You don't need group by in your query. It is used when there is an aggregated function like sum, max etc. in select statement. You also missed mentioning t-a before inner join in your query. I have included that in my query.
Also, Left outer join is nothing but Left join itself. Therefore, I changed that also in the query
Try this:-
SELECT distinct
t-a.col, t-b.col, s-b.col
FROM t-a
INNER JOIN t-1 ON t-1.id = t-a.id
LEFT JOIN t-b on t-a.id = t-b.id

LEFT JOIN s-b on s-a.id=s-b.id;

I'm trying to add a conditional SELECT column in a query and I'm having trouble writing it out:
SELECT v.GLTypeID,
v.something,
v.somethignElse,
CASE WHEN (SELECT TOP 1 Value FROM InterfaceParam WHERE InterfaceId = 0 AND Descr = 'gf') = 1 THEN a.CreditID ELSE NULL END AS CreditMemoID
FROM vGLDetails2 v
....
LEFT OUTER JOIN AssociationFund f
ON v.FundID = f.FundID
LEFT JOIN dbo.APLedger a ON v.RelID = a.APLedgerID AND v.RelTypeID IN (39, 40)
....
ORDER BY v.Code;
The query above works, however if the CASE statement is still returning an additional column regardless of the result of the subquery. How can I remove it if the subquery doesn't return a row?
How can I do this?
Change the location of AS. For example:
SELECT v.GLTypeID,
v.something,
v.somethignElse,
CASE WHEN (
SELECT TOP 1 Value
FROM InterfaceParam
WHERE InterfaceId = 0 AND Descr = 'creditMemo') = 1
THEN a.CreditID -- AS is not valid here
END AS CreditMemoID -- AS is valid here
FROM vGLDetails2 v
....
LEFT OUTER JOIN AssociationFund f
ON v.FundID = f.FundID
LEFT JOIN dbo.APLedger a ON v.RelID = a.APLedgerID AND v.RelTypeID IN (39, 40)
....
ORDER BY v.Code;
Note: I removed ELSE NULL since this is the default behavior of CASE.

And the output is how we need it, however, we need to be able to search it and we cannot get that working. So how does one reference the column 'Name' that the Stuff function creates in the WHERE clause of the query?
We need to do a search within the HAVING OR WHERE clause for a value within the 'divList' column if possible. Such as divList IN ('OHCM').
Anytime I reference 'divList', I get the error:
Invalid column name 'divList'.
This would filter the results to records 1 and 2.
I hope that better explains it.
You don't want the string. Use more basic logic instead:
having sum(case when division_name = 'ccc' then 1 else 0 end) > 0
How is your temp table associated with the view. You need to join your temp table with the nominations view.

OK, I've looked this up and tried a number of solutions, but can't get it to work. I'm a bit of a novice. Here's my original query - how can I get it to return 0 for an account when there are no results in the student table?
SELECT a.NAME
,count(s.student_sid)
FROM account a
JOIN inst i ON a.inst_sid = i.root_inst_sid
JOIN inst_year iy ON i.inst_sid = iy.inst_sid
JOIN student s ON iy.inst_year_sid = s.inst_year_sid
WHERE s.demo = 0
AND s.STATE = 1
AND i.STATE = 1
AND iy.year_sid = 16
AND a.account_sid IN (
20187987
,20188576
,20188755
,52317128
,20189249
)
GROUP BY a.NAME;
Use an outer join, moving the condition on that table into the join:
select a.name, count(s.student_sid)
from account a
join inst i on a.inst_sid = i.root_inst_sid
join inst_year iy on i.inst_sid = iy.inst_sid
left join student s on iy.inst_year_sid = s.inst_year_sid
and s.demo = 0
and s.state = 1
where i.state = 1
and iy.year_sid = 16
and a.account_sid in (20187987, 20188576, 20188755, 52317128, 20189249)
group by a.name;
count() does not count null values, which s.student_sid will be if no rows join from student.
You need to LEFT JOIN and then SUM() over the group where s.student_sid is not null:
select
a.name,
sum(case when s.student_sid is null then 0 else 1 end) as student_count
from account a
join inst i on a.inst_sid = i.root_inst_sid
join inst_year iy on i.inst_sid = iy.inst_sid
left join student s
on iy.inst_year_sid = s.inst_year_sid
and s.demo = 0
and s.state = 1
where i.state = 1
and iy.year_sid = 16
and a.account_sid in (20187987, 20188576, 20188755, 52317128, 20189249)
group by a.name;
This is assuming that all of the fields in the student table that you are filtering on are optional. If you don't want to enforce removal of records where, say, s.state does not equal 1, then you need to move the s.state=1 predicate into the WHERE clauses.
If, for some reason, you are getting duplicate student IDs and students are being counted twice, then you can change the aggregate function to this:
count(distinct s.student_id) as student_count
...which is safe to do as count(distinct ...) ignores null values.
In the results of my sql-statement (SQL Server 2016) I would like to combine two rows with the same value in two columns ("study_id" and "study_start") into one row and keep the row with higest value in a third cell ("Id"). If any columns (i.e. "App_id" or "Date_arrival) in the row with higest Id is NULL, then it should take the value from the row with the lowest "Id".
I get the result below:
Id study_id study_start Code Expl Desc Startmonth App_id Date_arrival Efter_op Date_begin

Many ways, this will work:
WITH subSource AS (
/* Your query here */
)
SELECT
s1.id,
/* all other columns work like this:
COALESCE(S1.column,s2.column)
for example: */
coalesce(s1.appid,s2.appid) as appid
FROM subSource s1
INNER JOIN subSource s2
ON s1.study_id =s2.study_id
and s1.study_start = s2.study_start
AND s1.id > s2.id
/* I imagine some other clauses might be needed but maybe not */
The rest is copy paste
I have 3 tables: firearms_firearmbook, inventory_inventory and inventory_inventorytransaction.
And i have 2 Cases:
If inventory_inventory Table has no inventory_inventorytransaction with item action of 16, show inventory_inventory record
If inventory_inventory Table has inventory_inventorytransaction with item action of 16, show inventory_inventory and inventory_inventorytransaction.item_action_id
The query bellow works for the first cause, but its not working for the second cause.
It should show smth like this:
-----------------------------------
| id | serial | action_id |
-----------------------------------
1 MAGUM
2 EAGLE
2 EAGLE 16
Query:
SELECT FB.id, INV.serial_number, INV.id, INVT.item_action_id FROM firearms_firearmbook AS FB
LEFT JOIN inventory_inventory AS INV ON INV.id = FB.item_id
LEFT JOIN inventory_inventorytransaction AS INVT ON INVT.item_id = INV.id AND INVT.item_action_id = 16
WHERE FB.store_id = 1
It seems that if there is an action 16 record for a given item, you need two records in the output: one with a blank in the third column, and one with 16 in the third column.
In that case you could do this:
with base as (
select fb.id,
inv.serial_number,
inv.id,
from firearms_firearmbook as fb
inner join inventory_inventory as inv
on inv.id = fb.item_id
where fb.store_id = 1
)
select base.*,
invt.item_action_id
from base
inner join inventory_inventorytransaction as invt
on invt.item_id = base.id
and invt.item_action_id = 16
union all
select base.*,
null
from base
order by 1, 2, 3, 4 desc
Hi I think this is what your after.
I've made a CASE statement for the two situation you describe. I wasn't sure what you column you wanted for 2) when you say "inventory_inventory" so I put the id column and you can change it for another column.
I've also removed INVT.item_action_id = 16 part of the inventory_inventorytransaction join as I don't think it's necessary as it is handled in the CASE statement.
SELECT
FB.id,
INV.serial_number,
INV.id,
INVT.item_action_id,
CASE
WHEN INVT.item_action_id = 16 THEN CAST(INV.id as VARCHAR) + ' ' + CAST(INVT.item_action_id as VARCHAR) -- This is Case 2
ELSE INV.record -- This is Case 1
END as answer
FROM firearms_firearmbook AS FB
LEFT JOIN inventory_inventory AS INV ON INV.id = FB.item_id
LEFT JOIN inventory_inventorytransaction AS INVT ON INVT.item_id = INV.id -- Removed JOIN on INVT.item_action_id = 16 and moved it to CASE
WHERE FB.store_id = 1;
