I have a case statement that is not returning a null value. What am I missing in to get this to work.
Select CASE
WHEN transfer_sources.input_lot_type = 'Dried' THEN Sum(transfer_sources.weight)
WHEN transfer_sources.input_lot_type = 'Fresh' THEN NULL
END
from transfer_sources join bulk_lots on transfer_sources.source_id = bulk_lots.id
where transfer_sources.input_lot_type = 'Dried' and bulk_lots.name = 'BS190208-010'
group by transfer_sources.input_lot_type
LIMIT 1
I would like a null to show in the fresh column as i am trying to only calculate for dried
You need to remove WHERE condition transfer_sources.input_lot_type = 'Dried':
Select CASE
WHEN transfer_sources.input_lot_type = 'Dried' THEN Sum(transfer_sources.weight)
WHEN transfer_sources.input_lot_type = 'Fresh' THEN NULL
END
from transfer_sources join bulk_lots on transfer_sources.source_id = bulk_lots.id
where bulk_lots.name = 'BS190208-010'
group by transfer_sources.input_lot_type

I have a question about query time. This 'view' has +1M data and when you execute select*from view , its query time is +400 seconds. On my query, it returns 10k data and query time is around 8-10 seconds. I am looking for a way to decrease it to 1 or 2 seconds. I tried changing or deleting things in my where or select clause, but only solution i came up with is limiting between "time" part.
If anyone know a better solution, that would be appreciated!
Thanks,
Can
Note: This view contains three different tables(cl_segments,cl_participants,cl_party_info).
I could not find a definition for those tables but i will add pictures of indexes and fields. Please let me know if you need any additional information.

I would like to ask if it is possible to select again from a result set if a column contains a specific value?
For example, from the below query I want to select it as subquery and check if that subquery's first column contains both 2 and 3 result. Otherwise, no values should be return.
select e.evaluator_id, ROUND(avg(cast(e.rating_score as int))::numeric,1)::varchar, c.q_category_name
from tms.t_evaluation e
inner join tms.m_q_category c
on e.nendo=c.nendo
and e.q_category_id = c.q_category_id
and c.delete_flg = '0'
inner join tms.m_q_subcategory qs
on e.q_category_id = qs.q_category_id
and e.q_subcategory_id = qs.q_subcategory_id
and c.nendo = qs.nendo
and qs.delete_flg = '0'
where e.nendo = '2018'
and e.empl_id = 'empl05'
and e.delete_flg = '0'
and e.evaluator_id in ('2' , '3')
group by e.empl_id, e.nendo, e.q_category_id,
c.q_category_name, e.evaluator_id, e.history_no
Result contains both 2 and 3 in first column. Is this possible?
select e.evaluator_id, ROUND(avg(cast(e.rating_score as int))::numeric,1)::varchar, c.q_category_name
from tms.t_evaluation e
inner join tms.m_q_category c
on e.nendo=c.nendo
and e.q_category_id = c.q_category_id

I have the following query:
var newsItems = tree.SelectNodes()
.Types(pageTypesArray)
.Path(path)
.OrderBy(orderBy)
.CombineWithDefaultCulture(false)
.Page(page, count)
.OnCurrentSite()
.NestingLevel(-1)
.Culture(CurrentDocument.DocumentCulture)
.InCategories(categories)
.TopN(topN)
.Where("ListableDocumentImage is not null AND ListableDocumentImage != ''")
.Columns(columns);
Which translates like so:
WITH AllData AS
(
SELECT TOP 6 * for brevity, ROW_NUMBER() OVER (ORDER BY [NewsOccurrenceDate] DESC) AS [CMS_RN]
FROM View_CMS_Tree_Joined AS V WITH (NOLOCK, NOEXPAND) INNER JOIN SOS_News AS C WITH (NOLOCK) ON [V].[DocumentForeignKeyValue] =
[C].[NewsID] AND V.ClassName = N'News' LEFT OUTER JOIN COM_SKU AS S WITH (NOLOCK) ON [V].[NodeSKUID] = [S].[SKUID]
WHERE [NodeSiteID] = #NodeSiteID AND (([DocumentCanBePublished] = 1 AND ([DocumentPublishFrom] IS NULL OR [DocumentPublishFrom] <= #Now)
AND ([DocumentPublishTo] IS NULL OR [DocumentPublishTo] >= #Now))
AND [NodeAliasPath] LIKE #NodeAliasPath AND [DocumentCulture] = #DocumentCulture
**AND 0 = 1)** <<<------------------- WHERE DID THIS COME FROM?????
)
SELECT *, (SELECT COUNT(*) FROM AllData) AS [CMS_TOT]
FROM AllData
WHERE CMS_RN BETWEEN 4 AND 6
ORDER BY CMS_RN
Has anyone ever come across anything like this before? I can't figure out why they're sticking in the AND 0=1 in my where clause.
Properly structuring your document API call will help with this. In your query results, you can see your WHERE condition is not even being added so it does make a difference the order of the methods being called.
For instance:
var newsItems = tree.SelectNodes()
.Types(pageTypesArray)
.Path(path)
.Where("ListableDocumentImage is not null AND ListableDocumentImage != ''")
.TopN(topN)
.OrderBy(orderBy)
.CombineWithDefaultCulture(false)
.Page(page, count)
.NestingLevel(-1)
.Culture(CurrentDocument.DocumentCulture)
.InCategories(categories)
.OnCurrentSite()
.Columns(columns);
How is it that this is valid:
ALTER PROCEDURE [StoredProcedure]
#abcID int = null -- optional param
SELECT columnJ, columnK, Count(eID) AS Num, Sum(OutXYZ) as TotalProdXYZ, Sum(RawXYZ) as TotalRawXYZ
FROM [v_ViewTable]
WHERE (#abcID IS NULL OR (abcID = #abcID))
GROUP BY columnJ, columnK
But then this is throwing a "columnJ is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause."
ALTER PROCEDURE [StoredProcedure]
#abcID int = null -- optional param
-- if 0: Group by columnJ, columnK
-- else: Group by columnK, columnJ
, #Grouping int = null
SELECT columnJ, columnK, Count(eID) AS Num, Sum(OutXYZ) as TotalProdXYZ, Sum(RawXYZ) as TotalRawXYZ
FROM [v_ViewTable]
WHERE (#abcID IS NULL OR (abcID = #abcID))
GROUP BY
CASE WHEN #Grouping = 0 THEN columnJ ELSE columnK END
,CASE WHEN #Grouping = 0 THEN columnK ELSE columnJ END
What's wrong with my CASE statement? Basically, if #Grouping = 0, I want the group by to be J, K if anything else, it should be K, J
Thanks in advance for any help!
As the message says columnJ and columnK are not contained in either an aggregate function or the GROUP BY clause in the second case. You should use field or the exact expression in select list AS IS in the GROUP BY section.
So the following statement will be ok:
SELECT CASE WHEN #Grouping = 0 THEN columnJ ELSE columnK END,
CASE WHEN #Grouping = 0 THEN columnK ELSE columnJ END,
Count(eID) AS Num, Sum(OutXYZ) as TotalProdXYZ, Sum(RawXYZ) as TotalRawXYZ
FROM [v_ViewTable]
WHERE (#abcID IS NULL OR (abcID = #abcID))
GROUP BY
CASE WHEN #Grouping = 0 THEN columnJ ELSE columnK END
,CASE WHEN #Grouping = 0 THEN columnK ELSE columnJ END
Im using query in crystal report like:
if({?User Name}) <>"ALL"
then
{COMN_USER_RESP_LINK_T.APPL_USER_NAME}={?User Name}
else
{COMN_USER_RESP_LINK_T.APPL_USER_NAME} ={COMN_USER_RESP_LINK_T.APPL_USER_NAME}
and
{COMN_USER_RESP_LINK_T.ENABLED}="Y"
this is actual query in sql:
SELECT
C.APPL_USER_NAME,
A.RESP_NAME,
B.MENU_NAME,
B.DESCRIPTION,
B.MODULE_NAME,
C.APPL_RESP
FROM COMN_RESPONSIBILITY_T A,
COMN_RESP_MENU_LINK_T B,
COMN_USER_RESP_LINK_T C
WHERE A.COMP_CODE = B.COMP_CODE
AND B.COMP_CODE = C.COMP_CODE
AND C.COMP_CODE = A.COMP_CODE
AND A.RESP_NAME = B.RESP
AND C.APPL_RESP = A.RESP_NAME
AND B.ENABLED = 'Y'
AND C.APPL_USER_NAME = c.APPL_USER_NAME
CASE #ACCT_CODE_FROM
WHEN 'ALL' THEN C.APPL_USER_NAME
ELSE #ACCT_CODE_FROM
END
ORDER BY APPL_USER_NAME,
RESP_NAME
I should select user name in parameter field(?user name), if I select ALL then I have to show all records ({COMN_USER_RESP_LINK_T.APPL_USER_NAME})
is the above query correct?
I would probably rephrase that as something like:
SELECT C.APPL_USER_NAME, A.RESP_NAME, B.MENU_NAME, B.DESCRIPTION,
B.MODULE_NAME, C.APPL_RESP
FROM COMN_RESPONSIBILITY_T A
INNER JOIN COMN_RESP_MENU_LINK_T B ON A.COMP_CODE = B.COMP_CODE
AND A.RESP_NAME = B.RESP
INNER JOIN COMN_USER_RESP_LINK_T C ON B.COMP_CODE = C.COMP_CODE
AND C.APPL_RESP = A.RESP_NAME
WHERE ((#ACCT_CODE_FROM = 'ALL') AND (B.ENABLED = 'Y'))
OR (C.APPL_USER_NAME = #ACCT_CODE_FROM)
ORDER BY APPL_USER_NAME, RESP_NAME
This gets you the details for either:
when ALL is selected, all accounts that are enabled; or
just the user code entered
i don't read your code because it is very dirty! but i think you can use SelectionFormula in crystal report. Certainly you can set it in code :
crystalReportViewer1.SelectionFormula ="(({?User Name}= 'ALL') AND ({B.ENABLED} = 'Y'))
OR ({C.APPL_USER_NAME} = #ACCT_CODE_FROM)"
