Context Of Procedure Call That Results In Trigger
May 8, 2008
If an application makes a connection under a given user, performs the following:
- calls a stored procedure which performs an insert,
- the insert causes a trigger to be fired
- the trigger causes a sql statement to execute against a different
database
Questions:
* Does the user who called the procedure, also need permissions to this 2nd database ?
* What security context does this trigger get executed ?
I have a stored procedure that is being called by my .Net application. The user account that makes the connection has execute permission to the procedure. However, the procedure does an insert which causes a trigger to fire. This trigger does a sql statement against a table in a different database, which the user who is calling the procedure, does not have permissions to access. Im getting an exception when I call the procedure, and it basically says there was a permission error with the user accessing this other database.

Hi I am trying to run a dll or exe from a procedure or trigger in the database.
I have tried EXEC master ..xp_cmdshell '\xx empdivConsoleApplication1.exe' and
use master exec dbo.StoredProcedure1
If I run the exe from explorer all is working, but from a trigger or procedure in the database nothing happens only executed successfully.
I loaded the assembly and procedure into the master database
Code Block
CREATE PROCEDURE [dbo].[ClassLibrary3] AS EXTERNAL NAME
[ClassLibrary3].[ClassLibrary3.Class1].[StoredProcedure1]
My C# code:
Code Block
public partial class StoredProcedures
{ [Microsoft.SqlServer.Server.SqlProcedure]
public static void StoredProcedure1()
{ //------first a select to get some data String prosjekter = "";
String connString = @"Data Source=serverOFFICESERVERS;Initial Catalog=WSS_Content;Integrated Security=SSPI";
SqlConnection conn = new SqlConnection(connString);
SqlCommand sqlcmd = new SqlCommand("Select nvarchar3 prosjekt from dbo.AllUserData where tp_listId = @listid", conn);
sqlcmd.Parameters.AddWithValue("@listid", "xxx"); try { conn.Open(); SqlDataReader r = sqlcmd.ExecuteReader();
while (r.Read())
{ prosjekter += "" + r["prosjekt"] + "" + "";
}
r.Close(); conn.Close();
} catch (Exception)
{ conn.Close(); }
//-----write some changes back to a program pocketForm pf = new pocketForm();
try {
pf.LoadFromFile("C:/temp/div/xxx.xpf");
string xmlstring = pf.FormXML;
int id, item, items; id = xmlstring.IndexOf("xxxxx");
item = xmlstring.IndexOf("", id);
items = xmlstring.IndexOf("", item);
xmlstring = xmlstring.Remove(item, items - item);
xmlstring = xmlstring.Insert(item, prosjekter);
pf.FormXML = xmlstring;
pf.StatusModifiedLocally = true;
WebService.Login("http://xxxx.no", "xx", string.Empty, string.Empty);
WebService.Save(pf);
} catch (Exception)
{
}
What am I missing here ? Please answer this as I have tried everything with no success. Regards Ivar

I have a few questions about the following t-sql 2008 r2 sql code listed below that is calling a stored procedure:
DECLARE@return_value int,
@endYear SMALLINT = 2014,
@CustomerID INT = '9999',
@Schedules CHAR(1) = N'C'
EXEC [dbo].[sproom] @endYear
,@CustomerID
,@Schedules
The sql listed above does execute the stored procedure called [dbo].[sproom] successfully and returns all the data all the rows from the stored procedure multiple times. However can you tell me the following:
1. How can I have the stored procedure return distinct rows?
2. I want the stored procedure to return selected columns. I tried using the OUTPUT parameter for some of the columns, but I got the error message, "Procedure or function spHomeroom has too many arguments specified.".
when I change the sql above to:
DECLARE @return_value int,
@endYear SMALLINT = 2014,
@CustomerID INT = '9999',
@Schedules CHAR(1) = N'C',
@CustName varchar(50)
EXEC [dbo].[sproom] @endYear
,@CustomerID
,@Schedules
,@CustName
That is when I get the error message.
A solution might be to change the stored procedure, but I would prefer not to since this is a generic stored procedure that I believe a lot of t-sqls and stored procedures will use.

I'm currently creating a database that will only allow data operations through stored procedures, ie users will not be able to directly modify tables. I'd like to use an Insert trigger which will run in response to a stored procedure that inserts records. The trigger will check business logic and additionally modify records in a couple of other tables. Given that I've disallowed direct access to the tables, will it run or will the security set-up prohibit that?Thanks in advance for any answers.

I am writing a trigger to audit changes to certain columns. In the trigger I
would like to record to the "Audit" table as much information about the
current execution context as possible (current user, login, nt user,
inputbuffer, etc.). I couldn`t find the way to find out what is the
currently executed* stored procedure. @@PROCID returns object id for the
trigger itself. Any help would be highly appreciated as this is an urgent
production environment issue.
regards,
Anatol

I have a c# stored procedure that is being called from a trigger. When I execute it from management studio, it works just fine. But, when I update a record in the table that has the trigger that calls the sp, I get the error "transaction context in use by another session error". I've tried a few of the "fixes" that I found through searching, but so far nothing seems to work. What I've tried so far is...
Removing the transaction from my code
making sure my code is only using 1 connection
setting XACT_ABORT ON
Any other ideas? Thanks.

Every time I call Encrypt by key I get a different result, although I am encrypting the same clear text,using the same authenticator and using the same key.
I tried calling it twice inside one stored procedure and I got two different results.
Declare @Temp varbinary(8000);
Declare @Temp2 varbinary(8000);
set @Temp = EncryptByKey(Key_GUID('MyKey'),@cleartext,1,@Authenticator);
set @Temp2= EncryptByKey(Key_GUID('MyKey'),@cleartext,1,@Authenticator);
Select @Temp,@Temp2;
when executing this stored procedure, the value of @Temp is differnent from the result of @Temp2, and the same thing happens without using an authenticator.
Is there something going behind in the encryption mechanism of SQL server?

I need some help calling a DLL or EXE from a SQL Trigger. I have the trigger set up, except I have no clue how to call a DLL or EXE or if it is even possible. Here is what I have for the Trigger so far:
-- ================================================
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
CREATE TRIGGER CallProgIfParentID
ON Toc
FOR INSERT
AS
IF ((select ins.[ParentID] FROM inserted ins) = '57660')
-- I want to be able to programmatically change '57660' from an ASPX page
EXEC
-- This is where the call function goes
GO
Another question I have is can a trigger be created programmatically using ASPX pages written in VB.NET in VS2003?
Thank you in advance

CLR function has the following few lines which is invoked from Internal Activation Stored Procedure:
SqlCommand command = Connection.CreateCommand();
command.CommandText = "CREATE ASSEMBLY " + """ + AsmName + """ +" AUTHORIZATION [dbo]"+ " FROM " + "'" + regasm.UncPath + "'" + " WITH PERMISSION_SET=SAFE";
command.ExecuteNonQuery();
I am getting the following error:
"Could not impersonate the client during assembly file operation."
The CLR function is invoked from Service Broker internal activation stored procedure.
"SELECT user_name()" returns dbo just before CREATE ASSEMBLY execution.
SqlContext.WindowsIdentity.Name is "NT AUTHORITYSYSTEM" as the Data Engine runs with the LocalSystem account.
How do I create a the necessary security context for "CREATE ASSEMBLY" to succeed ?
Service Broker Queue activation with EXECUTE AS = "SELF", "OWNER", domain account or dbo, all result in the above error. The Service Broker assembly having the internal activation stored procedure is registered "unsafe".
Many Thanks.

I have created a trigger to call a program that is written by our program. The program is basically read the record in the table and write to a text file, then delete the record from the table.
The trigger is a after insert trigger. After we added the trigger, we insert a record to the table. The result is that the record still and did not get deleted. Also, the text file didn't get created either. It seems that it take a long time for the record to be written to the table.
But if we just run the program (a exe file), it can write a text file in the folder and delete the record. the trigger is basically:
USE [Zinter]
GO
/****** Object: Trigger [dbo].[ZinterProcess] Script Date: 04/29/2014 18:34:56 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

Hi,
I have an integration solution that backs into two databases. Database A is custom and Database B is integrated from a COTS product. The manufacturer of B supplies a formal interface as stored procedures (and I intend to honor that contract by limiting my access to B through those stored procs).
Now, I have a search that is going to involve a subselect in the form of the following pseudocode:
select a,b from dbA.user.TableX where exists (select a from dbB.user.TableY)
I am trying to avoid creating 2 temporary cursors in the integration application and doing things in-memory (b/c of performance concerns).
So, my q is:
How can I make this happen within database A?

I have a stored procedure 'ChangeUser' in which there is a call to another stored procedure 'LogChange'. The transaction is started in 'ChangeUser'. and the last statement in the transaction is 'EXEC LogChange @p1, @p2'. My questions is if it would be correct to check in 'LogChange' the following about this transaction: 'IF @@trancount >0 BEGIN Rollback tran' END Else BEGIN Commit END.
Any help on this would be appreciated.

SQL Version:Â SQL2014
PROBLEM: The SQL insert trigger code below is returning incorrect results. In some cases the results returned are from entirely different fields than those specified as the source field in the SET statement. For instance the value returne for the Price_BeforeAdj field does not = 20000000? It returns a NULL. See code below.
OFFENDING CODE:
ALTER TRIGGER [dbo].[xcti_WIPAdjustments_I]
  ON [dbo].[budxcWIPAdjustments]
AFTER INSERT AS
BEGIN
 SET NOCOUNT ON;
  UPDATE budxcWIPAdjustments

I have a SQL2000(sp2) database (ServerA) and a SQL7(sp2) database(ServerB)
From the SQL2000 database I want to call a remote stored procedure on ServerB and store the result set in a table on ServerB.
E,g
insert TableA
exec ServerB...sp_GetStuff
If I try this by making serverB a remote server,
I get the following error message
Server: Msg 18456, Level 14, State 1, Line 1
Login failed for user 'sa'.
If I make ServerB a Linked server, I get the error
Server: Msg 8501, Level 16, State 1, Line 1
MSDTC on server '' is unavailable.
Server: Msg 7391, Level 16, State 1, Line 1
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.
Now the MSDTC on ServerB won't start - It returns error 3221229574 to which the solution seems to be to reinstall MSDTC which looks like a very messy job with registry hacks and also the threat of reformatting the hard drive So I don't want to do this if possible
I really don't want a distibuted transaction anyway so I tried to stop the transaction being promoted using
SET REMOTE_PROC_TRANSACTIONS OFF
But this has no effect
Any ideas would be appreciated"
