I have a sql query that I need to put into a view. I have it working as a stored procedure but my requirement is for it to be a View. This means I cant declare dynamic SQL as I have done in my stored procedure.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);

Please help me find an alternate way, but not store procedures. I need it in view
for a view it needs to be a single select statement,
your #cols statement returns a list of columns, this is used twice within your main select statement. so replacing #cols in your main query with the query that populates this should work.
set #query and then exec(#query) isnt necessary either so you just have to tidy up and make sure the right number of brackets are in place.
and it should look something like this.
SELECT Tran_Id
,Section_Id
,SubSection_Id
,R_Id,Hospital_Id
,Surgeon_Id,Procedure_ICD
,Procedure_Details
,DtSurgery_TimeIn
,DtSurgery_TimeOut

I am creating a web app in which I have a requirement where I want to display a column value as a header
Example
SELECT Name, Leave
FROM tblUser
INNER JOIN tblLeaveMaster ON tblUser.EmployeeID = tblLeaveMaster.EmployeeID
From that query, I get these results:
Name Leave
---------------
Test1 5
Test2 10
test3 2
Now I want to get these values as
Test1 Test2 Test3
-----------------
5 10 2
How can I achieve this?
You can try using pivot
select pv.* from
(SELECT Name,Leave
FROM tblUser INNER JOIN tblLeaveMaster ON tblUser.EmployeeID=tblLeaveMaster.EmployeeID
)X
pivot
(max(leave) for name in ([Test1],[Test2],[Test3])) as pv
For Dynamic PIVOT
declare #sql varchar(max)='',#col_list varchar(8000)=''
set #col_list = (select distinct quotename([Name])+',' from (SELECT Name,Leave
FROM tblUser INNER JOIN tblLeaveMaster ON tblUser.EmployeeID=tblLeaveMaster.EmployeeID
)X
for xml path(''))
set #col_list = left (#col_list,len(#col_list)-1)
set #sql = 'select '+#col_list+' from
(SELECT Name,Leave
FROM tblUser INNER JOIN tblLeaveMaster ON tblUser.EmployeeID=tblLeaveMaster.EmployeeID
)X
pivot (max([Leave]) for [Name] in ('+#col_list+'))pv'
exec(#sql)
try by using case when
select max( case when name='Test1' then Leave end) as test1,
max( case when name='Test2' then Leave end) as test2,
max( case when name='Test3' then Leave end) as test3 from
tblUser INNER JOIN tblLeaveMaster
ON tblUser.EmployeeID=tblLeaveMaster.EmployeeID
You can try to use condition aggregate function. CASE WHEN with MAX or MIN
SELECT
MAX(CASE WHEN Name = 'Test1' THEN Leave END) Test1,
MAX(CASE WHEN Name = 'Test2' THEN Leave END) Test2,
MAX(CASE WHEN Name = 'Test3' THEN Leave END) Test3
FROM tblUser
INNER JOIN tblLeaveMaster ON tblUser.EmployeeID=tblLeaveMaster.EmployeeID
EDIT
If your column want to create dynamic you can try to use Dynamic PIVOT
create your SQL statement and make condition aggregate function by connect SQL string. then use execute it Dynamically.
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
SET #cols = STUFF((SELECT distinct ', MAX(CASE WHEN Name = ''' + Name+''' THEN Leave END) ' + QUOTENAME(Name)
FROM tblUser
INNER JOIN tblLeaveMaster ON tblUser.EmployeeID=tblLeaveMaster.EmployeeID
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #query= 'SELECT '+ #cols+'
FROM tblUser
INNER JOIN tblLeaveMaster ON tblUser.EmployeeID=tblLeaveMaster.EmployeeID'
execute(#query)
sqlfiddle
You can find your result from the query as shown below. Here I have taken your query output in a temporary table.
Create table #finalData(ColName Varchar(30), Leave INT)
INSERT INTO #finalData Values('Test1', 5),('Test2', 10),('Test3', 2)
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX);
SET #cols = STUFF((SELECT distinct ',' + QUOTENAME(c.ColName)
FROM #finalData c
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT ' + #cols + ' from
(
select ColName
, Leave
from #finalData
) x
pivot
(
max(Leave)
for ColName in (' + #cols + ')
) p '
execute(#query)
DROP TABLE #finalData
Hope this will help you.
The output is as shown below
Test1 Test2 Test3
5 10 2
select pv.* from
(SELECT Name,Leave
FROM tblUser INNER JOIN tblLeaveMaster ON tblUser.EmployeeID=tblLeaveMaster.EmployeeID
)X
pivot
(max(leave) for name in ([Test1],[Test2],[Test3])) as pv
Note:- this work for me but how to use where condition base on dropdown list selected value.
eg: if wants to show only 2020 and not 2019.
This is my sample code:
SQL Fiddle
I need it to result like this:
category outlet1 outlet2 outlet3
Sale 70 20 40
Expense 250 130 200
How can I do this?
EDIT: My outlets are not fixed, sorry for not telling this beforehand.
You can solve your particular problem using conditional aggregation:
SELECT c.category,
SUM(CASE WHEN o.outletname = 'Outlet1' THEN t.amt ELSE 0 END) as Outlet1,
SUM(CASE WHEN o.outletname = 'Outlet2' THEN t.amt ELSE 0 END) as Outlet2,
SUM(CASE WHEN o.outletname = 'Outlet3' THEN t.amt ELSE 0 END) as Outlet3
FROM tblcategory c INNER JOIN
tbltran t
ON t.catid = c.id INNER JOIN
tbloutlet o
ON o.id = t.outletid
GROUP BY c.category;
If the outlet names are not fixed, then you need dynamic SQL. The problem cannot be solve using a single SELECT query.
Here with dynamic Outlets http://sqlfiddle.com/#!18/a7b09/25
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(outletname)
from tbloutlet
group by outletname
order by outletname
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT category,' + #cols + ' from
(
SELECT c.category, o.outletname, SUM(t.amt) as amt
FROM tblcategory c
INNER JOIN tbltran t ON t.catid = c.id
INNER JOIN tbloutlet o ON o.id = t.outletid
GROUP BY c.category, o.outletname
) x
pivot
(
sum(amt)
for outletname in (' + #cols + ')
) p '
execute(#query);
you may also use the PIVOT operator
SELECT *
FROM
(
SELECT category, outletname, amt
FROM tblcategory c
INNER JOIN tbltran t ON t.catid = c.id
INNER JOIN tbloutlet o ON o.id = t.outletid
) d
PIVOT
(
SUM(amt)
FOR outletname in ([Outlet1] , [Outlet2] , [Outlet3])
) p
EDIT : below is the Dynamic SQL version
declare #Outlets nvarchar(max),
#SQL nvarchar(max)
select #Outlets = isnull(#Outlets + ',', '') + quotename(outlet)
from outlet
select #SQL = '
SELECT *
FROM
(
SELECT category, outletname, amt
FROM tblcategory c
INNER JOIN tbltran t ON t.catid = c.id
INNER JOIN tbloutlet o ON o.id = t.outletid
) d
PIVOT
(
SUM(amt)
FOR outletname in (' + #Outlets + ')
) p'
print #SQL -- print out for verification
exec sp_executesql #SQL

I am attempting to use a Pivot to dynamically create columns and am not getting the proper results I am looking for. I need to show all possible answers in its own column for each question (row), and there are multiple questions in a course. How can I generate each possible answer as a column name, and filter by courseId and the questionId for each row? The number of possible answers varies based on the question. Should this be done via cursor instead of pivot?
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX),
#courseID float(24) = 1
SET #cols = STUFF((SELECT distinct ',' + QUOTENAME(questionID)
FROM answers
INNER JOIN questions ON questions.questionID = answers.questionID
WHERE questions.courseId = #courseID
order by 1
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
set #query = 'SELECT * from
(
select Q.courseId, C.courseName, Q.question, Q.questionID, A.answer
from questions Q
inner join courses C ON Q.courseId = C.courseId
inner join answers A ON A.questionID = Q.questionID
where (Q.courseId = ''' + Str(#courseID) + ''')
) x
pivot
(
max(answer)
for questionId in (' + #cols + ')
) AS p'
execute(#query)
When running the above I am getting:
[1],[10],[11],[12],[13],[14],[15],[16],[2],[3],[4],[5],[6],[7],[8],[9]
As the generated columns which are the questionIds and not 'Answer 1, Answer 2 ... etc', and they are not displaying in order.
For the sake of brevity here are the related columns in the database tables:
Courses
courseId
Questions
questionId question courseId
Answers
AnswerId questionId answer
Any help is appreciated.
You didn't provide a many details on your table structure, but if you want the answers as the columns i.e. Answer1, Answer2, etc then you need to create the columns using row_number() against the number of answers per question similar to the following:
SET #cols = STUFF((SELECT ',' + QUOTENAME('Answer'+cast(seq as varchar(10)))
FROM
(
select row_number() over(partition by q.questionid
order by a.answer) seq
from answers a
INNER JOIN questions q
ON q.questionID = a.questionID
WHERE q.courseId = #courseID
) d
group by seq
order by seq
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
, 1, 1, '');
This creates a sequence for each answer per question and then that sequence number is used to create the new columns names. Then you will alter your PIVOT code to:
set #query = 'SELECT *
from
(
select Q.courseId, C.className, Q.question, Q.questionID, A.answer,
''Answer''+cast(row_number() over(partition by q.questionid
order by a.answer) as varchar(10)) seq
from questions Q
inner join classes C
ON Q.courseId = C.courseId
inner join answers A
ON A.questionID = Q.questionID
where (Q.courseId = ''' + Str(#courseID) + ''')
) x
pivot
(
max(answer)
for seq in (' + #cols + ')
) AS p'
execute(#query)
I have a typical RDMS setup where records in a main table can have optional records in a related table via a M2M join. I'm trying to PIVOT this data but in cases where there is no relation I want to return a default value. The join I have below is returning NULL.
select *
from
(
SELECT s.Biz_Name, la.Name AS Association, ISNULL(i.Location, 'Default') as Location
FROM dbo.ShopAssociations sa
INNER JOIN dbo.LookupAssociations la
ON sa.AssociationID = la.AssociationID
RIGHT JOIN dbo.Basic_Shop_Info s
ON sa.ShopID = s.ShopID
INNER JOIN dbo.Images i
ON la.ImageID = i.ImageID
) DataTable
PIVOT
(
min(Location)
for association in
([OnCall],[OCGuy],[ASCLogo],[ASC_OtherSt],[ASE],[AASP],[AASP_PA],
[ASE_BlueSeal],[AAA],[AAA-B],[ASA],[ATRA],[ICAR],[CAA],[ACDelco],
[Cert],[ASC],[BBB],[Goodyear],[Limos],[RVs],[Bosch],[NARSA],
[DiscTire],[BigO],[Tires],[Firestone],[ASCCA],[JustTires],[ASE_Blue])
) PivotTable
The output looks like this:
BizName OnCall OCGuy ASCLogo ASC_OtherSt ASE ...
"Wonderful Biz" somevalue somevalue NULL somevalue NULL
What I am trying to achieve is if a child record doesn't exist in INNER JOIN from Basic_Shop_Info to ShopAssociations that we get "Default" instead of NULL. I've tried ISNULL(), Coalesce() and even a CASE statement, all with the same results.
Based on your comment it sounds like you found a solution. I am only answering this to provide a suggestion based on the fact you are pivoting so many columns and they are all hard-coded. You can use dynamic SQL for a PIVOT and your query would look something like this:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX),
#colsPivot AS NVARCHAR(MAX)
select #cols = STUFF((SELECT distinct ',' + QUOTENAME(Name)
from dbo.LookupAssociations
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
select #colsPivot = STUFF((SELECT distinct ', IsNull(' + QUOTENAME(Name) +', ''Default'')'
from dbo.LookupAssociations
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT Bizname, ' + #colsPivot + ' from
(
SELECT s.Biz_Name, la.Name AS Association, ISNULL(i.Location, ''Default'') as Location
FROM dbo.ShopAssociations sa
INNER JOIN dbo.LookupAssociations la
ON sa.AssociationID = la.AssociationID
RIGHT JOIN dbo.Basic_Shop_Info s
ON sa.ShopID = s.ShopID
INNER JOIN dbo.Images i
ON la.ImageID = i.ImageID
) x
pivot
(
min(Location)
for association in (' + #cols + ')
) p
'
execute(#query)
The value #colsPivot is adding the IsNull() around each of you columns so you can put in place the Default value. But this should provide the same result as your original query where everything was hard-coded.
This will get the list of columns at run-time so then you do not have to hard-code anything and it will accept new values without having to change the query.
I got this:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME(c.col+cast(rn as varchar(10)))

(
select row_number() over(partition by person_nbr
order by person_nbr,first_name, last_name, medication_name) rn

) c
group by col, rn, sort
order by rn, sort
FOR XML PATH(''), TYPE

set #query = 'SELECT person_nbr, first_name, last_name,medication_name,' + #cols + '
