Query To Retrieve Unique Records

Jun 7, 2008

I am new to SQL, still learning.

If I want to retreive unique records for e.g. VendorName,City and State however no 2 vendors must be of the same city or state.

How can I do this?

I have used Select and distinct but that still brings unique vendornames in the same state and city. I only need one vendor per city and State.

Help!

Query On Unique Records With Multiple Criteria

Oct 19, 2013

I'm fairly new in SQL. Been trying for months to create the right script for this particular case but still cannot give me 100% result as required.

SCENARIO :

I am required to query from 2 tables for those unique record that meets both conditions below:-
1. Status is 1 @ max (trans_id), paychnl = CC
2. Status is 2 @ max (trans_id), paychnl = A or B

FYR, 2 tables and respective columns to query are as below:-
table PTFF --> col ID, TRANS_ID,TRANSDATE,EFFDATE,TRANSCODE
table CHFF --> col STATUS,PAYCHNL

FYI, status refers to the paychnl method status:-
==> 1 means the current paychnl method
==> 2 means the previous paychnl method

paychnl method can be multiple because it will be defined as 2 for all the histories' paychnl chosen earlier, but 1 should only be unique as it is the latest paychnl chosen for each unique ID. however, it may appear more than once when it's taking those in earlier TRANSDATE, so here we would need the max trans_id as it will show the latest updated TRANSDATE.

Apart from that, I need only those most recent paychnl to be A or B and the latest paychnl is CC so, this been indicated by the same max trans_id for the same ID.

Aft trying so many times on this MAX command but failed to get any result, I only managed to come up to this part only. please refer below:-

table PTFF --> col ID, TRANS_ID,TRANSDATE,EFFDATE,TRANSCODE
table CHFF --> col STATUS,PAYCHNL

SELECT DISTINCT PTFF.TRANSCODE,PTFF.ID,PTFF.TRANS_ID,PTFF.TRANSDATE,PTFF.EFFDATE, CHFF.STATUS,CHFF.PAYCHNL

FROM DBO.PTFF PTFF
JOIN DBO.CHFF CHFF
ON CHFF.ID = PTFF.ID
WHERE
PTFF.TRANSDATE BETWEEN 130501 AND 130831
AND PTFF.TRANSCODE='T522'
AND (CHFF.STATUS=1 AND CHFF.PAYCHNL='CC' OR (CHFF.STATUS=2 AND (CHFF.PAYCHNL='A' OR CHFF.PAYCHNL='B')))

However, the script above returns :-

1. All those records with STATUS 1 regardless paychnl is A or B in most recent status 2,
2. Expected results also appear ==> 1 same ID with status 1 while paychnl=CC and status 2 while paychnl=A or B
3. Also duplicates of expected results but for different TRANSDATE and not at MAX TRANS_ID

Samples of the result:-

IDSTATUSTRANS_IDPAYCHNLTRANSDATEEFFDATETRANSCODE

How To Retrieve Mismatched Records With MS Access Query

Jun 24, 2004

Hi, does anyone know how to retrieve mistmatched records across 2 tables.
To clarify, I have table A with 1175 records and Table B with 894 records.
The records from table A match exactly some the records in table B.

I have tried the query with Select where fields_1.a<>fields_2.b AND fields_2.a<>fields_2.b etc
but that doesn't seem to work.

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

Thanx, Robson

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!

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.

Bug? Report Builder Returning Only Unique Records!

Feb 8, 2007

Our users use Report Builder for writing ad-hoc queries. They have run into a problem where Report Builder is returning only distinct records is the entities unique identifier is not added to the report.

Example:

TransID Type TransQuantity

1 CS 4
2 CS 4
3 CP 2
4 CN 3

Adding the above fields to the report builder canvas will return 4 rows. However, if I were to add only Type and TransQuantity to the canvas as such, Report Builder will only return 3 rows:

Type TransQuantity


CS 4
CP 2
CN 3

Is there any way to have Report Builder return the actual number of records? Our users often will export the results from Report Builder into Excel to slice and dice the data, and with the functionality the Report Builder has right now, incorrect values will be certain.

Thanks,
Taurkon

Selecting Records Where Part-field Is Unique

Aug 10, 2015

I have a very large CSV file containing name-and-address information which I am reading in a Visual Basic project using the Microsoft.JetOLEDB.4.0 provider.

The key field on which the CSV file is to be filtered is the PostCode field.  This is a UK-format PostCode "XXnn Nxx" where "XX" is one or more letters denoting a geographical area within the UK and "nn" is one or more characters (starting with at least one numeric digit) which when combined with the area code denotes a specific district within the geographical area.  My aim is to identify all the unique UK postal districts held within my address CSV file.

Because I do not know how to use SQL to filter on the partial contents of a database field I am presently reduced to extracting unique full PostCodes using "SELECT DISTINCT PostCode,City,County FROM [ADDRESSES.csv]" into a DataTable object, then sequentially reading that DataTable using the operation of a dictionary object to identify unique PostCode areas, to finally construct the DataTable I need.

Is it possible in SQL to select records where the value of a varying number of characters before a space character in a given (PostCode) field is unique?

I'm new to MS SQL and VB. I have a table with one field JOB_NAME containing 20 records. Out of that field I want to retrieve 6 of the 20 records into a pulldown menu. They are all unique text names like so:

Anna Smith
John Doe

etc. I did not see IDs listed for any of the names in the table when I looked.

There is no common denominator to the names that can be filtered in the SELECT statement, and the 6 that I want will need to be pulled out individually.

Is there a way to do this with a SELECT statement? I have not found much information about how to extract unique records out of a single field. Here's the statement I'm using which pulls all of them:

strSQL = "SELECT DISTINCT JOB_NAME AS Names FROM [WORKER_NAMES] WHERE JOB_NAME<>' ' ORDER BY JOB_NAME ASC"

This gives me the total list but I only want to bring back 6 of the 20 for the pulldown.

Is there a way to modify this statement to pull only the records that I want?

Thanks for any help you can give.

SQL Server 2014 :: Getting Unique Number For Groups Of Records?

Aug 6, 2014

I'm trying to do the following and haven't been able to figure it out.

Say there's a table with these records:

Col1 Col2 Col3
a b c
a b c
a b d
e f g
e f g

I want to generate a number that represents the groups of columns like this:

Col1 Col2 Col3 MyNumber
a b c 1
a b c 1
a b d 2
e f g 3
e f g 3

So that each grouping gets its own identifier. I've tried this:

SELECT Col1, Col2, Col3
row_number() OVER (PARTITION BY Col1, Col2, Col3
ORDER BY Col1, Col2, Col3) AS MyNumber
FROM MyTable

But I get this:

Col1 Col2 Col3 MyNumber
a b c 1
a b c 2
a b d 1
e f g 1
e f g 2
