Calling Managed CLR Procedure From Inside User Defined Function -- How To ?
May 15, 2008
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

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.

Hi all,
I'm attempting to write an aggregate function in C++ to compare performance with the equivalent function in C#.
However, I'm having problems getting SQL Server to see the function in the assembly. It allows me to load the assembly into the database, but I can't see the type in it.
Here's my code:
// CPPTest.h
#pragma once
using namespace System;
using namespace Microsoft::SqlServer::Server;
using namespace System::Data::SqlTypes;
using namespace System::Data::SqlClient;
namespace CPPTest {
[Serializable]
[Microsoft::SqlServer::Server::SqlUserDefinedAggregate(
Format::Native,
Name="AGG_CPP_OR")]
public ref struct AGG_CPP_OR
{
public:
void Init();
void Accumulate(SqlInt32 Value);
void Merge(AGG_CPP_OR^ Group);
SqlInt32 Terminate();
private:
SqlInt32 m_accum;
};
}
// CPPTest.cpp
#include "stdafx.h"
#include "CPPTest.h"
void CPPTest::AGG_CPP_OR::Init()
{
m_accum = 0;
}
void CPPTest::AGG_CPP_OR::Accumulate(SqlInt32 Value)
{
m_accum = m_accum | Value;
}
void CPPTest::AGG_CPP_OR::Merge(CPPTest::AGG_CPP_OR^ Group)
{
m_accum = m_accum | Group->m_accum;
}
SqlInt32 CPPTest::AGG_CPP_OR::Terminate()
{
return m_accum;
}
Compile it with /clr:safe option and it can be loaded as an assembly into SQL Server 2005 (9.0.1399), but the AGG_CPP_OR type is not seen as an aggregate function. I've also tried implementing IBinarySerialize and setting Format to Format::UserDefined (and putting in MaxByteSize) but it makes no difference.
Does anyone know what I'm missing here?
Many thanks,

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!

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!

Hi,I'm tring to call a stored procedure i'v made from a DNN module, via .net control.When I try to execute this sql statement: EXEC my_proc_name 'prm_1', 'prm_2', ... the system displays this error: Could not find stored procedure ''. (including the trailings [".] chars :)I've tried to run the EXEC statement from SqlServerManagement Studio, and seems to works fine, but sometimes it displays the same error. So i've added the dbname and dbowner as prefix to my procedure name in the exec statement and then in SqlSrv ManStudio ALWAYS works, but in dnn it NEVER worked... Why? I think it could be a db permission problem but i'm not able to fix this trouble, since i'm not a db specialist and i don't know which contraint could give this problem. Also i've set to the ASPNET user the execute permissions for my procedure... nothing changes :( Shoud someone could help me? Note that I'm using a SqlDataSource object running the statement with the select() method (and by setting the appropriate SelectCommandType = SqlDataSourceCommandType.StoredProcedure ) and I'm using the 2005 sql server express Thank in advance,(/d

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:
Error at Load Orderline [OLE DB Command [15171]]: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Syntax error, permission violation, or other nonspecific error".
Any assistance would be greatly appreciated.
Thanks

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 .

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

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.

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!

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)

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 create the following UDF just for learning purposes and I cannot seem to get it to return a value.
Stored Procedure
REATE PROCEDURE usp_GetXSection
@fWidth float,
@fHeight float,
@fResult float OUTPUT
AS
BEGIN
set @fResult = [dbo].[XSECTION](@fWidth, @fHeight)
END
GO
Ane the following UDF
CREATE FUNCTION XSECTION
(@Width float, @Height float)
RETURNS float
AS
BEGIN
RETURN (@Width * @Height)
END
I call it using ADO in a c++ application, but all returns empty
Any ideas? C++ code to follow.
Mike B
void CFormTemplateSetup::OnCalculate()
{
_CommandPtr pCmd(__uuidof(Command));
_ParameterPtr pWidth(__uuidof(Parameter));
_ParameterPtr pHeight(__uuidof(Parameter));
_ParameterPtr pResult(__uuidof(Parameter));
try
{
pCmd->ActiveConnection = GetDocument()->GetConnection();
pCmd->CommandText = _T("usp_GetXSection");
pCmd->CommandType = adCmdStoredProc;
_variant_t vWidth, vHeight;
vWidth.vt = VT_R4;
vHeight.vt = VT_R4;
vWidth.fltVal = 10;
vHeight.fltVal = 10;
pWidth = pCmd->CreateParameter(_T("@fWidth"), adInteger, adParamInput, sizeof(int), vWidth);
pHeight = pCmd->CreateParameter(_T("@fHeight"), adInteger, adParamInput, sizeof(int), vHeight);
pResult = pCmd->CreateParameter(_T("@fResult"), adDouble, adParamOutput, sizeof(float), vtMissing);
pCmd->Parameters->Append(pWidth);
pCmd->Parameters->Append(pHeight);
pCmd->Parameters->Append(pResult);
_variant_t vResult = pResult->Value;
float fArea = pResult->Value.fltVal;
CString csArea;
csArea.Format("Area = %d", fArea);
::AfxMessageBox(csArea);
}
catch(_com_error& e)
{
::AfxMessageBox(e.Description());
}
}

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!
