Hi,
Can I use a Context object to create more than one database?
For example:
new CreateDB("db1","c:\db1").execute(this.Context);
new CreateDB("db2","c:\db2").execute(this.Context);Thanks.
Cheers,
An

Sure; the database you've created most recently will further be available as current "database context"; i.e., after having performed the two create commands, the following queries will yield the same result:
new XQuery("db:open('db2')").execute(this.Context);
new XQuery("/").execute(this.Context);Christian

I've created 2 database with the same context. After making changes to the first database, I exported the whole database, but I could not see the changes. I have no problem with the second database. Is the same context the reason?

Do you have a working example that allows us to reproduce the issue? Christian
