The below query taking more time to give results. This query in running inside the exists clause and also this query having stuff function.Is there any way to optimize or rewrite this query?.
AND EXISTS(SELECT 1
FROM
(SELECT DISTINCT
F_ALIAS,
F_DATA_CODE,
STUFF((SELECT ', ' + A.F_DATA
FROM T_REP_DATA A
WHERE A.F_ALIAS = RPDS.F_ALIAS
AND A.F_DATA_CODE = RPDS.F_DATA_CODE
AND '1:WVTST{PROD006' = A.F_ALIAS
FOR XML PATH(''), TYPE).value( '.', 'NVARCHAR(MAX)'), 1, 2, '') F_DATA
FROM T_REP_DATA RPDS
INNER JOIN
(SELECT DISTINCT F_CUSTOM2
FROM T_MSDSTYPES
WHERE (F_CUSTOM2 IS NOT NULL AND F_CUSTOM2 != '')) MT ON MT.F_CUSTOM2 = RPDS.F_DATA_CODE and RPDS.F_ALIAS = '1:WVTST{PROD006') RPDS_CUSTOM2)
WHERE RPDS_CUSTOM2.F_DATA LIKE 'MANU'
Your query is probably not correct at all (LIKE 'MANU' actually means = 'MANU'), but perhaps your query is doing (or is supposed to be doing) nothing more than this:
AND EXISTS(
SELECT 1
FROM T_REP_DATA RPDS
INNER JOIN T_MSDSTYPES MT
ON MT.F_CUSTOM2 = RPDS.F_DATA_CODE
WHERE RPDS.F_ALIAS = '1:WVTST{PROD006'
AND RPDS.F_DATA = 'MANU'
)
more specific answer requires more details.

I need to filter the results from my STUFF function which are held in the column 'combined_ops'. I need to only see records that do not contain the word 'Transfer'. I've tried the classic WHERE combined_ops NOT LIKE '%transfer%', but does not work. See my code and results and please let me know where I went wrong. Thank You.
SELECT Job, STUFF((SELECT DISTINCT ' ' + Operation_Service
FROM dbo.Job_Operation
WHERE dbo.Job_Operation.Job = dbo.Job.Job
for xml path('')),1,2,'') AS combined_ops
FROM dbo.Job
WHERE dbo.Job.Status = 'Active'
AND dbo.Job.Customer_PO = 'tmi stock'
enter image description here
There are a few ways to do this.
You can put the FOR XML in a CROSS APPLY and filter afterwards
SELECT
j.Job,
jo.combined_ops
FROM dbo.Job j
CROSS APPLY (SELECT
STUFF((SELECT DISTINCT ' ' + jo.Operation_Service
FROM dbo.Job_Operation jo
WHERE jo.Job = j.Job
for xml path(''), type
).value('text()[1]','nvarchar(max)'),1,2,'')
) AS jo(combined_ops)
WHERE j.Status = 'Active'
AND j.Customer_PO = 'tmi stock'
AND jo.combined_ops NOT LIKE '%transfer%'
Or you can use HAVING and conditional aggregation
SELECT Job,
STUFF((
SELECT ' ' + jo.Operation_Service
(
SELECT jo.Operation_Service
FROM dbo.Job_Operation jo
WHERE jo.Job = j.Job
GROUP BY jo.Operation_Service
HAVING COUNT(CASE WHEN jo.Operation_Service LIKE '%transfer%' THEN 1 END) = 0
) jo
for xml path(''), type
).value('text()[1]','nvarchar(max)'),1,2,'') AS combined_ops
FROM dbo.Job j
WHERE j.Status = 'Active'
AND j.Customer_PO = 'tmi stock'
Note the use of the syntax for xml path(''), type).value('text()[1]','nvarchar(max)') to unescape XML characters correctly.
Note also the use of table aliases rather than three part column names.
I am trying to get all route path separating with arrow (-->). But the arrow (-->) does not work, it is shown as -->.
SELECT
vrmd.LocationName + '--> '
FROM
dbo.tbl_VehicleRouteMapDetail vrmd
WHERE
vrmd.VrmapId = 1
ORDER BY
vrmd.VrmapId
FOR XML PATH('')
But it's working perfectly this way:
DECLARE #Route VARCHAR(MAX)= ''
SELECT #Route = #Route + vrmd.LocationName + '--> '
FROM dbo.tbl_VehicleRouteMapMaster vrmm
INNER JOIN dbo.tbl_VehicleRouteMapDetail vrmd ON vrmd.VrmapId = vrmm.VrmapId
ORDER BY vrmd.VrmapDetailId ASC
Why choose first query?
I need to use this query as subquery. In this case second query does not work for me:
SELECT
COUNT(ewva.VehicleId) Allocation, vii.Capacity,
STUFF((SELECT vrmd.LocationName + '=> '
FROM dbo.tbl_VehicleRouteMapDetail vrmd
WHERE vrmd.VrmapId = vrmm.VrmapId
ORDER BY vrmd.VrmapId
FOR XML PATH('')), 1, 1, '') AS name_csv
FROM
dbo.tbl_VehicleInfoInternal vii
INNER JOIN
dbo.tbl_EmpWiseVehicleAllocation ewva ON ewva.VehicleId = vii.VehicleId
INNER JOIN
dbo.tbl_VehicleRouteMapMaster vrmm ON vrmm.VehicleId = vii.VehicleId
GROUP BY
ewva.VehicleId, vii.Capacity, vrmm.VrmapId
Any help would be appreciated.
It's as simple as adding the TYPE directive to your FOR XML clause (docs here). This will return the result as an instance of the XML type rather than text. Text will have certain characters (e.g. > and <) translated (> and <) to fit within an XML element.
SELECT
vrmd.LocationName + '--> '
FROM
dbo.tbl_VehicleRouteMapDetail vrmd
WHERE
vrmd.VrmapId = 1
ORDER BY
vrmd.VrmapId
FOR XML
PATH(''), TYPE
I am trying to get some values from different rows into a single column, and I keep getting this error :
Invalid object name 't'
The query is rather big and complicated so I narrowed it down to a simple part that still gives me the error.
select
IDs = stuff( ( select ',' + convert(varchar, t2.ChassisID)
from t as t2
where t2.ChassisID = 42 --t.ChassisID
for XML path('')
)
, 1, 1, ''
)
from ( select ch.ChassisID, p.GPS
from tblChassis ch
inner join tblPlace p on ch.BestemmingID = p.PlaceID
) t
group by t.Gps
I tried changing the where clause to a fixed number (42) instead of t.ChassidID and still get the error, so there is only one place left that could cause the error I assume, but I cant see why.
I probably am missing something simple but I just cannot see it.
What is wrong with this query ?
I am using Sql Server 2014
Try declaring your filtered table in a CTE, then referencing this CTE both times.
;WITH FilteredChassis AS
(
select
ch.ChassisID,
p.GPS
from
tblChassis ch
inner join tblPlace p on ch.BestemmingID = p.PlaceID
)
select
t.Gps,
IDs = stuff( ( select ',' + convert(varchar, t2.ChassisID)
from FilteredChassis as t2
where t2.Gps = t.Gps
for XML path('')
)
, 1, 1, ''
)
from
FilteredChassis AS t
group by
t.Gps
I've made the link through gps, I believe that's what you need.
I am attempting the following query in SQL Server:
SELECT AlertID,
(STUFF((SELECT ', ' + t2.LocationDesc
FROM app_Location t2
WHERE t1.LocationCode = t2.LocationCode
FOR XML PATH (''))
, 1, 1, '')) as Location,
CensusTime,
InsertDate
FROM MultiCensusEmail
INNER JOIN app_Location t1 ON MultiCensusEmail.Location = t1.LocationCode
I want it to return a comma delimited list for the locations, but they are showing up on separate rows.
I want the row to end up something like this:
5A8056A7-5D8F-4678-B980-9E54987EE70C | AS EMERGENCY DEPT, BN CARDIAC,
BN CHEST PAIN UNIT | 7:00 | 2016-10-17 9:17:55.067
You don't provide much detail about your data, but I think that your JOIN is not needed.
SELECT AlertID,
(STUFF((SELECT ', ' + t2.LocationDesc
FROM app_Location t2
WHERE MultiCensusEmail.Location = t2.LocationCode // probably you want another condition here
FOR XML PATH (''))
, 1, 1, '')) as Location,
CensusTime,
InsertDate
FROM MultiCensusEmail
What do you want to "group by" (e.g. what data item does have multiple locations)?
The "outer" query should produce the wanted rows without "location" (in your case), and the "inner" FOR XML query should have a condition that filters the "locations" you want to have comma-separated.
I was able to accomplish what I wanted to do using COALESCE:
declare #Location varchar(max)
select #Location = COALESCE(#Location + ', ', '') + LocationDesc
From app_Location INNER JOIN MultiCensusEmail ON MultiCensusEmail.Location = app_Location.LocationCode
where upper(UserID) = 'test'
select distinct AlertID, #Location, CensusTime, InsertDate
from MultiCensusEmail
where upper(UserID) = 'test'
I am having a tricky time doing this so hopefully someone can help. This is what I want my end result to be:
SELECT 'PRODUCT' AS ItemType,
'x' + CAST(MB_StaticOrderProducts.Quantity AS varchar(50)),
MB_StaticOrderProducts.ProductName + ' (' + CAST((MB_StaticOrderProducts.ProductSize) AS varchar(50)) + ' ' + MB_StaticProductMeasure.Value + ')' AS Name,
MB_StaticOrderProducts.ProductSizeID,
GTIN as BarCode
FROM
MB_StaticOrderProducts
INNER JOIN MB_StaticOrderVersions ON MB_StaticOrderProducts.StaticOrderVersionId = MB_StaticOrderVersions.StaticOrderVersionId
INNER JOIN MB_StaticProductMeasure ON MB_StaticOrderProducts.StaticProductMeasureId = MB_StaticProductMeasure.StaticProductMeasureId
Inner Join ProductVariantAttributeCombination pvac on (pvac.Id = (select id from (select Id, cast(AttributesXml as xml) data from ProductVariantAttributeCombination) d cross apply data.nodes('//ProductVariantAttributeValue[Value[1] = 32]') data(d)))
WHERE
MB_StaticOrderProducts.StaticOrderVersionId = '8D803EAE-2CFC-455C-9CE7-0849618E1548'
I would like the column, MB_StaticOrderProducts.ProductSizeId to be in the 4th line of the From section, ProductVariantAttributeCombination, where the number 32 is. Is there a way to use the variable in that area?
For those that ever need it. I changed the data.nodes line to be:
data.nodes( '//ProductVariantAttributeValue[Value[1]
=sql:column("MB_StaticOrderProducts.ProductSizeID")]')
and all worked. Thanks.
Use the Concat function
Like this:
data.nodes( concat('//ProductVariantAttributeValue[Value[1] = ',
MB_StaticOrderProducts.ProductSizeId,
']')
