In SQL Server, you can run queries across database tables following the
syntax you mention if you have permissions to access both databases and
they are on the same server. I presume the same is true on other (not all)
database engines. If you have the SQL, then use the executesql feature and
This is logically impossible. The role of a database it to store data and
execute queries about the local data. If you have two, which one should
execute the query? Each one of them can only search local data. databases
do not talk to each other.
The only solution is not to do it in a query

If you want to write simpler sqls, the tables should be within the same
database.
