Help Convert MS Access Function To MS SQL User Defined Function
I have this function in access I need to be able to use in ms sql.  Having problems trying to get it to work.  The function gets rid of the leading zeros if the field being past dosn't have any non number characters.For example:TrimZero("000000001023") > "1023"TrimZero("E1025") > "E1025"TrimZero("000000021021") > "21021"TrimZero("R5545") > "R5545"Here is the function that works in access:Public Function TrimZero(strField As Variant) As String   Dim strReturn As String   If IsNull(strField) = True Then      strReturn = ""   Else      strReturn = strField      Do While Left(strReturn, 1) = "0"         strReturn = Mid(strReturn, 2)      Loop   End If  TrimZero = strReturnEnd Function

Help With User Defined Function
I have a UDF that takes my input and returns the next valid business day date. My valid date excludes weekends and holidays.
It works perfect except for one issue. It doesn't check to see if today's date  is a holiday.
I pass a query to sql server like so " select dbo.getstartdate('01/ 10/2007',2)"
It then moves ahead two business days and returns that date.
Here is the current code. Hopefully someone can tell me how to do the holiday check on the current date.
I really don't want to rewrite the whole script .

User Defined Function
Hi everyone,
    I am tring to pass acomma delimited string to a function  and this function is parsing the string so that I can see individual values so for example I am passing 1,2,3,4,5 as a parameter to my function and I am parsing this string so that I can write something like this
Select * from tableA where userID in(1,2,3,4)
It is working fine. Only problem is if the user passes word 'all' instead of 1,2,3,4 then I have to doSelect * from tableA
My function looks like this.  How can I modify this function if I pass 'all' as a paramater. Any help will be appreciated.CREATE FUNCTION [dbo].[ParseText2File] (@p_text varchar(4000), @p_Delimeter char(1))
RETURNS @results TABLE (id varchar(100))
AS
BEGIN
declare @i1 varchar(200)
declare @i2 varchar(200)
declare @tempResults Table (id varchar(100))
while len(@p_text) > 0 and charindex
(@p_Delimeter, @p_text) <> 0
begin
select @i1 = left(@p_text, charindex(@p_Delimeter, @p_text) - 1)
insert @tempResults select @i1
select @p_text = right(@p_text, len(@p_text) - charindex(@p_Delimeter,@p_text))
end

User Defined Function Help!
I am trying to compare the data from one table (shipments) with the data from a view. The point of the function is to match the correct territory with the account depending on the data. Basically, I this deals with accounts that are transfering from one territory to another. The transfers take effect on the first day of the month, retroactive, therefore we need to allocate the sales data to the correct territory in the shipments table. Here is my function. Can someone tell me how I can get this to work and insert a territory ID for the account that has transfered into the shipments table?

CREATE FUNCTION fnShipments ()
RETURNS @Shipments TABLE (AccountID CHAR(10), DateInvoice DateTime, DollarShipments Money, TerritoryID CHAR(10))
AS
BEGIN
INSERT @Shipments (AccountID, DateInvoice, DollarShipments, TerritoryID)
SELECT Shipments.AccountID, Shipments.DateInvoice, DollarShipments, ISNULL((SELECT TerritoryID FROM vwAccountTransfers

WHERE Shipments.AccountID = vwAccountTransfers.AccountID

AND vwAccountTransfers.EffectiveMonth =

(SELECT MIN(EffectiveMonth)
FROM vwAccountTransfers

WHERE Shipments.AccountID = vwAccountTransfers.AccountID
AND DatePart(m,Shipments.DateInvoice) < vwAccountTransfers.EffectiveMonth)),
(SELECT TerritoryID FROM vwAccountTransfers
WHERE Shipments.AccountID = vwAccountTransfers.AccountID
AND vwAccountTransfers.EffectiveMonth Is Null )
) AS Territory

I need a UDF that will do the following:

User: Will be sending me a datetime e.g '9 Nov 2004 15:00:00'
I want the UDF to do the following for me
Return in hours the difference between what the user has send and now (lets say now = '10 Nov 2004 11:00:00')
So the UDF will return to me 20.
But I dont want 20, I want the UDF to avoid any all hours which are not work related (any time after 16h00
until 8h00 in the morning), so I want this UDF to return 4. That means from '9 Nov 2004 15:00:00' I have calculated
1hr until 16h00 and 3hrs from 8 until 11h00 on '10 Nov 2004 11:00:00'

AGAIN IT MUST NOT CALCULATE WEEKENDS. Lets say '12 Nov 2004 15:00:00' was Friday and now = '15 Nov 2004 11:00:00', I must still
get 4 as a return from UDF

I would also like now to be my getdate(), but it seems like you can't use it in UDF

I only just been given this job as SQL server 7 "administrator". One of the many problems I am facing is trying to find out a way to write user defined functions - one of the millions of things you can do easily with Oracle. I have heard the rumours that SQL 7 does NOT come with "User Defined Functions" as a features. Please tell me this is not true.

And if it is true, please can anyone tell me a way to get around this?

Many thanks in advance

User Defined Function
Dear friends,

I am a new user for SQL server. Coming from an oracle background, I find it very difficult to live without user defined functions. At the moment, I urgently need to have a function returning an custom-made ID string, so that it can be used in one of my stored procedures. I have heard the rumours that SQL server 7 does NOT support user defined functions, (which SQL 6.5 does). I would be really grateful if anyone can clarify this for me, and if possible, suggest a get-around approach.

Thanks in advance!

Need Help With User Defined Function
I am accustomed to doing most of my function work in Access, but the boss would really like it if I could shedule some cubes to do the stuff that takes forever when you run it live.

To that end, I have an Access function that I call to get a field value for a query.  I would like to be able to create an User Defined Function on the SQL server and call that function as a field value in a view.  I have searched the forums and have not really found anything that wants to make sense to me as to how to do this.

The access function is as follows:

Public Function BuyerDeltas(IFSDate As Date, PODate As Date) As Long

    If IFSDate < (Date + 14) Then
        BuyerDeltas = IFSDate - 3 - PODate
    ElseIf IFSDate < (Date + 29) Then
        BuyerDeltas = IFSDate - 7 - PODate
    ElseIf IFSDate > (Date + 28) Then
        BuyerDeltas = IFSDate - 10 - PODate
    Else
        MsgBox "This should not be possible!", vbOKOnly, "Fix It!!!!!!!"
    End If

End Function

The view that this is called from contains the IFSDate and PODate fields and I am able to call the function from the access query, but this is completely different than what I have seen in the help files on SQL.

I would love to be able to keep plugging away at doing this myself, but the boss also is pushing me to get it done and he doesn't want me taking forever to do it.

Any direction would be greatly appreciated!

Calling The User Defined Function!!!
hai,
the problem is - I have created a userdefined function using SQL 2000
create function  getfulldate (@date varchar(10))returns datetimeasbegindeclare @getfulldate datetime set @getfulldate  = dateadd (mi,55,@date)
return @getfulldateend
and normally we call this in the SQL statements as
select *, dbo.getfulldate('2006-05-03')  from emp
This works fine and what I need was, I need to invoke the user-defined function like
select *, getfulldate('2006-05-03')  from emp    that is, without using "dbo".
If I call in that manner, it gives error as - 'getfulldate' is not a recognized function name.
So, here what is the purpose of dbo and can I call in my desired manner as mentioned above.
anyone guide me, thanks!

sometimes after modifying a UDF (for example adding a column to the output) the statements refer it raise an error like the function has never been modifying , than in the previous example sql server doesn't find the last added column.

If I reapply the "alter" statement script of the function all works fine.It seams there is a sort of internal cache that need to be updated ...

Nobody have never been founding a similar behavior? :confused:

Need Help Optizing A User Defined Function
Hi,
I posted a question sometime back about any one has written a function which converts a given date to a a new timezone.

As it turns out I have actually written the function and it is functionally sound.

the issue I am not facing is the performace.

The Algorithm is pretty simple.
step 1
I have create a table called TZ1 which has the TImezoneCODE (PST,EST..), daylightsavingsstart (DATETIME on which the daylight savings start), daylightsavingsend ( end of DLS) and offset (EG -8 for PST, -5 for EST etc)

step 2
I check the timezone and pick out corresponding start and enddate for daylight savings.

Step 3
Depending on where the date lies I create a new date by adding offset to the original datetime (+1) for the new date and then return this new datetime.

As simple as this looks the response time is 16 times than that of a select statement without the function.

Do you see something that I can tune to get a better response time.

Heres my code

User Defined Aggregat-Function
 

Hi,
I'm trying to write an aggregat in c#.It's no problem for sum or multiplication aggregates.
But when I try to use an array to stor the values in it, to compare them with each other,
I get the Message:
 
 

Fehler 1 Type "AggregatClr.AggregatClr" is marked for native serialization, but field "Werte" of type "AggregatClr.AggregatClr" is of type "mscorlib.System.Array" which is a non-value type. Native serialization types can only have fields of blittable types. If you wish to have a field of any other type, consider using different kind of serialization format, such as User Defined Serialization. AggregatClr

And when I try it with User Defined instead of Native:
 
Fehler 1 Type "AggregatClr.AggregatClr" is marked for user-defined serialization, but does not implement the "System.Data.Microsoft.SqlServer.Server.IBinarySerialize" interface. AggregatClr

 
 
What does that means? How can I do that??
Is it possible to use an Array in a User Defined Aggregat??
Thanks

CLR User Defined Aggregate Function
I am trying to modify the C# example given in the "Invoking CLR User-Defined Aggregate Functions" in SQL Server 2005 Books Online.  I want to add a parameter that is used as the list delimeter, instead of the hard coded comma that is used.  I am not a C# programmer and don't know where to begin.

New Column From User Defined Function
I have a user defined function (UDF) that takes 2 parameters.  These parameters will be mapped from OLE DB source column values.  I want the function result to be a new column that will be mapped to an OLE DB destination.  Should this be done using a lookup task, OLE DB command task, or...?  If this is possible I would appreciate a very specific example of how it's done.

BTW I tried using a lookup task with a SQL command before the UDF idea occurred to me and ran into problems using parameters in the SQL query:

Parameter Information cannot be derived from SQL statments. Set parameter information before preparing command.

I've seen the posts about going to the advanced tab and messing with the parameters there but I was hoping using a UDF would be easier, if it can be done.

Thanks.

Using A User Defined Function From A OLE DB Command
 

Hi all, I've tried all types of formats use this function and coming up with errors
the function works fine in SQL so not sure of the proper format to call a function with variaibles
 
have tried
EXEC  EquivalentCase = dbo.udfEquivalentCase(@ConversionValue1= ?,@ConversionValue2 = ?, @CasesSold = ?, @CasesSold=?, @OwnershipCode = ?, @BusSegCode = ? )
 
and
dbo.udfEquivalentCase(?,?,?,?,?)
 
and
select
dbo.udfEquivalentCase(?,?,?,?,?)
 
is there somewhere that provides proper syntax for executing a user defined function from a OLE DB command?
Thanks

Error Notification From User Defined Function
Is there any reason why I shouldn't cause an arithmetic error(say bydividing by zero) in a User Defined Function for a situation where in astored procedure you would use RAISERROR or in code you would throw anexception?In most situations, I can check the return value of the UDF to see thatit is valid. However, I want to sum the output of UDF and thereforecannot check the return value. Errors should be so rare that I wouldrather not use a cursor to do the sum--and take the peformance hit.Following is the code:SELECT SUM([dbo].[udf_MyFunction]([Column1],[Column2]))FROM tblMyTableThanks ~ Matt

Storing Variables From A User-defined Function
I've looked all over but can't find a solid answer. I've got afunction that runs from a View and when the function runs the firsttime it is calculating a Temperature for a group of Formulas. What Iwant to do is calculate this temperature in the UDF on the first passand store it somewhere (table, global variable etc.). On everyexecution after that I'd like to use the value stored so I don't haveto recalculate the value again for the specific group defined.I've looked at storing the data in a table from the UDF but UDF'sdon't support dynamic SQL statements and can't run a stored procedure.The key here is we have a view that calls a UDF (user-definedfunction). Using SQL 2000.Any ideas would be very helpful. Thanks.

Optimization Required For User Defined Function
Hi,

I've an UDF which inside has two query joined by union and it 's similar to this

select * from Table1 .... (several conditions)
union
select * from Table2 .... (several conditions) (this could takes long time to run)

Since i can't write dynamic sql into UDF , i can't avoid to insert Table2 into the query but to improve permormance I've seen how costant can help me.
For Example if I change my UDF in

select * from Table1 .... (several conditions)
union
select * from Table2 Where 1=2 AND (several conditions)

Optimazer is able to skip completely the second execution, so i need to transform 1=2 into a dynamic condition for example test a field table existence.
select * from Table2 Where Exist (select * from Table3 where Field1=1)

That is why i try to write a single UDF can adapt itself to several situations using second condition only where is necessary and not always.
The problem is the dynamic condition for simple could be, wasn't recognize as costant.

For Example
select top 1 * from MyTable where (select 1)=2
select top 1 * from MyTable where 1=2

If you see the execution plan of these 2 queries you could see that the first takes more than 80% of execution time and in the second less than 20%.
Moreover the second plan use a costant scan unlike the first doesn't it.

Do anyone know a way to tell to optimizer to use a simple condition as constant ? This improve drastically my UDF performance..... :( :(

Thanks.
