I have never used Case before and am not sure how to do this but we have had some issues doing a wholesale update because of addresses changing that are now coming in the data that did not used to. I am trying to use it as an if then statement but I am sure that I am doing wrong. I need to update addresses when a field is either empty or null.
UPDATE defendants_ALL_Fixed
SET tiffAdd = tiffAdds.Add1, tiffZip = tiffAdds.Zip, tiffCity = tiffAdds.City, tiffState = tiffAdds.State
FROM defendants_ALL_Fixed INNER JOIN
tiffAdds ON defendants_ALL_Fixed.tiff = tiffAdds.Tiff
WHERE (defendants_ALL_Fixed.tiff = tiffAdds.Tiff)
I have tried wrapping that into a case statement such as:
SELECT
a.tiffAdd
, CASE WHEN a.tiffAdd = '' THEN
UPDATE defendants_ALL_Fixed
SET tiffAdd = tiffAdds.Add1, tiffZip = tiffAdds.Zip, tiffCity = tiffAdds.City, tiffState = tiffAdds.State
FROM defendants_ALL_Fixed INNER JOIN
tiffAdds ON defendants_ALL_Fixed.tiff = tiffAdds.Tiff
WHERE (defendants_ALL_Fixed.tiff = tiffAdds.Tiff)
END
FROM defendants_ALL_Fixed a
Which did not work and I understand why it does not work but have no idea where to go from here and any help would be great. We only use this once a month to update data (about 1.5 million records) and the resources it uses is not at all relevant at this point.
Thanks.
Assuming i am understanding your question (i.e. only update defendants_ALL_Fixed fields with tiffAdds when the defendants_ALL_Fixed fields are blank), you could do this as follows (sticking with case):
UPDATE defendants_ALL_Fixed
SET tiffAdd = CASE WHEN LTRIM(RTRIM(ISNULL(tiffAdd, ''))) = '' THEN tiffAdds.Add1
ELSE tiffAdd
END ,
tiffZip = CASE WHEN LTRIM(RTRIM(ISNULL(tiffZip, ''))) = '' THEN tiffAdds.Zip
ELSE tiffZip
END ,
tiffCity = CASE WHEN LTRIM(RTRIM(ISNULL(tiffCity, ''))) = '' THEN tiffAdds.City
ELSE tiffCity
END ,
tiffState = CASE WHEN LTRIM(RTRIM(ISNULL(tiffState, ''))) = '' THEN tiffAdds.State
ELSE tiffState
END
FROM defendants_ALL_Fixed
INNER JOIN tiffAdds ON defendants_ALL_Fixed.tiff = tiffAdds.Tiff
A simpler (or rather, easier to read) option is to do simple update statements based on a WHERE clause (one update statement per column):
UPDATE defendants_ALL_Fixed
SET tiffAdd = tiffAdds.Add1
FROM defendants_ALL_Fixed
INNER JOIN tiffAdds ON defendants_ALL_Fixed.tiff = tiffAdds.Tiff
WHERE ( LTRIM(RTRIM(ISNULL(tiffAdd, ''))) = '' )
Edit 1: based on your comment, That would suggest you can just update all columns where tiffAdd = ''? i.e.
UPDATE defendants_ALL_Fixed
SET tiffAdd = tiffAdds.Add1 ,
tiffZip = tiffAdds.Zip ,
tiffCity = tiffAdds.City ,
tiffState = tiffAdds.State
FROM defendants_ALL_Fixed
INNER JOIN tiffAdds ON defendants_ALL_Fixed.tiff = tiffAdds.Tiff
WHERE LTRIM(RTRIM(ISNULL(tiffAdd, ''))) = ''
Why dont you use merge instead? Use merge on every each field, checking if the value is not null or empty. I think it wpould be the best (used it on my own solution).

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 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

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?

Thank you very much in advance.
I have a query in access which i need to convert to a stored proc in sql server 2005.
the query in access is as follows:
UPDATE
tblitem,
tblFileSignature
SET
tblitem.strFileProcesstype = [tblFileSignature].[STRFILEPROCESSTYPE], tblitem.strFileSignatureType = [tblFileSignature].[strfilesignaturetype]
WHERE
(((tblitem.strFileSignatureType) Is Null) AND
((tblitem.strFileExclude)="n") AND
((InStr([tblitem].[strfilesignature],[tblFileSignature].[strsignature]))=1) AND ((tblitem.uidItemType)=1 Or (tblitem.uidItemType)=5) AND
((tblitem.uidCollection)=[forms]![frmSetup]![txtInputCol]) AND ((tblitem.strFileSignature) Not Like "d0c*") AND
((tblFileSignature.strFileProcessType) Not Like "ZIP"));
in tsql.. would this be the same?
update tblItem
set
i.strFileProcesstype = f.strFileProcesstype,
i.strFileSignatureType = f.strfilesignaturetype
from tblItem as I UNION tblFileSignature as F
WHERE (((i.strFileSignatureType) Is Null) AND
((i.strFileExclude)="n") AND
((i.[strfilesignature] like F.strsignature)) AND
((i.uidItemType)=1 Or
(i.uidItemType)=5) AND
((i.uidCollection)=#inputcolumn AND
((i.strFileSignature) Not Like 'd0c%') AND
((F.strFileProcessType) Not Like 'ZIP'));
thanks in advance
UPDATE:
so i'm going with the following. if i uncomment the declare and select clause and just execute from the declare down, it runs, if i comment the declare and select parts, it says error near ';'.
UPDATE I
SET
I.strFileProcesstype = F.STRFILEPROCESSTYPE,
I.strFileSignatureType = F.strfilesignaturetype
--declare #uidcollectionID int
--select I.strFileSignatureType
from
tblItem I
inner join tblFileSignature F
on
I.strfilesignature = left(F.strsignature,len(I.strfilesignature))
WHERE I.strFileSignatureType Is Null
AND I.strFileExclude='n'
AND I.uidItemType in (1,5)
AND I.uidCollection = #uidCollectionID
AND left(I.strFileSignature,3) <> 'd0c'
AND F.strFileProcessType <> 'ZIP';
any ideas?
You should change the
Double Quotes to Single Quotes
* to %
Replace the InStr with LIKE
Other than that, it looks fine to me.
No, you'd use a JOIN, not a UNION.
You can either make it a CROSS JOIN, and continue to apply the join conditions in the WHERE clause, or you can make it an inner join:
from tblItem as I INNER JOIN tblFileSignature as F
ON ((InStr(i.[strfilesignature],F.[strsignature]))=1)
And remove that condition from the WHERE clause (Lieven's answer also applies).
This should be close to what you need. May need to work on the join condition, but I think my conversion from INSTR will do it.
UPDATE i
SET strFileProcesstype = fs.STRFILEPROCESSTYPE,
strFileSignatureType = fs.strfilesignaturetype
FROM tblitem i
INNER JOIN tblFileSignature fs
ON i.strfilesignature = LEFT(fs.strsignature, LEN(i.strfilesignature))
WHERE i.strFileSignatureType IS Null
AND i.strFileExclude='n'
AND i.uidItemType IN (1,5)
AND i.uidCollection = #inputcolumn
AND LEFT(i.strFileSignature,3) <> 'd0c'
AND fs.strFileProcessType <> 'ZIP';
