Nested And Aggregate Queries
Nov 14, 2013
I have a the following fields in a table TblToDo
[ToDoID] [int] IDENTITY(1,1)
[ToDoReferralID] [int]
[ToDoDate] [datetime]
[ToDoCompleteBy] [datetime]
[ToDoCompleted] [datetime]
and want to produce a query to show the with following
All Grouped by [ToDoReferralID]
Count [ToDoID] AS [ToDoToTal]
Count [ToDoID]WHERE [ToDoCompleted] IS NULL AS [ToDoIncomplete]
Count [ToDoID]WHERE [ToDoCompleted] IS NULL AND [ToDoCompleteBy] <= GETDATE() AS [IncompleteUTarget]
Count [ToDoID]WHERE [ToDoCompleted] IS NULL AND [ToDoCompleteBy] > GETDATE()AS [IncompleteOTarget]
I can manage a single aggregate but where to being trying to incorporate all into one query.

I'm using the data environment of VB 6.0 to create data reports.
In Oracle you can use a nested aggregate function in a select query like MAX(SUM(Field)). Can I do this in SQL? If so, how?
thanx

Hi everyone,
I have a database with the following tables:
- programmer
- software
- studies(name, splace, cost, course)
I would like to find out which school has the max. nr. of students, but my query - SELECT splace FROM studies HAVING count(name) = (SELECT max(count(name)) FROM studies) - doesn't works, becouse MSSQL doesn't supports nested aggregat functions.
What should I do? Please help me, thanks in advance.

I'm trying to sum a column in a report. in Most columns I can just wrap the row level expression with "Sum()" and it works. However, I have run into a few that give the following error. The Value expression for the text box ‘Textbox241’ specifies a scope that is not valid for a nested aggregate.  The scope must be the same name of the scope specified by the outer aggregate or the name of a group or data region that is contained in the scope specified by the outer aggregate.Here is my row level expression that works.
=Code.Divide(sum(Fields!WeeklyUnits.Value),sum(Fields!EstUnits.Value))
*
(Code.Divide(sum(Fields!EstHours.Value),sum(Fields!EstHours.Value,"Job")))
Here is my attempt to Sum the row level for the footer area.
=Sum(Code.Divide(sum(Fields!WeeklyUnits.Value),sum(Fields!EstUnits.Value))
*
(Code.Divide(sum(Fields!EstHours.Value),sum(Fields!EstHours.Value,"Job"))))

I have this table record:
PHP Code:
ID | NUMBER | DSTART | DEND | ADDRESS |
----------------------------------------------------------------
1 | 9524123 | 12 Dec 95 | 24 Dec 95 | London |
2 | 9524123 | 06 Jan 96 | 15 Jan 96 | Paris |
3 | 084521 | 12 Mar 96 | 15 May 96 | New York |
4 | 084521 | 22 Aug 96 | 25 Aug 96 | Sidney |
---------------------------------------------------------------
Now, I need to build a query to show only the latest DTSTART date
for each NUMBER. The result would be something like this:
PHP Code:
ID | NUMBER | DSTART | DEND | ADDRESS |
----------------------------------------------------------------
2 | 9524123 | 06 Jan 96 | 15 Jan 96 | Paris |
4 | 084521 | 22 Aug 96 | 25 Aug 96 | Sidney |
---------------------------------------------------------------
Can you guys help me to build the queries? Thanks in advance.

Hi,
I apologize if this is not the section where this should be posted.
Below is a link to a post I made in the Visual Basic forum. Now that I think about it, it may be more of a SQL question than a VB one.
I'm trying to run a query on the result of a query. Thank in advance for any help.

Hi Guys,
I am having trouble with a particular query that is beyond my scope of understanding.
Basically I need to pull sales records based on the following criteria:
I have CustomerID, InvoiceNumber, ContractEndDate, MobileNumber, etc..
Customers recontract their mobile phone plans through us, and we have a new sales record for each time they recontract.
For example, CustomerNumber 123 has recontracted 3 times..
once on 2006-01-01, then on 2007-02-12, and finally on 2008-02-15..
So they have a 12 month contract each time.. then come in to recontract it.
So.. a customer has a single Customer Detail record, but may have many sales records attached. And a customer may have several sales for the SAME mobile phone number.
Currently to pull ALL sales records for all customers, my query is this:
Code:
SELECT xxx.CustomerID AS xxx_CustomerID,
xxx.Invoice AS xxx_Invoice,
yyy.PhoneType AS yyy_PhoneType,
yyy.PlanType AS yyy_PlanType,
yyy.ContractEnds AS yyy_ContractEnds,
yyy.MOB AS yyy_MobileNumber
FROM dbo.SaleControl xxx INNER JOIN dbo.SaleDetails yyy ON xxx.Invoice = yyy.Invoice
WHERE yyy.ContractEnds IS NOT NULL
AND xxx.CustomerID IS NOT NULL
We want to get a list of customers that we can call to recontract, based on the ContractEnd field.
However, we want UNIQUE mobile phone numbers, with the LATEST ContrtactEnd date.
So, Customer 123 has 6 sales, for 2 unique Mobile numbers, the sql may be like:
Code:
SELECT MAX(yyy.ContractEnds) AS LatestCED, yyy.MOB
FROM dbo.SaleControl xxx INNER JOIN dbo.SaleDetails yyy ON xxx.Invoice = yyy.Invoice
WHERE xxx.CustomerID='123'
GROUP BY yyy.MOB
Now, this works fine, and of course if i remove the WHERE clause, it collects all unique mobiles, with latest ContractEnd date for each, for all customers. (Customer 123 displays 2 mobile numbers, each with the LATEST ContractEnd date)
BUT i need this information ALONG WITH the other fields (xxx.CustomerID, xxx.Invoice, yyy.PhoneType, yyy.PlanType) and i have tried a few ways of doing it, but can't get my head around it..
Keep getting errors about Aggregate functions and Group By clause, and i understand why i am getting them, just cant think of any alternative query.
Can anyone please help me!
Thanks guys,
Mick

Though I am a novice to MS SQL server (2000 I believe), I can do almost!everything I need. Maybe not efficiently, but usefully. However, I havea problem -- a complex query problem...I can create a parameter query in a stored procedure, but how do I usethe result set of a parameter query in a select query (in the same oranother sp)? In short, if a select query contains a result table that isgenerated as a parameter query, how do I pass the parameter through theselect query to the nested parameter query?For example, if I have a sp parameter query called [e_typerows], I couldwrite the following select query which uses the (single) result set from[e_typerows] plus other tables or views:SELECT TOP 100 PERCENT bi_occ_01_e.row, bi_occ_01_e.pos,bi_dictionary_e.typestring, bi_occ_01_e.shadowFROM bi_dictionary_e INNER JOIN(bi_occ_01_e INNER JOIN[e_typerows] ON bi_occ_01_e.row = [e_typerows].row) ONbi_dictionary_e.typeid = bi_occ_01_e.typeidORDER BY bi_occ_01_e.row, bi_occ_01_e.posEven though [e_typerows] is a (storted procedure) parameter query thiswill work IF my parameter in [e_typerows] has a default, say "yyyy". Inthe default case no parameter needs passing. But what if it doesn't havea default value or if I need to pass a parameter to it?Is there any way to replace[e_typerows]in the above query with somethinglike [e_typerows @myparameter='xxxx']? (Maybe I should try that! I'veseen nothing about it though.)My parameter query, [e_typerows], looks like this in fact:@typestringparameter varchar(100) = "yyyy"SELECT dbo.bi_dictionary_e.typestring, dbo.bi_occ_01_e.rowFROM dbo.bi_occ_01_e INNER JOINdbo.bi_dictionary_e ONdbo.bi_occ_01_e.typeid = dbo.bi_dictionary_e.typeidGROUP BY dbo.bi_dictionary_e.typestring,dbo.bi_occ_01_e.rowHAVING (dbo.bi_dictionary_e.typestring = @typestringparameter)Any suggestions would be greatly appreciated! (For the moment, I firstgenerate the parameter query result set, then I loop through each row ofthat result set and do a select query with that row as a parameter --very complicated!, though it does work.)

I am using Server 2012 and very new to SQL. I have a request from a physician for a list of his patients that meet a criteria. This is stored in a temp table names #cohort.
Using this cohort he wants each row to be one patient with a list of labs, vitals, etc. Three items are the most recent lab value and date. I could query each lab individually and place it into a temp table and then join all temp tables at the end, but I am trying to move past that and have all labs in one temp table. All temp tables are joined with PatientSID.
I tried to do something for just 2 labs, but it is not working. There could be nulls values when joined with the #cohort table.
Individually the SELECT statements pull in the most recent lab value and date, but I cannot get them into a temp table with one row of PatientSID and then the lab value and date if they exist.
IF OBJECT_ID ('TEMPDB..#lab') IS NOT NULL DROP TABLE #lab
SELECT
cohort.PatientSID
,SubQuery1.LabChemResultNumericValueAS 'A1c%'
,SubQuery1.LabChemCompleteDateTimeAS 'A1c% Date'
,SubQuery2.LabChemResultNumericValueAS 'LDL'

Hi,I'm adapting access queries to sql server and I have difficulties withthe following pattern :query1 : SELECT * FROM Query2 WHERE A=@param1query 2: SELECT * FROM Table2 WHERE B=@param2The queries are nested, and they both use parameters.In MS Acccess the management of nested queries with parameters is soeasy (implicit declaration of parameters, transmission of parametersfrom main query to nested query)that I don't know what the syntax should be for stored procedures.The corresponding stored procedure would be something likeCREATE TABLE #TempTable (...table definition...)INSERT INTO #TempTable ExecProc spQuery2 @Param2SELECT * FROM #TempTable WHERE A=@Param1And spQuery2 would be : SELECT * FROM Table2 WHERE B=@ParamI was wondering if this syntax would work and if I can skip theexplicit declaration of #TempTable definition.Thanks for your suggestions.

I have 2 Dimensions in SSAS (see below end), I want to create a calculated member, named
This_Year_Billable_Objective_Count, with its formula = BillableLastYear*(100+ BillableObjective)/100.
The first factor, Â BillableLastYear is a number, aggregated (sum) from child units.
The second factor, Â BillableObjective is a percent number (for example 28 means 28%), it's not aggregate. It's an dependent value for each unit.
How can I calculate This_Year_Billable_Objective_Count for each unit?

HelloWhen I use a PreparedStatement (in jdbc) with the following query:SELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = ?ORDER BY group_nameIt takes a significantly longer time to run (the time it takes forexecuteQuery() to return ) than if I useSELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = 'M'ORDER BY group_nameAfter tracing the problem down, it appears that this is not preciselya java issue, but rather has to do with the underlying cost of runningparameterized queries.When I open up MS Enterprise Manager and type the same query in - italso takes far longer for the parameterized query to run when I usethe version of the query with bind (?) parameters.This only happens when the table in question is large - I am seeingthis behaviour for a table with > 1,000,000 records. It doesn't makesense to me why a parameterized query would run SLOWER than acompletely ad-hoc query when it is supposed to be more efficient.Furthermore, if one were to say that the reason for this behaviour isthat the query is first getting compliled and then the parameters aregetting sent over - thus resulting in a longer percieved executiontime - I would respond that if this were the case then A) it shouldn'tbe any different if it were run against a large or small table B) thisperformance hit should only be experienced the first time that thequery is run C) the performance hit should only be 2x the time for thenon-parameterized query takes to run - the difference in response timeis more like 4-10 times the time it takes for the non parameterizedversion to run!!!Is this a sql-server specific problem or something that would pertainto other databases as well? I there something about the coorect use ofbind parameters that I overall don't understand?If I can provide some hints in Java then this would be great..otherwise, do I need to turn/off certain settings on the databaseitself?If nothing else works, I will have to either find or write a wrapperaround the Statement object that acts like a prepared statement but inreality sends regular Statement objects to the JDBC driver. I wouldthen put some inteligence in the database layer for deciding whetherto use this special -hack- object or a regular prepared statementdepending on the expected overhead. (Obviously this logic would onlybe written in once place.. etc.. IoC.. ) HOWEVER, I would desperatelywant to avoid doing this.Please help :)

I have a table that has 4 colums (id,projectno,date,price)
i want to make a select that returns the sum per project no
i used this query
select projectno,sum(pice) as sum
from supplier
group by projectno
but i want to include additional columns like id and date for the result
but its giving this message:
Column 'supplier.id' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
is there a better way to do so without joining the main table with the upper select query?

I need to get the sum of a field that already has an aggregate function (MAX) performed on it. I am using the following query
Code Snippet
SELECT "tI"."ItemID", MAX("vSS"."ShortDesc") "Short Description",
MAX("tPCT"."FreezeQty") "Freeze Qty", SUM("vSS"."QtyOnHand") "Current Qty",
"tPCT"."BatchKey"
FROM ("vSS" "vSS"
INNER JOIN "tI" "tI"
ON "vSS"."ItemKey"="tI"."ItemKey")
LEFT OUTER JOIN "tPCT" "tPCT"
ON "vSS"."ItemKey"="tPCT"."ItemKey"
WHERE "vSS"."ItemID" = '3002954'
GROUP BY "tI"."ItemID", "tPCT"."BatchKey"
It yields the following results
ItemID
Short Description
Freeze Qty
Current Qty
BatchKey
3002954
SET, WRENCH HEX METRIC
-33
129
42221
3002954
SET, WRENCH HEX METRIC
51
129
42244
3002954
SET, WRENCH HEX METRIC
-31
129
42250
I need to SUM the maximum freeze quantity values per item ID. Therefore for this record, I need the following results:
3002954 SET, WRENCH HEX METRIC -13 129
Can this be done via a subquery? Any assistnance would be greatly appreciated?
Thanks,

Hi,
I have we have a client who gives their invoices in a flat file format, we import it into a SQL Server table.
Nothing is normalized – everything is repeated in every record. The fields are:
customerNumberInvoice_numberPO_numberQtyDescriptionLine_numberLine_totalFreightTaxInvoice_date
So an if an order has 10 line items, the header information (invoice number, PO number, ivoice date) are repeated on each of the lines
I am writing a query to show the following
Order number, Invoice total, Date
select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice_date from invoices group by invoice_no, Invoice, customerNumber
This works great - for each invoice I get the invoice number, InvoiceTotal, and Date
Then I was asked to add the PO Number – this is where I can’t get it right.
When I added “PO_number� to the query, I got two lines for each invoice
select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice, PO_number from invoices group by invoice_no, Invoice, Sold_To_Cust_No, PO_number
Please help - I need to end up with: invoice_no, invoiceTotal, customerNumber, Invoice_date and PO_number (sequence does not matter)
Thanks

I have a table that is used for employee evaluations. There are six questions that are scored either 1, 2, 3, 4, or 5. I want to tally the responses on a page, but I wonder if I can do it without 35 separate calls to the database (I also want to get the average response for each question). I know I can do "SELECT COUNT(intWorkQuality) AS Qual1 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '1' " and then "SELECT COUNT(intWorkQuality) AS Qual2 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '2' " and so on. But can I somehow do the aggregating at the page level, and just refer back to a datasource that uses a generic statement like "SELECT intWorkQuality, intDepend, intAnalyze, intWrite, intOral, intCompatibility FROM dbo.Summer_Project_Req"? If I can, I am not sure what type of control would be best to use or what syntax to use to write the code-behind. I would like the results to be displayed in a grid format. Thanks in advance for your help.

What I'm trying to solve:
I have an application that generates SQL queries, and sometimes uses
DISTINCT where the result set has no dupe rows. In terms of database
resources, I'm trying to figure out if it's worth it to change to app to be
smart enough to not use DISTINCT where it won't serve any purpose, or
whether to let it do the DISTINCT and save added complexity to the query
building application. I.e. what is the cost of DISTINCT where there are no
dupe rows?
What I want to know:
Can someone explain how the stream aggregate operator actually goes about
doing its work?
Does this always create a temp table for sorting and discarding duplicates
(for DISTICNT)? If the answer is "no or sometimes", how does it do so in
the case where a temp table is not involved? I noticed the the estimated
I/O for this operator was zero for some queries I wrote agains pubs. Does
this mean that the optimizer believes the temp table needed will fit
in-memory and creates it in-memory? Or does the estimated I/O figure not
included disk writes for work tables?
tia for any info

Hello,
I was told that on Oracle there's something called an Aggregate Navigator which should be capable of changing the table you're addressing in a query to another table (with aggregate data) and in this way optimize performance in a data warehousing environment.
Is there anything similar in MS SQL Server?

Hi all,
I have a table with the following fields:
carrier,calc_date,ind_id,rcf
I need to run a query to get the following result(by carrier and for each calc_date, calculate the percentage of all individuals who have rcf greater than 0.73):
carrier,calc_date,count of ind with rcf > 0.73, count of all individual, percentage of individuals with rcf's greater than 0.73.
does anyone have an idea of how to achieve that result?

Hi, I am wanting to query the identifier field via the MAX function.
eg.
need to retrieve the BookID of the greatest Book Price
Code:
SELECT BookID,MAX(BookPrice)
FROM Book
this errors, with:
Column 'BookID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
I realise there are other ways such as referencing back on the same table eg.
Code:
SELECT BookID FROM Book WHERE BookPrice = (SELECT MAX(BookPrice) FROM Book)
but was hoping would be a more direct way, is there a specific direct use of MAX for this purpose or another SQL command?

Here's what I have:
1 table that looks like this...
Code:
rep_id answer
1 2
1 1
2 1
3 0
3 1
3 1
4 2
What I want is a recordset returned as ... (columns that tally the 1s and 2s respectively with the rep's id#)
Code:
rep_id total1 total2
1 1 1
2 1 0
3 2 0
4 0 1
What I can do so far is get individual recordsets returned for either total1 or total2 but not together.
Here's what I'm using for these...
Code:
SELECT rep_id, COUNT(answer) as total1
FROM myTable
WHERE answer = '1'
GROUP BY rep_id
and
Code:
SELECT rep_id, COUNT(answer) as total2
FROM myTable
WHERE answer = '2'
GROUP BY rep_id
So how do I form a SQL statement that will combine the 2 columns I have created into 1 joined by the rep_id?
To make it a little stickier there may be some nulls in the existing answers but hopefully that is not going to bung me up.
Any help will be thankfully received!!!

Hi,
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.
Any help or pointers would be a great help!
Thanks.
