Can't Create Recursive Function

Aug 1, 2007

Greetings.

I'm having trouble creating a recursive function in T-SQL (SQL Server 2000).

I've got a table that has an ID column and a ParentID column. Each row can have a value in the ParentID column that references the ID column of another record - I'll call such rows "child records". I'll cal the row referenced by the ParentID the "parent record".
Each child record can itself have another child record.

I need a function that will take an ID column value as a parameter, and walk up the chain of parent records until I get the first record in the series and return that record's ID value. I'll call that record the "UrParent record".

I'm trygin to create a recursive function called ufunc_ST_GetUrParentCertNum. In the function, there is of course a recursive call to itself - GetUrParentCertNum. However, when I try to run the CREATE FUNCTION script, I get the error:
Server: Msg 195, Level 15, State 10, Procedure ufunc_ST_GetUrParentCertNum, Line 26
'ufunc_ST_GetUrParentCertNum' is not a recognized function name.


I tried the same thing with a Stored Procedure, and that worked fine. However, I really want this to work as a function.

Does anyone have advice on how I can achieve this?
Thanks in advance.

How To Convert Recursive Function Into Recursive Stored Procedure

Jul 23, 2005

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

Help With Recursive Function

Nov 1, 2007

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...

any ideas?

Recursive Function

Feb 1, 2005

I am trying to write a recursive function which allows me to provide a hierarchical structure from an employee table but I am getting an error

Server: Msg 512, Level 16, State 1, Procedure GetEmployee, Line 10
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.


Is there a way in which I can write a recursive function to do this. Or would I need to use cursors, multiple functions???
Any help or examples would be great. Thanks for your help

CREATE FUNCTION GetEmployee(@EmpID as int)
RETURNS @Employee Table
(
StaffNo int,
ParentStaffNo int
)
AS
BEGIN
DECLARE @ManagerID int
SET @ManagerID = (SELECT [id] FROM eii.dbo.test WHERE Parent_ID = @EmpID)

IF @ManagerID IS NOT NULL and @ManagerID > '' and @ManagerID <> @EmpID
INSERT INTO @Employee
SELECT [id],parent_id FROM eii.dbo.test Where [id] = @ManagerID
UNION
SELECT * FROM GetEmployee(@ManagerID)

Help With Recursive Function

Jul 20, 2005

I am writing a function which I hope to use as a column value in aselect query. The function recursively walks a taxonomic heirarchy,extracting the name for an organism at the taxonomic level requestedby the user. I'm having trouble figuring out the syntax to call thefunction from itself (see **1), and the value returned.When I test the funciton, it says 'commands completed successfully',but nothing is returned. This is in SQL2000, runing on Windows2000.The table the function acts on is:CREATE TABLE [dbo].[tblbenthictaxa] ([tsn] [int] IDENTITY (1, 1) NOT NULL ,[rank_id] [int] NOT NULL ,[dir_parent_tsn] [int] NULL ,[req_parent_tsn] [int] NOT NULL ,[taxa_name] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOTNULL) ON [PRIMARY]GOReqParentTSN is the recursive link to rows in the table;Level is the taxonomic level the user requested (an integerrepresenting Order, Family, Genus or Species).CREATE FUNCTION dbo.CBN_RecursTaxa (@ReqParentTSN int,@Level int)RETURNS varchar(100) ASBEGINDeclare @Rank int,@taxaname varchar(100)SELECT @ReqParentTSN = tblbenthictaxa.req_parent_tsn,@TaxaName = tblbenthictaxa.taxa_name,@Rank = tblbenthictaxa.rank_idFROM tblbenthictaxaWHERE tblbenthictaxa.TSN=@ReqParentTSNif @Rank > @Level**1 --exec CBN_RecursTaxa @ReqParentTSN, @LevelRETURN @TaxaNameENDThanks in advance for any help,Tim

Recursive Query Quesiton - Table Function

Jul 20, 2005

I have a database which stores information about organisms collectedduring sediment toxicology research. For each sample, organisms insediment are collected and identified taxonomically (Order, Family,Genus, Species).Taxonomy lookup information in the database is stored in a recursivetable in the form:TSN (taxa serial number)Rank (Order, Family, Genus, Species)NameParent_TSN (related Taxa at higher taxonomic level)When the number of a particlar organism collected is entered into thedatabase, the count is stored along with the lowest level TSN theorganisms were identified to.Okay - now the problem. Depending on the type of analysis being done,a user may want organism counts at the lowest level, or rolled up to ahigher taxonomic level (usually Family). Can I write a recursivefunction which will cycle through the Taxonomy database, and providethe name of the organism at the appropriate taxonomic level? Is this areasonable approach with regard to speed and efficiency?Something Like:SELECT sample_id, 'Get Name Function(Rank, TSN)', Sum([count]) ASNoTaxa FROM dbo.tblbenthicResults could then be grouped and summed on the Name, to summarisedata for each sample/taxa.Is this a reasonable approach? Or is there a better one? Did I explainthe problem well enough?Thanks in advance,Tim

Create Table With Recursive Relationship

May 16, 2006

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 ?

SQL Server 2008 :: Recursive CTE On Inline Table Valued Function

Jun 22, 2015

I have a recursive CTE on an inline table valued function. I need to set the MAXRECURSION option on the CTE, but SQL Server is complaining with "Incorrect syntax near the keyword 'OPTION'".

It works fine on non-inline function. I couldn't find any documentation indicating this wasn't possible.

I can use the MAXRECURSION option in call to the function

SELECT * FROM MyFunction ()
OPTION ( MAXRECURSION 0 )

but that means that the user needs to know the "MyFunction" uses recursive CTE, which defeats the purpose of the abstraction.

I'm running SQL Server 2002 and trying to create a User Defined Function. However, everytime I try to save the script I get Error 170 Incorrect Syntax near 'FUNCTION'.

This happens if I create the Function from Code or use the Enterprise Manager. I'm logged in with 'sa' privs, so I don't think it's a privilege issue. I'm well confused.

Anyone help?

Is There Anyway To Create A View Within A Function

Hi, Is there anyway to create a view within a Function? The code is as below. I execute the code between "BEGIN" and "END". SQL Analyzer report error that said

'CREATE VIEW' must be the first statement in a query batch.

I could make the variable constant in SELECT statement, but I'm wondering if there is a way to make CREATE VIEW as part of code piece.

WHERE (((dbo.tblTRACT.STR)=@TRS))



)

GO

I understand now I can create a view of the function Simply by using the function name in my FROM statement. However I get an error that arguments provided do not match parameters required. However, I'm not getting the prompt to enter my criterion. Is my error in my function statement? I can't save the view. I also understand I could use a pass-through query. Is there some sort of guidance or tutorial on that to which you could point me?
Thanks for your time.

Fail To Create CLR Function In SQL 2005

Apr 22, 2008

Can anyone help me to create a URL decode user defined function in SQL Server 2005?
I want to use the method [System.Web.HttpUtility.UrlDecode] in .net framework, and I try to add it as a CLR function to SQL Server but always fail. It depends on [System.Web.dll], and when I try to create assembly [System.Web] using following scripts, it will fail:

CREATE ASSEMBLY [System.Web] FROM 'C:WindowsMicrosoft.NETFrameworkv2.0.50727System.Web.dll'
WITH PERMISSION_SET = UNSAFE

Error:
CREATE ASSEMBLY for assembly 'System.Web' failed because assembly 'System.Web' is not authorized for PERMISSION_SET = UNSAFE.
The assembly is authorized when either of the following is true:
the database owner (DBO) has UNSAFE ASSEMBLY permission and the database has the TRUSTWORTHY database property on;
or the assembly is signed with a certificate or an asymmetric key that has a corresponding login with UNSAFE ASSEMBLY permission.
If you have restored or attached this database, make sure the database owner is mapped to the correct login on this server. If not, use sp_changedbowner to fix the problem.

I have searched the MSDN and then add following scripts before mine:

ALTER DATABASE [DatabaseName] SET TRUSTWORTHY ON

CREATE ASYMMETRIC KEY SystemWebKey FROM EXECUTABLE FILE = 'C:WindowsMicrosoft.NETFrameworkv2.0.50727System.Web.dll'
CREATE LOGIN CLRLogin FROM ASYMMETRIC KEY SystemWebKey
GRANT UNSAFE ASSEMBLY TO CLRLogin

But unfortunately it fails again with same error.

Create A TO_DATE Function For Use In SQLServer 2005

Feb 28, 2008

Hi ,

I 'm working with visual studio 2005 and I have created an SQLServer Project.
I'm using the CLR functionality which comes with SQLserver 2005. This means that I can write VB.nEt code and use it inside Sqlserver 2005.So far so good.
I am now inside the .NET
I have created a Function(must remind you that I have created an SQLserver Project) which takes two string arguments. The date value in a string format and the string format.

In Our case the function returns a string.It will return a datetime although.
So we have

Dim Datetime_Val As DateTime = Nothing
Dim Date_Val As Date = Nothing
Dim StrTemp As String = ""
Dim StrDateTemp As String = Nothing
Dim StrTimeTemp As String = Nothing
Dim ls_return As String = Nothing
Dim lindexof As Integer
Dim Counter As Integer = 0

lindexof = 0
Select Case StrFormat
Case "DD-MM-YYYY HH24:MIS"
For Counter = 1 To 2
lindexof = StrDate.IndexOf("-", lindexof + 1)
Next
lindexof += 5

StrDateTemp = StrDate.Substring(0, lindexof).Trim
StrTimeTemp = StrDate.Substring(StrDateTemp.Length, StrDate.Length - StrDateTemp.Length).Trim
ls_return = StrDateTemp & " " & StrTimeTemp

End Select

The above is a simple code. As you can see I'm trying to convert the TO_DATE function ,which work with ORACLE, to make it work with SQLServer 2005.
I've been trying unsuccessfully to combine the variables StrDateTemp and StrTimeTemp into a datetime value. I used the following code but nothing

Datetime_Val = CDate(StrDateTemp & " " & StrTimeTemp)
Didn't work

Datetime_Val = Convert.ToDateTime(StrDateTemp & " " & StrTimeTemp)
Didn't work

Datetime_Val = DateTime.Parse(StrDateTemp & " " & StrTimeTemp)
Didn't work

Inside SQlServer I used this SQL statement

Select dbo.TO_DATE('31-12-1990 00:26:46','DD-MM-YYYY HH24:MIS')

But I am receiveing an error. I want to avoid changing all of my applications with a specific format.This sql statement without the dbo prefix I'm using in Oracle. I want to keep the format of the SQL and let VB.NET do the parsing for me. It is easier for me to put in my SQLs the dbo infront rather changing the complete SQL.
I have two questions . How am I going to create a TO_DATE function which Oracle uses and write something similar in SQLserver ?
And If I cannot do that how am I going to get the database 's datetime format and create with VB.NET the Datetime value from the two variables ?

My problem I believe is quite complex. I would be mostly appreciated if you could help me on this.

Thank you

I would like to create a function that take a value and run some logic and output the value

I have a table like this

Table A
value
*
001
004.00
3.0
1.22

Logic I want to run is

The value that you are passing is numeric and numeric with only decimal 0 value, and then convert it to integer otherwise leave as it is

So if I run a query something like this

Select value, fn_convertointerger(value) as converted_value from TableA

I will get

Value converted_value
* *
001 1
004.00 4
3.0 3
1.22 1.22
2.02 2.02
4.000 4
Jkil& Jkil&

How can I create a function like this to convert specific numeric value?
