how can I solve following problem:
On a standalone Linux-PC I wish to locate several
databases in the directory ../pgsql/data, viz:
1. readers_DATABASE with about 20 tables the readers_TABLE has follwing fields: readers_id
readers_name ... ...
2. publication_DATABASE with about 40 tables the publication_TABLE has following fields: publication_id
publication_description readers_id ... ...
3. other_DATABASE
4. ...
Is it possible to make following query:
SELECT publication_description FROM publication_DATABASE.publication_TABLE
WHERE publication_DATABASE.publication_TABLE.readers_id = readers_DATABASE.readers_TABLE.readers_id;
or have I to put all tables in one database.
