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'
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?
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 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).
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:
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.
I 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??
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.
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

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
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.
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.
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!!!
...we understand that perhaps some xp's might come with the product, but for sp's that we author ourselves, are they two different things in 2005, and if so, why would one be chosen over the other?
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?
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 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????
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.
I could identify the last or all stored procedure, which was performed on a database, +/- something similar to what the profile of sql server identifies as below ?
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:
I copied this set of code from a tutorial article that says "@@servername". My Sql Server is SQLEXPRESS, so I put @@.SQLEXPRESS or @@SQLEXPRESS in the code of scBCPcLabResults.sql. I do not know why I got an error {Must declare the scalar variable "@@"} or {Must declare the scalar variable "@@SQLEXPRESS"}!!!??? Please help and advise me how to solve this problem.
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
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
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)
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?
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.
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.
