Compacting an Access Database

Does anyone know how to compact an Access Database programmatically from LabVIEW?
Can the Database Connectivity Toolset be used?

I have created a LabVIEW solution for the MS Access DB compressing issues we have all seen.
I am actually using the MS Access Compress and Repair function via
Active X. There are ways to also use the Jet Engine to call the same
function, but I could not get it to work using a required DB Password
to be entered. The code uses the Database Toolkit from NI so I hope all
of you have that. It also uses MS Access 2000 active X component. It
should work for any version of Access, but it needs to be recompiled
for different versions of Access. let me know if it works out for any
of you.
The code allows to use a temp folder to create the compressed DB, or to
put it in a backup folder of your choice. It also handles replacing the
original database with the compressed one. The code finds the database
given the connection reference being passed in. I use the ADO
connection string to find the database location and the File DSN in
order to reconnect to the database. I built it for my specific needs
but I am sure any of you can customize it to your needs as well.
Thanks,

Compact MC Access Database with labview

Hello,
How do I compact an MS Access programatically from labview to reduce its ballooning size? I have the database connectivity toolkit.
Thanks,
Ron

What datatypes are you storing? Using the wrong datatype can cause all kinds of size problems--as in the datafile expanding at a rate several times the size of the data you're putting in it...
Mike...
PS: If you are running Windows you have everything that you need. Access is not actually a database package. It's an application development package for creating programs using Jet. Jet is the DBMS that Access uses, and Jet is installed by default with Windows.

[JDBC][ODBC] How to compact access database from Java ?

Hello,
I'm developping a java applcation wich is connected to an MS Access file database.
For now, I don'y compact it but it would be better.
So How can I compact an access database from Java ?
thanks :)

Hi ypiel,
Try this:
1) Download JETCOMP.exe (freeware from Microsoft);
2) Put the following code in your app (assuming your database file name is: "DB.mdb"):
try {
File current = new File("DB.mdb");
File backup = new File("BACKUP.mdb");
if (current.renameTo(backup)) {
Runtime.getRuntime().exec("jetcomp -src:BACKUP.mdb -dest:DB.mdb");
} catch (Exception e) {
System.out.println(e.getMessage());
Best regards,

How can I compact a MSAccess database with java?

Hi.
I have a question (Please Help!!!):
How can I compact a MSAccess database with java-jdbc? Is it posible?
Thanks

MS Access database has a max length limitation of 2.14GB for Access 2000( 1.07G for Access 97), and won't recycle basically space for update/delete sql so tha it's a good idea to use MS Access database for program, which need update/delete frequent ly data. The programmers of HXTT Access(www.hxtt.net) are writing code for CREATE TABLE/DATABASE sql now. If you need a pure Java solution for PACK TABLE/DATABSE urgently in your project, you should send such a requirement to the Support page of www.hxtt.net so that they can schedule complementing such a fucntion. Otherwise, you should pack your databae manually or visit C++ code for Compact an Access Database Programmatically at
http://www.codeguru.com/Cpp/data/mfc_database/microsoftaccess/article.php/c4327/ , or use Easy Microsoft Access MDB MDE Compactor at http://www.easyhr.com.au/software/easy_mdb_mde_compactor.htm.

How to compact and repair a MS Access database with NI CVI 8.5 (and SQL Toolkit)

Hello
I'm using the SQL Toolkit with CVI 8.5 for accessing MS Access Databases.
Is there a possibility to compact and repair the .mdb file with CVI?
Thanks in advance.

Hello Ulrich,
with compact and repair I mean the MSAccess function "Compact and Repair".
Please follow the link below for more details:
http://office.microsoft.com/en-us/access-help/compact-and-repair-an-access-file-HP005187449.aspx
Normally you can execute this function directly in Access or with the Windows ODBC Data Sources Administrator => "Control Panel" => "Administrative Tools" => "Data Sources (ODBC)"...
I want to execute this function via cvi code and not by hand ;-).
Thank you for your support.

Exporting Access database

Hi,
I am exporting an access database using the msaccess exporter tool provided by the omwb. I am getting an error message "Error # 5 - XMLExporter - Invalid procedure call or argument". Pls help me in rectifying the error and do the export successfully.
Thanks in advance.

Hi Deepak,
What version of the Exporter tool are you using? I would recommend using the latest version, 10.2.0.2.0. The latest version of the Exporter tool is available as part of the Oracle SQL Developer Migration Workbench, which is a new, redeveloped tool that extends the functionality and usability of the original Oracle Migration Workbench. It is available for download from OTN:http://www.oracle.com/technology/tech/migration/workbench/index_sqldev_omwb.html.
The Exporter tool is also available with Oracle Application Express Application Migration Workshop - http://www.oracle.com/technology/products/database/application_express/migrations/mig_index.html, which is a new feature in Oracle Application Express 3.0, to assist in the migration of MS Access forms & reports to Oracle Application Express.
To assist in the resolution of your issues, I would recommend that you carry out the following steps on the MDB file you wish to export:
1. Analyze the objects in your .mdb file using the Documenter facility in Microsoft Access. From the menu bar, select Tools, Analyze, Documenter, and then select the objects (for example, tables or queries) for analysis. Remove or resolve any erroneous objects.
2. Ensure the application contains no missing references. Launch the design IDE (use the Alt+F11 keys), and from the menu bar, select Tools, References. Remove or resolve any missing references.
3. Ensure the application compiles successfully. In the IDE view, select Debug, Compile from the menu bar. Resolve any reported errors.
4. Carry out a compact and repair on the database, using the Tools, Database Utilities, Compact and Repair Database menu option.
5. Ensure that all linked tables are valid links. Using the Tools, Database Utilities, Linked Table Manager menu option, verify that all links are up to date and pointing to an existing .mdb file that is not read-only.
If you still experience issues using the exporter tool, please supply the following information:
* Operating System
* Service Pack version
* MS Access version installed
* Version of MDB file to be exported
* MDAC version installed.
I hope this helps.
Regards,
Hilary

How to Protect your Custom Access Database Product - so that you can sell & distribute it?

I'm looking for an update on this topic as I have been away from Access for a couple of years and have not kept up with the latest.
Hopefully they have made it easier to design, develop, sell and distribute custom database solutions. So here goes...
Question A:
If one develops a custom database product with Access 2013 what is the current best way to...
1 - Prevent it from being (too easily) copied
2 - Prevent it from being (too easily) reverse engineered
3 - Prividing a time limited free demo copy?
4 - Providing a demo copy with limited functionality... like limiting the number of records in an important table, or whatever?
5 - What have I left out of this list that should be considered for protecting ones investment in the development of the product? (other than copyright, of course.)
Question B:
What is the latest on being able to migrate an Access database to the cloud?
1 - Entirely online
2 - Part in the cloud and part on the users machine
3 - And what about all that VBA code - is there no way to make that work in the cloud and/or on a web server... or does it all have to be tossed and all the coding redone?
Question C:
What are other alternatives solutions for selling your custom database application while protecting all your investment in developing it?
1 - Write the front end in C++ (so that it is fully compiled) and the back end in ASP with MS SQL Server? (or alternative server side solutions)
2 - Write the whole thing as a server side solution with browser interface?
3 - Or what?
Thanks for any help.

Hi Fran_3,
>>What is the latest on being able to migrate an Access database to the cloud?
In my option, the Access Web app would be a better choise.

Tony

"Connection is closed" closed error while using MS Access database

We are using MS Access database in our project. Recently the database was upgraded to 2000.
After upgrading the database, I get the folowing error when getAutoCommit() is called on a connection -
java.sql.SQLException: Connection is closed
at sun.jdbc.odbc.JdbcOdbcConnection.validateConnection(Unknown Source)
at sun.jdbc.odbc.JdbcOdbcConnection.getAutoCommit(Unknown Source)
The connection is not closed explicity before getAutoCommit() is called, only the statement is closed.
This error is sporadic and occurs under load scenario only (when a lot of connections are open). Once the error occurs, all the database calls fail then onwards. The error was not occuring before the database was upgraded.
I suspect the jbdc-odbc driver. The driver might not be compatible with Access2000 database. Under load scenario, it might be closing connections automatically.
Has anybody faced similar problem before? Where can I find the compatible jdbc-odbc driver? And how to ensure that it is jdbc-odbc driver problem only?
The database verison - MS Access 2000
Java version - 1.3.1_01

can i just point out that there is no support for transactions in Access so I wonder why you are calling autoCommit methods at all...

Access of ms access database and displaying it on applets

I had made the connection thru JDBC and was able to access data from MS Access database when i had written java application program. But when i created one applet and created instance of that class which was making connection to the database thru JDBC and called one method which was returning one value from the database , i was not able to get on the applet(in the text field) . It gave me some security exception saying acces is not allowed.
Please give me the reason for this and send me reply back on this email id

Welcome to the club. There is an on-going discussion from which I too would like to learn this. Try http://forum.java.sun.com/thread.jsp?forum=31&thread=174953.

Not getting the records from Access database

Hi All,
Iam creating a universe based on Access database. I am able to view the data from all the tables except one table. When i try to view the data there is one error message "Syntax error in from clause, State: 37000". Everything is ok at database side. What does this error means?
Please help me on this.
Thanks.

Hi BOCP,
Thanks for your reply. I have resolved my issue. Actually my issue was, I have a table "Date" in universe which was created in Access database, when i tried to view the Date Table values in Universe i was getting that Syntax error in From clause message. I came to know that Date is a keyword or predefined table in WebI & it wont accept that word as a user defined Table. So i renamed that table in Access and Universe. Now my issue was solved.
Thanks,
Swati.

Refreshing Excel 2010 workbook with connection to Access database on shared network drive

I have an Excel 2010 workbook that has a connection to an Access database that's on a shared drive on the company network. I can refresh the data in the regular Excel application but when it's hosted in the browser I get this error message "The data
connection uses Windows Authentication and user credentials could not be delegated."
Next, I installed PowerPivot for SQL server 2008 and used PowerPivot to connect to the same Access database. I uploaded it to a PowerPivot gallery but when I try to refresh the data but it says "the workbook was created in an older version of Excel
and PowerPivot and cannot be refreshed until the file is upgraded." I tried to go to "Manage data refresh" but I get the "Sorry, something went wrong" page. Do I need to install PowerPivot for SQL server 2012 to do scheduled data refreshes?
What about manual refreshes?

Unable to Publish Access database to SharePoint site in 2013

Hi MK,
According to your description, my understanding is that you got an error when you published Access database to SharePoint 2013.
Please deactivate SharePoint Server Enterprise Site Collection features at site collection level and deactivate SharePoint Server Enterprise Site features at site level, then activate them again, compare the result.
Per the error message, please type a value in the ‘Name’ filed, then publish the table, compare the result.
In addition, here is a similar article, please check whether it is useful for you:

I hope this helps.

DW Procedures to connect to MS ACCESS database located on remote server

I am confused about the procedures within Dreamweaver CS3 to connect to a MS ACCESS database on a remoter server.
I am working through a tutorial book, "Dreamweaver 8 with ASP, Cold Fusion and PHP Training from the Source", but the instructions are unclear concerning the procedures to connect to a MS ACCESS database located on a remote server.
The book indicates that the server administration has to create the DSN for you and screen shots indicate that you will result in a list of DSNs to choose from when creating the connections .asp file.
I went through the procedures to create a connections .asp and resulting in a connection without and tables (of course) because I do not initially have any connection information from my remote site.
I have generated the required two lines of code as follows for my MS ACCESS database connection on my remote server:
'Database connection info and provider
strCon="Provider=Microsoft.Jet.OLEDB.4.0;Data Source="&_
Server.MapPath("database\trans.mdb") & ";" &_
"User ID=xxx;Password=xxxxx"
The question that I have is:
How does this connection coding relate to the "connections/conn_newland.asp" file that was create within the Dreamweaver screens? How do I merge the ASP coding? The file (/connections/conn_newland.asp) generated within Dreamweaver is as follows:
<%
'FileName="Connection_odbc_conn_dsn.htm"
'Type="ADO"
'DesignationType="ADO"
'HTTP="true"
'Catelog=" "
'Schema
Dim MM_conn_newland_STRING
MM_conn_newland_STRINT = "dsn=newland;"
%>
Any advice would be appreciated. I know that this is simple but debugging an error from an ASP coding merge would be a "bear" to debug!

I have not used MS Access myself (fortunately) but I believe it works much like the old, old way of achieving a multi-user database in FileMaker.
That is, it is not a true client-server database but more a peer-to-peer database and that each peer opens the same database file which is available to multiple user via file sharing. Therefore as elikness said it should just be a matter of putting the files on your Lion Server and then sharing that folder/volume using SMB sharing.
However one thing to be aware of, since MS Access is not a true client-server database I would imagine it uses record locking to manage simultaneous direct access to records in the same files. File or Record locking is something that has historically been a bit flakey when using Windows clients with a Mac file server (and probably vice versa).
While I am not proposing it as a solution to consider seriously, it is worth you knowing that FileMaker Pro is a database system that is available for both Mac and Windows and depending on how you configure things can be considered to stretch from a configuration very similar to MS Access at the low end all the way to a high-end MS SQL Server style setup at the top end. See http://www.filemaker.com for details.
There is also a a third-party tool available for migrating databases to or from FileMaker Pro and it can convert MS Access databases to FileMaker Pro see http://www.fmpromigrator.com/
You could use FileMaker Pro just on Windows machines if you wish.
