How To Use ORDER BY Clause In An SELECT DISTINCT Sql Query When AS SINGLECOLUMN Is Defined?
Mar 22, 2008Hi,
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

Trying To Use The Results Of A Case Statement In My Select List In My WHERE Clause?
Aug 10, 2006I am fairly new with SQL and still learning. I have used a case statemtent for a column in my select list and want to use the results of that statement's field in my WHERE clause but it is not working for me. Here is the code I have so far:
SELECT
l.loanid,
p.investorid,
l.duedate,
case when pc.duedate >= l.duedate then pc.duedate end as RateDueDate,
pc.interestrate
FROM loan l
inner join participation p on p.loanid = l.loanid
inner join paymentchange pc on pc.loanid = l.loanid
where p.investorid = '12345' and RateDueDate is not null
order by l.loanid, pc.duedate
I want to put the results of this case statment in my where clause like highlighted above but it is not working because RateDueDate is not an actual column in the table. Any help would be greatly appreciated.
Thanks!

Jul 6, 2007Hi, 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?
Filtering Results In The Where Clause Vs A Having Clause
Oct 25, 2007I am working with a vendor on upgrading their application from SQL2K to SQL2K5 and am running into the following.
When on SQL Server 2000 the following statement ran without issue:
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
GROUP BY TrackID
HAVING MAX(LegNum) = 1 AND
TrackID + 'x1' IN
(
SELECT
dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
)
Once moved to SQL Server 2005 the statement would not return and showed SOS_SCHEDULER_YIELD to be the waittype when executed. This machine is SP1 and needs to be upgraded to SP2, something that is not going to happen near time.
I changed the SQL to the following, SQL Server now runs it in under a second, but now the app is not functioning correctly. Are the above and the following semantically the same?
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
WHERE TrackID + 'x1' IN
(
SELECT dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
GROUP BY TrackID
HAVING MAX(LegNum) = 1
)

View 3 Replies View RelatedWhen Does Ssrs Use A DISTINCT Clause In It's Queries?
Jun 27, 2007I am having a heck of a time figuring out what controls how/when the generated SQL for a report puts a DISTINCT clause in front of it.
For instance, not that this report makes any sense, but I have 58 rows in my fact table/entity €“ If I pull in a lookup field and execute, the distinct is put in the query and I basically get a list of the possible domain values. It runs the whole joined table query to get them, but it does list (in this case) just 4 records. Now I put in the primary ID of the fact entity and the distinct goes away and I get my 58 rows. If I put two lookup fields, the DISTINCT is back. If I pull in the description field (text string just a direct source field mapping not part of the identifying attributes), the distinct is there. If I pull in the Company Name field on a different entity (which is essentially the same as pulling in Description only it is part of the identifying attributes), there is no DISTINCT. I can pull in all my fields on this entity and none of them drive the distinct. And I swear (ok, I am probably lying but not on purpose) the field/attribute and roles properties are all the same on the attributes. But you get my general question/situation...
Any insight for me? Does it have to do with how I am building the report rather than the underlying model?
Thanks in advance,
DISTINCT Results Based On The Value Of One Col?
Jun 19, 2008Here's one thats had me and a coworker puzzled. Hopefully it's something simple:
TABLE A: (log of messages)
userid, int
date, datetime
message, varchar(50)
Table A Data:
1, 6/18/2008 @ 2:32:41, This is my message
1, 6/18/2008 @ 2:31:02, This is my message
1, 6/17/2008 @ 7:34:26, This is another message
2, 6/18/2008 @ 2:32:41, This is not his message
2, 6/16/2008 @ 11:21:32, This is my message
TABLE B: (List of users)
userid, int
name, varchar(100)
Table B Data:
1, John
2, Mike
I want to extract the most recent message logged per user, i.e.:
name | date | message
--------|---------------------|-------------------------
John | 6/18/2008 @ 2:32:41 | This is my message
Mike | 6/18/2008 @ 2:32:41 | This is not his message.
I have been unable to come up with a query that can return just the one value. I've tried variants of:
SELECT DISTINCT b.name, a.date, a.message
FROM a INNER JOIN
b ON a.userid = b.userid
including sub-queries and even played with the visual diagrams trying to design this in Enterprise Manager but none of the combinations I tried work. Is there an easy way to do this via a query? I don't have experience with stored procedures. Would that be necessary?
TIA
Not Getting Distinct Results With Inner Join
Mar 5, 2007Hello, first post since I can usually find answers by reading the forums. I've searched the internet up and down and for some reason I can't get this query to work properly.
I have two tables:
ticket
ticket_id
ticket_to
ticket_from
message
message_id
ticket_id
message
There can be several messages per ticket, connected by the ticket_id. I'd like to only pull only the most recent message, as well as the results from the ticket table. Currently I'm getting all messages per ticket.
Here's what I have:
SELECT distinct ticket.ticket_to, ticket.ticket_from, message.ticket_id, message.message
FROM tickets
INNER JOIN message ON tickets.ticket_id = message.ticket_id
GROUP BY message.ticket_id, message, ticket_to, ticket_from
Any help would be greatly appreciated! Thanks much.

Displaying Distinct Results From Union Query
Aug 31, 2000I've got a union query (below)and it returns rows that have duplivate itemno's, descrip's, imsrp3's, and imsrp4's, while the remaining columns are not duplicate for the same row. An Excel report uses this query to populate itself and for a more visually appealing look, I'd like to skip the duplicated columns in the display. I'm not sure how to use the Distinct or Group by in this case, since technically I'm dealing with two separate queries, neither one separately returning any duplicate rows.
thanks for any suggestions...

Extract Distinct Information And Order The Results
Sep 24, 2007Hi,
MSSQL 2000 T-SQL
I have a problem in extracting information pertaing to a key value and matching that key value to another transaction but the order is based on another value in the same row.
I've attached a sample of DB data below.
tran_nr ret_ref_no msg_type description
5111 12345 420 reversal
5112 12345 200 auths
5113 15236 200 auths
5114 46587 200 auths
5115 46587 420 reversal
Requirement using the above data is to extract data where the ret_ref_no is the same for more than one row but also check that the msg_type 420 happens before the 200. Is there a way of retrieving the information in this way using the tran_nr coloumn values? The tran_nr values is basically the serial number when the transaction is wrriten away to the DB.
I've managed only to retrive the 1st half of my query whereby the same ret_ref_nr is being used by more then one transaction. Still need to figure out the 2nd part where the msg_type of 420 happens before the 200.
SELECT * FROM SAMPLE
WHERE ret_ref_no in
(
SELECT ret_ref_no FROM SAMPLE
GROUP BY ret_ref_no HAVING COUNT(*) > 1
)
Results of query
5111 12345 420 reversal
5112 12345 200 auths
5114 46587 200 auths
5115 46587 420 reversal
If someone could assist with only retreiving the above results in bold to the query analyser i will really appreciate it.

Is It Possible To Re-reference A Column Alias From A Select Clause In Another Column Of The Same Select Clause?
Jul 20, 2005Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

Rank() And Using WHERE Clause On Results
Oct 25, 2006Hi,
I am trying to return the 100th ranking in my SQL, ie
SELECT DailyValueChange, BUSINESS_DATE, RANK() OVER (order by DailyValueChange) AS RANK_Vals
FROM Table
WHERE (BUSINESS_DATE = @CurrentBusDate) AND (RANK_Vals = 100)
However when I try to update the Stored Procedure it tells me RANK_Vals is an invalid column name, which is not the case as if I run it without the Where clase it runs and returns all results.
Any advice on how to get around this would be greatly appreciated.

SQL7: Order Of Values In IN Clause Affects Results
Dec 14, 1999Hi!
Has anyone experienced this problem?
Certain queries that work fine in SQL 6.5 and Oracle return inconsistent / inaccurate results in SQL 7 (with SP1). These queries include an IN clause with a range of values.
For example, the following query:
SELECT columnA, columnB, columnC, columnD
FROM table
WHERE columnD = 'I'
AND columnA IN (1,2,3,11,19)
go
returns a different result than this query:
SELECT columnA, columnB, columnC, columnD
FROM table
WHERE columnD = 'I'
AND columnA IN (1,3,11,2,19)
go
The only way we have stumbled upon to get accurate results consistently is to order the range values from largest to smallest:
AND columnA IN (19,11,3,2,1)
Have not seen this documented anywhere. We are in the process of re-ordering these ranges in our code, but I welcome any ideas or comments...
Thanks!
WHERE Clause Boolean - Different Results Depending On Entered Parameter
Jan 13, 2015This is for Microsoft Server SQL 2012.
I'm trying to create a WHERE clause that will have different results depending on a parameter that is entered. For example, if you put in a number, it will only calculate the rows where the column ID matches that number. However, if you put in 0, which doesn't exist in that column ID, it will instead calculate all the data in the table.
So the below would be a very basic idea of what I'm trying to do, but I'm not sure how to do it with proper syntax.
WHERE IF ID=0, THEN do this
ELSE do this AND ID=#
Expression Defined In SELECT Clause Overwrites Column Defined In FROM Clause
May 14, 20082 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16

union select 11 id
) v

Apr 8, 2008Is 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, 2000Hi! 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.
