postgresql - how to access postgres from mysql?

Question

Is it possible to access a Postgres database from MySQL, so that I could run a single query that does joins across tables in both databases?

For example:

SELECT * FROM postgres.db1.table1 as t1, mysql.db2,table2 WHERE t1.id=t2.id;

Answer 1

According to the MySQL CREATE SERVER documentation:

The wrapper_name should be mysql, and may be quoted with single quotation marks. Other values for wrapper_name are not currently supported.

So the answer is no, you cannot do that at the moment, but you can access the MySQL server from within PostgreSQL instead.
