i was experimenting with ado and have come across the following problems:
i've two forms one of which is a main form and the other is a form containing the adoquery1 and grid to display the results of a query.
On running a query and displaying the results if, i close the second form containing the grid and adoquery1,while the query is still running i get a error saying that i cannnot perform the operation an a closed dataset and futher if a say ok to the message it givies me a read address exception error.
i have traied to trap the first error about the dataset but the second error about the read address givies me problem.
I am coding under Delphi a software which will be using a SQL Server 2000. I am using ADO components and have the latest MDAC: 2.8 SP1.
The software is using a lot of TADOQuery objects which are connected to the same TADOConnection. The TADOQuery having for options : - cursorlocation : useclient - cursortype : static - locktype : optimistic
On the first use of a TADOQuery in order to execute any type of request, the processing is fast. If I am using this same object for others requests, everything is fine and as fast as the first request. But as soon as I am using another TADOQuery, performances are going down.
In order to give some numbers, some requests can take as much as 17 seconds to be executed. The same request would take at most 100 milliseconds if it were executed with the first TADOQuery.
It is not a problem concerning indexes; if I try to use the request analyzer, all my requests are processed quickly.
I used the SQL Profiler to see the details and saw some interesting things : the first uses of TADOQuery are of type SQL:BatchCompleted but switching to another TADOquery make it use another type : RPC:Completed. Contents of this RPC can be a declaration or an execution of cursor.
More precisely, if I am using only one ADOQuery, I see one line in the Profiler for every block of code opening/reading contents/closing. But using multiples ADOQuery, I see one declaration of cursor for the opening and then every reading produces one cursorfetch. So, this declaration of cursor may take a long of time and every fetch too and if there is many lines to send to the client, the network is used for each line to send.
Better, using an TADOQuery to make a request and then simply initializing another one by changing the SQL property and then executing a second time the first TADOQuery makes this last execution used as a cursor serverside. The problem should then on the side of the client but I can not figure where.
I hope having been as clear as needed ! My wishes is to not have recode the whole database side of our software because it is huge and badly designed so it will be hard to test everything fine. So before recoding I wish to continue the analysis.
So does anyone knows why is happening this serverside thing ? And is there a simple way to make it not happen ?
create a new Connection Manager by right-clicking in the Connection Managers section of the design area of the screen. Select New OLE DB Connection to bring up the Configure OLE DB Connection Manager dialog box. Click New to open the Connection Manager. In the Provider drop-down list, choose the Microsoft Jet 4.0 OLE DB Provider and click OK. Browse to the Access database file and connection set up---all good!!!

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.
We need to insert data/rows from a SQL Server 2014 database into MS Access database. The problem is, there are so many columns (100+) in the table and there are so many insert transactions of this kind (from different tables) that it is not very easy to write the code in VB.NET that lists all column names.
Both the Access and SQL Server tables have the same number of columns and the equivalent data types, so inserting is not really the problem. It's just that is there a way to do an insert statement in T-SQL that does not name all the columns?
I've been developing desktop client-server and web apps and have used Access and SQL Server Standard most of the time. I'm looking into using SQL CE, and had a few questions that I can't seem to get a clear picture on:
- The documentation for CE says that it supports 256 simultaneous connections and offers the Isolation levels, Transactions, Locking, etc with a 4GB DB. But most people say that CE is strictly a single-user DB and should not be used as a DB Server. Could CE be extended for use as a multi-user DB Server by creating a custom server such as a .NET Remoting Server hosted through a Windows Service (or any other custom host) on a machine whereby the CE DB would run in-process with this server on the machine which would then be accessed by multiple users from multiple machines?? Clients PCs -> Server PC hosting Remoting Service -> ADO.NET -> SQL CE
- and further more can we use Enterprise Services (Serviced Components) to connect to SQL CE and further extend this model to offer a pure high-quality DB Server? Clients PCs -> Server PC hosting Remoting Service -> Enterprise Services -> ADO.NET -> SQL CE
Seems quite doable to me, but I may be wrong..please let me know either ways
The SQL Server is installed on SERVER-A. SERVER-A and SERVER-B are Windows 2003 servers on the same Windows 2003 domain. The SQL Server and SQL Server Agent services are running under the domain account SQLSERVICE. SQLSERVICE is a member of the Domain Admins group. The Domain Admins group is part of the local Administrators group on SERVER-B. The SQLSERVICE account has also explicitly been given Full Control to the folder referenced by \SERVER-BSHARE xp_cmdshell use has been enabled on the SQL Server.
If I run the following command in SQL:
exec master.dbo.xp_cmdshell 'whoami'the following is returned: DOMAINSQLSERVICE If I change the command to access the c: drive instead of a network drive, it executes successfully.
Can anyone shed some light on why I still cannot access any of the files in this folder using xp_cmdshell?
We have an application that requires write settings to reportserver virtual directory for the IUSR account when anonymous is turned on during the install. Once the install is complete, we lock down the IUSR account so that it only has browse access to the virtual directory when enabling anonymous access.
We automate the uninstall and install of our daily builds and I'm trying to figure out if I can automated this process somehow either through command line utility or in vbs.

The update statement is not working in my application, no error in C# and no error in ms-access. When I paste the update query into the ms-access query tool and replace the parameter values (@....) with real values, is will update the record.
Re: Possible Vista-only security issue opening a TCP connection to SQL2005
Please help. I have a problem that appears to be rare. I'm testing the culmination of a year's work and the error I'm getting is at the most basic level (the SQL connection) while everything else so far is working as coded.
My client is Windows Vista, apparently no firewall (I say apparently as in recent years MS have put more and more facades over the actuality of the operating systems), my server is Windows 2003 Server b3790 SP2 with SQL 2005 Standard 1399.06, again no firewall.
PortQuery 2.0 reckons that the server is listening on port 1433, too, so it doesn't seem like a firewall issue.
Nothing reported in either Event Viewers.
Here's the stack dump:
Unhandled Exception: System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

And here's the connection string, which is built using the SqlConnectionStringBuilder:
I have tried an old project which used to connect to the same server using a more basic connection string (it was a project which populated my Research db with fake data) and it also fails. When I ran this project successfully I'm pretty sure it was on an XP client.
I have also ran my TestHarness .exe on another client (WinXP) and it appears to pass this point and raises an exception that I believe is caused at a later point - so it looks like a Vista client issue.
Thanks in advance for your help,
Luke
P.S. Some losely related thoughts; the MSDN forum system still logs me out on Vista when I try to submit a thread, please sort this out! You can't expect your customers to run around deleting cookies. Also, when will you finally deprecate the default Named Pipes!? And finally, having that "does not allow remote connections" error spewed out with all connection errors is a really bad design choice, in my opinion.
I am developing an application that uses Access database (mdb file) to store the user data. The user of this application is not interested in the database file (to view in MS Access Environment). Does the user machine requires MS Access installation to run my application or just some couple of dlls (OleDB driver, Access DB Engine,..) should be enough to run my application?

I have set up a link from ACCESS to a SQL 7.0 database using ODBC (File DSN saved on a shared DRIVE). The link works well only from the workstation where the link was created. But How can I create a link so a group of users can view the linked table in ACCESS without type a password? Any suggestion is appreciated.
We migrated a MS Access 2003 mdb into MS Access 2007. The mdb has linked tables to SQL Server via a DSN and utilizes a mdw file. In 2003, the username/password is "passed" to SQL Server, so the UID/PWD that is used for opening the mdb, is used in SQL Server.
Opening the same file in 2007 using the same mdw, gives a secondary login on SQL Server.
Is there a way to have MS Access 2007 pass the UID/PWD to SQL Server on linked tables, the same way that 2003 does?
When i am trying to start our hospital software based on SQL server 2000, it shows Following Error.Search Condition is not valid, (DBNETLIB) Connection Open (connect()).  SQL server does not exist or excess denied. Due to Fetch data.I run our software in Windows 8.1, while it smothly runs in previous version of Windows XP and 7.
Hello allWould it be possible to migrate the MS Access 2000 to MS SQL Server2000?My application is using MS Access 2000 as database and as userinterface such as forms. Now, I want to migrate the backend databasefrom MS Access 2000 to MS SQL Server 2000. However, I want to keep theMS Access 2000 interface. Would it be possible?If I migrate the MS Access to SQL Server, would the queries, back-endVBA, macro, tables and forms be affected? Do I need to change the MSAccess data type to SQL server supported data type?Which tool I can use to do the migration? Upsizing wizard or exportingthe Access database and then importing it to the SQL server?Thanks in advanceCheersBon
I am trying to connect through ODBC connectivity, but it will not allow me to do so. I have investigated this matter. It leads me back to the server, because as I was configuring my client side database. It kept asking for the DSN(datasource name), but I was unable to choose one because there wasn't one to choose. Which is my current dilemma, How can I do this and have it available to choose from the server to satisfy the Access database?
I went to the domain where the software resides but I don't know what steps to take? I also found an interesting piece on microsoft about Kerberos, but I can't follow along according to the instructions it has. I have Access 2003 & SQL SERVER 2005, HELP...!
Basically, this is right off the heels of the install. I setup the server without the connectivity, but it is running the current configuration.
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 receiving the following errors while trying to import data from an access database.

The source database has "invalid" dates such as "6/4/199" and "12/23/1899". I am unable to change the data in the source database and have been instructed to load the values as nulls in the SQL destination tables. I tried to do a conditional split using a "ISDATE()" function but that is not a valid function for conditional splits.
What are my options for validating the incoming dates are correct or nulling the dates out that aren't

I get too many error messages with access 2000. I can hardly wait until they rolll out office xp at work
I'm trying to re-write my database to de-couple the interface (MS Access) from the SQL Backend. Â As a result, I'm going to write a number of Stored Procedures to replace the MS Access code. Â 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
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 have a client who has SSMS installed on her laptop. She is able to connect to the SQL server via SSMS in the office and query data on the server.
She needs to be out of site often and doesn't have internet access. She asks if the data tables can be "backed up" or saved on her laptop, so she can look at them without worrying connecting to the server. I am not sure if this can be achieved, as SSMS is built for accessing a server, not a desktop. Myself never have this need. If I really need it, I would go to Microsoft Access and create an ODBC connection to the datatables. But this client thinks that Microsoft Access is beneath her.Â
I always used MS Access Database In my programs, now I want to use SQL SERVER database and so I started to design one. but it’s a little bit confusing ,I don’t know what can I use in change of these access Data type :

Hello all,We need to access MS SQL 2000 database from RHEL platforms. I'vetested unixODBC and Easysoft ODBC-ODBC Bridge (under trial license).They work together pretty well. Unfortunately Easysoft ODBC-ODBCBridge is not a free solution. Anybody have any experiences with otherODBC solutions that can make MS SQL accessible to unix? I've heard ofiodbc but without any hands-on details.Thanks in advance for sharing your experience.Bing
