My project modules in MS-Access rely heavily on DAO permissions. Now the access front end is being hooked up to a SQL Server 2005 back end, and I'd like to sync the permissions of linked table objects with the corresponding views when they are created/recreated.
I'm vaguely aware there are a substantial number of differences between the the SQL Server and Jet security models. Initially, I'd like to create a lookup table to handle this.
My problem is that I don't seem to be able to find much info on groups and object permissions in the SQL Server security model - perhaps I'm asking the wrong questions.:confused: Can anyone provide a link to a decent site for SQL Server novices?
Running on a SQL 6.5 server, I want to know how can I get a report from Options,Permissions that will list me By User the Views,Tables,Store Procedures and Privileges to be able to import this information into a Excel spreadsheet.
Hello, I want to see the permissions assigned for all objects (tables, views, stored procedures) in all my databases. Has anyone written a script to do this? Just thought I'd ask before reinventing the wheel. I'm on SQL Server 7.0. Thanks, Dan
I just finished doing a search of the archives and found two references in April 98 to what appears to a similiar proglem to what I have. I found no comments after that.
I have recently converted my 4.2x databases to 6.5. Since then, I have been unable to revoke object permissions completely for my users. My front end gives user permissions on tables and views to the users but I only want them to have group permissions. When I use EM or DBArtisan or ISQL to revoke all the user`s permissions, the response is that they are successful but the permission still display and are shown in sp_helprotect. Is this a known "undocumented feature" or a new twist on an old 6.5 problem?
I would like to be able to get a listing of the object permissions for a particular group in a database. I can't find a procedure for doing this. I know I must be overlooking an obvious solution. Does anyone have any suggestions for doing this? Thanks.
I created two differnt objects in a database. Let say user1 is the database object owner.
Now the probelm starts when I use the query analyzer for just selecting the data using sa account(sa is the admin to all db) and when happens is that I cant't read the data using SQL QUERY ANALYZER but if I go to the TBALES through explorer then I can open the table using the same sa account.
I'm looking into processes to move to using database specific roles and migrating specifically assigned user permissions to these roles. I have made progress on listing permissions in the public role and assigning these same permissions to the new role that I have created for the given database. However, when I inspect permissions on tables and other objects, permissions have also been specifically granted for application users in the db. My ojective is to script out the permissions against the database objects (mainly user tables) and then use the output to assign the same permissions to the appropriate role instead. However, I'm having difficulty finding which system table stores the table and column level permissions.
If I do select * from sysobjects, I can see the user tables. However, I can't find the related tables that store user object permissions. For example, sysprotects doesn't store this info and, if I do an inner join on 'id' between these two tables, I don't see any user tables. Where do I look? Are there any useful 'already done' scripts/procs around for these purposes?
I'm trying to identify the objects in master that the role public has select permissions on, but when I run this query, I get 4 results where the default schema is null and the major_id column does not correspond to any records in the sys.all_objects table. Where else can I look to find what objects these are. DBO is listed as the grantor.
I appreciate your help.
SELECT * FROM SYS.DATABASE_PERMISSIONS P, SYS.DATABASE_PRINCIPALS R WHERE P.GRANTEE_PRINCIPAL_ID=R.PRINCIPAL_ID and permission_name='SELECT' and class_desc='OBJECT_OR_COLUMN' and r.name='public' order by r.name desc
I have recently restored a backup of a SQL Server 2000 Database (from my production server €“ which is a shared hosting service) on my dev machine so I can do some testing. The issue I am having is with the permission of objects. Some of the objects were created with the dbo user and some with another login (myLogin). The ones that were created with dbo work fine on my dev machine. The others do not work unless I prefix them with €œmyLogin€?€¦ I get an €œInvalid object name€? if I don€™t prefix them. This is problematic because there are hundreds of stored procs and tables that I would need to modify in order to use them on my dev machine.
Can anyone tell me how to create a new user with the necessary permissions so I can execute my procs and access tables without having to prefix them?
Hope this makes sense €“ please let me know if it doesn€™t.
Using Management Studio how do you script only user and object permissions? I don't want to script the corresponding "Create" statements for each object, only their permissions.
Using Management Studio how do you script only user and object permissions? I don't want to script the corresponding "Create" statements for each object, only their permissions. This was possible in 2000.

Hi There,This is related to a ms access database but since I use the SqlDataSource control I thought I should post here.I have a project that I was working on with this ms access db and using sql controls, everything was working just finesince one day I started getting "Object reference not set to an instance of an object" messages when I try to designa query or retrieve a schema, nothing works at design time anymore but at runtime everything is perfect, its a lotof work for me now to create columns,schemas and everything manually, I've tried reinstalling visualstudio, ado componentsbut nothing seems to fix it, did this ever happen to any of you guys?any tip is really appreciated thanks a lot
Not sure if this is the right forum to post this question to, so if it's not, please accept my apologies.
I'm working in SQL Server 2005 with a database that was migrated to 2005 from SQL Server 2000. I have to alter a trigger on a table for some functionality changes, and when I modify the trigger and then access it through the application the database is working with, I receive this error:
There was a error in the [stored procedure name] procedure. Error Number: -2147217900 Error Description: [Microsoft][ODBC SQL Server Driver][SQL Server]The definition of object '[trigger name]' has changed since it was compiled.
[stored procedure name] and [trigger name] are where the actual names appear in the message.
I've tried running sp_recompile on the trigger, stored procedure, and table that are associated with this, and nothing works. I have dropped the trigger, which allows the save process to complete (but doesn't perform the required functionality, of course), and then re-created the trigger, but the error message still comes up. The compatibility level for the database is SQL Server 2000 (80) (as it was migrated from SQL Server 2000 as I mentioned above).
Has anyone seen this, and if so, how can I fix it?
Help! I have posted this before and I had hoped that the VS2005 SP1 would help my problem. It didn't. My code is shown below. I have dropped a sqlconnection, sqldataadapter and a strongly-typed dataset from the toolbox onto the component designer for my page and written my code. It compiles without any errors but at runtine I receive the system error "Object reference not set to an instance of an object." The error occurs at the first line where the sqldataadapter is mentioned. I have shufflled the code and the error still occurs at first mention of the dataadapter. I have set parameters to a simple string such as "myemail." It hasn't helped. I have used the "Dim" statement as "Dim DaAuthorLogin as System.Data.SqlClient.SqlDataadapter and Dim DaAuthorLogin as New ......) at the start of the private sub generated by the event requiring the data.

I am trying to develop a custom algorithm. I have implemented and tested training methods, however I fail at prediction phase. When I try to run a prediction query against a model created with my algorithm I get:
Executing the query ... Obtained object of type: Microsoft.AnalysisServices.AdomdClient.AdomdDataReader COM error: COM error: DMPluginWrapper; Object reference not set to an instance of an object.. Execution complete
I know this is not very descriptive, but I have seen that algorith doesn't even executes my Predict(..) function (I can test this by logging to a text file) So the problem is this, when I run prediction query DMPluginWrapper gives exception -I think- even before calling my custom method.
As I said it is not a very descriptive message but I hope I have hit a general issue.

Using SQL Server 2k5 sp1, Is there a way to deny users access to a specific column in a table and deny that same column to all stored procedures and views that use that column? I have a password field in a database in which I do not want anyone to have select permissions on (except one user). I denied access in the table itself, however the views still allow for the user to select that password. I know I can go through and set this on a view by view basis, but I am looking for something a little more global.

For the life of me I cannot figure out why i'm getting the "Object Refence Not Set To an Instance of An Object" error after I try and create a Report Services project in Business Intelligence Studio. I've followed all of the steps in similar posts such as checking the ReportServer/web.config file but everything checks out.
Does anyone have any other ideas as to how I can get rid of this annoying error and start creating some reports?
I've ran into trouble while creating a rather simple transformation script component (one input, one output). The only thing it has to do is test the values coming from it's input rows and set the values of the output rows according to some rules; something like:
Code Block
Public Overrides Sub InputBrowser_ProcessInputRow(ByVal Row As InputBrowserBuffer)
If Row.UserAgent.Contains("MSIE") Then 'test input Row.BrowserName = "Internet Explorer" 'set output End If
End Sub
This raises an "Object reference not set to an instance of an object." exception. Commenting out the input (Row.UserAgent) solves the exception, but I actually do need to test the contents of the input row (and by leaving only the output manipulation, the script won't reach it's end, the components remain yellow). What can I do about this?
