Stored Procedure Migration And Security
Apr 30, 2008
I have an ASP page which is supposed to populate a dropdown based on values returned from a stored procedure. This ASP page is working on our old server. I recently moved all the pages, code, ect over to our new server including migrated to SQL Server 2005 (from 2000 I think), as you can tell, somthing broke...
I assume this is security related however, all the relevant security is set correctly as far as I can tell. I am granting "Execute" access for the stored procedure and "Select" access for all the referenced tables. Am I missing something? Is there another security setting which needs to be set?

I am writing a number of data migration scripts, like the (simplified version) below
Code:
INSERT INTO newDatabase.dbo.DaDestinationTable(col1, col2, col3)
SELECT col1,
col27,
col13
FROM OldDatabase.dbo.DaSourceTable
There are no validation rules defined in the database (don't ask why), only in the program code. Because of the absence of validations in the database, the data migration scripts could violate business rules (NOT NULL, FK violations, domain values in a column, ...).
A solution could be that both the program and the data migration call the same stored procedure to insert records in the destination table, so the validation rules must only be defined in one place (the stored procedure).
I have never used stored procedures in a "set-based" situation. Is this even possible? The only solution I see is to call those sp's in a loop (WHILE or CURSOR). Something like
Code:
SET @my_id = -1
SELECT @my_id = MIN(id)
FROM OldDatabase.dbo.DaSourceTable
WHERE id > @my_id
WHILE @my_id IS NOT NULL
[Code] ....
For each record, the table OldDatabase.dbo.DaSourceTable is hit twice, once to get the next id (@my_id), once to get the column values. I could combine both with one SELECT script by using ROW_NUMBER(), but I doubt that that will perform faster.
I only work set-based, I have barely ever used a WHILE loop, let alone a CURSOR. What the consequences will be on performance. There are millions of records that have to be migrated.
I was thinking of CROSS APPLY, but you can't use that in combination with a SP.

Is it a safe way to use a paramter (which fetch values from querystring) in the "where-part" of my stored procedure? Or is it an securityrisk because I dont know what the user is writing in the url-field?
I got the following sqldatasource which grab the value (from querystring) into the my parameter.
<asp:SqlDataSource ID="SQLDataSource"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
runat="server"
SelectCommand="My_StoredProcedure"
SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:QueryStringParameter QueryStringField="Myparameter" Name="City" Type="string" />
</SelectParameters>
</asp:SqlDataSource>

Hi all,
this should be a easy question, but I can't really seem to find anything on it...
Here's the scenerio:
n-tier web app, with asp/iis/sql... All database calls are done via stored procedures with the same user (lets call the user: webuser)
webuser has NO access to the db in question, but it is granted EXEC on all stored procedures.
My question is, when a user tells the web app to say delete a record, the application server (iis) makes a call to the database with the webuser security cred's... It says execute the delete stored proc.
webuser has the ability to do this, so it happens. However, in what context (this may not be the right word) does the stored procedure execute?
ie: which user does the stored proc exeucte as. It can't be webuser can it? Because webuser does not have access to the base tables.
Does the stored proc execute as the user that created it?
I'm confused...
thx all!

Hi,
I have a Stored Procedure in one database that grabs data from another database. I don't want the user to be able to read data from the tables that the stored procedure Selects from but I would like the user to be able to run the stored procedure. Pretty standard request I think.
What I have done is to give the user in question a login then assigned them the Execute Permissions on the stored procedure. Unfortunately they are still unable to run the stored procedure from my web app. I have "allow anonymous access" turned on but I am still getting an error when the user tries to execute the stored procedure.
Am I missing something here or could there be a bigger issue?
Thanks,
Patrick

Hi,
I created a CLR stored procedure, and added a web service reference, am using the generated proxy class
to call the web service, currently am facing the following security issues. I think am missing
something, what are the possible patterns to call a web service from the CLR Stored procedure.
Thank you

Does anyone know how you can distribute Stored Procedures that work with a third party application but keep the contents / code of those Stored Procedures from being viewed and edited by the end users who have purchased the application as well as own and operate the SQL Server??

Hi,I have a .NET application that connects to a SQL 2000 database usingtrusted security. It eventually calls a stored procedure that receives3 parameters - nothing special.If I simply change the connection string to use a valid Userid andPassword it still connects to the DB w/o problems but when it executesthe SP I get the following:System.Data.SqlClient.SqlException: Invalid length parameter passed tothe substring function.I change nothing but the login. Same store procedure, same parameters.Any ideas?

Hi all .
I am going to consult you about a security concept .
In my database I have a set of tables (eg. City , Country , ...)
and I have a corresponding View for each Table (eg. V_City , V_Country , ...)
and There are a set of Add/Delete/Update/List stored procedures for each object , the user which logs on to database has only EXECUTE Privilege on defined stored procedures and does not have any kind of access to any other object in database , In your opinion , Can Inserting into/Updating Views instead of Inserting into/Updating Tables cause any problem?and Is this model help improve security? Not that I access SQL Server Database from a .Net App.
Thanks 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.

we recently migrated from our in-house domain to the Enterprise domain. Everything went smooth except for the fact that I can no longer accept my dBs using my SA or my domain admin account. There is only 1 account I can get into the management studio with but it has no admin privileges, so I can't make any password changes or add accounts. I don't have a test environment so kind of hesitant to experiment with our production system.

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

Hi all,
I have 2 sets of sql code in my SQL Server Management Stidio Express (SSMSE):
(1) /////--spTopSixAnalytes.sql--///
USE ssmsExpressDB
GO
CREATE Procedure [dbo].[spTopSixAnalytes]
AS
SET ROWCOUNT 6
SELECT Labtests.Result AS TopSixAnalytes, LabTests.Unit, LabTests.AnalyteName
FROM LabTests
ORDER BY LabTests.Result DESC
GO
(2) /////--spTopSixAnalytesEXEC.sql--//////////////
USE ssmsExpressDB
GO
EXEC spTopSixAnalytes
GO
I executed them and got the following results in SSMSE:
TopSixAnalytes Unit AnalyteName

2 220.30 ug/Kg Acetone
3 211.90 ug/Kg Acetone
4 140.30 ug/L Acetone
5 120.70 ug/L Acetone
6 90.70 ug/L Acetone
/////////////////////////////////////////////////////////////////////////////////////////////
Now, I try to use this Stored Procedure in my ADO.NET-VB 2005 Express programming:
//////////////////--spTopSixAnalytes.vb--///////////
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim sqlDataAdapter As SqlDataAdapter = New SqlDataAdaptor("[spTopSixAnalytes]", sqlConnection)
sqlDataAdapter.SelectCommand.Command.Type = CommandType.StoredProcedure
'Pass the name of the DataSet through the overloaded contructor
'of the DataSet class.
Dim dataSet As DataSet ("ssmsExpressDB")
sqlConnection.Open()
sqlDataAdapter.Fill(DataSet)
sqlConnection.Close()

End Class
///////////////////////////////////////////////////////////////////////////////////////////
I executed the above code and I got the following 4 errors:
Error #1: Type 'SqlConnection' is not defined (in Form1.vb)

Error #3: Array bounds cannot appear in type specifiers (in Form1.vb)
Error #4: 'DataSet' is not a type and cannot be used as an expression (in Form1)
Please help and advise.
Thanks in advance,
Scott Chang
More Information for you to know:
I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly.
I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.

I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?
CREATE PROCEDURE [dbo].[runDMQ3_2014LDLComplete]
@QQ_YYYY char(7),
@YYYYQQ char(8)
AS
begin
SET NOCOUNT ON;
select [provider group],provider, NPI, [01-Total Patients with DM], [02-Total DM Patients with LDL],

I have a stored procedure that calls a msdb stored procedure internally. I granted the login execute rights on the outer sproc but it still vomits when it tries to execute the inner. Says I don't have the privileges, which makes sense.
How can I grant permissions to a login to execute msdb.dbo.sp_update_schedule()? Or is there a way I can impersonate the sysadmin user for the call by using Execute As sysadmin some how?

Has anyone encountered cases in which a proc executed by DTS has the following behavior:
1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio
2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio
What could explain this?
Obviously,
All three scenarios are executed against the same database and hit the exact same tables and indices.
Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).
The DTS execution effectively never finishes even after many hours (10+)
The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query)
The Update ad-hoc query will finish in 2 minutes

Hi all,
I am trying to debug stored procedure using visual studio. I right click on connection and checked 'Allow SQL/CLR debugging' .. the store procedure is not local and is on sql server.
Whenever I tried to right click stored procedure and select step into store procedure> i get following error
"User 'Unknown user' could not execute stored procedure 'master.dbo.sp_enable_sql_debug' on SQL server XXXXX. Click Help for more information"
I am not sure what needs to be done on sql server side
We tried to search for sp_enable_sql_debug but I could not find this stored procedure under master.
Some web page I came accross says that "I must have an administratorial rights to debug" but I am not sure what does that mean?
Please advise..
Thank You

First off I am a rookie at Sql Server. Ok let's give this a try. Mycompany has bought a new software package called Viewpoint. It's OnSql Server and written in VP. We do not have access to the code.There is a option in the software package called "ApplicationSecurity". When this is clicked you are unable to access the ViewpointDatabase from an outside application. Since I can't get to the code Ihave no idea how this feature works.I would like to keep the "Application Securty" ON so no one can accessthe Viewpoint Database from an outside application but I would like towrite my own outside application where I can access the Viewpointapplication tables while the Application Security in ON. Does anyoneknow what I am talking about? I know it is not very clear and I amworking with limited information, but any help would be appreciated.Thanks
