To Return Distinct Column Using INNER JOIN

Apr 23, 2008

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

SQL Server 2008 :: How To Return 1 Particular Column From Another Table In Join

Apr 25, 2015

I'm creating a sql stored procedure inside this proc it returns some information about the user, i.e location, logged in, last logged in, etc I need to join this on to the photos table and return the photo which has been set as the profile picture, if it hasn't been set then return the first top 1 if that makes sense?

The user has the option to upload photos so there might be no photos for a particular user, which I believe I can fix by using a left join

My photos table is constructed as follows:

CREATE TABLE [User].[User_Photos](
[Id] [bigint] IDENTITY(1,1) NOT NULL,
[UserId] [bigint] NOT NULL,
[PhotoId] [varchar](100) NOT NULL,
[IsProfilePic] [bit] NULL,

[Code] ....

Currently as it stands the proc runs but it doesn't return a particular user because they have uploaded a photo so I need to some how tweak the above to return null if a photo isn't present which is where I'm stuck.

Trying To Return Whole Records With Distinct Fields

Oct 17, 2006

Hi

I am trying to write a query that will return a full record with a particular distinct field (the rest of the record being the first such record that includes the distinct field).

For example, for the following:

Fruit Like? Colour
Apple Y Green
Orange N Orange
Banana Y Yellow
Grape Y Green
Grapefruit N Yellow

I would want to return (assuming Colour was the distinct field):

Fruit Like? Colour
Apple Y Green
Orange N Orange
Banana Y Yellow

How do I do this? I've tried using a join (of all different kinds) with a subquery that uses SELECT DISTINCT but this doesn't seem to work. I've tried GROUP BY but none of the aggregate functions seem to just take the first found field.

Thanks for any help you can offer.

Return Distinct Values From Stored Procedures

Aug 17, 2006

I need to somehow filter the results of my stored procedure to return the distinct "OrderNum" values. I'm using SQL database and I'm look for a way to alter the results from the stored procedure. My stored procedure rptOpenOrderLines currently returns all invoices (items under a OrderNum). I want to somehow filter those results to return one and only one of those "OrderNum" variables from the invoices. The tricky part is that I need to somehow find a way to do this without going into my database and directly altering the SQL stored procedure. I would be happy for any recommendations/ideas. Thanks!

Select Distinct One Some Fields, But Return All Feilds

Jul 23, 2005

I was curious...Is there a way to select distinct on a combination of some fields andthe for each record returned also get the other fields of anarbitrarily chosen record matching the fields in the distinct record.For example, if I have a select distinct on say three fields:SELECT DISTINCT Code1, Code2, Code3but the table also has other fields, maybe Foo1 and Foo2, and I wantFoo1 and Foo2 to also be displayed. Since there may be multiplerecords that match a particular Code1, Code2, Code3, then I just wantone of those to be arbitrarily chosen.

SELECT DISTINCT To Return Only The YEARS In A Date Field?

Mar 22, 2006

I have a table in my MS SQL 2000 database called News which has a field caled NewsDate. This is a standard Date field which stores the info in this format: 3/1/2001.

I want to create a query that returns one row for each year that there is a story.

For example, if I had this data...
3/1/2001, 6/27/2003. 9/17/2003, 1/1/2006, 4/5/2006

the query would return this result:

2001
2003
2006

This is the query I've started with:

SELECT DISTINCT NewsDate FROM News ORDER BY NewsDate DESC

What modifier can I apply to the NewsDate field to extract JUST the year from the table? If this were ASP I would try something like Year(Date), but, of course, I can't do that here.

Is this even possible? I've been looking up date functions, but haven't found anything that will work in a select statement. ANY and ALL advice will be greatly appreciated.

Right Outer Join And Distinct

Dec 15, 2014

I have a view which joins 2 tables together in a left outer join.

Now, the left outer join table (lets call this SalesData) may or may not have records. As months and years go by, records will be inserted or updated.

I am trying to find a query which will do the following:

Bring back all records where the branch matches an input value and also:

- bring back NULL records for the YR and MO column
- bring back values which match the input params for YR and MO column.

this works as expected:

quote:
SELECT wmtecp.*
FROM v_stores wmtecp
RIGHT OUTER JOIN v_Stores roj ON wmtecp.ID = roj.ID
WHERE wmtecp.TM = @p1 AND 1=1 AND roj.YR IS NULL AND roj.MO IS NULL OR wmtecp.MO = 11 AND wmtecp.YR = 2014

This is right outer joining the view to itself and prefer it this way.

Here is the thing: I want to bring back only distinct records (distinct by store ID I guess).

We are bringing back result set which contains NULL and NON null values but for both result sets the same storeID is returned, I do not want this but to only bring back the same record once either WITH values or WITHOUT values.

Not Getting Distinct Results With Inner Join

Mar 5, 2007

Hello, 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.

SELECT DISTINCT With JOIN

Jul 20, 2005

Hi everyoneHave a problem I would areally appreciate help with.I have 3 tables in a standard format for a Bookshop, egProductsCategoriesCategories_Productsthe latter allowing me to have products in multiple categories.Everthing works well except for one annoying little thing.When an individual product (which is in more than one topcategory) is addedto the Shopping Cart it displays twice, because in my select statement Ihave the Category listed. I realise I could remove the TopCategory from thestatement and that makes my DISTINCT work as I wanted, but Id prefer to havethe TopCategory as it saves me later having to another SQL query (Im alreadydoing one to allow me not to list category in the Statement .... but If Ican overcome this one ... then I can remove this as well).Here is my table structure (the necessary bits)productsidProduct int....categoriesidcategory intidParentCategory inttopcategory int...categories_productsidCatProd intidProduct intidCategoryWhen I run a query such asSELECT DISTINCT a.idProduct, a.description,a.descriptionLong,a.listPrice,a.price,a.smallImageUrl,a.stock, a.fileName,a.noShipCharge,c.topcategoryFROM products a, categories_products b, categories cWHERE active = -1 AND homePage = -1AND a.idProduct = b.idProductAND c.idcategory=b.idcategoryAND prodType = 1 ORDER BY a.idProduct DESCThis will return all products as expected, as well as any products which arein more than one TopCategory.Any ideas how to overcome this would be greatly appreciated.CheersCraig

Select DISTINCT In LEFT JOIN

Feb 14, 2008

Hi again,
I have this SQL (part of a stored procedure) where I do LEFT JOIN. SELECT callingPartyNumber, AlertingName, originalCalledPartyNumber, finalCalledPartyNumber,
dateTimeConnect,
dateTimeDisconnect,
CONVERT(char(8), DATEADD(second, duration, '0:00:00'), 108) AS duration,
clientMatterCode

FROM CDR1.dbo.CallDetailRecord t1
LEFT JOIN CDR2.dbo.NumPlan t2 ON t1.callingPartyNumber=t2.DNorPattern

WHERE
(t1.callingPartyNumber LIKE ISNULL(@callingPartyNumber, t1.callingPartyNumber) + '%') AND
(t1.originalCalledPartyNumber LIKE ISNULL(@originalCalledPartyNumber, t1.originalCalledPartyNumber) + '%') AND
(t1.finalCalledPartyNumber LIKE ISNULL(@finalCalledPartyNumber, t1.finalCalledPartyNumber) + '%') AND
(t1.clientMatterCode LIKE ISNULL(@clientMatterCode, t1.clientMatterCode) + '%') AND
(@callerName is NULL OR t2.AlertingName LIKE '%' + @callerName + '%') AND
(t1.duration >= @theDuration) AND
((t1.datetimeConnect) >= ISNULL(convert(bigint,
datediff(ss, '01-01-1970 00:00:00', @dateTimeConnect)), t1.datetimeConnect)) AND
((t1.dateTimeDisconnect) <= ISNULL(convert(bigint,
datediff(ss, '01-01-1970 00:00:00', @dateTimeDisconnect)), t1.dateTimeDisconnect))
The problem is that if the t2 has more than one entry for the same DNorPattern, it pulls the record more than once. So say t1 has a callingPartyNumber = 1000. t2 has two records for this number. It will pull it more than once. How do I get the Unique value.
What I am trying to get is the AlertingName (name of the caller) field value from t2 based on DNorPattern (which is the phone number).
If this is not clear, please let me know.
Thanks,
Bullpit

This query means all record from second table and matching record from first table. Now my question is that on 24 Feb 2015 I have duplicate names in second table and I want distinct names from second table and then its matching values from first table. Now my query is showing all duplicate values from second table and its matching record from first table.

Selecting Distinct Top 3 Rows From Database Using Join

Jun 25, 2007

Hi guys,

Just trying to select a set of Articles from a SQL Server Database. The Articles all have a Category ID which is stored in another table (as an Article could be in more than one Category). I want to select the Top 3 Articles in a Category. At the moment I have as my SQL;

"SELECT TOP 3 f.ArticleID, f.Heading, f.Summary, f.WrittenDate, f.ArticleURL FROM feedTable f LEFT JOIN Categories c ON f.ArticleID = c.ArticleID WHERE c.CategoryID=" + CategoryID + " AND c.ArticleID<>" + id + " ORDER BY c.CategoryID"

Which seems to work to an extent in that I do get three articles in the same Category appearing. However, there are sometimes duplicates appearing, so I need to incorporate a DISTINCT clause to the above. I'm not sure where to put this in though. Any ideas?

Thanks.

I need that in order to effectively page through my records, but it also makes thatI cant make a distinct selection as each RowNum is unique....:SIn case the user would practice 2 sports, the query would return 2 rows...if I place a distinct in front of the username as such:select distinct username fromThe query would return each user only once...BUTBUTBUT: my startrowindex and maximumrows apply to the results that can be found in the MemberInfo selection..so lets say my startrowindex would be 0 and maximumrow 5if my 1st query (without distinct) was to return:johnjohnjohnjohnmikemikerobmy 2nd query (with distinct) would return:johnmikewhereas I want it to return:johnmikerobWhat can I do?

Getting Duplicates With Select Distinct (full Outer Join)

Aug 3, 2006

I am writing a script to create a audit trigger on any table. I am getting duplicate rows inserted into my audit table, only for the primary key columns. Anybody see why?

Right now I am debugging an Insert, so I think you can ignore the "U" update part of the Where clause.

....starts with other code to determine columns and primary key fields for selected table....

--get number of columns
select
@rowId = min(RowId),
@MaxRowId = max(RowId)
from #tblFieldNames

-- Loop through fields and build Sql string
while @RowId <= @MaxRowId
BEGIN
SELECT @fieldname = colName FROM #tblFieldNames WHERE RowId = @RowId

SELECT @sql = 'insert tblAuditAdmin (TableAltered, [Action], FieldName, OldValue, NewValue, UpdateDate, UpdateNumber, UserName)'
SELECT @sql = @sql + ' select distinct''' + @TableName + ''''
SELECT @sql = @sql + ',''' + @TriggerType + ''''
SELECT @sql = @sql + ',''' + @fieldname + ''''
SELECT @sql = @sql + ',convert(varchar(1000),d.' + @fieldname + ')'
SELECT @sql = @sql + ',convert(varchar(1000),i.' + @fieldname + ')'
SELECT @sql = @sql + ',''' + @UpdateDate + ''''
SELECT @sql = @sql + ', 1'
SELECT @sql = @sql + ',''' + @UserName + ''''
SELECT @sql = @sql + ' FROM #ins i FULL OUTER JOIN #del d'
SELECT @sql = @sql + @pkJoinClause
SELECT @sql = @sql + ' WHERE (''' + @TriggerType + ''' = ''I'')'
SELECT @sql = @sql + ' OR (''' + @TriggerType + ''' = ''D'')'
SELECT @sql = @sql + ' OR (''' + @TriggerType + ''' = ''U'' AND '
SELECT @sql = @sql + '((i.' + @fieldname + ' <> d.' + @fieldname + ')'
SELECT @sql = @sql + ' OR (''' + @fieldname + ''' in (Select colName from #primaryKeyFields))'
SELECT @sql = @sql + ' OR (i.' + @fieldname + ' IS NULL AND d.' + @fieldname + ' is NOT null)'

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.

Help With A Join That Needs To Return Unique Records

Apr 28, 2008

Hi All,

I need a bit of help with a join. I have 2 tables :

TradeSummary
has fields : SymbolID, CurrentPrice, TotalValue

Trades
has fields : SymbolID, TradeID, ExecutionTime, TradeValue

TradeSummary has one entry for each SymbolID, while Trades contains one or more entries per SymbolID

and what I want to retreive is :

For every item in TradeSummary get CurrentPrice, TotalValue from TradeSummary
and also get TradeValue from Trades for the record for max(ExecutionTime)
tables are joined on TradeSummary.SymbolID = Trades.SymbolID

Every attempt of mine so far returns multiple rows for each SymbolID - I want only one row per SymbolID

If we say

SELECT distinct siteid ,ts1, ts2, ts3, ts4, ts5, ts6, ts7, ts8

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 ?

Distinct On Single Column?

Aug 30, 2007

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:

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.

SELECT DISTINCT On One Column

Oct 19, 2006

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!

Return NULL Values In SELECT Statement With INNER JOIN ?

May 16, 2005

If I try to run the code below, and even one of the values in the INNER
JOIN statements is NULL, the DataReader ends up with zero rows.
What I need is to see the results even if one or more of INNER JOIN
statements has a NULL value. For example, if I want info on
asset# 2104, and there's no value in the DriverID field, I need the
rest of the data to display and just have the lblDriverName by
blank. Is that possible?

<code>
    Sub BindSearchGrid()
        Dim searchUnitID As String
        Dim searchQuery As String
        searchUnitID = tbSearchUnitID.Text
        lblIDNum.Text = searchUnitID
        searchQuery = "SELECT * FROM Assets " & _
        "INNER JOIN Condition ON Condition.ConditionID = Assets.ConditionID " & _
        "INNER JOIN Drivers ON Drivers.DriverID = Assets.DriverID " & _
        "INNER JOIN Departments ON Departments.DepartmentID = Assets.DepartmentID " & _
        "INNER JOIN AssetCategories
ON AssetCategories.AssetCategoryID = Assets.AssetCategoryID " & _
        "INNER JOIN Store ON
Store.[Store ID] = Assets.StoreID WHERE RTRIM(Assets.[Unit ID]) = '"
& searchUnitID & "'"
