Currently, you cannot schedule generation of Batch Script in SQLyog. The only thing that can be scheduled are:
- Database Sync Wizard (Tools->Power Tools->Database Sync Wizard)
- SQLyog Notification Services (Tools->Power Tools->SQLyog Notification Services Wizard)
With that I would like to say that the above feature is planned for SQLyog 4.1.
To import a batch script, use Tools->Execute Batch Script…
