I need to group the query below by dda.LA and need to display all the columns listed in the select but almost none of them are aggregated. i don't know what the syntax to get around this is and i can not find a post that shows this syntax (most examples only have one table, two at tops).
Select dda.a,
dda.b,
dda.c,
dda.d,
dda.e,
dda.f,
dda.g,
dda.h,
dda.i,
dda.j,
dda.k,
dda.l,
dda.m,
dda.n,
dda.o,
dda.p,
dda.r,
dda.u,
dda.LA,
dd.aa,
coalesce(apn.apn,Pt.z) as abc,
coalesce(apn.v,Pt.y) as def,
'RFN' RowFocusIndicator ,
'SRI' SelectRowIndicator ,
'Y' Expanded ,
Convert(Int, Null) SortColumn
From dda (NoLock)
Inner Join dd (NoLock) On dda.d = dd.q and dda.e = dd.e
Left Outer Join apn (nolock) on dda.r = apn.r
Left Outer Join Pt (nolock) on dda.s = Pt.t
Where 1 = 1
And dda.u = (Select Min(c.w)
From c (NoLock)
Where c.x = dda.s)
Thanks!
Just add this to any column that you want to aggregate by:
AggregatedColumnName = Aggregation(fieldToAggregate) Over (Partition By dda.LA)
ex.
aCount = Count(dda.a) Over (Partition By dda.LA)

In my below T-SQL Query I need to use EFP_MessageCenter.MessageSender from my main SELECT in the SELECT in my LEFT OUTER JOIN as the value where I have placed <MessageSenderInitials>.
When I set (EFP_MessageCenter_1.MessageSender = EFP_MessageCenter.MessageSender) or (EFP_MessageCenter_1.MessageSender = MessageSenderInitials) I get the error The multi-part identifier "EFP_MessageCenter.MessageSender" could not be bound.
How can I get this to work?

I've made a slight refactor of your query and changed the outer join to an an outer apply
It's not going to be 100% working I'm sure but should allow you to tweak it and include the correlation you need to.
I suspect you could move the CountNonReadMessages to a count(*) in the apply and possibly remove the aggregation, but that's just a guess.
select Lower(mc.MessageSender) as MessageSenderInitials
, Max(s.FullName) as SenderFullName
, Max(s.ProfilePicture) as SenderProfilePicture
, Max(mr.UserID) as ReceiverID
, Max(mc.MessageTimestamp) as ChangeDate
, Count(s.Displayed) as CountNonReadMessages

join EFP_MessageCenter mc on mr.MessageID = mc.id
join EFP_EmploymentUser eu on mc.MessageSender = eu.Initials
outer apply (
select mr.Displayed
from EFP_MessageCenter mcx
join EFP_MessageCenter_Receiver mrx on mcx.id = mrx.MessageID
where mrx.Displayed = 0
and mrx.UserId=mr.UserId
and mcx.UserID = 65 /* this should probably be correlated */
and mcx.MessageSender = '<MessageSenderInitials>'
) s
where mr.UserID = 65 and mc.MessageType = 'SPECIFIC'
group by mc.MessageSender
order by ChangeDate desc

If I add new event_event or new product_product I'll get a new definition of row_number in my view, then the column ID of my view is not stable.
at least you can't use row_number as Id of the view,
If you insist to use row_number, you can use the Order By "creation DATE" by this way all new records will be as last lines in the view and this will not change the correspondency between ID (row_number) and other columns.
Hope that helps !
Very likely the execution plan of your query depends on the columns you select. Compare the execution plans!
Your id is generated using the row_number window function. Now window functions are executed before the ORDER BY clause, so the order will depend on the execution plan and hence on the columns you select.
Using row_number without an explicit ordering doesn't make any sense.
To fix that, don't use
row_number() OVER ()
but
row_number() OVER (ORDER BY e.id, pt.categ_id, p.id)
so that you have a reliable ordering.
In addition, you should omit the ORDER BY clause at the end.
This query was taken from a Rails application log...I'm trying to edit a massive postgresql statement I didn't write....If I don't add a distinct keyword after the SELECT, 2 duplicate rows appear for each braintree account. Why is this and is there another way to avoid having to use the distinct to avoid duplicates?
EDIT: I understand what distinct is supposed to do, the reason I'm asking is that it doesn't generate duplicates for other toy lines. By other toy lines, this query is building a "table" for a particular toy id (this specific example toys.id = 12). How do I figure out where the duplicate rows are being generated?

please help how can i write a query to have this result.
no idea how!!!!

how to join these 3 in one?
Grouping on Strasse etc. is not necessary and can be quite expensive. What about this approach:
SELECT K.*, ISNULL(Au.AnzahlAuftr,0) AS AnzahlAuftr, ISNULL(Au.AnzahlFahrt,0) AS AnzahlFahrt, ISNULL(Au.SumStrecke,0) AS SumStrecke
FROM Kunde K
LEFT OUTER JOIN
(SELECT A.Au_Kd_ID, COUNT(*) AS AnzahlAuftr, SUM(Fa.AnzahlFahrt1) AS AnzahlFahrt, SUM(Fa.SumStrecke2) AS SumStrecke
FROM Auftrag A LEFT OUTER JOIN
(SELECT F.F_Au_ID, COUNT(*) AS AnzahlFahrt1, SUM(Ts.SumStrecke1) AS SumStrecke2
FROM Fahrten F LEFT OUTER JOIN
(SELECT T.Ts_F_ID, SUM(T.Ts_Strecke) AS SumStrecke1
FROM Teilstrecke T
GROUP BY T.Ts_F_ID) AS Ts
ON Ts.Ts_F_ID = F.F_ID
GROUP BY F.F_Au_ID) AS Fa
ON Fa.F_Au_ID = A.Au_ID
GROUP BY A.Au_Kd_ID) AS Au
ON Au.Au_Kd_ID = K.Kd_ID

How to eliminate NULL fields in TSQL
I am using SSMS 2008 R2 and am developing a TSQL query. I want just 1 record / profile_name. Because some of these values are NULL, I am currently doing LEFT JOINS on most of the tables. But the problem with the LEFT JOINs is that now I get > 1 record for some profile_names!
But if I change this to INNER JOINs then some profile_names are excluded entirely because they have NULL values for these columns. How do I limit the query result to just one record / profile_name regardless of NULL values? And if there are non-NULL values then I want it to choose the record with non-NULL values. Here is initial query:
select distinct
gp.group_profile_id,
gp.profile_name,
gp.license_number,
gp.is_accepting,
case when gp.is_accepting = 1 then 'Yes'
when gp.is_accepting = 0 then 'No '
end as is_accepting_placement,
mo.profile_name as managing_office,
regions.[region_description] as region,
pv.vendor_name,
pv.id as vendor_id,
at.description as applicant_type,
dbo.GetGroupAddress(gp.group_profile_id, null, 0) as [Office Address],
gsv.status_description
from group_profile gp With (NoLock)
inner join group_profile_type gpt With (NoLock) on gp.group_profile_type_id = gpt.group_profile_type_id and gpt.type_code = 'FOSTERHOME' and gp.agency_id = #agency_id and gp.is_deleted = 0
inner join group_profile mo With (NoLock) on gp.managing_office_id = mo.group_profile_id
left outer join payor_vendor pv With (NoLock) on gp.payor_vendor_id = pv.payor_vendor_id
left outer join applicant_type at With (NoLock) on gp.applicant_type_id = at.applicant_type_id and at.is_foster_home = 1
inner join group_status_view gsv With (NoLock) on gp.group_profile_id = gsv.group_profile_id and gsv.status_value = 'OPEN' and gsv.effective_date =
(Select max(b.effective_date) from group_status_view b With (NoLock)
where gp.group_profile_id = b.group_profile_id)
left outer join regions With (NoLock) on isnull(mo.regions_id, gp.regions_id) = regions.regions_id
left join enrollment en on en.group_profile_id = gp.group_profile_id
join event_log el on el.event_log_id = en.event_log_id
left join people client on client.people_id = el.people_id
As you can see, the results of the above query is 1 row / profile_name:
group_profile_id profile_name license_number is_accepting is_accepting_placement managing_office region vendor_name vendor_id applicant_type Office Address status_description Cert Date2
But now watch what happens when I add in 2 LEFT JOINs and 1 additional column:
select distinct
gp.group_profile_id,
gp.profile_name,
gp.license_number,
gp.is_accepting,
case when gp.is_accepting = 1 then 'Yes'
when gp.is_accepting = 0 then 'No '
end as is_accepting_placement,
mo.profile_name as managing_office,
regions.[region_description] as region,
pv.vendor_name,
pv.id as vendor_id,
at.description as applicant_type,
dbo.GetGroupAddress(gp.group_profile_id, null, 0) as [Office Address],
gsv.status_description,
ri.[description] as race
from group_profile gp With (NoLock)
inner join group_profile_type gpt With (NoLock) on gp.group_profile_type_id = gpt.group_profile_type_id and gpt.type_code = 'FOSTERHOME' and gp.agency_id = #agency_id and gp.is_deleted = 0
inner join group_profile mo With (NoLock) on gp.managing_office_id = mo.group_profile_id
left outer join payor_vendor pv With (NoLock) on gp.payor_vendor_id = pv.payor_vendor_id
left outer join applicant_type at With (NoLock) on gp.applicant_type_id = at.applicant_type_id and at.is_foster_home = 1
inner join group_status_view gsv With (NoLock) on gp.group_profile_id = gsv.group_profile_id and gsv.status_value = 'OPEN' and gsv.effective_date =
(Select max(b.effective_date) from group_status_view b With (NoLock)
where gp.group_profile_id = b.group_profile_id)
left outer join regions With (NoLock) on isnull(mo.regions_id, gp.regions_id) = regions.regions_id
left join enrollment en on en.group_profile_id = gp.group_profile_id
join event_log el on el.event_log_id = en.event_log_id
left join people client on client.people_id = el.people_id
left join race With (NoLock) on el.people_id = race.people_id
left join race_info ri with (nolock) on ri.race_info_id = race.race_info_id
The above query results in all of the same profile_names, but some with NULL race values:
group_profile_id profile_name license_number is_accepting is_accepting_placement managing_office region vendor_name vendor_id applicant_type Office Address status_description Cert Date2 race
Unfortunately it complicates matters that I need to join in 2 additional tables for this one additional field value (race). If I simply change the last two LEFT JOINs above to INNER JOINs then I eliminate the NULL rows above. But I also eliminate some of the profile_names:
group_profile_id profile_name license_number is_accepting is_accepting_placement managing_office region vendor_name vendor_id applicant_type Office Address status_description Cert Date2 race
Hopefully I have provided all of the details that you need for this question.
Not the most elegant solution, but one that will work:
select [stuff]
from group_profile gp With (NoLock)
inner join group_profile_type gpt With (NoLock) on gp.group_profile_type_id = gpt.group_profile_type_id and gpt.type_code = 'FOSTERHOME' and gp.agency_id = #agency_id and gp.is_deleted = 0
inner join group_profile mo With (NoLock) on gp.managing_office_id = mo.group_profile_id
join payor_vendor pv on ISNULL(gp.payor_vendor_id, 'THISVALUEWILLNEVEROCCUR') = ISNULL(pv.payor_vendor_id, 'THISVALUEWILLNEVEROCCUR')
...etc...
Biggest issue with what I posted is that you'll be doing a whole lot of table scans.
