Help With A Hierarchy Query Or Procedure
Mar 8, 2007
I have a table with a parent, child, and grandchild relationship. Can anyone help me with a query that will return the child and grandchild of a parent?
Heres my table:
id pid name
--------------------------------
1 0 UntID
2 0 Vin Number
3 0 Make
4 3 Model
5 4 Model Number
6 0 Model Year
7 0 Vehicle Type
8 0 Odometer Miles
When I select 3 as the id I need these results:

Thanks for any help!

I am wanting to run a SQL statement whereby i return the ID of any employee's Director.
The database for employees has a reports to field which enables me to see the hierarchy of managers above any employee.
There is also a IsDirector flag that indicates a director.
So essentially i want to run sql that would return the first instance of a director in the hierarchy above any employee.
eg if A reports to B and B reports to C (who is a director) then it returns C.
I basically want the script to run until a director is found.
how would i do this?

I have a table named 'DepartmentItem' which is designed with hierarchy structure. The column 'ParentId' from table DepartmentItem indicates parent-child relationship and department root among records. I have written and run a user-defined function I use recursive approach, but the function runs slowly.
My question: is there a better way to query that hierarchy table instead of using recursive?
** The current user-defined function that is written using recursive:
CREATE FUNCTION dbo.fnGetDepartmentTree
(
@departmentItemId int
)
RETURNS TABLE
AS
RETURN
with DepartmentItemTree(DepartmentItemId , DepartmentItemTypeId , ParentId, ItemOrder, Level)
[code].....
** And definition of table 'DepartmentItem' :
DepartmentItemId int IDENTITY(1,1) NOT NULL,
ParentId int NULL, -- Each department root starts when this column is NULL or the current row is department root. If it is not NULL then the current row has ParentId whose record has DepartmentItemId = ParentId of the current row (see more below)
IsActive bit NOT NULL DEFAULT ((1)),
[Code] .....

ID ParentiD IsAutoCalculate Level
1 0 1 0
2 1 0 1
3 1 0 1
4 1 0 1
5 2 0 2
6 2 0 2
7 3 0 2
8 4 0 2
9 0 1 0
10 9 0 1
11 0 1 0
12 11 1 1
13 12 0 2
The above table shows a parent child relationship with the hierarchy shown in column level. for each parent (IDs 1, 9, 11), I want the first child level where the column IsAutoCalculate = 0
so for parent Id 1, the rows to be returned is of level 1 as that is the first child row of this parent with IsAutoCalculate = 0. The rows with level 2 should not be returned
For parent id 3, the rows to be returned will be with level 2 as this is the first child row of this parent with IsAutoCalculate = 0

I am in the process of develping a MSRS report using an MSAS 2005 OLAP cube as my data source. In the MSRS Query Builder, I am using an MDX query which successfully executes in Management Studio. Something like the following:
SELECT
NON EMPTY { [Measures].[Fact Count] }
ON COLUMNS,
NON EMPTY{ ( [Dim Attribute].[Hierarchy Not Visible].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME
ON ROWS
FROM [MyCube]
CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
The twist is that the AttributeHierarchyVisible property of the [Dim Attribute].[Hierarchy Not Visible] is set to False.
As mentioned previously, the query successfully executes in Management Studio. However when it is executed in the MSRS Query Builder, the following error message is displayed:
The query cannot be prepared: The query must have at least one axis. The first axis of the query should not have multiple hierarchies, nor should it reference any dimension other than the Measures dimension..
Parameter name: mdx (MDXQueryGenerator)
Is there a way to successfully query dimension attributes whose hierarchies are not visible?
Thanks.

For some reason, I run a stored procedure in Query Analyzer and it works fine. When I run the very same procedure in MS access by clicking on its link I have to run it twice. The first run gives me the message that the stored procedure ran correctly but returned no records. The second run gives me the correct number of records but I have to run it twice. I am running month-to-month data. The first run is Jan thru March. Jan and Feb have no records so I run three months on the first set. The ensuing runs are individual months from April onward. The output is correct but any ideas on why I have to do it twice in Access? I am a bit new to stored procedures but my supervisor assures me that it should be exactly the same.

When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

I executed the code successfully and I got a box which asked for "Enter the query string".
I typed in the following: EXEC dbo.SalesByCategory @Seafood. I got the following box: Query attempt failed. Must declare the scalar variable "@Seafood". I am learning how to enter the string for the "SQL query programed in the subQuery_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnQuery.Click" (see the code statements listed above). Please help and tell me what I missed and what I should put into the query string to get the information of the "Seafood" category out.
Thanks in advance,

I have an Interesting situation that I'm hoping some of you experts can help me with basically I have the following hierarchy:
Net Profit
.....Gross Profit
..........Revenue
..........Direct Costs
.....Indirect Expense
Now, I have another hierarchy - separate from the above - that I need to assimilate to the hierarchy above - Example:
Expenses
.....Node a
..........Child a (Indirect Expense Type)
.....Child b (Direct Cost type)
Net Sales Adjustments
.....Child a (Revenue type)
.....Child b (Revenue type)
Depending on the type, the top most node needs to be assigned to the appropriate node in the initial hierarcy, like this:
Net Profit
....Gross Profit
........Revenue
................Net Sales Adjustments
....................Child a (Revenue type)
....................Child b (Revenue type)
........Direct Costs
...........Expenses
.................Child b (Direct Cost type)
........Indirect Expense
............Expenses
.................Node a
.....................Child a (Indirect Expense Type)
Now, I've been able to figure out how to assign the top most node and leafs if all the children have the same type (using the expan stored proc listed in the books online), but my question is on this portion:
Expenses
.....Node a
...........Child a (Indirect Expense Type)
.....Child b (Direct Cost type)
Basically, the answer is to work backwards - if a child has a type that is different than the other children, a copy of the hierarch (up to the child) needs to be made and assigned to the appropriate initial node.
I've tried modifying the expand stored proc to give me the lineage of the child and see if there's a way I can copy the node and place it appropriately - I'm brainfried at this point, and I'm hoping that someone outthere can point me in the right direction.
Thanks in advance for your time

Hi to All!
Is there a perfect method to implement a hierarchy structure with different types as a table in Sql server 2005? Currently I am thinking of this way:
[Node | ParentId | ParentType | ChildId | ChildType]
But there is this nagging little voice saying it can be better
Cheers!

Hi, I'm trying to figure out how to write I SP on the following table that will produce the results show at the bottom. My main problem is the sorting, is there a way I loop through the records in TSQL and ORDER BY SortSort where the ParentID's are the same?
Thank you.
Table example

Hi all,
Ive got a bit of a problem,
I have two tables:
CATEGORY
id
name
parent_CATEGORY_id
RECORD
id
CATEGORY_id
Stock_Held_Number
ps. Ive stripped out any non relevant fields
I also have the following query (again ive stripped out the non-relevant fields)
SELECT TOP (100) PERCENT SUM(dbo.RECORD.Stock_Held_Number) AS TotalStock, CATEGORY.Name AS FundName
FROM CATEGORY
LEFT OUTER JOIN dbo.RECORD ON CATEGORY.ID = dbo.RECORD.CATEGORY_id
GROUP BY CATEGORY.Name, RECORD.Stock_Held_Number
At the moment its grouping all the CATEGORIES and giving me a sum total for each which is great.
The problem I have is the CATEGORY table, there is an optional join to parent CATEGORY records on the table.
What Im trying to do is to provide a fully ordered result within the CATEGORIES and I don't have a clue.
For example:
The CATEGORY table has the following values
ID Name Parent_Category_id
1 Pens
2 Animals
3 Rocks
4 Horses 2
5 Dogs 2
When I currently run the query I get:
Name TotalStock
Pens 20
Animals 30
Rocks 40
Horses 50
Dogs 60
It's technically correct because I don't want the parent to calculate the total value of the children
What Im really trying to do is order them within the hierarchy though and indent (if possible) the result so I would get
Name TotalStock
Animals 30
---Dogs 60
---Horses 50
Pens 20
Rocks 40
Does anybody have any pointers as to how I can achieve this.
Many thanks
Mike

Greetings!I could really use some suggestions on how to improve on thefollowing, it at all possible:Table 'Customer'---------------------ID GUID PK....Table 'Facility'-----------------ID GUID PKCustomerID GUID FK (FK to Customer GUID)....Table 'Rate'----------------ID PKOwnerID GUID Nullable FK (FK to Customer, Facility GUID PK)OwnerLevel INT Contraint 1-3<Rate Data>Table 'Rate' is a sparse hierarchy of data. There are 3 possiblelevels in the hierarchy as follows:OwnerID <NULL>OwnerLevel 1This indicates Global rate data.OwnerID <Customer.ID>OwnerLevel 2This indicates Customer-specific rate data.OwnerID <Facility.ID>OwnerLevel 3This indicates Facility-specific rate data.Now, a given Customer need not have an entry in the Rate table. If aCustomer does not have an entry, it is supposed to 'inherit' Globalrate data. A given Facility need not have an entry in the Rate table.If a Facility does not have an entry, it is supposed to inheritCustomer-specific rate data, and in the absence of an entry for theFacility's parent Customer, it is supposed to inherit Global ratedata.The challenge is that I want to write a view to give me back theappropriate rate record for Customer and Facility.

Hi everybody,
I've been reading the book MCITP Self-Paced Training Kit (Exam 70-441): Designing Database Solutions by Using Microsoft SQL Server(TM) 2005 (Self-Paced Training Kits) as a part of my preparation for exam 70-441
The book is really clear, and I could understand everything easily because I've some experience as a database developer.
Until now, there's only one thing that I didn't fully understand:
On pages 53 and 54, it mentions a type of hierarchy called: a graph hierarchy, and it gives a small example made the things even more complicated
I've many books about database design theories, but they don't use the term (graph hierarchy) any where...
So, I appreciate if you can point me to an online resource or a book that discusses this term thorougly.
Thank you

Hello experts,
Last time I worked with SSAS and build a Cube. Because I€™m now very happy with the front-end excel 2003 or excel 2007 I thought I build my own Report with SSRS.
Now there is something I don€™t understand:
I build a Hierarchy in SSAS that a want to use in SSRS. Is there a chance to use it without any features? Have I to use parameters or something another?
In my opinion it makes any sense to build a hierarchy new, because it€™s already exists in SSAS.
Have a nice day
Alex

Hello ,
I'm facing a complicated problem and I don't think that the solution will be an easy one.
I have an SQL statement in Oracle which I need to translate it in Sql Server 2005.
select lpad(' ',5*(orderid)) || to_char(descr) as menui
from <table _name>
where MENU_ITEM not in ('test1','test2','test3') and item_parent not in ('test4,'test5,'test6')
start with <item_parent='item_parent' >
connect by prior <menu_item = item_parent and menu_name='something'; > ?(condition)
Somewhere I have read that SQL server does not support Hierarchical Sql statements. Is this true ? How am I going to do that ?
Any help will be appreciated.
Thank you

How can I get the data from a table that stores hierarchical information keeping the right order and hierarchy levels?
I also need to specify a first level....let me explain.
Table: Sites
Id (PK)
Title
Url
ParentId
If I have something like this:
1 | Test | http://localhost | NULL
2 | Sub-Test | http://localhost/subtest | 1
3 | SecondItem | http://anotherServer | NULL
4 | ChildOfSub-Test | http://localhost/subtest/child | 2
And I specify that I want all child items below the Id 2, it must return:
Id | Title | Url | ParentId | Depth
2 | Sub-Test | http://localhost/subtest | 1 | 0
4 | ChildOfSub-Test | http://localhost/subtest/child | 2 | 1
How can I do this? I've saw some examples with CTEs, but they always return all of the items.

Hi people
In have a query over two tables, and the ouptut is:
RowID | SubMarcaID | MarcaID | ProductoID
1 | 1 | 1 | 1
2 | 1 | 1 | 2
3 | 1 | 1 | NULL
4 | 3 | 1 | 3
5 | 3 | 1 | NULL
(SubMarcaID and MarcaID are the KEYS from SUBMARCA, and ProductoID is the key from PRODUCTO. Also SubMarcaID and MarcaID are foreing keys on PRODUCTO)
Now, I need a ParentRowID based on SubMarcaID and MarcaID, like a hierarchy
RowID | SubMarcaID | MarcaID | ProductoID | ParentRowID
1 | 1 | 1 | 1 | 3
2 | 1 | 1 | 2 | 3
3 | 1 | 1 | NULL | 0
4 | 3 | 1 | 3 | 5
5 | 3 | 1 | NULL | 0
How can I do this?
Code Block
SELECT ROW_NUMBER() OVER (ORDER BY PRODUCTO.MarcaID, PRODUCTO.SubMarcaID) AS RowID,
PRODUCTO.SubMarcaID,
PRODUCTO.MarcaID,
PRODUCTO.ProductoID
FROM PRODUCTO, SGP_SUBMARCA
WHERE PRODUCTO.SubMarcaID = SUBMARCA.SubMarcaID
AND PRODUCTO.MarcaID = SUBMARCA.MarcaID
GROUP
BY PRODUCTO.SubMarcaID,
PRODUCTO.MarcaID,
PRODUCTO.ProductoID
WITH
ROLLUP
HAVING (
GROUPING(PRODUCTO.ProductoID) = 1
AND GROUPING(PRODUCTO.SubMarcaID) = 0
AND GROUPING(PRODUCTO.MarcaID) = 0
)
OR (
GROUPING(PRODUCTO.SubMarcaID) = 0
AND GROUPING(PRODUCTO.MarcaID) = 0
AND GROUPING(PRODUCTO.ProductoID) = 0
)

For a short time I have considered how to get the hierarchy in a self-linked table, incidentally I have found an article about ‘Recursive CTEs’ in ‘SQL Server Books Online’, where an example is very impressive and arouses me to find a way to get the ancestors or descendants of a given node in a self-linked (self-referenced) table.
And now I want to share this method to anyone who has the same problem to resolve or someone like me who has addiction in SQL.
First of all we have to create a table for the following functions and build some test data. The statemens look like:
create table ST_CATEGORY(
CATEGORYID uniqueidentifier not null default NEWID(),
PARENTID uniqueidentifier,
[NAME] varchar(128),
COMMENT varchar(4096),
CONSTRAINT PK_ST_CATEGORY primary key (CATEGORYID)
)
go
insert into ST_CATEGORY(CATEGORYID, PARENTID, [NAME], COMMENT)
values(@rootoid, NULL, 'ROOT', 'ROOT NODE')
insert into ST_CATEGORY(CATEGORYID, PARENTID, [NAME], COMMENT)
values(NEWID(), @rootoid, 'Business Application', 'group for all business applications')
declare @techoid uniqueidentifier
set @techoid = NEWID()
insert into ST_CATEGORY(CATEGORYID, PARENTID, [NAME], COMMENT)
values(@techoid, @rootoid, 'Tech101', 'technical tips')
insert into ST_CATEGORY(CATEGORYID, PARENTID, [NAME], COMMENT)
values(NEWID(), @techoid, 'C#', 'C# tips')
go
Now that the test table and data are prepared, we can get ancestors or descendants through the following four stored procedures of a given category.
CREATE PROCEDURE spGetAncestor
@categoryID uniqueidentifier
AS
BEGIN
-- find parents/ancestor
WITH Ancestor( CATEGORYID ) AS
(
SELECT PARENTID
FROM ST_CATEGORY
WHERE CATEGORYID = @categoryID
UNION ALL
SELECT PARENTID
FROM Ancestor, ST_CATEGORY
WHERE Ancestor.CATEGORYID = ST_CATEGORY.CATEGORYID
)
SELECT * FROM Ancestor
END
GO
CREATE PROCEDURE spGetSelfAndAncestor
@categoryID uniqueidentifier
AS
BEGIN
-- find self and parents/ancestor
WITH SelfAndAncestor( CATEGORYID ) AS
(
SELECT CATEGORYID
FROM ST_CATEGORY
WHERE CATEGORYID = @categoryID
UNION ALL
SELECT PARENTID
FROM SelfAndAncestor, ST_CATEGORY
WHERE SelfAndAncestor.CATEGORYID = ST_CATEGORY.CATEGORYID
)
SELECT * FROM SelfAndAncestor
END
GO
CREATE PROCEDURE spGetDescendant
@categoryID uniqueidentifier
AS
BEGIN
-- find children/descendant
WITH Descendant( CATEGORYID ) AS
(
SELECT CATEGORYID
FROM ST_CATEGORY
WHERE PARENTID = @categoryID
UNION ALL
SELECT ST_CATEGORY.CATEGORYID
FROM Descendant, ST_CATEGORY
WHERE Descendant.CATEGORYID = ST_CATEGORY.PARENTID
)
SELECT * FROM Descendant
END
GO
CREATE PROCEDURE spGetSelfAndDescendant
@categoryID uniqueidentifier
AS
BEGIN
-- find self and children/descendant
WITH SelfAndDescendant( CATEGORYID ) AS
(
SELECT CATEGORYID
FROM ST_CATEGORY
WHERE CATEGORYID = @categoryID
UNION ALL
SELECT ST_CATEGORY.CATEGORYID
FROM SelfAndDescendant, ST_CATEGORY
WHERE SelfAndDescendant.CATEGORYID = ST_CATEGORY.PARENTID
)
SELECT * FROM SelfAndDescendant
END
GO

Ok first I am still very new to SQL so I really do not understand quite a bit (SP's, Sub Query's,CTE, etc..). I also went through the SQLTeam article on trees and hierachies but only confused myself even more.
I will try my best to put all the information that I know of (in the shortest way that I know).....sorry I know this is long :(
SQLExpress2005
SQL Server Management Studio Express
Two Tables
PartMaster
PRTNUM_01.......varchar(30) ////Part Number

I have gotten Close but no cigar with the following:
SELECT ps.PARPRT_02,
ps.COMPRT_02,
pm.PMDES1_01 + ' ' + pm.PMDES2_01 as Description,
ISNULL(ps2.PARPRT_02, 'n.a.') AS [Sub Component],
ISNULL(ps2.COMPRT_02, 'n.a.') AS [Part Number of Sub],
ps.EFFDTE_02, ps.QTYPER_02
FROM ProductStructure ps
INNER JOIN
(SELECT COMPRT_02, MAX(EFFDTE_02) AS EFFDTE_02
FROM ProductStructure
WHERE (PARPRT_02 = '4235')
GROUP BY PARPRT_02, COMPRT_02) AS p3
ON ps.COMPRT_02 = p3.COMPRT_02 AND ps.EFFDTE_02 = p3.EFFDTE_02
Inner Join PartMaster AS pm On pm.PRTNUM_01 = ps.COMPRT_02
LEFT JOIN ProductStructure ps2
ON ps2.PARPRT_02 = ps.COMPRT_02
WHERE ps.PARPRT_02 = '4235'
ORDER BY
ps.PARPRT_02, ps.COMPRT_02
Which is returning:

4235|IPC4235-03|Chassis Parts|IPC4235-03|100773|2008-05-20|0
Line 1 - fine / Line 2 - fine / Line three (need to add description Part number of Sub)(need to keep original) / Line 4 and 5 same as line 3 / Line 6 and Line 7 should not show because the later date has a QTY of zero / Line 9 should not show because date is zero.
I once again appologize for the length and details on this , but this is has been driving me nutts. ANY help will be appreciated.
Thanks
