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
View 4 Replies View RelatedHi there, Any tips on my problem would be most welcome...
right, the scenario.
A web Blog
blogger1 posts a blog_entry, e.g I love the simpsons
blogger2 comments on that blog_entry, e.g No, I hate the simpsons
Blogger3 comments on that comment, ie, How can you hate the simpsons.
so you can comment on a comment on a comment etc.. lool.
right, i have got two tables... Blog_entry & comment. i need to be able to search for a blog_entry + all the comments on that blog_entry..
at the moment i can search for the comments on the blog_entry using the FK in the comment table.
blog_entry
INSERT INTO Blog_Entry VALUES(0001,'I love the Simpsons');
comments
INSERT INTO Comment VALUES(0001,' No I hate the simpsons, cID 1000);
but i need to be able to search for the comments on comments
INSERT INTO Comment VALUES(0001,' How can you hate the simpsons, cID1000);
hopefully you can see the problem here, with only one comments table how can i get the search for the comment on the comment.. there’s nothing linking them...
I could make a sub comments table, and use a FK (as with the blog_entry & first comment)
but then I would have to make another sub sub table to be able to get those comments on the first sub table... this would go on and on for each comment on comment.
you can see the cID1000 (comment PK) I can't use this to get the comment because its duplicating the PK...
So, I need to be able to search for the comments on comments… eg. I need to be able to search for blogger2, and any comments that were made on his comments.
Someone I know mention using recursion to get the comment on comment info, is this right ?
Hehe, I hope you understand what im asking here… the is my first exploration of SQL, so any tips, hints, would be most welcome….
Thanks loads…
PS: if there anything you don’t understand about what I have written, or what im asking… please say so…

I am trying to build the value off hierarchy that will be later inserted in the linage and Depth column. I am trying to do so using recursion . the rulles for recording the linages as as follows Lineage = parent.Lineage + Ltrim(Str(ParentID,6,0)) + '/'
here is my code below

select * from BuildHierarchy
but it does not increment Depth or builds Lineage .What am I doing wrong?
How to write a recursive Procedure in SQL Server to find factorial of 50?
The recursive call is limited to 32..could any one help me out.
Thanks in Advance
Guys,
I desperately need your help.
what i need to do is call a function getdate to return dates recursively
like so
classdate=getdate(class#, repeat, sportcategory,date)
while (classdate <yearend)
begin
classdate=getdate(class#, repeat, sportcategory, classdate)
end
I want to use the date returned and keep calling that function till the yearend is reached, to get a bunch of dates
declare @startDate datetime
with cteStartDate as
(
select x= classdate,
repeat,
class#,
sportcategory,
yearend
from sports
union all
select x=getdate( classdate,
repeat,
yearend),
repeat,
class#,
sportcategory,
yearend
from cteStartDate
where x < cteStartDate .yearend
)
I tried using cte for this, it only returns one date for everything, as opposed to an array of dates, how do i solve this problem.Any
insight will be greatly apprecaited.
Thanks
Hi there! I have an application that uses stored procedures wuth CTE statements to populate trees from database. Every second I need to populate 100-300 trees each one of them has 15-20 nodes. I checked those procedures with profiler and payed attention that populate procedure with CTE is slower that others (without CTE) per 1000 times! Would procedures with recursion faster than same ones with CTE? I am asking because I read somewhere that CTE is becomes slower while populating little chunks of data. Is that right and I should use recursions?
And second question: here the code -
Code Snippet
;WITH dt (Id, NodeText, PId, State, RowNumber) AS
(
SELECT Id, NodeText, PId, State, ROW_NUMBER() OVER(ORDER BY Id) AS RowNumber
FROM DataTable
WHERE Id = 1
UNION ALL
SELECT d.Id, d.NodeText, d.PId, d.State, ROW_NUMBER() OVER(ORDER BY d.Id) AS RowNumber
FROM DataTable AS d
INNER JOIN dt ON dt.Id = d.PId
)
SELECT * FROM dt
This is how I populate a tree with CTE. Could you give me some example how to do exactly same but with recursion?(without CTE). Thank you!

I have a multi-level folders table, named folders with attributes of folder_id, parent_id and user_id, and have another table, users, contains all the user_id. I need to list all the users for each folder which has parent_id = 0 and its all sub-folders' users into one table. I have created a function to return a table with folder_id and user_id for one single folder. However, I don't know how to use this function to get the sub-folder's users and merge them together as one single table.
Here is my function:
CREATE FUNCTION [dbo].[FolderUsers] (@fid int) RETURNS Table AS Return (select folder_id, f.user_id from folders f, users u where f.user_id = u.user_id and folder_id = @fid)Go
where @fid is the top folder with parent_id = 0 at here, the next level sub-folder's parent_id would be = @fid.
I am thinking to have recursive call from the parent_id = @fid that returns another table and have to concatenate to the called table. I have been thinking of store procedure, "insert into" and so on, but don't know how to implement it.
Do you have any good inspiration for me? Thank you in advance!

I've encountered some strange behavior in a recursive procedure I'mwriting for a bill of materials. First let me ask directly if what Ithink is happening is even possible:It seems like the procedure is not following the recursion in serialorder, but in parallel. In other words, after one instance of theprocedure calls itself, it continues executing lines below therecursion before the recursion is done. Is that possible? I lookedfor SQL Server Options that might deal with recursion or threading butI couldn't find anything.Now let me explain what's happening in terms of the BoM. All the rowsI expect are returned, but not in the correct order. Let's assume thefollowing tree:1|-2| |-5| | |-7| | -8| -6| -9|-3| |-10| |-11| | |-13| | -14| | |-15| | |-16| | -17| -12| -18| -19| -20| |-21| -22-4-23|-24-25-26This is stored in table P using MemberID and ParentID fields. Forexample,MemberID ParentID-------- --------1 NULL2 13 14 15 26 2(etc...)Based on how I wrote the recursion (I will provide the procedurebelow), I would expect output when starting from MemberID of 1 to looklike this:MemberID Depth Sort-------- ----- ----2 1 15 2 27 3 38 3 46 2 59 3 6(etc... basically, the line order of the graphical tree above, or acounter-clockwise traverse around the tree)Instead, I get this (I'll provide the whole thing because I don't seea pattern):MemberID Depth Sort-------- ----- ----2 1 15 2 23 1 210 2 37 3 34 1 36 2 39 3 423 2 48 3 411 2 413 3 512 2 524 3 525 3 618 3 614 3 615 4 719 4 726 4 720 5 816 4 817 4 921 6 922 6 10Call me crazy, but it looks like my tree was parsed in the same orderthat a set of dominos arranged in the same shape would topple. Theonly way I could see that happening is if the recursion is non-linear,allowing both children and siblings to be parsed simultaneously. Itwould also explain why my sort counter didn't increment properly, butthe depth counter is always correct.Now here are the procedures. There's also a Qty column, since this isa BoM after all, but I didn't need to mention it for my illustrationof the problem above.CREATE PROC makebom @root bigint---- This would be called by the client to find all the parts andquantities-- under a specific part (@root)--ASSET NOCOUNT ONCREATE TABLE #result (MemberID bigint, Qty bigint, Depth bigint, sortbigint)EXEC bomrecurse @root, 1, 0SET NOCOUNT OFFSELECT MemberID, Qty, Depth, sort FROM #result ORDER BY sortGOCREATE PROC bomrecurse @root bigint, @depthcounter bigint,@sortcounter bigint---- This is the recursive procedure, called once by makebom, butrecalling-- itself until the whole tree is parsed, filling the #result table--ASDECLARE @memberid bigint, @qty bigint, @nextdepth bigintDECLARE children_cursor CURSOR LOCAL FORSELECT MemberID, Qty FROM PWHERE ParentID = @rootORDER BY MemberIDOPEN children_cursorFETCH NEXT FROM children_cursorINTO @memberid, @qtyWHILE @@FETCH_STATUS = 0BEGINSET @sortcounter = @sortcounter + 1INSERT INTO #result VALUES (@memberid, @qty, @depthcounter,@sortcounter)SET @nextdepth = @depthcounter + 1EXEC bomrecurse @memberid, @nextdepth, @sortcounterFETCH NEXT FROM children_cursorINTO @memberid, @qtyENDCLOSE children_cursorDEALLOCATE children_cursorGOI'm surprised this even worked as well as it did because I'm a newbiewhen it comes to stored procedures and I put this together fromexamples I found around this group, online and in the T-SQL Help. Sofeel free to comment on other aspects of my code or approach, but I'mmost interested in understanding the behavior of this recursion.
View 4 Replies View RelatedI have a bit of an issue with an app I'm working on. The app integrates two different SQL Server applications - both of which employ recursive triggers to some extent. My integration basically serves to establish a link between different tables in the applications, and maintains consistency between the two applications (where common fields exist) by employing INSERT, UPDATE, and DELETE triggers.
In order to prevent infinitely recursive triggers (AppA.TableA's update trigger updates AppB.TableA. AppB.TableA's update trigger updates AppA.TableA...and so on, and so on) I need to be able to somehow selectively prevent these triggers only from executing recursively. For example, if the trigger in AppA is what calls the trigger in AppB, I do not want AppB's trigger to fire (and vice versa).
Further Information:
The apps may be on the same, or different, SQL servers.
I'm fully aware of the database-wide options to disable trigger recursion (ALTER DATABASE), but I can't disable recursion for the balance of the triggers in the databases.
The integration will run on either SQL 2000 or SQL 2005 - and perhaps one server on 2000, and one on 2005 (depending upon the deployment).
I'm perfectly amenable to handling it in the trigger code, if possible, but I'm at a bit of a loss as to how to properly and efficiently manage that.
I know that SQL Server will kill infinitely recursive triggers once it detects them, but that doesn't exactly solve my original problem.
Thanks very much for any input you can offer.

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.

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.
