Selecting All Items In A Recursive Relationship
Feb 21, 2007
Hello
I'm having trouble writing a query that references a join to a table with a recursive relationship in a SQL Server 2005 database.
I have a list of products in Table1.
Each product belongs to a Category.
Categories are stored in Table2 which has a self-referencing relationship that forms a hierarchical list of categories and sub-categories.
Like so...
||-ID-||-Name-||-Parent-||
||1 ||Cat1-----||Null-----||
||2 ||Cat2-----||Null-----||
||3 ||Cat3-----||1-------||
||4 ||Cat4-----||1-------||
||5 ||Cat5-----||2-------||
||6 ||Cat6-----||2-------||
||7 ||Cat7-----||3-------||
What I'm trying to do is write a sproc that will pull down all products that belong to a particular category or any of it's sub-categories.
I managed to write a sproc that could handle two levels of category by using union to join two queries together but I don't know how to handle an n-tier hierarchical structure.
Can you point me in the right direction?
Many Thanks

Hi all,
Im really confused and need some help please from some of you clever people.
I know the basics of SQL but Ive no idea how to write a query to do this.
Basically, we have two tables, the first containing a list of people and the second containing two relationships to the person table. The first is the parent relationship and the second the child relationship. Each person may be related to one or more other people (e.g. father, son, brother, sister etc.). If you can imagine we have a few hundred people in the person going back a couple of hundred years.
Now Ive set the scene Im really trying to create a query that can navigate all the relationships from a set point (Person).
Ultimately I would like to (given a PersonID, navigate the full PERSON_ASSOCIATION table to find:
a. All people below the PersonID (if there are any)
b. All people above the PersonID (if there are any)
For example, in the data below there is somebody called John Smith.
Going down the PERSON_ASSOCIATION table I would like to show:
John Smith has a brother called Andrew Jones who has a brother-in-law called Stephen Barnes
John Smith has a wife called Jane Wallace
John Smith has a daughter called Mary Joseph
What I am going round in circles on is the multiple relatationships, e.g. A is related to B who in turn is related to D who in turn is related to E therefore A is related to E.
PERSON
ID NAME
1 John Smith
2 Andrew Jones
3 Jane Wallace
4 Steven Barnes
5 Mary Joseph
98 Me
99 Joanne
PERSON_ASSOCIATION
ID PARENT_PERSON_ID CHILD_PERSON_ID RELATIONSHIP
1 1 2 Brother
2 1 3 Wife
3 1 5 Daughter
4 2 4 Brother-In-Law
5 98 1 Father
6 98 99 Husband
Can somebody please point me in the right direction by explaining how I can write some SQL that will navigate (and iterate through) all the PERSON and PERSON_ASSOCIATION tables.
Im sure there must be a straight forward way of doing this.
One final thing, if it helps, Im hoping to eventually end up with a stored procedure which I can basically pass in a PERSON_ID and it returns a list of all the relationships from that person.
MANY BIG thanks in advance
Im really sorry but it is driving me crazy

I am using tables with recursive relationships extensively. For example the table tbComponent has a primary key called Co_ID and a foreign key called Co_Co_ID which references the field Co_ID. This allows a component to have unlimited child components, and each child component can have an unlimited number of tiers of children. I have a few question for which I have seen no documentation on.
1. How can I create a view or a SP that will return a component record and all of its children and children's children records down to the last/lowest child record?
2. I need to be able to do a search in this table. Example:
Table: tbComponent
Columns: Co_ID Integer
Co_Co_ID Integer
Co_Name Text
Co_Attribute Text
Co_Category Text
Note: the data for Co_Category comes from a lookup table with also has a recursive relationship to itself where a category can have an unlimited number of tiers of children categories.
A typical group of records could be something like this:
Co_ID Co_Co_ID Co_Name Co_Attribute Co_Category
1 1 Car Blue Ford
2 1 Body Steel Parts
3 2 Door Front Parts
4 3 Invoice April 1 1999 Accounting
Ok, say there is over a million records in this table. Say I want to query this table and return all of the invoices for cars between March 1 1999 and May 1 1999. Say for example that there are less records where Co_Name has a value of Car then there are records with a value of Invoice, so logically I would set some kind of criteria to limit only invoices with where Co_Name = "Car". That's easy, I can return a result set of all the records Where Co_Name = "Car" and I can hold these in a view or a temp table. Now I need to query this View or temp table and see if it has any children records records Where Co_Name = "Invoice" . The problem is that the Invoice child could be a child record directly under the "Car" record, or 10 levels of children records down. The logic for this would be:
If Co_Name = "Car" Then Select * Where Co_Co_ID = 1, then take all of those record's values in Co_ID and run another statement Where Co_Co_ID = X and so on until there are no more children to search. If any of those records have a value of Invoice in Co_Name then return them.
Please don't give any speeches on Normal Relationship Database design suggesting a typical design using something like a Car table, a parts table, and a invoice table. I used the example above to demonstrate the dynamics of doing a search on a recursive relationship. I understand relationship theory and a recursive relationship is what we need to use in our situation.
Thanks for any and all input!

I am fairly new to SQL and I am currently trying to createa SQL table (using Microsoft SQL) that has a recursiverelationship, let me try to explain:I have a piece of Data let's call it "Item" wich may again contain onemore "Items". Now how would I design a set of SQL Tables that arecapable of storing this information?I tried the following two approaches:1.) create a Table "Item" with Column "ItemID" as primary key, somecolums for the Data an Item can store and a Column "ParentItemID". Iset a foreign key for ParentItemID wich links to the primarykey"ItemID" of the same table.2.) create separate Table "Item_ParentItem" that storesItemID-ParentItemID-pairs. Each column has a foreign key linked toprimary key of the "Item" Column "ItemID".In both approaches when I try to delete an Item I get an Exceptionsaying that the DELETE command could not be executed because itviolates a COLUMN REFERENCE constraint. The goal behind these FK_PKrelations is is that when an Item gets deleted, all childItems shouldautomatically be deleted recursively.How is this "standard-problem" usually solved in sql? Or do I inned toimplement the recursive deletion myself using storedprocedures or something ?

Hello,
I have a question about writing an SQL query than can run in Access and/or MS SQL Server.
I have a table with the following fields (amongst others):
City
Store
SalesDollars
There are 10 cities, with each city containing 100+ stores, each with a SalesDollars numeric value.
1) How do I write a SELECT statement that will return the top 50 stores from each city (500 in total) ?
2) How do I create a field that is the ranking of all these stores in descending order by SalesDollars (1-500)?
Thank you in advance for your help!

I am having problem to apply updates into this function below. I triedusing cursor for updates, etc. but no success. Sql server keeps tellingme that I cannot execute insert or update from inside a function and itgives me an option that I could write an extended stored procedure, butI don't have a clue of how to do it. To quickly fix the problem theonly solution left in my case is to convert this recursive functioninto one recursive stored procedure. However, I am facing one problem.How to convert the select command in this piece of code below into an"execute" by passing parameters and calling the sp recursively again.### piece of code ############SELECT @subtotal = dbo.Mkt_GetChildren(uid, @subtotal,@DateStart, @DateEnd)FROM categories WHERE ParentID = @uid######### my function ###########CREATE FUNCTION Mkt_GetChildren(@uid int, @subtotal decimal ,@DateStart datetime, @DateEnd datetime)RETURNS decimalASBEGINIF EXISTS (SELECTuidFROMcategories WHEREParentID = @uid)BEGINDECLARE my_cursor CURSOR FORSELECT uid, classid5 FROM categories WHERE parentid = @uiddeclare @getclassid5 varchar(50), @getuid bigint, @calculate decimalOPEN my_cursorFETCH NEXT FROM my_cursor INTO @getuid, @getclassid5WHILE @@FETCH_STATUS = 0BEGINFETCH NEXT FROM my_cursor INTO @getuid, @getclassid5select @calculate = dbo.Mkt_CalculateTotal(@getclassid5, @DateStart,@DateEnd)SET @subtotal = CONVERT (decimal (19,4),(@subtotal + @calculate))ENDCLOSE my_cursorDEALLOCATE my_cursorSELECT @subtotal = dbo.Mkt_GetChildren(uid, @subtotal,@DateStart, @DateEnd)FROM categories WHERE ParentID = @uidENDRETURN @subtotalENDGORod

I am struggling to come up with a set-based solution for this problem (i.e. that doesn't involve loops/cursors) ..A table contains items (identified by an ItemCode) and the set they belong to (identified by a SetId). Here is some sample data:
SetIdItemCode
1A
1B
24
28
26
310
312
410
[code]....
You can see that there are some sets that have the same members:
- 1 and 10
- 2 and 11
- 7, 8 & 9
What I want to do is identify the sets that have the same members, by giving them the same ID in another column called UniqueSetId.

How can I create a one-to-one relationship in a SQL Server Management Studio Express Relationship diagram?
For example:
I have 2 tables, tbl1 and tbl2.
tbl1 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}
tbl2 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}
tbl1_id {uniqueidentifier} as FK linked to tbl1.id
If I drag and drop the tbl1.id column to tbl2 I end up with a one-to-many relationship. How do I create a one-to-one relationship instead?

I'm having an issue creating a report that can group & sum similar items together (I know in some ways, the requirement doesn't make sense, but it's what the client wants).
I have a table of items (i.e. products). Â In some cases, items can be components of another item (called "Kits"). Â In this scenario, we consider the kit itself, the "parent item" and the components within the kit are called "child items". Â In our Items table, we have a field called "Parent_Item_Id". Â Records for Child Items contain the Item Id of the parent. Â So a sample of my database would be the following:
ItemId | Parent_Item_Id | Name | QuantityAvailable
----------------------------------------
1 | NULL | Kit A | 10
2 | 1 | Item 1 | 2
3 | 1 | Item 2 | 3
4 | NULL | Kit B | 4
5 | 4 | Item 3 | 21
6 | NULL | Item 4 | 100
Item's 2 & 3 are child items of "Kit A", Item 5 is a child item of "Kit B" and Item 6 is just a stand alone item.
So, in my report, the client wants to see the SUM of both the kit & its components in a single line, grouped by the parent item. Â So an example of the report would be the following:
Name | Available Qty
--------------------------
Kit A | 15
Kit B | 25
Item 4 | 100
How I can setup my report to group properly?

I have four tables with relationships as shown. They have a circular relationship and so one of the relationships is forced to be inactive.
  Operation (Commodity, OperationKey)  ==========>Â
Commodity (Commodity)
                     /                                                                       Â
/
                      |                                                                        Â
|
  Advice (OperationKey)      ====== (inactive)=======>
Operation Commmodity (Commodity, OperationKey)
I have the following measure:
Advice No. Commodity:=CALCULATE (
COUNTROWS ( 'Advice' ),
USERELATIONSHIP(Advice[OperationKey],'Operation Commodity'[OperationKey]),
operation
)
However, the userelationship function does not override the active relationship between Operation & Advice and so the measure is limited to Advices directly filtered by the Operation table.
If I delete the relationship between Operation and Advice, then the measure works as expected i.e. Operation indirectly filters Operation Commodity which filters Advice.

I've got a big problem that I'm trying to figure out:
I have an address table out-of-which I am trying to select mailing addresses for companies UNLESS a mailing address doesn't exist; then I want to select the physical addresses for that company. If I get multiple mailing or physical addresses returned I only want the most recently edited out of those.
I don't need this for an individual ID select, I need it applied to every record from the table.
My address table has some columns that look like:
[AddressID] [int]
[LocationID] [int]
[Type] [nvarchar](10)
[Address] [varchar](50)
[City] [varchar](50)
[State] [char](2)
[Zip] [varchar](5)
[AddDate] [datetime]
[EditDate] [datetime]
AddressID is a primary-key non-null column to the address table and the LocationID is a foreign key value from a seperate Companies table.
So there will be multiple addresses to one LocationID, but each address will have it's own AddressID.
How can I do this efficiently with perfomance in mind???
Thank you in advance for any and all replies...

Hello Everyone,
I have a purchase order table that holds say 2 columns. PO and OrgPO. That is Purchase Order # and Original Purchase Order # respectively. Assume i have the following rows in the table.
PO OrgPO
-- ------
po1 NULL
co1 po1
co2 co1
co3 co2
po2 NULL
cpo1 po2
po3 NULL
Now what i would like to report in the output is the PO and along with the lastly generated change order for that po. For eg,
PO LastCO

po1 co3
po2 cpo1
po3 po3
Currently i 'm using function to achieve this effect and i believe this is not the efficient way. I would like to generate this in a much efficient way. Please help me to achieve this.

Hello,
I have the following tables:
Article(articleID,CategoryID,ArticleTitle)
Categories(categoryID,ParentID,CategoryTitle)
I am trying to retrieve the main category ID for a specific article ID.
For example lets say I have this data:
Article:
1, 10 , "some title"
2,10,"some title"
3,11,"some title"
Categories:
1, NULL , "some title"
2, 1, "some title"
10, 2, "some title"
11, 10 , "some title"
In this example I want to know who is the main category of article 3.
The query should return the answer: 1
Thats because:
The article ID 3 is inside category 11.
Parent for category 11 is 10.
Parent for category 10 is 2.
Parent for category 2 is 1
and Parent for category 1 is NULL, which means category 1 has no parents and it is the main category.
Query will return article id, category id, main_category_id, ArticleTitle, CategoryTitle (some union between 2 tables)
Do you have any suggestions for such query?
Thanks all.

Recursive quey to show products with "custom defines fields" related by Classifications, instead of per product Hello, I’m working on a project .. .
I’m desperating due to the
complex (for me and also I think for some others) sql query that I need to

table that holds this mentioned “custom defined fieds� according to the Classifications
table, on where the Products can be found trought the productsClassifications
table.
CustomFields can be defined
and set for the products, trought his Classifications (instead of define a
custom field for each product (that consume a lot of data), I decide to use it as
I explain)
I will to know the properly
SQL QUERY to show a list of products with the ProductsFieldsByClassifications and ProductsFieldsValuesByClassifications:
As example on
a Requested ID_Classification = 16 (Torents/Games/Dreamcast/PAL), the products must be show with the
ProductsFields and Values that has the DBA for the:
·
requested
ID_Classification
o
PAL (ID_Classification: 16)
·
AND all
the Classifications that belongs above (trought ID_ParentClassification) that are :
o
Torrents (ID_Classification:
1) that will show the products values for the “Size�
o
Games (ID_Class..:4) ß this classification has no CustomFields so none from this one.
o
Dreamcast (ID_Class..:14 )
that will show his ID_Classification(14) product field “Levels� value (but not “AllowSave� as not have value for any product)

Hi,
Does anyone know how to do an sql recursion queries?
I believe it involves a view with a union.
I have a User Table and in that table i have a employee_id and a
boss_id. What i'd like to do is to find all employees under a certain
boss.
For example,
Employee_ID Boss_ID
1
2 1
3
4 3
5 2
So if i'd like to know who are under the employee_id = 1 it will return
employee_id 2 and 5 since employee 2 also is the boss of employee_id =
5.
To do that i'd have to have recursion query.
Thanks,

The second trigger must be started by the first one.

delete from templates where id = 2 more than one page (7 pages) are deleted and the second trigger doesn't work (it can only delete one by one in pageitems!)
Is there any option in SQL Server that I forgot or can I use an other methode

Hi,
I have a table with 2 fields in it Circuit_ID and Parent_Circuit_ID and I'd like to pass a stored procedure a circuit_ID and get a resultset back of all Circuit_ID's that are associated with the original.
That means it needs to look at each record and do another search on all circuits that have that parent ID, recursively.
Does anyone have any good ideas on the best way to do this.
Appreciate any help.

I have a table of product types, the table is layed like this:
TypeID
TypeName
ParentID
each type has a ParentID equal to one of the other types TypeID (except the very top level types) to build a hierarchy with several levels.
I need a way of giving a function a single TypeID, and have it return a table that has the the TypeID of every type underneath it in the hierarchy. it could go down several levels (like 10 or more) so it needs to recursively work...
I'm just completely lost...
I can get this to work just fine in VB... but in VB i can just use a nice little for each loop...

Hey all,
I am writing a procedure to perform a search against products in a website. It is a hierarchical setup, with websites, catalogs, category hierarchies, categories and products. So I need to get all the products that match the search, that are in categories that are in category hierarchies (category-to-category relationship), that are in catalogs that are in 1 website.
I can get the category that a matching product is in, but from there I need to recursive go up the ladder of category hierarchies until it reaches a point where the parent hierarchy is null, and then join that record with the catalogs that are in the 1 website. Here's what I thought might work:
Code:
SELECT ctlgs_CatalogCategoriesToProducts.*
FROM COMMERCE_PRODUCTS
INNER JOIN ctlgs_CatalogCategoriesToProducts ON COMMERCE_PRODUCTS.ITEMNO = ctlgs_CatalogCategoriesToProducts.ItemNo
INNER JOIN ctlgs_CatalogCategoryHierarchies ctlgs_CCH ON ctlgs_CatalogCategoriesToProducts.CategoryID = ctlgs_CatalogCategoryHierarchies.CategoryID
*** some recursive stuff***
WHILE (ctlgs_CatalogCategoryHierarchies.ParentHierarchyID IS NOT NULL)
BEGIN
INNER JOIN ctlgs_CCH ON ctlgs_CatalogCategoryHierarchies.ID = ctlgs_CCH.ParentHierarchyID
END
******
INNER JOIN ctlgs_Catalogs ON ctlgs_CatalogCategoryHierarchies.ID = ctlgs_Catalogs.RootHierarchyID
INNER JOIN ctlgs_CatalogsToWebsite ON ctlgs_Catalogs.ID = ctlgs_CatalogsToWebsite.CatalogID
INNER JOIN ctlgs_Websites ON ctlgs_CatalogsToWebsite.SiteID = ctlgs_Websites.ID
WHERE
ctlgs_Websites.ID = @website
AND COMMERCE_PRODUCTS.BLOCKED = 0
AND (
COMMERCE_PRODUCTS.ITEMNO LIKE @searchTerm
OR COMMERCE_PRODUCTS.DESCRIPTION LIKE @searchTerm
OR COMMERCE_PRODUCTS.DESCRIPTION2 LIKE @searchTerm
)
I've never used WHILE before, so I'm not sure what exactly you can put in there. Any advice would be greatly appreciated, thanks!

I have a following structure
table A
userid ReferedBy
BA
C B
Table B
Userid compID
AAlpha
Bself
Cself
now the scenario is :
the user A is from the company "Alpha"
he introduces user B, who registers in the system his company bcomes "self",
now B inturn refers user C who also registers in the system and his company is now again "self".
Now I need to generate a report of number of users that have registered under one company, for eg.
for the company "Alpha" no of users becomes 2 since A refered to two users and both of them have registered.
I m stuck with the query.
thanks in advance...
regards,
Harshal

Hi,
I have 2 tables
tblparent
parent_term_id term_id
-------------- -----------
1 2
2 3
tblname
id name
----- ------------------------------------------
1 My top parent node
2 My second node
3 my child node
If I do a search for say 'my child node' I need to display where 'my child node' is in relation to the hierarchy. i.e i need to show it's parent and if that has a parent I need to show its parent etc... and continue until there are no more parents left
So using the table details if i search for 'my child node'
I need to display this :
My top parent node -> My second node - > my child node
The id for 'My top parent node' doesn't exist in tblparent because it is the top parent
Can anybody help with doing this
Thanks in advance
