Filter SQL Server Data By User With An Micmicrosoft Access Front End
Sep 20, 2006
I am in the process of migrating 40 access databases to SQL Server and still use an access front end.All of these databases are Identical in structure and purpose. The goal is to centralize all of the databases backends into one Sql server database, but the data needs to
stay seperated by each location(user). I was able to add a location feild to all of the tables to keep the data seperate. Then I imported three of the locations data for testing. I would like to know how could I filter the data on the access frontend, so that it would ask the user for their location and only allow the user to access, update, and delete that Locations data ?
I've got an access front end containing various forms and sub forms, and we have just transferred the data into SQL, for storage, we can use the majority of the forms but, I now have a problem with updating the related data.
We have had problems updating the data, we need to close the form down in order to get amended data to register, just moving onto the next record give an ODBC error message.
Even using this method some details refuse to update, although the changes are initially visible on the form you cannot get them to transfer to the datafile.
the error message we get is
[microsoft][odbc sql server driver][sql server] the text, ntext, and image datatypes cannot be used in the where,having, or on clause, except with the like or is null predicates (#306)
we've checked the structures of the tables and the code in the form (it works in the old access back end).
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
Does anyone know how to link (not import) an sql server table to an access database using script? I tried a few methods but it doesn't seem to be working. Please help.
Afternoon all,Apologies for cross-posting but as my query covers both Access and SQLServer I thought I'd send it both!I have inherited a project to migrate a fairly complex series ofAccess databases into a single proper SQL database with a web frontend.Its quite a nasty job as people are working on a variety of data setsat several Universities around the world and the data has got verymessy; hence the requirement to put it all on one live web enableddatabase server and provide a web-based front end (particularly assome users insist on using Macs so can't run Access as a front endanyway).If anyone could give me hints on how to perform such a migration or ifanyone knows of any good books or other documents on this I'd begrateful for assistance.Many thanksRich MayMuseum of London
Dear Friends, We have MS Access database with Forms and Reports, which was started 10 years ago by users and now the data is growing very rapidly.
Did anyone tried by having MS Access as front end and SQL Server 2000/2005 as backend with minimum modifications to the forms and reports in MS Access?
Please let me know, your ideas and if there are any links in the web or in Microsoft please provide here.
I have a back-end front-end application in MS Access. Instead of using MS Access queries it gets data via recordsets generated from SQL scripts in VBA routines.
I'm planning to upgrade it to use SQL Server as the back-end. However I need to retain the alternative option of using a file based back-end. (It currently has the capacity to be switched between alternative Access .mdb back-end files.) Is there any information available on how to do this and on how to get Access to synchronize between SQL Server and SQL Server CE back-ends? (Eventually the application will be migrated to VB.NET, but that is a long way down the track.)
Writing to tables created by regular users on MSSQL2005
I have users creating tables through an application, I gave them ddl_admin, datareader, datawriter. They can create tables but cannot insert/update data (to their own tables), I cannot insert data either using Access or any other application to those tables created by them (under dbo schema) Is there something I am missing with permissions? Thank you very much
I just changed my Access 2002 database to a SQL Server ADP project. Ihad a form where the user entered a value into a text box and when acommand button on the form was clicked a Report was opened. The reportsrecord source is a query. The query uses the value from the form textbox to restrict the query.Table name = EggsTableone of the columns in the table is named: EggColorForm name = EggColorFormForm text box name = ColorTextBoxThis sql worked for the query before I converted to SQL:SELECT EggsTable.EggColorFROM EggsTableWHERE (((EggsTable.EggColor)=[Forms]![EggColorForm]![ColorTextBox]));This no longer works. Can I change the syntax somehow to get this towork? I tried dropping the brackets around the word "Forms", I trieddropping all the square brackets, etc., nothing worked.I also tried just opening the report with the report's Server Filterproperty set to:EggColor=N'Forms.EggColorForm.ColorTextBox'I tried using the Report's open event to pass the form value directlyto the report. I tried setting a variable from the text box value onthe form. So far, nothing works. Any ideas?
I have a windows 2008 with SQL Server 2008 R2 VM on Azure. I am trying to connect to the SQL server for the first time using SSMS, but have not been able it. I have a VPN tunnel, so I am connecting using Windows authentication. The error I get back from SSMS is:
Login failed for user 'domainusername'. (Microsoft SQL Server, Error: 18456).In the event viewer I see this error message: Login failed for user 'domainusername'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: <local machine>]
I have done the following:
- created an endpoint for port 1433 - opened port 1433 in the firewall - Ran the MSSQLSERVER service as the build-in users Network Services, Local System, and Local Service, and as a local and domain administrator, with the same exact result each time. - I get the same result trying to connect locally or remotely. - I get the same result trying to connect using sqlcmd.
i am almost finished building the front end for an application to manage restaurants. i am developing the front end with access vba, and intend to use sql server as a back end for the service. i just came across a group of people bashing access developers on a different site. i have several restaurants interested in using the service, and believe that the service should be very successfull (i have a very specific customer base that is currently not being targeted). the access component would not be a multiuser application. before i distribute the app i would appreciate any input. am i getting myself into trouble using access vba? should i run scared and switch to a vb.net web service? thanks in advance for any thoughts.
I've created a small company database where the tables reside in a SQLServer database. I'm using Access 2000 forms for a front end.I've got a System DSN set-up to SQL Server and am using links withinAccess 2000 to get to the SQL Server tables.My forms worked fine until I made a few minor changes to the databaseschema on SQL Server (e.g. added a foreign key, or added a column).After that, all the links break - I click on a table link and get anerror msg like "invalid object name."Deleting the links after a schema change and re-adding the links seemedto fix the problem. The forms I'd already created seemed to work fineafter re-creating the links.But then I got more advanced with my forms. I have it set up so thatfor certain entry fields, the combobox gets populated with values froma table (the description appears in the drop-down and the correspondingprimary key value gets populated in the table). I created a number offorms using this technique, entered data, and everything worked fine.Made a small schema change and it broke everything -- not the actualtable links, but the functionality for the drop-downs. My values nolonger appeared, and this was true for forms that accessed tables whoseschemas did not change.This is driving me nuts. Is there any way to keep my forms frombreaking each time I make a small schema change?Thanks.- Dana
I am using Access 97 as a front end to access SQL 7 server on NT 4.0 server. I've set up security model based on NT authentication only. Users have login right to login to SQL and they have public & dataread & denydatawrite access. They also have SELECT permission on a table object and have no permission to INSERT, DELETE and UPDATE. When I use Access 97 to access a database, users are still capable of inserting and deleteing records in tables.
Maybe because I have worked mainly with VB as a front end to SQL Server so I am biased, but I now need definite reasons (I am on a committee for potential future directions) for using VB as opposed to Access for front ending SQL/Oracle, etc. I would also like to use ADO as oppose to DAO. Right now we are using Access with DAO.
We have just moved a largish Access database (180mb, 78 tables, largest tables have about 250k records) to SQL 2k. The original app had an Access back end (now loaded to SQL), and an Access front end (on each client) which is using some local temporary tables, about 600 queries, and several thousand lines of code using ADO and DAO). The Front end was relinked to SQL back end. When testing everything seemed to run OK, but under load (15-20 users) the new app just crawls. Routines that used to take seconds now take 10s of minutes. ODBC timeouts or blocks are common.
Any idea why should the SQL back end be so much slower than Access. both the Access back end and SQL2k are on the same server (Win 2k Adv. with RAID 5, dual 600mhz Pent III, 512Mb RAM). I realize that Access is not the best front end but that is what we have to work with.
Any help would be appreciated, as I am ready to swith back to Access.
My company uses MS SQL Server for the back end and a Retail specific CRM as the front end. I wish to develop some internal peices of software for our use. I was planning on doing this with access.
my options are:
*Use access as front end and backend *Use access as front end and SQL server as backend (create new DB) *Use other front end and SQL Server as backend.
My question is, what are some good front ends that are availble for reletively small demands? How does Visual Studio come into play?
*Also, I would prefer to be able to create a .exe. I dont think access alows that. I would not want users to be able to go in (or even see) the tables and queries. They should only be able to see the one main menu form at the very least.
When I build an MS Access front-end for an SQL Server backend, how does it take care of data integrity and concurrency , if it is only a front-end ? Is Access smart enough to do the job ?
Hello,I have an sql server 2000 on the network and one installed locally inmy computer. I use access as front-end.I go through odbc to connect to the sql server on the network.I was wondering if it is possible to setup the access file to link toeither server.I need to do this because I would like to use the local server as testenvironment. I know I could achieve that by creating 2 users on my XPclient and having odbc liking depending of the users.Is any other way to do that without login and logoff everytime I wantto use a different database.thanks,Giovanni
This is my first time to deploy an asp.net2 web site. Everything is working fine on my local computer but when i published the web site on a remote computer i get the error "Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed" (only in pages that try to access the database) Help pleaseee
I would like to know if there is a way to find out who changed a users roles/access WITHOUT using the audit function. For example, if a user account was created and given SA access then changed to read only, how can I find out who made that change? I tried searching for an answer, but kept getting no results. I'm thinking this may tie into the sys.sysusers view?
HI, i am working on ASp.net web applicaton , i am using the following connection string in my web.config file. <add name="X_Conn" connectionString="Data Source=XXX;Initial Catalog=XXX;User ID=XX; Password=XXX;" providerName="System.Data.SqlClient"/> How can i get this connectionString attribute value from the front end.
If I'm using an Access front-end, and the data is on SQL Server being accesses via a linked table, and I create a query in Access, Where is all the work done?
I know access has the option of using a pass-through method, but if I do not use it, is Access processing the query locally? I plan on migrating several tables to SQL because the sizes are getting to large for Access and want to know if their will be a performance increase with out re-writing the queries in Access.
I'm using SQL server 7 on Win NT. I have Access 97 as a front end, with linked tables though ODBC to SQL Server. Everytime I open a table in Access, a session appears when I type sp_who2. I close that table in Access, but I when I type sp_who2 the table session is still present. Does anyone know a cause for this?
I am researching why sometimes when we close are queries and tables in Access we have sessions in SQL server that becomes orphans/ghost. I try to kill the session but can't, so therefore I have to recycle the database.
We use SQL Server 2000 on the back-end of our directory web site and ASP on the front end which works fine. However, for my own uses (since I don't create the asp and have to pay a programmer), would it be better to set up an Access 2003 project for my own data entry forms, standard reports and quick searching?
What would be the negatives of this approach. Remember, this is just for me.
I'm using a legacy application built using VB5 and SQL Server 7. After recompiling it, and putting the database in SQL Server 2012. I want to access the current login user using the SQL function SUSER_SNAME().
This is the code.
Set rdoRes = goDatabase.Connection.OpenResultset("select suser_sname()")
But I'm unable to get the current user login in the application. If I write any other SQL statement instead of this, then it runs. But only this statement is not running. Is there any security reasons for this?
4 Layered Web Application for Inserting data into a database using sql server as the back end and a web form as the front end using C# . Can someone provide with code as I am new to this architecture and framework. Better send email. Thanks In Advance, A New Bie
I have a system that has the tables on an SQL Server with the front-end on a Microsoft access database. They are connected via odbc and the tables are linked to the access front-end. The odbc connects to the sql server via a user created for the purpose that only has rights to this database. This user has rights set so that they can access/alter any data in the database.
When my users try to alter data on some of the linked tables they get "The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time." This does not happen to every table only on some of them.
This happens even when there is only one user accessing the system. If I log into the enterprise manager I can alter those tables/ records without any problem (as some articles I’ve read say if the problem is connected to a corrupt record its not possible to then alter that record and sql server should give me an error message instead).
I have tired. - Compact and repairing the access front-end. - Deleting the links in the access front-end then re-linking them. - Copying the objects from the access to a new blank access db. - I have tried altering the account the odbc uses to login to the SA account. - I have asked the server admin to do the 'compact and repair' on the s.q.l server, shrink I believe it is, as some articles suggest this could solve the problem. - The admin has also tried this on the transaction files (so he has told me).
None of this has worked.
I'm stuck. I don't have any training on SQL server (nor will I be able to have any as I gather the training budget may be needed to fill some finance holes). If anyone has any idea of the answer to my problem or could point me in a direction that I could try investigating I would be very grateful. I have asked the admin if it’s anything to do with transactions, he has told me he does not know how to see those but he will try to find out if we can. Am I shooting in the dark or does this sound like a transaction/process locking problem? Is there something I should be looking for?
My company currently has about 20-25 Ms Access Database that they want toreplace the FE with .net and the BE on SQL.This will be done using Visual Studio 2005. Once the FE is converted to .netand the BE is SQL they all will be accessed through our intranet (sharepoint).I work in Ms Access and intermediate at VBA and just learing SQL through theENTERPRISE MANAGER SCREEN.I am just now looking at what Visual Studio 2005 is, but can some one tell mehow this will all connect?What is the typical route for this process?Ms access to SQL - upsizing wizard or SQL importing?????Ms Access FE to .net - summarize how this is done in visual studio (user facerebuilt) then placed on sharepoint?Can anyone sum this up?--Message posted via http://www.sqlmonster.com
I'm not sure if this question should be in this thread but anyway...
I have a form (Mricosoft Access front end) in which the user enter a Pending Date in one of the fields. The date is populated into my backend (SQL Server) withouht problems. Whenever the issue which had the pending date in the field is resolved I'd like to delete this date from this field and also from the back end. At the moment I'm not being able to pass the "value" Null to my back end (probably because it's a datetime type). I've searched the net throughout and I couldn't find a way around it. Only found solution to when the data is not date but numbers/letters, etc... Any ideas on how can I sort this out?
I am unable to update a table (either by opening it and entering datadirectly or through a form). I have set the recordsettype property toupdateable snapshot and have set the permissions to update inside ofthe SQL Server 2000 to checked. Unfortunately, these items have notworked. Any advice is appreciated. Thanks.Dave Christman
