CLR Stored Procedure To Access Ole Datasource, How?
Feb 22, 2006
I tried to write a CLR stored procedure using C# in SQL 2005 to access an Access
database.
When I use the OleDbConnection class in System.Data, the procedure throws SecurityException at runtime.
Output as following:
System.Security.SecurityException: Request for the permission of type 'System.Data.OleDb.OleDbPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Hello. I hope I am posting this in the right place. I am a beginning coder and could really use some help. I have a site which is using the club starter kit as a foundation. I now want to be able to create a new page which looks just like the event_list.aspx page but includes a drop down box. The drop down box will be populated with all of the locations. When the drop down item is selected, the event list will be filtered by location. I have been able to do this writing new code but I want to be able to use a stored procedure using the PagedUpcomingEventList procedure as a model. This is what I have accomplished so far:
I have the drop down box which is populated properly from a new Datasource.
I'm having some issues getting OLE DB Data Sources to work w stored procs in SSIS. Here's the situation.
I have an OLE DB Data Source set up to call a stored proc w no parameters. The stored procedure loops through a set of databases and inserts data from each database into a results table. I'm attempting to return the results table to SSIS, but the Available External Columns are not populating. However, previewing the query in SSIS does show results. The insert in to the results table is done by a call to sp_executesql.
I've tried setting the results table up as a temp table, table variable, and static table. I have NOCOUNT set ON and am only returning one recordset. I've seen the other threads in here about similar problems, but none of their solutions seem to work for me.
I have a stored procedure that takes a date range and returns all the sales in that date range. I'm trying to create the report model for ad-hoc reporting. When I go to create the dataset view, it only lets me select tables or views.... how do I get around this?
For some reason, I run a stored procedure in Query Analyzer and it works fine. When I run the very same procedure in MS access by clicking on its link I have to run it twice. The first run gives me the message that the stored procedure ran correctly but returned no records. The second run gives me the correct number of records but I have to run it twice. I am running month-to-month data. The first run is Jan thru March. Jan and Feb have no records so I run three months on the first set. The ensuing runs are individual months from April onward. The output is correct but any ideas on why I have to do it twice in Access? I am a bit new to stored procedures but my supervisor assures me that it should be exactly the same.
I'm trying to re-write my database to de-couple the interface (MS Access) from the SQL Backend. As a result, I'm going to write a number of Stored Procedures to replace the MS Access code. My first attempt worked on a small sample, however, trying to move this on to a real table hasn't worked (I've amended the SP and code to try and get it to work on 2 fields, rather than the full 20 plus).It works in SQL Management console (supply a Client ID, it returns all the client details), but does not return anything (recordset closed) when trying to access via VBA code.The Stored procedure is:-
USE [VMSProd] GO /****** Object: StoredProcedure [Clients].[vms_Get_Specified_Client] Script Date: 22/09/2015 16:29:59 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON
Hi everyone, im having alot of trouble trying to execute a stored proc from sql express. heres my code DbProviderFactory db = DbProviderFactories.GetFactory("System.Data.SqlClient"); using(DbConnection conn = db.CreateConnection()){
ConnectionStringSettings s = ConfigurationManager.ConnectionStrings["constrolservicetest"]; conn.ConnectionString = s.ConnectionString; conn.Open();
DbCommand cmd = conn.CreateCommand(); cmd.CommandText = "StoredProcedure1"; cmd.CommandType = CommandType.StoredProcedure; DbParameter param = db.CreateParameter(); param.ParameterName = "@test"; param.Value = 2; cmd.Parameters.Add(param); cmd.ExecuteNonQuery(); } ****************************procedure code*************************** Create PROCEDURE dbo.StoredProcedure1 ( @test int ) AS Update temp Set test = @test
The code just doesn't update. I know my connection string is correct because i got the datareader to work, but i just cant get the stored proc to call. Any help will be greatly appreciated. Thanks, -D
Hi. I'm trying to write a stored procedure that will access another database on a different server. How can I set this up in a stored procedure? It is a SQL Server 2000 database and it will be using SQL server authentication. Thanks!
When I put a sqldatasource in my page and want to configure it and add a new connection to it I recieve this error : "object reference not set to an instance of an object" . Do you have any idea about solving this problem. please help me Thanks
Hi I've run into a slight problem with my stored procedure.If I fire a query in a stored procedure, how can I access the results of that query in the stored procedure itself ?? ALTER PROCEDURE GetDetailsOfWebsiteUserForMail @request_id intAS declare @k int select person_id from Website_user w, Request r where r.user_id=w.user_id and r.request_id=@request_id set @k =person_id /* What do I do here??, value returned is unique */ if (@k!=0) /* Exists */ begin /* do something */ end else /* entry on person table does not exist */ begin /* do something */ end
I'm new to SQL server, still in the beginning stage of learning SQL Server. I'm here would like know, besides using the Connectivity from the DTS Designer to connect to different databases, is it possible to connect the database, i.e: Access via stored procedure? and how? Pls advise...
I'm have been trying to look for the solution via a lot of SQL Server site, but fail to get what I want.
What I'm trying to do is something like : First connect to the Database and Query the data, after that insert it into another database....
I have a stored procedure written in MS SQL Server2000 which takes argument(OUTPUT) as a cursor, and fills in the cursor with the record from the table.
I have to run this stored procedure from my C application program running in SUN OS2.9 with the help of ODBC calls.
Can anyone guide me through steps as to how to run the store procedure from my C program and receive records with the help of the cursor.
The store procedure is as follows
CREATE PROCEDURE testCursor @xyzCursor cursor varying OUT AS DECLARE temp CURSOR LOCAL FOR SELECT * FROM table OPEN temp SET @xyzCursor=temp RETURN(0) GO
I trying to create a general stored procedure which updates 1 out of 140 columns depending on the column name provided as a parameter. I'm not having much luck, just wondering if anyone else had tried to do this and whether it is actually possible? Any help would be much appreciated
I'm trying to convert an Access database application to an ASP.NET application with SQL Server 2005 as the database backend. However, I'm having trouble converting some of the queries to SQL stored procedures. Here's an example Access query that I'm trying to convert into working SQL:
SELECT DISTINCTROW EXISTS (SELECT AccountCodeID FROM AccountCodes WHERE CodeID = 22 AND AccountCodes.AccountID = Accounts.AccountID) AS FullTimeInfo, EXISTS (SELECT AccountCodeID FROM AccountCodes WHERE CodeID = 24 AND AccountCodes.AccountID = Accounts.AccountID) AS ShortTermInfo, EXISTS (SELECT AccountCodeID FROM AccountCodes WHERE CodeID = 10 AND AccountCodes.AccountID = Accounts.AccountID) AS GeneralInfo, Accounts.* FROM Accounts INNER JOIN AccountCodes ON Accounts.AccountID = AccountCodes.AccountID WHERE (((Accounts.SummitID)=@SummitID) AND ((AccountCodes.CodeID)=10 Or (AccountCodes.CodeID)=22 Or (AccountCodes.CodeID)=24)) ORDER BY Accounts.LastName, Accounts.FirstName
My understanding is that EXISTS can only be used in the WHERE clause in SQL. Any suggestions on how to properly rewrite this?
Hello,I am having a problem when using access xp as a frontend for sql server2000.I have been trying to update a number of stored procedures (Just simpleadding fields etc) which results in access crashing with event ID 1000 and1001.Does anyone have any ideas as to what could be the problem?Thanks in advance..
I'm trying to access a group of rows in a data source in my script component (transformation). Currently im using the connection manager in the script component, acquire the connection, and issue a query command to get the data. This will happen on every rows being pass to the script component from the data source. Is there a better way to access the a group of rows from the data source?
I have two database SOP and CRM. Both supports windows authentication and SOP suports sql authentication too. Now i have to write a SP in SOP database with identity impersonation (with superadmin authentication) which will do some work with this impersonated id on SOP database but needs to fetch some values from CRM with the current user account - not impersonated account.Lets clear... I want to show the orders generated by all users and in the display grid there is a column like "IsMyCustomer?" which will show the order is to a customer which i have access. In CRM (MS) if i select from FilteredCustomer view i will get the customersid of those under me. And if i left outer join with FilteredOrder view in SOP (with Super Admin windows credentials) which returns orders by current user i will get the desired result.Now the problem is i can't sent two connection credentials to a SP. So what i want is to connect SOP with user's windows credentials (not with impersonation) and from the SP we will Select data with Admin's account. But i don't know is there any way to connect to a linked server with a different credentials. Like when i am selecting from CRM server it will use different credentials.Remember i am using SQL server 2000 and everything should be done through a single SP.I know i can do this easily with two different select from Data access layer. But i am looking for some performance effectinve way. My PM wants this idea to be implemented. I have no chice guys....
I have created a .net application using visual studio .net and sql server destop edition on my pc. I have exported the database tables and stored procedures and imported them into a Sql Server database on a web hosting service. The web host does not allow me to access this database directly through visual studio .net.
My connection string to the external database works ok and I can access my stored procedures through my web pages. I know they accept parameters and that I can receive Return Values from them. However, whenever I try to access any of the tables on the external database through a stored procedure, I get a sqlException saying that the table cannot be found (Invalid object name 'UserList').
I have created a text type command which selects data from one of the tables and this runs through without any errors. I have also managed to Insert a row onto one of the external tables also by using a text type command. My only problem seems to be with commands using stored procedures.
Just in case this is the problem - the owner of the table/procedures on my desktop is shown as dbo but on the external database the owner of the tables is shown as [domainname].co.uk_dbuser while the stored procedures owner is still dbo.
Example of stored procedure on external database:
/****** Object: Stored Procedure dbo.AddUser Script Date: 01/03/2005 21:10:06 ******/ CREATE PROCEDURE dbo.AddUser ( @Username Varchar(20), @Password Varchar(20) ) AS ( Select User_ID From UserList Where User_Username = @Username ) GO
Have tried changing dbo.AddUser to [domain].co.uk_dbuser.Adduser but this would not save because there were too many full-stops!
Any help would be greatly appreciated as I am completely stuck.
I am working in an access data project. I have a stored procedure that runs fine when I open and run it directly in sql. When I use the DoCmd.OpenStoredProcedure method in VB code, the stored procedure also runs fine (and successfully adds records as it should) but then I get an error: #7874 "...can't find the object...'[Name of sp'". This halts the vb code and is a problem. Here's example code from a sp that causes this problem:
Insert into Table (Field1, Field2, Field3, Field4) Select Field1, 'Test', Field5, GetDate() from View1
I understand there may be another syntax to run a stored procedure from access visual basic other than DoCmd. I would very much appreciate guidance as to how to do this.
I'm upsizing a database from Access 2003 to a SQL Express backend combined with an Access frontend. Along the way, I'm trying to shift the larger queries into stored procedures, but many of our queries require variables. I'm having a hard time with the VBA to run this stored procedure, and looking for suggestions that make sense to a relative newbie to VBA.
Here's my code, which is being triggered by a button click on a form containing input boxes StartDt and EndDt for the date range:
Code Block
Private Sub btnDateFormQuery_Click() 'On Error GoTo Err_btnDateFormQuery_Click
If CreateDSNConnection("server", "database", "user", "password") Then '// All is okay. Else '// Not okay. End If
Dim rs_sp As Recordset 'Set in Global Module Dim qdf As QueryDef 'Set in Global Module Dim SP_SQL As String 'Set in Global Module Dim Db As Database Set Db = CurrentDb() Set qdf = Db.CreateQueryDef("qry_Donors") 'Set in Global Module qdf.ReturnsRecords = True 'Set in Global Module qdf.ODBCTimeout = 15 'Set in Global Module SP_SQL = "Execute sp_DonorQRY " & "'" & StartDt & "'" & ", " & "'" & EndDt & "'" qdf.SQL = SP_SQL 'Set in Global Module
'Check Dates for errors Call CheckDates 'Procedure to check dates If CheckDatesErr = True Then Exit Sub ' don't continue End If
'Here is where we need to enter the code that will drive the query.
During Debugging, when I reach the line "qdf.SQL = SP_SQL", I receive the following error: Runtime Error '3129'Invalid SQL Statement; expected 'DELETE', 'INSERT', 'PROCEDURE', 'SELECT', or 'UPDATE'.
I've been able to copy out the value of SP_SQL and paste it into a pass-through query, and it runs beautifully. Just not having any luck trying to script it.
Please advise which kind of connection should be establish from excel 95 to MS SQL Server.
From my thought, I understand that the connection depends on Windows version rather than excel version. Thus, I just think that there will not be any issue connecting to SQL Server from Excel 5.0a.
Kindly advise if there is any addtional point to concern/consider further. What could be issue connecting to SQL Server 2005 from Excel 5.0a.
I would like to provide the db_datareader and db_executor role to a particular SQL Server Login in a database But, I would like to avoid any INSERT's, UPDATE's or DELETE's that may happen by calling the stored procedures
I tried assigning the db_denydatawriter role but it doesn't seem to be doing the trick as the INSERT's, UPDATE's and DELETE's were still working
Is there any way to provide the db_datareader and db_executor role but avoid any DML actions.
