have problems opening two (or more databases) at the same time.
OPEN DATABASE db1
OPEN DATABASE db2
Then db1 is closed again.
In Lianja you can only have one database open at a time. This is by design.
you can however reference tables in multiple databases like this:
use databasename!tablename select * from databasename!tablename
In Lianja you work against a snapshot of the live data as you state, then in final release the “data source” is a dsn that is used to connect to the live data at runtime.
