T-SQL (SS2K8) :: Tree View Hierarchy Query
Feb 25, 2015ID ParentiD IsAutoCalculate Level
1 0 1 0
2 1 0 1
3 1 0 1
4 1 0 1
5 2 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

Hierarchy In Sql Server
Dec 5, 2007Hello ,
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
MS SQL Server Tree Structure
Sep 11, 2007Can anyone please help me? I need to create a tree structure of my company's database server. I need to include all the tables and their description in a tree structure. The output can be in any format. Is there some tool in the MSSql that will do this for me, so I don't have to write it out manualy?? Thank you very much for any ideas!!

Decision Tree In MS SQL Server
Jun 28, 2007Hi,
Can we represent the Decision Tree in a programatically way in an .NET application? I understand that the outcome of a Decision Tree model can be integrated into an .NET application but not sure if we can also visualize it. Does MS SQL Server support any API to render such a tree?
Thanks a lot!
Recursive/Tree Queries In SQL Server.
Feb 18, 1999Dear fellows,
Can anybody tell me how can i apply recusive/Tree query using select
statement.
For example I've a table structure for an Organization as follows:
TableName: Employee_tbl
Fields: emp_id, emp_name, supervisor_id
emp_id emp_name supervisor_id
---------- --------------- -------------------
101 ZAFIAN
102 BRUNNER 101
108 CALLAHAN 102
105 RUSSO 102
110 SIM 102
103 DUELL 101
and so on
1. How can I get the above records in Hirarchical format starting from top
or from anywhere else in the hierarchy?
In Oracle it can be done as follows:
SELECT emp_id,emp_name,supervisor_id
FROM employee_tbl
CONNECT BY supervisor_id = PRIOR emp_id
START WITH supervisor_id is null;
Please reply me at the following address if possible:

SQL Server 2012 :: Traversing Down A Tree
Feb 9, 2015I'm working with a development bug database where if someone puts in a bug number, they want to get the parent bug. No problem.
SET @cur_parent = (SELECTdupeof_key
FROMqds.dbo.Dimduplicates d
WHEREd.dupe_key = @checkbug
ANDd.end_ts IS NULL)
WHILE @cur_parent IS NOT NULL
[Code] ...
However, now they want to be able to do the same thing in reverse. Put in a bug and determine how many bugs are duplicates (either directly - children, or indirectly - grandchildren/great-grandchildren, etc.).
The majority of bugs go no more than three generations deep but there are some that go much deeper so I need to have something where I can loop through each potential generation and get the number of bugs associated with it.
Example.
Parent Bug Child Grandchild GGChild
1 2 3 4
1 5
1 28 32
1 40 41 42
1 50
1 60
1 65 70
If I put in bug 1 I should be able to get a count of 13 associated duplicate bugs. Additionally, they want to be able to get a list of the bugs that are associated with that parent.
If there were a set number of levels, self-joining would work to create a generational matrix. However, as there is no limit on how deep the generations can go, I need something dynamic to traverse the tree and generate the list of bugs/count of bugs.
It was easy going up the tree because there was a strict one-to-one relationship between child and parent.
Sql Server 2005 And Tree Structures
Mar 9, 2007I am trying to traverse a tree structure like below,
1 Pets
--1.1 Cat
----1.1.1 Persian
----1.1.2 Bengal
--1.2 Dog
----1.2.1 Poodle
2 etc
I would like to be able to search by a keyword, i.e. Poodle, or the reference number, i.e. 1.2.1. I would prefer to do this all through a stored procedure if possible, it seems recursion is the way to go as the number of levels may increase in the future but i'm completely new to this. From what i've seen so far I would need a table structure with a parentID,NodeID,Name field and Primary key.
i.e,
ID...Name......Parent.....NodeID
1....Pets.........0............1
2....Cat..........1............1
3....Dog..........1............1
4....Persian.....2............1
5....Bengal......2............2
6....Poodle......3............1
etc
i've heard that SQL SERVER 2005 provides recursion through CTE, is this the recommended way/only way to achieve this?
Any tips on where to start would be really appreciated.

View 2 Replies View RelatedSQL Server 2012 :: Better Way To Query A Hierarchy Table?
Jan 21, 2015I 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)),

SQL Server 2008 :: Clone Hierarchy To Another Table
Apr 4, 2015I have a table "t_prod_cat" which contains hierarchical data which is used in production to present data.
CREATE TABLE [dbo].[t_prod_cat](
[cat_node_id] [bigint] IDENTITY(1,1) NOT NULL,
[advertiser_id] [bigint] NOT NULL,
[cat_hid] [hierarchyid] NULL,
[level] AS ([cat_hid].[GetLevel]()) PERSISTED,

)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
In order not to impact the production website during the time an advertiser is editing (the editing might take much time and also mainly because at any time during the editing, the advertiser could cancel all the changes he did), I was thinking of transferring all the data linked to that advertiser to another table and let the advertiser apply any modifications up to the moment he will commit the changes.
Therefore, I would like to "CLONE" the hierarchy related to a certain advertiser_id to another table "t_prod_cat_work"
CREATE TABLE [dbo].[t_prod_cat_work](
[temp_cat_node_id] [bigint] NOT NULL,
[temp_cat_hid] [hierarchyid] NOT NULL,
[advertiser_id] [bigint] NOT NULL
) ON [PRIMARY]
What can be the easiest way to clone all the hierarchical data (multi-levels) from 't_prod_cat' to 't_prod_cat_work' for a certain advertiser_id ?

Possible To Speed Up The Decision Tree By Clustering The Server 2003
Aug 24, 2007Dear All,
I have a dataminig programming that need to run for days. Is it possibile to speed up the training process by clustering several server by Windows 2003 clustering services? Is it actually that clustering 2 QUAD core computer is almost giving comparable performance as the sum of the speed of two (There must be some overhead, I know). I am actually familiary with the use of clustering. Is it just for making the server farm more reliable or it will collaborate and speeed up the whole training process?
If it is, is there any limit on the number of cluster is in the cluster. What version of Windows and SQL Server do I need to achieve speed up of data mining training process?
Thanks and regards

Dear All
The problem is I am going to predict the production for different category of product.
attributes are
year - key
A production - predict only
B production -predict only
C production -predict only
And in the SQL it is impossible to to give input and predict (I am not sure whether that is a error or not).
And in the decision tree
for the
Product A - get as product A >=12324
Product B year > 2000
Product C product C >=35454
I want to know why the label is changing time to time.
Please help me on this. Thank you

SQL Server 2008 :: Converting Adjacency List To Hierarchy Table
Feb 10, 2015I have been trying to convert an existing table that used adjacency list model (parentid,childid) to a table that use hierarchy Id type. So early on, I notice my original data does contains multiple roots. So I took a step to create dummy nodes to ensure all nodes fall into a single root structure. Another important fact is that each child node can have multiple parents.
My original source table contains 22461 records, when running the query below step 2 produces explosive number of records around 175,000+ records. I spent hours study the result and couldn't understand what actually causing this, I ran it against small set of test data I didn't seem the issue caused by child with multiple parents.
select * from SourceTable -- produces 22461 records
--step 1: first, get row number of child records in each parent
SELECT ChildID,ParentID, ROW_NUMBER() OVER (PARTITION BY PARENTID ORDER BY PARENTID) as Num

SQL Server 2012 :: Finding Lowest Level Descendants In Hierarchy
Mar 11, 2015I've got a fairly large hierarchy table and I'm trying to put together a query to find the lowest level descendants of the hierarchy. I think there must be some way to use the "Breadth-first" approach that's stated in the MSDN technet sites about SQL Server HierarchyID but i'm not sure how to write the necessary T-SQL to traverse that. I know I can get all the descendants of a parent node like this
SELECT *
FROM AdventureWorks2012.HumanResources.Employee
WHERE OrganizationNode.IsDescendantOf(@ParentNode) = 1
However, this query returns all levels for that parent's branch. If I just wanted list of employees that were at the lowest level of the branch(es) for this parent node, how would I do this?

May 20, 2004Dear all,
I would like to know how to create a single level hierachy structure in SQL.
Example, I have a single parent record in table A that may later on spawn one or child record in table B that relates back to the parent. It only needs a single level.
that means, one to many.

Tree
Jan 2, 2008I have two tables.
table1 has 3 fields a , b and c. field "a" is a primary key.
table2 has 2 fields x and y. Fields x and y are nothing but the value of "a". Also, y is the child of x.
Therefore, x and y can never have same value. It means value of "a" either be child or parent.
But there is possibility that parent has no child.
Now, i wanted to write Select/Insert query for parent, b , c and child.
This tree is no a binary tree but N-Ary Tree.
Thanks,

HIERARCHY HELP! PLEASE?
Feb 26, 2008I 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

Tree-walking In T-SQL
May 18, 2007Hi,
I'm having a major brain-failure moment here.
Using T-SQL I want to be able to get all of the leaf nodes (e.g. nodes at the furthest end of a tree from the root) in a hierarchical relationship where the table structure is such NodeID|ParentID|NodeName.
Basically if I had the following tree structure:
Root
Child1
Grandchild1
Child2
Grandchild2
I want to get all of the Grandchild nodes. Number of levels will vary and I haven't got any kind of HasChilds column.
I know this is possible because I remember having done it on a course years ago but I can't for the life of me figure it out on this sunny Friday afternoon. I know it's going to involve either recursion, a while loop or cursors but my mind is currently jelly. Can anyone help?
