Difficult Select Distinct Query

Jul 20, 2005

Hi,

I have a table as following

aa Text1 aa, Join Bytes!, 15267
aa Text1 aa, Join Bytes!, 16598
aa Text1 aa, Join Bytes!, 17568
aa Text2 aa, Join Bytes!, 25698
aa Text3 aa, Join Bytes!, 12258

I have to write a query as follows ...

SELECT DISTINCT TOP 500 fldText, fldContact, fldItemid
FROM table
WHERE fldCat = 10 AND CONTAINS (fldText, 'Text1')

In the example you can see the table has rows in which text and contact or
double but with different itemid's. Now my employer wants me to show only 1
row when text and contact or the same. He doesn't mind which itemid I show
.... but I have to show one.

I've an idea of how to do this using a cursor and a temporary table but I
guess that will be fatal for the performance because then I have to loop
through all selected rows, check each row with all other rows and store the
primary key in the temporary table if dedected it isn't double. Afterwards
I can execute ... SELECT ... FROM TABLE where primary key in (select
temp_primarykey from #temptable).

I hoped I could do everything in 1 "easy" SELECT but I should not know how?
Any ideas are much appreciated.

Thanks a lot.
Perre Van Wilrijk.

DISTINCT SELECT Query With More Than One Field

Feb 6, 2008

Hello, I want to do a DISTINCT  SELECT query with more than one field, for example a ID field with a Type field, as if both fields make the primary key, like (ID 1 ,Type 1) ,( ID 1, Type 2) and (ID 2, Type 1) is ok but not (ID 1, Type1) and (ID 1,Type 1) if its not possible to do a distinct with more than one then what other techniques are possible to get the duplicate data out.   the reason why I want to use distinct is that I can use that query to export that data to where both of these fields make the primary key.
Thanks in advance

Query Help - Select Distinct Possibly?

Oct 26, 2006

I need to return the current case cost for every UPC in my table. In my current query I return case costs that have an effective date of today or earlier. The problem is that in my results, one UPC may have two or more case costs that were are effective <= GETDATE(). I can sort it by effective date (DESC) so I know the first of every UPC in my results will be the current effective case cost, but how do I modify my query so that in my result set I only get the first of every UPC?

Here is my query:

SELECT factCaseCosts.nUpcKey, factCaseCosts.dCaseCost, factCaseCosts.dtEffectiveDate
FROM factCaseCosts
WHERE (factCaseCosts.dtEffectiveDate <= GETDATE())
ORDER BY dtEffectiveDate DESC

Here is my current result set:
52023.762006-08-01 00:00:00
52023.762006-02-18 00:00:00
52123.762006-08-01 00:00:00
52123.762006-02-18 00:00:00
52230.362006-08-01 00:00:00
52230.362006-02-18 00:00:00
52323.762006-08-01 00:00:00
52323.762006-02-18 00:00:00

I only want the first 520 returned, the first 521 returned, the first 522 returned, and the first 523 returned.
How can I do this?
Thanks!

Embedded Select Distinct Query

Feb 18, 2015

This is part of a query I have. I want to display the diagnosis code attached to a patient. Sometimes there are more than one which is why I have tried distinct. I am getting the message 'subquery returned more than 1 value...'

If I use MIN or MAX, its giving me the min possible diagnosis code alphabetically or the max, not the one actually assigned to the patient which is what I want.

(SELECT DISTINCT (Diagnosis.DiagnosisCode) FROM Diagnosis
LEFT OUTER JOIN CourseDiagnosis ON CourseDiagnosis.DiagnosisSer = Diagnosis.DiagnosisSer
LEFT JOIN Course ON Course.CourseSer = CourseDiagnosis.CourseSer
JOIN Patient ON Patient.PatientSer = Course.PatientSer
WHERE Diagnosis.ObjectStatus = 'Active' AND
Diagnosis.Description not like 'ERROR%' AND
Diagnosis.DiagnosisTableName not in ('RTDS Dates')),

i looked in all kinds of SQL tutorials and nothing came up so i came here, tnx for your help!.

How To Use ORDER BY Clause In An SELECT DISTINCT Sql Query When AS SINGLECOLUMN Is Defined?

Mar 22, 2008

Hi,
I wonder if its possible to perform a ORDER BY clause in an SELECT DISTINCT sql query whereby the AS SINGLECOLUMN is used. At present I am recieving error: ORDER BY items must appear in the select list if SELECT DISTINCT is specified. My guess is that I cant perform the Order By clauses because it cant find the columns individually. It is essentail I get this to work somehow...
Can anyone help? Thanks in advance

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?

SQL Server 2012 :: Using Unions To Write Out Each Select Query As Distinct Line In Output

Aug 20, 2015

Basically I'm running a number of selects, using unions to write out each select query as a distinct line in the output. Each line needs to be multiplied by -1 in order to create an offset balance (yes this is balance sheet related stuff) for each line. Each select will have a different piece of criteria.

Although I have it working, I'm thinking there's a much better or cleaner way to do it (I use the word better loosely)

Example:
SELECT 'Asset', 'House', TotalPrice * -1
FROM Accounts
WHERE AvgAmount > 0
UNION
SELECT 'Balance', 'Cover', TotalPrice
FROM Accounts
WHERE AvgAmount > 0

What gets messy here is having to write a similar set of queries where the amount is < 0 or = 0

I'm thinking something along the lines of building a table function contains all the descriptive text returning the relative values based on the AvgAmount I pass to it.

Difficult Query: Is This Possible In SQL?

Jul 20, 2005

suppose I have the following table:CREATE TABLE (int level, color varchar, length int, width int, heightint)It has the following rows1, "RED", 8, 10, 122, NULL, NULL, NULL, 203, NULL, 9, 82, 254, "BLUE", NULL, 67, NULL5, "GRAY", NULL NULL, NULLI want to write a query that will return me a view collapsed from"bottom-to-top" in order of level (level 1 is top, level 5 is bottom)So I want a query that will returnGRAY, 9, 67, 25The principle is that looking from the bottom level up in each columnwe first see GRAY for color, 9 for length, 67 for width, 25 forheight. In other words, any non-NULL row in a lower level overridesthe value set at a higher level.Is this possible in SQL without using stored procedures?Thanks!- Robert

Difficult T-SQL Query (for Me Anyways)

Nov 13, 2006

Hi.

I am developing for a system that receives an input from an external modem.

The Transaction is split into 2 sections,

Section 1 = grants the transaction ID,

Section 2 = deliver the transaction Data.

I have 2 corresponding tables,

One called tblremoteunitrequestID (Where the transaction ID is granted)

The other called tblremoteunitrequests (Where the transaction is completed, about 1 second later)

I am writing a diagnostic report that determines if the first part of the transaction completes but the second part fails.

I am having difficulties designing the SQL for this.

Here is some sample data for tblremoteunitrequestID: (The first stage of the transaction)

RecordDate | Serial

13/11/2006 14:00:36 0000-0000-0000-0006
13/11/2006 14:00:30 0000-0000-0000-0004
13/11/2006 13:59:04 0000-0000-0000-0092 (This didtn transaction didnt complete)
13/11/2006 12:15:22 0000-0000-0000-0092 (nor did this one)
13/11/2006 10:31:54 0000-0000-0000-0092
13/11/2006 10:00:29 0000-0000-0000-0006

Here is some sample data for tblremoteunitrequests: (The second stage of transaction, 1st stage has to be completed beforehand)

DateReceived | Serial

13/11/2006 14:00:37 0000-0000-0000-0006
13/11/2006 14:00:31 0000-0000-0000-0004
13/11/2006 10:31:56 0000-0000-0000-0092
13/11/2006 10:00:31 0000-0000-0000-0006
13/11/2006 10:00:25 0000-0000-0000-0004
13/11/2006 07:19:13 0000-0000-0000-0020

From this data I can see that serial number 0000-0000-0000-0006 Successfully completed part 1 and part 2 of the transaction, as did serial number 0000-0000-0000-0004.

Serial number 0000-0000-0000-0092 had trouble, it connected at 13:59:04 (tblremoteunitrequestID) but part 2 didnt complete, so it wasent saved in tblremoteunitrequests. The same happened at 12:15:22 but at 10:31:54 it was successful so it was saved.

I Only want to display the transactions that didnt complete, sounds easy huh?

This is what I hope to get in my Results table:

DateReceived | Serial

13/11/2006 13:59:04 0000-0000-0000-0092
13/11/2006 12:15:22 0000-0000-0000-0092

I was experimenting with T-SQL today, this is what I have done so far:

SELECT DISTINCT
TBLRemoteFeildUnitRequestID.Serial, TBLRemoteFeildUnitRequestID.RecordDate,

CASE WHEN TBLRemoteUnitRequests.DateReceived BETWEEN DATEADD(SECOND,-1,TBLRemoteFeildUnitRequestID.RecordDate) AND DATEADD(SECOND,10,TBLRemoteFeildUnitRequestID.RecordDate)

THEN ' Ok'

ELSE ' Not ok'

END AS PROBLEM

FROM TBLRemoteFeildUnitRequestID LEFT OUTER JOIN
TBLRemoteUnitRequests ON TBLRemoteFeildUnitRequestID.Serial = TBLRemoteUnitRequests.Serial
WHERE TBLRemoteFeildUnitRequestID.RecordDate BETWEEN DATEADD(WEEK, - 2, GetDate()) AND GetDate()

ORDER BY RecordDate DESC

This kinda worked, but it caused records that satisfied the between condition to be displayed twice, once as "Ok" and once as "Not ok".

Heres a sample of the result I got:

Serial | RecordDate (1st part of transaction) | Status

0000-0000-0000-0006 2006-11-13 14:00:36.000 Ok (Duplicated)
0000-0000-0000-0006 2006-11-13 14:00:36.000 Not ok
0000-0000-0000-0004 2006-11-13 14:00:30.000 Not ok (Duplicated)
0000-0000-0000-0004 2006-11-13 14:00:30.000 Ok
0000-0000-0000-0092 2006-11-13 13:59:04.000 Not ok (Correct) (Not duplicated)
0000-0000-0000-0092 2006-11-13 12:15:22.000 Not ok (Correct) (Not Duplicated)
0000-0000-0000-0092 2006-11-13 10:31:54.000 Not ok (Duplicated)
0000-0000-0000-0092 2006-11-13 10:31:54.000 Ok
0000-0000-0000-0006 2006-11-13 10:00:29.000 Ok (Duplicated)
0000-0000-0000-0006 2006-11-13 10:00:29.000 Not ok


I have just about had enough, I have wasted an entire day on this

Difficult Query With Many-To-Many Relationship

Sep 20, 2007

I'm writing a workflow management application for my work, and its somewhat complicated, here's a general idea of how it works:

- Anything that a company does is defined by a workflow.
- A workflow consists of tasks.
- Some tasks in a workflow can't be started until other tasks have been completed. If task A can't be started until tasks B and C are finished, then task A depends on B and C.

You might imagine that a bank has a workflow for handling a house loan. Before a bank could sign a contract with an applicant, they'd need proof of house ownership, but before they could get proof of house ownership they need an applicant's proof of identity like a driver's license or military ID.

Here's an oversimplified visual:

Each arrow points to its dependency. Each task can have multiple dependencies.

The setup above is represented in the database by a Tasks and a Dependencies table. Tasks has an ID field, and Dependencies has a TaskID and DependencyID field which are both foreign keys to Tasks.ID.

Code:

[Tasks]
ID Status Name
-- ------ ----
1 Done Start Processing Loan Application
2 Done Photocopy applicant's driver's license
3 NotDone Photocopy proof of house ownership
4 NotDone Get a copy of applicant's W-2 forms
5 NotDone Perform credit check on applicant
6 NotDone Sign loan contract


[Dependencies]
TaskID DependencyID
------ ------------
1 0
2 1
3 1
4 2
5 2
5 3
6 4
6 5


Tasks has a many-to-many relationship with itself.

Here's the hard part:
- A task can't be started until all of its dependencies have been completed.
- after a task is completed (meanings its status is marked "done"), I need to return a list of all the new tasks that are ready to be started.

When TaskID 2 is marked "Done", then TaskID 4 is ready to begin; however, TaskID 5 is not ready to begin since it depends on 2 and 3, and 3 hasn't been completed yet.

The requirements of the query are very simple, but the implementation is difficult.


I'll post a prelimenary solution in the next post:

Difficult Summing Query

Nov 23, 2005

Hello,Here is a brief summary:Table 1 = All Accounts- with fields such as Customer ID and Account #Table 2 = Deposit Balance Table- with fields such as Account #, BalanceTable 3 = Loan Balance Table- with fields such as Account #, BalanceAll accounts are either deposit accounts or loan accounts. What I needto do is to gather information about total balances in both depositsand loans for each customer. I haven't been able to hit the right queryfor doing this. I can easily get information about one or the other,such as the following:SELECT All_Accounts.Customer_ID, COUNT (DISTINCT(Deposit_Balance_Table.Account_Number)), Sum(Deposit_Balance_Table.Balance)FROM Product_Table, Deposit_BalanceWHERE (Product_Table.Account_Number=Deposit_Balance.Acco unt_Number)GROUP BY Product_Table.Customer_ID ORDER BY 1Which will give me one row for each user, and show me the total numberof deposit accounts each customer has and a sum of the balances in eachof those accounts. I can make a similar query involving Loan Accounts.As soon as I try to draw both, however, I wind up below my depth.Something to do with the handedness of my joins, I believe. Often Iwill get one column of information (either deposits or loans), or thequery will fail because the join I'm attempting is invalid, etc. I needto take every row in the All_Accounts table, match each one to itsbalance in either the Deposit or Loan table, and then group them all bythe Customer ID and sum them, so that I can find out the totalrelationship balance per customer. Any help would be appreciated.

Learning SQL: Rather Difficult Query Needed: And If You Know This With Explanation What You're Doing If Possible :)

Difficult Query: Return Recordset From Concatenated Strings?

Jul 20, 2005

Hi All,I have what seems to me to be a difficult query request for a databaseI've inherited.I have a table that has a varchar(2000) column that is used to storesystem and user messages from an on-line ordering system.For some reason (I have no idea why), when the original database wasbeing designed no thought was given to putting these messages inanother table, one row per message, and I've now been asked to providesome stats on the contents of this field across the recordset.A pseudo example of the table would be:custrep, orderid, orderdate, comments1, 10001, 2004-04-12, :Comment 1:Comment 2:Comment 3:Customer askedfor a brown model2, 10002, 2004-04-12, :Comment 3:Comment 4:1, 10003, 2004-04-12, :Comment 2:Comment 8:2, 10004, 2004-04-12, :Comment 4:Comment 6:Comment 7:2, 10005, 2004-04-12, :Comment 1:Comment 6:Customer cancelled orderSo, what I've been asked to provide is something like this:orderdate, custrep, syscomment, countofsyscomments2004-04-12, 1, Comment 1, 12004-04-12, 1, Comment 2, 22004-04-12, 1, Comment 3, 12004-04-12, 1, Comment 8, 12004-04-12, 2, Comment 1, 12004-04-12, 2, Comment 3, 12004-04-12, 2, Comment 4, 22004-04-12, 2, Comment 6, 22004-04-12, 2, Comment 7, 1I have a table in which each of the system comments are defined.Anything else appearing in the column is treated as a user comment.Does anyone have any thoughts on how this could be achieved? The endresult will end up in an SQL Server 2000 stored procedure which willbe called from an ASP page to provide order taking stats.Any help will be humbly and immensely appreciated!Much warmth,Murray

Trying To Add A NON-DISTINCT Field To A DISTINCT Record Set In A Query.

Mar 12, 2007

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

Select Not Distinct?

Apr 8, 2008

Is their a way to select all items from a table that are not distinct? Meaning, I want to know which items in a column occur more than once.
Example: 
Suppose we have a table with student names, ss# and address. I want to display only records where their is more than one studen with the same name. So for example their could be ten people with the name of "Mike" in a class?

Select Distinct

Feb 15, 2000

Hi! I have 4 tables and they have a common column (eg. regionid). These
4 tables have data overlapping with the others. Some data exist in a table
but not on the others. What I want to do is to do a select that will display
all distinct regionid from these tables. It should be total of all the tables but will suppress any duplicates with the others.

Note that UNION is working but I can't use that. Why ? because UNION is not supported or maybe not working properly with RDB database. I'm doing an appliaction for heterogenous datasource.

Any tips, hints or info will be appreciated.
thanks in advance.

Does anyone know why this does not work?

SELECT DISTINCT tb2.column20 tb2.column20, tb1.column10, tb2.column21, tb2.column22, tb3.column30
FROM table1 tb1, table2 tb2, table3 tb3
WHERE tb1.column11 = 'P'
AND tb2.column23 = 'P'
AND tb1.column12 = tb2.column24
AND tb2.column25 = tb3.column31
ORDER BY tb2.column20

Its supposed to return only the distinct entries in tb2.column20

Select Distinct Help?

Jan 19, 2005

Can you have "Select Distinct" in Union Query,because that is what I am trying to do and this is the error message I get.

"The text, ntext, or image data type cannot be selected as DISTINCT."

I would need to do that because i have duplicate records,because these records are getting written into the db when templates are generated and sometimes if they double click it generates two and writes that many results as well, so that is why I was thinking that select distinct would solve my problem.


Thanks for your help

This is the query in question:

((SELECT TOP 1 ExchangeRateToUSD

Hi,

I wonder if anyone here can shed some light on why the query below produces duplicate EmailAddress values even though we specify the DISTINCT clause.

SELECT DISTINCT(EmailAddress) SubscriberID, FirstName, Surname, SubscriberID
FROM TestMailingList
ORDER BY EmailAddress

Thanks.

Help With A Distinct Select?

May 10, 2006

Hi,

I am new to this forum so hello to everyone!

I need some help getting unique records from a query, I have a large amount of nested selects and i want to only display distinct records, I have a unique identifier (party ID) but the code was written by someone else (who is on holiday!) and i need to work out where to insert the disctinct select (if at all? - open to a better way?) this query should pull back records and then the results are pasted in to excel, however would a DTS solve the issue with duplicates??

Any help more than appreciated!

Heres the code...

SELECT DISTINCT

Oct 16, 2006

Hello,

When I try the SELECT DISTINCT like this:


USE CHEC

SELECT DISTINCT
[DATE_CONVERSION_TABLE_NEW].MONTH,
DAY([DATE_CONVERSION_TABLE_NEW].[DISBURSEMENT DATE]) AS DayofMonth,
DAT01.[_@550] AS LoanType,
DAT01.[_@051] AS Branch,
DAT01.[_@TP] AS ProdTypeDescr,
SMT_Branches.[BranchTranType] AS TranType,
--SMT_Branches.[AUCode] AS AuCode,
COUNT(*) AS Totals
FROM DAT01 INNER JOIN [DATE_CONVERSION_TABLE_NEW]
--ON DAT01.[_@040] = [DATE_CONVERSION_TABLE_NEW].[DISBURSEMENT DATE]
ON DAT01.[_@040] = [_@040]
INNER JOIN SMT_BRANCHES
ON SMT_Branches.[BranchTranType] = SMT_BRANCHES.[BranchTranType]
WHERE
DAT01.[_@040] Between '06/01/2006' And '06/30/2006'
And SMT_BRANCHES.[BranchTranType] = 'RETAIL'
AND DAT01.[_@051] = '540'
--And SMT_Branches.[AUCode] = '1882'
And DAT01.[_@TP] = '115'
And DAT01.[_@550] = '3'
GROUP BY
DAT01.[_@051],
DAT01.[_@550],
DAT01.[_@TP],
SMT_Branches.[BranchTranType],
--SMT_Branches.[AUCode],
[DATE_CONVERSION_TABLE_NEW].MONTH,
DAY([DATE_CONVERSION_TABLE_NEW].[DISBURSEMENT DATE])
ORDER BY [DATE_CONVERSION_TABLE_NEW].MONTH,
DAT01.[_@051],
DayofMonth ASC
--SMT_Branches.[AUCode] ASC
--COMPUTE sum(count(*))


I get the same result set as before.

What do I need to change?

Kurt
