Counting The Number Of Groups. Please Help!!!!
Oct 18, 2007
Counting groups
I have the following code that is grouped by name
Mike G ( from 2000 €“ 2003)
Address Raise
Test 1
Test 1
Mike G ( from 2004 €“ 2007)
Address Raise
Test 2 1
Test 2 1
Mark G ( from 2004 €“ 2007)
Address Raise
Test 2 1
Test 2 1
Total 6 (I get this without any problem)
The problem I am having is trying to find out how many groups we have to use the value for some other calculation. So I did this Count(Field .Name) wich will give me 6 instead of 3 . The reason is in my dataset it will be something like that
Name add raise Period
Mike G Test 1 2000-2003
Mike G Test 1 2000-2003
Mike G Test 1 2004-2004
Mike G Test 1 2004-2007
Mike G Test2 1 2004-2007
Mike G Test2 1 2004-2007
If I do CountDistinct(Field .Name) it will give me 2 which is also wrong . So how can I count many groups we have. I spend a lot of time on this please help!
Thanks

Lets suppose I have a db which looks like:District FundVAE AVAW AVAE BDC CDC ANYS BMD CVAW AI would like a query which displays the following dynamically. I don't know each unique member of the Fund field, they could be added by the end user. It might include M,J,S etc. I need the columns dynamically created. I can do it statically if I know the distinct members of fund. I would like to be able to do it dynamically. Any ideas? The static version with multiple queries is at the end.District Total A B CVAE 2 1 1 VAW 2 2 DC 3 2 1 NYS 1 1 MD 1 1
Query Name =GroupByDistSELECT district, COUNT(district) AS dcountFROM dbo.mydbGROUP BY districtQuery Name=DCountASELECT district, COUNT(district) AS dcountFROM dbo.mydbWHERE (fund = N'A')GROUP BY district
Query Name=DCountBSELECT district, COUNT(district) AS dcountFROM dbo.mydbWHERE (fund = N'B')GROUP BY district
Query Name=DCountCSELECT district, COUNT(district) AS dcountFROM dbo.mydbWHERE (fund = N'C')GROUP BY district
SELECT GroupByDist.district, GroupByDist.dcount AS Total, DCountA.dcount AS A, DCountB.dcount AS B, DCountC.dcount AS C From GroupByDist LEFT OUTER JOIN DCountC ON GroupByDist.district = DCountC.district LEFT OUTER JOIN DCountB ON GroupByDist.district = DCountB.district LEFT OUTER JOIN DCountA ON GroupByDist.district = DCountA.district

I have a large table that tells me customers and mailings (~4 million rows). So for each customer, I see what mailing(s) they received. It is at the mailing level so if a customer received 2 mailings, their will be 2 records for that customer number, one for each mailing they received. There are 3 different mailings.I am trying to calculate the count of customers that received all 3, as well as those that received 1&2 only, 1&3 only, and 2&3 only. For example:
CustNo Mailing
Tim 1
Tim 3
Dan 1
Dan 3
Jane 1
Max 1
Max 2
Max 3
Lauren 2
Lauren 3
Results:
All 3 - 1
1&2 only - 0
1&3 only - 2
2&3 only - 1
I have tried doing some funky table joining and EXISTS, but the query runs and runs because of how much data it has to sift through. Here is the code I am using to find Mailing 1&2 only customers, but I am not even sure it is getting me the right numbers. There are 2 different types of customers as well which is why I have custtype in there.
Code:
select a.custtype,count(distinct a.custno)
from myTable a
inner join (select distinct custno from mytable where [mailing]=2) b
on a.custno=b.custno
where a.[mailing]=1
and not exists(select * from myTable c where a.custno=c.custno and c.[mailing]=3)
group by a.custtype

I am having a problem transforming a data set to the structure I need. I have data in the following format.
Id Visit1 Visit2 Visit3 Visit4
1 2Mar2010 27Mar2010 24Apr2010 8Jul2010
2 2Apr2010 3May2010 4Jun2010 11Jul2010
I need to transform it into a table which gives a count of the number of subjects at each visit at the end of each month.
For example, in March there will be 1 subject at visit 2. In April, there will be a total of 2 subjects, 1 at visit 1 and 1 at visit 3. In May there will be 2 subjects, 1 at visit 3 and 1 at visit 2, etc.
Here is the table I was hoping to produce.
Date.....Subjects.......Visit1.....Visit2.....Visit3.....Visit4
March....1.............................1
April......2...................1.........................1
May.......2.............................1..............1
Jun.......2............................................2
Jul.......2...........................................................2

Hi,
I need to count and display the number of records which have GradeTitle="SHO". I'm only starting to use BI development studio and all attempts at using the built in aggregate functions have failed.
Also, the report I wish to create has a fixed number of columns and a fixed number of rows as the info being displayed is really only counting values in the DB. I tried using Table but multiple rows were created.
I'd appreciate if anyone could point me in the right direction, as searching this forum turned out to be pretty fruitless for me.
Thanks in advance,
John

The following SQL works on Access and Oracle to return the number of
Groups(Rows) of the SQL. In MS-SQL this SQL is not valid. What is the
equivalent in MS-SQL?
Select Count(1) FROM (Select ShipRegion, Sum(FREIGHT) as [TotalFreight]
from ORDERS WHERE OrderID < 123456 GROUP BY ShipRegion )
Thanks,

hi,
not sure if the title really expains what I want to achieve...
I have a table which is like :
name groups number
bob 1 160
bob 51 160
bob 101 160
What I need to do is split the 160 into the correct groups..
so the first 50 goes into group 1, then next 50 in group 51, then the next 60 in 101..
so the result would look like :
name groups number
bob 1 50
bob 51 50
bob 101 60
thank you for any advice.

In report builder 2.0, I cannot determine how to display the number of times a field has been filled out when a  one to many relationship is involved. I get an error every time I use two aggregates.
ID, Symptom_ID
1, 111
2, NULL
3, 222
3, 333
3, 444
4, NULL
5, 666
The result should be 3 out of 5 records... Or even better displayed as a percentage of the total 60%

I'm trying to do the following and haven't been able to figure it out.
Say there's a table with these records:
Col1 Col2 Col3
a b c
a b c
a b d
e f g
e f g
I want to generate a number that represents the groups of columns like this:
Col1 Col2 Col3 MyNumber
a b c 1
a b c 1
a b d 2
e f g 3
e f g 3
So that each grouping gets its own identifier. I've tried this:
SELECT Col1, Col2, Col3
row_number() OVER (PARTITION BY Col1, Col2, Col3
ORDER BY Col1, Col2, Col3) AS MyNumber
FROM MyTable
But I get this:
Col1 Col2 Col3 MyNumber
a b c 1
a b c 2
a b d 1
e f g 1
e f g 2

I need to calculate the last two columns (noofgrp and grpsize) No of Groups (count of Clientid) and Group Size (number of clients in each group) according to begtim and endtime. So I tried the following in the first Temp table
GrpSize= count(clientid) over (partition by begtime,endtime) else 0 end
and in the second Temp Table, I have
select
,GrpSize=sum(grpsize)
,NoofGrp=count(distinct grpsize)
From Temp1
The issue is for the date of 5/26, the begtime and endtime are not consistent. in Grp1 (group 1) all clients starts the session at 1030 and ends at 1200 (90 minutes session) except one who starts at 11 and end at 1200 (row 8). For this client since his/her endtime is the same as others, I want that client to be in the first group(Grp1). Reverse is true for the second group (Grp2). All clients begtime is 12:30 and endtime is 1400 but clientid=2 (row 9) who begtime =1230 but endtime = 1300. However, since this client begtime is the same as the rest, I wan that client to be in the second group (grp2) My partition over creates 4 groups rather than two.

I have a new SQL 2005 (SP2) Reporting Services server to which I've just upgraded and deployed some SSRS 2000 reports.
I have a subreport that contains a matrix with two groups. The report data seems to be inexplicably repeating the data for the first row in the group for all rows in the group. Example:
ID1
ID2
DisplayData
1
1
A
1
2
B
1
3
C
2
1
A
2
2
B
2
3
C
Parent group is on ID1, child group is on ID2, report would show:
1
1
A
2
A
3
A
2
1
A
2
A
3
A
Is this a matrix bug in 2005 SP2, or do I need to do something differently? I can no longer pull a comparison version from an SSRS 2000 server to verify, but I believe it was working as expected before...

I am working on writing a query to use with Reporting Services where I am pulling grades from a school grade book trying to see what students qualify for Honor Roll.
I have one Honor Roll done but am still working on the other. The qualifications I am trying to get is that a student has a gpa >3.0 and can have one C grade. I've got the 3.0 and the C's down but how to get the query to pull anyone having at the most one C. It doesn't matter whether it is C+, C, or C- but the student can't have more than a count of one.
Here is what I have
SELECT DISTINCT s.lastname+','+' '+s.firstname AS Student, s.studentnumber,e.grade,t.name AS Term,
gs.score, c.name AS Course, se.teacherdisplay
FROM GradingScore gs
INNER JOIN student s ON s.personid = gs.personid
INNER JOIN v_TermGpa tg ON tg.personid = s.personid
INNER JOIN enrollment e ON e.enrollmentid = s.enrollmentid AND e.calendarid = gs.calendarid
INNER JOIN scheduleStructure ss ON ss.calendarid = gs.calendarid
INNER JOIN Termschedule ts ON ts.structureid = ss.structureid
INNER JOIN Term t ON t.termscheduleid = ts.termscheduleid
INNER JOIN section se ON se.sectionid = gs.sectionid
INNER JOIN course c ON c.courseid = se.courseid
WHERE gs.calendarID = 20 AND t.name ='1st 6wk' AND tg.term1gpa >=3.0 AND s.enddate IS NULL
AND gs.score <='C-'
AND (select gs1.personid, gs1.score
from gradingscore gs1
inner join enrollment e1 on e1.personid = gs1.personid
Inner join schedulestructure ss1 on ss1.calendarid = e1.calendarid
Inner join termschedule ts1 on ts1.structureid = ss1.structureid
Inner join term t1 on t1.termscheduleid = ts1.termscheduleid
where gs1.score IN('C','C+','C-') and (count(score)= 0 or count(score) < 2))
ORDER BY s.[student]
I can get it to work all the way up to where the And (count(score) starts then there is something about the way the count is in there that I haven't figured out yet.
Thanks in Advance for any help or advice

Hi all,
I would like to have my SQL statement result to return an additional "column", automatically adding an "auto-increasing" number with it.
So if I for example select all Dates older than today's date, I would want something like this:
1
10/12/2006
2
10/18/2006
3
10/20/2006
4
10/22/2006
5
10/30/2006
Keep in mind that it's not my intention to fysically insert the "counting" column into the table, but rather do it "virtually".
Is this possible? And if yes, how ? :)
Thanks in advance

Sorry for all the code below. I am realizing that my DB design is bad but I already have 7 pages built around it that work fine...until now, so I would really like to not change the DB if possible. My table has 22 columns: iID which is the identity colum. Then there is iAsmtID which is the assessment ID. Lastly there are 20 colums- q1 through q20, each of which will have a 1, 2, or 3, depending on the radio buttons the user clicked. Nows my problem. I have to find a percent for the assessment. It works like this. 3s are NA so we are not worried about them now. I need to find the number of ones and the number of twos for each assessment ID. Then add those together and divide by the number of ones. How can I find the number of the ones and twos. I have below but its not working. Says there is incorrect syntax at the ',' which is a different color below.

Hi everyone,
another problem:
I'm trying to count the number of rows but it's not working. Here's my code:
SELECT 'TOTAL number of rows', count(*) --This counts 4! The total number of rows in [Activites]
FROM [Activities]
WHERE [Person ID] IN
(
SELECT DISTINCT [Person ID] --This brings back 2 rows (two specific people)
FROM [Activites]
)
As my comments say, I'm wanting to count the two rows but it's counting every row. Obviously I'm doing something wrong but I can't work it out.
Any help?

Hi,
I'm trying to include the COUNT(*) value of a sub-query in the results of a parent query. My SQL code is:
SELECT appt.ref, (Case When noteCount > 0 Then 1 Else 0 End) AS notes FROM touchAppointments appt, (SELECT COUNT(*) as noteCount FROM touchNotes WHERE appointment=touchAppointments.ref) note WHERE appt.practitioner=1
This comes up with an error basically saying that 'touchAppointments' isn't valid in the subquery. How can I get this statement to work and return the number of notes that relate to the relevant appointment?
Cheers.

How can I aggregate a top 5 count across two satellite tables?
e.g. Orders and downloads table each have multiple entries for the same customer ID I would like to count the orders and add them to the downloads count too e.g. 5 orders added to 10 downloads giving 15 as the total for this customer and get a total 'site activity' result which I would like to select the top 5 for.

Hi. I have a small problem that i just can't seem to figure out. I'm trying to generate a report for a case management system. The problem I am having is trying to exclude some of these results. Here is my query:
SELECT COUNT(DefendantCase.ProsAtty) AS CountOfProsAtty
FROM DefendantCase LEFT JOIN DefendantEventPros ON DefendantCase.VBKey=DefendantEventPros.VBKey
WHERE DefendantCase.StatusID=17 AND DefendantCase.ProsAtty=55
AND DefendantEventPros.EventDate BETWEEN DATEADD(DAY,-60,GETDATE()) AND GETDATE() AND DefendantEventPros.EventID=9
This query is trying to find the total amount of cases where the statusid=17, the prosatty=55, the date is between today and 60 days ago, and there is an eventid=9.
now, i'm not getting errors in the query itself; it's just that it's inflating the total number. If a case has more than one eventid=9, it will include that extra in the results. I do not want to include those in the results. Does anyone have any suggestions? Thanks!

hiya all,
I got a table that is represented as a B-Tree, it has a one to
many relation with its self
------------
| UserID |
------------
|FatherID|
------------
UserID = FatherID
it looks like this
o
/// \
ooo ooo
//\ ///\
oo ooo ooo
I want to get all the nodes that has 256 children and grand children and each node is limited to have 6 nodes under it.
any ideas ? the DB isn't filled with data yet so we can add more fields
to the table if it helps.
I could write a trigger that increments a counter in each node but it will be a recursive trigger so it can go from the child to its father and the father to its father upating them and so on.
regards
Ahm
