Help With A Join That Needs To Return Unique Records

Apr 28, 2008

Hi All,

I need a bit of help with a join. I have 2 tables :

TradeSummary
has fields : SymbolID, CurrentPrice, TotalValue

Trades
has fields : SymbolID, TradeID, ExecutionTime, TradeValue

TradeSummary has one entry for each SymbolID, while Trades contains one or more entries per SymbolID


and what I want to retreive is :


For every item in TradeSummary get CurrentPrice, TotalValue from TradeSummary
and also get TradeValue from Trades for the record for max(ExecutionTime)
tables are joined on TradeSummary.SymbolID = Trades.SymbolID

Every attempt of mine so far returns multiple rows for each SymbolID - I want only one row per SymbolID

thanks in advance

Return Unique Count (Two Values)

Sep 6, 2013

I need a query to return two values. One will be the total units and the other will be total unique units. See exmaple data below. It does not have to be one query. This will be in SP, so I can keep it seperate if I have to.

ID | ID_UNIT
1 | 01
1 | 01
1 | 02
1 | 03
1 | 03
1 | 04
1 | 04

I need two results.

Total Units = 7 - easy to do by using count()
Total unique units = 4 - I cannot use group by as it would return multiple results for each unit, which is not what we want.

How To Return Primary Unique Index Key On Insert

May 27, 2002

Hi,

I am making a program in Visual Basic .NET with SQL Server 2000.

I have a table "MyTable" with a primary key named "Id". The primary key is 'Create Unique' checked and 'Index' selected. When I insert all the fields required, except "Id" of course, I need the new record's "Id" in my VisualBasic program, but I don't know how...

I must do one of them, but don't know how either of them:

-Create a trigger on insertion that will send to the user that sended the insert command the "Id" of the record just created.

or

-get the command in Visual Basic that will send the Insert command with a return field ("Id")

Thanks in advance,
Sebastien Anselmo

Selecting Unique Rows In A Join

Mar 20, 2008

I got the following query:SELECT TOP (8) ext.extID, ext.Quote, ext.sourceTitle, ext.extRating, gf_game.gameID, gf_game.catID, gf_game.URL, gf_game.TitleFROM         gf_game_ext AS ext INNER JOIN                      gf_game ON gf_game.gameID = ext.gameIDWHERE     (ext.Approved = 1)ORDER BY ext.extID DESC which is e.g. producing this output: 6000 -some text- Title 90 1960 2 tom-cl tom cl5999 -some text- title 90 1960 2 tom-clcl asdf5998 -some text- title 90 1959 2 tom-cl-cl asdfWhat I'd like to do now is to filter out the duplicate GameIDs (= 1960) so that just one unique row with the gameid 1960 is remaining. If I put in a SELECT DINSTINCT TOP(8) it just counts for the table ext, but I need it to count for gf_game.gameID - is that possible?Thanks a lot!

Join To Show One Row Per Unique Record

Apr 23, 2015

I am new to SQL but trying to do join a few tables to get result showing showing one row per unique record.

Tables include:-

1. REQ
2. RFQ
3. PO
4. DOCUMENT (contains LAST_DOCUMENT_STATUS, DOCUMENT_ID, DOCUMENT_NUMBER, for example, REQ_CANCELLED, REQ_ID, REQ_NO)
5. DOCUMENT_STATUS (contains status of document, REQ_CREATE)
6. DOCUMENT_TRAIL (contains link between documents, PARENT_DOCUMENT, CURRENT_DOCUMENT, for example, REQ_ID (PARENT_DOCUMENT), RFQ_ID (CURRENT_DOCUMENT)
7. PO_REVISION (contains PO REVISION, when link with DOCUMENT, PO_REV_NO)

Currently when i tried to join all the TABLES, i get multiple lines against REQ_NO.

I realised the multiple lines generated due to the following:-

One to many relationships:
A. RFQ - 1 or more PO
B. PO - 1 or more PO_REVISON

I was thinking how to MAX the records in PO to show only the last PO_REVISION. It seems that DOCUMENT_TRAIL will contain 1 base document PO and 1 or more PO_REVISION.

UNIQUE Records

May 12, 2008

I have the following sql:

SELECT COUNT(patient.patientID) AS total_patients
FROM patient
LEFT JOIN patient_record ON patient_record.patientID = patient.patientID
WHERE sub_categoryID = 4 OR patient_record.allocated = 4

from the database this gives me a COUNT of 22, it should only be 10. I am doing a join and it gives the total records in the two tables where I only want the total in the left table(patient).
How can I GROUP BY patient.patientID in a COUNT query

Help Please Retrieving Unique Records.

Apr 15, 2008

I'm trying to read from a table and return only the unique records from a table.
The table has 3 columns,
ID - Autoinc
Amount - decimal 6,2
Name - varchar(10)

If there are records like

ID Amount Name
1 0.03 Name1
2 0.07 Name9
3 0.05 Name3
4 0.03 Name8
5 0.07 Name4
6 0.06 Name7


I am wanting to retreive only records 3 & 6 (values 0.05
0.06) as they are the only ones where amount is unique i.e. only 1 entry in the table.

I put the following sql statement together which achieves this but it it only returns the amount value
select Count(amount),amount from bids group by amount having count(amount)<2 order by amount

So I then expanded it to read
select Count(amount),amount,name from bids group by amount,name having count(amount)<2 order by amount
not sure where i'm going wrong but the results returned were
0.03
0.03
0.05
0.06
0.07
0.07

Appreciate any help here.

Inserting Unique Records

Apr 24, 2007

Hello,

I have a table with sixty columns in it, five of which define uniqueness for the records. Currently there are 190,775 records in the table. One of the records is a duplicate. I need to insert only the unique records from this table (all columns) into another table. I cannot use a unique nonclistered index with IGNORE_DUP_KEY in the destination table because of a problem I am having with the 'duplicate key was ignored' message. The destination table has a primary key with a clustered index on the same five columns.

How can I put together a SELECT statement that will give me all of the columns in the source table based on uniqueness of the five key columns?

Does my request make sense? Please let me know if you have questions.

Thank you for your help!

I want to select unique country - date pairs. It is not even necessary to have the count of each one, just the list of unique country/dates.

My query here uses 'group by' to accomplish this task, but there may be a way to do this with a self join. I believe using a self join would make the query faster.

1) Is this possible to do with a self join?

Append Only Unique Records In SQL Table

Nov 23, 2007

I have a stored procedure that appends data from a temp table to a destination table.  The procedure is called from an aspx web page. The destination table has an index on certain fields so as to not allow duplicates.
The issue I'm having is if the imported data contains some records that are unique and some that would be duplicate, the procedure stops and no records are appended. How can I have this procedure complete it's run, passing over the duplicates and appending the unique records? Since the data is in a temp table (which gets deleted after each append) should I run some sort of 'find duplicates' query, and delete the duplicates from the temp table first, then append to the destination table?
Thanks in advance.SMc

Pulling Unique Records With Max Dates

Mar 5, 2006

I am trying to pull only those records with a maximum upload date for a file upload log.

This table keeps a list of files uploaded by supplierID and will have multiple records from the same supplier but with all different upload dates. Overall there are over 1,000 records for 48 uniqur suppliers.

The field names are:
SupplierID, UploadDate, FeedFileName, RecordCount, FeedFileDate, RecordCount, and FeedLoaded.

So for each distinct SupplierID I'd like to grab the line item based on the max feedfiledate for each one - in other words I am trying to get the latest uploaded file information, how many records were in the file, and when it was uploaded... I've tried multiple group by and max clauses but there is something I am missing...

Thanks Much in advance

Design For Reporting Unique Records

Apr 12, 2007

Hello,

I'm hoping someone can point me in the right path with a design issue I'm running into. I'm somewhat new with database design and SQL server, so bear with me.

I'm creating a sort of project management system, and I've got a main PROJECT table, and then a STUDENT_PROJECT_PARTICIPANT table, with foreign keys to STUDENT and PROJECT tables. Each has an 'institute' field. What I want to do is to be able to report on the number of students involved in each project, the number of unique students involved in project with a particular institute, and then the number of unique students involved in all projects. I'd also like to be able to report the number of unique students involved in a custom-picked list of projects (this seems the least feasible). The trick is that I need to report this statics within a specific date range. My original idea was to just save statistics of the numbers of students involved in a project every time it is saved, but from there I'm not sure how I can find out the unique count for all projects, since I don't have the date that each student was saved. That's my basic problem. Let me know if you need any clarification.

If anyone has done something similar or has any advice for me on this, please let me know!

Thanks!
Daryl

How To Combine 2 Records Into 1 Unique Record

Jul 11, 2006

Hi all,We have an app that uses SQL 2000. I am trying to track when a code field(selcode) is changed on an order which then causes a status field (status)to change. I tried a trigger but the app may use 2 different updatestatements to change these fields depending on what the user does. When thetrigger fires (on update to selcode), the status field has already beenchanged. So my trigger to record the changes from inserted and deleted donot get the true 'before' value of the status field.The app does use a log table that tracks these changes. The problem I amhaving is that 2 records are created, one for the change to selcode andanother for the change to status.I am looking for help with a script to combine the existence of these 2 logrecords into 1 unique record or occurance that I can track.example:ordlog: table that logs order changesordernr: order numbervarname: name of field being changedold_value: contents of field before changenew_value: contents of field after changesyscreated: date/time of log entrySELECT ordernr, varname, old_value, new_value, syscreatedFROM ordlogwhere varname = 'selcode' and ordernr = '10580'SELECT ordernr, varname, old_value, new_value, syscreatedFROM ordlogwhere varname = 'status' and ordernr = '10580' and old_value = 'A' andnew_value = 'O'So I need a way to combine these 2 log entries into a unique occurance. Theordernr and syscreated could be used to link records. syscreated alwaysappears to be the same for the 2 log entries down to the second. Selcodecan change from NULL to a number of different values or back to NULL.Statusis either 'A' for approved or 'O' for open. An order can have many logentries during its life. The selcode may be changed several times for thesame order.Ideally, I would like a result that links 2 log entries and shows the statuschanged from 'A' to 'O' when selcode changed.Thanks for your time.
