MS SQL Server :: Calling User-defined Function Without 'dbo.' -- Possible?

Stored Procedure And Calling User Defined Function
I seem to be getting tasks that I am not familiar with these days. I am a
guy that has coded it all in the asp page or in the code behind in .NET.
This problem is outlined below and I need a help / advice on doing this. I
had the flow of the 3 parts to it expanded below. A call is made to a Stored
Procedure, The SP then calls a user defined function that runs SQL, this
returns a 1 or 0 to the SP which then returns the value back to the call on
the asp page. This is a lot I know but it is the way the lead guy wants it
done. Any help so I can keep most of the hair I have left is appreciated :-)

Short list of process flow:

1. Form.asp calls to rx_sp_HasAccessToClient in SQL SERVER

2. rx_sp_HasAccessToClient then calls ab_HasAccessToClient

3. ab_HasAccessToClient runs SQL command on db and sends return bit back to
rx_sp_HasAccessToClient

4. rx_sp_HasAccessToClient then sends this back to the call in the Form.asp
page

5. Form.asp then checks the Boolean and if 1 then show or if 0 then deny.

<FLOW WITH CODE AND FUNCTIONS :>

This is not the correct syntax but is showing what I understand sort of how
this is to be done so far.

This panel loads up the Vendors and id's when the user clicks on the link
"view detailed list of vendors associated with this client". This is the
beginning of the process.

This is code in Form.asp

Dynamic Query Calling User Defined Function
I have the following procedure, that calls a Padding function to pad characters to a field.

Here is what the procedure looks like

Code:

CREATE PROCEDURE [dbo].[Pad_Left]

@Table VARCHAR(255),
@Column VARCHAR(255),
@PadChar CHAR(1),
@PadToLen INT

AS

DECLARE @Query Varchar(5000)

SET @Query = 'UPDATE ' + @Table + '

SET ' + @Column + ' = dbo.Function_PadLeft(' + @Column + ', ''' + @PadChar + ''', ' + @PadToLen + ')'

EXECUTE(@Query)
GO

When I run this I get the error

Server: Msg 245, Level 16, State 1, Procedure Pad_Left, Line 13
Syntax error converting the varchar value 'UPDATE Lincoln

SET baths = dbo.Function_PadLeft(baths, '0', ' to a column of data type int.

But when I just run this query, it works

Code:

CREATE PROCEDURE [dbo].[Pad_Left]

@Table VARCHAR(255),
@Column VARCHAR(255),
@PadChar CHAR(1),
@PadToLen INT

AS

UPDATE Lincoln

SET Baths = dbo.Function_PadLeft(Baths, '0', 4)

GO

Why would one work but not the other? I don't understand, as they are the same thing, just one calls the function dynamically?

I must be missing something very obvious

Thanks for any help!

Calling Managed CLR Procedure From Inside User Defined Function -- How To ?
I have several UDFs created. Inside one of the UDFs I need to execute a dynamic SQL statement and then take that result and do something else with it, before returning the final value.

I know you can not execute a stored proce from inside a function. I also know you can not use the EXEC statement.

I did read that you could use an external stored procedure and/or managed CLR procedures inside a function.

I have created a managed procedure CLR (C#) that simply executes a passed statemetn and returns the value to the calling routine. I have this all coded and is working fine.

However, I am struggling with knowing how to call this CLR procedure from inside my function, seeing how I can not use EXEC statement.

Any advice on how to do this?

Thanks,
Bruce

Calling User-defined Functions In Another DB

Any ideas/suggestions? I really don't want to maintain seperate copies of the functions across 5+ databases.

Calling User-defined Functions In OLE DB Command Transformation
Hi

We have a user-defined function that can be called directly via SQL (in SQL Server Management Studio) without error. We would like to use this function to populate a column, whist data is being processed within Integration Services. Using an OLE DB Command transformation to achieve this would seem the most appropriate.

The following was inserted for the SQLCommand property:

EXEC ? = dbo.GetOrderlineStatus(@dt_required = ?, @dt_invoice = ?, @dt_despatch = ?, @ch_status = ?, @si_suffix = ?, @re_quantity = ?, @vc_invoice_id = ?, @vc_order_id = ?)

However, when the Refresh button is pressed we are presented with the error below:

Error at Load Orderline [OLE DB Command [15171]]: An OLE DB error has occurred. Error code: 0x8004E14. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x8004E14 Description: "Invalid parameter number".

If we use SET instead of EXEC (e.g. SET ? = dbo.GetOrderlineStatus(@dt_required = ?, @dt_invoice = ?, @dt_despatch = ?, @ch_status = ?, @si_suffix = ?, @re_quantity = ?, @vc_invoice_id = ?, @vc_order_id = ?)) the following error is produced:

Any assistance would be greatly appreciated.

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))

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 ()

BEGIN
INSERT @Shipments (AccountID, DateInvoice, DollarShipments, TerritoryID)

I need a UDF that will do the following:

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

User Defined Function
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?

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!

Q2. How can result of a select query with "FOR XML RAW" clause be converted into a single string?

Background of the above 2 questions:

I want to execute a simple select query which besides selecting different columns also calls a user defined function which should execute a select query and return back the result as XML string to the calling select query.

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!

This is driving me crazy.I need to create a UDF that would return a TRUE/FALSE (bit) value basedon a comparison it does.CREATE FUNCTION dbo.SelectedByApplication(@ApplicationID int,@TableToChecknvarchar(50),@ColumnToComparenvarchar(50),@ValueInTableint)RETURNS BIT ASBEGINDECLARE @SQLNVARCHAR(1000)DECLARE @Param NVARCHAR(500)DECLARE @Result intSET @SQL = N'SELECT @result = COUNT(*) FROM [' + @TableToCheck + '] '+'WHERE [' + @ColumnToCompare + '] = @ValueInTable ANDApplicationID = @ApplicationID'SET @Param = N'@result int out, @ValueInTable int, @ApplicationIDint'EXECUTE sp_executesql @SQL, @Param, @result out, @ValueInTable,@ApplicationIDif @result > 0return 1return 0ENDAll I need the function to do is fill in a column based on whetherthere is a relation between a list of data and the item. I'm trying touse it in the following query:SELECT *, EXEC dbo.SelectedByApplication(4, 'IPM_Application_DataType','DataTypeID', DataTypeID)FROM IPM_DataType DTThe idea is to make this call and then be able to populate a list ofcheckboxes based on the information it returns. It should returnsomething similiar to:Column1 Column2 UDFColumn1 SomeValue 02 OtherValue 13 DifferentValue 04 LastValue 1After reading some of the posts and discovering you can't executedynamic SQL in a UDF I decided to split the function into a functionand stored procedure:CREATE FUNCTION dbo.SelectedByApplication(@ApplicationID int,@TableToChecknvarchar(50),@ColumnToComparenvarchar(50),@ValueInTableint)RETURNS BIT ASBEGINDeclare @Result INTEXEC DynamicCompare @ApplicationID, @TableToCheck, @ColumnToCompare,@ValueInTable, @Resultif(@Result > 0)return 1return 0ENDCREATE PROCEDURE dbo.DynamicCompare(@ApplicationID int,@TableToChecknvarchar(50),@ColumnToComparenvarchar(50),@ValueInTableint,@Resultint out)ASDECLARE @SQLNVARCHAR(1000)DECLARE @Param NVARCHAR(500)SET @SQL = N'SELECT @result = COUNT(*) FROM [' + @TableToCheck + ']' +'WHERE [' + @ColumnToCompare + '] = @ValueInTable ANDApplicationID = @ApplicationID'SET @Param = N'@result int out, @ValueInTable int, @ApplicationIDint'EXECUTE sp_executesql @SQL, @Param, @result out, @ValueInTable,@ApplicationIDI get the same error message about only being able to execute functionsand extended stored procedures in a user defined function.Does anyone have any ideas as to how I can dynamically execute thisquery? The reason I say dynamic is I need this same comparison forabout 25 different tables. Thanks!

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.

Getdate() In User Defined Function
Hi,

It is possible to use getdate() in userdefined function. If so, how to do the same ?

The following code throws error :

create function function1
return varchar
DECLARE @currYYMM VARCHAR(20)
SET @currYYMM = convert(char(4),getdate(),12)
// Here it says the error 'getdate' can't be used inside functions
...............

User Defined Function Obsolete
Hi,

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:

Thx

User Defined Function Problem
Hi,
While i execute the followgin code. it gives error. Please resolve it as while calling the function i want to use getdate() or any other dynamic variable or any select such as

select title from SalesByStore( select admission_Dte from addmission )

It gives error.

--------------------------------------------------------------------------
use pubs
go

createFUNCTION SalesByStore (@storeid datetime)
RETURNS TABLE

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

Pam

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

Calling User-defined Function Without 'dbo.' -- Possible?
