MS Access 的数据库迁移
有很多可用于 Ruby、.NET、SQL Server 等的数据库迁移工具。Access
/VBA 有什么好用的吗?我不得不自己推出几次,但我真的很想将这种负担转移到一个编写良好的工具上。
理想的解决方案类似于 FluentMigrator 或 RikMigrations 包含 DAO 代码的类或模块。
There are a lot of database migration tools available for Ruby, .NET, SQL Server, etc.
Is there anything good for Access/VBA? I've had to roll my own a few times, but I'd really like to offload that burden onto a well-written tool.
The ideal solution would be something like FluentMigrator or RikMigrations with classes or modules that contain DAO code.

当只有需要个人添加的新列时,我倾向于在用户界面中执行此操作。我在后端数据库中有一个临时表,它永远不会被任何用户锁定,在创建新列时,我将其第一个添加到该表中,并仔细检查所有属性是否正确。然后,当用户不使用后端数据库时,我复制并粘贴它,然后允许用户重新登录。
这意味着后端数据库在最短的时间内不可用,并且在创建列时我不会着急。
When there are only new columns to add personally I tend to do this in the user interface. I have a temporary table in the backend database which is never locked by any users and when creating a new column I add it 1st to this table and double check all the properties are correct. Then when the users are not using the backend database I copy and paste it, then allow users back in.
This means the backend database is unavailable for the shortest period of time and I am not rushed when creating the columns.
