Is it possible to write just one query in postgresql database that can also fetch the data from mysql server? With dblink_connect feature of the postgresql database I was able to achieve this goal from another postgresql database but not mysql database. With mysql database it gives me connection refused error.
This is the query I used in a postgresql database and fetched data from another postgresql database:
create extension dblink; select * from dblink('dbname=dbaname port=1234 host=123.456.678.321 user=username password=password', 'SELECT name FROM tbl_customer') AS newTable (mname varchar);

You’ll need to use (and install) a foreign data wrapper.
mysql_fdw is one possible option.
