Thread: How to read oracle table's data from postgre
Hello ,
I want to read oracle database table data from postgre. (like in oracle we can use database links, is there something like this available in postgre).
I tried below -
select dblink_connect('host=.., dbname=..user=.. pwd=..'); but it is giving error database refused connection. Do i need to add anything in oracle datbase server tnsnames. how should be this entry.(since here we are connecting oracle to postgre and not the oracle to oracle)
Thanks in advance..
Regards,
Venkat

I expect SQL/MED plans for the next release may get fleshed out at this year's developer's meeting in a couple of months, should have a better idea who might be working on this by the end of May. -- Greg Smith 2ndQuadrant US Baltimore, MD PostgreSQL Training, Services and Support greg@2ndQuadrant.com www.2ndQuadrant.us
