Retrieve Distinct Rows From Select Statement
Jan 10, 2014
Is it possible to retrieve Distinct rows from this Select Statement?
I'm getting the correct results, but duplicate rows because some customers place more than one order on the same day.
Code:
SELECT dbo.Customers.CustomerID, dbo.Customers.Title, dbo.Customers.FirstName, dbo.Customers.LastName, dbo.Customers.CustomerEmail, dbo.Customers.DateCreated,
CONVERT(char, dbo.Customers.DateCreated, 103) AS [DD/MM/YYYY], dbo.loyalty_points.LPoints, dbo.Orders.OrderID
FROM dbo.Customers INNER JOIN
dbo.loyalty_points ON dbo.Customers.CustomerID = dbo.loyalty_points.CustomerID INNER JOIN
dbo.Orders ON dbo.Customers.CustomerID = dbo.Orders.CustomerID
WHERE (CONVERT(char, dbo.Customers.DateCreated, 103) = CONVERT(char, GETDATE() - 6, 103))

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?

Hi,
I'm having a little bit of trouble trying to figure out how to do this query, right now I have:
SELECT I.AppItemId, P.ProductID, P.PartNum, P.Relist, I.AppUserId
FROM ProductsToRelist I join Products P on P.ProductID = I.AppSKU
WHERE P.Relist = 1 and I.AppStatus = 5 and Not I.AppItemId is Null
and it returns something like this:
AppItemId ProductID PartNum Relist AppUserId
2786 -32730 SELECT_OOS11
2787 -32729 SELECT12
2788 -32727 SELECT_OOS11
4269 -30987 SELECT_OOS12
1665 -30987 SELECT_OOS11
2433 -30987 SELECT_OOS11
4272 -30984 SELECT11
2436 -30984 SELECT11
2793 -32708 SELECT11
But I only it want it to return 1 record for each ProductID like so:
AppItemId ProductID PartNum Relist AppUserId
2786 -32730 SELECT_OOS11
2787 -32729 SELECT12
2788 -32727 SELECT_OOS11
4269 -30987 SELECT_OOS12
4272 -30984 SELECT11
2793 -32708 SELECT11
ProductID is the primary key for the Products table, and a product can be in the ProductsToRelist table many times but each row would have a unique AppItemId. I know that I need to use Distinct or a different kind of join, but I'm not sure which. How would you suggest to do this?
Thanks

I have the following tablecolumns: [col1], [col2],[col3] and [NAME].I want to select the name column for each row where [col1]='07'.The problem is that there are several rows where [col1] contains '07' and also the name is the same. [col2] and [col3] contain different data for these double rows...however, I cant use the [col1] and [col2] values in my query because I dont know what values they contain beforehand.So now, when I execute my query and add the DISTINCT key I still get all the double rows!I hope this explains my problem, help is really appreciated...ow, btw: deleting the double rows is not an option....

Hey there, is there a way I can use command such as distinct in a select statement to do the following. Lets say I want to do a search of products based off their location and I want to list the companies that will have products in that area. I only want to list the company once, but if I’m searching by products in the area I might come up with 15 results for that company. I have not written the code yet for this, I’m just planning ahead.
I’m programming using VB so I guess I would do something like this.
State = Trim(Request.QueryString("State"))
SelectStatement = "Select * From Products Where State='" & _
State & "'"
This would of course give me hypothetically speaking a list as long as the amount of products in one given area. Is there a way to cut this down and only list the company once? Any help would be greatly appreciated. Thanks in advance.

Hello everyone, I'm working on a SQL statement that I "thought" worked fine until I noticed I was getting a duplicate row. Below is the SQL statement from the stored procedure: SELECT DISTINCT number AS 'RteNum', leg_orig AS 'Origin',
leg_dest AS 'Dest', AcEquipment.EquipmentDesc AS 'EquipType',
SUBSTRING(trailer_option, 1, 1) AS 'TrailerOption',
leg_depart_time_local AS 'DeptTime',
leg_arrive_time_local AS 'ArrTime',
dev.fnConvertEffectiveDaysToDaysOfWeek(SUBSTRING(leg_effective_local, 2 ,7)) AS 'EffectiveDays',
TruckEditor.EffectiveDays as 'NewEffectiveDays'
FROM lhif_prod
JOIN AcEquipment ON AcEquipment.EquipmentType = lhif_prod.Equipment_Type
LEFT JOIN dev.TruckEditor ON TruckEditor.Origin = lhif_prod.leg_orig AND TruckEditor.Dest = lhif_prod.leg_dest
AND TruckEditor.RouteNum = lhif_prod.number AND TruckEditor.DeptDate = lhif_prod.leg_depart_date_local
WHERE leg_depart_date_local BETWEEN @DateStart AND @DateEnd
AND Type_Code = 'T' AND leg_orig = @LocID
ORDER BY RteNum, Dest, DeptTime Here is what comes back from this query:ABE00 ABEA ABER CTV5 H 1855 1915 MTWT--- NULLABE01 ABEA ABER CTV5 H 1941 2001 MTWT--- NULLABE02 ABEA ABER CTV5 H 2045 2105 MTWTF-- NULLABE03 ABEA ABER CTV5 H 2059 2119 MTWTF-- NULLABE04 ABEA ABER CTV2.5 H 2245 2305 MTWTF-- NULLABE11 ABEA ABER WALKIN H 2045 2100 MTWTF-- NULLABE11 ABEA ABER WALKIN H 2045 2100 MTWTF-- MT-TF--ABE12 ABEA ABER WALKIN H 2109 2124 MTWTF-- NULLEF038 ABEA EWRHB 53BULK H 0100 0245 -TWTFS- NULLEF085 ABEA EWRHA CTV5 H 1955 2140 MTWT--- NULLEF106 ABEA EWRHB CTV5 H 1901 2046 -----S- NULLEF140 ABEA ABER CTV5 H 0550 0610 M------ NULLEF166 ABEA EWRRA CTV5 H 2230 0010 MTWT--- NULLEF366 ABEA EWRRA CTV5 H 2230 0010 ----F-- NULLEF543 ABEA EWRRA CTV5 H 2200 2345 MTWTF-- NULL The 2 rows in bold are the issue right now. There should only be 1 row (the 2nd one where the last column is not null). I'm not sure why it returns both columns when I'm doing a join on there to add that last column. Can anyone help me out with this? I'm not very strong in SQL, so if I'm overlooking something, I'd appreciate any help you can provide. Thanks.

Hey,
I am not sure how to really explain this, but I'll give it a try.
I am looking to use a select statement in a way that I can tell it which rows to insert in depending on when only one result is returned. For example, if I run this statement:
SELECT Column1, Column2, Column3
FROM #Temp1
The result set is:
Column1---Column2---Column3
99--------6756756---55555
44--------55---------NULL
Column3 as only the one returned value, so I do not want it associated with any of the other rows, so I need this:
Column1---Column2---Column3
NULL------NULL------55555
99--------6756756---NULL
44--------55---------NULL
Another example:
The returned result now is:
Column1---Column2---Column3---Column4
99---------6756756---55555-----NULL
42---------55---------NULL------12345
So I need:
Column1---Column2----Column3----Column4
NULL-------NULL-------55555------NULL
NULL-------NULL-------NULL-------12345
99---------6756756----NULL-------NULL
44---------55----------NULL-------NULL
Does this make sense, and/or is it even possible?
I know it could be more of a presentation thing, but I would like to know how to do it in the code behind.
Thanks

I need some help with a query . I have two tables "config" and "item".
I have table config as follows:
ConfigID
ItemID
With Values
ConfigID ItemID
14583 2776
14583 2798
14583 3112
And table item as follows:
ItemID
ItemTypeID
ItemValue
With Values
ItemID ItermTypeID ItemValue
2776 1 123
2798 2 ABC
3112 3 789
So the query:
SELECT ConfigID,
(SELECT ItemValue WHERE ItemTypeID = '1') AS Model,
(SELECT ItemValue WHERE ItemTypeID = '3') AS Minor,
(SELECT ItemValue WHERE ItemTypeID = '2') AS Customer
FROM config c, item i
WHERE ConfigID = '14583'
AND c.ItemID = i.ItemID
Produces the result:
ConfigID Model Minor Customer
14583 123 NULL NULL
14583 NULL NULL ABC
14583 NULL 789 NULL
How do I change the above query to get one row:
ConfigID Model Minor Customer
14583 123 789 ABC
Thanks for your help

Hello all,
I am trying to select a specific amount of rows from an AS400 table and when I do so it only shows a specific amount of rows regardless of how many there actually is. If we run it multiple times, it displays the same amount of rows. We went into the iSeries ODBC and changed the timeout setting and the Record Blocking Size (increased it) and it did pull more rows but still not what we were looking for. We suspect it has something to do with pulling the specific amount of blocks and instead of continue to pull, it stops when it reaches the first blocking limit. I can however pull the information through MS Access with the same settings. The query we are using to pull the information is
Select * Into Table From Openquery(AS400,'Select * From Tablename')
Was wondering if anyone has seen this before and if so if they found a fix so we can pull everything we are looking for.
Thanks!

I wonder how to get top 1 row per account number. Let's say I have
--snip--
IDENTITY_ID | ACCT_NUMBER
0001 | 1111-2222
1001 | 1111-2222
2002 | 2222-0000
3003 | 2222-0000
4004 | 1111-2222
--snip--
I used the SQL-Query here
Code:
SELECT * FROM BACKUP_LOG ORDER BY IDENTITY_ID DESC
[code]
Since they are in descending order by IDENTITY_ID, so I only want to get 1 distinct account number somehow.. Like this...
[code]
4004 | 1111-2222
3003 | 2222-0000
I couldn't figure it out.

Is there a way to build a select statement that will output related rows with different column data per row? I want to return something like:
rowtype| ID | value
A | 123 | alpha
B | 123 | beta
C | 123 | delta
A | 124 | some val
B | 124 | some val 2
C | 124 | some val 3
etc...
where for each ID, I have 3 rows that are associated with it and with different corresponding values.
I'm thinking that I will have to build a temp table/cursor that will get all the ID data and then loop through it to insert each rowtype data into another temp table.
i.e. each ID iteration will do something like:
insert into #someTempTable (rowtype, ID, value) values ('A', 123, 'alpha')
insert into #someTempTable (rowtype, ID, value) values ('B', 123, 'beta')
insert into #someTempTable (rowtype, ID, value) values ('C', 123, 'delta')
etc..
After my loop, I will just do a select * from #someTempTable
Is there a better, more elegant way instead of using two temp tables? I am using MSSQL 2005

I have created a trigger that is set off every time a new item has been added to TableA.The trigger then inserts 4 rows into TableB that contains two columns (item, task type).
Each row will have the same item, but with a different task type.ie.
TableA.item, 'Planning'
TableA.item, 'Design'
TableA.item, 'Program'
TableA.item, 'Production'

Hi,
I want to select the 8 most saled products from large orders table... the problem is that when i use the "distinct" sentence (something like this- "SELECT TOP 8 distinct id, products, productid FROM tbl_orders ORDER BY id") I get back the distinct of any columns.... (and any ID is distinct, of course), but if i don't include the id's in the distinct sentence, i can't order by id's.
can i get the last orders, only by distinct product, and not by distinct id, and order them by the id's?

I'm trying to return a select statement with distinct values. I have 3
tables: Documents, DocumentAuthors and the linking table
DocumentAuthorsRel. Since a document can have multiple authors, the
DocumentAuthorsRel table holds the DocumentID and DocumentAuthorID
values.
I simply want to run a query which displays a list of
all the document titles (no document title should be repeated, i only
want to show the title once, distinct) held in the documents table, and
with the document title, show the last names of a documents author(s).
This
is the statement Im using which is returning duplicated document titles
(as a result of a document having multiple authors - found in the
DocumentAuthorsRel table)
SELECT Documents.DocumentID, Documents.Title, DocumentAuthors.AuthorLName
FROM DocumentAuthors INNER JOIN
DocumentAuthorsREL ON DocumentAuthors.DocumentAuthorID = DocumentAuthorsREL.DocumentAuthorID INNER JOIN
Documents ON DocumentAuthorsREL.DocumentID = Documents.DocumentID
Any help would be appreciated.

I am trying to retrieve all rows with the largest value in a particular column. The largest value could return many rows for a particular users. Here is what I have thus far.
SELECT DISTINCT
ID, NAME, FOP, ACCT, CTNUM, ENDDATE, DEBIT, CREDIT, TRANSACTION_DATE, EXPORTED, CALENDAR_YEAR, FISCAL_YEAR, PAYROLL_IDENTIFIER,
PAYROLL_NUMBER, [EARN-SEQNO], EVENT_SEQUENCE_NUMBER
FROM (SELECT *, ROW_NUMBER() OVER (PARTITION BY ID, ACCT, PAYROLL_NUMBER,EVENT_SEQUENCE_NUMBER
ORDER BY EVENT_SEQUENCE_NUMBER DESC) AS RN
FROM PAYROLLYEAREND ) s
WHERE RN = 1 AND ID = '16443' AND PAYROLL_NUMBER ='7'
In the above example, the EVENT_SEQUENCE_NUMBER is populated with values from 0 to 12. Could vary per user and PAYROLL_NUMBER. The query above returns 48 rows. However, all I want are the rows where EVENT_SEQUENCE_NUMBER is equal to the highest, which is in the above example is 12. The result would be 29 rows. The where clause is not part of overall query. Just isolating on one ID.
