the redo result most of the time so we have set it so we take the latest date, but it doesn't help filter how many rows or results. I apologize if anything is confusing and I am not able to share the SQL query that we have currently. It's my first time posting so if I need to clarify anything please let me know as this seems to be very complicated. Thank you for your time.
EDIT: The details
We have one table (Table A) letting us know which results are reportable. The ones that are reportable go into another table (Table B). We have had issues in which people have made too many results reportable which overpopulates the Table B. Our old query had a count in Table B, but due to mistakes in people placing multiple reportables, samples which had many redos seem to be finished as they were all placed and met the count in Table B.
So now by using the Table A that helps tell us how many are Reportable, we want this to double check that the samples are indeed ready.
As I understand the question, you want ids that have multiple reportables. Assuming you really mean name, then:
select name
from t
where reportable = 'X'
group by name
having count(*) >= 2;
I have a query that returns a dataset with UserID, CourseID, Course Completion date, Course Registration Date and Status (successful, not attempted, not finished).
However people are allowed to do a course multiple times.
For 1 report I need to get a unique recordset (based upon the Combination UserID and CourseID) back according to the following rules:
If a course is completed successfully by a learner take only that value
If a course is completed successfully by a learner multiple times, take the first completion date.
if a course not completed successfully by a learner take the last registration date.
I know how to create a query that only returns unique (Distinct) values, but not how to do it with a set of rules.
I see that this is a bit older. I don't know if this directly answers your question because I couldn't think of a way to write a single query to do this. I did however come up with a solution that I tested myself.
Using 3 tables and 4 queries, I think that I have produced the results you're looking for.
The first query I wrote was to get the "First Completed" dates. Since if a person only completes a course once, that is their first completion, this actually means your criteria 1 and 2 are identical.
I did this by grouping on the UserID and the CourseID and then taking the aggregate MIN of the CourseCompleteionDate where the Status is equal to 1.
SELECT tblRegistrations.UserID, tblRegistrations.CourseID, Min(tblRegistrations.CourseCompletionDate) AS FirstCompleted
FROM tblRegistrations
WHERE ((tblRegistrations.StatusID)=1)
GROUP BY tblRegistrations.UserID, tblRegistrations.CourseID;
The second query I wrote was to get the "Last Not Completed" registration dates. Again I grouped on the UserID and the CourseID, but this time I took the aggregate MAX of the CourseRegistrationDate to get the last time this course was attempted and not completed (with a status equal to 3)
SELECT tblRegistrations.UserID, tblRegistrations.CourseID, Max(tblRegistrations.CourseRegistrationDate) AS LastAttempt
FROM tblRegistrations
WHERE (((tblRegistrations.StatusID)=3))
GROUP BY tblRegistrations.UserID, tblRegistrations.CourseID;
The third query I wrote was to get the unique UserID/CourseID relationships, and that simply grouped them.
SELECT tblRegistrations.CourseID, tblRegistrations.UserID
FROM tblRegistrations
GROUP BY tblRegistrations.CourseID, tblRegistrations.UserID;
Finally, I wrote my result query which makes sure to pull every UserID/CourseID combination, and then show whether it was completed or not, and the requested date.
SELECT qryUserCourses.UserID, qryUserCourses.CourseID, Nz([FirstCompleted],[LastAttempt]) AS ResultDate, IIf([FirstCompleted],"Completed","Not Completed") AS Result
FROM (qryUserCourses
LEFT JOIN qryFirstCompleted ON (qryUserCourses.CourseID = qryFirstCompleted.CourseID) AND (qryUserCourses.UserID = qryFirstCompleted.UserID))
LEFT JOIN qryLastNotCompleted ON (qryUserCourses.CourseID = qryLastNotCompleted.CourseID) AND (qryUserCourses.UserID = qryLastNotCompleted.UserID);
This produced, for me, a list of UserIDs, CourseIDs, a date, and completion status.
I'd like to consult one thing. I have table in DB. It has 2 columns and looks like this:
Name...bilance
Jane...+3
Jane...-5
Jane...0
Jane...-8
Jane...-2
Paul...-1
Paul...2
Paul....9
Paul...1
...
I have to walk through this table and if I find record with different "name" (than was on previous row) I process all rows with the previous "name". (If I step on the first Paul row I process all Jane rows)
The processing goes like this:
Now I work only with Jane records and walk through them one by one. On each record I stop and compare it with all previous Jane rows one by one.
The task is to sumarize "bilance" column (in the scope of actual person) if they have different signs
Summary:
I loop through this table in 3 levels paralelly (nested loops)
1st level = search for changes of "name" column
2nd level = if change was found, get all rows with previous "name" and walk through them
3rd level = on each row stop and walk through all previous rows with current "name"
Can this be solved only using CURSOR and FETCHING, or is there some smoother solution?
My real table has 30 000 rows and 1500 people and If I do the logic in PHP, it takes long minutes and than timeouts. So I would like to rewrite it to MS SQL 2000 (no other DB is allowed). Are cursors fast solution or is it better to use something else?
Thank you for your opinions.
UPDATE:
There are lots of questions about my "summarization". Problem is a little bit more difficult than I explained. I simplified it just to describe my algorithm.
Each row of my table contains much more columns. The most important is month. That's why there are more rows for each person. Each is for different month.
"Bilances" are "working overtimes" and "arrear hours" of workers. And I need to sumarize + and - bilances to neutralize them using values from previous months. I want to have as many zeroes as possible. All the table must stay as it is, just bilances must be changed to zeroes.
Example:
Row (Jane -5) will be summarized with row (Jane +3). Instead of 3 I will get 0 and instead of -5 I will get -2. Because I used this -5 to reduce +3.
Next row (Jane 0) won't be affected
Next row (Jane -8) can not be used, because all previous bilances are negative
etc.
You can sum all the values per name using a single SQL statement:
select
name,
sum(bilance) as bilance_sum
from
my_table
group by
name
order by
name
On the face of it, it sounds like this should do what you want:
select Name, sum(bilance)
from table
group by Name
order by Name
If not, you might need to elaborate on how the Names are sorted and what you mean by "summarize".
I'm not sure what you mean by this line... "The task is to sumarize "bilance" column (in the scope of actual person) if they have different signs".
But, it may be possible to use a group by query to get a lot of what you need.
select name, case when bilance < 0 then 'negative' when bilance >= 0 then 'positive', count(*)
from table
group by name, bilance
That might not be perfect syntax for the case statement, but it should get you really close.
