How do you use version control with Access development?

I'm involved with updating an Access solution. It has a good amount of VBA, a number of queries, a small amount of tables, and a few forms for data entry & report generation. It's an ideal candidate for Access.

I want to make changes to the table design, the VBA, the queries, and the forms. How can I track my changes with version control? (we use Subversion, but this goes for any flavor) I can stick the entire mdb in subversion, but that will be storing a binary file, and I won't be able to tell that I just changed one line of VBA code.

I thought about copying the VBA code to separate files, and saving those, but I could see those quickly getting out of sync with what's in the database.

We wrote our own script in VBScript, that uses the undocumented Application.SaveAsText() in Access to export all code, form, macro and report modules. Here it is, it should give you some pointers. (Beware: some of the messages are in german, but you can easily change that.)

EDIT: To summarize various comments below: Our Project assumes an .adp-file. In order to get this work with .mdb/.accdb, you have to change OpenAccessProject() to OpenCurrentDatabase(). (Updated to use OpenAccessProject() if it sees a .adp extension, else use OpenCurrentDatabase().)

decompose.vbs:

' Usage:
'  CScript decompose.vbs <input file> <path>

' Converts all modules, classes, forms and macros from an Access Project file (.adp) <input file> to
' text and saves the results in separate files to <path>.  Requires Microsoft Access.

If you need a clickable Command, instead of using the command line, create a file named "decompose.cmd" with

cscript decompose.vbs youraccessapplication.adp

By default, all exported files go into a "Scripts" subfolder of your Access-application. The .adp/mdb file is also copied to this location (with a "stub" suffix) and stripped of all the exported modules, making it really small.

You MUST checkin this stub with the source-files, because most access settings and custom menu-bars cannot be exported any other way. Just be sure to commit changes to this file only, if you really changed some setting or menu.

Note: If you have any Autoexec-Makros defined in your Application, you may have to hold the Shift-key when you invoke the decompose to prevent it from executing and interfering with the export!

Of course, there is also the reverse script, to build the Application from the "Source"-Directory:

compose.vbs:

' Usage:
'  WScript compose.vbs <file> <path>

' Converts all modules, classes, forms and macros in a directory created by "decompose.vbs"
' and composes then into an Access Project file (.adp). This overwrites any existing Modules with the
' same names without warning!!!
' Requires Microsoft Access.

Again, this goes with a companion "compose.cmd" containing:

cscript compose.vbs youraccessapplication.adp

It asks you to confirm overwriting your current application and first creates a backup, if you do. It then collects all source-files in the Source-Directory and re-inserts them into the stub.

Have Fun!

It appears to be something quite available in Access:

This link from msdn explains how to install a source control add-in for Microsoft Access. This shipped as a free download as a part of the Access Developer Extensions for Access 2007 and as a separate free add-in for Access 2003.

I am glad you asked this question and I took the time to look it up, as I would like this ability too. The link above has more information on this and links to the add-ins.

Update:
I installed the add-in for Access 2003. It will only work with VSS, but it does allow me to put Access objects (forms, queries, tables, modules, ect) into the repository. When you go edit any item in the repo you are asked to check it out, but you don't have to. Next I am going to check how it handles being opened and changed on a systems without the add-in. I am not a fan of VSS, but I really do like the thought of storing access objects in a repo.

Update2:
Machines without the add-in are unable to make any changes to the database structure (add table fields, query parameters, etc.). At first I thought this might be a problem if someone needed to, as there was no apparent way to remove the Access database from source control if Access didn't have the add-in loaded.

Id discovered that running "compact and repair" database prompts you if you want to remove the database from source control. I opted yes and was able to edit the database without the add-in. The article in the link above also give instructions in setting up Access 2003 and 2007 to use Team System. If you can find a MSSCCI provider for SVN, there is a good chance you can get that to work.

The compose/decompose solution posted by Oliver is great, but it has some problems:

• The files are encoded as UCS-2 (UTF-16) which can cause version control systems/tools to consider the files to be binary.
• The files contain a lot of cruft that changes often - checksums, printer information and more. This is a serious problem if you want clean diffs or need to cooperate on the project.

I was planning to fix this myself, but discovered there is already a good solution available: timabell/msaccess-vcs-integration on GitHub. I have tested msaccess-vcs-integration and it does work great.

Updated 3rd of March 2015: The project was originally maintained/owned by bkidwell on Github, but it was transferred to timabell - link above to project is updated accordingly. There are some forks from the original project by bkidwell, for example by ArminBra and by matonb, which AFAICT shouldn't be used.

The downside to using msaccess-vcs-integration compared to Olivers's decompose solution:

• It's significantly slower. I'm sure that the speed issue can be fixed, but I don't need to export my project to text that often ...
• It doesn't create a stub Access project with the exported stuff removed. This can also be fixed (by adopting code from the decompose script), but again - not that important.

Anyway, my clear recommendation is msaccess-vcs-integration. It solved all the problems I had with using Git on the exported files.

Olivers answer rocks, but the CurrentProject reference was not working for me. I ended up ripping the guts out of the middle of his export and replacing it with this, based on a similar solution by Arvin Meyer. Has the advantage of exporting Queries if you are using an mdb instead of an adp.

We developped our own internal tool, where:

1. Modules: are exported as txt files and then compared with "file compare tool" (freeware)
2. Forms: are exported through the undocument application.saveAsText command. It is then possible to see the differences between 2 different versions ("file compare tool" once again).
3. Macros: we do not have any macro to compare, as we only have the "autoexec" macro with one line launching the main VBA procedure
4. Queries: are just text strings stored in a table: see infra
5. tables: we wrote our own table comparer, listing differences in records AND table structure.

The whole system is smart enough to allow us to produce "runtime" versions of our Access application, automatically generated from txt files (modules, and forms being recreated with the undocument application.loadFromText command) and mdb files (tables).

It might sound strange but it works.

Based on the ideas of this post and similar entries in some blogs I have wrote an application that works with mdb and adp file formats. It import/export all database objects (including tables, references, relations and database properties) to plain text files. With those files you can work with a any source version control. Next version will allow import back the plain text files to the database. There will be also a command line tool

You can download the application or the source code from: http://accesssvn.codeplex.com/

Resurrecting an old thread but this is a good one. I've implemented the two scripts (compose.vbs / decompose.vbs) for my own project and ran into a problem with old .mdb files:

It stalls when it gets to a form that includes the code:

NoSaveCTIWhenDisabled =1

Access says it has a problem and that's the end of the story. I ran some tests and played around trying to get around this issue and found this thread with a work around at the end:

Can't create database

Basically (in case the thread goes dead), you take the .mdb and do a "Save as" to the new .accdb format. Then the source safe or compose/decompose stuff will work. I also had to play around for 10 minutes to get the right command line syntax for the (de)compose scripts to work right so here's that info as well:

To compose (say your stuff is located in C:\SControl (create a sub folder named Source to store the extracted files):

'(to extract for importing to source control)
cscript compose.vbs database.accdb     

'(to rebuild from extracted files saved from an earlier date)
cscript decompose.vbs database.accdb C:\SControl\Source\

That's it!

The versions of Access where I've experienced the problem above include Access 2000-2003 ".mdb" databases and fixed the problem by saving them into the 2007-2010 ".accdb" formats prior to running the compose/decompose scripts. After the conversion the scripts work just fine!

Text-file only solution (queries, tables and relationships included)

I have altered the Oliver's pair of scripts so that they export/import relationships, tables and queries in addition to modules, classes, forms and macros. Everything is saved into plaintext files, so there is no database file created to be stored with the text files in version control.

Export into text files (decompose.vbs)

' Usage:
'  cscript decompose.vbs <input file> <path>

' Converts all modules, classes, forms and macros from an Access Project file (.adp) <input file> to
' text and saves the results in separate files to <path>.  Requires Microsoft Access.

You can execute this script by calling cscript compose.vbs <path to file which should be created> <folder with text files>. In case you omit the second parameter, it will look into 'Source' folder where the database should be created.

Import data from text file

Replace line 14: const acStructureOnly = 0 with const acStructureOnly = 1. This will work only if you have included the data in exported table.

Things that are not covered

1. I have tested this only with .accdb files, so with anything else there might be some bugs.
2. Setting are not exported, I would recommend creating the Macro that will apply the setting at start of the database.
3. Some unknown queries sometimes get exported that are preceded with '~'. I don't know if they are necessary.
4. MSAccess object names can contain characters that are invalid for filenames - the script will fail when trying to write them. You may normalize all filenames, but then you cannot import them back.

One of my other resources while working on this script was this answer, which helped me to figure out how to export relationships.

There's a gotcha - VSS 6.0 can only accept MDB's using the add-in under a certain number of objects, which includes all local tables, queries, modules, and forms. Don't know the exact object limit.

To build our 10 year old prod floor app, which is huge, we are forced to combine 3 or 4 separate MDBs out of SS into one MDB , which complicates automated builds to the point we don't waste time doing it.

I think I'll try the script above to spew this MDb into SVN and simplify builds for everyone.

For those using Access 2010, SaveAsText is not a visible method in Intellisense but it appears to be a valid method, as Arvin Meyer's script mentioned earlier worked fine for me.

Interestingly, SaveAsAXL is new to 2010 and has the same signature as SaveAsText, though it appears it will only work with web databases, which require SharePoint Server 2010.

We had the same issue a while ago.

Our first try was a third-party tool which offers a proxy of the SourceSafe API for Subversion to be used with MS Access and VB 6. The Tool can be found here.

As we were not that satisfied with that tool we switched over to Visual SourceSafe and the VSS Acces Plugin.

I'm using Oasis-Svn http://dev2dev.de/

I just can tell it has saved me at least once. My mdb was growing beyond 2 GB and that broke it. I could go back to an old version and import the Forms and just lost a day or so of work.

I found this tool on SourceForge: http://sourceforge.net/projects/avc/

I haven't used it, but it may be a start for you. There may be some other 3rd party tools that integrate with VSS or SVN that do what you need.

Personally I just keep a plain text file handy to keep a change log. When I commit the binary MDB, I use the entries in the change log as my commit comment.

For completeness...

There's always "Visual Studio [YEAR] Tools for the Microsoft Office System" (http://msdn.microsoft.com/en-us/vs2005/aa718673.aspx) but that seems to require VSS. To me VSS (auto corrupting) is worse than my 347 save points on my uber backuped network share.

i'm using the Access 2003 Add-in: Source Code Control. It works fine. One Problem are invalid characters like a ":".

I'm checkin in and out. Internly the Add-In do the same as the code up there, but with more tool support. I can see if an object is checked out and refresh the objects.

You can also connect your MS Access to the Team Foundation Server. There is also a free Express variant for up to 5 developers. Works really well!

I tried to help contribute to his answer by adding an export option for Queries within the access database. (With ample help from other SO answers)

Dim def
Set stream = fso.CreateTextFile(sExportpath & "\" & myName & ".queries.txt")
  For Each def In oApplication.CurrentDb.QueryDefs

	WScript.Echo "  Exporting Queries to Text..."
    stream.WriteLine("Name: " & def.Name)
    stream.WriteLine(def.SQL)
	stream.writeline "--------------------------"
	stream.writeline " "

  Next
stream.Close

Haven't be able to work that back into the 'compose' feature, but that's not what I need it to do right now.

Note: I also added ".txt" to each of the exported file names in decompose.vbs so that the source control would immediately show me the file diffs.

Hope that helps!

This entry describes a totally different approach from the other entries, and may not be what you're looking for. So I won't be offended if you ignore this. But at least it is food for thought.

In some professional commercial software development environments, configuration management (CM) of software deliverables is not normally done within the software application itself or software project itself. CM is imposed upon the final deliverable products, by saving the software in a special CM folder, where both the file and its folder are marked with version identification. For example, Clearcase allows the data manager to "check in" a software file, assign it a "branch", assign it a "bubble", and apply "labels". When you want to see and download a file, you have to configure your "config spec" to point to the version you want, then cd into the folder and there it is.

Just an idea.

For anyone stuck with Access 97, I was not able to get the other answers to work. Using a combination of Oliver's and DaveParillo's excellent answers and making some modifications, I was able to get the scripts working with our Access 97 databases. It's also a bit more user-friendly since it asks which folder to place the files.

I am using OASIS-SVN from https://dev2dev.de/ This is not for free but for a small price.

It exports code, qrys, frms etc. to a folder. From there I am using Git.
