Unrelated Tables
Mar 7, 2006We're getting duplicate records b/c we're joining two tables that really don't have a unique common field. Does anyone know of a way to join two tables that aren't completely related?? I know this is contradictory to the entire concept of a relational db :).

Sep 8, 2006Hi,
I have two tbls (trade & retail) - at the minute I have a query (in just one tbl) which looks like this
SELECT SUM(Total) AS WeekRetailTotal, COUNT(*) AS MonthRetailOrderNo, DATEPART(wk, OrderDate) AS SalesWeek, YEAR(OrderDate) AS SalesYear
FROM dbo.Orders_Retail
WHERE (account = @Account) AND (OrderStatus <> 'Deleted') AND (PayStatus <> 'Pending') AND (OrderStatus <> 'Refunded') AND (DATEDIFF(d, OrderDate,
@StartDate) <= 0) AND (DATEDIFF(d, OrderDate, @EndDate) >= 0)
GROUP BY YEAR(OrderDate), DATEPART(wk, OrderDate)
ORDER BY YEAR(OrderDate), DATEPART(wk, OrderDate)
I then have the same query (bar a couple of differences) for the trade tbl which looks like this:
SELECT SUM(total) AS WeekTradeTotal, COUNT(*) AS MonthTradeOrderNo, DATEPART(wk, order_date) AS SalesWeek, YEAR(order_date) AS SalesYear
FROM dbo.Orders_Trade
WHERE (order_status <> 'Deleted') AND (account = @Account) AND (order_status <> 'Removed') AND (order_status <> 'Refunded') AND
(TradeCustomerID <> 'Cha928') AND (DATEDIFF(d, order_date, @StartDate) <= 0) AND (DATEDIFF(d, order_date, @EndDate) >= 0)
GROUP BY YEAR(order_date), DATEPART(wk, order_date)
ORDER BY YEAR(order_date), DATEPART(wk, order_date)
Now what I want to do is make one query which has the same WHERE expression(s) but for both tbls at once.
Because the two tbls have a couple of different names in their fields (I.e the retail tbl identifier is called CustomerID and the Trade tbl identifier is called TradeCustomerID). I thought the best bet would be to first dump the data into a temp tbl giving new fields names so that they all match, and then run the query.
But I haven't got a clue how to write a temp tbl SP, nor how to clean it up afterwards as we are talking a whole lot of data...
Any help anyone?
Using Not Exists Between Two Unrelated Tables
Apr 23, 2008
Hello,
I'm struggling with a query that needs to use Not Exists between two unrelated tables. I'm not sure of the best way to handle this with SQL Query Analyzer.
I have three tables, employees, courses and training_records. There is no link between employees and courses other than through the training records table. My problem is that I am unsure of how to pull all employees and an associated course id and course title when there is not a training record for that employee/course?
I had a query that would work when I specified the course id, but I wanted to do this for a list of about 25 courses.
SELECT e.empnumber, e.Nickname + ' ' + e.lastname as employeeName
FROM empdata e
WHERE NOT EXISTS (SELECT * FROM #TrainingRecords tr
LEFT JOIN #TrainingCourses tc
ON tc.ClassID = tr.classid
WHERE tc.ClassID = 1377
AND tr.employee = e.empnumber)
I then modified it to get the classid and name
SELECT e.empnumber, e.Nickname + ' ' + e.lastname as employeeName, tc.ClassID, tc.ClassName
FROM empdata e
LEFT JOIN #TrainingCourses tc
ON tc.ClassID = 1377
WHERE NOT EXISTS (SELECT * FROM #TrainingRecords tr
WHERE tr.ClassID = tc.ClassID
AND tr.employee = e.empnumber)
I then got it to work using the full list
SELECT e.empnumber, e.Nickname + ' ' + e.lastname as employeeName, tc.ClassID, tc.ClassName
FROM empdata e
LEFT JOIN #TrainingCourses tc
ON tc.ClassID in (1032, 1054, 1059, 1060, 1062, 1063, 1069, 1072, 1074, 1075, 1122, 1189, 1190, 1191, 1192, 1193, 1210, 1218, 1219, 1220, 1310, 1377, 1411)
WHERE NOT EXISTS (SELECT * FROM #TrainingRecords tr
WHERE tr.ClassID = tc.ClassID
AND tr.employee = e.empnumber)
My results seem to work like I want them to, but I have never joined a table without actually joining on a value from each table. In this case I join to a list of values and that just looks odd to me. Is this good or crappy development? Is there a better way this should be done?
Database Design Question - Isolated, Unrelated Tables
Jun 25, 2007Hi,I have a question regarding best practices in database design. In arelational database, is it wise/necessary to sometimes create tablesthat are not related to other tables through a foreign Keyrelationship or does this always indicate some sort of underlyingdesign flaw. Something that requires a re evaluation of the problemdomain?The reason I ask is because in our application, the user can perform xnumber of high level operations (creating/updating projects, creating/answering surveys etc. etc.). Different users can perform differentoperations and each operation can manipulate one or more table. Thispart of the system is done and working. Now there is a requirement tohave some sort of audit logging inside the database (separate from thetext based log file that the application generates anyway). This"audit logging" table will contain high level events that occur insidethe application (which may or may not relate to a particularoperation). This table is in some sense related to every other tablein the database, as well as data that is not in the database itself(exceptions, external events etc.). For example : it might haveentries that specify that at time x user created project y, at time Auser filled out survey B, at time C LDAP server was down, At time D anunauthorized login attempt occurred etc.As I said, these seems to suggest a stand alone, floating table with afew fields that store entries regarding whats going on the systemwithout any direct relationship to other tables in the database. But Ijust feel uneasy about creating such an isolated table. Another optionis to store the "logging" information in another schema/database, butthat doubles the maintainance work load. Not really looking forward tomaintaining/designing two different schemas.I had a look at the microsoft adventureworks database schema diagramand they seem to have 3 standalong tables - AWBuildVersion, ErrorLogand DatabaseLog (unless i am reading it wrong!)Any advice, Information or resources are much appreciated.

Thank you very much for your kind attention.
I am having some questions on indexed views and aggregate tables.
My question is: To improve the performance of the queries, is it better to use indexted views or aggregates tables for those aggregates which are often queried?
I am looking forward to hearing from you.

JDBC Deadlock On Unrelated Records
Sep 6, 2005Hi all,I'm regularly getting the "deadlocked..you're the victim" message when twothreads work on a table at the same time via JDBC. The two threads don'tupdate the same records. I suspect the cause is related to index or pagelocks, and/or the fact that the UPDATE statements are doing table scansbecause there's no index on the primary key (no, I'm not the DBA!)1. Thread A selects some records to play with:select top 50I.*,M.this,F.thatfrom APInvoice Iinner join M ...inner join F ...where I.CmStatus = 'O'(There is an index on CmStatus + another column called CmTime, so I expectthis index to be used. It's also the only index on the table.)2. Gradually, within the same transaction that did the SELECT, thread Aupdates all 50 selected records:update APInvoiceset CmStatus = 'S',CmTime = getdate()where itemid = (an ID number from the select in step#1).(There is no index on itemid, which is the unique primary key column)(There is an index on CmStatus + CmTime).3. While step#2 is running, thread B starts and does a single update.That's all that thread B does:update APInvoiceset CmStatus = 'C',CmTime = getdate()where itemid = (an ID number that is NOT in the list of records being usedby thread A)I consistently get deadlocks whenever thread A & B run at the same time.To resolve ths problem, I'm looking at the following actions:1. Create a unique primary index on ITEMID.2. Add an "(UPDLOCK)" or "FOR UPDATE" to the SELECT statement.Are these reasonable things to try? Is there something else I should bedoing?

Mar 12, 2015I've built a robust looking Calendar dimension but that's easy because its all so well structured. Every date belongs to a particular week and every week belongs to a particular month and every month belongs to a particular quarter etc. January 1st is always going to be a member of week 1, month 1, quarter 1.But here's the rub, real life isn't as predictable and stable as a calendar.
Lets say you have an table containing personal information. You might have gender and marital status in there and even though they both relate to one person, they're unrelated to each other so how do you put those in a hierarchy? Which one goes first and which second because you can get combinations of either.
Analysis :: Tabular DAX / Calculate SUM Against Unrelated Table?
Nov 4, 2015I tried using the page below but wasn't able to quite properly adapt it to my scenario
[URL]
I have two UNRELATED (can't be related for reasons outside the scope of this, other relationships already exist) tables.
Each table does, however, contain a WorkerID:
WorkerTimesheets:
WorkerID, HoursLogged, Date
3,10,2015-05-05
3,6,2015-05-10
4,8,2015-05-01
Then the unrelated table "ConstructionSites"
SiteID, SiteManagerID, SiteOpen,SiteClosed
A5, 3,2015-01-01,BLANK
What I want to do is be able to show a measure that SUMS the number of hours logged by anyone who is a SiteManager from the ConstructionSites table.
I wanted to do a SUMX of WorkerTimesheets against HoursLogged, but FILTER against WorkerTimesheets[WorkerID] = ConstructionSites[SiteManagerID] so only workers who are also SiteManager would be counted.However, I can't seem to get that to resolve it always throws an error along the lines that it can't determine context.

View 3 Replies View RelatedAggregates On Aggregates
Jun 13, 2000(MSSQLS7) I have a table with fields similar to the
following:
StudentID
CourseID
CourseArea
EarnedHours
DateTaken
I need to create a report that totals all EarnedHours broken
down by category for a student for a date range. However,
courses can be taken multiple times, but should not count
more than once during the date range (the highest EarnedHours
should be used in the report preferably).
Currently, I've approached this with an SP that creates
a #temp table with CourseID, CourseArea, and MAX(EarnedHours)
GROUP BY CourseID for the date range and student specified,
then I'm selecting SUM(EarnedHours) GROUP BY CourseArea from
that.
Somehow, my current solution seems inelegant, but I haven't
been able to figure out a good way around it. It seems a real
waste to create a temp table, especially since this is a
high-use SP and the actual average subset of records involved
is really low (under 50). I'm probably missing something I
should already know... any ideas?
Aggregates In SQL
Dec 4, 2001Hi,
I have a SQL issue which I know can be solved ( reasonably simply ) but I can't seem to figure it out ( sometimes hard to think in sets ). Basically I have a table:
Report_ID Version date_created created_by
----------- ----------- --------------------------- -----------
17 1 2001-02-21 00:00:00.000 1
17 2 2001-02-22 00:00:00.000 4

12 2 1999-12-03 00:00:00.000 9
what I want to do is pick out all the details of the most recent recent version of each report_ID. i.e.
Report_ID Version date_created created_by
----------- ----------- --------------------------- -----------
17 3 2001-02-24 00:00:00.000 7
12 2 1999-12-03 00:00:00.000 9
I can get a query to return distinct report_ID's with most recent versions, but not all the details.
Any help is appreciated.

Get The Max Of The Aggregates
Sep 10, 2007Hello:
I've been researching a likely common problem with reporting services: the inability to get an aggregate of an aggregate. One particular discussion thread comes close to solving my specific problem:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2021871&SiteID=1
Here's my problem. I have a table that groups data per month based on Count(). I'd like to get the max(count()) -- i.e., which month has the highest count?
For example:
JAN 30
FEB 20
MAR 25
I'd like to identify the month that has the max count. In this case, I'd like to capture the aggregate value "30" as being the max value of the three months displayed.
My goal is to embed a horizontal stacked-bar chart into the table (to the left of the count() values). Various types of medical services are being counted per month: Inpatient Stay, Outpatient Service, PCP visit. The key to displaying the horizontal stacked-bar charts is to make sure the maximum value of the chart is the same for all charts -- i.e., I need to know which month has the highest count and then set that value as the max limit on the chart.
Robert Bruckner's technical article on "Get More out of SQL Server Reporting Services Charts" briefly touches on the topic of embedded charts in a table, but doesn't go into the level of detail I'm considering.
I've also come across related information from SSW Rules to Better Reporting Services. Similar to Robert's article, SSW doesn't address scaling an in-line chart based on data that is aggregated, but rather scaling the in-line chart based on the values found in a specified data field.
Ultimately, I'd like to create an in-line bar chart that appropriate shows the month of JAN as having the longest horizontal bar, and FEB/MAR having appropriately scaled smaller bars.
Thanks in advance!

Aggregates Containing Subqueries...
Sep 20, 2007So I already no this can't be done... but I need a suitable alternative (if one exists) so I don't have to competely re-write this already too huge query.
Anyways, in my select I have something like this:
sum( case when code in (1,2,3,4) then 0 else 1 end ) as total
which has now increase from four static values to a more dynamic format, that being a table with 47 values which may shrink or grow over time. Attempting the following fails:
sum( case when code in (select code_id from ExcludedCodes) then 0 else 1 end ) as total
because apparently you can't use selects or aggregates within an aggregate.
So any ideas on how I can get this working... is there no Array or List type variable I could just substitute in? I've already tried using a Table Variable, but that failed as well.
Please keep in mind, this is one line of a very large select containing many other fields and aggregates (on a fair amount of joins) which is used in at least four differerent reporting queries. If there is no quick and easy replacement trick I can do just let me know so I can start re-writing all of them (which is seriously going to make my head hurt).

Feb 20, 2007I have data that looks like this
create table #TestData
(clt_num int,

insert #TestData (clt_num,proc_cde)
select 1000, 'H0017' union all
select 2000, 'T1016' union all

select 400, '99999' union all
select 500, 'H0017;15' union all
select 500, 'H0036;XX'
I want to select records for a given clt_num based on weights (precedence) given to the different proc_cde(s). The rules for selecting the rows are:
If clt_num only has one row select that row
Select row that has the highest proc_cde by precedence for given clt_num
If clt_num has two or more rows but no proc_cde with an assigned precedence select both rows.
Note that there is a twist with the proc_cds in that they can have garbage at the end in the data records and I don't care about the garbage H0036, H1036;XX will have the same weight.
Therefore my expected results are:
clt_numproc_cde
100H0036;TT
200T1016;XX
30099999;HH
300AAAAA
40099999

In attempting to solve this problem I created a temp table called ProcCde_Weights:
create table #ProcCde_Weights
(proc_cde varchar(10),
weight int)
insert #ProcCde_Weights
(proc_cde,weight)
select 'H0039', 10 union all
select 'T1017', 20 union all
select 'T1016', 30 union all
select 'H0036', 40 union all
select 'T2011', 50 union all
select '90806', 60 union all
select '90862', 70 union all
select 'T1002', 80 union all
select 'H2031', 90 union all
select 'H2023', 100
And wrote this query:
select t.clt_num,
t.proc_cde,
case when p.weight is null then 1000
else p.weight
end as weight
from #TestData t left join #ProcCde_Weights p on t.clt_num = t.clt_num
and p.proc_cde = left(t.proc_cde,5)
which gives me this:
clt_numproc_cdeweight

Select 283, 999999 union all
Select 283, 310 union all
Select 500, 1 union all
Select 100, 90
… which I then combine the ins_num into insurance types:
select clt_num,
case
when ins_num = 1 then 'Caid'
when ins_num = 90 then 'Care'
when ins_num in (189,195,310) then 'HMO'
when ins_num between 381 and 389 then 'TPO'
when ins_num = 999999 then 'TPO'
end as InsuranceType
from #TestData
order by clt_num
… and get the following results:
clt_numInsuranceType
16Caid
16Care
16TPO
16TPO
18Caid
18Care
18TPO
24TPO
24Caid

35TPO
35TPO
100Care
283Caid
283Care
283TPO
283HMO
500Caid
But what I really want is only one line per clt_num and where if clients have more than 1 insurance type the insurance type should be replaced with dual:
clt_numInsuranceType
16Dual
18Dual
24Dual
31Dual
35TPO or Dual (?*)
100Care
283Dual
500Caid
?* This is a special case and I do not know if the results should say Dual or not. I think TPO stands for Third Party Only (in which case they wouldn't care how many third parties the client has and the results should be TPO) … but if I am wrong then this should be Dual. I will ask my boss tomorrow to clarify, but it would be nice to have a solution for both ways.
I know I need to do something with count and stuff, but for some reason I have a mental block when it comes to agregate functions.
Thanks in advance for any help finishing up the query.

The value of the text box is correct, but I can't reference that text box in the grouping function. It says the textbox is undefined.
Any suggestions for a workaraound?

I create a group for GradeID and in the gradeid footer I use Avg(Score). Is there a way to tell RS you want the avg only for the group in scope?
Aggregates Displayed In Group Header.
Nov 12, 2007I have a report that consists of three nested group levels. Each level can be expanded/collapsed. I wanted to have at each level the summed values:
e.g.
+ Group Header 1 Sum1 Sum2 etc..
+ Group Header 2 Sum1 Sum2 etc..
+ Group Header 3 Sum1 Sum2 etc..
Rather I have had to output the aggregated values like so ..
+ Group Header 1
+ Group Header 2
+ Group Header 3
Total Group Footer Sum1 Sum2 etc..
Total Group Footer Sum1 Sum2 etc..
Total Group Footer Sum1 Sum2 etc..
Is there a way to display the aggregated values at the header level of the grouping. I thought this could be possible if I could hide the Group Footer and directly reference the footer sum total values in the header. Any help would be greatly appreciated.

User-Defined Aggregates With Parameters
Mar 25, 2008I have to write an aggregate which accumulates values in a relation to a parameter. Therefore I tried to create an aggregate with an additional input parameter.
While creating the aggregate, I get the following error message:
CREATE AGGREGATE failed because type 'MKT' does not conform to UDAGG specification due to method 'Accumulate'.
Does anybody know, how I could solve this?
Public Sub Accumulate(ByVal value As SQLDouble, ByVal param1 as SQLDouble)
Const uGK as double = 0.008
result = result + Math.Exp(-param1/(uGK *value) )
End Sub
Aggregates Problem (Analysis Services)
May 21, 2008Hi,
I would like to change the aggregate "sum" for "avg" for some of the measures of my cube.
I know it's possible with calculated member (i have already done that) but i would like a more efficient method, in fact i would like the results to be stored in my cube... is that possible ?
Thanks for your help

SQL: Using Multiple Aggregates In One SQL Query Statement
Jan 15, 2008How would you get all those aggregates from the second SELECT statement worked into the first SELECT statement? Can this stuff even all be put into one statement?
What I'm trying to end up with is a table listing the Professor, Course, Year, Registration, and then the amount of A's, B's, etc.
What I have is a table listing the Professor, Course, Year, and Registration. I can also get a list with the counts for each grade. But I need to get the two together somehow. Any thoughts?
SELECT (gp.last_name + ', ' + gp.first_name) AS 'Prof',
gs.course,
LEFT(gs.quarter_year,4) AS 'Year',
COUNT(gs.enroll_id) AS 'Reg'
FROM section s INNER JOIN person p
ON p.person_id = s.person_id
INNER JOIN grade_sheets gs ON gs.section_id = s.section_id
WHERE s.quarter_year = 20073
GROUP BY p.last_name, p.first_name, s.course, s.quarter_year
ORDER BY 'Prof'
SELECT
Count_A =(SELECT COUNT(*) FROM grade_sheets gs WHERE gs.final_grade = 'A' AND gs.section_id = @sectionID),
Count_B =(SELECT COUNT(*) FROM grade_sheets gs WHERE gs.final_grade = 'B' AND gs.section_id = @sectionID),
Count_C =(SELECT COUNT(*) FROM grade_sheets gs WHERE gs.final_grade = 'C' AND gs.section_id = @sectionID),
Count_D =(SELECT COUNT(*) FROM grade_sheets gs WHERE gs.final_grade = 'D' AND gs.section_id = @sectionID),
Count_F =(SELECT COUNT(*) FROM grade_sheets gs WHERE gs.final_grade = 'F' AND gs.section_id = @sectionID)
Conditonal SUM Function, Or Similar Conditional Aggregates
Jul 23, 2005Are there any conditional aggregate functions, such as SUM()?An example would probably be the best way to describe what I'mtrying to do...I have the following table, named Orders, with the following records:ItemNo qty_ord paid------ ----------- ------T101B 1 199.00T101B 1 199.00T101B 1 199.00T101B 1 199.00T101B 1 199.00T101B 1 199.00T101B 1 199.00T101B 1 0.00T101B 1 0.00T101B 1 0.00T101B 1 0.00Z200L 1 50.00Z200L 2 100.00I want to produce the following result set:ItemNo qty_gross qty_net------ ---------- -------T101B 11 7Z200L 3 3The "qty_gross" column in the result set is the sum oftotal items ordered within the ItemNo grouping.Easy enough. However, I also want a column "qty_net" thatis the sum of qty_ord but ONLY IF the amount in the"paid" column is > 0.I tried using the HAVING clause, but that produces acatch 22 situation. If I say "HAVING paid > 0" thenthe qty_gross column is wrong because it leaves out rowsthat contain records with paid = 0 values. If I leaveout the HAVING clause, then the "qty_net" is wrong.Any ideas?select ItemNo, Sum(qty_ord) as qty_gross, Sum(qty_ord) as qty_netfrom Ordersgroup by qty_ord, paid, ItemNohaving paid > 0 ?????Thanks,Robbie
View 1 Replies View RelatedScan Order Of User Defined Aggregates
Oct 12, 2006Hi all!
I have created (in CLR) a user defined aggregate. The scan order of this aggregate is important, because it return different results for different orders.
When i use it with a single group (using order by and where) is working fine.
For example
select id, dbo.cmp(myclolumn) as myres from (select top 100 percent * from mytable order by id,clmdate) where id=10 group by id
This works correctly. Now lets expand it by removing where id=10 clause
select id, dbo.cmp(myclolumn) as myres from (select top 100 percent * from mytable order by id,clmdate) group by id
I get slightly different results from what the right result must be.
Any idea?
Why Would Tables Pulled In From ODBC In Access Be Different Than Tables In SQL 2005 Tables?
Jan 24, 2008I'm new to my company, although not new to SQL 2005 and I found something interesting. I don't have an ERD yet, and so I was asking a co-worker what table some data was in, they told me a table that is NOT in SQL Server 2005's list of tables, views or synonyms.
I thought that was strange, and so I searched over and over again and still I couldn't find it. Then I did a select statement the table that Access thinks exists and SQL Server does not show and to my shock, the select statement pulled in data!
So how did this happen? How can I find the object in SSMS folder listing of tables/views or whatever and what am I overlooking?
Thanks,
Keith
Track The Changes To Normalised Tables And Update The Denormalised Tables Depending On The Changes To Normalised Tables
Dec 7, 2006We have 20 -30 normalized tables in our dartabase . Also we have 4tables where we store the calculated data fron those normalised tables.The Reason we have these 4 denormalised tables is when we try to dothe calcultion on the fly, our site becomes very slow. So We haveprecalculated and stored it in 4 tables.The Process we use to do the precalcultion, will get do thecalculation and and store it in a temp table. It will compare the thetemp with denormalised tables and insert new rows , delte the old oneans update if any changes.This process take about 20 mins - 60mins. Ittakes long time because in this process we first do the calculationregardless of changes and then do a compare to see what are changed andremove if any rows are deleted, and insert new rowsand update thechanges.Now we like to capture the rows/columns changed in the normalisedtables and do only those chages to the denormalised table , which weare hoping will reduce the processing time by atleast 50%WE have upgraded to SQL SERVER 2005.So We like to use the newtechnology for this process.I have to design the a model to capture the changes and updated onlythose changes.I have the list of normalised tables and te columns which will affectthe end results.I thought of using Triggers or OUTPUT clause to capture the changes.Please help me with the any ideas how to design the new process
