Hi. Does anyone know how to display the results if i execute "xp_fixeddrives, xp_availablemedia and xp_subdirs" commands with VC++ 6.0? I can't obtained the results using Recordset class. Can someone help me? Thank you.

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've written a very simple extended stored proc--little more than what VC++
6.0's ext stored proc wizard generates--set up the xp in the master database,
and eventually want to execute it from a trigger defined on a table in another database...
I've tested the xp in Query Analyzer. If the DB is set to 'master', the xp
runs (exec xp_InputTrigger), no problem. If I change databases and try to run the xp, I get:
Server: Msg 2812, Level 16, State 62, Line 1
Could not find stored procedure 'xp_InputTrigger'.
Keying "exec master.xp_InputTrigger", also fails: Could not find stored procedure 'master.xp_InputTrigger'.
I've checked permissions--all seem to be set right. Anyone have any insight
for me here? Many thanks,

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.

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,
Alla
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?
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'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?

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?

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, 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 know that syscomments stores the stored procedures in chunks of 4000 characters. Some of my Stored proc's are >4000 characters.I use a temporary table to stock them after some modifications made to them.How can I execute them one by one, do i need to concatenate one whole stored proc's text in one single line(if yes, how can that be done?) Can variables be dynamically created, assigned values and then destroyed? Please help.

View 3 Replies View RelatedI have a table with a list of stored procedures, I iterate using a Foreach loop which i iterate through an ADO.NET recordset that I created by executing a select SQL statement.
Now my problem is that in the foreach loop i have an execute sql task container which basically just executes these stored procedures using the 'exec ?' statement (i grab the name of each procedure into a variable). However, error trapping seems to be very difficult. I just figured out how to get a ReturnCode from the execute statement, but apparently I have to use it outside the Execute SQL task ....prolly use an IF condition to see if its not 0....but how do I go about doing this?
Also, I want to error trap if a stored procedure doesnt execute because of some error, how could i possibly handle an error like that? I dont want the foreach iteration to stop on an error because a stored procedure wasnt called either, but currently it does stop the entire package.
Thoughts anyone?
I am having trouble executing a series of 4 stored procedures from VB. The connection code connects and the first 3 stored procedures run through, although the 4th procedure stops running mid execution. No errors are reported to VB. When I run the series of procedures in the SQL Server Query Analyzer everything completes as it should. Anyone have any suggestions on what could be the problem?
View 1 Replies View RelatedHey guys,
I have found out that we can execute multiple queries and receive multiple resultsets in a SqlDataReader by executing the queries with ";" separators,
However, what if we wanted to execute two sqlcommand storedprocedures? are there any other way rather than placing "Execute sp1;Execute sp2" in the command text?
I would like to do it in a way whereby I can pass in two storedprocedures with parameters binding capability rather than execute sp1(param1, param2);execute sp2(param1, param2, param3)
Hope to get some suggestions and advice from you guys,
Thank you very much in advance.
