如何在Access开发中使用版本控制？

我参与了更新Access解决方案.它具有大量的VBA,大量查询,少量表格以及一些用于数据输入和报告生成的表单.它是Access的理想候选者.

我想对表设计,VBA,查询和表单进行更改.如何通过版本控制跟踪我的更改？(我们使用Subversion,但这适用于任何风格)我可以将整个mdb粘贴在subversion中,但这将存储二进制文件,我将无法告诉我只更改了一行VBA代码.

我想过将VBA代码复制到单独的文件中并保存它们,但我可以看到它们很快就与数据库中的内容不同步了.

我们在VBScript中编写了自己的脚本,它使用Access中未记录的Application.SaveAsText()来导出所有代码,表单,宏和报表模块.在这里,它应该给你一些指示.(注意:有些消息是德语的,但你可以很容易地改变它.)

编辑:总结以下各种评论: 我们的项目假设一个.adp文件.为了使用.mdb/.accdb工作,您必须将OpenAccessProject()更改为OpenCurrentDatabase().(OpenAccessProject()如果它看到.adp扩展名,则更新使用,否则使用OpenCurrentDatabase().)
