I am attempting to run the following select statement joining multiple tables but in the end result I would like only Distinct/Unique values to be returned in the invlod.lodnum column.
[select pw.schbat, adrmst.adrnam, adrmst.adrln1, adrmst.adrcty, adrmst.adrstc, adrmst.adrpsz,
invlod.lodnum,
shipment.host_ext_id, shipment_line.ordnum, car_move.car_move_id
from aremst join locmst
on (aremst.arecod = locmst.arecod)
and (aremst.wh_id = locmst.wh_id)
[Code] .....
12.) Now you have two different tables - each with two columns.Table #1Single Column2 rows with a value equal to 1 and 2Table #2Single column2 rows with a value equal to 2 and 4Construct a statement returning in a single column all the valuescontained, but not the common values.This is another question that I got in an interview, I missedit.......Thanks,Tim

I have a SQL Query issue you can find in SQL Fiddle
SQL FIDDLE for Demo
My query was like this
For Insert
Insert into Employee values('aa', 'T', 'qqq')
Insert into Employee values('aa' , 'F' , 'qqq')
Insert into Employee values('bb', 'F' , 'eee')
Insert into Employee values('cc' , 'T' , 'rrr')
Insert into Employee values('cc' , 'pp' , 'aaa')
Insert into Employee values('cc' , 'Zz' , 'bab')
Insert into Employee values('cc' , 'ZZ' , 'bac')
For select
select col1,MAX(col2) as Col2,Max(Col3) as Col3
from Employee
group by Col1
I supposed to get last row as
cc Zz bab
Instead I am getting
cc Zz rrr
which is wrong
Ok, so I need to count the Distinct records from column 1 in which there is not a true value in any of the records for that distinct column 1 number. Here is a short example of my records:dbo_dbWafer_Slicing

So, how many Distinct SawRunNumbers had no passing wafers? In trying to do this I've come up with:"SELECT COUNT(DISTINCT SawRunNumber) AS BouleCount FROM dbWafer_Slicing WHERE (SawDate >= @MinDate) AND (SawDate <= @MaxDate) AND (Pass = 1) HAVING (COUNT(DISTINCT WaferID) > 0)" but that doenst work. It still counts records where pass = 0 for distinct SawRunNumbers even if one record within that SawRunNumber is passing. From the above sample data I should get a result of 1 not 2 or 3. Can I do this with this set of data? I'm using SQL Server 2005 EE.Thanks for your help.
Here's an example of what I am trying to do...
Table1: id, name, title,...
Table2: id, regionID, region,...
t1 has a 1 to many relationship to t2
(no keys on t2)
SELECT DISTINCT t1.name, t1.title
FROM table1 t1 INNER JOIN
table2 t2 ON t1.id = t2.id
That works fine... Now, I want to include a third table...
Table3: regionID , RegionName, location,...
SELECT DISTINCT t1.name, t1.title, t3.RegionName
FROM table1 t1 INNER JOIN
table2 t2 ON t1.id = t2.id INNER JOIN
table3 t3 ON t2.regionID = t3.regionID
A sample result would be....
Bill, Owner, England
Jim, Owner, France
Jim, Owner, Spain
However, I would like to only list the individuals (ie. Jim, Owner) one time! Only the first 2 fields (name, title) need to be distinct. How do I reference the third table without including it in the DISTINCT keyword?
Any guidance would be appreciated.
Thanks,
Andrew
We have SharePoint list which has, say, two columns. Column A and Column B.
Column A can have three values - red, blue & green.
Column B can have four values - pen, marker, pencil & highlighter.
A typical view of list can be:
Column A - Column B
red - pen
red - pencil
red - highlighter
blue - marker
blue - pencil
green - pen
green - highlighter
red - pen
blue - pencil
blue - highlighter
blue - pencil
We are looking to create a report from SharePoint List using SSRS which has following view:
red blue green
pen 2 0 1
marker 0 1 0
pencil 1 3 0
highlighter 1 1 1

I am using this below query to generate this below result set. I want to display only one record as blank, it should not be duplicate records.
SELECT [MDMTerminalID], ISNULL([TerminalAlias], 'BLANK') , [RegionID] FROM [dbo].[Terminal]
Union
select -1,'All', (select top 1 areaid from area where name = 'Other')
I have 3 tables:
News:
bigint NewId
nvarchar NewTitle

nvarchar NewBrief

Category:

nvarchar CatName
--------------------------
NewsRelCategory:
bigint Id
int CategoryIdFk
bigint NewsIdFk
--------------------------
I want to select NewId, NewDate and Distinct NewTitle
I tried this but NewTitle doesn't distinct:
SELECT
FROM dbo.Category INNER JOIN
NewsRelCategory ON dbo.Category.CatId = NewsRelCategory.NrcCategoryIdFk INNER JOIN
dbo.News ON NewsRelCategory.NrcNewsIdFk = dbo.News.NewId
best way to go about this. My query works great and displays the information I require.
EG all demographic for ED, IP & OP. However if a patient has a record in each of the tables then I get the same info multiple times.
What I'm trying to do is a Select Distint against the entire query (below).
eg Select Distinct * from all below.
DECLARE @StartDate datetime = '01 oct 2015';
DECLARE @EndDate datetime = '30 OCT 2015';

We have a query in which there are 20,000 rows and 90 distinct ID's
If we say
SELECT distinct siteid ,ts1, ts2, ts3, ts4, ts5, ts6, ts7, ts8
from #TEMPX
we get the 90 distinct values, but if we say
SELECT distinct siteid ,ts1, ts2, ts3, ts4, ts5, ts6, ts7, ts8, ts1avg, ts2avg, ts3avg, ts4avg, ts5avg, ts6avg, ts7avg, ts8avg from #TEMPX
TS1 contains 90 distinct values, whily ts1avg has 2,000 disitinct rows
Is there a way to get Distinct to work against only one column, i.e. SiteID ?
Hi,
This is a query that joins a vouple of tables to display all the products purchased by a group of customers and the price they paid for it.
SELECT DISTINCT (p.code),p.descript_1 + ' ' + p.descript_2 + ' ' + p.descript_3 as description,sol.p_sales as price,sol.q_ordered as quantity,(sol.p_sales * sol.q_ordered) as total,so.date_in as dateFROM EfasLive..debtor AS d
INNER JOIN Informatica..so AS so ON so.deb_code = d.code AND so.co_code = d.co_code
INNER JOIN Informatica..so_line AS sol ON sol.code = so.code AND sol.co_code = so.co_code AND sol.acc_year = so.acc_year AND sol.efas = so.efas
INNER JOIN EfasLive..part AS p ON p.code = sol.part
WHERE d.[grp{003}] = 'GROUP' AND p.co_code = 1 AND p.code NOT LIKE '&%' AND so.date_in > DATEADD(m,-3,GETDATE()) AND sol.q_ordered > 0
ORDER BY (p.code), datum DESC
The problem with this is that it returns multiple lines for every product (p.code). Like so:
code description price quantity total date

I'd like there to be only 1 line for every different code with it's description. The idea is that the other rows are dropped and that only the first one remains. The one with the most recent purchase. I tried with GROUP BY but that's probably wrong since you'd have to add all the other columns as well and you end up with the same one. And even with adding a HAVING at the end I can't see how this could be solved
edit: There aren't any actual relationships in the tables (it's ancient you see ...) I'm using SQL 2005 though.
I know this is a popular problem, but i haven't found an answer to my situation.
I have a table (myTable) with three Columns (Column1, Column2, Column3). Column1 entries are unique (with unique identifier), Column2 entries are not unique.
I want to do a SELECT DISTINCT on myTable so that Column2 is unique and i get all the other columns. I thought something like this would work
SELECT DISTINCT Column2 as Col2, newid() as Col1, Column3 as Col4
-- I am getting uniqueidentifier for each row as well
This doesn't seem to work however. I still get all the rows because Col1 is unique.
since i am using aliases, the usual syntax doesn't work either.
any help would be greatly appreciated!
Hello everybody,
have following problem:
I need info from 2 Tables. from the Table 2 I just need 1 column. When i ask for this column the output I get is data repeating themselve many times.
Distinct, should give me unique data, but is doesnt....
the code:
SELECT DISTINCT FSenddate, FSupplyIDName, FSupplyerNumber,FBillNo,FSourceBillNo,FItemName,FItemModel,
FAuxQty,FAuxTaxPrice,FHeadSelfP0237
FROM vwICBill_26
WHERE FSenddate BETWEEN DATEADD(dd,-14,GETDATE()) AND GETDATE()
This code just works in Table1 (vwICBill_26)
but with table 2 (vwICBill_1)
SELECT DISTINCT vwICBill_26.FSenddate,vwICBill_26.FSupplyIDName,
vwICBill_26.FSupplyerNumber,vwICBill_26.FBillNo,
vwICBill_26.FSourceBillNo,vwICBill_26.FItemName,
vwICBill_26.FItemModel,vwICBill_26.FAuxQty,
vwICBill_26.FAuxTaxPrice,vwICBill_26.FHeadSelfP0237,
vwICBill_1.FDate,vwICBill_1.FContractBillNo
FROM vwICBill_26,vwICBill_1
WHERE vwICBill_26.FSenddate BETWEEN DATEADD(dd,-14,GETDATE()) AND GETDATE()
AND vwICBill_1.FContractBillNo=vwICBill_26.FSourceBillNo
The last sentence is the problem
I want that it shows me the data that is not equal.
As soon as I implement the not equal it shows me the massive repeating data.
I mean even without the last sentence I get this data output.
All together, I want a clear database output without data repeating.
Any ideas how it may work without DISTINCT?
I think this problem is a typical amateure problem, but I would apreciate help!
I need to get all distinct values from 10 different tables that exist in the field [favoritesport] And each table holds close to 50K records so I am looking at 500,000 records to get distinct values for. Would the fastest, less intrusive way of achieving this be to just create a UNION ALL so run
Select Distinct([favoritesport]) from table1
Union
Select Distinct([favoritesport]) from table2
Union
Select Distinct([favoritesport]) from table3
etc etc etc
T1
-------
a1
a2
datetime
a4
a5
.....
i need distinct max between a1&a2 which i can get no problem but i cant get that unique datetime that correspond to a1&a2 in 1 query because this is will a subquery in a big query. Creating another temp table etc is not an option for me. for every specific a1 there is many entries of a2 + timedate etc.
create table abc_test (
id int
,runs int
,date1 datetime
[code]....
I can either get distinct ID + latest date or ID + largest #ofRuns, both will do but also need the third column.
The below TSQL query takes about 19 minutes to run
SELECT count(distinct SessionID) ) FROM SessionTracker
Sessionid is a varchar(138)
Through SQL profiler - I notice implicit conversion taking place when running distinct option.
Select count(sessionid) from sessiontracker
- runs in milliseconds.
Hello all,
I am using INNER JOIN to connect 2 tables together but I wish it to return distinct columns instead of repeating itself !
eg.
Current output would be:
UserID Name UserID OrderID
1 John 1 5
2 Bob 2 6
I want it to be:
UserID Name OrderID
1 John 5
2 Bob 6
I need to use SELECT * as there are many many columns and wish to save time :)
Cheers,
James
Hi guys, I'm hoping there's someone out there with more sql knowledge and experience than me. I'll try to explain everything.
I'm trying to create a select statement but i'm not gettting the required results mainly because i think its a very complicated select.
Here is the scenario.
The table has 12 columns
ProductID Colour MD01 MD02 MD03 MD04 MD05 MD06 MD07 MD08 MD09 MD010
The ProductID is naturally the unique key.
There is always a colour value. But there is not always a value in the MD columns. For example one Product may have values in MD01 MD02 MD03 MD04 MD05 whilst another has values in all MD columns.
My problem is thatI am trying to create a results list based upon selecting distinct values from the colour and md columns
In otherwords i can't have more than only one instance of a word appearing in the recordset list
I'm really struggling with this because there are only 6 colours so if i set distinct purely on 6 colours i only get back 6 rows.
When I try to set disctinct across all the MD columns it seems to ignore it and lists results for example in the table
ProductID Colour MD01 MD02 MD03 MD04 MD05 MD06 MD07 MD08 MD09 MD010
1 red car bike
2 blue bike car train
my select lists results as
red
car
bike
blue
bike
car
train
and it is as if it only carries out the distinct command across the row not across all columns for all rows if you see what i mean?
I need to be able to list all data from all rows that have values in the MD columns and colour column but not list the values more than once and not list "empty" (NULL) columns. Does this make sense?
This is the select statement i wrote.
Select DISTINCT md00, md01, md02, md03, md04, md05, md06, md07, md08, md09, md10, colour FROM TEMPLATES WHERE md00 IS NOT NULL or md01 IS NOT NULL or md02 IS NOT NULL or md03 IS NOT NULL or md04 IS NOT NULL or md05 IS NOT NULL or md06 IS NOT NULL or md07 IS NOT NULL or md08 IS NOT NULL or md09 IS NOT NULL or md10 IS NOT NULL
But it returns empty columns and it returns every instance of the same word so in other words the distinct command doesn't seem to be working at all?
I don't know if this is because of my asp code I am trying to list results with the rescordset?
<%
While ((Repeat1__numRows <> 0) AND (NOT template_rs.EOF))
%>
<%=(template_rs.Fields.Item("md01").Value)%>
<%=(template_rs.Fields.Item("md02").Value)%>
<%=(template_rs.Fields.Item("md03").Value)%>
<%=(template_rs.Fields.Item("md04").Value)%>
<%=(template_rs.Fields.Item("md05").Value)%>
<%=(template_rs.Fields.Item("md06").Value)%>
<%=(template_rs.Fields.Item("md07").Value)%>
<%=(template_rs.Fields.Item("md08").Value)%>
<%=(template_rs.Fields.Item("md09").Value)%>
<%=(template_rs.Fields.Item("md10").Value)%>
<%=(template_rs.Fields.Item("colour").Value)%>
<%
Repeat1__index=Repeat1__index+1
Repeat1__numRows=Repeat1__numRows-1
template_rs.MoveNext()
Wend
%>
I have one more problem. How can I also in addition to being able to list all distinct results list only results for a specific letter
for example
Select DISTINCT md00, md01, md02, md03, md04, md05, md06, md07, md08, md09, md10, colour FROM TEMPLATES WHERE md00 IS NOT NULL or md01 IS NOT NULL or md02 IS NOT NULL or md03 IS NOT NULL or md04 IS NOT NULL or md05 IS NOT NULL or md06 IS NOT NULL or md07 IS NOT NULL or md08 IS NOT NULL or md09 IS NOT NULL or md10 IS NOT NULL WHERE FIRST LETTER ='A'?
I am so far out of my depth here guys I am hoping that someone who has real knowledge of SQL can help me with this statement. I've been pulling my hair out for days now and getting just more and more frustrated listing the same results :(

I have a table of users and date when they logged on to a system. I am trying to count how many distinct users logged on for each day of the week. The SQL below works when there's at least a user for each day. But when there is no user for a particular day such as Sunday, I still want it to return "SUN
0 "
I learned that you can use GROUP BY ALL and it works but the "ALL" is deprecated beyond SQL 2005.
------------------------------------
SELECT UPPER(LEFT(DATENAME(dw, StartTime), 3)) AS DayOfWeek,
COUNT(DISTINCT UserID) AS NumberOfUser
FROM testUserLoginDuration
WHERE Archived = 0
GROUP BY UPPER(LEFT(DATENAME(dw, StartTime), 3))
ORDER BY
CASE WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'MON' THEN 1
WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'TUE' THEN 2
WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'WED' THEN 3
WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'THU' THEN 4
WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'FRI' THEN 5
WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'SAT' THEN 6
WHEN UPPER(LEFT(DATENAME(dw, StartTime), 3)) = 'SUN' THEN 7
END
--------------
returns
MON 6

Okay, I've been working on this for a couple of hours with no success. I'm trying to find the number of telephone numbers that are associated with multiple students at different school sites. I've created a temp table that lists all phone numbers that are associated with more than one student. I'm now trying to query that table and count the number of telephone numbers that are associated with more than one site. Essentially, I'm looking for parent/guardians that have students at different sites.
Here's an example of what I'm hoping to accomplish:
*In this example, I'm just trying to get a count of the different/distinct school sites associated with each number. If I can, at the same time, limit it to a count of > 1 (essentially excluding parents with students at the same site), even better :)

On my company site, I have created a database that is for the purpose of tracking google adwords, as well as pages that the user visits. For instance, if you were to search for "guitars" and then click our ad, an entry is created in the database like thisKeyword: SessionGUID: PageVisited: VisitedDateTime:Guitars lkjfeilfjskdlfjsije ~ViewCategory.aspx?Cat=Guitars,KW=Guitars 12/01/2000 12:00amGuitars lkjfeilfjskdlfjsije ~ViewProduct.aspx?ProductID=1253&SubProductID=3 12/01/2000 12:03amGuitars lkjfeilfjskdlfjsije ~Search.aspx?Q=BC%20%Rich 12/01/2000 12:05am Pretty much, in our administrative area, I want to be able to have a table that would generate these results: Keyword Total HitsGuitars 3So im guessing that obviously I would need to do a select distinct for the Keyword column, but how do I also have a column showing a count of the records?

I'm trying to create a view in SQL Server to display only one copy of all records in a table, where some of the records are exact matches to other records (except for an ID autoincrement field)
I have the following code that displays distinct titles:
sql Code:
Original
- sql Code
SELECT DISTINCT DocTitle
FROM dbo.TBL_TABLE_NAME
SELECT DISTINCT DocTitleFROM dbo.TBL_TABLE_NAME
But when i use this code (adding one field to query), it displays all the duplicate records also, which I do not want:
sql Code:
Original
- sql Code
SELECT DISTINCT DocTitle, ID
FROM dbo.TBL_TABLE_NAME
SELECT DISTINCT DocTitle, IDFROM dbo.TBL_TABLE_NAME
I want to get the distinct results for DocTitle, with 5 other columns added to the query so they can be displayed in a web page list.
The query I want is something like this, but I can not get it to work:
sql Code:
Original
- sql Code
SELECT DISTINCT DocTitle, ID, FirstName, LastName, Company, DocDescription, DocFile
FROM dbo.TBL_TABLE_NAME
ORDER BY DocTitle
SELECT DISTINCT DocTitle, ID, FirstName, LastName, Company, DocDescription, DocFileFROM dbo.TBL_TABLE_NAMEORDER BY DocTitle
I know this query works from an MS Access DB, but I need it to work from SQL Server.
I am using SQL Server 2000
Any help is greatly appreciated.

Distinct name that match both subjects (math, science) from classname in level 2 only. Not sure where to even start. Example table below:
name subject level
bob math 2
hank math 1
joe science 2
bob science 2

Been trying to come up with a query to filter-down my sample set intodistinct records. For instance, lets say column1 is a sample set,column2 is the parameter, and column3 is a name and column4 is a type(lets also say there is a fifth column (id) that is an id). What Ineed is one record per type per sample only if type is given, if not,then return that record as well.I've used a subquery to get as close to the desired query is aspossible:select * from table1where id in (select min(id) from table1where column1="A"group by column1, column2)Here's an example of all data for sample "A":1 2 3 4----------A 1 X PA 1 Y PA 1 Z PA 2 WA 3 WA 4 T PA 5 U PA 6 V PA 7 TA 7 UA 7 VI want output :1 2 3-------A 1 X PA 2 WA 3 WA 4 T PA 5 U PA 6 V PA 7 TA 7 UA 7 VExcept the above query will exclude the last two records becausecolumn3 is not 'grouped by'.Basically I need to reduce any 'range' of records per sample (columna) where column4 is not null (ie = 'P'), to only one record andkeeping all others. Thanks in advance:-B

This query demonstrates a problem I have run across:
USE AdventureWorks
GO
-- This query works fine.
SELECT DISTINCT FirstName AS Name1 FROM Person.Contact ORDER BY FirstName
GO
-- This query also works fine.
SELECT ISNULL(FirstName, '') AS Name1 FROM Person.Contact ORDER BY FirstName
GO
-- This query returns error 145
SELECT DISTINCT ISNULL(FirstName, '') AS Name1 FROM Person.Contact ORDER BY FirstName
GO
The last query returns the error "ORDER BY items must appear in the select list if SELECT DISTINCT is specified".
It will work if I change ORDER BY to use "Name1" instead of "FirstName", but in the situation I have at hand, the query is generated by third-party software and I don't have the ability to change it.
Can anyone explain why what's going on here? Oddly, this same query will work if I run it against SQL Server 2000.
