Creating Access Database Problem
Mar 13, 2007
Hi
I am trying to create an access database (vb 2005). The code sample below works fine if I create the database without specifying a username and password (values left blank). However if these are specified an exception is thrown. Any help/suggestions would be appreciated.
Try
Dim cat As Catalog = New Catalog()
cat.Create("Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=C:Seans VBAppGeneratorSystemAppGen.mdb;" & _
"Jet OLEDB:Engine Type=5;" & _
"User Id=user;" & _
"Password=pass;")
Console.WriteLine("Database Created Successfully")
cat = Nothing
Catch ex As Exception
Console.WriteLine("Failed to create database")
End Try

Hi,
How do I create a user that has full access to a database using only SQL statements?
I've create very basic database called "sampledb".
Then I've done:
CREATE LOGIN sampleuser WITH PASSWORD = '123sampleuser', DEFAULT_DATABASE = sampledb;
USE sampledb;
CREATE sampleuser FOR LOGIN sampleuser WITH DEFAULT_SCHEMA = 'db_owner';
Then I logon to SQL server express 2005 management studio using this user, first of all I do not see the sampledb database listed under "databases" even though it is selected in the "available databases" toolbar (how do I list it there? Because going through "attach..." tells me I do not have the privileges to browse for the database to attach).
I then open up a new query (sampledb is selected), and type (products is one of the table in sampledb):
select * from products;
And I get:
Msg 229, Level 14, State 5, Line 1
The SELECT permission was denied on the object 'Products', database 'sampledb', schema 'dbo'.
Shouldn't the chosen schema (db_owner) give me the right to do this? And how do I fix this from the query window (without going through the GUI, just using SQL statements)? And how do I list sampledb under the databases when I log in as this user?
Thank you!

I have been using the .NET Enterprise Library for DataAccess patterns for some time now. I'm going back to a bunch of old legacy ADO code written in VB6/VB5 and would like to try and create the same "centralized" class that all of my code can instantiate and call to open database objects, call stored procedures, etc.
Does anyone know of any samples of papers which might describe this?
Thanks very much,
...Andrew

We are running SQL Server 2012 on Windows 2008 Server. In one database, we would like to create a view which access objects in another database without giving the user permissions to the underlying base tables in the other database. The ownership chain is broken in this case. Can this be accomplished (considering the ownership chain is broken)? If so, what is the easiest method to accomplish this task? Or
Example 1 (Works):
In DB1:
--UserA selects from Schema1.View1 (which access tables in DB2).
In DB2:
--UserA exists with select permissions on the base tables accessed by Schema1.View1 (in DB1).
Example 2 (trying to accomplish):
In DB1:
--UserA selects from Schema1.View1 (which access tables in DB2).
In DB2:
--UserA exists (or may not exists) with NO permissions on the base tables accessed by Schema1.View1 (in DB1).

I am trying to create a MS Access datasource to use it in a IS dataflow. I've done the following things:
1.I've created an ODBC datasource - System DSN, pointing to the Access database.
2.I've created an ODBC connection manager pointing to the ODBS datasource that I created in the previous step.
3.I've created a DataReader Source that uses as its Connection Manager the connection manager that I created in the previous step.
I get the following error message: "Cannot acquire a managed connection from the run-time connection manager." What can I do to solve this error?

We have been asked to look into using stored procedures with SQL Server 7.0 as a way to speed up a clients site. 99% of all the articles I have read along with all the books all say Stored Procedure should be used whenever possible as opposed to putting the SQL in your ASP script. However one of my colleagues has been speaking to Microsoft and they said that that they were surprised that our client wanted to use Stored Procedures as this was the old method of database access and that now he should really consider using COM objects for data access as itis much faster. Has anyone got any views on this or know of any good aticles regarding this matter ?

I'm trying to create a linked server to an Access database that resides on a separate machine.
On my PC, I can create a link to the Access db, and view, update, add and delete data. If I create the same linked server on our production Server, I can again view, update, add and delete data. All's well so far.
If I now go back to my own PC (used for developing) I cannot access the linked server on the production machine.
The Access database is stored on a separate PC, so the I'm linking to a remote db. As I said this works fine if I'm sat in front of the PC that the linked server is created on - but not if I use a client PC to connect.
I create the linked server using the following command:
exec sp_addlinkedserver
@server = 'AccLinkedServer',
@provider = 'Microsoft.jet.OLEDB.4.0',
@srvproduct = 'OLE DB Provider for Jet',
@datasrc = '\DatabaseServerAccessDatabase.mdb'
If I run the SQL statement:
SELECT * FROM AccLinkedServer...AnyTableYouLike
I get this error:
Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.
[OLE/DB provider returned message: The Microsoft Jet database engine cannot open the file '\DatabaseServerAccessDatabase.mdb'. It is already opened exclusively by another user, or you need permission to view its data.]
OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OLEDB.4.0' IDBInitialize::Initialize returned 0x80004005: ].
I've searched in the MS knowledge base, and this forum and followed all of the advice that was available, but it still won't work.
Anyone got any other advice, before I go totally insane with this.
Cheers.

Hi!
This is quite weird.
When I first wanted to create assably using:CREATE ASSEMBLY hashfrom 'C:hash.dll'WITH PERMISSION_SET = EXTERNAL_ACCESS... Server returned error:CREATE ASSEMBLY failed because it could not open the physical file "C:TESTS_Run_This_In_SQL2.dll": 2(The system cannot find the file specified.).Then I tried to find file with exec Master.dbo.xp_fileexist 'C:hash.dll'File exists - falseFile is directory - falseParent directory exists - trueConclusion: Server knows that I have hard drive but cannot see the file (by the way file IS THERE 10000%,alright)
2nd TRY:Copy file to a Server PC named 'pluto' in a directory... i try to create an assably:CREATE ASSEMBLY hashfrom '\plutoProjektiECDLhash.dll'WITH PERMISSION_SET = EXTERNAL_ACCESS...SAME THING: The system cannot find the file specified.i try to find file.... SAME THING!
3rd TRY:I copy file to another Server PC, this time i try to find file first:exec Master.dbo.xp_fileexist '\Depoprojekti2ECDLSRCBackuphash.dll'IT WORKS!!! file is found!!! now everything should work....right!CREATE ASSEMBLY hashfrom '\Depoprojekti2ECDLSRCBackuphash.dll'WITH PERMISSION_SET = EXTERNAL_ACCESS.....CREATE ASSEMBLY failed because it could not open the physical file "\Depoprojekti2ECDLSRCBackuphash.dll": 5(Access is denied.).
Now this is fun.
The whole point of this is can somebody tell me what permissions I (or Management Studio or whatever) have to have in order to create an assably from dll?

I have a Microsoft Access application which uses linked SQL Server tables. I would like to create an ODBC DSN which would be available to all users so that I don't have to create a DSN on each machine. Can this be done? The Access application resides on a shared drive (Windows). Thanks for your help.

I had created a CLR function in my db and was able to execute it successfully a couple of months ago. But when I tried to execute it today it was throwing errors saying there was something wrong with the permissions on the assembly. So I decided to drop everything and recreate it except I can not longer create the assembly with EXTERNAL ACCESS permissions. Whenever I try to create the assembly I get the followng error:
Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
I also tried to create the assembly with Unsafe permissions and got the same error. Does anyone know why this error would be occurring now? I tried creating the same assembly on a different SQL 2005 server and it creates successfully and can be executed successfully. Any help would be greatly appreciated!!
Thanks!

I have recently upgraded to SQL2014 on Win2012. The Access front end program works fine.
But, previously created Excel reports with built in MS Queries now fail with the above error for users with MS 2013. The queries still work for users still using MS 2007.Â
I also cannot create any new queries and get the same error message. If I log on as myself on the domain to another PC with 2007 installed it works fine, so I don't think it is anything to do with AD groups or permissions.

I need to determine the following about the current authenticated Windows domain user who is trying to access a SQL Server via a trusted connection.
1 Has the current user been granted login access to the trusted SQL Server?
2 Has the current user been granted access to a specific database?
3 Is the current user a member of a specific database role such as (DB_ROLE_ADMINISTRATORS)?
Thanks,
Sean

I am trying to obtain access to SQL Server Native Client OLE DB provider using :
hr = CoCreateInstance(CLSID_SQLNCLI11, NULL, CLSCTX_INPROC_SERVER, IID_IDBInitialize,
(void **) &PIDBInitialize);
and this fails with 80040154 error. I am using sqlserver 2012 and everything worked perfectly fine as long as my application was running on the same machine as sql server was installed but now that the app is deployed in a different environment in which the app runs on a separate server than the server which has the database and sql server I am failing with this error even though the sql server version on the target server is same as mine.

I developed a database with Access 2003 and everything was working good until my tech came in and reformated my hard drive and install a new Ghost image that met our company standards.
Now I cannot go in and make any changes to any of the tables, queries and forms. All of this started when a new Ghost image was installed on my pc.
The message I get when I try to open my database is "You do not have permission to run "tblSwitchboard." I get the same error message when I try to do anything at all on the database.
I am at a loss as to what to do. Please help.

Before page 12, step by step instructions work!
Then there is code for AllProducts.aspx that doesn't work if one inserts the code
into the DataTutorial project started on page 1. Yes I changed the name of the CodeFile!
The code given for AllProducts.aspx.cs doesn't compile.
I was doing better without the tutorial!
I can gleen out some concepts but that is all.
If that is all, why have a tutorial?

Sorry, I'm a newbie out there when it comes to creating database. I currently have an ASP.Net project which requires a database. I spent the past few days thinking about how to create a proper database for the application but to no avail. I think tis thread might be out of point for tis forum, but i am really in need of help.
Here goes the storyline of my database:
The project is an online project management system, meant for students to submit their deliverables (reports, eg. Minutes, agenda, project monitor chart) Lecturers will access the web application to grade the student’s submission. The application must allow administrators to add in new subjects. When a new subject is added, the subject leader will set a dateline for a particular module to be submitted. Eg, minutes dateline. Once the dateline is due, the system will inform the lecturers in charge of who/which group did not submit the module. Lecturers and subject leaders can then generate warning letters to be sent via email to the students involved. Lecturers and subject leaders will be able to make announcements through the system as well.
A student can either submit his/her work as an individual or as a group.
A student will be studying more than 1 subject.
A subject will consist of more than 1 module.
Every module will have a dateline for its submission.
Students can make more than 1 submission for each module.
Students belong to different groups/classes for different subjects.
For different modules, there will be different fields to be inserted into the database.
Example, in the “Minutes module�, the student will have to be able to key in the objectives, the date of the meeting, the venue, its members, absent members, actual minutes, action by and meeting end time.
In the “Project monitor chart module�, the student will have to key in the week/date, the name of the member, task involved, as well as the status.
When a new subject is created, the subject leader will have to specify the percentage of each different module. (Eg, Exams – 40%, Term test 15%, and so on.)
A subject will also be taught by more than 1 lecturer. So subject leader will specify the lecturers teaching that particular subject.
I hope someone out there can help me out on the construction of a database for the above storyline. Thanks a lot.
