Aug 1, 2005

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

Jan 10, 2007

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 .
Code---------------------------------------------------------
SET QUOTED_IDENTIFIER OFF GOSET ANSI_NULLS OFF GO
--DROP FUNCTION GetStartDate
--declare function receiving two parameters ---the date we start counting and the number of business days
CREATE  FUNCTION GetStartDate (@startdate datetime, @days int)   RETURNS datetimeASBEGIN
--declare a counter to keep track of how many days are passingdeclare @counter int
/*Check your business rules.  If 4 business days means you count starting tomorrow, set counter to 0.  If you start counting today, set counter to 1*/set @counter = 1
--declare a variable to hold the ending datedeclare @enddate datetime
--set the end date to the start date.  we'll be -- incrementing it for each passing business dayset @enddate = @startdate
/*Start your loop.While your counter (which was set to 1), is less than or equal to the number of business days increment your end date*/WHILE @counter <= @days
BEGIN
--for each day, we'll add one to the end dateset @enddate = DATEADD(dd, 1, @enddate)
   --If the day is between 2 and 6 (meaning it's a week   --day and the day is not in the holiday table, we'll    --increment the counter   IF (DATEPART(dw, @enddate) between 2 and 6) AND       (@enddate not in           (           select HolidayDate            from tFederalHoliday            where [HolidayYear] = datepart(yyyy,@enddate)         )       )   BEGIN      set @counter = @counter + 1   END

User Defined Function

Aug 17, 2005

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
insert @tempResults select @p_text
insert @results
select *
from @tempResults
return
END

User Defined SQL Function

Dec 14, 1999

How can I create a user defined function in SQL and call it inline from a SQL statement? I need the ability to execute a statement such as:

select myFunc(x,y) from table

I need myFunc(x,y) to return a value, not a recordset and use that value in the select statement. Any and all ideas would be appreciated.

User Defined Function

Aug 2, 1999

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!

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
FROM Shipments

ORDER BY Shipments.AccountID, Shipments.DateInvoice;
RETURN

User Defined Function

Nov 10, 2004

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

Need Help With User Defined Function

Apr 6, 2006

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!!!

Aug 28, 2007

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!

Need Help Optizing A User Defined Function

Mar 3, 2004

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 Function Issue

I have a user defined function that may be called multiple times inthe same query - here's a rough exampleselect col1, get_random_number(), col2, col3, get_random_number() fromtable1The problem I am having is that I need to have both calls to the userdefined function return the same value if it is called multiple timesfor one row. The values returned from the query would be somethig likethis -John 23456 Engineer Junior 23456Frank 33333 Engineer Senior 33333Tom 80331 Engineer Junior 80331I have thought about having two seperate udf's likeget_random_number() and use_last_random_number(), but I'm not sure howto store the value of the get_random_number() to be used byuse_last_random_number(). These udfs are used in bulk load requests,so performance is a big issue. Any suggestions would be greatlyappreciated. I know the example is kind of silly, but I think itillustrates the problem.

New Column From User Defined Function

May 21, 2006

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.

User Defined Aggregat-Function

Dec 7, 2007



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

Oct 4, 2006

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. Please help!

using System;
using System.Data;
using Microsoft.SqlServer.Server;
using System.Data.SqlTypes;
using System.IO;
using System.Text;

[Serializable]
[SqlUserDefinedAggregate(
Format.UserDefined, //use clr serialization to serialize the intermediate result
IsInvariantToNulls = true, //optimizer property
IsInvariantToDuplicates = false, //optimizer property
IsInvariantToOrder = false, //optimizer property
MaxByteSize = 8000) //maximum size in bytes of persisted value
]
public class Concatenate : IBinarySerialize
{
/// <summary>
/// The variable that holds the intermediate result of the concatenation
/// </summary>
private StringBuilder intermediateResult;

/// <summary>
/// Initialize the internal data structures
/// </summary>
public void Init()
{
this.intermediateResult = new StringBuilder();
}

/// <summary>
/// Accumulate the next value, not if the value is null
/// </summary>
/// <param name="value"></param>
public void Accumulate(SqlString value)
{
if (value.IsNull)
{
return;
}

this.intermediateResult.Append(value.Value).Append(','); /// I want to change to comma to a variable
}

/// <summary>
/// Merge the partially computed aggregate with this aggregate.
/// </summary>
/// <param name="other"></param>
public void Merge(Concatenate other)
{
this.intermediateResult.Append(other.intermediateResult);
}

/// <summary>
/// Called at the end of aggregation, to return the results of the aggregation.
/// </summary>
/// <returns></returns>
public SqlString Terminate()
{
string output = string.Empty;
//delete the trailing comma, if any
if (this.intermediateResult != null
&& this.intermediateResult.Length > 0)
{
output = this.intermediateResult.ToString(0, this.intermediateResult.Length - 1);
}

return new SqlString(output);
}

public void Read(BinaryReader r)
{
intermediateResult = new StringBuilder(r.ReadString());
}

public void Write(BinaryWriter w)
{
w.Write(this.intermediateResult.ToString());
}
}

Using A User Defined Function From A OLE DB Command

Feb 18, 2008



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

Cannot Find Either Column Dbo Or The User-defined Function

Oct 14, 2007

 Hi, I have a stored procedure that calls a scalar function.  It works fine on my development database, but on my production database, I get this error when trying to execute the procedure: Cannot find either column "dbo" or the user-defined function or aggregate "dbo.MyFunction", or the name is ambiguous. However, I am able to execute the function outside of the procedure like this: select dbo.MyFunction(0, 0)  Anyone have idea? I can't figure it out.
