FW: trigger problem

Hi,

I keep looking for myself and tried as well the following code:

'perform dblink_connect('myconnect','dbname=postgres password=uzleuven');
create view remote as
select *
from dblink('myconnect','select uid from test')
as t1(pat_id text);
perform * from remote where pat_id like '|| query_literal(NEW.pat_id) ||';
return new;
perform dblink_disconnect('myconnect');'

And again I get the same error message as below..

Is this because it tries to make connection for each row in the column??

Thanks,

Jan

Hi,

If I try this to run in a trigger function

'perform dblink_connect('myconnect','dbname=postgres password=uzleuven');
perform dblink_exec('myconnect', 'update test set uploaded = 1 where uid =' || quote_literal(NEW.pat_id) || ' ');
return new;
perform dblink_disconnect('myconnect');'

I get the message

'ERROR: duplicate connection name
SQL state: 42710
Context: SQL statement "SELECT dblink_connect('myconnect','dbname=postgres password=uzleuven')"
PL/pgSQL function "test_update_trigger" line 2 at perform'

This happens only in one of my two databases, anyone an idea?

Regards,
Jan
