Nested Query With Distinct Function
Jan 12, 2015
I need to know how many widgets are located at each factory.
I have a table called "Widgets". The pertinent column(s) are:
Factory UID
By using only this table I can group the results by the FactoryUID to get the answer. However, this table does not tell me the factory name.
I have a table called "Factories". The pertinent column(s) are:
FactoryUID
FactoryName
I can join these two tables by the FactoryUID. But I don't know how to write this query so that my results will look like the following table:
FactoryName Widgets
Factory1 100
Factory2 200
Factory3 300

I need to run a SELECT DISTINCT query acrossmultiple fields, but I need to add another field that is NON-DISTINCTto my record set.Here is my query:SELECT DISTINCT lastname, firstname, middleinitial, address1,address2, city, state, zip, age, genderFROM gpresultsWHERE age>='18' and serviceline not in ('4TH','4E','4W')and financialclass not in ('Z','X') and age not in('1','2','3','4','5','6','7','8','9','0')and (CAST (ADMITDATE AS DATETIME) >= DATEDIFF(day, 60, GETDATE()))ORDER BY zipThis query runs perfect. No problems whatsoever. However, I need toalso include another field called "admitdate" that should be treatedas NON-DISTINCT. How do I add this in to the query?I've tried this but doesn't work:SELECT admitdateFROM (SELECT DISTINCT lastname, firstname, middleinitial, address1,address2, city, state, zip, age, gender from gpresults)WHERE age>='18' and serviceline not in ('4TH','4E','4W')and financialclass not in ('Z','X') and age not in('1','2','3','4','5','6','7','8','9','0')and (CAST (ADMITDATE AS DATETIME) >= DATEDIFF(day, 60, GETDATE()))ORDER BY zipThis has to be simple but I do not know the syntax to accomplishthis.Thanks

I want to know how to create a recursive loop/function in SQL, I can’t seem to figure out how to do it.
The database table I am working with is simply the following:
SeedID, ThisParentSeedID
1, 0
2, 1
3, 1
4, 2
5, 4
6, 5
7, 6
8, 7
9, 7
10, 7
11, 10
12, 0
13, 0
14, 0
The example table above shows that SeedID 1 = the parent level of the data. SeedID 2 and 3 are children of SeedID 1, 4 is child of 2, 5 is child of 4... 12 13 and 14 are also parent levels (they are not children of anything).
I want to know how to create a SQL script that is “object oriented� in that I will not have to create as many levels of nested scripts as there are nested “children� in the data.
What I am wanting to figure out is, with a single script, “which sub-children are assigned to [@SeedID]�? So if this script was called, and @SeedID = 1, it would return (2,3,4,5,6,7,8,9,10,11). If @SeedID = 12, it would return null. If @SeedID = 7, it would return (8,9,10,11)
I have tried to keep my question and data as simple as possible for the sake of getting some feedback or help. If you want me to clarify or explain better, please ask me to!

Hello Folks,I encountered a problem with SQL server 2000 and UDFs.I have a scalar UDF and a table UDF where I would like the scalar UDFto provide the argument for the table UDF like in:SELECT*FROMtransaction_tWHEREtrxn_gu_id in (select get_trxns_for_quarter(get_current_quarter( GetDate() ) ))'get_current_quarter' returns an integer which is a GUID in a tablecontaining business quarter definitions, like start date, end date.'get_current_quarter' is a scalar UDF.'get_trxns_for_quarter' will then get all transctions that fall intothat quarter and return their GUID's in a table.'get_trxns_for_quarter' is a table UDF.This doesn't seem to work at all. Regardless whether I provide thenamespace (schema) calling the scalar UDF or not. Error message isjust different.Both functions operate correctly invoked un-nested.The whole expression does work fine if I turn 'get_trxns_for_quarter'into a scalar UDF as well, e.g. by returning just one trxn_gu_id withe.g. MAX() in a scalar datatype. But of course that's no good to me.It also works fine if I select the result of 'get_current_quarter'into a variable and pass that variable into 'get_trxns_for_quarter'.But that's no good to me either since then I cannot use the wholething embedded into other SELECT clauses.Both UDF's are non-deterministic but I couldnt see how that would havean impact anyway.Never mind the syntax on that example or anyhting, I tried all theobvious and not so obvious stuff and it really seems to come down tothe fact that one UDF is scalar and the other one is not. However, Idid not come across any type of information saying that this cannot bedone.Have you any ideas?Any help would be greatly appreciated.Carsten

I have a query that returns employee names and reservations they updated for a set date. Here's a simplified version:
Select Employee.Name, Reservation.ResID
From Employee INNER JOIN Reservation
ON Employee.EmpID = Reservation.EmpID
Where Reservation.DateModified BETWEEN '200510010000' AND '200510050000'
The problem is each employee can update the same reservation several times but I only want it to display that record once. The distinct statement doesn't work because I want the EmpID to be listed more than once. Thanks.

Hi,
I have a query with DISTINCT option. If i use DISTINCT option with aggregate function like SUM will it eliminate duplicate values and then sum the values of a column and what is the syntax for it.
EX I have a column for budget
BUDGET
100
350
275
350
100
so if i use DISTINCT SUM(BUDGET) will it eliminate duplicate values and sum the total.

I need to return a single, unique record for each director. In my example here, I'm getting back 5 records for Bossidy because he has 5 records in the Directorships table each with a unique CompID.
SELECT TDirectors.IDDir, TDirectors.DirFName, TDirectors.DirLName, TDirectors.DirLName + ', ' + TDirectors.DirFName AS DirFullName, TDirectors.ExecutiveTitle, TDirectors.DirGender, TDirectors.DirAge, TDirRace.DirRace,
TDirectors.PrincipalCompany AS CompanyName, TDirectorships.CompID
FROM TDirRace RIGHT OUTER JOIN
TDirectors ON TDirRace.IDDir = TDirectors.IDDir RIGHT OUTER JOIN
TDirectorships ON TDirectors.IDDir = TDirectorships.IDDir
WHERE (TDirectors.DirLName='Bossidy')
I thought I could do this but it doesn't work.
SELECT DISTINCT(TDirectors.IDDir)...
Thanks

My requirement is to count the customer order number for premium order type orders which has some order quantity.I am using below MDX
count
(Â
Filter
(([Customer Order].[Dim Customer Orderkey].[Dim Customer Orderkey].members,
[Outbound Order Attributes].[Order Type].&[P]),[Measures].[Ordered, pcs]>0 ) ,
)
The result is accurate but the query execution time is 3-4 minutes for 10 fact records, when i use multiple dimension. it is showing me 0 valus for this measure for all the members for the dimesion attribute which doen't have any customer order. example it shows all the member of date dimension. is there any way to reduce the rows. i think this is the reason to take more execution time.when i use EXCCLUDEEMPTY the result is NULL
count

(([Customer Order].[Dim Customer Orderkey].[Dim Customer Orderkey].members,
[Outbound Order Attributes].[Order Type].&[C]),[Measures].[Shipped, pcs]>0 ) ,

I am having trouble with the following query.
Important Tables:
Product (table of products)
--ProductID
--ProductName
ProductCategories (Associates a Product with one or more categories)
--ProductID
--CategoryID
Category (table of categories that a product may fall under)
--CategoryID
--CategoryName
Information:
Basically I have a product that falls into two categories. Therefore there are two records in the ProcuctCategories Table. I am trying to create a query that will find all products that are in categories 1 & 2.
Attempted Solution:
SELECT * FROM Product
WHERE (ProductID IN (SELECT CategoryID FROM ProductCategories WHERE CategoryID =1))
AND
(ProductID IN (SELECT CategoryID FROM ProductCategories WHERE CategoryID =2))
This returned zero records though it should have returned the product that is in categories 1&2.
I would appreciate any help available.
Thank you,

Hello Everyone,I am trying to create a query for the purpose of a nested repeater relation. The information needs to be pulled from one table. I have shortened the columns to the ones that are required.table - PagesIDPageNameParentPageIDSo, take the following example:ID 14, PageName - Service A, ParentPage ID = 6ID 15, PageName - Service B, ParentPage ID = 6ID 36 PageName - Client 1, ParentPage ID = 14ID 37 PageName - Client 2, ParentPage ID = 14ID 38 PageName - Client 3, ParentPage ID = 15ID 39 PageName - Client 4, ParentPage ID = 15 So, I want to create a query that will get my nested repeater to display as follows:Service A Client 1 Client 2Service B Client 3 Client 4What I have come up with so far is:SELECT * from tbl_Pages WHERE ParentPageID IN (Select ID From tbl_Pages)SELECT p.ParentPageID, p.PageName, p.ID FROM tbl_Pages pThe relation would be based off ParentPageID. I keep getting errors that either there is no unique value or the relation is null. What am I am missing here?

I am trying to write a query that does not use inner joins to see if it returns rows faster than a query using inner joins.
My trouble is that I don't know how to write the syntax for the 3rd table that I am comparing against.
Can I nest Exists in a Where clause?
If so how is the 2nd exists statement added to the query?
see my sample query below
================================================== ===
'With 2 tables
SELECT DISTINCT s1.ID, s1.SITE
FROM SITE_TBL s1
WHERE EXISTS (SELECT *
FROM DEVICE_TBL d1
WHERE s1.ID = d1.SITE_ID AND d1.DELETEFLAG <> 'D')
ORDER BY SITE
'with 3 tables this doesn't work
SELECT DISTINCT s1.ID, s1.SITE
FROM SITE_TBL s1
WHERE EXISTS (SELECT *
FROM DEVICE_TBL d1
WHERE s1.ID = d1.SITE_ID AND d1.DELETEFLAG <> 'D')
AND
(SELECT *
FROM BIG_TBL b1
WHERE d1.fqdn = b1.xyz)
ORDER BY SITE

Hi, I have the following scenario that I am not sure how to best tackle. Any
advice or examples is appreciated.
I am creating a stored proc that requires a code to be passed to it. In
return data gathered from 3 different tables will be returned. The big catch
is that 1 of the tables resided in a differenct database.
So, here is the data layout.
Database 1, Table 1 contains the following fields: Job, CustID, ShipID, and
ShipMethod.
Database 2, Table 1 contains CustID, ShipID, Address, City, State, Zip,
etc...
Database 2, Table 2 contains CustID, CustomerName.
So the first question is how should the stored proc look with an input
parameter of "Job" and output of Job, CustID, ShipMethod, ShipID, Address,
City, State, Zip, and CustomerName?
Secondly, which database should the stored proc reside?
Again, any advise, suggestions, pointers, etc. are appreciated.

Hi All,
Can anybody please tell me if a query such as this (Valid in MS Access)
can work in SQL Server:
SELECT Description, Sum(Total) FROM (
SELECT Description, Total FROM Table_A
UNION ALL
SELECT Description, Total FROM Table_B
UNION ALL
SELECT Description, Total FROM Table_C
)
GROUP BY Description
The group of unions work by themselves, but when I try to nest an outer query to do some a Summation(), I have syntax errors.
Any insight would be greatly appreciated. Thank you.

Folks
I have two queries
Select Account_Id , Branch_Cd from Accounts
SELECT SUM (dbo.HOLDING.Shares_Par_Value_Qty * dbo.ASSET.Current_Prc) AS MarketValue
FROM dbo.HOLDING INNER JOIN
dbo.ASSET ON dbo.HOLDING.Property_Num = dbo.ASSET.Property_Num
Group by dbo.HOLDING.Account_ID
Account_ID is the same in both the queries ie in both the tables
Holding and Account.
I need the output like this
Select Account_Id, Branch_Cd, MarketValue from -------
But MarketValue should be calculated exactly in the above method.
How do I combine these two queries. I need it asap.
Help me out.

Lets go with some psudo code

Why doesn't the following work, is there a work around?

Dear All,
I need to create a query to list all the subfolders within a folder.
I have a database table that lists the usual properties of each of the folder.
I have another database table that has two columns
1. Parent folder
2. Child folder
But this table maintains the parent child relationship only to one level.
For example if i have a folder X that has a subfolder Y and Z.
And Y has subfolders A and B.
and B has subfolder C and D
and C has subfolder E and F
The database table will look like
parentfolder child folder
X Y
X Z
Y A
Y B
B C
B D
C E
C F
I want to write a query which will take a folder name as the input and will provide me a list of all the folders and subfolders under it. The query should be based on the table (parent - child) and there should not be any restriction on the subfolder levels to search and report for.
I have been banging my head to do this but i have failed so far. Any help on this will be highly appreciated.

I'd appreciate some help with the issue below - my SQL is a bit rusty and was never that hot to be frank. I'm using SQL Server 2000 (although have a test box with 2005 Express also). I've trawled MSDN and a few forums but can't find the solution (maybe I don't know what I'mm looking for!), so any help would be marvellous...
I have a table with a field called 'IRV' containing a string of comma-separated values. I want to be able to query a point in that string and count the number of times a given value appears. So...as an example, I want to count how many times '1' appears at position 7 in the IRV. I can create SQL to do this as follows:
SELECT COUNT(X) AS is1
FROM myIRVtable
WHERE (SUBSTRING(IRV, 7, 1) = '1')
So far so good. However, it is also possible that the value at position 7 in this string could be '2' (or '3', or '4', etc) - and rather than re-running the query again and again to get these values, I'd like to do it in one hit.
How can I combine all this together - anyone have any brilliant solutions?

}
}
}
}
}
return Counter;
}
}
}
This is the output from SQL Server when I call the function.

You can see it adding and checking the values and attempting to call itself, but it never seems to get re-called, any ideas?

Hi,
I am trying to limit a result set by ROW_NUMBER. However, I am having problems getting it working.
The following query works fine, and I get a result set with PollID, AddedDate and RowNum columns.
SELECT *, ROW_NUMBER() OVER (ORDER BY Results.AddedDate DESC) AS RowNum FROM
( SELECT DISTINCT p.PollID, p.AddedDate
FROM vw_vs_PollsWithVoteCount p
JOIN vs_PollOptions o ON p.PollID = o.PollID
) AS Results
However, as soon as I add a WHERE condition:
SELECT *, ROW_NUMBER() OVER (ORDER BY Results.AddedDate DESC) AS RowNum FROM
( SELECT DISTINCT p.PollID, p.AddedDate
FROM vw_vs_PollsWithVoteCount p
JOIN vs_PollOptions o ON p.PollID = o.PollID
) AS Results
WHERE RowNum BETWEEN 1 AND 10
The query fails with an ' Invalid column name 'RowNum' ' error.
I have tried using 'Results.RowNum' but I get the same problem.
I don't understand what the issue is. The result set has a column headed 'RowNum' so why can't I apply a WHERE clause to this column? I can apply WHERE to the PollID column, for example, with no problem.
Any help very much appreciated.
Thanks...

I have added some SQL to an Access form which updates the dbo_BM_Map table when the user hits the Apply button. There is a temp table with various fields, two being "Chapter_No" and "Initial_Mapping_Complete" which the update is based on.
I want this update to only apply to chapters that only have one name in the "Initial_Mapping_Complete" column. If a chapter has more than one then the update should ignore it. The attached screengrab shows you. The update should ignore chapter 19 as there are two people (Jim and James) in the Initial_Mapping_Complete field. Here is my code.
pdate dbo_BM_Map inner Join Temp_Progression_Populate
on dbo_BM_Map.Product_ID = Temp_Progression_Populate.Product_ID
Set dbo_BM_Map.Initial_Mapping_Complete = Temp_Progression_Populate.Initial_Mapping_Complete
Where dbo_BM_Map.Chapter_No = Temp_Progression_Populate.Chapter_No
And Temp_Progression_Populate.Initial_Mapping_Complete in
(Select count(Initial_Mapping_Complete), Chapter_No
from Temp_Progression_Populate
Group by Chapter_No
Having Count(Initial_Mapping_Complete) = 1)

Hi,
I have a following query:
select cu.Currencies_ShortName
from dbo.Currencies cu
inner join
(
select p1.Pairs_Shortname as f1, right(p1.Pairs_Shortname,3) as Currency1,
/*v1*/ -- max(SpotBid) as SpotBid, max(SpotAsk) as SpotAsk
/*v2*/ SpotBid, SpotAsk
from dbo.Pairs p1 inner join dbo.PairsQuotes pq1
on p1.Pairs_Id=pq1.Pairs_Id
and pq1.PriceDate=(select max(PriceDate) from dbo.PairsQuotes)
where p1.Pairs_Shortname like 'EUR%'
/*v1*/ -- group by p1.Pairs_Shortname, right(p1.Pairs_Shortname,3)
) as sr
on cu.Currencies_ShortName=sr.Currency1
which would work like /*v2*/, but not like /*v1*/ - there would be a message:
Server: Msg 8624, Level 16, State 3, Line 1
Internal SQL Server error.
Is Group By not manageable in a nested query, or is it some other problem?
thx
Katarina

My multiple level nested corelated query is not fetching correctresult. It work fine on small set of data, but fails on larger set ofdata. Any clue?Explaining data storing and discussing design would be tough for mehere, still to show you how complex I have created my life, here is thequery:select(SELECT Top 1 RowNSBranchID FROM AssoExtBranchToNSBranchMstM AM-- MMMWHERE AM.RowExtSysID IN(SELECT RowID FROM ExternalSystemMstM WHERE ExtSysID =(SELECT ExtSysID FROM ExternalSystemMstM WHERE SF = 'Active' ANDRowID =(SELECT MAX(RowID) FROM ExternalSystemMstM WHERE MCStatus = 2 ANDExtSysCode = UM.SystemCode)))AND RowExtBranchID IN(SELECT RowID FROM ExternalBranchMstMWHERE ExtBranchID =(SELECT ExtBranchID FROM ExternalBranchMstMWHERE ROWID =(SELECT RowID FROM ExternalBranchMstMWHERE ROWID =(SELECT MAX(ROWID) FROM ExternalBranchMstM WHERE MCStatus = 2 ANDExtBranchCode = UM.UpBranchCodeAND RowExtSysID IN(SELECT RowID FROM ExternalSystemMstM WHERE ExtSysID =(SELECT ExtSysID FROM ExternalSystemMstM WHERE SF = 'Active' ANDRowID =(SELECT MAX(RowID) FROM ExternalSystemMstM WHERE MCStatus = 2AND ExtSysCode = UM.SystemCode))))AND (SF = 'Active'))))AND AM.SF = 'Active'order by AssoID desc,TrackID desc) nsbranchid, UM.*fromTmpInProcessData062005MstM UM
