Is it possible to create an extended stored procedure in C Sharp.
This is for Sql Server 2000.
Books online mentions that you have to use c / c++ to create an extended stored procedure.
However have Microsoft added any support so that the same thing can be done through a simpler language like C Sharp.
Thanks,
Alok.
i have created the folowing function but keep geting an error.
Only functions and extended stored procedures can be executed from within a function.
Why am i getting this error!
Create Function myDateAdd
(@buildd nvarchar(4), @avdate as nvarchar(25))
Returns nvarchar(25)
as
Begin
declare @ret nvarchar(25)
declare @sqlval as nvarchar(3000)
set @sqlval = 'select ''@ret'' = max(realday) from (
select top '+ @buildd +' realday from v_caltable where realday >= '''+ @avdate +''' and prod = 1 )a'
execute sp_executesql @sqlval
return @ret
end
I'm trying to execute an exetended stored procedure from a trigger. The scenario is this: when an input occurs on a table, my trigger is fired, the extended stopred procedure is to be run, and VB app is to be notified that there is new input to process.
Problem is, I can't seem to get the XP to run. I have written a minimal DLL
with VC++ 6, has nothing but the required __GetXpVersion function and the
trigger function, as:
__declspec(dllexport) SRVRETCODE xp_InputAlarm(SRV_PROC *pSrvProc)
{ return XP_NOERROR; }
__declspec(dllexport) ULONG __GetXpVersion()
{ return ODS_VERSION; }
Pretty simple. I have defined the XP in the master database, set the properties point to the DLL. Believe everything is set up properly. However,
when an input occurs, a run-time error is generated on the XP. Attempting to execute it in Query Analyzer gives this error:
"Cannot find the function xp_InputAlarm in the library D:CustomMedInstaCert SourceInputAlarmInputAlaInputAlarm.dll. Reason: 127(The specified procedure could not be found.)."
Which I think means it can't find the proper entry point (xp_InputAlarm) in the DLL. Any help would be greatly appreciated.

Is there any way I can create an SQL script on any extended stored procedures? I need to see what they do. I looked in books online, but it didn't help. Thanks.
View 3 Replies View RelatedI am working with Visual Basic and SQL Server 2000. I am looking to convert some of the VB into extended stored procedures, yet everything I've been reading has said that xp's can only be written in C or C++. Is this true??
Thanks.

Howdy,
I'm trying to call XP_CMDSHELL from a stored procedure that's not in the Master db. How do I call XP_CMDSHELL? I've tried "Use Master" but I get an error telling me that I can't use "USE" inside of a stored procedure.
Thanks!
I would like to know if the the DLL`s one can build with VB5/6 can be used to construct Extended Stored Procedures in MS SQLServer 6.5? If so, how does one do this. All the reference material I`ve come across is for C
Thanks in Advance - Ralph

Hi,
How can I remove access to extended (xp_) stored procedures?
Is there any revoke on <stored_procedure_name> ... command? How can I generate a script of all users who have execute privileges for these procedures? Also, is there any way of restricting (instead of removing) access to those procedures?
Any help will be greatly appreciated!!!
Thanks,

Hi all,
In one of my UDF I use the following functions:
.....
and len(@int_date) = 4
and isnumeric(substring(@int_date,5,6)) = 1
when I use the function I get
Only functions and extended stored procedures can be executed from within a function.
Yes, when I comment the two lines the function works fine.
Ehm.... why can't I use these functions in my function ?
Thanks: Peter
Since DBlib is no longer the suggested method for connecting back tosql server from an Extended Stored Procedure, has anyone built anyextended stored procedures that use other connection methods likeOLEDB? Has anyone seen links to any sample extended stored proceduresthat use something other than db-lib? In particular I am interestedin something that connects back to the database as the user whoinvoked the extended stored procedure. I haven't had much luckfinding any.Also, is there an alternative for the bcp api that is a little morecurrent and has support for newer datatypes like bigint? We currentlyuse the bcp api from an extended stored procdure written in C++, butnow need to add bigint support which the bcp api doesn't have.Thanks for any advice.

The Extended Stored Procedures (Written in C++ unmanaged code) are supported in SQL Server 2005????
Thanks
I have a database script that uses the extended stored procedures sp_OACreate and sp_OCMethod to execute an .exe file. The .exe file is located on the same machine as the SQL Server. At this time it does nothing but log the name of the user calling it.
When I execute the script from Management Studio (logged in as myself) the user being logged as the caller of the .exe is still NT AUTHORITYSYSTEM. I don't know why NT AUTHORITYSYSTEM is the caller, cause the SQL Server service runs under another domain account.
I have tried playing around with EXECUTE AS USER but no matter what, the caller of the .exe is always logged as NT AUTHORITYSYSTEM.
Are there any way I can pass my credentials to the executable that I am calling from the T-SQL script?
I'm trying to pass parameters to an extended stored procedure, to noavail. I would like to pass two integers to the dll and I have thefollowing three snippets:1. The C++ portion of the dll:....declspec(dllexport) int myAddNumbers(int m, int n)....2. The creation of the extended stored procedure:EXEC sp_addextendedproc myAddNumbers , 'foodll.dll';3. The usage:create function TestFunction()returns integerasbegindeclare @rc integerexec @rc = myAddNumbersreturn (@rc)endHow do any of the above three things need to be modified in order tomake this work?Thanks!!!

View 1 Replies View RelatedOur security team wants us to disable access to (or drop) all of the built-in extended stored procedures in MSDE 2000 as they feel it is a vulnerability. Where can I find out which extended procs are safe to disable or how we can disable them during install time? Or, is the security team being too cautious and we should just tell them to leave these intact?

Hi All,
Is there any way that I can create a dll file for Extended stored procedure(SQL server) in C# ?
I an able to create that in VC++. in VC++ there is DLLMain which serve as entry point and a paramter can be passed to it using Extended stored procedure. But since C# does not have any such entry point. Hence is there any way that I can achieve this?
Any pointers to this will be highly appreciated.
Thanks

You know this sample ODS dll project:
$80oolsdevtoolssamplesodsxp_hello
I need to find a template like this in Visual Basic.
On this site I read through the xp_Encrypt project which was developed in VB. I did not see source code or a downloadable project file.
My searching on the internet hasn't yielded any practicle results, all examples are either how to use an extended stored procedure or are a MSVC++ project.
Anyone find VB related resources, anywhere? Books, TV, magazines????
Hello everybody
I actually wrote a stored procedure (in xp_wrapper.dll) that is using a dll (original.dll) which uses a license file (no file extension).... clear? :)
Anyway.
All the required files are placed in the BINN dir of the server.
The problem is now, that original.dll can't find it's license file. It seems, that this file was not load by SQL Server.
How can I load this file into SQL Server's heap?
Yours
Mike
What is the overhead of using extended stored procedures?I created a table with 500,000 rows.1) I ran a select on two columns and it runs in about 5 seconds.2) I ran a select on one column and called an UDF (it returns aconstant string) and it takes 10 seconds.3) I ran a select on one column and called a UDF that calls an extendedstored procedure that returns a string and it takes 65 seconds.I also tried running test 3 with 4 concurrent clients and each clienttakes about 120 seconds.

Hi,
web searches give no end of how extended stored procedures can only be written in C++ ( or maybe vb also) .
And that extended stored procedures should be abandonded in favour of CLR framework procedures.
And how most articles explain how to convert ESPs to CLR procedures!!!!!
But I need to pass a non-discript block of binary data, extract pieces of data identified by its offset into the block, data type inferred by offset; into data to be written to the SQL database. These offsets are determinede by mapping (C UNION) to C typedef structures.
This cannot be done by managed code, therefore cannot be done by C++ CLR.
It is also ill suited for C# .
Sounds like a job for C++ extended stored procedure.
But how does one create and deploy an ESP with Visual Studio 2005? All wizards seem to insist on CLR.
Help!?

Hi, all
I'm using Sql server 2000
I want to make select statement dynamically and return table using function.
in sp, I've done this but, in function I don't know how to do so.
(I have to create as function since our existing API..)
Following is my tials...
1.
alter Function fnTest
( @fromTime datetime, @toTime datetime)
RETURNS Table
AS
RETURN Exec spTest @from, @to
GO
Yes, it give syntax error..
2. So, I found the following
From Sql Server Books Online, Remark section of CREATE FUNCTION page of Transact-SQL Reference , it says following..
"The following statements are allowed in the body of a multi-statement function. Statements not in this list are not allowed in the body of a function: "
.....
* EXECUTE statements calling an extended stored procedures.
So, I tried.
alter Function fnTest
( @fromTime datetime, @toTime datetime)
RETURNS Table
AS
RETURN Exec master..xp_msver
GO
It doesn't work... syntax err...
Here I have quick question.. How to execute statements calling an extended stored procedures. any examples?
Now, I'm stuck.. how can I create dynamic select statement using function?
I want to know if it's possible or not..
I have this function called fn_GetTimedKey() when I run it in my SQL2005 environment it works fine.
When I run it in my SQL2008R2 environment I get the error:
Only functions and some extended stored procedures can be executed from within a function.
The SQL2008R2 server is new. What can I look for?
Here's the code for the function:
BEGIN
DECLARE @v_Key CHAR(12)
EXEC master..xp_usg_gettimedkey_VAL @v_Key OUTPUT
RETURN @v_Key
END
I want to create a replication on PUBS database between the servers "DENVER" and "VANCOUVER". I created a publication on "DENVER" using SALES table of PUBS database. In the properties of publication, I selected all the options of "Subscription creation and synchronization" under "Subscription options".
Then I created a pull subscription on "VANCOUVER" using PUBS database. As data of SALES table is same in both servers and also I want to use subscribers schema and data, I chose the option "No, the subscriber already has the schema and data" for initializing subscription. Now the problem is when I do updations in sales table, subscription is returning error "Could not find stored procedure 'sp_MSupd_sales'". I was found that subscription is not creating any of the stored procedure that is needed for subscribing from publication. Please help me to solve this problem.
Thanking You all,

I just installed sql server 2005 on my machine. I've been using Access for some time and have created my stored procedures easily in it. However, this sql server 2005 is so complicated. In Access, all I had to do was "Create a New Query", write my sql statement, name and save it. However, I am having so much trouble with this sql server. For example, when I create a stored procedure in sql server, it has a .sql extension. I am assuming the stored procedure is a file. However, after saving it, I expand my database, expand programmability, and expand stored procedures, yet my new stored procedure is not there. It's placed in a file called projects. I need to access this stored procedure from code, but in visual studio, I get an error message, "Cannot find stored procedure sp_Roster". Here is the code I used to access my stored procedure from vb.net. I thought it would work but it didntDim comm As New SqlCommandDim strsql As StringDim strconn As String strsql = "sp_Roster" strconn = "server=Home; user=sa; pwd=juwar74; database=Book;" With comm .Connection = New SqlConnection(strconn) .CommandText = strsql .CommandType = CommandType.StoredProcedure With .Parameters.Add("TeacherID", SqlDbType.Char) .Value = "DawsMark@aol.com" End With With .Parameters.Add("ClassID", SqlDbType.Int) .Value = CInt(classid) End With With .Parameters.Add("sID", SqlDbType.Int) .Value = ssID End With With .Parameters.Add("sLastName", SqlDbType.Char) .Value = lastname End With With .Parameters.Add("sFirstName", SqlDbType.Char) .Value = firstname End With With .Parameters.Add("sMiddleName", SqlDbType.Char) .Value = middlename End With With .Parameters.Add("Student", SqlDbType.Char) .Value = fullname End With With .Parameters.Add("Password", SqlDbType.Char) .Value = password End With .Connection.Open() .ExecuteNonQuery() With comm.Connection If .State = ConnectionState.Open Then .Close() End If End With End With Here is my procedure that I created and that was saved as sp_Roster.sql in sql server CREATE PROCEDURE sp_Roster ASBEGIN SET NOCOUNT ON; -- Insert statements for procedure here INSERT INTO Roster (TeacherID, ClassID, sID, sLastName, sFirstName, sMiddleName, Student, Password) VALUES (@TeacherID, @ClassID, @sID, @sLastName, @sFirstName, @sMiddleName, @Student, @Password)ENDGO Why isn't ado.net finding it in sql server. Is the sqlstr correct?

I am creating a database application that is accessed through a .NET front end.
What I want to do is run a SQL script that will create my DB, create my indexes and enforce my constraints (all of which I have done) but I also want to create my stored procedures in the same script also.
When I merge all my stored procedures (about 16) into one file and run it in SQL Query Analyzer I get multiple errors but the one that is coursing me the most bother is
‘Server: Msg 156, Level 15, State 1, Procedure procedureName, Line 134
Incorrect syntax near the keyword 'procedure'.’
What does this mean and why can’t I run more than once Stored Procedure at once?
Many thanks
