>I'm new to MySQL and am wanting to be connected to the MySQL server and
query across diffrent db's. To my understanding a different db in MySQL
is the same as a schema in Oracle. Am I correct in this thinking?
What I want is to have one DB called projects which has common tables
such as contact_details, postal_codes, language and so on. Then a
number of other db's for different projects. Then project1 has its own
tables but can also see those in the projects db.
In general, if you can put a table name somewhere in a query, you
can also put databasename.tablename in that place to refer to a
table in a different database. MySQL access permissions still apply
(and checking this might slow things down by a tiny bit, but probably
not by much) so you have to have a login granted access to all of
the tables involved. The MySQL privilege system easily handles
having logins with access to their own database plus (possibly
read-only) access to a common database.
