How do you use version control with Access develop

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!

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/

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.

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 decompose.vbs <path to file to decompose> <folder to store text files>. In case you omit the second parameter, it will create 'Source' folder where the database is located. Please note that destination folder will be wiped if it already exists.

Include data in the exported tables

Replace line 93: oApplication.ExportXML acExportTable, myObj.Name, , sExportpath & "\" & myObj.Name & ".table.txt"

with line oApplication.ExportXML acExportTable, myObj.Name, sExportpath & "\" & myObj.Name & ".table.txt"

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.

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

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.

' Writes database componenets to a series of text files
' @author  Arvin Meyer
' @date    June 02, 1999
Function DocDatabase(oApp)
    Dim dbs 
    Dim cnt 
    Dim doc 
    Dim i
    Dim prefix
    Dim dctDelete
    Dim docName

    Const acQuery = 1

    Set dctDelete = CreateObject("Scripting.Dictionary")

    Set dbs = oApp.CurrentDb() ' use CurrentDb() to refresh Collections
    Set cnt = dbs.Containers("Forms")
    prefix = oApp.CurrentProject.Path & "\"
    For Each doc In cnt.Documents
        oApp.SaveAsText acForm, doc.Name, prefix & doc.Name & ".frm"
        dctDelete.Add "frm_" & doc.Name, acForm
    Next

    Set cnt = dbs.Containers("Reports")
    For Each doc In cnt.Documents
        oApp.SaveAsText acReport, doc.Name, prefix & doc.Name & ".rpt"
        dctDelete.Add "rpt_" & doc.Name, acReport
    Next

    Set cnt = dbs.Containers("Scripts")
    For Each doc In cnt.Documents
        oApp.SaveAsText acMacro, doc.Name, prefix & doc.Name & ".vbs"
        dctDelete.Add "vbs_" & doc.Name, acMacro
    Next

    Set cnt = dbs.Containers("Modules")
    For Each doc In cnt.Documents
        oApp.SaveAsText acModule, doc.Name, prefix & doc.Name & ".bas"
        dctDelete.Add "bas_" & doc.Name, acModule
    Next

    For i = 0 To dbs.QueryDefs.Count - 1
        oApp.SaveAsText acQuery, dbs.QueryDefs(i).Name, prefix & dbs.QueryDefs(i).Name & ".txt"
        dctDelete.Add "qry_" & dbs.QueryDefs(i).Name, acQuery
    Next

    WScript.Echo "deleting " & dctDelete.Count & " objects."
    For Each docName In dctDelete
        WScript.Echo "  " & Mid(docName, 5)
        oApp.DoCmd.DeleteObject dctDelete(docName), Mid(docName, 5)
    Next

    Set doc = Nothing
    Set cnt = Nothing
    Set dbs = Nothing
    Set dctDelete = Nothing

End Function

The answer from Oliver works great. Please find my extended version below that adds support for Access queries.
