Only Functions And Extended Stored Procedures Can Be Executed From Within A Function.

Jun 7, 2006

Hi, l've created an function [GSM].[KPIAging], and test it in studio by substitule declare value, i.e.
DECLARE @sCellName VARCHAR(8)
DECLARE @dDate DATETIME
SET @sCellName = "CELL1M_1"
SET @dDate = CAST('06/Jun/2006' AS DATETIME)

EXEC GSM.KPIAging @sCellName, 'CSSR', @dDate

It work fine and return the desired result, but when l used this function in SQL,
SELECT DATEKEY, CELLREGIONKEY, CELL_NAME, CELL_ID, CSSR, GSM.KPIAging(Cell_Name, 'CSSR', @dDate)
FROM GSM.GSMCellDaily_vw
WHERE CSSR BETWEEN 0 AND 85
AND FULLDATE = @dDate
AND CM_SERV > 30
AND (TCH_TRAFFIC > 2 AND TCH_SEIZURES_ATTS > 30)

I got the following error, i.e.
Msg 557, Level 16, State 2, Line 19Only functions and extended stored procedures can be executed from within a function.
Does anyone have any idea on this, and what's the workaround for this?

Thanks you!

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:

The SQL2008R2 server is new. What can I look for?

Here's the code for the function:

Using EXECUTE Statements Calling An Extended Stored Procedures From Function..

Apr 29, 2004

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..

How Stored Procedures Are Executed

Apr 20, 2007

I was wondering the way in which stored procedures are executed.
For example if I had a stored procedure (A) that executed a sub stored procedure (B).
And two different users where to execute the Stored procedure at the same time what would happen.
Would the second user have to wait while the first user had finished (A and B), dose each user get a copy of the stored procedure or can one user be running stored procedure (B) whilst the other is running stored procedure (A).

Extended Stored Procedures

Oct 12, 1999

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.

Access To Extended Stored Procedures

Jul 18, 2007

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

Extended Stored Procedures DB-Lib Alternative

Jul 20, 2005

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.

Credentials And Extended Stored Procedures

Jun 11, 2007

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?

Creating Extended Stored Procedures In C Sharp ?

Apr 26, 2004

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.

Disabling Extended Stored Procedures For Security

Jun 29, 2007

Our 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?

Extended Stored Procedures -&> Loading Linked Files

Feb 11, 2004

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?

Hi all,

I tried to create a CSV file using Bulk Copy Program (BCP) and Stored Procedures: BCP executed from T-SQL using xp_cmdshell. I have the following sql code executed in my SQL Server Management Studio Express and error message:


--scBCPcLabResults.sql--

declare @sql varchar(8000)

Extended Stored Procedure Problem (srv_describe Function)...

Jul 20, 2005

Hello all,I have spend quite some time now but don't manage tofind out how to have the srv_describe function workingproperly for target NUMERIC(x,x) and NUMERIC types.Already tried several alternatives like e.g.// ...PVOID pvdata1;strcpy((char*)pvdata1, "12345.6789");wsprintf(colname, "Score");srv_describe(srvproc, 1 /* column #1 */, colname /* column name */, SRV_NULLTERM /* column name ending */, SRVNUMERIC, (DBINT)sizeof(DBNUMERIC), SRVNUMERIC, (DBINT)sizeof(DBNUMERIC), pvdata1);srv_setcoldata(srvproc, 1, pvdata1);srv_setcollen (srvproc, 1, strlen((char*)pvdata1));// ...but obviously does not work, I get an empty resultset.I could only manage by converting the numeric valueto string from C and then sending only strings but theSQL side expects actually a number(x,x) and is a customer, in which case, I would never propose to be casting thething from TSQL.Any ideas how to do it? The documentation and examples isquite limited in this area.Thanks in advance,Best Regards,Giovanni

Ms Sql Stored Procedures And Functions

 Hi allTrying to figure out what you use ms sql functions for. I understand stored procedures and how to create them. the question is what is the real purpose of a ms sql function considering everything i have read so far makes me think that there is no valid use for them. You can do almost everything that a function does but in a stored procedure. If somebody can give me a good examplle of a sql function i would appreciate it very much.thanks

Stored Procedures And Functions

Sep 9, 2004

I hope I didnt POST in the wrong group. If I did sorry. Anyhoo, on to my question. I have searched the forums and didnt quite find what I was looking for so here goes..
I have create a function that is supposed to return the "SCOPE_IDENTITY" from a stored procedure that updates the database. I'm kinda lost as to how to get the SCOPE_IDENTITY into the function.
I have the following line in the function:

Dim retcode As Integer = cmd.Parameters.Add("@retcode", SqlDbType.Int).Direction = ParameterDirection.ReturnValue
...
cmd.ExecuteReader(CommandBehavior.CloseConnection)

and the following in the stored procedure

@retcode int=NULL OUTPUT
....
SELECT @retcode =SCOPE_IDENTITY()
RETURN @retcode

If I run the stored procedure by itself I get
@retcode = 135
@RETURN_VALUE = 135
So i know the stored procedure works but how do I get that return value into a asp.net function?

Stored Procedures And Functions

Apr 30, 2008



I have the following case.

I have a linked server and I want to execute SQL statements on that linked server which contains millions of records. so I decided to use SELECT * from OPENQUERY(RmtSrv,'SELECT * FROM RmtTbl WHERE Col = ' + @ColValue) but Unforetunatly the query is not succeeded because the OpenQuery doesn't accept parameters.

I used Scalar valued functions and built the query dynamically, but the Scalar valued functions doesn't execute dynamic SQL


ET @LinkedServerName = 'RmtSrv'

SET @RemoteTable= 'RmtTbl'

SET @Query = 'SELECT * FROM OPENQUERY({0}, ''SELECT Col1 FROM {1} WHERE Col2 = ''''{2}'''''') '



SET @Query = REPLACE(@Query, '{0}', @LinkedServerName)

SET @Query = REPLACE(@Query, '{1}', @RemoteTable)

SET @Query = REPLACE(@Query, '{2}', @Col2Value)

EXEC(@Query)

the above code is not executed because the functions doesn't execute dynamic queries.

I deleted the function above and wrote a Stored Procedure with the same code. but I can't query the stored procedure

SELECT GetColValue(Table1.Col1)
FROM Table1.


where the GetColValue is the name of the stored procedure.

Do you have any solution that I can use to perform Remote SQL statements considering the performancewise and the code shall be centralized in certain stored procedures and functions

the Remote server contains millions of records and I will use it from tens of applications and databases.

Using User Functions In Stored Procedures

Feb 1, 2005

Hi There,
I've written an inline table-valued function in SQL such as the following:

ALTER FUNCTION dbo.GetCityByID( @CityID int)
RETURNS TABLE
AS
RETURN(
SELECT
Name,
Url
FROM Cities
WHERE (CityID = @CityID) )

suppose that Cities table includes three fields (CityID, Name, Url).

By the way I wrote a store procedure as follow:

ALTER PROCEDURE MyProcedure ( @MyID int)
AS
SELECT
CountryID,
OriginCityID,
DestCityID
FROM
MyTable
WHERE (MyID = @MyID)

The OriginCityID and DestCityID are related to CityID in Cities table. I wanna get the name
and url of each city by its ID through this stored procedue by making relation to Cities table.
so I call GetCityByID function in my stored procedure like this:

ALTER PROCEDURE MyProcedure ( @MyID int)
AS
SELECT
CountryID,
dbo.GetCityByID(OriginCityID),
dbo.GetCityByID(DestCityID)
FROM
MyTable
WHERE (MyID = @MyID)

this procedure dosn't work an returns error.

What's your solution for getting information from Cities table for OriginCityID and DestCityID?
Thank you in advance.
