Returning Average Of Multiple Rows In A Table Join

Jul 23, 2005

Hi,

I'm am looking for a little help. I need to create a SQL view which
joins a few tables, and I need to return an average for a particular
column where a second duplicate ID exists...

Heres an example of how the results could be returned...

ID | Name | Order No. | Value
---+------+-----------+---------
5 | test | 1234 | 3
5 | test2| 1234 | 4
5 | test3| 1234 | 3
5 | void | 1235 | 5
5 | void2| 1235 | 6
5 | void3| 1235 | 5
5 | void4| 1235 | 7

ID is my main join which joins the tables

Name is a unique name

Order No is the same for the different names, I only need to return one
row with this order no, and the first name (the rest are irrelevant)

Value is the field which I wish to return as an average of all 3, 4 or
however many rows is returned and share the same order no. This is
where I get totally lost as I am pretty new to SQL. Can anyone provide
any help on how I would go about limiting this query to the unique
order no's and returning the average of the value field, and I can take
it from there with my own tables.

Thanks for your help

Left Join Not Returning Rows

Nov 3, 2005

SELECT
[tblSections].[pageTitle],
[tblSections].[sectionURL],
[tblSectionContents].[articleID],
[tblSectionContents].[fileID],
[tblSectionContents].[linkID],
[tblCopy].[copyText],
[tblFiles].[fileName],
[tblFiles].[fileCaption],
[tblGroupings].[grouping],
[tblLinks].[linkURL]
FROM [tblSections]
LEFT JOIN [tblSectionContents] ON [tblSectionContents].[sectionID] = [tblSections].[id]
LEFT JOIN [tblCopy] ON [tblSectionContents].[articleID] = [tblCopy].[id]
LEFT JOIN [tblFiles] ON [tblSectionContents].[fileID] = [tblFiles].[id]
LEFT JOIN [tblGroupings] ON [tblFiles].[groupingID] = [tblGroupings].[id]
LEFT JOIN [tblLinks] ON [tblSectionContents].[linkID] = [tblLinks].[id]
WHERE [tblSections].[id]=2
ORDER BY
[tblSectionContents].[articleID],
[tblSectionContents].[fileID],
[tblSectionContents].[linkID]

If I pass it the ID of a section that has files or copy or [stuff in other tables] attached, then I get a result set that makes sense.

But if I pass it a section ID that doesn't reference any other content tables (ie: the section just has a title and a link URL), I don't get anything back.

Shouldn't it should still get me the fields from the row in tblSections that matches the ID I'm passing it?

How can I make it so that it does?

Thanks :)

Left Outer Join Not Returning All/null Rows

Dec 31, 2007

Need some join help...

Table 1 - Modules:
ID | Name
1 | A
2 | B
3 | C

Table 2 - CompanyModules
ModuleID | CompanyID
1 | 1
2 | 1
3 | 1
1 | 2

I'd like to return the following result set:
CompanyModules.CompanyID | Modules.Name | Present
1 | A | True
1 | B | True
1 | C | True
2 | A | True
2 | B | False
2 | C | False

What would be the query for this? Thanks.

Edit: This is the query I have tried:

select CompanyModules.CompanyID, Modules.Name, count(Modules.ID) as Present from

CompanyModules RIGHT outer Join Modules on CompanyModules.ModuleID = Modules.ID

group By CompanyModules.CompanyID, Modules.Name

Order by CompanyID

However, it only returns a partial result set:

CompanyModules.CompanyID | Modules.Name | Present
1 | A | 1
1 | B | 1
1 | C | 1
2 | A | 1

Returning Multiple Rows From 2 Tables

Aug 29, 2005

I have two tables and I want to return data from both. Currently my select statement is returning just 1 child record for each parent record and I want to return all child records that match the parent record.

Here's a sample of my tables/data/etc.

t1
------------
speciesid | species
1 | Mammals
2 | Rodents
3 | Reptiles

t2
---------
animalid | animal
3 | Skink
3 | Iguana
3 | Rattlesnake
2 | Meerkat
1 | Hippo
1 | Elk

What I want to do is pull up a list of all the species and under each list all the animals currently listed under that species.

So the result I want should look like:
Mammals (Hippo, Elk)
Reptiles (Skink, Iguana, Rattlesnake)
Rodents (Meerkat)

so currently I have:
SELECT A.animalid, S.speciesid, A.animal, S.species from t2 as A, t1 as S where S.speciesid=A.animalid order by species

this works great, it's just that it only returns one animal instead of all of the animals. Any help would be appreciated.

LIKE Using Subquery Returning Multiple Rows

Jan 30, 2008

This is probably very elementary to someone more experienced, but I'm having a hard time coming up with a way to do the following:

SELECT * FROM Transactions
WHERE MyField LIKE (SELECT MyValues FROM SearchValues)

But I can't because the subquery will return multiple rows. That's all I'm really trying to do - search all the rows in Transactions.MyField for any of the search values returned from the subquery.

And I can't restructure the SearchValues table to combine them into a single-row comma-delimited field or anything like that.

Any help would be appreciated-

Sql Question - Returning Multiple Rows As One Record

Jul 20, 2005

Hi,In the process of localizing the 'regions' table, we added three newtables. The localized data will be stored in the TokenKeys andTokenValues tables. It would be easier if we did away with theTokeyKeys/TokenValues tables and just added a localeid in the regionstable, but this is the desired schema by the client. Here's theschema:Table: regionsid nameabbreviation1 United StatesUSTable: localesid locale1 en_US2 fr_CATable: TokenKeysid key1 db.regions.name2 db.regions.abbreviationTable: TokenValuesid keyid valuelocaleid1 1 Etas Unis22 2 EU2The old sql was simply this:select name, abbreviation from regionswhich returns:United States, USBut the new sql needs to link in the localized data from the tokeykeysand tokenvalues tables using the localeid... I�m trying to figure outwhat the sql statement would look like to return this:Etats Unis, EU (This is supposed to be the French version)My confusion is we are trying to return multiple column values fromthe same column (TokenValues.value) and make them act as separatecolumns in the same record, like it was with the original.Thanks

Inner Join Returns Multiple Duplicated Rows

Returning A Floating Point Average

Jan 20, 2008

Hi SQL people,
I have rating system on pages in my website, each page being rated one to five by users. At the back end, an ASP.NET page displays the average rating and number of ratings for each page. As the rating is stored as an integer, the SQL statement returns an integer average. I would like to get a floating point average. Currently the statement used to return the average looks like this:

select AVG(Rating) as AverageRating from Ratings where [RatingPage] = @RatingPage

Is there a simple way to modify this to return a floating point average without iterating through the records, or converting the Rating field to a float?

Thanks for helping!

SQL 2012 :: Table (with Zero Rows) Not Returning Any Result

Jun 26, 2014

I am trying to run queries on a table (table has zero rows). Inspite of giving 0 rows returned the query keeps on running and I have to cancel it. I tried inserting a dummy row into the table but even the insert operation is taking too long.Every query which I hit on the table just keeps on running without giving any result.

But this is not the case with other tables in the database.They are all running fine giving proper results. But this one table is behaving funny.

Returning Table Rows From Custom Code?

Sep 28, 2007

I wish to call a custom code function from a table control that would return rows of data to be displayed in the table. Is this possible?

Specifically, I'd like to pass a large text string to the function, have the function break the string into smaller strings, and then have the smaller strings displayed in the table. The number of lines returned may vary, depending on the original string passed in.

Returning Multiple Results From A Cursor Into A Table

Sep 7, 2007

The problem I'm having is that I need a cursor to return multiple results into 1 .NET System.Data.DataTable, and I don't know if it's possible. Actually, the real problem I'm having is that whoever designed this database did a poor job and if it weren't for one small thing I could do this all with aggregates...

But more specifically, this is what I need to accomplish. I have written a cursor that I know works - when I run it in MS SQL Query Analyzer, I get the results I want, but it's returned in multiple tables. I am maintaining a .NET application with some pretty lousy performance and I'm trying to boost it up. I need to take the cursor's results, stuff them into a DataTable, and then return that table to my web application to render.

In my C# code, I am using a SqlDataAdapter to execute my query. This is what I'd like to do...

/*assume query is my working cursor, InvoiceDBConnection is not null, and dt is an empty, non-null DataTable*/

SqlDataAdapter sda = new SqlDataAdapter(query, InvoiceDBConnection);
sda.Fill(dt);

... but this doesn't work, and it makes sense, I guess...since the cursor returns multiple "tables" (not sure if that's actually how the data is returned).

So is there any way to accomplish what I want to do? Or do I have to do it the crappy way it's done now by running my aggregate query and then using a really time-consuming for loop on my results to make the necessary adjustment?

Any help is greatly appreciated

Select DISTINCT On Multiple Columns Is Not Returning Distinct Rows?

Jul 6, 2007

Hi, I have the following script segment which is failing:

CREATE TABLE #LatLong (Latitude DECIMAL, Longitude DECIMAL, PRIMARY KEY (Latitude, Longitude))

INSERT INTO #LatLong SELECT DISTINCT Latitude, Longitude FROM RGCcache

When I run it I get the following error: "Violation of PRIMARY KEY constraint 'PK__#LatLong__________7CE3D9D4'. Cannot insert duplicate key in object 'dbo.#LatLong'."

Im not sure how this is failing as when I try creating another table with 2 decimal columns and repeated values, select distinct only returns distinct pairs of values.

The failure may be related to the fact that RGCcache has about 10 million rows, but I can't see why.

Any ideas?

INNER JOIN Between A CLR-TVF And A Table Returns No Rows

Feb 24, 2007

I have the following query:

select sq.*, p.numero, p.nombre
from paf p right outer join dbo.GetListOfSquaresForShippingLot(@lot) sq on sq.number = p.numero and sq.version = p.numero

The @lot parameter is declared at the top ( declare @lot int; set @lot = 1; ). GetListOfSquaresForShippingLot is a CLR TVF coded in C#. The TVF queries a XML field in the database and returns nodes as rows, and this is completed with information from a table.

If I run a query with the TVF only, it returns data; but if I try to join the TVF with a table, it returns empty, even when I'm expecting matches. I thought the problem was the data from the TVF was been streamed and that's why it could not be joined with the data from the table.

I tried to solve that problem by creating a T-SQL multiline TVF that is supposed to generate a temporary table. This didn't fix the problem.

What can I do? Does anybody know if I can force the TVF to render its data somewhere so the JOIN works? I was thinking a rowset function could help, but I just can't figure out how.

PLEASE HELP!!!!

Let me know if you want the code for the CLR TVF. This is the code for the T-SQL TVF:

CREATE FUNCTION [dbo].[GetTabListOfSquaresForShippingLot]
(
@ShippingLot int
)
RETURNS
@result TABLE
(
Number int, Version int, Position smallint,
SubModel smallint, Quantity smallint,
SquareId nvarchar(5),
ParentSquareId nvarchar(5),
IsSash smallint,
IsGlazingBead smallint,
Width float,
Height float,
GlassNumber smallint,
GlassWidth float,
GlassHeight float
)

INSERT INTO @result
SELECT *

Duplicate Result Rows From 2 Table Join

May 7, 2012

I am using SLQ Server 2008 R2. The database was designed by another company.

I have two tables: Client and Client_Location. In the Client table the pk is Client_ID. There is also a unique key: sys_Client_ID. Both the Client_ID and the sys_Client_ID fields exist as a foreign keys in the Client_Location table. However, the fields are not noted as unique in the Client_Location table. There are two fields in the Client_Location table that determine when the address was effective. They are from_dt and end_dt.

Multiple records have been loaded into the Client_Location table to track old as well as current addresses of clients.

I'm trying to run a report that will pull clients with a plan_id constraint from the Client table and join the Client_Location table to retrieve the current address of these clients.

My SQL is:

select distinct (a.client_id), a.cli_last AS Last_Name,
a.cli_first AS First_Name, a.cli_middle AS Mid_Init,
b.city AS City, b.county AS County, b.state AS State
from ECBH.dbo.tbl_Client a inner join ECBH.dbo.tbl_Client_Location b
on a.client_id = b.client_id
inner join ECBH.dbo.tbl_client_insurance c
on a.client_id = c.client_id
inner join ECBH_TEST.dbo.tbl_GEF_County d
on b.county = d.COUNTY_NAME
where c.plan_id = 4
order by a.cli_last, a.cli_first

Because multiple records exist in the Client_Location table, the result set has duplicates. How can I pull only the results where the from_dt is most recent?

Multiple Join On Same Table

Jan 1, 2014

I am struggling with joining on the same table and cannot seem to get my head around the solution.

I have three tables as follows:

Patients Samples Results
UniqueID UniqueID
Surname LabNumber LabNumber
Forename (etc.) Sampled Code
Result

The code is the name of the test and the result is just that. Not all patients will have the same set of results. What I'd now like to do is pull out a CSV file of all results from 2013 including where the result is null. The format I am looking for is along the following lines:

Sex, Age, AKIN2, AKIN7, RIFLE,

The AKIN2, AKIN7 and RIFLE are the codes in the result table. I have tried OUTER JOINS but it seems to only pull out those records that exist (example below). I need to specify the result codes I am interested in otherwise the output could be enormous but this then does not pull out null values (a NULL value is an important as an actual value).

SELECT
Samples.Patient_ID AS ID,
Samples.LabNo As LabNo,
Patients.Sex As Sex,
DATEDIFF(year, Patients.DoB, Samples.Sampled) AS Age,
Samples.Source as Source,

Table Join Statement Returns Repeat Rows

Jul 22, 2007

Hello All.

I am struggling with the below join block in my stored procedure.
I can't seem to get the duplicate row problem to go away. It seems that SQL is treating each new instance of an email address as reason to create a new row despite the UNIONs.
I understand that if I am using UNION, using DISTINCT is redundant and will not solve the duplicate row problem.

Primary Keys: none of the email address columns are primary keys. Each table has an incrementing ID column that serves
as the primary key.

I am guessing I am encountering this problem because of how
I have structured my Join statements? Is it possible to offer advice without a deeper understanding of my data model or
do you need more information?

Thanks for any tips.

Code:

select emailAddress from Users union
select user_name from PersonalPhotos union
select email_address from EditProfile union
select email_address from SavedSearches union
select distinct email_address from UserPrecedence union
select email_address from LastLogin) drv
Left Join Users tab1 on (drv.emailAddress = tab1.emailAddress)
Inner Join UserPrecedence tab5 on tab5.UserID=tab1.UserID
Left Join PersonalPhotos tab2 on (drv.emailAddress = tab2.user_name)
Left Join LastLogin tab4 on (drv.emailAddress = tab4.email_address)
Left Join EditProfile tab3 on (drv.emailAddress = tab3.email_address)
Left Join SavedSearches tab6 on (drv.emailAddress = tab6.email_address

Hi there. I haven't been able to figure out how to join a table on column on multiple table names. Here's the situation:

I have a table "tblJob" with a key of jobID. Now for every jobID, the program creates a new table that keeps track of the stock before the jobId was processed and after it was processed to give accurate stock levels and show the difference in stock levels. So, a jobID of 355 would be related to the table: "tblPreStock_335" and "tblPostStock_335". These 2 tables have all the materials in stock and the quantity. Therefore they show how much material was used. I need to figure out the difference in the material in the stock before and after the processing.

That means that I have to get a stockID, get the associated pre and post tables, and then display the difference of ALL the materials in the pre and post tables.

Could someone help me get started on the right path? Even a link to similiar problem that I haven't found would be nice.

Thx

Using Outer Join In Multiple Table Query

Dec 16, 2004

What is the best way to use a left join in a SQL statement with multiple tables (more than 2)? I have a query that uses 7 tables, where most of the joins are inner joins, except for one, which needs to be a left join. The current SQL statement looks something like this:

SELECT [table1].[field1], [table2].[field1], [table3].[field1], [table4].[field1], [table5].[field1], [table6].[field1], [table7].[field1]

FROM [table1],[table2],[table3],[table4],[table5],[table6],[table7]
WHERE
[table4].[field2]=[table1.field2]{this is an inner join}
[table4].[field2]=[table2.field2]{this is an inner join}
[table4].[field2]=[table3.field2]{this is an inner join}
[table4].[field2]=[table5.field2]{this is an inner join}
[table5].[field3]=[table6.field2]{this is an inner join}
[table5].[field4]=[table7.field2]{this is needs to be a left join}

As it stands now, the last line in the WHERE clause is an INNER JOIN and limits the number of rows in my result. I need to select rows from [table7].[field2] whether or not a matching record exists in [table5].[field4]. The other INNER JOINS in the SQL statement must have matching records. Please advise.

Transact SQL :: Update Table From Another Table For Multiple Rows

Jun 10, 2015

Matrix table has ID column and data below.

ID        Flag     TestDate         Value Comment
111 2 12/15/2014     7.5    null
222     2    Null 10          received

Matrix_Current table could have 1 or multiple rows as below.

ID       Flag             TestDate          Value Comment
111         2                  01/26/2015        7.9
111         2                  02/23/2015        7.9
111         2                  04/07/2015        6.8
222       1           null      8         test comment 1
222        3           null     9       test comment 2

When I run below update

UPDATE AM
SET  M.Flag = MC.Flag, M.TestDate = MC.TestDate,
M.Value = MC.Value, M.comment = MC.Comment
FROM dbo.Matrix M inner join dbo.Matrix_Current MC on M.ID = MC.ID

Matrix table has value below:

ID        Flag     TestDate         Value Comment
111 2 01/26/2015     7.9
222     1    Null 8        test comment 1

I want to update Matrix table from all row from Matrix_Current, final table would like below:

ID        Flag     TestDate        Value Comment
111         2 04/07/2015     6.8
222     3    Null 9       test comment 2

Report Designer: Need To List Fields From Multiple Result Rows As Comma Seperated List (like A JOIN On Parameters)

Apr 9, 2008

I know I can do a JOIN(parameter, "some seperator") and it will build me a list/string of all the values in the multiselect parameter.

However, I want to do the same thing with all the occurances of a field in my result set (each row being an occurance).

For example say I have a form that is being printed which will pull in all the medications a patient is currently listed as having perscriptions for. I want to return all those values (say 8) and display them on a single line (or wrap onto additional lines as needed).

Something like:
List of current perscriptions: Allegra, Allegra-D, Clariton, Nasalcort, Sudafed, Zantac

How can I accomplish this?

I was playing with the list box, but that only lets me repeat on a new line, I couldn't find any way to get it to repeate side by side (repeat left to right instead of top to bottom). I played with the orientation options, but that really just lets me adjust how multiple columns are displayed as best I can tell.

Could a custom function of some sort be written to take all the values and spit them out one by one into a comma seperated string?

Select Duplicate Rows And Average Them.

Mar 25, 2008

I have a table with four columns: id, value1, value2, and name. I need to select all duplicate rows with the same name in the name field. Once selected I need to average the value1 and value2 rows with each other. Then I would like to delete the duplicate rows and replace with the new averaged values. Should I first move the duplicate rows to a temp table and then average? Any help would be appreciated.

How can I perform this ?

Or could it be better to get a view of the table above which gets display as follow :
