I'm creating a report in SSRS and want to have a multiple value parameter but allow blank values (''), and display all records when blank.
The gist of it is:
SELECT *
FROM Products p
JOIN ProductCategories c on c.ProductId = p.Id
WHERE (c.Name IN (#Categories) OR #Categories = '')
Which works when blank, and works with 1 category, but errors out with 2 categories. We got around this by using a temp table, but that solution seemed sort of hacky, so I wanted to see if there was a better way to resolve this.
The temp table workaround we built was this:
CREATE TABLE #temp (ProductId INT, Category NVARCHAR(MAX))
INSERT INTO #temp
SELECT p.Id, c.Name
FROM Products p
JOIN ProductCategories c on c.ProductId = p.Id
WHERE c.Name IN (#Categories)
IF ((SELECT COUNT(*) FROM #temp) = 0)
BEGIN
INSERT INTO #temp
SELECT p.Id, c.Name
FROM Products p
JOIN ProductCategories c on c.ProductId = p.Id
WHERE c.Name LIKE '%'
END
SELECT * FROM #temp
Thanks in advance!
If you don't have a split/parse function
Example
...
Where #Categories = ''
or
C.Name in (
Select RetVal = ltrim(rtrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace((Select replace(#Categories,',','§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as A
Cross Apply x.nodes('x') AS B(i)
)
Here is a dbFiddle ... You'll notice Poultry was excluded, then try it when #Categories=''

SQL Server recursive self join
(1 answer)
Closed 3 years ago.
I have a SQL Server table that holds groups and subgroups that I am using to define user permissions in application. What I am trying to accomplish is to select all users ids from all subgroups based on used id assigned to group.
I have tried with this query but it only shows one level of subgroup users.
SET #UserIds =
ISNULL(
STUFF((SELECT ',' + CAST(tbl.UserID AS VARCHAR(MAX))
FROM
(SELECT grpUser.UserId AS UserID
FROM dbo.GroupUser grpUser
INNER JOIN (SELECT subGrp.Id, subGrp.GroupName
FROM dbo.Groups grp
INNER JOIN dbo.GroupUser guser ON grp.Id = guser.GroupId
AND guser.UserId = #UserId
INNER JOIN dbo.Groups subGrp ON grp.Id = subGrp.ParentGroupId) tbl ON grpUser.GroupId = tbl.Id) AS tbl
FOR XML PATH('')), 1, 1, ''), '')
I am struggling to get users ids in all subgroups. Number of subgroups is not defined. Is there a way to do in sql or should I shift this part to application side? Thank you for any advice.
Finally I came up with this code. Thank you for hint.
declare #UserGroupId int;
Set #UserGroupId = (Select GroupId from GroupUser gu
left join dbo.Groups gr on gu.GroupId = gr.id
where UserId = #UserId and gr.IsDeleted = 0)
declare #UsersGroups Table (
Id int not null,
GroupName nvarchar(50) not null
)
;WITH grp AS
(
SELECT Id, GroupName
FROM Groups
WHERE ParentGroupId = 1
UNION ALL
SELECT g.Id, g.GroupName
FROM Groups g
INNER JOIN dbo.GroupUser guser ON g.Id = guser.GroupId
INNER JOIN grp ON g.ParentGroupId = grp.Id
)
Insert into #UsersGroups
SELECT Id, GroupName
FROM grp
SET #UserIds = ISNULL(STUFF(( SELECT ',' + CAST(tbl.UserID AS VARCHAR(max)) FROM (
SELECT grpUser.UserId AS UserID FROM dbo.GroupUser grpUser
INNER JOIN ( SELECT * FROM #UsersGroups
) tbl ON grpUser.GroupId = tbl.Id
) AS tbl FOR XML PATH('') ), 1, 1, ''), '')
I have a table called items which has a parent/child relation that I am converting to a hierarchyid.
I have followed this tutorial to do so.
All the steps of the tutorial works, except the final update statement.
I get the error message:
Implicit conversion from data type hierarchyid to nvarchar(max) is not allowed. Use the CONVERT function to run this query.
But this makes no sense. The field I am updating is a hierarchyid, not an nvarchar(nax). So I don't see where an nvarchar(max) field is involved.
drop table #children
CREATE TABLE #Children
(
ID int,
TenantId int,
ParentID int,
Num int
);
GO
CREATE CLUSTERED INDEX tmpind ON #Children(TenantId, ParentID, ID);
GO
INSERT #Children (ID, TenantId,ParentID, Num)
SELECT ID, TenantId, ParentID,
ROW_NUMBER() OVER (PARTITION BY TenantId, ParentID ORDER BY ParentId)
FROM Items
GO
SELECT * FROM #Children ORDER BY TenantId, ParentID, Num
GO
WITH paths(path, ID, ParentId, TenantId)
AS (
-- This section provides the value for the root of the hierarchy
SELECT hierarchyid::GetRoot() AS OrgNode, ID, ParentId, TenantId
FROM #Children AS C
WHERE ParentId IS NULL
UNION ALL
-- This section provides values for all nodes except the root
SELECT
CAST(p.path.ToString() + CAST(C.Num AS varchar(30)) + '/' AS hierarchyid),
C.ID , C.ParentId, C.TenantId
FROM #Children AS C
JOIN paths AS p
ON C.ParentID = P.ID
)
-- This select statement runs just fine and shows expected data.
--Select i.Id as ItemId, p.path, p.path.ToString() as LogicalNode, p.Id, p.ParentId, p.TenantId from Paths P
--join Items I on p.Id = i.Id
--order by P.TenantId, P.path
--Note that I have tried using the convert function, but it still fails with the same error message.
UPDATE I Set OrgNode = Convert(hierarchyid, P.path)
FROM Items I
JOIN Paths AS P
ON I.ID = P.ID
GO
EDIT
Strangely, this DBFiddle works.
It looks like column OrgNode is not of type hierachyid. You could use ToString()
UPDATE I Set OrgNode = P.path.ToString()
FROM Items I
JOIN Paths AS P
ON I.ID = P.ID
or alter table Items and change column type.
It looks like you solved your problem, but I would suggest saving the conversion to hierarchyid to the end. Like this:
WITH paths(path, ID, ParentId, TenantId)
AS (
-- This section provides the value for the root of the hierarchy
SELECT cast('/' as varchar(max)) AS OrgNode, ID, ParentId, TenantId
FROM #Children AS C
WHERE ParentId IS NULL
UNION ALL
-- This section provides values for all nodes except the root
SELECT
CAST(concat(p.path.ToString(), C.Num, '/') AS varchar(max)),
C.ID , C.ParentId, C.TenantId
FROM #Children AS C
JOIN paths AS p
ON C.ParentID = P.ID
)
-- This select statement runs just fine and shows expected data.
--Select i.Id as ItemId, p.path, p.path.ToString() as LogicalNode, p.Id, p.ParentId, p.TenantId from Paths P
--join Items I on p.Id = i.Id
--order by P.TenantId, P.path
--Note that I have tried using the convert function, but it still fails with the same error message.
UPDATE I Set OrgNode = Convert(hierarchyid, P.path)
FROM Items I
JOIN Paths AS P
ON I.ID = P.ID
GO
Note, I also changed the + style of concatenation for the concat() function so you don't have to mess around with converting C.Num to a varchar.
I have 2 tables:
contains full tree data
contains only specific childs
I need to get full hierarchy by child values. I can do it by one specific child node by following way:
;with tree as
(
select id, parent_id, name, level from f_all where id = #specefic_id
union all
select f.id, f.parent_id, f.name, f.level from f_all f
inner join tree t on f.id = t.parent_id and f.id <> f.parent_id
)
select *
from tree
OPTION (Maxrecursion 0)
I have an idea but I think it is not good. My idea is create function with above code. And call it by select my second table. I even didn't try it. Can you give me a right direction.
This is 2012+ ( Using concat() ... easily converted ).
Declare #f_all table (id int,parent_id int,name varchar(50))
Insert into #f_all values
(1,null,'1'),(2,1,'2'),(3,1,'3'),(4,2,'4'),(5,2,'5'),(6,3,'6'),(7,null,'7'),(8,7,'8')
Declare #Top int = null --<< Sets top of Hier Try 9
Declare #Nest varchar(25) = '|-----' --<< Optional: Added for readability
Declare #Filter varchar(25) = '4,6' --<< Empty for All or try 4,6
;with cteP as (
Select Seq = cast(1000+Row_Number() over (Order by name) as varchar(500))
,ID
,parent_id
,Lvl=1
,name
From #f_all
Where IsNull(#Top,-1) = case when #Top is null then isnull(parent_id,-1) else ID end
Union All
Select Seq = cast(concat(p.Seq,'.',1000+Row_Number() over (Order by r.name)) as varchar(500))
,r.ID
,r.parent_id
,p.Lvl+1
,r.name
From #f_all r
Join cteP p on r.parent_id = p.ID)
,cteR1 as (Select *,R1=Row_Number() over (Order By Seq) From cteP)
,cteR2 as (Select A.Seq,A.ID,R2=Max(B.R1) From cteR1 A Join cteR1 B on (B.Seq like A.Seq+'%') Group By A.Seq,A.ID )
Select Distinct
A.R1
,B.R2
,A.ID
,A.parent_id
,A.Lvl
,name = Replicate(#Nest,A.Lvl-1) + A.name
From cteR1 A
Join cteR2 B on A.ID=B.ID
Join (Select R1 From cteR1 where IIF(#Filter='',1,0)+CharIndex(concat(',',ID,','),concat(',',#Filter+','))>0) F on F.R1 between A.R1 and B.R2
Order By A.R1
Returns (#Top=null and #Filter='4,6')
Return Full Hier (#Top=null and #Filter='')
Returns Just a portion (#Top=2 and #Filter='')
The problem for me was that i didn't know how cte recursion works. Now i know how it works line by line: Recursive Queries Using Common Table Expressions.
Code below returns all hierarchy by children nodes:
;with tree as(
select id, parent_id, name, level from f_all fa
inner join #2nd_table_cildren_id c on c.id = fa.id
union all
select f.id, f.parent_id, f.name, f.level from f_all f
inner join tree t on f.id = t.parent_id and f.id <> f.parent_id
)
select distinct *
from tree
OPTION (Maxrecursion 0)
I'm new to SQL and I'm trying to rewrite this query so that it uses a join instead of a union
DECLARE #user VARCHAR(255) = 'jSmith'
DECLARE #dept VARCHAR(255) = 'produce'
SELECT DISTINCT A.*
FROM goals A
INNER JOIN managers B ON B.name = #user
WHERE #user IN (A.userName,A.managerUserName)
AND dept = #dept
AND yr = '2016'
UNION
SELECT DISTINCT A.*
FROM goals A
INNER JOIN managers C ON C.name = #user
INNER JOIN committedGoals B ON A.goalID = B.goalID
WHERE dept LIKE #dept + '%'
AND yr = '2016'
This is not exactly the same because you've restricted the second part of the query to records that contain a record in committedGoals, but if you always have a record, then this might work for you:
SELECT g.*
FROM goals g
LEFT JOIN managers m
ON g.managerUserName=m.name
WHERE dept LIKE #dept + '%'
AND yr='2016'
AND (g.managerUserName=#user OR m.name=#user)

I want the CantSocias column takes the most value of the Ciclo column, but not working
That stored procedure that you have posted up is way too large and blocky to even try to interpret and understand. So I will go off of your last sentence:
I want the CantSocias column takes the most value of the Ciclo column,
but not working
Basically if you want to set a specific column to that, you can do something like this:
update YourTable
set CantSocias =
(
select max(Ciclo)
from YourOtherTable
)
-- here is where you can put a conditional WHERE clause
You may need to create a sub query to get the most value of Ciclo and join back to your query.
An example of what I mean is here:
create table #Product
(
ID int,
ProductName varchar(20)
)
insert into #Product(ID, ProductName)
select 1,'ProductOne'
union
select 2,'ProductTwo'
create table #ProductSale
(
ProductID int,
Number int,
SalesRegion varchar(20)
)
insert into #ProductSale(ProductID,Number,SalesRegion)
select 1,1500,'North'
union
select 1, 1200, 'South'
union
select 2,2500,'North'
union
select 2, 3200, 'South'
--select product sales region with the most sales
select * from #Product p
select ProductId, Max(Number) as Bestsale from #ProductSale ps group by ProductID
--combining
select
p.ID,
p.ProductName,
tp.Bestsale,
ps.SalesRegion
from
#Product p
inner join
(select ProductId, Max(Number) as Bestsale from #ProductSale ps group by ProductID) as tp on p.ID = tp.ProductID
inner join
#ProductSale ps on p.ID = ps.ProductID and tp.Bestsale = ps.Number
