MYSQL as front-end to MS Access via LabView

Hello members,
There is a part in my project where a program writes to a MS Access database (DB). I want to be able to take this Access DB and use it to update a MySQL DB using LabView. I have already created the DB in MySQL with exactly the same structure as the DB in MS Access. Basically, what I am trying to do is that every time the MS Access DB is updated I want to be able to post-run a VI to update the MySQL DB. So MySQL DB is my front-end for MS Access. I have the data connectivity package and I have tried couple things but in vain. I can insert data into MySQLDB but I have not been able to update a specific existing column in a specific existing table. I have searched online too for possible ways to do it and most discussions/ solutions are for MS Access to be the front-end for MySQL (I need the opposite to be working). Some other discussions were for migrating MS Access to MySQL, but it is not what we are trying to do. The MS Access DB will always be there. I do have all permissions to read/write to both DB.
I will appreciate any suggestions or input you may be able to provide or if there is a better/ efficient way to do it.

Based on your description I don't see how either database is a "front-end" to either one. It sounds to me like you are updating the two databases in parallel. For it to be a "front-end" MySQL would need to update the Access database directly, not LabVIEW. So LabVIEW would know nothing about the Access database. This means all the work would be inside of MySQL (such as with triggers on table updates and insertions, which I'm not sure if MySQL even has).
I don't understand your statement about being unable to update a specific existing column in a specific existing table. What exactly are you trying? What VIs are you using? What are your inputs? Can you post your code and a quick overview of your schema?

  • Pkgbuild: rekall - kde db front-end (like ms access)

    I finally found some time to finish PKGBUILD for non-commercial version of rekall - a database front-end  similar to microsoft access. I built rekall with support for 3 types of databases:
    - postgresql
    - mysql
    - xbase/xbsql - dbf (dBase IV and Clipper) files
    Rekall also supports python scripting and it should work but I'm not a python programmer so I didn't try it :-). I built rekall with kde gui. It's theoretically possible to build it only with qt and without kdelibs but it is not advised (broken, too old, etc.)
    It is also possible to build OS odbc proxy support (for accessing other databases from windows hosts for conversion, etc.) for this version of rekall but I didn't have time to test it and to build more packages. Check this page if you want to try it too http://www.rekallrevealed.org/toplevel/ … vers.shtml. Commercial version features are presented here http://www.thekompany.com/products/rekall/
    It would really be nice to have a precompiled package in some repository because it takes aaaaaages to compile it. Anybody?

    If you find something that can be improved please post it here.

    being the redevelopment of the order processing modules (as described earlier).Where are these order processing modules? MS Access just stores the data. Where is the business logic to actually process the data, interface with other business systems, etc? If all that is in Access or MS-related components too, I would stand by my earlier recommendation. You dont just "inject" HTML DB as just a front-end development platform/language, like you do for example PHP, Perl or whatever.
    Given that you would like to migrate the entire system over to Oracle eventually, I think starting with the front-end is a little backwards. I would suggest using data migration tools like the Oracle Migration Workbench and stuff to migrate your data over to Oracle first and then build your HTML DB application on top of it.
    Thanks.

  • How to implement Oracle user/role security with Access front end?

    Hi,
    We have successfully migrated our Access database tables to Oracle 10g using SQL developer. We've recreated all the users and roles(i.e., access groups) in Oracle and granted rights to tables.
    In the Access front end database, in the Database window we have saved linked Oracle tables which replaced the Access tables. The forms, reports, queries run fine with the linked Oracle tables. All the linked table use one ODBC DSN to the Oracle database with the same Oracle user id.
    We need to be able to authenticate users into the Oracle database and RE-link the tables based on their own unique user id. By during so we can allow users to use the Oracle standard user id/role and system privileges to control select, update, ect. rights to the database.
    I've been able to use the VB code within Access to logon into the database with a unique id, but I have not been able to find out how to RE-link the tables to the unique user id using VB. There should be some way to relink tables dynamically, based on users login into the Access front end.
    I don't know a great deal about Access projects, but I do know with SQL server allows login into your Access project and link tables dynamically.
    Can someone give me some assistance or point me in the right direction?
    Thanks in advance,
    Larry

    We had one of our programmers here come up with a VB code solution for re-linking table within Access. However the relinking takes 3-4 minutes for 100+ tables.
    In an effort to help you understand the situation better, I will attempt to elaborate on the problem:
    We have an Access 2003 application which currently has a front end using Access(forms, reports, queries, & VB code) and a MS Access 2003 backend.
    We have migrated the backend tables to Oracle. However, we still have a need to maintain the front end in Access, since we have over 60 forms, 40 reports, 200+ queries in Access. Its easy to understand, we have a significant investment in the front end(Obviously, the plan is to migrate the front end also at some future date).
    In order to utilized the existing front end, we have to validate and modify the current front end connections to the new Oracle backend. One of the features of Access is that you can "link" tables and save the link for runtime. Each Access table can have its own link which is a separate ODBC/JET connection. As such, each separate link has its own userid/database information.
    The other issue with using the Access front-end is that Access utilizes a workgroup file to implement user and group security. The workgroup file contains all the users and which groups the users belong to in Access. Then within Access, you allow users access to object(tables, queries, ect) by their userid and or group. When users open an Access database with Access security enabled, they are required to log into Access. The login is authenticated by the workgroup file. Once, logged into Access, users have rights to Access objects based on their rights granted to their userid and groups they belong. The problem here is that when you remove the linked Access tables and replace them with linked Oracle tables, Access has knowledge about Oracle table rights granted to users; nor would you expect it to.
    The dilema is the disconnect between Access and the fact Oracle utilizes a similar but much more sophisticated security model. It creates users and roles(which are similar to Access groups), and again this is independent of Access security.
    Our solution was to still use the Access workgroup file security along with the Oracle security model. By using the Access userid and then creating a similar Oracle userid with similar table rights granted in Access, you could apply security within Access and also with the Oracle database.
    For example, a user BOB logs into Access via the workgroup file, using VB code, Access then establishes a Oracle connection logining into Oracle using the same unique userid BOB into Oracle.
    After connecting and validating user BOB into Oracle, then the Access tables are relinked to Oracle using the user BOB userid and table rights.
    This Oracle userid has been granted table rights specific for this userid.This allows the user BOB to use the Access application and still be authenticated into the Oracle database.
    The problem with this solution is that the relinking of the saved Access tables takes 3-7 minutes for about 100+ tables. This is not acceptable for users each time they log into the application.
    Our current alternative is to use one Oracle userid to login each user, and use Access form restrictions/security to allow/prevent users from updating/viewing data. Obviously, this is not the optimal solution in respect to security, but it at least allows us to control access to the data(via the forms) by using one logon required for each user, and quick startup time for the application.
    I understand SQL server does a better job in integration, but we use Oracle which is what I am trying to work with.

  • Can we run in Background job which can pick a file from front end ?

    Hi All,
    I would like to run a report in Background job , for this i need to pick a file from front end services(Local drive or share folder)
    Is there any alternate FM=>GUI_UPLOAD  to upload data from front end services or any other solution for this?
    I am getting error=> "No batch" and " Cannot perform frontend function in batch input mode"
    Could you please help on this ?
    Thanks for your help in advance.
    Regards,
    Prasad.

    Hello Prasad,
    IF you keep your file on a shared folder on your front end, you can access it via OPEN DATASET if your application server has access to that path.
    You can test it out by asking Basis to try and access your front end file from the app server itself.

  • Uploaded file (via front-end) created as a Media Download item (Literature Item)?

    Is it possible to have an uploaded file (via a form or webapp edit form on the site front-end) to be stored/created as a Media Download item (Literature Item)? Or alternatively, is it possible to secure a file that has been uploaded on the front-end (by 'secure' I mean cannot be access outside of a secure zone)?
    My aim is to have customers upload files into their secure zone and maintain that security on the uploaded file so other cannot access them. I can't see that this will be possible but hopefully someone might have some creative ideas to get around it.

    Hi Adam,
    This can be implemented via web apps, please go through the web app tutorials here to know more about them - User manual
    You can set up a secure web app to take the submissions from the users and include file upload in that submission. Those submissions are visible to only the user who submits it, unless, you enable the option where every one can see/edit it.
    Note: Via the web apps, the files that are uploaded, they go into a folder with a random name which is directly accessible on the internet, even though, on the site, through the web app items, only the logged in users can see it. By this I mean that anyone who has the direct link to the file will be able to access it and it can also be indexed by search engines. So, when it comes to using the work around of web apps to implement this function on your site, make sure to take measure to block Google bots from indexing the files.

  • SQL Server 2005 replaced with SQL Server 2014 trying to connect front end Access as guest (read only ODBC)

    We have replaced a SQL Server 2005 with a SQL Server 2014 (new physical server.)  Have the new server set up to use SQL Server login OR Windows user login. Had old server connecting (for a particular DB) to front end Access (2010 or 2013) as guest for
    anyone logged into the Windows NT Network with a read only ODBC connection. Have the DB in the new server set to include guest as db_datareader (with only SELECT permission for the securables of each table and view being linked) but when any Windows user not
    specifically listed as a SQL DB user tries to use the front end they get an error of:
    Microsoft SQL Server Login
    Connection failed:
    SQL State: '28000'
    SQL Server Error: 18456
    [Microsoft][OCBC SQL Server Driver][SQL Server] Login failed for user {domain\user}.
    After closing that pop-up window a server login window appears. Of course, since the guest user is not specifically listed as a user in the DB that fails also. It seems like there should be a very simple solution to this, but I can't seem to find it. I want
    to allow anyone logged in on the Windows system (locally) to be able to open the MS Access file (on their work station machine) and run their own (read only; select) queries on the SQL Server database. Any suggestions?
    Thanks a billion in advance ----

    Thanks for the response Olaf. I have now spent weeks researching this. I realize that using the guest account in most situations is not advised. As mentioned, I have restricted the guest account to allow the db_datareader role only, and have explicitly denied
    all other roles, as well as allowing select only, and still have no access for the guest account.
    The suggested fix in the second link you provided, of using Windows groups is not plausible for my situation either. We are a scientific field research institution, with a few long term users and lots of users that may have Windows accounts for a few months,
    and then they are gone. It would be a nightmare for the network tech to try to keep a group account up to date, and we need to give access (read only, of course) to anyone logged into the system. Realize that the ONLY access of any kind to this database is
    thru MS Access ACCDB, using a (by default) read only OCDB connection.
    This type of access is used particularly because researchers need to be able to set up their own queries, and the MS Access query interface is particularly convenient for people who are not themselves SQL experts, yet are trying to get some very advanced
    levels of output. Putting the database online is not practical because then we are back to the need for a comprehensive query interface, and just picking up general subsets of the data online (from a basic web page search feature) would be out of the question,
    since the result set would involve hundreds of thousands if not millions of records.
    So - that said - what exactly would you suggest, assuming we don't have the funds to buy a whole new system, and have spent plenty of money with Microsoft's Enterprise level MS Office so that all work stations have MS Access, and Microsoft's SQL Server,
    as well as running our network on Microsoft's network software.

  • Can't printing in front-end when implement LOCL access method 'G'

    We are implementing ECC5.0 and print Purchase Order in normal status.But in recent,user print PO by long printer name with some trouble.So we check the notes,and it recommand us to implement access method 'G'.It seems every thing is OK on front-end printing.Still not work for printing PO on front-end output immediate.If we choose short printer name and access method 'F',it work fine.But SAP will no longer develop method 'F'.Please advise it.

    SAP PO is using background printing. SAP frontend print doesn't support background printing.
    As per SAP Frontend document, You cannot perform front-end printing in the background, as there is not connection to the front end.
    For this, you need to configure network printer.

    Did any one face this error? what could be the resolution?
    We are already on SAP GUI 710 patch level 11

    Appreciate your answers
    Thanks,

    Usually this means, that some necessary controls are not properly registered in the registry and hence can't be found. You may solve that by removing the SAPGUI from the PC completely, booting the machine and reinstall the GUI.

  • How can I use an Access front end and Access button to control a LabView Shared variable boolean?

    My company has invested a lot of money on the office network to write many many access databases and front ends. I'm looking for a way to tie a button on an access front end to toggle a LabView boolean shared variable to notify me when they changed something on their side of the network. I'm not seeing anything that helps on a web or forum search. They don't like the idea of a separate labview control that they have to push a button on to let me know.
    Thanks
    Solved!

    Hi Patrick,
    While this is not the intended purpose of Network-Published Shared Variables, you might be able to accomplish this by writing separate accessor VIs for reading from and writing to the variable, making sure to wire the inputs and outputs. Then, you could build a DLL, making sure that you include the accessor VIs as Exported VIs and include the DLL Library in the Always Included section of the DLL Build Specifications. During this process, you will define the function prototype, which will provide the function call, required parameters, and return values. Once the DLL is created, you can then call it and its functions from another programming language (C, C++, C#, VB, etc.). This may or may not work, but it is the only way that I can think of at this point. I have included some references that may help you in this process.

  • Ms-access XP front-end and oracle ODBC driver

    Hi all,
    I need to set up 5 workstations with ms-access front end accessing an oracle database through Oracle ODBC 9.2.0.5.0 driver and linked tables.
    My main concern is to learn about any issues that may limit what can and can�t be done through access as opposed to an oracle client. I found out that the maximum size of an access XP database is 2GB, but I have not found accurate information as to the maximum number of records ms-access can handle per table. This would be of critical importance to me because the tables I'm working with may eventually hold up to hundreds of thousands of records.
    Concurrency control is also an important topic since 2 or more of the clients may at some point read or write information on the same tables.
    Answers to these questions and any other issues of special importance would be greatly appreciated.
    Thanks a lot,
    JP.

    Just seen this message you had posted to OTN. I am currently looking for some sample codes developing applications using MS Access as front end connected to Oracle database. I appreciate if you can provide me some sample codes that has a master-detail-relationship type of access form that performs an inserts into the master and detail table. Thanks a lot.

  • Removing admin password form Access 2003 database front end and back end

    We have a legacy database that has been passed down from the original creator, who is no longer with the organization. It was created in Access 2003. It has a front end and a back end. The original admin password can not be located and we are in the process
    of upgrading this application to 2010.  Is there a way to remove that password so we can make changes to the original files?

    Hi,
    What password are you talking about, the one created with the workgroup manager? That will be difficult since 2010 doesn't have the workgroup manager anymore. You can still use the database in the 2010 environment but you can't make any changes to the original
    database without the password.
