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 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
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.
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.
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.
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.)
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 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
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 an application that uses Acces as a backend and VBA as front end. Application is secured and is supplied on a CD with setup.exe.
Can I use VB 2005 and MS SQL to achieve the same?
Would I be able to package my application with all the neccessery files (assuming that client does not have any e.g. SQL server) so that multiple front ends can access data from common source?
Would I be able to secure such an application using only VS 2005?
What would I need to quickly learn how to achieve the above ( any books you can suggest maybe)?
I have a database that is in mssql and I'm using an odbc link to an access database where I want to add records to the mssql table. When I open the linked table in access it does not allow me to add a record. I have created a user account in mssql that has ownership to the database and I use this user in setting up the odbc link.
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 ?
Hi there,I sincerely hope that someone out there can help. I have twoinstances of the SQL 2000 Desktop Engine running. One is on my localmachine for development and the other is on another machine on ournetwork which is the production environment. I have built an Access2003 front end application which connects to this database. Thisworks fine locally, as you would expect. I successfully installed thedatabase on the production machine and am able to connect to it viaAccess 2003 (using the Data Link Properties window) and from thirdparty database manager software (similar to Enterprise Manager). I amnot able to to connect to the database via my application.I am using the "sa" account with a strong password. This is myconnection string:strConnection = "Provider=sqloledb;DataSource=server02;UserId=sa;Password=strong;Initial Catalog=Test"The error I'm getting is:"Connection cannot be used to perform this operation. It is eitherclosed or invalid in this context."The connection string is the only thing that changes in my code when Iswitch from my local to my production database. Is there some reasonthat I can't use the "sa" account in this fashion that I'm not awareof? I'd rather not use integrated security for simplicity's sake asthis is a small, internal application. Also, I would have thoughtthat if that was the issue, I couldn't use "sa" at all, even locally.I'm going to post to the Access group as well but thought someone heremight have some advice to offer as well.Thanks,Barb
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 recently had to reinstall a new instance of SQLServer 2000, but was unable to use the previous server name. As a result, my Access2000 front end is not happy with it's linked tables. I can't seem to find anyplace within Access to universally change the address of the SQLServer used as the back-end for all linked tables.
When I do try to access the linked tables through Access, I get an error, and the option to change the server location. When I try to type-in the new SQLServer location, there is an attempt to reconnect to SQLServer, but a whole lot of errors are generated, and none of the data is transferred into the Access table.
I really don't want to have to re-do my Access front end, so it seems it would be easiest to somehow reinstall SQLServer to have the same server location it used to. Is there a good way to completely erase all traces of SQLServer so that I can have better luck reinstalling it to the same location it used to be in? Just using the uninstall program from SQLServer doesn't seem to be cutting it.
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
How can I configure a front end Access 2000 Database using Microsoft SQL 2000 as a back end environment? Could anybody help me by telling me what are the steps under SQL? Thanks everyone in advance.
Sorry for the lengthy question, but here goes: I currently have an access database with a FE and BE that resides on each users laptop. Weekly they connect to the network and synch the BE the master on a network drive. There are numerous propblems with this as it has grown quite extensive.
We would like to have this be a server based database with the remote users either having access through the web or something else?
A few of the capabilities of the current database: 1. generate and print reports 2. update project forms. 3. enter time logs 4. enter notes
My question is: What are my options for a remote FE? I am well versed in VB6 and Access. Would be willing to learn other languages (VB.net, my SQL, etc.) Would I be able to have the same functionality or would I have to have separate software for certain functions?
