I am getting the following error
"ORA-00923: FROM keyword not found where expected" while executing the query
SELECT
count(pf.pref_selection) filter ( WHERE pc.collection = "players") OVER (partition BY pc.collection,pc.user_id ) AS Avg_players
count(pf.pref_selection) filter ( WHERE pc.collection = "teams") OVER (partition BY pc.collection,pc.user_id ) AS Avg_teams
FROM NBA_OWNER.PREFERENCES pf
inner join NBA_OWNER.PREF_COLLECTIONS pc on pc.ID=pf.COLLECTION_ID
where pc.LAST_UPDATE_DATE>"30-SEP-16'`
You have several errors. As #cricket_007 pointed put you are missing a comma between the two count expressions. But you also have invalid syntax with your filter clause - which doesn't exist, at least in Oracle; you have used double quotes around string literals instead of single quotes; the quotes around your date string are even odder; and you are relying on NLS settings for the date format.
This is closer to what you need, if I understand what you were attempting:
SELECT
count(case when pc.collection = 'players' then pf.pref_selection end)
OVER (partition BY pc.user_id) AS Avg_players,
count(case when pc.collection = 'teams' then pf.pref_selection end)
OVER (partition BY pc.user_id) AS Avg_teams
FROM NBA_OWNER.PREFERENCES pf
inner join NBA_OWNER.PREF_COLLECTIONS pc on pc.ID=pf.COLLECTION_ID
where pc.LAST_UPDATE_DATE > date '2016-09-30'
The output might not be very useful though. For each user ID you may get multiple rows, each showing the total count (which you've called avg for some reason). You probably only want to see the counts for each ID once, and to see which ID they relate to, so I think you want an aggregate rather than analytic count:
SELECT
pc.user_id,
count(case when pc.collection = 'players' then pf.pref_selection end)
AS Avg_players,
count(case when pc.collection = 'teams' then pf.pref_selection end)
AS Avg_teams
FROM NBA_OWNER.PREFERENCES pf
inner join NBA_OWNER.PREF_COLLECTIONS pc on pc.ID=pf.COLLECTION_ID
where pc.LAST_UPDATE_DATE > date '2016-09-30'
group by pc.user_id

We have 2 Tables Lead and Task.
One lead can have multiple Tasks.
We want to determine if a Lead has a Task who's description contains String 'x'.
If the Lead has the String the it should belong to group1 if it doesn't to group2.
Then we want to count the leads per group and week.
The problem we have is that if a Lead has several tasks and one of them has string 'x' in its description and the others don't it is counted in both groups.
We would need something that resembles a break; statement in the IFF clause of the subquery, so that if the first condition = Contain string x is satisfied the other tasks are not counted anymore.
How would we achieve that?
So far we have the following statement:
--SQL:
SELECT LeadDate, GROUP, COUNT(LEAD_ID_T1)
FROM LEAD Lead INNER JOIN
(SELECT DISTINCT LEAD.ID AS LEAD_ID_T1,
IFF(CONTAINS(Task.DESCRIPTION,
'x'),
'GROUP1',
'GROUP2') AS GROUP
FROM TASK Task
RIGHT JOIN LEAD ON TASK.WHO_ID = LEAD.ID
) T1 ON T1.LEAD_ID_T1 = LEAD.ID
GROUP BY LeadDate,GROUP;
Code breaks because it can not aggregate the measures.
Really thankful for any input. This has been bothering me for a few days now.
I am thinking EXISTS with a CASE expression:
select l.*,
(case when exists (select 1
from task t
where t.who_id = l.id and
t.description like '%x%'
)
then 'GROUP1' else 'GROUP2'
end) as the_group
from lead l;
You can also try something like this, CASE with 1 and 0 then take the SUM
SELECT LeadDate,
sum(CASE When t.description like '%x%'then 1 else 0 end) as Group1,
sum(CASE When t.description like '%x%'then 0 else 1 end) as Group2
FROM TASK t
RIGHT JOIN LEAD l ON t.WHO_ID = l.ID
GROUP BY LeadDate;
I'm trying to write a query containing subqueries, which contain aggregate functions. I get an error message telling me that I should include some of my fields in the GROUP BY clause of my main query, in which I don't use any aggregates.
I'm pretty new at SQL so this might be a silly mistake but I have been on it for days and I can't figure it out with the existing content.
WITH B AS
(
SELECT
A.Week
,A.ASIN
,A.GL
,sum(Case when Week = 'W1' then Total_GV_Price/Total_GVs else 0 end) as Wk1_AVG
,sum(Case when Week = 'W2' then Total_GV_Price/Total_GVs else 0 end) as Wk2_AVG
FROM A
WHERE Total_GVs > 0
GROUP BY A.Week, A.ASIN, A.GL
)
, C AS
(
SELECT
B.Week
,B.ASIN
,B.GL
,B.Wk1_AVG
,B.Wk2_AVG
,Case when NVL(Wk1_AVG,0) =0 then NULL else (Wk2_AVG - Wk1_AVG) / Wk1_AVG end as Price_var
FROM B
GROUP BY B.Week, B.ASIN, B.GL, B.Wk1_AVG, B.Wk2_AVG
)
SELECT C.*
FROM C
HAVING Price_var >= 0.3
So the error message is telling me: column "c.week" must appear in the GROUP BY clause or be used in an aggregate function. And I don't understand what i'm not grouping or what I should be grouping.
I appreciate any comments and thank you for your help !
I'm not sure, because I can't reproduce the situation. But I think the problem lies in the SELECT ... FROM C at the end. You are using HAVING, which is used for aggregated columns (i.e. SUM(...)). Because the last SELECT has no aggregation a simple WHERE would suffice.
...
SELECT
C.*
FROM
C
WHERE Price_var >= 0.3
Hope this helps...
I have two tables, an Orders table which contains a list of a users orders and a OrderShippingCosts table which contains a price for shipping each item based on the OrderTypeID in the Orders table.
I am running a query like below to calculate the total shipping costs:
SELECT
SUM(CASE
WHEN OR.OrderTypeID = 1
THEN (SELECT CostOfShippingSmallParcel
FROM OrderShippingCosts)
ELSE (SELECT CostOfShippingBigParcel
FROM OrderShippingCosts)
END) AS TotalShippingCost
FROM
Orders AS OR
But I'm getting the following error:
Cannot perform an aggregate function on an expression containing an aggregate or a subquery
Does anyone know what is wrong with my query?
Function SUM takes an expression on input, which evaluates into single data value, not a dataset. Expression definition from MSDN:
Is a combination of symbols and operators that the SQL Server Database Engine evaluates to obtain a single data value.
You trying to pass to SUM function a dataset (which is result of subquery), not a single data value. This is simplification of what you trying to query:
SELECT SUM(SELECT Number FROM SomeTable)
It is not valid. The valid query would be:
SELECT SUM(Value) FROM SomeTable
In your particular case looks like you missing JOIN. Your original logic will result in summary of entire OrderShippingCosts table for each row of Orders table. I think, it should be something like this:
SELECT
SUM
(
CASE
WHEN ord.OrderTypeID = 1 THEN ship.CostOfShippingSmallParcel
ELSE ship.CostOfShippingBigParcel
END
) TotalShippingCost
FROM Orders AS ord
JOIN OrderShippingCosts ship ON /* your search condition, e.g.: ord.OrderID = ship.OrderID */
By the way, it is not a good idea to use reserved symbols as aliases, names and so on. In your query you use OR as alias for Orders table. Symbol OR is reserved for logical or operation. If you really need to use reserved symbol, wrap it into [ and ] square braces. Look here and here for more details.
The error message is clear, you can avoid it with a join:
SELECT
SUM(CASE WHEN [OR].OrderTypeID = 1
THEN CostOfShippingSmallParcel
ELSE CostOfShippingBigParcel END) AS TotalShippingCost
FROM Orders [OR]
CROSS JOIN OrderShippingCosts
You can try like this...
SELECT
CASE WHEN OR.OrderTypeID = 1
THEN (SELECT SUM(CostOfShippingSmallParcel) FROM OrderShippingCosts)
ELSE (SELECT SUM(CostOfShippingBigParcel) FROM OrderShippingCosts) END AS TotalShippingCost
FROM Orders AS OR
Let me know
select sum (or.TotalShippingCost)
FROM
SELECT
(CASE WHEN OR.OrderTypeID = 1
THEN (SELECT CostOfShippingSmallParcel FROM OrderShippingCosts)
ELSE (SELECT CostOfShippingBigParcel FROM OrderShippingCosts) END) AS TotalShippingCost
FROM Orders AS OR
Try this
SELECT
ISNULL
(
SUM
(
CASE
WHEN O.OrderTypeID = 1 THEN C.CostOfShippingSmallParcel
ELSE C.CostOfShippingBigParcel END
), 0
) AS TotalShippingCost
FROM
Orders AS O LEFT JOIN
OrderShippingCosts C ON O.Id = C.OrderId -- Your releation id
I'll try to describe as best I can, but it's hard for me to wrap my whole head around this problem let alone describe it....
I am trying to select multiple results in one query to display the current status of a database. I have the first column as one type of record, and the second column as a sub-category of the first column. The subcategory is then linked to more records underneath that, distinguished by status, forming several more columns. I need to display every main-category/subcategory combination, and then the count of how many of each sub-status there are beneath that subcategory in the subsequent columns. I've got it so that I can display the unique combinations, but I'm not sure how to nest the select statements so that I can select the count of a completely different table from the main query. My problem lies in that to display the main category and sub category, I can pull from one table, but I need to count from a different table. Any ideas on the matter would be greatly appreciated
Here's what I have. The count statements would be replaced with the count of each status:
SELECT wave_num "WAVE NUMBER",
int_tasktype "INT / TaskType",
COUNT (1) total,
COUNT (1) "LOCKED/DISABLED",
COUNT (1) released,
COUNT (1) "PARTIALLY ASSEMBLED",
COUNT (1) assembled
FROM (SELECT DISTINCT
(t.invn_need_type || ' / ' || s.code_desc) int_tasktype,
t.task_genrtn_ref_nbr wave_num
FROM sys_code s, task_hdr t
WHERE t.task_genrtn_ref_nbr IN
(SELECT ship_wave_nbr
FROM ship_wave_parm
WHERE TRUNC (create_date_time) LIKE SYSDATE - 7)
AND s.code_type = '590'
AND s.rec_type = 'S'
AND s.code_id = t.task_type),
ship_wave_parm swp
GROUP BY wave_num, int_tasktype
ORDER BY wave_num

Guessing a bit,both regarding your problem and Oracle (which I've - unfortunately - never used), hopefully it will give you some ideas. Sorry for completely messing up the way you write SQL, SELECT ... FROM (SELECT ... WHERE ... IN (SELECT ...)) simply confuses me, so I have to restructure:
with tmp(int_tasktype, wave_num) as
(select distinct (t.invn_need_type || ' / ' || s.code_desc), t.task_genrtn_ref_nbr
from sys_code s
join task_hdr t
on s.code_id = t.task_type
where s.code_type = '590'
and s.rec_type = 'S'
and exists(select 1 from ship_wave_parm p
where t.task_genrtn_ref_nbr = p.ship_wave_nbr
and trunc(p.create_date_time) = sysdate - 7))
select t.wave_num "WAVE NUMBER", t.int_tasktype "INT / TaskType",
count(*) TOTAL,
sum(case when sst.sub_status = 'LOCKED' then 1 end) "LOCKED/DISABLED",
sum(case when sst.sub_status = 'RELEASED' then 1 end) RELEASED,
sum(case when sst.sub_status = 'PARTIAL' then 1 end) "PARTIALLY ASSEMBLED",
sum(case when sst.sub_status = 'ASSEMBLED' then 1 end) ASSEMBLED
from tmp t
join sub_status_table sst
on t.wave_num = sst.wave_num
group by t.wave_num, t.int_tasktype
order by t.wave_num
As you notice, I don't know anything about the table with the substatuses.
You can use inner join, grouping and count to get your result:
suppose tables are as follow :
cat (1)--->(n) subcat (1)----->(n) subcat_detail.
so the query would be :
select cat.title cat_title ,subcat.title subcat_title ,count(*) as cnt from
cat inner join sub_cat on cat.id=subcat.cat_id
inner join subcat_detail on subcat.ID=am.subcat_detail_id
group by cat.title,subcat.title
Generally when you need different counts, you need to use the CASE statment.
select count(*) as total
, case when field1 = "test' then 1 else 0 end as testcount
, case when field2 = 'yes' then 1 else 0 endas field2count
FROM table1
I don't understand the purpose of using syntax code "CASE GROUPING"?
Unfortunately, I don't have the database to review the sourcecode below.
SELECT
CASE GROUPING(st.stor_name) WHEN 0 THEN st.stor_name ELSE 'ALL' END AS Store,
CASE GROUPING(s.type) WHEN 0 THEN s.type ELSE 'ALL TYPES' END AS Type,
SUM(s.qty) AS TotalSold
FROM
(SELECT DISTINCT st.stor_id, t.type, 0 AS qty
FROM stores st CROSS JOIN titles t
UNION ALL
SELECT
s.stor_id,
t.type, s.qty
FROM sales s JOIN titles t ON s.title_id=t.title_id) s
JOIN stores st ON (s.stor_id=st.stor_id)
GROUP BY st.stor_name, s.type WITH CUBE
CASE is a conditional expression, like an if statement.
GROUPING is a function that:
Indicates whether a specified column expression in a GROUP BY list is aggregated or not. GROUPING returns 1 for aggregated or 0 for not aggregated in the result set. GROUPING can be used only in the SELECT list, HAVING, and ORDER BY clauses when GROUP BY is specified.
