I am wondering how to call a postgresql function from Oracle database through Oracle ODBC gateway. I have Oracle gateway configured and dblink named pgrempte created and test in a Oracle databse. I can do select * from “ dbsec”.test_tab@pgremote in Oracle sqlplus and returned result set. How can I call postgresql function named “dbsec”.sp_proc(‘char’,’char2’) from remote Oracle database which has the dbllink named pgremte created? Can it be done?
